How To Move Applications to Containers

in 5 Easy Steps

December, 2016

© 2015 Cloud Technology Partners, Inc. / Confidential 2

It’s all about agility and time-to-market


Things Are Exploding

“In the last two years, companies have

also begun to embrace container

technologies, such as Docker, to help

them standardize and streamline the

way they package and deploy code.”

- RightScale “State of the Cloud Report

2016” (Released last week)


• The ability to reduce complexity by leveraging container abstractions.

• The ability to leverage automation with containers to maximize their portability, and thus their value.

• The ability to provide better security and governance by placing those services around, rather than within

containers.

• The ability to provide better distributed computing capabilities, considering that an application can be divided

into many different domains, all-residing within containers.

• The ability to provide automation services that can provide policy-based optimization, and self-configuration.

Why Containers?

• Lift-and-Shift

– Pros

• Minimal work required to move application

• Faster migration and deployment

– Cons

• Typically does not take advantage of native

features of the cloud platform

• May cost more to operate in a cloud

Comparing Current Approaches to Moving Apps to the Cloud

• Partial Refactor

– Pros

• Only parts of the application are modified

• Faster migration and deployment than

complete refactoring

– Cons

• Only takes advantage of some features of the

cloud

• May cost more to operate in a cloud

• Complete Refactor

– Pros

• Applications typically offer higher

performance

• Applications can be optimized to operate at

lower costs

– Cons

• Much higher cost since much of the

application must change

• Slower time to deployment


Use Case - Containers as a Service

Old Way New Way

• Bring your own technologies

• Standardize

• Portability

• Roll your own PaaS

• Inefficient use of resources

• Solving same problems over & over

• Patching nightmare

• High overhead on management & Ops

VS.
