Container As A Service

Docker Containers as a Service (CaaS)An IT managed and secure application content and infrastructure where developers can self service build and deploy applications

The Docker Journey: The Power of AND

To run these Dockerized applications in production, teams need to secure and manage the infrastructure,

apps and service levels

Control

Speed and simplicity are the #1 drivers leading developers

to try Docker

Agility

By default, the Docker technology, gives apps

(containers) portability across environments

Portability

Continuous IntegrationPre-production environments deliver only 50%

of the Docker value

Docker Containers as a Service (CaaS)

Lessons learned: Avoid these pitfalls

Developers don’t adopt locked down systems

Existing “end to end” solutions break the Docker experience

Beware of lock-in and loss of portability
