FAQs

I see the difference between OpenStack vs OpenShift, but can they work together? If so, how?

Yes, OpenStack and OpenShift can definitely work together to create a more comprehensive cloud solution.  OpenStack provides the infrastructure layer (compute, storage, network) while OpenShift acts as a higher-level platform for managing containerized applications running on top of that infrastructure. A common use case is building a private cloud with OpenStack and then using OpenShift to orchestrate modern, cloud-native workloads within that environment.

I'm a developer focused on creating applications. Given that, should I care about OpenStack vs OpenShift, or is one much more relevant than the other?

Your primary focus would likely be on OpenShift. It’s built with developers in mind, providing tools for easy deployment, scaling, and management of containerized applications.  While understanding the underlying infrastructure matters, you won’t usually interact with OpenStack directly, whereas OpenShift offers features directly impacting your coding and building processes.

The article mentions OpenStack vs OpenShift in the context of hybrid cloud. Could you elaborate on how a hybrid cloud setup with these technologies might look?

One way to build a hybrid cloud with OpenStack and OpenShift is to deploy OpenStack as your private cloud infrastructure and then integrate it with a public cloud provider (like AWS or Azure).  OpenShift can then be deployed both on-premises and in the public cloud, providing a consistent platform for managing containerized applications across the entire hybrid environment.

Security is a concern for my organization. Do the differences between OpenStack vs OpenShift have any impact on security considerations?

Both OpenShift and OpenStack have security features, but the approach differs slightly. OpenShift security proactively safeguards containerized applications with integrated image scanning and container isolation. OpenStack offers security controls at the infrastructure level: firewalls, network segmentation, identity management, etc.  When planning your cloud environment, you’ll need to consider security at both these layers.

Could I gradually adopt these technologies? For example, start with OpenShift and later add OpenStack for more infrastructure control?

Absolutely!  This incremental approach is often a good strategy.  Many organizations start by deploying OpenShift to modernize their application development processes and to gain experience with containers.  Once they have a solid understanding of containerization, they might then expand by adding OpenStack to gain more granular control over their infrastructure and to potentially build a private or hybrid cloud environment.

What's the difference between OpenShift and OpenStack?

OpenStack and OpenShift are both open-source technologies used in cloud computing, but they serve different purposes. OpenStack is an Infrastructure-as-a-Service (IaaS) platform, providing a set of services for you to build and manage your own cloud infrastructure. Think of it as giving you the tools to create virtual machines, storage, and networking resources.  OpenShift, on the other hand, is a Platform-as-a-Service (PaaS) platform built on top of OpenStack (or other cloud platforms). It’s designed specifically for deploying and managing containerized applications and handles much of the automation involved, like scaling, security, and monitoring.

Is OpenStack owned by Red Hat?

While Red Hat offers a commercial distribution of OpenStack, OpenStack itself is an open-source project and not owned by any single company.
