I am a MERN developer and recently I read about DevOps. Can anyone tell me how can I learn DevOps in easy and best way?

(Any kind of help is welcome - playlists, courses etc.)

Need ideas: 15-min interactive DevOps session for our CFO (non-technical)

Hey folks, I need some help.

I’m a Cloud Architect on our company’s DevOps & Platform team. Next week, our CFO is visiting our Digital Technology division, and my manager has asked me to run a short (max 15 min) interactive presentation or mini workshop to introduce DevOps and Platform Engineering to him.

Here’s the catch: the CFO isn’t technical at all. He’s a finance guy through and through.

Any creative ideas on how to make this engaging and simple enough for a non-technical audience? Maybe a hands-on analogy, small task, or demo that shows how DevOps supports software development and operations?

Would really appreciate any thoughts or examples! 🙏

Server automations like deployments without SSH

Is it worth it in a security sense to not use SSH-based automations with your servers? My boss has been quite direct in his message that in our company we won't use SSH-based automations such as letting GitLab CI do deployment tasks by providing SSH keys to the CI (i.e. from CI variables).

But when I look around and read stuff from the internet, SSH-based automations are really common so I'm not sure what kind of a stand I should take on this matter.

Of course, like always with security, threat modeling is important here but I just want to know opinions about this from a wide-range of people.

Conferences for devops


Hi,
Because of my good performance, I have a €1,000 bonus to spend on conferences, workshops, certifications, and anything else related to DevOps, cloud technology, software, AI, and soft skills UNTIL DECEMBER.

I'm bored with those events, and I have a lot of certificates, so I just want to spend the money on a trip to Europe with my girlfriend.

I am looking for a conference that lasts 2-3 days and is not too expensive, as I want to spend the money on relaxing, food, and travel.
I will need to provide receipts to get this bonus.

All ideas are welcome!

DevOps Contingent Labor

Are any of you using MSPs, partners, consulting agencies, etc. to scale your DevOps practice? If so, who are they, and are you happy with them? Do you see high turnover? What's the average lead time to on-board someone new?

Debug & Chill 4 - RDS Proxy, EKS, and IPv6—How?

🚀 New episode of Debug & Chill is live!

This time I ran into a strange issue: connecting to an RDS Proxy from EKS (dual-stack) would just... hang. No logs. No clues. Just sad pods. 🥲

Turns out, RDS Proxy doesn’t support IPv6—even though RDS itself does.

The fix? A bit of DNS magic with CoreDNS, some network sleuthing, and a weird-but-valid “Option 2.5” involving manual DNS overrides. 😅

If you're running IPv6 in Kubernetes, you’ll want to read this one: https://royreznik.substack.com/p/rds-proxy-eks-and-ipv6how

DoIt DevOps Support is Trash Now - What Alternatives Are There?

One of my companies has used DoIt for several years to provide DevOps support to our application.

It was pretty nice because they offered free support from a senior DevOps engineer if you moved your AWS account under their umbrella. You could get support whenever you needed, 24/7, all completely free. It wasn't the best support as it was fairly high level, not in the weeds actually configuring and coding, but it was beneficial to us as expert directional support, and again it was free. They made something like 25% from your AWS spend as they received better rates from Amazon, so it was a win/win.

However they recently changed their model to charge $750 to escalate tickets to support. Like many companies, they try to route you through AI bots instead. We tested asking queries to AI engines (ChatGPT/Grok) and comparing to DoIt's AI bot, and predictably the responses are almost identical, meaning their chat bot offers no extra value. They are trying to earn their 25% for doing nothing. And $750 for a call is typically too much to pay for the type of support they offer as it's pretty bare-bones.

Sigh... that's capitalism I guess.

Now that DoIt is trash, are there any good alternatives to them that still offer free senior devops support in exchange for moving your AWS servers to their portfolio?

