WEBVTT 00:01.050 --> 00:03.480 -: In the last section, we put together our RDS instance 00:03.480 --> 00:05.010 and we're just gonna let it do its thing 00:05.010 --> 00:06.660 as it creates that database. 00:06.660 --> 00:08.760 While that's working, we're going to flip on 00:08.760 --> 00:09.990 over to another dashboard 00:09.990 --> 00:13.920 and create our Elastic Cache instance as well. 00:13.920 --> 00:15.780 So I'll click on services up at the top 00:15.780 --> 00:18.630 and I'll search for Elastic Cache. 00:18.630 --> 00:20.910 And okay, I've been saying Elastic Cache. 00:20.910 --> 00:25.383 I guess it's really ElastiCache, whatever, all the same. 00:27.090 --> 00:29.070 Okay, so once over here, we're gonna scroll down 00:29.070 --> 00:32.430 a little bit and we really want to launch a cluster 00:32.430 --> 00:33.263 but it's showing me this 00:33.263 --> 00:35.130 kind of annoying dashboard right here. 00:35.130 --> 00:37.530 Let's try clicking on Redis on the left hand side 00:37.530 --> 00:39.873 and then we'll find the Create button up here. 00:41.610 --> 00:42.750 So then this is going to walk us 00:42.750 --> 00:44.880 through the process of creating a cluster. 00:44.880 --> 00:46.050 Now the interesting thing here is 00:46.050 --> 00:48.720 we are specifically making a cluster. 00:48.720 --> 00:51.660 So technically when you make an ElastiCache instance 00:51.660 --> 00:55.050 we are getting a copy of Redis, but there's some kind 00:55.050 --> 00:58.590 of separate nodes that just relay information 00:58.590 --> 01:00.668 from the primary Redis node. 01:00.668 --> 01:03.090 Way more detail than we really need to go in. 01:03.090 --> 01:04.140 Just so you know essentially we're 01:04.140 --> 01:06.660 getting a very high powered copy of Redis 01:06.660 --> 01:10.170 that would do really really well if we had a lot of traffic. 01:10.170 --> 01:12.960 Now, by default, we don't really get the cluster created 01:12.960 --> 01:15.180 unless you select that little option right there. 01:15.180 --> 01:18.480 We do not need a cluster so we're just going to leave it set 01:18.480 --> 01:21.063 as Redis without that check box checked. 01:22.770 --> 01:25.770 So we'll throw a couple of options in here for the name 01:25.770 --> 01:29.490 I will enter in Multi Docker Redis. 01:29.490 --> 01:31.290 We don't need a description. 01:31.290 --> 01:33.750 We can leave just about everything else on here 01:33.750 --> 01:36.780 at the default, except for the node type. 01:36.780 --> 01:38.850 So the default node type is a very 01:38.850 --> 01:40.440 expensive little instance. 01:40.440 --> 01:42.300 You would pay a lot of money for this thing 01:42.300 --> 01:46.050 so we want to 120% make sure that you do not 01:46.050 --> 01:48.090 use the default selection here. 01:48.090 --> 01:50.490 So we'll click on the little dropdown 01:50.490 --> 01:52.800 and then we're going to go to t2 01:52.800 --> 01:55.200 and we want to do cache.t2.micro 01:55.200 --> 01:57.270 which is the cheapest copy around. 01:57.270 --> 01:58.380 It's also the lowest performance 01:58.380 --> 02:00.270 but of course our application doesn't really 02:00.270 --> 02:03.660 have very high performance demands, and we'll click on Save. 02:03.660 --> 02:06.480 Now, I want you to really verify right here 02:06.480 --> 02:09.840 that we do in fact have the cheapest option selected 02:09.840 --> 02:12.240 which should be a cache.t2.micro. 02:12.240 --> 02:13.950 If you have anything else selected 02:13.950 --> 02:16.353 you will pay some dollars for it. 02:17.460 --> 02:20.220 We then get asked for the number of replicas. 02:20.220 --> 02:21.900 In this case replicas would be kind of those 02:21.900 --> 02:24.840 separate nodes that kind of supercharge your copy of Redis. 02:24.840 --> 02:27.810 Again, kind of outside the scope, we don't need any replicas 02:27.810 --> 02:30.900 because we definitely do not have high performance demands 02:30.900 --> 02:31.980 for our application. 02:31.980 --> 02:33.933 So I'm gonna change replicas to none. 02:35.100 --> 02:37.800 All right, so now we get asked a couple 02:37.800 --> 02:38.760 of other settings over here. 02:38.760 --> 02:40.800 Some of these are just a little bit nasty. 02:40.800 --> 02:43.530 We get asked to create a subnet for this. 02:43.530 --> 02:44.700 We'll create a new subnet. 02:44.700 --> 02:46.830 This has to do a little bit with security. 02:46.830 --> 02:48.390 We don't really need to focus on the details 02:48.390 --> 02:49.530 of the thing too much. 02:49.530 --> 02:52.050 All we need to do is put in some name right here. 02:52.050 --> 02:53.913 I'll say Redis Group. 02:55.080 --> 02:58.770 The one thing we do care about is marking the VPC ID as the 02:58.770 --> 03:00.480 default VPC. 03:00.480 --> 03:02.760 And so if you have a fresh AWS account 03:02.760 --> 03:05.400 or if you've never created any other VPCs 03:05.400 --> 03:07.590 the only option right here will be the default 03:07.590 --> 03:09.870 VPC that is created for your region. 03:09.870 --> 03:12.600 And so you will want to select that default VPC 03:12.600 --> 03:15.420 so that it's in the same kind of networking group 03:15.420 --> 03:18.360 as the RDS instance we put together already 03:18.360 --> 03:20.190 and the Elastic Beanstalk instance that we 03:20.190 --> 03:21.393 put together as well. 03:22.890 --> 03:24.540 And then for the subnets 03:24.540 --> 03:26.280 we can just check both these right here 03:26.280 --> 03:27.480 and it's just gonna give us access 03:27.480 --> 03:29.670 to those different subnets. 03:29.670 --> 03:30.900 All right, and that's pretty much it. 03:30.900 --> 03:32.550 You'll notice that we also have the option to 03:32.550 --> 03:34.020 select a security group right here 03:34.020 --> 03:34.853 but we're gonna take care 03:34.853 --> 03:36.690 of the security group in just a little bit 03:36.690 --> 03:39.360 as a little follow up to all this stuff. 03:39.360 --> 03:41.010 So I'll scroll on down to the bottom 03:41.010 --> 03:42.453 and I'll click on Create. 03:43.920 --> 03:44.850 And that's pretty much it. 03:44.850 --> 03:49.360 It's now creating our instance of a Redis group of 03:50.220 --> 03:53.190 I don't know, cache instances, whatever you wanna call it. 03:53.190 --> 03:54.270 All right, so we gotta wait for this thing 03:54.270 --> 03:55.103 to be created as well. 03:55.103 --> 03:57.300 So we'll take a quick pause and when we come back 03:57.300 --> 03:59.700 to the next section we're gonna do the last step, 03:59.700 --> 04:01.920 which is to wire all this stuff up 04:01.920 --> 04:03.390 with a common security group 04:03.390 --> 04:05.640 and apply that security group to the Elastic Beanstalk, 04:05.640 --> 04:08.100 RDS, and EC instances. 04:08.100 --> 04:10.563 So quick pause and I'll see you in just a minute.
