What is OpenShift ❓

OpenShift is a cloud development Platform as a Service (PaaS) hosted by Red Hat. It’s an open source cloud-based user-friendly platform used to create, test, and run applications, and finally deploy them on cloud.

OpenShift is capable of managing applications written in different languages, such as Node.js, Ruby, Python, Perl, and Java. One of the key features of OpenShift is it is extensible, which helps the users support the application written in other languages.

OpenShift comes with various concepts of virtualization as its abstraction layer. The underlying concept behind OpenShift is based on virtualization.

OpenShift supports a very large variety of applications, which can be easily developed and deployed on OpenShift cloud platform. OpenShift basically supports three kinds of platforms for the developers and users

  1. Infrastructure as a Service (IaaS)

2. Software as a Service (SaaS)

3. Platform as a Service (PaaS)

Why Use OpenShift?

OpenShift provides a common platform for enterprise units to host their applications on cloud without worrying about the underlying operating system. This makes it very easy to use, develop, and deploy applications on cloud. One of the key features is, it provides managed hardware and network resources for all kinds of development and testing. With OpenShift, PaaS developer has the freedom to design their required environment with specifications.

OpenShift provides different kind of service level agreement when it comes to service plans.

Free − This plan is limited to three years with 1GB space for each.

Bronze − This plan includes 3 years and expands up to 16 years with 1GB space per year.

Sliver − This is 16-year plan of bronze, however, has a storage capacity of 6GB with no additional cost.

Other than the above features, OpenShift also offers on-premises version known as OpenShift Enterprise. In OpenShift, developers have the leverage to design scalable and non-scalable applications and these designs are implemented using HAproxy servers.

Features

There are multiple features supported by OpenShift. Few of them are −

  • Multiple Language Support
  • Multiple Database Support
  • Extensible Cartridge System
  • Source Code Version Management
  • One-Click Deployment
  • Multi Environment Support
  • Standardized Developers’ workflow
  • Dependency and Build Management
  • Automatic Application Scaling
  • Responsive Web Console
  • Rich Command-line Toolset
  • Remote SSH Login to Applications
  • Rest API Support
  • Self-service On Demand Application Stack
  • Built-in Database Services
  • Continuous Integration and Release Management
  • IDE Integration
  • Remote Debugging of Applications

OPENSHIFT VERSIONS

OpenShift came into existence from its base named OpenShift V2, which was mainly based on the concept of gear and cartridges, where each component has its specifications starting from machine creation till application deployment, right from building to deploying the application.

Cartridges − They were the focal point of building a new application starting from the type of application the environment requires to run them and all the dependencies satisfied in this section.

Gear − It can be defined as the bear metal machine or server with certain specifications regarding the resources, memory, and CPU. They were considered as a fundamental unit for running an application.

Application − These simply refer to the application or any integration application that will get deployed and run on OpenShift environment.

As we go deeper in the section, we will discuss on different formats and offerings of OpenShift. In the earlier days, OpenShift had three major versions.

OpenShift Origin − This was the community addition or open source version of OpenShift. It was also known as upstream project for other two versions.

OpenShift Online − It is a pubic PaaS as a service hosted on AWS.

OpenShift Enterprise − is the hardened version of OpenShift with ISV and vendor licenses.

WHAT’S INCLUDED

Container host and runtime

Red Hat OpenShift ships with Red Hat® Enterprise Linux® CoreOS for the Kubernetes master, and supports Red Hat Enterprise Linux for worker nodes. Red Hat OpenShift supports standard Docker and CRI-O runtimes.

Enterprise Kubernetes

Red Hat OpenShift includes hundreds of fixes to defect, security, and performance issues for upstream Kubernetes in every release. It is tested with dozens of technologies and is a robust tightly-integrated platform supported over a 9-year lifecycle.

Validated integrations

Red Hat OpenShift includes software-defined networking and validates additional common networking solutions. Red Hat OpenShift also validates numerous storage and third-party plug-ins for every release.

Integrated container registry

Red Hat OpenShift ships with an integrated, private container registry (installed as part of the Kubernetes cluster or as standalone for greater flexibility). Teams with greater requirements can also use Red Hat Quay.

Developer workflows

Red Hat OpenShift includes streamlined workflows to help teams get to production faster, including built-in Jenkins pipelines and our source-to-image technology to go straight from application code to container. It is also extensible to new frameworks like Istio and Knative.

