Bootstrap your DevOps, Cloud Architect, Data Engineer career

This post comes from the struggle I see in the community, especially with young people not knowing how to start their career in those fields.

I am a DevOps and all of those titles since 10 years now and own my small company with few clients. Being interested in education I have decided to start offering support and guidance for growing careers.

I would love to offer a free program in which I want to develop some interesting projects that can be of good use for my company while offering my time in exchange and experience to grow and work in real job scenario.

1. What do I offer?

Free support on guiding you on resources to study and fill the gap of knowledge you have. Teach you and make you use a real world methodology of work, tracking activities, code reviews. Support is best effort since I am actively working on projects, but I am serious of being able to find the right amount of time to dedicate.

2) What I want in exchange?

Serious people and motivated. You can work with your pace, no obligations on time, you dedicate the time you wish, but you need to be serious about that (no 30 minutes per day, I doubt this could be useful for anyone)

Let's now talk about projects I want to implement:

1. Data Streaming pipeline (Kafka, Airflow, Spark) for a Market Data application. There is an interesting article on Medium made with docker compose, let's bring this to production!
2. LLMops: I am building some models that I want to automate the deployments in production environments with proper pipelines.
3. Microsoft Azure Terraform modules: create modules to provision resources on Azure, an opportunity to go in depth with those technologies.

Not being able to scale with this methodology I am only find a small number of people, unfortunately I am not able to follow tens of people, but rather more 2 or 3.

Also if I need to follow you, it would be better you are not that far from CEST TZ, as otherwise the collaboration could be compromised.

Unexpected cloudflare when accessing my aws website

I was having trouble accessing an aws linux machine that I have been running for a couple of years on AWS. It was very slow. Then I got a message that claimed to be from Cloudflare saying there was some kind of weird traffic coming from my IP. This seems crazy. I've never signed up for Cloudflare. I use Route 53 DNS. The message asked me to copy a weird looking command into a terminal. I noticed that it was piping a weird string into base64 decoder and then into bash. Then it a window popped up asking me to put in my password to install a helper. No thank you. I had to reboot my mac to get rid of the popup.

I rebooted the linux machine and all seems ok now. Does anyone know what was going on?

Looking to move away from Github

I don't want our code to get merged into some black box AI so we're going to look at our options to leave Github. We want our repos to be private and hosted in the cloud without too much work on our side. Has anyone else had much experience with these and is there anyone I'm leaving out?

Gitlab
Bitbucket
Assembla
Beanstalk

Find the exact version of libcrypto3

Let's pull a nginx image and run it in a container.

When I look for the libcrypto3 lib using: find / -type f -name libcrypto

I get /usr/lib/aarch64-linux-gnu/libcrypto.so.3

Now I would like to find out, which is the exact major.minor.patch of this lib.

We cannot install any image-scanner or additional packages.

Devops Projects

Hello All,

I am passionate about learning Devops from scratch, i did few projects for practice and learning but I am still short in experience. Requesting the experts help on sample projects which I can do in my own which are similar to industry standard application as doing projects helps me learn faster than.

Appreciate the help!!!

RailFlow, a rails-first routine for AI-assisted delivery. CI gates, contracts, and a status ledger. DevOps folks, what would you change

I wanted a simple way to keep quality as policy, not opinion. RailFlow lays a few rails first: tests in watch mode, a TDD playbook, contracts at boundaries, and CI gates for coverage, a11y and performance, security, and contracts. A status report lives in the repo so automation knows where to resume.

TL;DR: five Markdown files under docs/guide/. 01 is the method playbook. 05 is a status ledger for handoff. 02 03 04 are the dev artifacts that ChatGPT can draft. Merge is blocked when gates fail.

I would really value your take on the gate set, artifacts as policy, and any pipeline pitfalls I should document better.

Why is managing cloud server schedules such a nightmare no one warned me about?

I thought setting up start/stop schedules for my cloud servers would be easy. Just set the times, hit save, done. Nope. They keep running outside the schedule, and now the bills are making me regret everything.

I’ve checked permissions, roles, triggers, all of it, and it still feels like there’s some hidden setting messing it up. Anyone else run into this? What weird gotchas have you hit when trying to automate cloud server stuff?

Also, if you know a way to check the schedules without digging through a mountain of logs or alerts, that would save me a lot of pain.

Questions about versioning my infra and adding a new environment

Where I work, we’re in the middle of developing an integration with Amazon. However, after doing a bit of convincing with management, I was allowed to create a new environment (homolog) for QA and the client to test new features that haven’t yet been reviewed appropriately to be deployed to the staging environment (it's our pre-production env). Before, this was done in develop, but we constantly merge feature branches into develop, breaking some flows there (we’ve broken a few flows during some important meetings with the client).

That said, I became responsible for creating the new environment, and in the meantime, the integration is on hold. Currently, the infrastructure is a rather messy mix between Google Cloud (Run, Functions, Vision, Storage, and databases) and Cloudflare (Workers, R2, D1, Workflows, and Queues). Altogether, we have more than 20 services, and it’s safe to assume that any service on GCP or CF will use tools from the other, so manually porting the infrastructure would take a long time, and I’d probably get lost quickly.

I was thinking about creating a repo to version all GCP infrastructure using Terraform, but I’m still not sure how I’d do it with CF, since it has its own configuration declaration file, wrangler.jsonc, for each worker.

