Module 3 Global Infrastructure and Reliability

Global Infrastructure

You have the choice of selecting the region your app is stored and operate in
Can run in other data centers in different places
- Having one building it is single point of failure
Prevent issues with loss of connection to that data center
- Have second data center - but costs a lot
- Store back ups, but slow to bring back up
Inside each region (all over the world) have multiple data centers
- each region is connected (fttp)
- Each region is isolated, and secured using your own configuration
  - ie no data must leave that region unless you set it to
choice region, allows having app closer to consumer
Decision in choosing the region:
- Compliance: does it meet the laws? Do I have to run it that region to access those customers
- Proximity: closer to customer the faster it gets to the clients
- feature availablity: Not regions have all features you want
- pricing: Different regions costs more
Availability zone
- a single data center or a group of data centers within a Region
- Not built next to each other (ie same building)
  - located tens of miles apart from each other.
  - Have low latency and isolation if disater hits an AZ
- Best practice, to run across at least two AZ in a region
  - Have 2 EC2 instances in a scaling group, but placed in different AZ in the region

CDN
site that Amazon CloudFront uses to store cached copies of your content closer to your customers for faster delivery.
Handles serving customers not close to a region
Instead of moving data to a new region, can use a copy/cache from a region further away,
Provides low latency, high transfer speed
Issues with stale or inconsistent data, when to expire cache
Seperate from regions
Run DNS (Route 53) also
AWS Outpost
- create an amazon datacenter in the your building, run by amazon but isolated to your building

Everything AWS is an API call to provision, configure, and manage your AWS resources.
AWS Management Console
- GUI
- includes wizards and automated workflows
- AWS Console mobile application to perform tasks such as monitoring resources, viewing alarms, and accessing billing information
AWS Command Line Interface (AWS CLI)
- control multiple AWS services directly from the command line on multiple OS
- automate the actions that your services and applications perform through scripts
software development kits (SDKs)
- SDKs enable you to use AWS services with your existing applications or create entirely new applications that will run on AWS.

provide code and configuration settings, and Elastic Beanstalk deploys the resources necessary to perform the following tasks:
- Adjust capacity
- Load balancing
- Automatic scaling
- Application health monitoring

treat your infrastructure as code
declarative
build an environment by writing lines of code instead of using the AWS Management Console
provisions your resources in a safe, repeatable manner
It determines the right operations to perform when managing your stack and rolls back changes automatically if it detects errors.
