As a long time Software Engineer who moved into a DevOps Engineer role and now into an SRE role, Nana explained the differences of a DevOps Engineer and SRE very well. Good job!

[davismar]

I have worked both as a DevOps and SRE. Your explanation to both concepts and roles is on point. I personally prefer the DevOps role and I will be transitioning back to it. I enjoy more working in the Infrastructure as Code side, involved with CI/CD and Cloud tools. My Experience as an SRE was more related to monitoring and incident handling, which is sometimes a pain in the a**.

I am an SRE myself and the whole video is Spectacular way of explaining what SRE is. Great work!

[PrasannaVarshan]

I am an SRE and my pain portrayed as a poem in this video. #respect

[greggschofield]

Thank you Nana - After watching your videos as a software engineer for over two years I have just been offered my first job as a DevOps engineer at a startup. Many thanks!

[Successwithjs]

You have such a great way of explaining concepts like this.

I've worked as a "DevOps" since 2003 - back then I was just a "build manager" and more recently am SRE at a big retailer.

I don't think I really thought there was a difference and I'm not sure where I work that they think this way.

You asked what would be great courses or videos - I'd love to hear more about infrastructure as code, configuration as code and best practices with tools like Terraform, Ansible, Chef/Puppet, Morpheus or even Jenkins/GitLab to run these "playbooks"

This is the best presentation I have seen on the subject: clear, on spot, complete. Thanks!

Whoa!!!! I was just thinking to know more about SRE and this video notification came 🤯🤯

Great video!
As an SRE at a big tech company, we do things a bit different than the well-known SRE concept mentioned in this video. We have dedicated tools teams filled with SWEs working on building the entire CI/CD platform and on-prem resource allocation. We also have dedicated netops, sysops teams working on networks, hosts, file-systems, etc. For SREs, we do the typical work like monitoring, oncall, automate dashboard generation, but the real fun stuffs are building technologies that help make the site more reliable and fast. Some examples are, we built our own monitoring platform, end-device availability observations, ML-powered incident triaging/mitigating, ML-powered service performance tuning, database data integrity detection/restoration, etc. All of the projects mentioned above help make the site more reliable but not necessary focusing on making feature delivery fast.

Moving from Opps to SRE . Great introduction - directly to the point for tech people. Well done.

[eunicenekwa]

Thank you sister. This has made my day. Now I fully understand the differences between SRE and DevOps. God bless ya

[ThaiNguyen-csjy]

One of the best thorough and comprehensive explanations of SRE, or I must say, THE BEST! I love the comparison part between SRE and DevOps so much! Thank you for your work and knowledge, Nana!!

[scubamandan]

Great video. We're currently in the process of budding off from the platform engineering team (I still can't bring myself to say DevOps team) to start a dedicated SRE function. This video illustrates so much the direction I want to take the team, but with some differences as we're currently a very small team servicing a large number of developers. So taking a more horizontal / consultancy type approach. So some challenges there... But I am definitely going to share this video as it really gives a great introduction into much of what we want to achieve. Thank you.

[yawar]

Working as SRE, mostly doing the same stuff, Automation, Monitoring, On support call, etc... Loving it :)

Great videos! Also watched the DevOps one, I especially appreciate how you address the ambiguities. My 2 cents on DevOps and SRE: are they almost the new Dev & Ops, but an upgraded version where both sides now need to have a broader knowledge of the full software life cycle. At the end of the day, each side still have their priorities (speed or reliability) as you can't really ask people to care about everything.

[starwars]

Thank you for your videos! I will be starting my new job as an SRE on monday jumping from it support

[hamza_belmellouki]

Thank you nana!! I was waiting for this specific video!

[sandisosenzo]

I'm a second year computer science student and this is the very first time I've ever heard of such a role named site reliability engineer. I guess there's still a lot to learn. Great video though❤❤

[haimmadmon]

Great description and comparison .Thanks a lot Nana, you are doing a great job