Does anyone have an idea of the best way to handle this? Should I do everything manually, version only the GCP and keep the CF configuration within the workers, or version everything using Terraform or some other idea?

Either way, one problem I’d face if I went with Terraform only for GCP or for both would be migrating the current infrastructure to code. Is there any tool to automate this?

Skill assessment exam. Yay/Nay?

Hi guys,

Just passed an online tech interview with a company and they would like to proceed further to an on-prem, 2h skill assessment exam on a coding platform, where the coding challenge would include multiple questions and coding challenges from multiple areas.

I was told to expect cloud related scenarios, docker & docker compose challenges, solutions to helm and k8 tasks (writing from scratch a k8 deployment), TF and maybe CF / CDK topics, pipeline assignments, all this WITHOUT any documentation or any tool allowed.

This means: no google searches, no official documentation allowed for any service, no gpt, nothing.

All should come from the top of one`s own head.

LE: How are you guys feeling about such a challenge and would you accept it?

I'm having mixed feelings...

LE2: The platform does not allow for - - help commands (eg: tar - - help / k describe resource) since the platform offers only a coding window, a run/test button and a submit code button.
No actual CLI, from what I can see.

DevOps Engineer from tech sales?

Hi, if somebody could provide some career advice it would be greatly appreciated. So I graduated this May with a CS degree and I’m having trouble finding a full-time position. I have internship experience in automation/analysis and Python scripting. In any case, I have a possible offer in a BDR position though I am not very excited about cold-calling, but I am also unemployed right now and beggars can’t be choosers. Would it be possible to switch careers later on (after 6 months or so) from BDR to any relevant roles that would potentially give me DevOps experience? I worked in the transportation sector and I really liked helping out a good cause, indirectly building the infrastructure of a city through my intern code. Does anybody have any advice?

Our auth service has been making 50k unnecessary calls to user DB every hour for who knows how long

Was looking into why our DB costs spiked last month and found our auth microservice hitting the user table way more than it should. Turns out it's fetching full user profiles on every token validation instead of just checking the token cache.
Someone "optimized" the auth flow six months ago but forgot to actually use the cache they built. So we're doing full DB lookups for data we already have in Redis.
Not a security disaster but definitely not great that a service can just hammer our DB without anyone noticing. Our monitoring flagged high DB usage but nobody connected it to unnecessary auth calls.
Makes me wonder what other services are doing dumb stuff that looks normal from the outside. Like our security tools see "auth service talking to user DB" and think that's fine, but they can't tell that it's doing it 50x more than it needs to.
Kind of annoying that we have all this fancy cloud security stuff but it can't tell me "hey this service is being weird compared to how it normally behaves."

We rewrote our ingest pipeline from Python to Go — here’s what we learned

We built Telemetry Harbor, a time-series data platform, starting with Python FastAPI for speed of prototyping. It worked well for validation… until performance became the bottleneck.

We were hitting 800% CPU spikes, crashes, and unpredictable behavior under load. After evaluating Rust vs Go, we chose Go for its balance of performance and development speed.

The results:
• 10x efficiency improvement
• Stable CPU under heavy load (~60% vs Python’s 800% spikes)
• No more cascading failures
• Strict type safety catching data issues Python let through

Key lessons:
1. Prototype fast, but know when to rewrite.
2. Predictable performance matters as much as raw speed.
3. Strict typing prevents subtle data corruption.
4. Sometimes rejecting bad data is better than silently fixing it.

Naming cloud resources doesn't have to be hard

People say there are 2 hard problems in computer science: "cache invalidation, naming things, and off-by-1 errors". For cloud resources, I would say the naming side is way more complicated than the usual.

When coding, renaming things later is easy due to refactoring tools or AI, but cloud resources are usually impossible to change. I wrote a blog post covering how to avoid major complications by simply re-thinking how you name cloud resources and (hopefully) avoid renames.

Happy to hear thoughts about it and/or alternatives.

Need advice on http3 reverse proxy

I'm developing a real time chat system using http3 for the communication between client and server. Right now it works fine locally by connecting directly to the server with a long-lived connection. I was thinking of setting up a reverse proxy to add some security measures. Now, i know that nginx has support for http3, but as far as i understand it, it just enables http3 for the client and then redirects the request to the actual server via http2 or 1.1. That won't work for me since the service itself is http3. Could anyone correct/guide me on this? What options do i have?

Also sorry if this is not the most correct sub to ask this in. Any help is appreciated

New in DevOps & loving it — but concerned about long-term career prospects. Need advice.

Hey folks,

I recently transitioned into a DevOps role at a service-based company and I’m really enjoying it. I’ve been learning a lot — Kubernetes, GCP, Docker, Jenkins, and more.

However, I’ve noticed quite a few posts here where people with 3–4 years of DevOps/SRE experience are struggling to find jobs. That got me thinking…

My questions:
1. What’s going on with the current tech job market?
2. For someone early in their DevOps career, what should I focus on to stay relevant long-term?
3. I’m considering learning MLOps since AI is booming — would that complement DevOps skills?

My goal: Keep growing, eventually specialize in a niche that will stay in demand, and future-proof my career.

I’d love to hear from experienced folks — what skills, tools, or career moves helped you stay ahead?

Thanks in advance! 🚀
