Des années pendant lesquelles j'ai entendu la mêm rengaine : sécurité, fiabilité, dépendance, fiabilité de l'éditeur, localisation des données, blablabla&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Ceux qui me connaissent savent qu'il n'y a pas de concession à attendre de ma part sur mes convictions. C'est ainsi que j'ai implémenté des solutions Cloud dès que j'ai commencé en tant que décideur, C.I.O, après les avoir recommandé en tant que consultant.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Quel bilan après 2 ans 1/2 de Intuit Quickbase et 1 an 1/2 de Google Apps, pour respectivement 700 et 2500 personnes ?&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;ul&gt;&lt;li&gt;Sécurité : nous n'avons à ce jour déploré aucun sinistre. Nous avons même la possibilité de rendre l'accès à Google Apps quasiment impossible grâce à l'authentification forte récemment déployée.&lt;/li&gt;&lt;li&gt;Fiabilité : avec Google, quasiment aucun problème à déplorer. Avec &lt;i&gt;Intuit&lt;/i&gt;, un passage à vide l'an dernier s'est traduit par 2/3 jours d'indisponibilité. Ce qui est énorme, mais n'a eu aucun impact business dans mon cas&lt;/li&gt;&lt;li&gt;Dépendance : quelle est la différence entre la dépendance à un offreur qui vit de la qalité jour après jour de sa prestation, dans un environnement concurrentiel ou migrer vers une autre solution st quasiment gratuit ? Les éditeurs avec qui nous avons des contrats de licenses nous maltraitent bien plus lorsqu'il s'agit d'étendre le périmètre des licenses à de nouveaux utilisateurs. La transparence des prix du Cloud a au moins cet avantage par rapport aux pratiques des éditeurs qui se rapprochent plus du racket que de la collaboration. (J'ai les noms des voleurs si vous le souhaitez)&lt;/li&gt;&lt;li&gt;Fiabilité de l'éditeur : ce n'est pas un problème si vous vous adressez aux grosses solutions du web. Vous n'aurez pas plus de migraitons que celles imposées par l'arrêt de la commercialisation d'une solution suite à un rachat. Tiens, ça ressemble à ce qu'il m'arrive avec Sun Identity Server suite au rachat par Oracle. (encore eux ?)&lt;/li&gt;&lt;li&gt;Localisation des données : une société mondiale héberge la plupart du temps ses données de type email à 1 seul endroit. La problématique de la location est réellement identique, car elle ne peux en aucun cas être répartie en fonction des lois des pays. Ce qui est vrai pour le siège devient faux pour une filiale. Il faut donc faire "avec".&lt;/li&gt;&lt;/ul&gt;&lt;div style="background-color: transparent; "&gt;Je suis donc totalement satisfait de mes choix. Ils sont moins confortables que si j'avais la complète maîtrise des changements de version, de la roadmap, de la locaiton des données, de la sécurité etc... Mais il sont bien plus efficaces :&lt;/div&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;ul&gt;&lt;li&gt;Coût nettement inférieur aux solutions in-house&lt;/li&gt;&lt;li&gt;Exploitation 24/7&lt;/li&gt;&lt;li&gt;Administration aisée, mes enfants sauraient le faire&lt;/li&gt;&lt;li&gt;Accessibilité mondiale&lt;/li&gt;&lt;li&gt;Infrastructure sécurité bien plus performante que ce que je pourrais faire dans mon entreprise&lt;/li&gt;&lt;li&gt;Disaster Recovery Plan bien meilleur que ce que je pourrais faire. Et tout est compris.&lt;/li&gt;&lt;li&gt;Et surtout : des utilisateurs utilisant toujours la dernière version du logiciel, une informatique généralement conçue en self-service, flexible, rapide.&lt;/li&gt;&lt;/ul&gt;&lt;div style="background-color: transparent; "&gt;Maintenant, tout le monde en parle. Cloud public, cloud privé (foutaise), cloud washing. Everything I do is "cloud".&lt;/div&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;La dernière solution que j'ai eue à évaluer, se disant SaaS, s'adressant aux équipes de paie d'une part, et à tous les employés d'autre part, nécessite l'installation d'un client ICA (Citrix) pour accéder à travers un VPN SSL aux serveurs de l'éditeur. Et l'installation d'ActiveX sur le portail employé. De qui se moque t'on ?&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Editeurs, si vous me lisez, la prochaine fois que vous venez me présenter ce genre de solution en vous prétendant Cloud ou SaaS, vous repartirez avec le goudron et les plumes. Ca ne me fait plus rire, en 2011, d'avoir à perdre mon temps avec des éditeurs&lt;i&gt;has been&lt;/i&gt; qui ne maîtrisent même pas les technologies.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Le précédent éditeur qui m'a appelé sur ce domaine, avait trouvé intéressante ma présentation sur le Cloud lors d'une conférence, et voulait me présenter ses solutions sécurité à base de VPN SSL. Avait-il écouté ? Avait-il compris ?