Module 3 Global Infrastructure and Reliability
Handling availability and fault tolerance
Multiple regions where data centers
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
Edge Locations
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
How to Provision AWS Resources
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.
AWS Elastic Beanstalk
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
AWS Cloud Formation
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.
