Memorystore
Memorystore is Google Cloud's solution for storing information that needs to be accessed very quickly. Think of it like a super-fast digital storage cabinet that keeps frequently used data ready for immediate use. It's similar to having important documents on your desk rather than filed away in a basement. Companies use Memorystore to make their websites and applications run faster by keeping common information easily accessible. It's particularly useful for things like shopping carts, user sessions, or gaming leaderboards. Similar services include Amazon ElastiCache or Azure Cache for Redis.
