Global Infrastructure for AWS

In our previous articles, we understand what is Cloud and what are the different types of Cloud? But whether it’s a cloud or local system, our data will be physically present on a computer. So today, we will discuss the Global Infrastructure of AWS.

The whole infrastructure for AWS is divided into 2 main parts

• AWS region, and
• Availability Zones

So, now the question is

What is an AWS region?

An AWS Region is a physical location in the world where all the data will be kept in data centres or availability zones. At the time of writing AWS has 26 AWS regions

What are Availablity Zones?

It is a combination of one or more discrete data centres, each with redundant power, networking and connectivity housed in separate facilities in an AWS region.

Benefits of Availability Zones

• Secure: These zones are monitored 24/7 by the AWS team so we can see it is more secure.
• Availability: AWS delivers the highest network availability of any cloud provider. Each region is fully isolated and comprised of multiple AZs, which are fully isolated partitions of infrastructure.
• Performance: AWS Regions offer low latency, low packet loss, and high overall network quality. This is achieved with a fully redundant 100 GbE fibre network backbone, often providing many terabits of capacity between Regions.
• Global Footprint: When deploying your applications and workloads to the cloud, you have the flexibility in selecting a technology infrastructure that is closest to your primary target of users
• Scalability: Customers used to over-provision to ensure they had enough capacity to handle their business operations at the peak level of activity.
• Flexibility: The AWS Global Infrastructure gives you the flexibility of choosing how and where you want to run your workloads, and when you do you are using the same network, control plane, API’s, and AWS services.

Things to remember

• Each AWS Region is completely isolated from other AWS regions.
• Each Availability zones is isolated but all the availability zones in the AWS region are connected through low-latency links.
• AWS Local Zones are a type of infrastructure deployment that places compute, storage, database, and other select AWS services close to the large population and industrial centres.
• AWS Wavelength embeds AWS compute and storage services within 5G networks, providing mobile edge computing infrastructure for developing, deploying, and scaling ultra-low-latency applications.
• With AWS Outposts, you can run some AWS services locally and connect to a broad range of services available in the local AWS Region. Run applications and workloads on-premises using familiar AWS services, tools, and APIs. Outposts support workloads and devices requiring low latency access to on-premises systems, local data processing, data residency, and application migration with local system interdependencies.
