Though much has been written about containerization, many businesses still struggle with best practices and adoption. Here’s a brief introduction to the containerisation and my experience on resolving the challenges of moving to OpenShift 4.
Containers help businesses take advantage of cloud infrastructure and meet the needs of cloud-native applications. In fact, containerization and the public cloud are transformation tools to accelerate the pace of software development, iteration and innovation.
Why do you need to move from OpenShift 3 to OpenShift 4?
Red Hat OpenShift is a leading Kubernetes platform that helps enterprises streamline workflows and run business applications regardless of their infrastructure. OpenShift container platforms enable development teams by increasing the frequency of delivering new applications and features essentially reducing the time that is required to manage IT environments. This allows businesses to deliver higher quality service across disparate locations.
One of the main challenges with OpenShift 3 is that the infrastructure is configured manually before the actual deployment. Because of this, consistent installation and upgrades to platforms are a challenge for most enterprises. This in turn brings more challenges, such as the burden of configuring the provider infrastructure and installing the RHEL OS separate from the OpenShift Kubernetes installation. In short, this creates a new set of challenges for the platform administrator and if the infrastructure is incompatible with the Kubernetes platform layer can create issues during upgrades of the OpenShift platform.
These challenges aren’t unique to OpenShift – they are present in all Kubernetes platforms, especially DIY kubernetes platforms, which has driven both Red Hat and the broader Kubernetes community to explore new innovations to address them. With this in mind, Red Hat set out to deliver a better full-stack install and upgrade experience with OpenShift 4. The focus of OpenShift 3 had been on delivering a trusted Kubernetes solution and container platform. OpenShift 4 addresses the challenges businesses face when installing the platform and keeping it updated with the latest security patches and Kubernetes releases.
The benefits of OpenShift 4
OpenShift 4 aims to deliver a cloud-like or managed Kubernetes experience across all major cloud and on-prem providers. The OpenShift 4 console allows for better management and tracking of microservices deployments. Instead of managing how the microservices communicate, developers can focus on building the business logic around the communication. In addition, the software can leverage the tracing and visualisation capabilities to debug issues when they arise.
Designed to simplify the process of managing distributed services, OpenShift 4 empowers developer innovation. The goal is both to simplify the initial installation, but also to leverage full-stack automation and upgrade management. OpenShift 4 is changing the way enterprise Kubernetes are delivered through automation, providing the best of both worlds – developer-friendly Kubernetes distribution and the immutable and automated operations of Tectonic.
