These services compare favorably to what would be provided by the ideal operations team. After reaching the desired state, they monitor for disruption to that state and restore it when there’s a deviation.īecause of this, orchestration engines provide valuable services. Orchestrators like Docker Swarm and Kubernetes solve the real needs of real teams for turning their desired state into reality. It enables handling many moving parts and keeping the operation up, healthy, and thriving. This type of infrastructure shines in managing complex deployments. Finally, increasing emphasis on continuous deployment makes critical the need for tooling for managing provisioning, deployment, monitoring, and resource balancing.Ĭontainer orchestration provides exactly this. Further, the number of components making up a system may be beyond the capacity of management without automation. In modern environments, teams may not have purely operational specialists. Operations specialists have traditionally dealt with creating environments to handle these concerns and run application workloads. Orchestration of workloads in containers is an umbrella for managing all of these concerns and remedies in an automated way. Finally, virtualization solves problems with resource utility and flexibility. Then we have instrumentation, which deals with visibility and health monitoring. For instance, load balancing addresses scale, fault tolerance, and partition tolerance.

Over time, teams have addressed these problems in ways that have become standard. Among them are availability, fault tolerance, scale, networking, discovery, and cost. Orchestration is the mastermind, focused on the bigger picture. An orchestrator brings together the containers enlisted in the effort into a cohesive whole system. If you think about containers as the infantry in an army intent on serving a system, you quickly realize you need a way to manage coordination and command of those troops.

And it’s silent about how to surface a scalable, fault-tolerant, and reliable service. Docker can run a workload in a container, but all it knows about the lifecycle of a container is that it starts and ends with a given process.īuilding and running containers are foundational to modern software infrastructure, development, testing, and deployment, but it’s not the end of the story. It also doesn’t address questions about load balancing, container lifecycles, health, or readiness.

The problem solved by orchestrationĭocker solves the problem of making sure everything is in place for a process to run, but it doesn’t have much to say about how a container fits into a full system. Teams now apply the development mindset to operations challenges and the operations mindset to development challenges. They do this by improving and simplifying application delivery. This means fewer surprises and better relationships among team members.ĭocker effectively ends the “works on my machine” phenomenon.Ĭontainers thus render team members better able to understand each other’s perspectives. Developers better test the runtime environment for the application. This contrasts with tiresome processes of operations teams trying to build suitable environments from written documents. There doesn’t need to be a distinction between development and operations. When deployments are easy and repeatable, the operations job gets easier. The resulting image is a unit that’s easy to deploy and run as a container.

This means programmers include not only the code they write, but also everything a process needs to execute. This enables a positive shift in the way team members relate to one another.īy writing a Dockerfile that scripts the building of a runtime environment for an application, developers package everything needed to run a given process. It then makes it easy to run the processes that build your system into a cohesive whole. The Docker Engine makes it straightforward to build images that contain all the runtime dependencies your application needs.
