What is Amazon Web Services (AWS)? and what makes it so popular?

What is AWS?

AWS stands for Amazon Web Services.

It provides services such as databases, servers to build, deploy, and manage Websites on a remotely located virtual machine for which they charge.

Customers include Netflix, Twitch, Facebook.

Advantages:

Fast
Secure
Reliable
Cost-effective
Well documented
Auto-scaling is easy
Pay for only what you use
Quick and easy to set up a new
server or extend the storage capacity
Avoids the agony of setting up physical
hardware for a server or storage and configuring it

Disadvantages:

Technical support fee.
Common Cloud Computing Problems.
Limitations of services based on region.
Require more time to develop and maintain the more complex applications.

Global Infrastructure:

Regions: clustered data centers.

Availability Zones: Individual data centre that is self-contained, with its own maintenance and security.

Local Zones: Keeps important services like video and gaming, which require no latency, closer to end-users while also offering high bandwidth.

Primary Region: This is the first Region where you established your directory.

AWS Wavelength: Allows developers to create apps with single-digit millisecond latency for end-users and mobile devices.

Edge location: the location closest to the user who is using an AWS service. Instead of a server, a tiny configuration is installed.

Factors to consider while picking a AWS Region:

Compliance: with data governance (Few people govern data to keep it local.)

Proximity to the customer: reduces latency for end-user

Availability of service: Certain services are limited in a few regions.
Pricing: Varies from region to region

Global vs Regional features:

Global features:

Accessible to all regions.

Changes made are implemented to all the regions that are inherited from the primary region

Regional features:

Accessible to particular regions.

Changes are applied only to the corresponding region

Global services of AWS:

Identity and access management (IAM): is a framework of policies and technologies that facilitates the management of electronic or digital identities

CloudFront: fastest CDN service that securely delivers data, media, and APIs to customers globally with low latency

Route 53: DNS service.

Web Application Firewall (WAF): firewall that filters, monitors, and blocks HTTP traffic to and from a web service