&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Après 2 ans 1/2 du côté Informatique d'Entreprise, je peux vous le confirmer : la plupart des éditeurs livrent des produits mal conçus, mal codés, pas scalables, lents, nécessitant des ressources anormalement élevée, ajoutant plein de contraintes sur le poste de travail.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Chez moi, c'est le cas de l'ERP : son frontal Web ne tient même pas 50 utilsateurs par serveur. Une 'application' (l'accès à un module donné), met 10 à 30 secondes à s'afficher. Lorsque le temps de latence du réseau est supérieur à 300 ms (le cas d'utilisateurs au Brésil pour des serveurs en France par exemple), la performance est extrêment dégradée.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Chez moi, cest le cas de la conso financière. Elle ne fonctionne qu'avec IE. Elle nécessite un paramétrage d'IE qui est incompatible avec l'usage de l'ERP. Sa performance est catastrophique. Certains rapports, un peu lourds, s'affichent en 1 minute en client lourd et en 30 minutes en client web.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;Ces deux dernières solutions appartiennent aux plus gros éditeurs de la planète. La liste est longue. La coupe est pleine. Les mêmes se permettent de nous facturer une maintenance à &gt;20%. Du racket.&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="background-color: transparent; "&gt;La liste est longue.

After 5 years of evolution of this system, someone proposes to re-factor the whole system. At this moment, buying a wonderful ERP that does everything seems to be the best option from an executive point-of-view. And as all ERP are mainly big monolithic applications, after implementation and a few years of new needs and evolutions, the result is the same.&lt;/p&gt;&lt;p&gt;Only loosely coupling the components of the IS provides for flexibility. Because when components are loosely coupled you can:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Make them evolve independently&lt;/li&gt;&lt;li&gt;Support simultaneously various versions of the same interfaces&lt;/li&gt;&lt;li&gt;Easily reuse and assemble existing services to create new ones&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;p&gt;As a result, IS is immune when a component is upgraded to provide for new functionalities. By supporting several versions of the same interface, components can evolve asynchronously. And when the business comes with new requirements it is often easy to fulfil it assembling services that already exist, and are already in production.&lt;/p&gt;&lt;p&gt;Loosely coupled interfaces are in some kind immune when the producer and consumer ends change a little but their interface definition.&lt;/p&gt;&lt;p&gt;You can partly upgrade the producer without changing the consumer.&lt;/p&gt;&lt;p&gt;When you update your main system to provide new capabilities, you want let your clients to continue to access the old capabilities until they get around to upgrading.&lt;/p&gt;&lt;h1&gt;How to do that?&lt;/h1&gt;These things come with SOA.&lt;br /&gt;Be careful, not all SOA. The one who consider that SOA is Remote Procedure Calls with angle brackets will not only fail implementing loosely coupling, but do worse : they will tightly couple applications together by using a huge number of loosely coupled interfaces. It will not be possible to change one system by another because the number of fined grained interfaces will be to important.&lt;br /&gt;&lt;br /&gt;The first important point is to begin to well-define "exchanges" between applications. You will require a reference model of each piece of data that will be exchanged between applications. Note that this model is not a copy of your existing database. The best is to reuse the XML models proposed by the industry you are working for.&lt;br /&gt;&lt;br /&gt;The second important point is to hide implementation technology in your services. Having Web Services whose URI is something.aspx or something.jsp is not hiding the technology behind it. You must define a URI map that is completely independant from technology. I suggest you following the REST design principles.&lt;br /&gt;&lt;br /&gt;The last thing is : keep it simple, and reuse existing vocabularies, adding them constraints, instead of reinventing new ones.&lt;br /&gt;&lt;br /&gt;When you invent a new language, you have to write a validator, a parser, a viewer ...&lt;br /&gt;When you reuse one existing, all these thiongs are free. And it improves the chance to easily integrate with your ecosystem.&lt;br /&gt;&lt;br /&gt;In this area, &lt;a href="http://microformats.org/"&gt;Microformat&lt;/a&gt; have an interesting concept : use XHTML as a container for structured data. XHTML provides you for an existing syntax and some existing semantic as well. Add &lt;span style="font-style: italic;"&gt;class="meta-data"&lt;/span&gt; to your &lt;span style="font-style: italic;"&gt;div &lt;/span&gt;or &lt;span style="font-style: italic;"&gt;span &lt;/span&gt;or whatever elements to give meaning to your data inside the XHTML enveloppe. And human and machine will be able to read these documents.