## 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
