If our web-app goes down our
contact form will remain working
Our web-app has less
responsibilities with fewer things
getting in the way of our primary
development
Our contact form is built using
simple javascript making it easy
for anyone come in an update it.

Provisioning
*
CloudFormation Infrastructure as Code eg write a script that at a press of button
create or destroy all the resources we need to run our service
ELB Elastic Load Balancing distribute incoming traffic across multiple
availability zones or based on a set of rules
AutoScaling Groups Create or Destroy servers to meet the current traffic demand.
EC2 Elastic Cloud Computing servers where we can choose our OS,
Memory, Storage and configure it for our web-application

*Region and scenarios are fake to make a point
Planning for Doomsday
Our DataCenter was Flooded.
Always run your web-app in two data centers (Availability Zone)
eg. Toronto West, Toronto East

All data centers destroyed in Toronto due to a Nuke
Always run your web-app in two different locations (Regions)
eg. Vancouver, Toronto

The Dragon’s want to invest and we have insane amount of traffic!
Our service should automatically create new servers to meet the demand
Auto Scaling Groups

Elastic Beanstalk Opsworks Cloudformation DIY eg. EC2
Infrastructure
As Code

If a datacenter fails, our web-app
will failover to another
datacenter
If all datacenters in a region fail
our web-app will failover to
another set of data centers in
another region
If we have an unexpected
amount of traffic our web-app
will scale to meet this demand.
