Outcomes:

Impact on the organization

    This course is intended to develop the skills needed to utilize and manage the daily operation of a private cloud. A private cloud can reduce costs through fine-grained resource control, simplifying regulatory compliance, and permitting easier integration with legacy systems. Using the skills taught by this course, users and operators will be able to create and use project resources built of networks and services running running templated applications, in customizable and adaptable configurations, virtually eliminating the need to build physical systems for any new projects. This release brings major enhancements and stabilization, including service containerization, new installation and management tools, a newly designed application load balancing component, and a significant expansion of features supported by the OpenStack CLI. Also, clients can use various installation tools, most noticeably PackStack, which is completely deprecated.

  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 understand the architecture of a private or hybrid OpenStack cloud infrastructure and will be able to create, manage, and troubleshoot software-defined network services, resources, servers, and applications for dynamically scalable business environments.

You should also be able to demonstrate these skills:

  • Design and implement on-demand projects, software-defined networks, and virtual machine instances.

  • Deploy a proof-of-concept OpenStack installation for practice, development, demonstration, and testing, back in your own home or business computing environment.

  • Manage software-defined networks such as subnets, routers, floating IP addresses, images, flavors, security groups/rules, and block and object storage.

  • Create and customize advanced VM instances as applications, customize on deploy, and create scalable stacks of multiple VM applications.

Recommended next exam or course:

  • Choose to learn the OpenStack version that matches your company's infrastructure, either as currently built or as planned for upgrade in the near future.
    Red Hat strongly recommends pursuing the same Red Hat OpenStack Platform version when scheduling each course and exam in the OpenStack curriculum path. Red Hat OpenStack Administration II is based on OpenStack 10.0, but will also be available on OpenStack 13.0 soon, with the title of Red Hat OpenStack Administration II: Infrastructure Configuration for Cloud Administrators (CL210)

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.
