Deploy reliable, available critical production services in a high availability cluster

In the Red Hat High Availability Clustering (RH436) course, you will learn how to provide highly available network services to a mission-critical enterprise environment through the deployment and management of shared storage and server clusters. Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities.

You will set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services such as web servers and databases on that cluster. Cluster storage components from the Resilient Storage Add-On are also covered; installations and applications that require multiple cluster nodes can access the same storage simultaneously. This includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.

This course is based on Red Hat Enterprise Linux 8.3.

What You'll Learn

Impact on the organization

High availability clustering can improve reliability, availability, and resiliency of your mission-critical services, resulting in reduced downtime and easier hardware maintenance.

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 be able to create, manage, and troubleshoot highly available network services and tightly-coupled cluster storage for business-critical applications.

Students should be able to demonstrate the following skills:

  • Improve application uptime by using high availability clustering.
  • Manage storage in an high availability environment using iSCSI initiators, HA-LVM or LVM Shared Volume Groups as appropriate, and GFS2 cluster file systems.
  • Implement strategies to identify and eliminate single points of failure in high availability clusters.

Who Should Attend

Senior Linux system administrators who use high-availability clustering and fault-tolerant shared storage technologies to maximize resiliency of production services.

Frequently Asked Questions (FAQs)

  • Why get Red Hat certified?

    Red Hat certifications are highly respected in the IT industry and validate your expertise in open source technologies, particularly Red Hat Enterprise Linux (RHEL) and Red Hat OpenShift.

    These certifications demonstrate your ability to design, deploy, and manage complex enterprise environments using Red Hat solutions, increasing your value to employers and opening doors to a wide range of career opportunities.

  • What to expect for the examination?

    Red Hat certification exams are performance-based, meaning you'll be evaluated on your ability to perform real-world tasks in a live environment.

    This ensures that you not only understand the theoretical concepts but also have the practical skills to apply them.

    Note: Certification requirements and policies may be updated by Red Hat from time to time. We apologize for any discrepancies; do get in touch with us if you have any questions.

  • How long is Red Hat certification valid for?

    Red Hat certifications are current for three years.

    According to Red Hat, these certifications do not “expire”, or become “terminated” or “invalid”, but they can become “non-current”.

    There are different ways to keep a certification current, depending on the type of certification. You always have the option of retaking an exam to renew its associated certification.

    In some instances, you can earn other certifications to keep your certification current. This approach allows IT professionals to expand their skills and knowledge into new areas, which is increasingly important for a successful IT career.
