‫So now let's talk about Amazon MemoryDB for Redis.
‫So it's a Redis-compatible, durable,
‫in-memory database service.
‫So the difference between Redis and MemoryDB for Redis,
‫that while Redis' intent is to be used as a cache
‫with some durability, MemoryDB is really a database
‫that has a Redis-compatible API.
‫So it gives you ultra-fast performance,
‫with over 160 million requests per second,
‫so really, really high performance,
‫and it's-in memory data, but it's durable data storage
‫with Multi-AZ transaction log.
‫So this is a different kind of functioning than Redis.
‫It will scale seamlessly from tens of gigabytes,
‫to hundreds of terabytes of storage,
‫and the use cases for Memory-DB for Redis,
‫will be your web and mobile applications,
‫online gaming, media streaming, and so on.
‫So imagine you have a lot of microservices,
‫and they need access to a Redis compatible
‫in-memory database, then this is perfect.
‫You use MemoryDB for Redis.
‫You're going to get ultra-fast in-memory speed,
‫as well as a Multi-AZ transaction log,
‫which is going to be stored across multiple AZ,
‫and will give you access to fast recovery
‫and data durability if you need it.
‫Okay, just an overview,
‫but that should be enough for the exam.
‫I hope you liked it, and I will see you in the next lecture.