Easy access to services

Red Hat OpenShift helps administrators and support application teams, with service brokers (including direct access to AWS services), validated third-party solutions, and Kubernetes operators through the embedded OperatorHub.

OpenShift — Architecture

OpenShift is a layered system wherein each layer is tightly bound with the other layer using Kubernetes and Docker cluster. The architecture of OpenShift is designed in such a way that it can support and manage Docker containers, which are hosted on top of all the layers using Kubernetes. Unlike the earlier version of OpenShift V2, the new version of OpenShift V3 supports containerized infrastructure. In this model, Docker helps in creation of lightweight Linux-based containers and Kubernetes supports the task of orchestrating and managing containers on multiple hosts.

Benefits

Improved productivity with standardized development environment and self-service provisioningEnhanced security with enterprise technology from Red Hat and continuous monitoring provided by SysdigSignificantly reduced hardware costs by running OpenShift on bare metal

Performance and security improvements help Ford deliver services and work with partners more efficiently

Significantly increased developer productivity

Using OpenShift Container Platform, Ford has accelerated time to market by centralizing and standardizing its application development environment and compliance analysis for a consistent multicloud experience. For example, OpenShift’s automation capabilities help Ford deploy new clusters more rapidly.These improvements are enhanced by the company’s shift from a traditional, waterfall approach to iterative DevOps processes and a continuous integration and delivery (CI/CD) workflow.Now, some of the same processes for stateful workloads take minutes instead of months, and developers no longer need to focus on underlying infrastructure with self-service provisioning. These improvements extend to Ford’s IT hosting, where the company has seen a significant productivity improvement for CaaS support. Dealers and plant operators gain access to new features, fixes, and updates faster through Ford’s multitenant OpenShift environment.“With OpenShift, we have a common framework that can be reused for deploying applications or services within our datacenter or to any major cloud provider,” said Presnell. “We can now deliver features in a more secure, reliable manner.”

Enhanced security and compliance with enterprise container and monitoring technology

Companies in the automotive industry must comply with various security standards and regulations, such as Payment Card Industry Data Security Standard (PCI DSS) and personal data protection standards. When creating its new container platform, Ford sought to balance providing access to partners and developers with ensuring vulnerabilities and updates were addressed and working toward future adoption of a DevSecOps approach.“In a container environment, moving applications and code continuously, security needs to be automated and built in from when a container is created,” said Payal Chakravarty, Vice President, Products, Sysdig. “Sysdig provides real-time vulnerability management in CI/CD pipelines. Security checks are in place to analyze code and identify issues before production.”To support this approach, Ford standardized on Red Hat container images and registries using Red Hat Quay. OpenShift provides a unified management interface across Ford’s entire infrastructure, as well as built-in Security Enhanced Linux (SELinux) capabilities.Sysdig Secure and Sysdig Monitor help Ford enhance this protection with improved, data-based insight into container infrastructure to run OpenShift in a compliant way. “Sysdig can tell us about a container’s network activity, can help us protect multiple containers running on a single host, and provide continuous monitoring and alerts,” said Puranam.

Significantly reduced hardware costs

Shifting to a container-based approach requires less initial hardware investment — and ongoing savings as Ford continues to modernize and migrate its legacy applications. The company has improved the efficiency of its hardware footprint by running OpenShift on bare metal and using its existing hardware more effectively.“We were able to initially run OpenShift on a fleet of hardware that had literally been pulled out of our datacenter to be scrapped. We put that hardware back and are successfully running production OpenShift on it today,” said Puranam.By establishing an approach for controlling costs and increasing profit margins, Ford can reallocate resources to higher-value projects to address new business opportunities faster.

Successful adoption of OpenShift and DevOps creates foundation for new opportunities to innovate

Ford is already experiencing significant growth in demand for its OpenShift-based applications and services. It aims to achieve migration of most of its on-premise, legacy deployments within the next few years.The company is also looking for ways to use its container platform environment to address opportunities like big data, mobility, machine learning, and AI to continue delivering high-quality, timely services to its customers worldwide.“Kubernetes and OpenShift have really forced us to think differently about our problems, because we can’t solve new business challenges with traditional approaches. Innovation and constantly exploring and questioning are the only way we can move forward,” said Puranam. “It’s a journey, but one that we have a good start on. Thanks to having the right set of partners, with both Red Hat and Sysdig, we’re well-situated for future success.”
