GC and Azure are great tools and I see many people complaining about the lack of them on DeployStack, but they are quite advanced options comparing to other services, so they don't really fit well in, let's say the 'Hosting' category (they have much more tools than just hosting, they could replace your whole tech stack). And I wanted DeployStack to be used as "choose your own tech stack" - if you need only hosting, those are the companies that are good and cheap with just hosting. If you already have a website but need to get some statistics - here are tools for uptime monitoring and here are some for analytics.
Anyway, thanks for mentioning GC and Azure, I will keep that in mind and try to add some more advanced sections in the future, where they would fit perfectly.
