Great video Nana ... What tools do you use for your presentation? Where do you get the artworks?
0:15 years
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!
I am seeing pattern of SDE moving into an SRE role more and more nowadays, can you explain your reasonings behind it? Thanks!

I am an SRE and my pain portrayed as a poem in this video. #respect
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!
thanks! it helps me understand both sides of coin 🤝
So are you saying DevOps roles are more enjoyable than SRE in general? Why?
Do anyone know what the is the team name that SREs are under?
@@dirtydan8044 I think that's subjective
@@pramilaaranvoyalrajan3361 Mainly PSS team or Prod support team
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!
hii Gregg, could you please help me learn DevOps, any resources, any roadmap, please help me. thank you
Wow, that's amazing! Happy my videos could help you in your transition to DevOps :) Thanks for sharing!
Whoa!!!! I was just thinking to know more about SRE and this video notification came 🤯🤯
Cool :D
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.
This is the best presentation I have seen on the subject: clear, on spot, complete. Thanks!
Thank you nana!! I was waiting for this specific video!
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"
Moving from Opps to SRE . Great introduction - directly to the point for tech people. Well done.
Great description and comparison .Thanks a lot Nana, you are doing a great job
Thank you sister. This has made my day. Now I fully understand the differences between SRE and DevOps. God bless ya
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.
I was just in a similar situation as well. Have you been able to achieve your ideal operational efficiency?
Another good job Nana! Thank you!
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!!
Amazing videos ! I like so much your channel. Congrats nana and thank you !
What a timing Nana, great content as always, thanks for the much helpful info... Thankful for ur service
Great video Nana! As an SRE, this is one of the best explanations I've seen!
Thank you so much, great to hear that from an SRE practitioner! :)
@@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.
Working as SRE, mostly doing the same stuff, Automation, Monitoring, On support call, etc... Loving it :)
I am a SRE for many years , the video is just awesome
👏
Awesomeness and Information Overloaded! Thanks!
I’ve been waiting patiently for this 🤩
Congratulations on one more incredible video. Love your visual content
Just AMAZING , Keep it Up Nana 👏👏
I love your teaching Nana. Even a kid will understand your calm voice ❤
The presentation and content are very nice, greatly describing things by animation.
Thank you so much.. I do all these stuff everyday but this video helped me to explain to someone what I do everyday..
I was looking for this video to explain on SRE. Thanks a lot to hear us and making this.
My pleasure! I'm really glad that the video is helpful for you guys!
Thank you Nana, always giving us amazing content
Fascinating. My take on this is it sounds like a modern, cloud native version of what Sys admins would do back in the day.
Awesome! That clarified a lot! :D Well explained! :)
Very keenly explained, am an SRE we do all the things she mentioned.. good video!
Thank you. Great video.
This was a really good video. Thanks a ton!
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) :)
Very well defined. Thanks.
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.
Thank you for your videos! I will be starting my new job as an SRE on monday jumping from it support
Right in time! Just spending my first week as a junior SRE (but experienced sysadmin). 😃
Great to hear! Good luck with your new position 😊
Very nice explanation Nana.. I clearly understood SRE and how it really works.. Thanks for the clear explanation video.
i think something missing here is the concept of "reducing toil." SRE have a lot of manual tasks. The team should look towards automation through both tooling and creating new applications that can do activities for SRE team.
Amazing video, Thank you 😊
Nana your content is so good and relevant. Thank you!
Thank you Erik! 💙
First time as an SRE thank you for sharing this video it helps me well :)
Great Content!
My favourite Tech instructor
Thank you Nana..helping me now..great 👍
I would appreciate your effort nana 👍
amazing content, thank you
Thank You Nana, Awesome explanation !!
Happy to hear! 🤗
Great video as always .!
Very insightful thank you! Now I know the difference :)
As an SRE I like building and setting up the tools. For example writing scripts that detect changes and alert based on those incidents. But actually handling those incident is a pain in the ass because it involves a lot of communication with other people, emails etc
Great..explanation , keep doing the great content.
