The DevOps movement is currently driving a wave of innovations in technology, which are contributing to the development of powerful systems and software development architectures, as well as generating a transformation in “systems thinking”. Game changers like Docker have revolutionized the way system engineers, administrators, and application developers approach their jobs, and there is now a concerted push to iterate on the new paradigms that have emerged. The crystallization of containerization virtualization methods is producing a different perspective on service infrastructures, enabling a greater modularity and fine-grained-ness not so imaginable a decade ago. Powerful configuration management tools such as Chef, Puppet, and Ansible allow for infrastructure to be defined literally as code. The flame of innovation is burning brightly in this space and the concept of the “DevOps engineer” is becoming a reality and not the idealistic myth it appeared to be before. Now that DevOps know roughly where they're going, a feverish development drive is gathering pace with projects looking to build upon the flagship technologies that contributed to the initial spark. The next few years are going to be fascinating in terms of seeing how the DevOps foundations laid down will be built upon moving forward.

The major foundation of modern DevOps development is the refinement of the concept and implementation of containerization. Docker has demonstrated how it can be leveraged to host, run, and deploy applications, servers, and services in an incredibly lightweight fashion, abstracting resources by isolating parts of the operating system in separate containers. The sea change in thinking this has created has been resounding. Still, however, a particular challenge for DevOps engineers working at scale with containers is developing effective orchestration services. Enter Kubernetes (apparently meaning “helmsman” in Greek), the project open sourced by Google for the orchestration and management of container clusters. The value of Kubernetes is that it works alongside Docker, building beyond simply booting containers to allow a finer degree of management and monitoring. It utilizes units called “pods” that facilitate communication and data sharing between Docker containers and the grouping of application-specific containers. The Docker project has actually taken the orchestration service Fig under its wing for further development, but there are a myriad of ways in which containers can be orchestrated. Kubernetes illustrates how the wave of DevOps-oriented technologies like Docker are driving large scale companies to open source their own solutions, and contribute to the spirit of open source collaboration that underlines the movement.

Other influences of DevOps can be seen on the reappraisal of operating system architectures. CoreOS,for example, is a Linux distribution that has been designed with scale, flexibility, and lightweight resource consumption in mind. It hosts applications as Docker containers, and makes the development of large scale distributed systems easier by making it “natively” clustered, meaning it is adapted naturally for use over multiple machines. Under the hood it offers powerful tools including Fleet (CoreOS' cluster orchestration system) and Etcd for service discovery and information sharing between cluster nodes. A tool to watch out for in the future is Terraform (built by the same team behind Vagrant), which offers at its core the ability to build infrastructures with combined resources from multiple service providers, such as Digital Ocean, AWS, and Heroku, describing this infrastructure as code with an abstracted configuration syntax. It will be fascinating to see whether Terraform catches on and becomes opened up to a greater mass of major service providers. Kubernetes, CoreOS, and Terraform all convey the immense development pull generated by the DevOps movement, and one that looks set to roll on for some time yet.
