google cloud

I am working with an organization that wishes to run Drupal on Google Cloud. I have not worked with Google Compute Servers before and am looking for some background material and/or case studies of people (or organizations) that have done this in the (recent) past.

We're ll the process of moving our Drupal 7 online app platform site to a major cloud provider that will include horizontal scaling (multiple nodes for Frontend as well as multiple nodes for MariaDB). We're now considering the optimal solution to scale caching.

We are contemplating substituting standard memcache server with either internal Couchbase memcache server or Redis. The goal is to optimize performance of the site.

We are also contemplating upgrading from php v5.4 to php7.
