Your Guide to Navigate Red Hat Open Stack in 2022
Background
Today’s ever-changing market conditions demand businesses to be agile to meet the needs of customers and market conditions. For the technical professionals of any organization, this means having to push new services out faster. But, in order to do so, they also require an IT infrastructure that is equally agile, scalable, cost-effective, consistent, and fast, and Red Hat OpenStack could be your answer to this.
Red Hat OpenStack?
OpenStack is a collection of open-source projects that allows users to build and manage private and public clouds. The OpenStack platform is composed of tools called ‘projects’ which controls pools compute, storage, and networking resources, identity and image services throughout a datacenter through a dashboard. Red Hat OpenStack platform bands together with an open, community-driven innovation which in turn harnesses the maximum potential of individuals and organizations to deliver new and innovative applications and services, propelling their business forward.
The pairing of the cloud infrastructure along with the Red Hat OpenStack Platform provides for a solid foundation to traverse through the critical workloads and pave the way forward for hybrid cloud, the edge and beyond.
In virtualization, resources such as storage, CPU, and RAM are abstracted from a variety of vendor-specific programs and split by a hypervisor before being distributed as needed. OpenStack uses a consistent set of application programming interfaces (APIs) to abstract those virtual resources 1 step further into discrete pools used to power standard cloud computing tools that administrators and users interact with directly.
So, is OpenStack just a virtualization management platform?
Not quite. There are a lot of similarities, but they’re not the same.
Yes, OpenStack and virtualization management platforms both sit on top of virtualized resources and can discover, report, and automate processes in vendor-disparate environments.
But while virtualization management platforms make it easier to manipulate the features and functions of virtual resources, OpenStack actually uses the virtual resources to run a combination of tools. These tools create a cloud environment that meets the National Institute of Standards and Technology’s 5 criteria of cloud computing: a network, pooled resources, a user interface, provisioning capabilities, and automatic resource control/allocation.
How does OpenStack work?
OpenStack is essentially a series of commands known as scripts. Those scripts are bundled into packages called projects that relay tasks that create cloud environments. In order to create those environments, OpenStack relies on 2 other types of software:
- Virtualization that creates a layer of virtual resources abstracted from hardware
- A base operating system (OS) that carries out commands given by OpenStack scripts
Think about it like this: OpenStack itself doesn’t virtualize resources, but rather uses them to build clouds. OpenStack also doesn’t execute commands, but rather relays them to the base OS. All 3 technologies—OpenStack, virtualization, and the base OS—must work together. That interdependency is why so many OpenStack clouds are deployed using Linux®, which was the inspiration behind RackSpace and NASA’s decision to release OpenStack as open source software.
What are the benefits of Red Hat OpenStack?
There is a demand for reliable cloud foundations providing essential elements like top-notch security features, operators, and administrators that are able to manage the adoption of OpenStack technology. Red Hat’s training and certification are designed to help accelerate your career by helping you grow your OpenStack knowledge.
