Deploying and running applications in Containers is one of the hottest trends in DevOps and IT today. Docker, a containerization platform that lets users easily package, deploy, and manage their applications within containers, is principally responsible for bringing containers to the mainstream. This article provides information about what containers are, their relationship with DevOps, and the benefits derived from container implementation.

What are Containers?

Containerization is a virtualization method for encapsulating software and the minimum set of resources and dependencies necessary for that software to run. Containers encapsulate functionality at a higher level than Virtual Machines (VMs) as they do not typically contain a full operating system or services, rather they have a minimalist OS which makes them orders of magnitude smaller than a typical VM (a number of containers can fit into a typical VM disc footprint) and makes them extremely efficient and portable. Containers, with their stripped down OS and minimal services, are typically much faster to deploy and initialize than a full VM. Containers are extremely flexible and facilitate higher workload densities for deployments on bare metal, virtualized, and cloud based infrastructures.

What do they have to do with DevOps?

Modern data center infrastructure management solutions are helping to change software development. The increasing popularity of virtualization technologies, including containerization, has made infrastructure more available and flexible, supporting agile software development processes and practices while increasing integration and collaboration between development and operations. Containers facilitate DevOps and Continuous Integration (CI), Continuous Deployment (CDep), and Continuous Delivery (CDel) by creating smaller, isolated, and more efficient workload deployment packages that are more easily managed and integrated with CI/CD build pipelines.

What benefits can one gain from Containers?

  • Resource utilization/efficiency (ROI)
  • Standardization and consistency
  • Workload Portability
  • CI/CD efficiency and Rapid Deployment
  • Cloud multi-platform support
  • Security through isolation and segregation of applications and resources
