Editor's Notes
- #67: This is compared to “container systems of the past” that were monolithic and tightly coupled Example: hard to reuse components; e.g. take a Docker graphdriver and use it to implement a volume driver
- #87: Towards a Docker Containers as a Service application environment that provides a common interface but separation of concerns for your developers and IT operations team to work together to build, ship and run distributed apps
- #88: ADP operates in a more traditional centralized IT model where IT manages and operates the application and environment ongoing. ADP looked at Docker as they began their transition to DevOps. They were interested in gaining more efficiencies and reuse of code by moving to a shared services model instead of monoliths with a lot of repeat services. ADP has OpenStack for their private cloud and AWS for their public cloud. As part of the transition, ADP would will setup a central marketplace where the shared services apps are available for the app teams. In the ADP example both the environment and ongoing management remains centralized. Use Cases - Transition to Micro services - Enable Dev Ops - CI/CD Why Docker? Need app portability so they can choose to move across AWS / Openstack Agility Streamline lifecycle time to move apps from dev to prod Enable a central repository of “app templates” for common services Portability Support AWS cloud and OpenStack private cloud environments Control Centralized management and control of images, apps and infrastructure Enable secure content lifecycle with integrated image signing and verification
