Introduction

We usually save a lot of pictures, files, documents, etc., on our devices. But what if we lose it or the device gets damaged, and we can’t use it anymore? So to overcome such storage issues, we have a storage facility - “Cloud” depending on the size and the availability of our information. These clouds store our data, and we access it whenever necessary. 

Cloud computing is a technology that uses remote servers to store, access, and manage data online. The data can be of any form like audio, video, files, images, text, etc. Cloud computing is highly reliable as we can access the data on the cloud from anywhere and on any device. The cloud offers us services based on our requirements and our purpose. This article will discuss the most used and the top cloud service  - AWS.

Amazon Web Services

Amazon Web Services - mostly known as AWS, is a cloud service provided by Amazon. It uses distributed IT infrastructure to provide resources to all the users. It provides various services like Saas(Software as a service), Paas(Platform as a service), and Iaas(Infrastructure as a service). The AWS provides high security to users' data and allows them to access it anywhere. Let’s discuss the Global Infrastructure of AWS in this article.

Global Infrastructure of AWS

The Amazon Web Services are used globally by billions of users. The Global Infrastructure is divided into small geographical areas/regions. They are further divided into availability zones. The AWS Cloud currently has 26 geographic regions worldwide with 84 Availability Zones within them, and 24 more Availability Zones, eight more AWS Regions in  New Zealand, Spain, Switzerland, Australia, Canada, India, Israel, and United Arab Emirates (UAE) coming soon. The AWS Global Infrastructure consists of the following components.

  • Region - It is a physical location where the data centers are clustered around the globe.
  • Availability zones - a group of logical data centers with redundant power, networking, and connectivity in an AWS Region. Each region will be separated into at least two availability zones that must be isolated. If one zone fails to function correctly, the other zone will operate fine without any effect.
  • Edge locations - a site that the CloudFront uses to cache copies of the user's content for faster delivery at any location.
  • Regional edge caches are the CloudFront locations deployed globally to the viewers between the origin server and global edge locations.