&lt;br /&gt;&lt;br /&gt;Using RSS &amp;amp; ATOM as an enveloppe to exchange data is probably the next big thing. Have a look at &lt;a href="http://code.google.com/apis/gdata/protocol.html"&gt;Google GData&lt;/a&gt;, look at &lt;a href="http://www.netvibes.com"&gt;Netvibes portal&lt;/a&gt;, or &lt;a href="http://www.google.com/ig"&gt;google/ig&lt;/a&gt; portal : they are reinventing the new standard for portlets : a portlet is an RSS feed. All can be an RSS feed : your emails (see Gmail Atom), your information, your calendar (see GCalendar), your contacts (see Netvibes Plaxo extension), your bank account history, your todo list, your clients to call, ...&lt;br /&gt;And these RSS feeds can be shown in your portal, whatever technology you choose : opensource, commercial, hosted portal.&lt;br /&gt;&lt;br /&gt;&lt;h4&gt;Conclusion&lt;/h4&gt;&lt;br /&gt;Loosely coupling is achieved by:&lt;br /&gt;&lt;ul&gt;&lt;li&gt;making the same choice than the others. The vast majority of them. Don't invent XML languages. First consider if you cannot do it with RSS, ATOM, XHTML, UBL (business), Microformats, ODF (Open Document Format)&lt;br /&gt;&lt;/li&gt;&lt;li&gt;reducing the number of coupling points : use coarse grained interactions instead of optimized specific fined grained interactions.&lt;/li&gt;&lt;/ul&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/32499324-115520009805919058?l=e-tricoo.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://e-tricoo.blogspot.com/feeds/115520009805919058/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://e-tricoo.blogspot.com/2006/08/loosely-coupling-helps-cio-to-keep-his.html#comment-form' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/32499324/posts/default/115520009805919058'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/32499324/posts/default/115520009805919058'/><link rel='alternate' type='text/html' href='http://e-tricoo.blogspot.com/2006/08/loosely-coupling-helps-cio-to-keep-his.html' title='Loosely coupling helps CIO to keep his job'/><author><name>François Tricot</name><uri>http://www.blogger.com/profile/10995155589162538200</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://2.bp.blogspot.com/-uAIsbMpzPts/TV2d2C3WLyI/AAAAAAAACIA/ySLBQrkeGM0/s1600/ftricot-256x256_reasonably_small.png'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-32499324.post-115520005342419721</id><published>2006-08-10T01:53:00.000-07:00</published><updated>2006-12-13T22:18:11.941-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='SOA'/><category scheme='http://www.blogger.com/atom/ns#' term='CIO'/><title type='text'>Railway Station Desks are Stateless</title><content type='html'>&lt;p&gt;IT managers do not understand why stateless is scalable and stateful not. They consider it is a religious fight.&lt;/p&gt;&lt;p&gt;Software vendors whose licenses models are price per CPU will find tons of arguments against this model. Their marketing teams are paid for that.&lt;/p&gt;&lt;p&gt;The less performant is your system, the more money you give them.&lt;/p&gt;&lt;p&gt;If your company plans to spend less in IT, then you should consider understanding deeply the difference.&lt;/p&gt;&lt;p&gt;Day-to-day life is bringing us tons of sample that we can use to metaphor architecture design patterns. Railway stations desks are like application servers : they process requests.&lt;br /&gt;&lt;/p&gt;&lt;h1&gt;Some general considerations&lt;/h1&gt;Internet architecture is stateless. Its components do not rely on a state to process the requests.&lt;p&gt;Two models are currently used in software development:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Stateful Application Servers&lt;/li&gt;&lt;li&gt;Stateless Application Servers&lt;br /&gt;&lt;/li&gt;&lt;/ul&gt;Their are two major things people do not understand:&lt;br /&gt;&lt;ul&gt;&lt;li&gt;Stateless Applications Servers can process stateful processes&lt;/li&gt;&lt;li&gt;Stateless Applications Servers can easily handle errors as well as stateful&lt;/li&gt;&lt;/ul&gt;Software engineers and architects coming from client-server do not understand easily that until they build their first stateless services.&lt;br /&gt;If you are not convinced, but openminded enough, read the article, and try yourself.Entering the railway station, I saw that at least 10 free desks, so I went to the nearest.My travel agency is stateful. It gives me a printed copy of the reservation and keeps the original on its desk. I have to come back to this exact desk to confirm the reservation before the 2 days delay.It is a stateful desk. Exactly like a stateful application server. The data is stored on the desk like the application server session stores data for future retrieval in an application server.