1 00:00:00,120 --> 00:00:01,520 ‫So we've seen Amazon S3 2 00:00:01,520 --> 00:00:04,690 ‫as a standalone service, but it is possible for you 3 00:00:04,690 --> 00:00:08,180 ‫to use it in a hybrid cloud type of setting. 4 00:00:08,180 --> 00:00:10,340 ‫So AWS wants you to bridge 5 00:00:10,340 --> 00:00:12,640 ‫between your on-premises environment to AWS 6 00:00:12,640 --> 00:00:14,510 ‫and that's called a hybrid cloud. 7 00:00:14,510 --> 00:00:17,960 ‫So part of your infrastructure is going to be on-premises 8 00:00:17,960 --> 00:00:20,380 ‫and the rest is going to be on the cloud. 9 00:00:20,380 --> 00:00:21,213 ‫Why? 10 00:00:21,213 --> 00:00:23,550 ‫Well, maybe because sometimes you have created, 11 00:00:23,550 --> 00:00:26,380 ‫for example, your on-premises infrastructure first 12 00:00:26,380 --> 00:00:28,180 ‫and you're doing a migration but it could be long 13 00:00:28,180 --> 00:00:30,100 ‫so you can do a long cloud migration 14 00:00:30,100 --> 00:00:33,120 ‫or for security requirements or compliance requirements, 15 00:00:33,120 --> 00:00:36,240 ‫maybe it's your strategy to have part of it on the cloud 16 00:00:36,240 --> 00:00:38,070 ‫and part of it on-premises. 17 00:00:38,070 --> 00:00:39,760 ‫You have really different use cases 18 00:00:39,760 --> 00:00:43,350 ‫for trying to have two different ways of doing IT. 19 00:00:43,350 --> 00:00:46,190 ‫Some of it on-premises and some of it on the cloud. 20 00:00:46,190 --> 00:00:49,200 ‫And Amazon S3, it's a proprietary storage technology, 21 00:00:49,200 --> 00:00:51,840 ‫so this is not something like the EFS service 22 00:00:51,840 --> 00:00:54,260 ‫or NFS protocol we saw from before 23 00:00:54,260 --> 00:00:57,530 ‫that we can use directly on two servers on-premises. 24 00:00:57,530 --> 00:01:00,150 ‫For exposing S3 data on-premises, 25 00:01:00,150 --> 00:01:03,423 ‫you have to use something called a Storage Gateway. 26 00:01:04,680 --> 00:01:08,730 ‫So if you wanted to summarize the storage options on AWS, 27 00:01:08,730 --> 00:01:11,160 ‫the block storage would be EBS 28 00:01:11,160 --> 00:01:13,640 ‫or an EC2 instance store. 29 00:01:13,640 --> 00:01:16,190 ‫The file storage would be a network file system 30 00:01:16,190 --> 00:01:17,880 ‫so Amazon EFS, 31 00:01:17,880 --> 00:01:22,210 ‫and object storage would be Amazon S3 or Glacier. 32 00:01:22,210 --> 00:01:25,350 ‫And where does the Storage Gateway fit in all this? 33 00:01:25,350 --> 00:01:27,660 ‫Well, the Storage Gateway is going to be bridging 34 00:01:27,660 --> 00:01:30,940 ‫your on-premises data and cloud data in AWS. 35 00:01:30,940 --> 00:01:34,700 ‫So your hybrid storage will allow your on-premises systems 36 00:01:34,700 --> 00:01:36,470 ‫to seamlessly use the cloud 37 00:01:36,470 --> 00:01:38,410 ‫to extend the storage capability. 38 00:01:38,410 --> 00:01:40,510 ‫So this can be used for disaster recovery, 39 00:01:40,510 --> 00:01:43,090 ‫backup and restore or tiered storage. 40 00:01:43,090 --> 00:01:45,230 ‫There are different types of Storage Gateway. 41 00:01:45,230 --> 00:01:49,370 ‫There is a File Gateway, there is a Volume Gateway 42 00:01:49,370 --> 00:01:50,890 ‫and a Tape Gateway. 43 00:01:50,890 --> 00:01:52,730 ‫Now you don't need to know all these types 44 00:01:52,730 --> 00:01:54,290 ‫going into the exam, okay? 45 00:01:54,290 --> 00:01:56,330 ‫What you need to know is that the Storage Gateway 46 00:01:56,330 --> 00:01:59,410 ‫allows you to bridge whatever happens on-premises 47 00:01:59,410 --> 00:02:02,170 ‫directly into the AWS Cloud. 48 00:02:02,170 --> 00:02:03,700 ‫So under the scene, 49 00:02:03,700 --> 00:02:05,770 ‫the Storage Gateway will be using Amazon EBS, 50 00:02:05,770 --> 00:02:09,800 ‫Amazon S3, and Glacier behind the scenes, okay? 51 00:02:09,800 --> 00:02:13,650 ‫So from a certified cloud petitioner perspective, 52 00:02:13,650 --> 00:02:15,540 ‫the Storage Gateway is a way for you 53 00:02:15,540 --> 00:02:20,460 ‫to bridge your file systems and your storage on-premises 54 00:02:20,460 --> 00:02:24,200 ‫into the cloud to leverage best of both worlds, okay? 55 00:02:24,200 --> 00:02:25,430 ‫For if you were to do 56 00:02:25,430 --> 00:02:28,670 ‫the AWS Certified Solutions Architect Associate course, 57 00:02:28,670 --> 00:02:30,220 ‫you would need to understand Storage Gateway 58 00:02:30,220 --> 00:02:33,310 ‫a little bit better, but I will save you this right now 59 00:02:33,310 --> 00:02:35,160 ‫for the Certified Cloud Practitioner. 60 00:02:35,160 --> 00:02:35,993 ‫Okay, that's it. 61 00:02:35,993 --> 00:02:36,826 ‫I hope you liked it 62 00:02:36,826 --> 00:02:38,660 ‫and I will see you in the next lecture.
