Docker Sales and Support

Docker and Docker Enterprise Platform

Docker was an internal tool used with dotCloud for the Platform as a Service (PaaS) company and was released to the public in 2013. The idea for Docker originated from previous attempts at creating independent, isolated applications complete with all operational dependencies bundled into a single container.

Docker uses the Linux Kernel’s virtualization capabilities to run applications using a libcontainer library programmed in the Go language. This makes the execution environment entirely independent from the underlying infrastructure. Specifically, Docker allows resource isolation to reduce the overhead of starting and maintaining virtual machines for application dependencies or service scalability.

This makes Docker perfect for deploying applications on any of the following environments:

  • On-site servers or virtualized data centers
  • Public or Private Cloud environments
  • Bare Metal Servers

Docker packages an application (and all its dependencies) into a container that runs on any Linux server, making it flexible and easily portable. The latest version of Docker also supports Windows applications and environments. The container isolates the applications view of the operating environment while providing resource limiting for CPU and Memory on the box.

Docker Containers

Docker defines a container as a standardized unit of software. The containers are stored as images, which includes the code, runtime libraries, system tools and settings. Images only become containers during runtime, ensuring that resource consumption only occurs once someone accesses the application using the Docker engine.

Docker containers provide:

  • Industry standardized containers, making applications portable anywhere.
  • Lightweight execution at runtime, as the containers share the OS’s system kernel.
  • Secured applications with the strongest isolation by default.

To work, Docker Containers use a daemon called dockerd as a persistent process to handle container objects. The ability to create new environments quickly and regardless for task purpose means development and production lifecycles decrease exponentially. By adopting Docker Containers, companies can drastically increase their Continuous Integration and Continuous Delivery (CI/CD) pipelines.

Docker Product Suite

Docker provides different options for different types of requirements. Docker Enterprise is an end-to-end platform for building, shipping, and running applications. Docker Hub provides individuals and organizations with container images that speed up the application virtualization processes.

Additionally, Docker also provides tools that improve CI/CD pipelines and processes during the Application Lifecycle (ALC).

Docker Desktop

Docker Desktop is a Windows and Mac OS-based application to quickly build and deploy containerized applications. You can deploy production ready units of software on either Kubernetes or Swarm, and Docker Desktop works with any framework or language.

Docker Desktop’s features include:

  • Quick and easy setup without the need for Virtualized Development Environments
  • A complete and certified Kubernetes environment
  • Desktop to Server alignment
  • Templates for Containerized Applications that you can customize according to your own requirements
  • Controls for Enterprise Deployments with lockable settings and endpoint management tools

Docker Desktop also provides supply chain security when integrated with Docker Hub and Docker Trusted Registry.

Docker Development Tools

Additional development tools integrate your Docker Engine and Docker Compose APIs with your CI/CD environment. This improves not only the time it takes to containerize your DevOps lifecycle, but also simplifies how you manage your Docker images and registries.

The Docker Development Tools include:

  • Docker Build for different architecture and environments.
  • Docker App for packaging, installing, and managing containers.
  • Docker Assemble for framework awareness to automate the creation of the Dockerfile.
  • Docker Context for switching between environments such as test, stage, and production.

Docker Enterprise

Docker Enterprise is a centralized container management tool with a single dashboard to monitor your application clusters that includes automated lifecycle management. It also provides policy-based governance and application logging to assist with troubleshooting the entire environment.

It also improves integration between Kubernetes and existing IT Infrastructure and processes, while ensuring scalability of the entire platform.
