“It was a natural evolution for us, moving from on-premises hosted .NET applications over to the Microsoft Azure cloud environment...to be able to migrate our applications seamlessly over to the cloud was a hassle-free exercise for us.”

“With Azure DevOps, we can do parallel development, which makes us faster and more flexible in updating our online presence. This benefits our customers, since we can more easily and quickly provide them with the most up-to-date information.”

“With cloud services, we are able to eliminate all points of failure. We have created process and equipment redundancy so if one server fails, then the other one will continue operating. The switch can be made instantly, and the user doesn't even notice the change.”

"I choose Azure PaaS products according to my purpose. The good thing about Azure is that each product has a clear concept and a consistent culture of user-friendliness. All products have the same UI design. There is a line of thought that can not be set more finely. There are times when it is difficult to make detailed settings, but it can be said that it is precisely because there are such restrictions that you can concentrate on how to combine them.”

Yusuke Suzuki, President and CEO of Growth Architecture & Teams

"Azure didn't let us down. More than that, it gave us a way to assure senior management that we could support this massive, global campaign."

“The apps we started with were monolithic, so they didn’t scale well. Azure App Service let us break down those apps into components that could be scaled out separately.”
