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**. Greetings from Colombia!

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

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!

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!

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

interesting to see the difference between practical devops and sre. we have a team of devops engineers, but you can see who acts more according to the sre or practical devops roles.

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

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

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.

@@TechWorldwithNana thank you for the video, i learnt quite a lot when embarking on a new role as devops

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.

What a timing Nana, great content as always, thanks for the much helpful info... Thankful for ur service

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!!

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

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

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.

Super informative as always nana. - thank you i take away a few things from this and probably wrong: 1. Job postings i look at, seem to get DevOps and SRE confused or at least blend the two together it would seem...judging by the tool set/overall goals the two disciplines aim for... 2. Wouldn't surprise me if in the future, smaller companies start demanding more and blend both DevOps and SRE discipline together to save money (given that there is some overlap in concepts/goals): DRE (Development Reliability Engineer) or SRO (Site Reliability Operative/tions) :)

I am a SRE for many years , the video is just awesome 👏

Great to hear! Good luck with your new position 😊

Thanks @nana for sharing this video, Great game, as usual :-) I would like to challenge a little bit the sillos we are trying to create between DevOps ( Build ) and SRE ( Run ) . A DevOps Engineer should not focus only on speed, but also on quality , as you mention in your video. SRE is a critical task to ensure we deliver with quality, and is part of the so valuable feedback loop of DevOps. In case the team size grows, once could isolate the roles within a team, but I would rather recommend to keep these people in the same team and exchange the roles in a monthly basis, so they can share the same goal and manage their skills accordingly. Side question: SLA is a key metric to monitor, but I usually found people building their own in house grafana dashboard to observe and alert. Any counter proposal to harmonize this asset?

Fascinating. My take on this is it sounds like a modern, cloud native version of what Sys admins would do back in the day.

Congratulations on one more incredible video. Love your visual content

Which software do you use for designing such an awesome presentation? Thank you Nana for making this video.

This was a really good video. Thanks a ton!

Good explanation however I would like to address your story about SLA & Error budget. SLA is an agreement as you explained, but you mention it's set by the business owner and engineering, typically that won't be the case. After breaching an SLA there is most of the time in the contract a line that would allow the customer some form of reimbursement (money back, opting out of the contract). Most of the story telling is actually about SLO's, which are objectives that are set by the people who own the service (from Product manager, Product Owner and engineering team). This is where the story of Error Budget makes much more sense. You will never go close to your SLA because that would put a high risk of reimbursement. In short and SLO might have the same metrics as an SLA however a SLO should always aim higher then an SLO, because then you are (as you mention) allowed to take risks from your error budget. But also you might have SLO's (let's let latency) that are at the start not an SLA, but after a period you can confidently add that latency as an extra agreement with your customers without making assumptions. This is where the power of history data comes in play. SLO/SLI and Error budgets require it's own video, it's so powerful if you connect the dots, it's for me key metrics that can be understood by everyone in the organisation.

So, to summarize, in the past we had two teams with different objectives: Devs for speed, Ops for reliability. And now we have 2 teams with "different" objectives: SRE for reliability and observability and DevOps for speed in releases and infra provisioning. Nice 🙂👍

@DevOpsLee

2 жыл бұрын

I don't agree with that statement. SRE cares about reliability and observability, they can be either included in teams or act as a consultant to the different teams. They mainly drive improvements forward and will help the teams achieve that next level on topics like reliability/scalability/performance/observability. In regards to your DevOps team, in a "you build it you run it" way, the teams will take the tasks of deployment and infra provisioning on themselves because they have all the know-how of the application. Unfortunately in many bigger/older companies, this is not true and you have siloed teams (dev/infra/qa...). Note: I don't like the term DevOps team, it's a philosophy and not a role.

​@@azzy6543 For me that's indeed a platform team, not SRE. However many teams in the organisation can help and mature reliability within their team without being called SRE. However I would not consider the platform team to be true SRE's as they might have not enough influence on the application code itself.

Hi Nana , could you please tell which software you use for slides presentation? They look really good engaging.

After looking this video (quite nice analysis by the way) it suddenly occurred to me, that SRE relates to DevOps(role) same as QA(role) relates to Developers ;-)

What tools would you say are the most important for SRE? A scripting language, Docker and Kubernetes?

Hey Nana, do you think your DevOps training is suitable for SRE? Or are you planning the release SRE training?

Amazing overview

When you explain SLA you are really talking about SLO. The SLA is an agreement with some kind of consequences, usually financial. SLO is the objective that defines the availability, as an example, and the SLIs are the indicators you measure it with.

amazing content, thank you

your videos are top notch :)
