1
00:00:00,180 --> 00:00:04,050
‫So now let's talk about Amazon MemoryDB for Redis.

2
00:00:04,050 --> 00:00:06,810
‫So it's a Redis-compatible, durable,

3
00:00:06,810 --> 00:00:08,880
‫in-memory database service.

4
00:00:08,880 --> 00:00:12,150
‫So the difference between Redis and MemoryDB for Redis,

5
00:00:12,150 --> 00:00:15,420
‫that while Redis' intent is to be used as a cache

6
00:00:15,420 --> 00:00:19,380
‫with some durability, MemoryDB is really a database

7
00:00:19,380 --> 00:00:22,110
‫that has a Redis-compatible API.

8
00:00:22,110 --> 00:00:24,480
‫So it gives you ultra-fast performance,

9
00:00:24,480 --> 00:00:27,480
‫with over 160 million requests per second,

10
00:00:27,480 --> 00:00:29,220
‫so really, really high performance,

11
00:00:29,220 --> 00:00:32,610
‫and it's-in memory data, but it's durable data storage

12
00:00:32,610 --> 00:00:34,800
‫with Multi-AZ transaction log.

13
00:00:34,800 --> 00:00:37,650
‫So this is a different kind of functioning than Redis.

14
00:00:37,650 --> 00:00:40,410
‫It will scale seamlessly from tens of gigabytes,

15
00:00:40,410 --> 00:00:42,750
‫to hundreds of terabytes of storage,

16
00:00:42,750 --> 00:00:45,240
‫and the use cases for Memory-DB for Redis,

17
00:00:45,240 --> 00:00:47,460
‫will be your web and mobile applications,

18
00:00:47,460 --> 00:00:50,340
‫online gaming, media streaming, and so on.

19
00:00:50,340 --> 00:00:52,290
‫So imagine you have a lot of microservices,

20
00:00:52,290 --> 00:00:55,110
‫and they need access to a Redis compatible

21
00:00:55,110 --> 00:00:57,810
‫in-memory database, then this is perfect.

22
00:00:57,810 --> 00:00:59,340
‫You use MemoryDB for Redis.

23
00:00:59,340 --> 00:01:02,040
‫You're going to get ultra-fast in-memory speed,

24
00:01:02,040 --> 00:01:04,320
‫as well as a Multi-AZ transaction log,

25
00:01:04,320 --> 00:01:07,080
‫which is going to be stored across multiple AZ,

26
00:01:07,080 --> 00:01:09,389
‫and will give you access to fast recovery

27
00:01:09,389 --> 00:01:12,240
‫and data durability if you need it.

28
00:01:12,240 --> 00:01:13,260
‫Okay, just an overview,

29
00:01:13,260 --> 00:01:14,640
‫but that should be enough for the exam.

30
00:01:14,640 --> 00:01:17,673
‫I hope you liked it, and I will see you in the next lecture.
