Thoughts on Unified Observability: One Vendor for Traces, Metrics, and Logs?

Lately been exploring the concept of unified observability, specifically the idea of having all traces, metrics, and logs under one vendor or tool. The promise of centralization sounds amazing—simplified troubleshooting, faster MTTR, data correlation and reduced complexity from managing multiple tools, agents vendor contracts etc.


However, I can’t help but wonder about some of the trade-offs:

Scalability and flexibility: Can a single tool handle the unique needs of different parts of an organization? Ex. Like some solution might be best at some but not others. Is the compromise here for some signals worth it bringing good developer experience since they not have to leave the tool?

Lock in: Though in context of data collection its technologies such as OTEL, Prometheus etc. But I am particularly fan of PromQL since this does not locks in the query language for metrics but with vendor such as Splunk, Dynatrace etc they have different language to query prometheus. Not speaking of logging, tracing here since I am not aware of any standard query language(Though I might be wrong and missing something).

SPOF(Single Point of Failure): If there is an outage with the vendor then your pipeline is halted.

Cost Savings: Big part is advertised as cost savings, does this really save cost?


I’d love to hear your experiences or thoughts.

Which cloud server would you recommend for my app setup?

I am working on a personal project which is a webapp. And I wonder what the best remote server solution is to deploy. My stack is:

* python backend, react frontend. containers are packaged separately and communicate to each other
* use github for code repository
* use github actions/workflows for auto deploy
* use JFrog for docker container registry
* the app uses an sql database to store user data and object storage to store images and videos.
* the app uses ML models
* conventional models such as XGBoost, trained locally
* Small-sized open-sourced LLM models
* atm I don't use kubernetes, but in the future i may use

Here's a link to the system design that I drew: [https://docs.google.com/drawings/d/1iYBULmQBgFhDz8e7JKSV7Kx0u1CBQYnhWG2Vj8OFK1E/edit?usp=sharing](https://docs.google.com/drawings/d/1iYBULmQBgFhDz8e7JKSV7Kx0u1CBQYnhWG2Vj8OFK1E/edit?usp=sharing)

I want the app to be available 24/7. I expect a few hundred requests to backend per day at max. My questions are:

1. any suggestions for my DevOps flow?
2. which cloud service should I use to host this app?
3. what are the recommended registry and host for ML models?

In the past, with the similar setup but without ML models, I have used AWS EC2, S3 and RDS. Back then all I knew was a few Docker commands so packaged an image locally, uploaded to my Docker Hub, and pulled a container to an EC2 and manually run \`docker run\` commands. And I created a PostgreSql on RDS(separated EC2 instance) and opened a communication port to talk to the app. But to be honest, it was complicated because I had to install a lot of stuff(docker, git, etc) on EC2 and the cost was also expensive as a start. Now, I know how to use GitHub actions, I know a bit of Terraform, I also know how to use kubernetes and how to write helm charts. So I'd like to ask an advice on what solutions are available and recommended for me.

My profile is a data scientist and i'm learning CI/CD and DevOps. Thank you :)

Suggestion on complete observability setup for my ORG

Guys, My organisation is an healthcare based and largely relies on Microsoft for everything, I mean everything, they are into Azure Monitor, Log Analytics and etc Microsoft based stack, Now they are building their own monitoring tool to even reduce the security risk of data exposure, I don't feel it is a right thing to build the entire suite on their own, what is the best approach to deal with this? Installing premade open-source stack? Or going for a vendor Splunk, Datadog or Newrelic? Most likely going to another vendor is not smooth a approval in my org unfortunately

Please share your monitoring and observability setup of your's.

Open Source Dev Tool for app delivery, now with a portal

Greetings from the [Kusion\](https://github.com/KusionStack/kusion) maintainers. We are launching Kusion on [Product Hunt\](https://www.producthunt.com/products/kusion) today.

Long story short, it’s an open source dev tool designed to simplify cloud-native app delivery by taking care of the complicated infrastructure stuff so you can focus on building awesome applications. And here's the [slightly longer version\](https://kusion.kusionstack.io).

It used to be a CLI, and we are now adding a dev portal to help visualize everything. (CLI still works if you prefer it)

What are some of the Best DevOps Case Studies to enhance DevOps skills?

I'm looking to further deepen my understanding of DevOps practices and would love to explore some case studies that showcase real-world challenges in areas like CI/CD, cloud automation, especially ***Kubernetes***, or infrastructure as code.

If you've come across any excellent case studies, whitepapers, or detailed write-ups from companies (big or small) that you found particularly insightful, please share them!

A few points I'd love to learn about:

* How teams figured out what was going wrong.
* What tools/approaches do they use to fix it?
* How it all turned out in the end.

If you’ve got any recommendations—blogs, repos, talks, or even your own experience—I’d love to check them out!

Github Actions monitoring a repository not in Github?

Has anyone got any experience using GHA to run pipelines on repositories stored in other Git provides such as Gitlab or Bitbucket?
Is it all done through Webhooks? What is the reliability of this?

