OpenShift is a family of containerization software products developed by RedHat. Its flagship product is the OpenShift Container Platform — an on-premises as a services built around Docker Container orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux. The family’s other products provide this platform through different environments: OKD serves as the community-driven upstream(akin to the way that Fedora is upstream of Red Hat Enterprise Linux), OpenShift Online is the platform offered as Software as a Service, and Openshift Dedicated is the platform offered as a managed service.
Features and benefits
- Manage with simplicity. In the cloud or anywhere : Red Hat OpenShift offers automated installation, upgrades, and lifecycle management throughout the container stack — the operating system, Kubernetes and cluster services, and applications — on any cloud.
- Build fast, Ship first, Deploy everywhere : Red Hat OpenShift helps teams build with speed, agility, confidence, and choice. Code in production mode anywhere you choose to build. Get back to doing work that matters.
- Build with Kubernetes, Trust with Red Hat : Red Hat OpenShift is focused on security at every level of the container stack and throughout the application lifecycle. It includes long-term, enterprise support from one of the leading Kubernetes contributors and open source software companies.
CASE STUDY: HAVAN
Brazilian retailer cuts app delivery time with Red Hat OpenShift
Havan, a Brazilian department store chain, needed to enhance its existing application development environment to support continuing business growth. By adopting a modern, container-based infrastructure using Red Hat OpenShift, the retailer has reduced delivery times from weeks to days, improved its code quality, and gained an advantage in recruiting and retaining skilled IT talent.
- Cut application delivery time from 6 weeks to less than 3 days
- Reduced development time and costs with better code quality and hardware use
- Improved IT talent recruitment by adopting modern architecture and technology
Modernizing infrastructure to support retail business growth
In business for 34 years, Havan is a Brazilian department store brand with 123 locations across 17 of the country’s states. The retailer projects revenue of R$10 billion in 2020 and is currently focusing investment on expanding to 200 locations by 2022.
Havan supported its growing operations with a traditional Microsoft Windows and SQL Server architecture running in its datacenter. Development of all applications — from purchasing and logistics to online and in-store sales — was completed by an internal team of 200 people, called Havan Labs. However, manual processes meant publishing a new version was time-consuming and prone to failures.
While the retailer had adopted some modern approaches, such as DevOps and continuous integration and delivery (CI/CD), incomplete integration between platforms delayed delivery of bug fixes and new features to enhance Havan’s customer experience..
To speed the development process and keep pace with growth, Havan’s IT department began to search for newer technology that could offer greater agility. As a result of this search, the retailer sought a Kubernetes container platform that could run on-premise with its datacenter hardware and software.
Supporting DevOps approach with enterprise container technology from Red Hat
After working with local Red Hat partner Service IT on a successful proof of concept (POC), Havan decided to adopt Red Hat OpenShift as the new foundation of its development environment. The retailer had evaluated Microsoft Azure and Amazon Web Services (AWS) but sought an on-premise solution, rather than one that would require cloud computing.
“Our development process was based on an old methodology,” said Varela. “We found that Red Hat OpenShift would assist us in adopting modern development best practices, including DevOps.”
Deployed and run by Service IT, Red Hat OpenShift is a Kubernetes-based platform that offers a complete application container environment to support the architecture, processes, and services Havan needs to support its development and operations teams.
In addition to ongoing assistance from Service IT, Havan works with a Red Hat Technical Account Manager (TAM), a highly skilled technical expert with extensive industry and Red Hat product knowledge, to support its new Red Hat OpenShift environment.
“The close relationship between Red Hat and Service IT, with dedicated staff working exclusively on this project, made it easier to get things done,” said Varela.
Speeding IT and services enhancements with flexible containers and efficient processes
Decreased application delivery time from weeks to days
Previously, creating an environment to publish an application required Havan’s developers to submit a request to the infrastructure team. The infrastructure team would then build a Windows environment, allocate servers, set up the production environment, and configure the development and certification environment — a process that took a week or longer.
Now, Havan’s IT teams can create and launch new applications and service updates faster with its new container-based development environment built with Red Hat OpenShift. The retailer’s developers can use self-service provisioning to create standardized yet customizable environments for their projects.
“Previously, it took about 6 weeks for an application to go live. Now, we can push them live in less than 3 days,” said Varela.
Improved code quality and resource use to save time and money
Changes to its infrastructure design has helped Havan reduce the number of bugs and errors in its production environment. The retailer has used Red Hat OpenShift to standardize development workflows for creating specific test, certification, and production environment configurations. Containers also help the company adapt to new market technology by isolating applications for greater stability across operating systems and framework versions. As a result, Havan’s teams can focus less on maintenance and bug fixes and more on valuable, end-user-facing work.
Additionally, switching to container technology and adopting new monitoring and telemetry capabilities has helped the retailer cost-effectively adapt its hardware footprint and resource use as it grows. With Red Hat OpenShift, Havan can more easily view application and cluster resource use, as well as application logs.
Enhanced talent recruitment and retention
Havan’s IT team purchased Red Hat Learning Subscription, an all-access subscription pass to all of Red Hat’s online learning courses, video classroom courses, and course materials, as well as lab time and short courses taught by field experts. With this training access, Havan’s teams could build their expertise and skills on Red Hat OpenShift, containers, and other related technology to confidently operate and manage the new development environment, improving talent retention by investing in professional development.
In addition, to optimize compatibility with Red Hat OpenShift and leading container technology, Havan’s developers have shifted their work from Microsoft’s .NET Framework to .NET Core, an open source, cross-platform version that works across Windows and Linux operating systems. This transition to a more flexible, agile framework and modern container technology is an example of a shift that will help the retailer recruit qualified developer talent.
After establishing its new container-based development environment, Havan plans to continue working with Red Hat to transition more applications from its Windows .NET Framework environment to Red Hat OpenShift and .NET Core and quickly adopt new features from Microsoft’s ongoing enhancements of the framework.
