Impact on the organization
Businesses of all sizes have recognized the value of and embraced cloud computing, growing public cloud hosting and services to surpass legacy enterprise computing. Many large enterprises need private or hybrid infrastructures for issues of security, privacy, regulation, and compliance.
In the OpenStack world, Red Hat OpenStack Platform is recognized as the primary choice in supported open source private cloud infrastructure. OpenStack itself has reached a level of maturity for core services and, in the process, has distinguished itself as an incredibly flexible IaaS platform for many industries and models, including telecom, finance, service, ecommerce, education, healthcare, government, and aviation. Enterprises need hybrid and private solutions, not just public cloud services, and Red Hat OpenStack Platform specializes in private and hybrid clouds that can be highly customized according to business needs. Organizations can integrate services, hardware, and tools from multiple vendors into Red Hat OpenStack Platform, while quickly and easily deploying their cloud systems, introducing new services, and responding to changing market conditions.
Customer organizations will find this version to be easier to install and manage, yet capable of handling more diverse types of cloud and legacy workloads with an expanding portfolio of flexible resource configuration. Enhancements in Red Hat OpenStack Platform 13.0 address evolving customer requirements for more capable cloud infrastructures, including:
- Use of the popular Ansible toolset for installations, upgrades, and patching.
- Enhanced networking features and performance using Open Virtual Networking (OVN), an evolved networking framework based on Open vSwitch.
- Quicker application scaling with the newly designed load balancer built using efficient containers.
- Introduction of shared file system storage, including the new CephFS as a back end.
- Integration of hyperconverged technology that combines storage and compute resources on the same compute nodes for lower latency and higher performance.
- The ability to integrate the popular OpenShift application platform onto the Red Hat OpenStack infrastructure.
Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.
Impact on the individual
As a result of attending this course, you will know how to configure and manage an OpenStack installation featuring all of the common, core features and services used by enterprise private/hybrid cloud customers. You will also be able to choose and customize compute, storage, networking, deployment, and application support resources and services tailored to your enterprise needs.
Students should be able to demonstrate the following skills:
- Navigate and manage the control plane on the undercloud and the overcloud.
- Work with containerized overcloud infrastructure services.
- Manage necessary authentication, authorization, and security administration.
- Navigate and describe all network layers in an IaaS and all aspects of SDN design and management.
- Manage compute node and storage resource, including hyperconvergence.
- Troubleshoot typical OpenStack operations.