Need some advice on working in devops

Hey guys,
would appreciate any advice, kind of have a weird background.
I got my first job as a graduate cloud engineer 4 years ago, worked for 3 years and was unfortunately made redundant almost a year ago, all of this was in the UK.

idk if what I did in the mean time matters but I can elaborate if needed, mostly spent the time travelling, volunteering and attending a language school.

I'm a US citizen and have a place to stay with family in the US. Didn't really want to move to the US since I didn't grow up there and find it kind of intimidating due to the news. But I realised the visa sponsorship requirements were holding me back in the UK.

My experience I think maybe aligns better with what could be considered as DevOps, I worked with CI/CD platforms such as Jenkins, AzureDevOps, I used a lot of terraform, have some experience with K8s (using googles GKE). I mostly have experience working on GCP, but I have some exposure to AWS and Azure.
My roles at work usually were around monitoring k8s resources and and making sure our product was stable.
But to be honest I wasn't really happy with my work experience, I work for a consultancy and they had me placed with a large organisation for a year and half, but during that time except for helping set up initial product they didn't really have any work for me. After that I probably spent about a year and half on the bench developing internal tools for the consultancy (mostly using azure devops, python and terraform)

I'm sorry if there are any superfluous details, but I want advice on what my approach should be when applying to jobs in the US?
I feel like my skills are really lacking when compared to the amount of time I have worked, what courses/ projects should I undertake to make sure my skills are up to date.
How do companies usually assess somebodies abilities?
Is this the right place to post this?
What platform is a good place to search for jobs and what job title should I use when searching for jobs?

Thanks.

Junior DevOps interview

Hey everyone, I'm a fresh graduate with some cloud certs but no professional experience. I have a technical interview where I'll get an infrastructure/architectural case study to solve over one day , then discuss my approach.

The company said it's about "analyzing, designing, and proposing solutions" to understand my thought process and problem-solving approach. It's for a junior cloud/DevOps role.

I'm honestly nervous , are there any ressources that might help with that just to practice little bit or help me during that day please !

Default SSH config on AWS Lightsail

Hi everyone,

I'm new to this stuff and just fired up my new AWS Lightsail and ran these two commands:

sudo apt update -y
sudo apt upgrade -y

Mid-way I got a prompt saying that a new version of the config file was available but the version installed currently has been locally modified. Should I install the maintainer's version or keep the local version currently installed?

When should I go for what, and what are the trade-offs? Thanks in advance!

Looking for feedback on cloud engagement strategy for mid-size IoT company (AMPECO use case)

Hey folks,

I'm preparing for a business role interview at a cloud services provider (Europe Cloud – GCP & AWS partner), and part of the task is to pitch a go-to-market strategy for a real client.

I chose AMPECO, a Bulgaria-based EV charging platform with 100K+ charging points across 60 countries. They run on AWS (ECS, RDS, CloudWatch, Terraform, etc.), and their challenges revolve around:

Elastic scalability (high concurrent usage)
Long-term data archiving (massive telemetry + session logs)
FinOps issues (cloud cost visibility per tenant/client)

I’ve proposed:

Infra audit + potential GKE migration or ECS tuning
BigQuery + Coldline for multi-tiered storage/analytics
FinOps PoC via Datadog, GCP calculator, or AWS CE tools

Would love your feedback on:

1. The realism of the pain points and cloud proposals
2. Gaps I may have overlooked (especially on the data/FinOps side)
3. Whether you've seen similar companies approach scaling differently

Happy to hear any thoughts.

Is the Scaler DevOps course worth it? and does the certification get recogonized in the industry?

I am a fresher working as a data analyst. But I have contributed to real world projects through my internships and college club, and have explored DevOps. I want to get a job in DevOps/SRE, but I am not able to get shortlisted to any interviews. Should i do the scaler devops course, so that i also streamline my skills and also get the placement guidance. Is there anyone who has already done the course?

🎮 Docker Is Like a Game Cartridge System

Do you remember that click when you put game cartridge inside console?
No install, no setup, just press and play. Very simple.

