Using resource isolation to achieve multitenancy with Red Hat OpenShift
By IBM Developer
Software multitenancy refers to a software architecture where a single software instance serves multiple users or groups, also called tenants.
Red Hat® OpenShift® clusters are often used to host workloads from a single tenant or customer who owns the cluster. Alternatively, multiple workloads from different tenants could also be run in a single cluster. To achieve this, those workloads must be isolated from each other so that the tenants cannot interfere with one another.
Many cloud providers use multitenancy to optimize resource usage in a SaaS architecture. There are two common ways to achieve multitenancy.
- Resource isolation of CPU, memory, and similar resource.
- Network isolation limiting access between tenants.
🎓 What will you learn
Join us for an online workshop to learn how to achieve multitenancy using resource isolation in OpenShift. You'll also learn how to deploy a Java Liberty application on OpenShift using the ODO Command Line Interface (CLI).
- Creating projects and allocating resource quotas
- Deploy and run applications in OpenShift
- Improving application performance and response times
- Isolating resources for optimisation
- Hands-on experience with two scenarios
1. Performance of an application is affected by the resource utilization of another application in the same project without resource quotas applied.
2. Performance of an application is unaffected by the resource utilization of another application deployed in a different project and with resource quotas applied.
👩💻 Who should attend
- Developers, ITOps Engineers, and anyone interested in SaaS, multitenancy, Application Performance and Monitoring, and Red Hat OpenShift