Suggestions and recommendations

Hello guys,

I am trying to get a job in DevOps but i dont have experience in that field specifically and everyone expects candidates to do have.

I worked as a network and security engineer first, now i am doing automation with python (3 years experience overall), So i am very confident with those two fields.

I know a little bit of linux, a little bit of ansible and terraform and a little bit of CI/CD.

I have also studied for the AWS solutions architect but i did not take the test yet.

Is there any dummy projects, or follow alongs that i can do to help me gain hands on?

I am also willing to help anyone with their projects if that is possible somehow.

Thanks,

Devops Mentorship

Hello everyone. I am still at early stage of learning devops, And I am looking for mentorship. Someone I can have access to help explain some concepts and strategies and why devops do what they do in various scanarios of real life projects and not just theoretical concepts.

I know there are many resources out there to learn from, but a guided and systematic learning approach can help a lot.

Please you are interested. We can creat a group and begin from there.

Thanks

The Double-Edged Sword of Accountability Groups (and How I’m Tackling It)

I’ve been noticing a theme lately, both in conversations with other engineers and in my own head: that feeling of falling short. In DevOps, where the pace is relentless and there’s always a new tool, a faster deployment, or another certification to chase, it’s easy to feel like you’re not doing enough.

Joining an accountability group made this even clearer for me. At first, I loved the structure, the camaraderie, and seeing everyone’s wins. But then I started feeling this weird pressure, like everyone else was smashing their goals while I was barely keeping up. Accountability groups, I’ve learned, are a double-edged sword. They can motivate and push you forward, but if you’re not careful, they can also make you hyper-aware of how much further you think you need to go.

What’s helped me is reframing the way I see progress. Instead of comparing myself to others in the group, I compare myself to who I was yesterday. I track small wins, celebrate them, and focus on personal goals that matter to me. At the same time, I try to see others’ successes as a chance to learn or be inspired not as a reflection of what I’m lacking.

DevOps (and life) is a marathon, not a sprint. If you’ve ever felt this way, you’re not alone. Have you had a similar experience with accountability groups? How do you make sure they stay helpful instead of stressful? Let’s talk."

Guidance

Hello everyone! Im a full stack developer with around 5 years of experience working with MERN stack, .NET and Flutter, React Native for mobile development. I am pretty content with my work and get paid nicely, but I’ve always felt like learning DevOps and Cloud infrastructure. I’ve looked for resources and guidance and have found plenty of resources but what I actually need help with is the actual roadmap itself as to where to actually start.
I was hoping that anyone with experience would guide me as to where I should start and what “roadmap” I should follow. Any resources, advice would also be appreciated.
TIA!

Recommended books for k8s ecosystem

Hello, so I have just finished KodeKloud CKAD course. I liked it and I feel I have a solid grasp of fundamentals.

Now I am looking for a book (or any recommended resources) on actual ecosystem and approach to managing k8s cluster. Ideally it would be a comprehensive overview with comparison of tools and techniques with clearly stated pros and cons.

Examples:

CI/CD - How do you actually deliver changes (I am sure you are not just running `k apply` manually. What are approaches? Some GH Actions setup with access to the cluster? FluxCD? ArgoCD? I would like to see a good overview of what problems those tools target and what are shortcomings or quirks - when to use each one.
How to structure your codebase \- do you use Helm or Tanka with jsonnet? How much abstraction is recommended? How do you structure your resources and reusable parts?
How do you keep IaC for things that are NOT strictly k8s resources - like plugins and addons you installed, or AWS resources that are not k8s managed (S3 buckets, IAM roles)?
Comparison of Ingress solutions etc.

I hope this gives you and idea what I am looking for. Most things I find on the internet and in books is strictly k8s - so basically what I touched upon in KodeKloud CKAD course. Do you know of any books/resources that actually address what I am looking for?

Thanks in advance 🙇🏻

Advice for this year and future interviews

Hello,

I been learning DevOps for around 9 months, my current job is at Service Desk for 5 years and would like to shift to this new role...

Long story short I been using KodeKloud, Udemy and Youtube for the first 7 months in order to learn and then recently I got into a course in the university about DevOps (6 months long, I do not have a university degree hence I cant apply for a master). My plans for this year is to finish the university which includes Azure and AWS Cloud Practitioner certifications and get certified in CKA/CKS. Apart from that I am working in two projects, one within the university and a second with a mentor.

Recently I was reached out for a Junior DevOps position interview and wanted to experience how an interview looks like. Here is my point, in the technical interview what I have seen so far to succeed, you need to basically remember everything, every technology command and its flags, every syntax for a pipeline, script, IaC... and you aren't able to get into the documentation even to check some syntax. I do know the concepts and how the technology works but most of the time I need to check my notes for syntax or commands since I'm not writing Dockerfiles or deployments in K8s or making bash/python scripts for 8h a day.

How should I go about this right now in order to improve for interviews for the future? I am planning to look for real interviews in 6-9 months
