Cost Effective
No up-front cost
We pay for what we consume
Secure
Service provider takes care of physical security
Allows very granular control on the security options on services
Scalability
Process of adding or removing resources
Increasing Size (Vertical Scalability)
Increasing Amount (Horizontal Scalability)
Elasticity
Auto Scaling (adding/ removing) of resource dynamically based on demand
Agility
The ability to quickly provision resources as per need
When using on premise resources this process could take up to months
Fault Tolerance
The ability of resources to remain up and running during component and service failure
This is achieved by maintaining multiple copies of the resources
Disaster Recovery
Creating copies of the required resources in two separate Azure Regions and setting up replication between them to so that they are up to date and then setting up an DNS between these two regions so that the traffic to the resource can be automatically redirected to the working region
This is an type of Fault Tolerance that is provided for dealing with major disruption to services that can be caused by Natural Disasters
High Availability
It is the metric that measures the uptime of the resource
Downtime can be caused due to planned maintenance or due to resource failure
Cloud providers at a minimum try to aim for four 9s availability
