Fuelled by the drive to implement DevOps in IT management, container technologies like Docker make life easier for organizations that embrace cloud technologies as the default model for deploying applications in enterprise and customer markets.
While container technology has been around a while, cloud services have made application portability a prime point worth thinking about in deployment.
If you haven’t heard of Docker, you’re pretty late to the party. Docker is an open platform for developing, shipping, and running applications in a loosely isolated environment called a container. Containers package applications with their own dedicated file system, storage, CPU, RAM, and other requirements, guaranteeing that the apps will always run the same without virtualizing the hardware itself. Since they only abstract the operating system kernel, containers are significantly leaner than your average hypervisor.
You might be late to the party, but that just means the party is in full swing.
What does this mean for Docker training?
You have more options than ever to get your hands dirty with Docker.
Michael Mullany has been tracking Docker momentum using LinkedIn profiles, and his end of 2016 report reveals a whopping 160% growth in Docker keywords.
Here are some of the most notable new ways that you can start using Docker today:
- Microsoft Server. Containerization is gaining a very steady foothold in production environments of the enterprise applications world. Last October, Microsoft announced plans to implement Docker container technology in Windows Server 2016. Microsoft’s partnership with Docker involves extending the Docker API and toolset to support Windows Server Containers allowing Hyper-V Containers to be deployed using the magic of Docker as well as use the exact same packages that run in Windows Server Containers.
- Docker in an Agile Ethos. Docker has strategically placed itself at the forefront of containerization using a specific set of strategies. They were the first to develop a standard way to build out a container workload so that it could be moved around and still run in a predictable way in any container-ready environment. In addition, by ensuring that it can easily integrate with other DevOps tools such as Puppet, Chef, Salt or Ansible, Docker is constantly providing a variety of options when it comes to provisioning and configuration management.
- Docker swarm on AWS. Last year, version 1.12 of Docker introduced a new feature called swarm mode. A swarm is a cluster of Docker engines, or nodes, which allow you to deploy services across multiple nodes. This enables better management options for organizations running in huge environments, particularly large cloud service providers. Every node in a swarm can reach every other node, and is able to route traffic where it needs to go, providing capabilities for enhanced resilience and load sharing. A Docker Swarm cluster also provides system administrators with the ability to add or subtract container iterations as computing demands change.
- Docker in Data Centers. Docker Datacenter delivers Containers as a Service (CaaS) environment, which allows developers to work with images that are approved by operations. By learning to work with Docker, any engineer working with Docker earns the capacity to be a team player as it brings down the wall that has separated developers from system administrators, which too often prevents organizations from delivering quality applications that meet business needs.
- Putting the “Ops” into DevOps. Docker is not only a primary tool for a developer, but also comes in handy for system administrators in operations domains, as well as software and infrastructure engineers. Any organization that has chosen DevOps as the methodology for managing their IT services benefits immensely from having employees with knowledge and experience in Docker, since it supports the values of continuous integration, testing, delivery, and deployment of applications. Having Docker in your learning portfolio shows that you’re aware that speed and quality are the most important aspects of what a business expects from the cloud, along with some additional benefits.
