AWS Global Infrastructure
Amazon Services can be hosted in multiple locations worldwide using AWS Global Infrastructure. Amazon allows you to place resources and data in multiple locations to increase performance, fault tolerance, high availability, high availability, cost optimization, and cost optimization.
AWS gives customers the ability to store data and place instances in multiple geographical regions called Region. Each region is a separate collection of AWS resources within a defined geographic area.
Each region is its own distinct geographic area, and each one is completely independent
Each region is a physical area in the world that has cluster data centers
Each Amazon region is designed to be isolated from all other regions. This helps to achieve the highest possible fault tolerance and stability
Communication between regions can be done over the internet. It is important to take appropriate precautions to ensure that data is encrypted.
Data transfer between regions will be charged at the Internet transfer rate, for both the receiving and sending instance.
Resources can’t be replicated between regions unless they are explicitly chosen. There are many factors that drive the selection of a Region.
Latency – To reduce latency, select regions that are close to the targeted user base.
Cost – AWS offers the same set services in all regions. However, the cost of AWS will vary from one region to another depending on the cost (due land, electricity and bandwidth) incurred. It is therefore possible for AWS to be less expensive in one region than the other.
Legal Compliance – Many countries enforce compliance and regulatory requirements to ensure data is stored within the region.
Features – Not all regions offer all AWS features and services. The region selection can be influenced by the Services offered by the region
Each Region is made up of multiple, isolated locations called Availability Zones. Each Availability Zone has its own infrastructure and is designed to be highly reliable.
Each Region has its own Availability Zones, which vary in size from. 2-6)
Each AZ is equipped with independent power, cooling, security, and is connected via redundant, ultralow-latency networks
Each AZ is physically separated from the others so that an unusual disaster like fire or earthquake would only affect one AZ
The AZs are separated geographically from each other but they are located in the same region. This acts as an independent failure area
Multiple tier-1 transit providers are redundantly connected to AZs
All AZ’s within an AWS Region can be interconnected using high-bandwidth and low-latency network over fully redundant metro fiber, which provides high-throughput, low latency networking between AZ.
All traffic between AZ’s are encrypted
Multi-AZ feature allows for the distribution of resources across multiple Arizonas. This can be used to distribute instances across multiple AZs to ensure High Availability
AWS ensures that resources are distributed throughout the Availability Zones of a region by mapping Availability Zones to account identifiers. For example. For example, us-east-1 region with us–east-1a AZ might be different than us-east-1a AZ for a different account. You cannot coordinate Availability Zones between accounts.Edge locations
AWS Edge Locations are locations that are maintained by AWS via a worldwide network data centers for content distribution.
These locations are found in most major cities around the globe and are used by CloudFront to distribute content to end users to reduce latency.
AWS Local Zones bring compute, storage, and database services closer to end users.
AWS Local Zones is a way to run highly-demanding applications that require a single-digit millisecond delay to the end-users. This includes media & entertainment content creation, reservoir simulations, electronic designing auto, and real-time gaming.
