SLAs
What is your cloud-based application’s availability and reliability?
When an application is hosted on-premise, availability and reliability
is your responsibility, and if it’s critical to business operations, you
put a lot of effort into maintaining it.
Again, with the move to the cloud, this becomes the cloud provider’s
concern, but you still need to keep in mind the application’s role in
the bigger picture. How well would the business tolerate moments of
application unavailability and unreliability?
For example, if a cloud-based HR application wasn’t available for a
day or two, it probably wouldn’t impact a supermarket’s business
process.
However, if a cloud-based supply-chain application wasn’t available for even an hour or two, it would wreak havoc
on a supermarket’s business process. The lack of availability would
mean a lack of deliveries, empty shelves, and loss of revenue.
A thorough SLA will communicate to your cloud provider in no
uncertain terms which applications your business counts on the most, and
what the consequences will be should those applications fail.