&lt;br /&gt;&lt;span class="fullpost"&gt;&lt;br /&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.petiteceinture.org/IMG/jpg/attente_gare_du_nord_1.jpg"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 344px; height: 258px;" src="http://www.petiteceinture.org/IMG/jpg/attente_gare_du_nord_1.jpg" alt="Waiting Paris-Nord Railway Station" heigth="50%" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;h1&gt;The story&lt;/h1&gt;&lt;br /&gt;&lt;p&gt;When I worked in Paris, I wanted to book a ticket on Paris-Montparnasse railway station to go from Paris to Toulouse. But I did not know the schedule and the price. I was near the station so I decided to go to get informed, to reserve, then later to check with my family and to buy the tickets.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;h1&gt;Reserving the travel&lt;/h1&gt;&lt;p&gt;The train was leaving at 5 PM on Friday. That sounds good. The agent informed me about the time schedule, and said I have to be careful because this train is always overloaded.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;But I was not sure it was OK with my family, so I reserved my 5 tickets and the agent entered this in its system and gave me a reservation number, valid for 2 days, and printed a sheet with the details of the travel and gave it to me.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;On the sheet it was indicated that I had several ways to get my ticket.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;Come back to any railway station in France, show the sheet, pay and get the tickets&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Connect to the Internet, pay by credit card, get the ticket sent by mail&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Go to an automatic ticket machine, enter the reservation number, pay by credit card, and get the ticket printed by the machine&lt;/li&gt;&lt;/ul&gt;&lt;h1&gt;Getting the tickets&lt;/h1&gt;&lt;p&gt;During the evening, I checked with my family. The price was cheap and the time schedule was convenient. So we decided to buy the tickets.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;The day after, I came back to the railway station.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;It was a busy day. Quite all the desk had a queue. I went to the smallest queue and waited for my turn. I gave the reservation number, paid, and get my tickets.&lt;br /&gt;&lt;/p&gt;&lt;h1&gt;My travel agency&lt;/h1&gt;&lt;p&gt;In my shopping center there is a big store with a travel agency. It is nice as the shopping center is just 2 roads from my home.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;I can avoid going to the railway station to book a ticket. I can go to this travel agency.&lt;/p&gt;&lt;p&gt;The only thing is that if I reserved the train on this travel agency, I have to come back to the same travel agency to pay and retrieve my tickets.&lt;/p&gt;&lt;p&gt;Normal: They are delivering a service and want to be paid for that service.&lt;/p&gt;&lt;p&gt;I can't even go to another travel agency from the same store in another town, because it is not the same business. The store account is not global.&lt;/p&gt;&lt;p&gt;But it is nice, as it is just 2 roads from my home.&lt;/p&gt;&lt;p&gt;And it sells train tickets, flights, hotels, car rental...&lt;/p&gt;&lt;p&gt;Quite all the day, their is nobody, so if you decide to go at this moment, service is fast and personalised. The agent know me. She is nice.&lt;/p&gt;&lt;p&gt;But between 5 and 7 PM, it is hard to get served in less than half an hour. All customers are getting their tickets, vouchers...&lt;/p&gt;&lt;p&gt;And it is good if you find the same agent than the day before, when you completed your file, because she remembers your personal data. She will also find your file in her desk quicker.&lt;/p&gt;&lt;h1&gt;My Railway Station is stateless&lt;/h1&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/916/813/1600/ThreeTiersArchitecture.jpg"&gt;&lt;img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://photos1.blogger.com/blogger/916/813/400/ThreeTiersArchitecture.jpg" alt="3 tiers architecture" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;p&gt;Let's compare this story with a three tiers web application&lt;br /&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;The railway station is the URL where the service is hosted. It has a unique location. As well as there are various channels to buy a ticket, there are also various channels to interact with an organisation suck as internet, WAP mobile phone.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;The desk processes requests, as well as an Application Server processes request.