Caching Solutions Flashcards
What is Memorystore?
Memorystore is a fully-managed cache solution offered by Google. You must choose Redis or Memcached as the underlying technology.
What is Cloud CDN and how does it work?
Cloud CDN is a service that caches content in PoPs so that it’s closer to users.
When a user makes a request to an application, it first reaches a GFE. The GFE checks to see if the application has Cloud CDN enabled. If so, it uses Cloud CDN to see if the content is stored in cache. If there is a cache hit, the content is immediately returned to the user. If there is a cache miss, the GFE uses the external load balancer to route the request to the application. The application servers the content and If the content is cacheable, it is stored in Cloud CDN and then returned to the user.
