Linux High Availability Cluster Management from Pluralsight

Need to know how to improve the performance and reliability of your local or cloud Linux deployments? Discover the magic of high availability cluster computing.

Running server operations using clusters of either physical or virtual computers is all about improving performance over and above what you could expect from a single, high-powered server. But "improving performance" can mean different things in different contexts. This course, Linux High Availability Cluster Management, will bring many aspects of performance improvement to light. You'll be introduced to the principles of Linux-based HA and cluster management and the key tools currently in use in real-world environments - including Linux Virtual Server (LVS), HAProxy, Pacemaker, DRBD, OCFS2, and GFS2. You'll learn how to intelligently spread workloads among diverse geographic and demand environments (load balancing). You'll also discover how to provide backup servers that can be quickly brought into service in the event a working node fails (failover). Finally, you'll also learn about optimizing the way your data tier is deployed, or allowing for fault tolerance through loosely coupled architectures. By the end of this course, you will be able to improve and manage many aspects of the performance of your local or cloud Linux deployments, and they'll be more reliable for it.

Reviews summary

Linux ha cluster management: practical skills

According to learners, this course provides a strong foundation and practical skills in Linux High Availability cluster management. Students particularly appreciate the hands-on labs and clear explanations from the instructor, which make complex topics like Pacemaker and DRBD understandable and applicable to real-world scenarios. While it covers a comprehensive range of tools, some learners with less prior experience found it assumes a certain level of existing Linux knowledge. Additionally, a few reviews note that certain examples or lab setups may be outdated, suggesting potential areas for course updates.

Covers many topics but lacks deep dives in certain areas.

"The course content is decent, but it felt a bit like a whirlwind tour rather than a deep dive."

"It's a decent theoretical foundation, but don't expect to become an expert practitioner just from this course."

"The course attempts to cover too much, resulting in superficial explanations for many critical topics."

"The segment on specific cloud management tools was too brief to be truly useful. I'll need to explore more advanced topics elsewhere."

Instructor effectively explains complex technical topics.

"The instructor breaks down complex topics like Pacemaker and DRBD into understandable modules."

"Everything is explained clearly, and the progression from basic concepts to advanced configurations is logical."

"The instructor's explanations are quite thorough, and the demonstrations are helpful."

"The explanation of Pacemaker was the clearest I've encountered."

Hands-on labs and real-world scenarios reinforce learning.

"The hands-on labs were invaluable, truly reinforcing the concepts. I particularly appreciated the focus on real-world scenarios."

"The practical exercises using virtual machines really cemented my understanding of load balancing with HAProxy."

"The blend of theory and hands-on practice is perfect. I learned practical skills that are directly applicable to my job."

"I felt fully equipped to tackle HA challenges after completing this, thanks to the practical demonstrations."

Some course content and labs use older software versions.

"A few minor details in the older sections could use a refresh. Overall, the material is generally up-to-date."

"I found some of the examples outdated, especially regarding specific Linux distribution versions or tool configurations."

"The reliance on specific older software versions in some labs made it tricky to follow along on a modern system."

"Some of the older content feels a bit stale. My main critique is that older lab setups could benefit from an update to current distributions."

Learners may need substantial prior Linux experience.

"It assumes a very high level of prior knowledge, which isn't explicitly stated. I felt lost quickly."

"I found myself struggling with certain labs due to insufficient preliminary setup guidance."

"Not suitable if you don't already have significant experience, as the explanations often lacked the necessary detail for beginners."

"Prerequisites were not sufficiently highlighted, leading to a frustrating experience for me without extensive background."