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Eventually, some guide can play the role of a loadbalancer, routing people to the right desk as well as a loadbalancer routes the HTTP request to the right Web &amp; Application Server.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Railway station back-end system is the data tier. It stores permanent data such as the time schedules, and work in progress such as reservations, bookings.&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;br /&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/916/813/1600/RailwayStation.jpg"&gt;&lt;img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://photos1.blogger.com/blogger/916/813/400/RailwayStation.jpg" alt="Railway Station Architecture" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;p&gt;My railway station is stateless. It does not store the date of the booking on the desk. It does not affiliate a customer to a desk. It does not require that I go every time to the same desk. It allows me to begin a process with one desk and to continue it with one other desk. It allows me to choose the desk where the queue is small.&lt;br /&gt;&lt;/p&gt;&lt;h1&gt;How do they manage incidents?&lt;/h1&gt;&lt;p&gt;What can happen between my 2 requests?&lt;/p&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;The train could have been canceled: so, when I try to retrieve the tickets, they propose me another train, later, or an alternative path.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;For any reason, my booking could have been canceled. Airlines do that every day. They have an 'overbooking' process, and sometimes you have booked for a flight and they propose you another flight - and some money for my pain :-). The agent proposes me another train - and no money :-(.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;I could have paid but then the train is canceled: in this case, I get reimboursed at any desk.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;I could have decided not to buy the ticket: then the reservation will end at the end of the delay and will be removed from system.&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;p&gt;In anycase, their are simple solutions to manage incidents. These solutions do not require two-phase commit neither state management on the desk.&lt;/p&gt;&lt;p&gt;In a Web Application, same strategies could be applied. And it does not cost more to implement them that to debug all this functions relying on sessions.&lt;/p&gt;&lt;p&gt;Let's look at excellent article &lt;a href="http://doi.ieeecomputersociety.org/10.1109/MS.2005.52"&gt;Your Coffee Shop Doesn't Use Two-Phase Commit&lt;/a&gt; from Gregor Hohpe. You will understand how you can handle incidents in asynchronous processing models.&lt;/p&gt;&lt;h1&gt;My travel agency is stateful&lt;/h1&gt;&lt;p&gt;Tons of things can happen &lt;/p&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;Unfortunaltely, the desk is very busy, so I have to wait. There is a free desk but all the other people in front of me reserved at this desk at it is the nearest from the entrance, and have to wait here.&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Unfortunately, it is closed. It will open within one hour. Will my reservation be lost within one hour?&lt;/li&gt;&lt;br /&gt;&lt;li&gt;Unfortunately, the print copy on the desk has been lost. The agent who was here yesterday is ill today, and the new does not find the files. I have to redo my reservation. Will I find available seats?&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;p&gt;&lt;br /&gt;But the guy who invented these stateful architecture found some hacks.&lt;br /&gt;&lt;/p&gt;&lt;ol&gt;&lt;br /&gt;&lt;li&gt;&lt;span style="font-weight: bold;"&gt;Session replication&lt;/span&gt; : every time I have a reservation, I go to the copier and I copy it in order to have it on one or several other desks. Just in case my desk is closed when the next transaction will occur. I do not know one project requiring scalability that implemented this without pain.&lt;br /&gt;&lt;/li&gt;&lt;br /&gt;&lt;li&gt;&lt;span style="font-weight: bold;"&gt;Sticky session&lt;/span&gt; : every time the same user come back, it has to go to the same desk. So that he is sure to retrieve the state. It reduce greatly optimize use of your desks/CPU as it block one user to a desk/CPU, whatever it does.&lt;br /&gt;&lt;/li&gt;&lt;br /&gt;&lt;/ol&gt;&lt;h1&gt;Cost &amp;amp; Scalability&lt;/h1&gt;&lt;p&gt;Surely, the two models do not have the same scalability.&lt;/p&gt;&lt;p&gt;In a stateless system, sizing the system is very simple.&lt;/p&gt;&lt;p&gt;You just have to know what is your processing time by CPU and you will find how many transactions per second a CPU will process. The numbers of concurrent users does not matter. 10 users clicking every 5 seconds generates the same workload than 100 users clicking every 50 seconds.