This is what Docker feels like.

Your computer is the console.
Old apps? Like games in 90s on PC — insert CD, install drivers, change settings… and maybe it crashes with some weird error.

But Docker is different. Each container is like a game cartridge.
It already includes:

The app (like the game)
The tools it needs (dependencies)
Settings (configurations)
Even small OS inside (game engine)

And the best part: you can run it anywhere.
Laptop, office computer, cloud server — all same result if it has Docker.

You want to run many apps? No problem.
Insert many cartridges. Like WordPress, Node.js, MongoDB — they all run at same time, without fighting each other.

Want to stop one? Just remove it. Others keep working.
Want to share it with friend? Send the cartridge (the container) — they get same thing exactly.

Long Running Celery Tasks With Zero Downtime updates

I developed an app that lets users submit "validation tasks."

On the backend, I'm handling these with Celery + Redis + MySQL to track task states. Each job can take up to 1 hour to complete.

Right now, Celery is running inside a Docker container, hosted via Coolify.

I'm trying to figure out a clean way to upgrade or redeploy without any downtime — and more importantly, without affecting any running jobs.

Coolify has built-in environments, so I can technically do blue-green deployments and switch between them. But my main concern is really about the running tasks — I don’t want to interrupt or lose any of them during a switch.

I have some ideas in mind, but I’d love to hear your thoughts, especially if anyone has gone through a similar setup or solved this in a clean way.

Cert expired (again). Built a tool to stop the madness, Curious what DevOps folks think

You know that moment when everything breaks on a Sunday morning because someone forgot to renew a TLS cert?

Yeah. Me too. Too many times.

So I built **a tool, (I don't want to post the link here, because I don't want to spam, I'm looking for feedback)** a certificate monitoring and management tool built for *real-world* DevOps setups.

It handles:

* Public domains, keystores, cert folders
* Internal mTLS certs, air-gapped systems, embedded devices
* Azure Key Vault, HashiCorp Vault, and more coming soon
* Offline-friendly agent (keymon — [npm link](https://www.npmjs.com/package/keymon))
* Expiry alerts, tagging, environment grouping, ownership context

Basically: stop the tribal knowledge, spreadsheets, and “who owns this cert?” fire drills.

Curious how the DevOps crowd is managing internal certs these days, scripts? Prometheus exporters? Or just hoping Let’s Encrypt doesn’t let you down?

Would love feedback if you want to give it a spin, let me know and we can chat "offline", or just roast it if you hate certs as much as I do 😂

Why Observability Isn’t Just for SREs (and How Devs Can Get Started)

Almost every other day, when I scroll past r/devops or r/sre, I see a post like this asking how a dev can get started with devops, observability, etc.

I've made a blog as an attempt for anyone lost to find their way into observability and a wake-up call for devs to they should think about observability more actively today than ever before!

Best path to learn DevOps fast with structure

Hi everyone 👋

I am working a full time 9 to 5 and I want to become a DevOps specialist as fast as possible. My goal is to build strong foundations quickly and then start working on my own projects, finding a DevOps job or starting taking small freelancing/consulting DevOps gigs.

I am trying to choose between three options:

1. TechWorld with Nana bootcamp: very visual and structured but a bit expensive and not always in depth according to feedback?
2. Cloud Engineer Academy with Suleymane: focused and looks serious but I do not know much about the results?
3. KodeKloud: very hands on but harder to stay focused or follow a single clear path as its a pick and choose and no real build up link between each section?

I personally feel that when you are busy with a full-time job, it is better to follow one structured course instead of jumping between free resources or YouTube. Otherwise it gets too messy and I lose time or motivation.

What would you recommend if you were in my shoes?
Ideally I want to build real world DevOps skills and be able to work as a consultant or freelancer in 8 months (if that even possible :D)

If you have experience with any of these or took a different fast track that worked, I would love to hear about it. Thanks a lot!
