It's easy to get started developing Ruby on Rails apps that run on Google Cloud Platform. And because the apps you create will run on the same infrastructure that powers all of Google's products, you can be confident that they will scale to serve all of your users, whether there are a few or millions of them.
There are three main options for deploying Rails on Cloud Platform.
|Rails deployment option||Use if you want||Don't use if you need||Get started|
|Google App Engine Flexible Environment||
||Rails on App Engine Flexible Environment|
|Google Kubernetes Engine||
||Rails on Kubernetes Engine|
|Google Compute Engine||
||Rails in Compute Engine|
Rails ActiveRecord works best with a traditional SQL database. If you are starting a new project, Google Cloud SQL is a good choice. With a few clicks you can create a MySQL or PostgreSQL database that is fully managed and scaled by Google, with no management on your end. You can learn more by reviewing the Using Cloud SQL for MySQL with Rails 5 tutorial or the Using Cloud SQL for PostgreSQL with Rails 5.
In many situations, there are compelling reasons to use a NoSQL database, for example, scalability or suitability for your data model. Although using Rails models with a NoSQL database can be challenging, it is possible with some limitations. For example, many types of database joins can be expressed in Rails, but are not supported by Cloud Datastore and other NoSQL databases like MongoDB. You can learn more by reviewing our Rails Bookshelf tutorial using Datastore, which uses Datastore as its non-relational database. For a managed, massively-scalable NoSQL solution, consider Cloud Datastore , which is a non-relational database that often scales better than a SQL solution.
To install Memcached on Compute Engine, you can use Cloud Launcher. To install Memcached on either Compute Engine or Container Engine, you can use the Memcached Docker image. Similarly, you can install Redis by using Cloud Launcher or the Redis docker image.
