A Comprehensive Guide to Aws Global Infrastructure

Introduction

AWS has been spreading its services around the world since its inception, and it currently has around a million dynamic clients,. The global infrastructure of AWS is broadening so that the clients or end-users can now receive higher throughput and lower latency. AWS infrastructure is making sure that data remains in the user-specified region. It has always been ready to create infrastructure for its clients in such a way that they can fulfill their global requirements. 

What is AWS Global Infrastructure?

AWS Global Cloud infrastructure can be called the backbone of all services AWS offers and its data centers, which means it is globally available. With AWS training, grow your cloud computing technical skills and AWS concepts. 

AWS Global Infrastructure Components Consist of:- 

• AWS Regions
• AWS Availability Zones
• AWS Local Zones
• AWS Wavelength Zones
• Edge locations
• Regional Edge Cache

AWS Region

AWS Regions can be called the heart of the Global Cloud. These are actual physical locations all over the world. It consists of the data center clusters with the AWS availability zones. AWS region can consist of 2 or more AZs. Each AWS Region works in isolation from other AWS Regions. This helps in achieving fault tolerance and stability. Resources are not replicated across regions. We only see resources in our region when we see them in the AWS console.

Example of AWS Regions:

US East (Ohio)

US East (N. Virginia)

US West (N. California)

US West (Oregon) endpoint is the default for AWS RDS

AWS Availability Zones

An Availability Zone (AZ) is a collection of one or many data centers that provide services in an AWS Region.Each AZ contains an extra amount of connectivity, power, and networking capabilities, and an excellent geographical distance separates these individual AZs. All these individual AZs are connected through low latency and high throughput networking channels.This fine connectivity and redundancy help them provide scalable and fault-tolerant applications. As we know, AZs in a Region are isolated from each other physically, and applications in these AZs can provide high availability. Isolated metro fibers connect all Availability Zones.

AWS Local Zones

A Local Zone is an extension of an AWS Region that is geographically closer to users. Any VPC from the parent AWS Region can be extended into Local Zones.We can achieve this by creating a new subnet and assigning it to the AWS Local Zone. By doing this, we are extending the VPC to that Local Zone. this subnet works the same as the other subnets in the same vpc.These Local Zones are configured to run high-speed applications—such as media entertainment—that require low latency to service users in nearby geographic locations.

AWS Wavelength Zones

These AWS Wavelength zones provide 5G telecommunications connections inside AWS Regions. These zones provide AWS compute and storage capabilities to service provider's data centers to their 5G networks. Devices that support 5G can use apps that run in these Wavelength Zones and take advantage of 5G bandwidth.

Edge Locations

• These are the endpoints AWS provides and are used for caching content.
• These consist of CloudFront and Amazon's Content Delivery Network (CDN).
• This is not a region but a small location for caching the content.
• Edge locations help reduce latency while providing data to end users, as they are available in all major cities.
• If a user wants to access data, say from Malaysia, his request will be sent to an edge location close to Malaysia for reading of content.

Regional Edge Cache

• AWS announced in November 2016 that Amazon CloudFront will now have a new type of edge location called Regional Edge Cache.
• It lies between CloudFront servers and the edge locations.
• This cache has a larger cache than an edge location.
• Edge location data is removed from the cache while the data is retained at the Regional Edge Caches.
• When the user-requested data is removed and no longer available at edge locations, it retrieves this cache data from the Regional edge cache, not from the Origin servers with high latency.

Aws Cloud Infrastructure Delivery Environments

Customers provide workload and proper services to end users via AWS global cloud infrastructure zones and outposts in different geographical locations through the below infrastructure options: Data Centers: These are scalable and redundant.

Millisecond Latency: Data centers close to users provide single-digit millisecond latency.

5G Availability: 5G speed access with millisecond latency access for mobile devices end users.

Global Reach of AWS Cloud

The size of AWS is explained below as of today:

• The AWS Cloud spans 96 Availability Zones within 30 geographic regions around the world, with announced plans for 15 more Availability Zones and 5 more AWS Regions in Australia, Canada, Israel, NeThere are currently eight AWS Local Zones for ultralow latency applications, with nine more Local Zones on the way. 
• 25 Local Zones and 29 Wavelength Zones for ultralow latency applications.
• 245 Countries and Territories Served.
• 115 Direct Connect Locations.
• The latest status on the global AWS Infrastructure can be found on this page: aws-global-infrastructure

Why Cloud Infrastructure Matters?

• AWS Infrastructure is a very secure, comprehensive, and trustworthy cloud platform that supports many services globally via its various data centers. You can use AWS to deploy your application workloads or build an entire application with a single click and a delay of less than a millisecond.
• AWS supports millions of customers and partners globally. AWS has a vast and global reach. It has a customer base from every industry and all sizes, from startups to big corporates. A comprehensive AWS tutorial will help you understand global architecture, scheduling, pricing, customizations, etc. 

How and Why to Choose AWS Global Infrastructure Components?

Latency & proximity

• The physical distance between the application deployed ( AWS regions and Zones ) and the end user determines the latency and network performance.
• AWS Local Zones are used for ultra-low latency.
• For 5G access, AWS Wavelength Zone is used.
• If the cloud application is connected with on-premise technologies as part of a hybrid model, the performance is highly affected. In a hybrid strategy, local factors influence the performance, such as on-premise network speed, which, in turn, can’t be controlled by AWS.
• If the AWS Region is close to the customer, it is the cheapest option for the user compared to a distant geographic location.
• Amazon also offers services such as AWS Route 53 to automatically direct global network traffic through the most optimal channels to maximize availability and performance.

Cost

AWS pricing varies across Regions because of different CapEx, OpEx, and regulations in different geographic locations. While configuring AWS infrastructure, organizations consider the following parameters:

• Latency,
• Network performance,
• Regulatory compliance. 

AWS offers a cost calculator to estimate the expected costs of AWS services in different regions. The more complex your AWS environment is, the harder it will be to estimate your AWS global cloud infrastructure costs accurately. The cost calculator is an excellent place to estimate expected AWS regions' costs.

Service Catalog Availability

AWS offers an extensive collection of solutions and services across the globe. Although all its services are popular and available among all regions, not all are available across all regions. A detailed breakdown of all services and what region they are available in can be checked here on the AWS Regional Services page.

Correct AWS regions are selected based on current and future needs.

Regulatory Compliance & Security

Regulatory compliance and security primarily affect the choice of AWS regions and zones where we can decide to deploy our applications. Consider the following factors.

Regulatory Compliance: Regulatory specifications like the EU’s General Data Protection Regulation (GDPR) and state require sensitive end-user data for some specific regions.

Data Mobility: Transferring, storing, and processing user data in data centers at remote locations is sometimes considered a violation of compliance regulations, leads to lawsuits, and may also impact the brand's reputation.

Security Requirements: AWS services scatter the data over different geographical data centers to provide multi-availability zone coverage.

Service Level Agreements

AWS has many Service Level Agreements (SLAs)  related to cover its service uptime and penalties for service failures. More details can be found on the AWS Service Level Agreement page.