Nana u are just awesome... this video helped a lot
Good video. I think what you explained as SLA is actually SLO. SLA is more of a commercial agreement that specifies kind of fine when you fail to meet SLO. You also missed one very important topic which is SLI.
Thank you for the great content! Looking forward to subscribe and learn further with your channel 😊
Thanku for amazing content
About SRE, this is best video to explain.
Awesome explanation. Now I have better clarity regarding SRE and DevOps.
Thanks Sujeet, happy I could clear your doubts about it :)
좋은 영상 감사합니다!
Thank you, great explanation :)
Great content! Thank you! :-)
as usual, another masterpiece from NANA!
Great video!! :) I was wondering what the difference is between the two. My question now is what tools and skills should SREs focus on or have? :)
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?
Thank you so much as always amazing video
Nana...you are the best...!!!!
Nana rocks!
Hey NANA Loved the video as always. Just one suggestion, whenever your add started please add promotion alert or their logo in your video, it will help to differentiate the add and your content. In current loft promotion, after 10sec it feels it has ended but still it was going on.
bhaiji aapke jaise logon ki vajah se hi hum indians ki beijatti hoti hai. Har sponser chaahta hai k uske ad ko viewer neglect na ker paaye and that is what she is trying to do or aap us per lecture de rahe ho.
your videos are top notch :)
Thanks Nana. Really very well explained! If possible can you please try to add more videos SRE. May be some scenarios that you have seen in SRE
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.
Hey Lee, thanks for sharing with great details! I agree that this topic requires its own video, I didn't want to explain all the details in this SRE overview video
@@TechWorldwithNana I believe you touched on the important items and made it clear what the differences were so kudos for again explaining to a broader audience.
Also agree with your point, SRE can go pretty broad in topics.
I am btw (because you asked in your video) a SRE Lead/Manager.
Thanks Lee for your feedback and for sharing your valuable knowledge as an SRE lead here in the comments with others as well. There is definitely a need for more information on these topics in the community.
Hello Nana! Great Video as always. I owe my entire DevOps Journey to you. From becoming a complete Noob to now Working Full Time as a DevOps Engineer, You are my saviour. I'm now trying to transition to SRE. Can you help me understand what Tools should I learn for this? Also a Zero to Hero on SRE would be absolutely wonderful ! Anyways Thanks for Everything !!!
Amazing overview
Thanks for the awesome video.Love the visualization and presentation❤️
I too do love them... I don't know how she does them and where to get the templates...
Thanks Jayanth, happy you like the visuals :D
What app do you use to make them? And where do you get the templates?
Which software do you use for designing such an awesome presentation? Thank you Nana for making this video.
Awesome presentation Nana!! What tool did you use for it? Greetings from Asunción - Paraguay
You are my favorite teacher 👩🏼🏫, I’m Chinese, I like your voice,😀
i learn a lot with your videos!! cheers from argentina!!
Great to hear Marcos!
excellent video
Thanks 💙💜
Hi Nana , could you please tell which software you use for slides presentation? They look really good engaging.
Thank You mam....Please make a series of videos on SRE
As a SRE we are setting, 1. we will collect metrics of different servers and displaying on Grafana dashboard ,2. operational alerts to respective teams. 3. ONCALL on P1/P2 incidents. 4. Submitting the RCA to clients 5. working on the Incident action items with the developement teams.
is SRE Production Support?

Nana I love you. The best teacher in town
@Nana: Thank you for the information in this video. Have you created any video about Pulumi?
As usual very clear with Realtime tools whiteboarding
Excellent content
thanks for video
Thanks Nana.
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 🙂👍
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.
To add to what @Lee Van Steerthem said SRE's usually also provision infrastructure. In my org I am an SRE but our team is called AWS platform team.
@@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.
Thanks Nana🙏
thanks Nana
Ma'am, please make a video on what is the role of a Developer Advocate and What is Chaos Engineering ??
You are great Inspiration
Thank you Amit 💙
Thank you very much for this Video. I am looking for a serious game introducing SRE. Do you have any ideas, tips, examples or links ? Thank you in advance
