Do I need to make changes to the source codes of the site if a regular host changes to a cloud one?

Question

ASP.NET

Suppose I have a specific site implemented on ASP.NET MVC 4. The site is a classic average directory with about ≈ 10000 items in it. There are functions such as search, filtering by parameters, registration / authorization, admin panel, user's personal account , adding/editing your catalog items.
Before that, I hosted the site on traditional web hosting, not cloud hosting. Now I would like to upload my website to Microsoft Azure cloud hosting. Do I need some optimization/change of source codes or configuration files of my ASP site in case of cloud hosting? Or can you leave everything as it is, upload it to cloud hosting and reap the benefits of cloud technologies?

Answer 1

Some dances with a tambourine will have to be done. This will mainly affect the configuration files of the project (change the ConnectionString to the database when it is migrated to the cloud), if the code architecture is initially built correctly (without hardcode, for example, in places where data is accessed and so on, who has a headache). As well as general project settings, perhaps.
I asked the question earlier, but I personally didn’t get to practice. But there is a lot of information on this subject both on official resources and on blogs. In Russian, it is also enough.
