Applications in the cloud
Perception
Reality
“Cloud is about operations and
infrastructure”
The business is concerned with user
services (i.e. dev & ops together)
“All applications make sense in
the cloud”
Only apps with certain usage profiles
are an economic fit for the cloud
“Apps can just be moved to the
cloud for cloud benefits”
Cloud has implications for HOW
applications should be built
Cloud ROI depends on application DNA

“Regular releases
reduce risk”

“Developers, especially for home-grown applications,
may do many nonstandard things (make calls to the
hardware, make assumptions about the network
infrastructure or environment it is running in, and so on).
You have to think differently if you are building
applications that will run across wide-area networks or
across data centers.”
– CIO, software vendor

Application ‘cloud-readiness’
The key application considerations
Performance
An under-performing application can negate the savings promised
by the cloud.
Elasticity
Application elasticity drives cloud economics. Apps must be
designed to scale up for agility AND down for cost savings.
Resilience
In the cloud, it is more important to anticipate and proactively
handle failures.
Security
8
Cloud brings new risks for apps in a shared environment. Security
should be built-in, verified and monitored.

• On and off workloads (e.g. batch job)
• Over provisioned capacity is wasted
• Time to market can be cumbersome

• Keeping up w/ growth is big IT challenge
• Complex lead time for deployment

Resilience: elevated in importance
Resilience
Less control and visibility of the environment
• Network & disk performance variance due to multi-tenancy of cloud
Must design, implement, & test for auto-recovery from failure
• Assume hardware will fail; assume outages will occur; assume your application will fail
“Early customers of [leading cloud provider] found this out the hard way when the
service had a short outage. When it returned, many customer’s applications didn’t.”

Limited control & knowledge

Hypervisors, guest and host
OSs have vulnerabilities
Cloud is a shared

Low control of

You don’t have assurance they
are secure unless you test
Data needs to be encrypted
