Ceph user communities are filled with stories about things breaking, not starting, or failing. Does this mean the technology is bad? Not at all. It signifies progress. Users encounter the technology's bottlenecks, discover solutions, and submit patches upstream. The more experience there is with the technology and the more users invest in it, the more documented problems and solutions will emerge. A similar situation was recently seen with Kubernetes.
Ceph has come a long way from the project by Sage Weil in his doctoral dissertation in 2007 to the acquisition of Weil's company Inktank by Red Hat in 2014. Today, many of Ceph's bottlenecks are already known, and numerous case studies from practitioners can be examined and noted.
On September 1, we will launch the beta-testing of our practical video course on Ceph. We will teach you how to work with the technology reliably and effectively.
We initially decided to test the hypothesis of how interesting the technology is and how eager the community is to understand it — and at the moment.
The earlier you join the course evaluation, the more impact you can have on
the final version of the course — and you can save money too. Your questions and difficulties with mastering Ceph will become part of the course — this way, you will gain the knowledge necessary for your work from those who have hands-on experience with the technology and work with it daily.
You can view the final program and discounts for beta testers on .
At the very beginning of the course, you will receive systematic knowledge on basic concepts and terms, and by the end, you will learn how to fully install, configure, and manage Ceph.
By September 1, the following topics will be ready:
— What is Ceph and what it is not?
— Overview of architecture;
— Integration of Ceph with popular Cloud Native solutions.
By October 1, you will receive:
— Installation of Ceph;
— Monitoring Ceph;
— Ceph performance. Performance mathematics.
By October 15:
— Everything else.
During the course, we will answer questions such as... Is it possible to run a database on Ceph under heavy load? What configurations are necessary? Can a network storage on Ceph be comparable in performance to a local disk? How to configure Ceph so that data integrity is ensured and node outages do not affect its operation? For which tasks is Ceph suitable, and which ones is it not? When can the Ceph technology be implemented? And many more.
Course Speaker:
Vitaly Filippov. Expert developer at CUSTIS, a Linux enthusiast, ‘cepher’. Works with React, Node.js, PHP, Go, Python, Perl, Java, C++, involved in infrastructure tasks. Tested and researched Ceph code, submitted patches upstream. Has deep knowledge of Ceph performance, author of the Wiki article “».
Other practical speakers will join as the course progresses.
By October 15, participants will receive a practically tailored course on Ceph that addresses their needs, issues, and questions.
