Overview Of OpenShift

OpenShift, a Platform as a Service (PaaS) by Red Hat needs no introduction. Available on GitHub, OpenShift offers self-service and on-demand application stacks, allowing developers to create applications with a language of choice.

Java Open Shift

OpenShift allows easy deployment and execution of Java applications using various application servers and frameworks. Java applications can be deployed easily using OpenShift using various environments, more so as Java is designed to have a very few implementation dependencies.

  • JBoss AS
  • Wildfly
  • Apache Tomcat (JBossEWS)
  • JBoss EAP
  • Vert.x
  • JBoss xPaaS Services

Features Of OpenShift

The rich feature set offered by OpenShift makes it a very popular platform in the Java Developer community today.

  • Offers A Variety Of Languages

The best part about the OpenShift platform is, it allows the developers to choose the correct method for the given work and providing various choices for every project, as per the requirement. This way developer can code the applications in the language of his choice, be it Java, Ruby, Node.js, Python, PHP or any other.

  • Databases

With OpenShift, gives access to private database instances with full control. One can have a choice between the classic relational database and modern NoSQL data stores, like MySQL, PostgreSQL, MongoDB, and SQLite.

  • Extensible Cartridge System

Along with the built-in languages and services, developers can add any other language, database or middleware components required for their projects, via the OpenShift Cartridge API.

  • Quickstart Templates

OpenShift provides templates with pre-developed codes, which help the developer start work with their required application framework, almost instantly. Developers can find and deploy their favorite languages, frameworks, and database with just one click.

  • Source Code Version Management

OpenShift comes with the Git distributed version control and source code management system. The developers use SSH secured Git protocol to check code into the secure Git repository residing within their application container with OpenShift. Git gives fast, secure and controlled management of application source code versioning.

  • Single Click Deploy

OpenShift platform deployment is as easy, as clicking a button or entering a “Git push” command. Designed to eradicate numerous problems handled by System Administration, related to application provisioning and deployment, OpenShift also allows control over the total deployment lifecycle automatically.

  • Multiple Environment Support

Since the OpenShift platform supports Development Lifecycle stage environments, such as Dev, QA, Pre-Prod, and Prod, for multiple Applications, the Enterprise can easily approve and implement the PaaS platform without making any major changes in their methodologies or processes.

  • Hosting Regions

With OpenShift Online, one can create applications in different regions. That way developers can manage applications through many distinct demographics by controlling deployments between groups of servers. Developers can increase the performance of the application with very efforts by deploying the applications in geography closer to the expected clients.

  • Standardized Developer Workflows

If OpenShift is used as the Cloud application platform, the application development organization can regulate the workflow for the developer creating the reusable processes for application delivery to manage the entire process.

  • Backup, Restore & Clone With Snapshots

For backup and restore of the applications, Application snapshots are used. Snapshots are contained in tar.gz files, which contain the application and all local files, including log files.

  • Continuous Integration And Release Management

Jenkins is used for continuous integration and automatic release management in the OpenShift platform. Jenkins is used to test code check-in, organize the build process and also to promote or cancel or release an application based on the results of the tests.

  • Dependency And Build Management

The OpenShift platform provides Dependency and Build Management for many popular programming languages, such as Composer and PEAR for PHP, Bundler for Ruby, NPM for Node.JS, and Maven for Java. They help the developer to automate the process to identify dependencies of source code, getting the required libraries, and building the also developing the complete application. This increases productivity and helps to reduce the chances of error.

  • Automatic Application Scaling

With automating horizontal application scaling, the OpenShift platform allows cloud elasticity, because with reduced manual operation, the number of application instances increases.

  • System Component Redundancy

The architecture of the Openshift platform has a stateless control plane (Brokers), a messaging infrastructure, and application hosting infrastructure (Nodes). Each part of which can be constructed with multiple redundancies for scenarios such as fail-over and load balancing. This reduces the impact of hardware or infrastructure failure.

  • Collaboration

Application development can collaborate with domain membership. Multiple developers can be teamed up as a part of roles that run alongside within the same domain, known as a team. One team is counted as one member for a domain, having same permissions that is given to a standard domain member.

  • Responsive Web Console

Since the OpenShift platform also has a rich web console Developer interface, it can be used to easily view responsive UI designs on various devices be it mobile smartphones or laptop or desktop workstations. With access to the web console, developers can create, modify and manage the application within the web console.

  • Rich Command-line Tool Set

Along with a rich IDE, the Openshift platform includes a set of command-line tools that provide total access to the developer interface of the Paas, these tools are especially for those who prefer to work from the Command-Line.

They are easy to use and are scripted for automated interactions.

  • Integrated Development Environment

The OpenShift platform has built-in integration with Eclipse, JBoss Developer Studio, and Titanium Studio. This helps many developers to stay within the IDE they prefer to work with while working with OpenShift.

  • JBoss Middleware

The OpenShift platform has the powerful cloud-based services of JBoss Middleware, which helps developers with building applications, integrating with other systems, managing the application using rules and processes and finally deploying the application across the hybrid environment.

  • Marketplace Add-Ons

The marketplace add-ons provide users of OpenShift Online with self-service and on-demand add-on services. Add-ons could be for application services or DevOps services.

Application Services are used with data persistence, search, caching, messaging, and other such areas, whereas DevOps services are used with software lifecycle capabilities like continuous integration and load testing.

Looking Ahead

Since Cloud is the buzzword today and robust Cloud-based platforms are in demand, OpenShift with its salient features attracts Enterprises to itself. Furthermore, because it can be used in conjunction with widely accepted languages like Java, its popularity is steadily increasing.
