Deis is a prominent tool in the DevOps landscape, designed to simplify the deployment and management of applications across multiple environments. It is an open-source Platform as a Service (PaaS) that leverages container technology to provide a flexible, efficient, and scalable solution for software development and delivery.
Deis is built on top of Docker and Kubernetes, two of the most popular technologies in the DevOps world. It provides a high-level, abstracted interface for managing these underlying technologies, allowing developers to focus on writing code rather than managing infrastructure.
Definition of Deis
Deis is a platform that allows developers to build, deploy, and manage applications in a containerized environment. It is a PaaS, meaning it provides a platform upon which applications can be developed and run, without the need for developers to manage the underlying infrastructure.
Deis is built on top of Docker and Kubernetes. Docker is a containerization technology that packages an application and its dependencies into a single, standalone unit that can run on any system that supports Docker. Kubernetes is a container orchestration platform that manages the deployment, scaling, and management of containerized applications.
Deis Workflow
The Deis Workflow is the main component of Deis. It provides a simple, Heroku-like workflow for deploying and managing applications. With Deis Workflow, developers can easily push code to a Git repository, and Deis will automatically build, package, and deploy the application in a containerized environment.
Deis Workflow also provides features for managing application configuration, scaling applications, and managing application health and availability. It integrates with popular continuous integration/continuous deployment (CI/CD) tools, making it a powerful tool for DevOps teams.
Deis Helm
Deis Helm is another component of Deis. It is a package manager for Kubernetes, allowing developers to easily deploy and manage applications on a Kubernetes cluster. Helm packages, known as charts, are a collection of files that describe a related set of Kubernetes resources.
With Deis Helm, developers can easily install, upgrade, and manage applications on a Kubernetes cluster. It provides a simple, declarative syntax for defining applications, making it easy to manage complex applications with many components.
History of Deis
Deis was originally developed by a company called OpDemand, which was founded in 2011. The initial version of Deis was released in 2013, and it quickly gained popularity due to its simplicity and ease of use. In 2017, Microsoft acquired Deis, and the Deis team now works on Azure, Microsoft's cloud platform.
Despite the acquisition, Deis remains an open-source project, and it continues to be developed and maintained by a community of contributors. The project is governed by a steering committee, which is responsible for overseeing the project's direction and making decisions about its future.
Deis and Docker
Deis was one of the first platforms to fully embrace Docker, the popular containerization technology. From the beginning, Deis was designed to leverage Docker's capabilities to provide a flexible, efficient platform for deploying and managing applications.
Deis provides a high-level interface for managing Docker containers, allowing developers to focus on writing code rather than managing infrastructure. It also integrates with Docker's ecosystem of tools and services, making it a powerful tool for building, deploying, and managing containerized applications.
Deis and Kubernetes
Deis also fully embraces Kubernetes, the popular container orchestration platform. Kubernetes provides the underlying infrastructure for managing containers, and Deis provides a high-level interface for managing this infrastructure.
With Deis and Kubernetes, developers can easily deploy and manage complex, multi-component applications in a containerized environment. Deis provides features for managing application configuration, scaling applications, and managing application health and availability, all on top of Kubernetes.
Use Cases of Deis
Deis is used by organizations of all sizes, from small startups to large enterprises, to simplify the deployment and management of applications. It is particularly popular in the DevOps community, where it is used to facilitate continuous integration and continuous deployment (CI/CD).
One of the main use cases of Deis is for deploying and managing microservices. Microservices are a software architecture style where applications are composed of small, independent services that communicate with each other. Deis, with its support for Docker and Kubernetes, is an ideal platform for deploying and managing microservices.
Continuous Integration and Continuous Deployment
Deis is often used in conjunction with continuous integration and continuous deployment (CI/CD) tools to automate the process of building, testing, and deploying applications. With Deis, developers can easily push code to a Git repository, and Deis will automatically build, package, and deploy the application in a containerized environment.
This makes Deis a powerful tool for DevOps teams, as it allows them to focus on writing code and delivering value, rather than managing infrastructure. It also helps to ensure that applications are always in a deployable state, and that they can be deployed to production at any time.
Microservices Architecture
Deis is also often used for deploying and managing microservices. Microservices are a software architecture style where applications are composed of small, independent services that communicate with each other. This architecture style is well-suited to containerization, as each service can be packaged into its own container, and these containers can be managed independently.
With Deis, developers can easily deploy and manage these microservices in a containerized environment. Deis provides features for managing application configuration, scaling applications, and managing application health and availability, making it an ideal platform for deploying and managing microservices.
Examples of Deis in Action
There are many examples of organizations using Deis to simplify the deployment and management of applications. For example, Mozilla, the organization behind the popular Firefox web browser, uses Deis to manage its web properties. With Deis, Mozilla was able to reduce its infrastructure costs and improve its deployment processes.
Another example is The New York Times, which uses Deis to manage its content management system. With Deis, The New York Times was able to streamline its deployment processes and improve its ability to deliver content to its readers.
