An availability zone is one or more data centers located close together that are counted as a single availability zone. There are three types of cloud computing deployments: regions which consist of two or more availability zones, availability zones which are discrete data centers with redundant power and networking, and edge locations which are endpoints used for caching content. When choosing an AWS region, consider data sovereignty laws, latency to end users, and available AWS services.

Exam Tips: Understandthe difference between a region, an Availability Zone (AZ and an Edge Location. ● A Region is a physical location in the world which consists of two or more Availability Zones (AZ’s). ● An AZ is one or more discrete data centers, each with redundant power, networking and connectivity, housed in separate facilities. ● Edge Locations are endpoints for AWS which are used for caching content. Typically this consists of CloudFront, Amazon’s Content Delivery Network (CDN

- #7 "Well, what is an Edge location?" Well, an Edge location is just endpoints for AWS, which is used for caching content. So typically, this consists of CloudFront, which is Amazon's Content Delivery Network. And we're going to cover that off later on in the course. But it's just a way of caching content. So if I'm in London, and I'm trying to download a very large file from an S3 bucket in New York, the very first time I access that file, I have to download it directly from New York. If I then want to access that file a second time, or perhaps someone in London needs to access the same file, they don't then need to download that from New York, it's cached at an Edge location. And that means it can be downloaded a lot quicker, so it's going to be cached in London. So instead of downloading it from New York the second time I access it, I can just download it directly from a caching server in London. And that's all that an Edge location is.
- #8 And then we have a whole bunch of different Edge locations as well. So hopefully that's really clear. Hopefully you understand the difference between a Region and Availability Zone and an Edge location. A Region is just a physical location in the world which consists of two or more Availability Zones. An Availability Zone is one or more discrete data centers, each with its own redundant power, networking and connectivity, and they're housed in separate facilities. Availability Zones are spread out enough so that if there was a flood in one area, that's not going to flood in another area. So if there's a sort of local weather event or something, that should only affect one Availability Zone. So just think of an Availability Zone as a data center. Could actually be two or three data centers, but they're very, very close together. So it's counted as one Availability Zone. And then Edge locations are endpoints for AWS, which are used for caching content. Typically, this consists of CloudFront, which is Amazon's content delivery network, and we will have a lecture on that coming up.
- #9 One last thing you will be expected to know for the exam is, why you should choose a particular AWS Region. And there's really three different options. So first of all, data sovereignty laws. So maybe your data can only reside in a particular country. Maybe the UK is about to leave the European Union, or it may or may not. And maybe the data needs to reside in the UK and not within the EU. Or maybe you've got some federal requirements where you have to keep your data within the United States. So that's one reason why you would choose a particular Region. The other reason would be latency to your end-users. So where is the majority of your end-users? If 90% of your customers are in the United States in the Eastern Seaboard, well then you probably want us-east-1 or us-east-2. But if all your customers are in London or in Ireland, then you might want a different Region entirely. And then finally, it's around AWS Services. So us-east-1 always has the most services, it is the primary Region where everything is released. And then it can take time for other Regions to get those services. For example in Singapore, it took an awful long time to get a particular service called Glacier which we'll learn about coming up. So you might choose a particular Region that has a particular service available to it. So those are the three reasons why you should choose an AWS Region.