&lt;/p&gt;&lt;p&gt;When you size a stateful system, you must know how many customers you will have assigned to one desk, you must know how many concurrent users a CPU can handle.&lt;/p&gt;&lt;p&gt;Just read the sizing recommendations from the software vendor and you will see if the system is statefull or stateless.&lt;/p&gt;&lt;p&gt;Let's imagine this recommendation from the software vendor:&lt;br /&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;You need one CPU for 400 concurrent users&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;p&gt;Let's say that a user has a think time of 20 seconds. So it generates 3 requests per minute.&lt;/p&gt;&lt;p&gt;So the CPU will be able to process 20 requests per second.&lt;/p&gt;&lt;p&gt;Let's say that a normal CPU server with a stateless application can process 1000 requests per second.&lt;/p&gt;&lt;p&gt;It means 1 ms of CPU to create a web page. Normal performance.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;p&gt;Knowing that, buy the technology you want :-)&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/32499324-115520005342419721?l=e-tricoo.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://e-tricoo.blogspot.com/feeds/115520005342419721/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://e-tricoo.blogspot.com/2006/08/railway-station-desks-are-stateless.html#comment-form' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/32499324/posts/default/115520005342419721'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/32499324/posts/default/115520005342419721'/><link rel='alternate' type='text/html' href='http://e-tricoo.blogspot.com/2006/08/railway-station-desks-are-stateless.html' title='Railway Station Desks are Stateless'/><author><name>François Tricot</name><uri>http://www.blogger.com/profile/10995155589162538200</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://2.bp.blogspot.com/-uAIsbMpzPts/TV2d2C3WLyI/AAAAAAAACIA/ySLBQrkeGM0/s1600/ftricot-256x256_reasonably_small.png'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-32499324.post-115519995149455842</id><published>2006-08-10T01:50:00.000-07:00</published><updated>2006-10-29T10:55:14.760-08:00</updated><title type='text'>Management : Coaching</title><content type='html'>&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/916/813/1600/Coaching%20-%20COACH-en.0.png"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://photos1.blogger.com/blogger/916/813/320/Coaching%20-%20COACH-en.0.jpg" alt="Coaching method reminder" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;h1&gt;Coaching&lt;/h1&gt;&lt;p&gt;IT services companies mainly sell the value of their consultants. All they that can increase this value improve their position.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;One staff can grow when:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;He has got new assignments, with new context&lt;/li&gt;&lt;li&gt;He receives training&lt;/li&gt;&lt;li&gt;He receives coaching&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Coaching allows a continuous improvement of staff. Some consultancy firms sell coaching mainly for high level managers. It is useful for managers who have been just promoted, because they have nobody to refer to, no more models to copy, as they are now on the top of the company.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;I think that coaching inside the company provides for excellent results as every coachee is in a personal improvement process.&lt;/p&gt;&lt;p&gt;This article is about giving you the clues to apply coaching within your company. &lt;/p&gt;&lt;br /&gt;&lt;span class="fullpost"&gt;&lt;p&gt;If you are a manager, an expert, a skilled and experienced professional, you would benefit from applying simple coaching methods. As soon as your team will improve its skills, its autonomy, you will win time for more coaching. Your team will be motivated and the results will be better. You will then easily find someone able to take your job and you will be able to have greater position.&lt;/p&gt;&lt;h1&gt;1- Start a coaching session&lt;/h1&gt;&lt;p&gt;Generally, the coach is the cause of a coaching session. He found a problem: the project is stopped, the staff has an unwanted behaviour, and quality is not good enough.&lt;/p&gt;&lt;p&gt;In that case, the coaching session will follow a feedback meeting.&lt;/p&gt;&lt;p&gt;Knowing how to send feedback to the staff is very important.&lt;/p&gt;&lt;p&gt;A lot of us ruin the relationship at this moment, as they do not know how to give a negative / constructive feedback when they found a problem.&lt;/p&gt;&lt;p&gt;I advise you to prepare your feedback session:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;First, look at the facts, the real facts. Avoid inaccuracy, avoid generality, and avoid judging the person. Without facts, feedback will be inefficient, and sometimes not justified.