What is OpenShift?
Who uses OpenShift?
Why developers like OpenShift?
Here are some stack decisions, common use cases and reviews by companies and developers who chose OpenShift in their tech stack.
How Uber developed the open source, end-to-end distributed tracing Jaeger , now a CNCF project:
Distributed tracing is quickly becoming a must-have component in the tools that organizations use to monitor their complex, microservice-based architectures. At Uber, our open source distributed tracing system Jaeger saw large-scale internal adoption throughout 2016, integrated into hundreds of microservices and now recording thousands of traces every second.
Here is the story of how we got here, from investigating off-the-shelf solutions like Zipkin, to why we switched from pull to push architecture, and how distributed tracing will continue to evolve:
We use Kubernetes because we decided to migrate to a hosted cluster (not AWS) and still be able to scale our clusters up and down depending on load. By wrapping it with OpenShift we are now able to easily adapt to demand but also able to separate concerns into separate Pods depending on use-cases we have.
Heroku vs OpenShift. I've never decided which one is better. Heroku is easier to configure. Openshift provide a better machine for free. Heroku has many addons for free. I've chosen Heroku because of easy initial set-up. I had deployment based on git push. I also tried direct deployment of jar file. Currently Heroku runs my Docker image. Heroku has very good documentation like for beginners. So if you want to start with something, let's follow Heroku. On the other hand OpenShift seems like a PRO tool supported by @RedHat.
We use Docker for our #DeploymentWorkflow along with OpenShift SonarQube Sonatype Nexus GitLab Vault Apache Maven AngularJS Spring-Boot
SG-TravelBuddy server application is hosted on Red Hat OpenShift Online (v3). SG-TravelBuddy mobile (Android) app is connecting to this server for data operations. OpenShift
We use OpenShift because it's easy to manage a cluster of servers even with a small team and it's cheaper to operate than AWS.
- Built-in support for Node.js, Ruby, Python, PHP, Perl, and Java (the standard in today's Enterprise)
- OpenShift is extensible with a customizable cartridge functionality that allows developers to add any other language they wish. We've seen everything from Clojure to Cobol running on OpenShift.
- OpenShift supports frameworks ranging from Spring, to Rails, to Play
- Autoscaling- OpenShift can scale your application by adding additional instances of your application and enabling clustering. Alternatively, you can manually scale the amount of resources with which your application is deployed when needed.
- OpenShift by Red Hat is built on open-source technologies (Red Hat Enterprise Linux- RHEL).
- One Click Deployment- Deploying to the OpenShift platform is as easy a clicking a button or entering a "Git push" command.
