OpenShift versus Docker | Enterprise Storage Forum

0

Containerization has simplified the development, administration, and distribution of applications across various frameworks for developer teams. Openshift and Docker are well-known containerization technologies, which provide sophisticated functionality.

OpenShift is a Kubernetes platform developed by Red Hat, a developer tools provider. At its core, Openshift integrates container technology from Kubernetes and Docker. The platform enables developers to streamline workflows in application development, while maintaining enterprise-grade security and comprehensive multi-tenant functionality. The OpenShift platform has seen a 28% gain usage in 2021, according to Datadog, translating the platform’s popularity into cloud container technology.

Docker is a leading open-source container-as-a-service (CaaS) platform that provides a comprehensive set of modern tools needed to quickly build, deploy, and integrate software. Docker is used in continuous integration and continuous delivery (CI/CD) processes to assess code efficiency.

With the proliferation of container technology, due to its characteristics that have made application development faster and more efficient, it is clear that most companies are beginning to adopt them in their operations. For instance, 46% of companies surveyed ranked container-based applications as their top software development priority for the coming year, according to a Red Hat analysis released in 2021.

Although the adoption of container technology is becoming popular, when it comes to choosing the platform, companies often struggle to decide which platform to use. Both OpenShift and Docker are capable of providing efficient services.

So to help you determine what is ideal for your organization, see below to explore the distinctions between OpenShift and Docker:

OpenShift vs. Docker: Wallet

Red Hat OpenShift is a containerized Kubernetes platform that provides developers with a wide range of tools and features to minimize developer hurdles during the development phase. They can use the admin interface to monitor container resources and health, manage users, and interact with operators.

OpenShift can be deployed across cloud and infrastructure boundaries and is used as a platform as a service (PaaS). OpenShift also reduces the operational complexity of managing self-managed Kubernetes (K8s) clusters. Developers can request project resources through a web interface using the PaaS methodology, and CI/CD approaches and workflows dramatically shorten delivery times. OpenShift also restricts user access to certain regions of the system, due to its built-in security controls, end-to-end authorization, and authentication.

Docker is a core container technology that builds portable, self-contained application containers that can run in the cloud or on local hardware. Docker is platform independent, so it can easily deploy and run on any platform. And it offers a simplified user interface, so Docker is less complex and easy to learn for beginners.

Docker offers several tools: among which Docker includes Docker Engine, with container virtualization capabilities; Docker Compose, which allows orchestration of multiple containers; and Docker Swarm, which allows the management of container clusters on different networks. Developers can easily perform software development and testing tasks using these tools.

OpenShift vs. Docker: Partners

With a wide range of leading companies, Red Hat OpenShift has developed strong relationships to create flexible and reliable infrastructures. Red Hat offers developers and organizations two types of partner programs, Red Hat Ecosystem Catalog and Red Hat Marketplace, that allow them to build and use well-known OpenShift container solutions.

To build solutions that solve complex problems in minutes, Docker also counts several well-known industry IT leaders as partners. Alliance Partners, Channel Partners, and Docker Verified Publisher (DVP) Extension Partners are some of the types of partners offered by Docker.

OpenShift vs. Docker: use cases

OpenShift

Cisco

Cisco was struggling to engage its staff of more than 1,000 people in software development. The company needed to find a reliable solution to manage the large team of developers and quickly build products that met customer needs. As a result, Cisco relied on OpenShift to design and build the Lightweight Application Environment (LAE). The LAE is equipped with a multitude of tools that will allow developers to create and test the application. Processes that would normally take up to three months to complete were accomplished in minutes and with one-click manual interaction, thanks to the LAE.

Lenovo

Lenovo sought to rapidly transform its IT services from a traditional environment to a cloud environment to meet business expectations. However, the migration of outdated systems took longer than expected and they faced several obstacles and the inconvenience of periodic updates. Lenovo used OpenShift to simplify, which improved overall automation and DevOps collaboration for increased productivity.

BMW

BMW relied on DXC Technology to produce efficient technology to develop a platform where BMW could effortlessly deploy and monitor development processes when they were struggling to produce smart technology for their vehicle lineup. A Kubernetes-based platform with automation and deep learning (DL) features was created by DXC Technology and based on OpenShift. This allowed BMW to quickly and automatically manage the procedures associated with application development.

Docker

Alibaba Cloud

Due to its pricing options, Alibaba Cloud is frequently chosen by startups and micro businesses to develop their websites. Many e-commerce sites use Alibaba Cloud. Hence, the platform relied on Docker technology to execute the operations quickly and smoothly. Alibaba was able to quickly perform many actions on a particular website while running as many containers as needed, thanks to Docker.

Wiley Educational Services

Many colleges and universities use virtual learning services offered by Wiley Education Services (WES). The company wanted to expand its services and build relationships with new education partners, which meant it needed to work with efficient technology to design and publish the website faster. To achieve this, Wiley used Docker to quickly develop, test, and release containers using Docker at a fair price.

Development

Before the final deployment, the development process of each application faces many challenges. Some features may need to be changed and development teams may need to update the application architecture. Without the proper technology, it takes time and resources. You can quickly get around this problem by using Docker to separate different computing environments and run many instances of the app layers on different tenants. This usually time-consuming procedure can usually be sped up using Docker.

OpenShift vs Docker: User Reviews

When it comes to container technology, OpenShift and Docker are both widely adopted options, although Docker seems to have slightly more favorable reviews than OpenShift. While Docker is a fundamental tool for building new containers, OpenShift is an alternative for developers, due to its industry-grade technology and capabilities. Since OpenShift is also partly based on Docker, more and more companies are choosing Docker to build efficient container technology.

OpenShift vs. Docker: Overall

Docker and OpenShift container management and orchestration solutions are well known. They both have distinct benefits and features that make them ideal selections depending on your needs.

Docker is the preferred choice for developing, maintaining, and deploying containerized applications. Docker’s easy-to-use graphical user interface (GUI) is another factor why most organizations use it.

Additionally, Docker has a dedicated and enthusiastic community and expert support, making it easy to find answers to various issues. The best option for lone developers is Docker as its services come in free and budget options.

Although OpenShift offers a more sophisticated feature set, specific development teams may find this platform too complicated to use, especially startups and solo developers. Also, installing RedHat OpenShift is more complicated and not all container images from public registries can be used due to higher security rules.
