Perry Clarke is well back with another blog post and Geek Out with Perry episode where he chat about availability for Exchange Online in the Office 365 service.
Perry shares some insights on the framework that the team uses when designing reliability and availability as well as discusses with me how the team evolved their thinking as we transitioned from mainly creating Exchange as on-premises software to delivering Exchange as service.
"In this video, I cover some of the areas the Exchange team has focused on as our responsibilities have evolved from selling on-premises software to also encompass managing a service. The most interesting aspect, is the extra focus that is applied to making sure that the isolation models in the service are well thought through. On-premises scenarios provide isolation for free since each company's deployment is very heavily isolated from every other one. To get efficiencies of scale, cloud services create the risk of tightly coupling the whole deployment so that one mistake or design flaw can cause failure for millions of customers," Clarke said.