&lt;/li&gt;&lt;li&gt;Then, assess the impact of facts on the context, the project, the personal performance of staff. If there is no impact, then giving feedback is not justified. You are just irritated by the behaviour. Be open-minded and tolerant.&lt;/li&gt;&lt;li&gt;Then, think about the desired outcome. It should be a change in behaviour and not something that cannot be changed. Is their any interest in blaming someone for something he cannot change?&lt;/li&gt;&lt;/ul&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;br /&gt;&lt;a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://photos1.blogger.com/blogger/916/813/1600/Coaching-%20AID-en.0.png"&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://photos1.blogger.com/blogger/916/813/320/Coaching-%20AID-en.0.jpg" alt="Feedback A.I.D. reminder" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;u&gt;Giving feedback is done in 3 steps:&lt;/u&gt;&lt;br /&gt;&lt;/p&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;Explain the facts. Be sure that the coachee agrees with these facts.&lt;/li&gt;&lt;li&gt;Explain the impact of these facts on the personal performance of the coachee, on his colleagues work, on company activities. Be sure that the coachee understands these impacts. It is really important at this moment to listen to the coachee explications.&lt;/li&gt;&lt;li&gt;Explain then the desired outcome, and be sure that the coachee knows and understand the changes you want and can do them.&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Often at this moment, you can propose a future meeting that will be a coaching session, either with you either with another appropriate coach.&lt;/p&gt;&lt;p&gt;If you don’t follow these advises, you could be in some difficulties.&lt;/p&gt;&lt;p&gt;Take for example the case of a staff arriving regularly late at work.&lt;/p&gt;&lt;p&gt;You think that he is too cool with working hours, you meet him in an open space and …&lt;/p&gt;Manager: “You are regularly late, you have to change that!”&lt;br /&gt;Staff: “No, that is not true, when did I arrive late?”&lt;br /&gt;&lt;p&gt;As you did not prepare your meeting, you have no answer to give&lt;br /&gt;&lt;span style="font-weight: bold;"&gt;Result: one joker lost…&lt;/span&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Or …&lt;/p&gt;&lt;p&gt;Staff: « Regularly, no, indeed, yesterday and last week I had to go with my son at the doctor and I arrived at 10. But this morning I came one hour before to balance.&lt;br /&gt;&lt;span style="font-weight: bold;"&gt;Result: one joker lost…&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Or…&lt;/p&gt;&lt;p&gt;Staff: « You are right, I’m arriving every day at 10 and leaving at 20, so I avoid traffic jams. Is there a problem with the quality of my work?&lt;br /&gt;Manager: “Eh, … no”&lt;br /&gt;&lt;/p&gt;&lt;p&gt;As you did not verify that this behaviour had no impact, you have no answer to give.&lt;br /&gt;&lt;span style="font-weight: bold;"&gt;Result: one joker lost…&lt;/span&gt;&lt;/p&gt;&lt;p&gt;You also have to know how to react to several possible attitudes of your staff:&lt;/p&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;He says nothing&lt;/li&gt;&lt;li&gt;He is aggressive&lt;/li&gt;&lt;li&gt;He speaks a lot and does not allow you to explain your view&lt;/li&gt;&lt;br /&gt;&lt;/ul&gt;&lt;br /&gt;&lt;br /&gt;&lt;p&gt;&lt;br /&gt;&lt;b&gt;He says nothing&lt;/b&gt; : ask him an open question (a question he cannot answer by yes or no)&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;b&gt;He is aggressive&lt;/b&gt; : do not follow him. Speak slowly and sweetly and propose to speak about the thing later and calmly.&lt;br /&gt;&lt;br /&gt;&lt;b&gt;He speaks a lot and does not allow you to explain your view&lt;/b&gt; : trying to do like him will not help you. Let him speak until the end, let him know that you listen to him and that it will be fair he listen to you to the end.&lt;br /&gt;&lt;/p&gt;&lt;br /&gt;&lt;p&gt;&lt;br /&gt;A prepared feedback has a lot of benefits. Indeed, the employee perhaps do not realise his behaviour. Listening can provide you new useful information that will change your mind. Listen. You would discover that the only impact of a given behaviour is that you don't like it.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;And, most important, it is the best moment to decide a new meeting to fix the problem - a coaching session.&lt;/p&gt;&lt;h1&gt;2-Assess coaching need&lt;/h1&gt;&lt;p&gt;Coaching aims at helping people to be successful on their work. Firstly, it is important to know what are your possibilities as a coach :&lt;/p&gt;&lt;ul&gt;&lt;br /&gt;&lt;li&gt;the willing to do: does the coachee want to do the job or does he need motivation&lt;/li&gt;&lt;li&gt;the ability to do: is the coachee skilled enough to do the job?
