Kubernetes Requests and Limits: A Practical Guide
Most cluster instability comes from resource settings nobody revisited. Here is how requests and limits actually work, and sensible defaults to start with.
Read articleWe build and teach Kubernetes, OpenShift, DevSecOps, Linux servers, CI/CD pipelines, cloud platforms and AI infrastructure.
Infrastructure projects for companies and hands-on training for their engineers. One team, from Linux servers and Kubernetes to DevSecOps, cloud and AI platforms.

What we do
Everything we teach, we have run in production
Pick the side you need. Same engineers, same playbooks.
+4Kubernetes & OpenShift Platforms
Clusters your teams can trust, upgrade and scale without fear.
Fixes: Nobody wants to upgrade the cluster

How we work
From first call to a team that owns it
Every engagement ends with enablement, so nothing depends on us forever.
- 1
Discovery call
A 30-minute conversation about your problem, stack and constraints.
- 2
Assessment & plan
You get findings, a proposed approach and an estimate before any commitment.
- 3
Delivery
Weekly demos, everything as code, and full access to our work.
- 4
Enablement
Our Academy trains your team to run what we built.
Why FlickOps
Engineering and teaching make each other better
Clients get engineers who can explain their work. Learners get trainers who do the work.
Practitioners, not presenters
The engineers who teach our courses work on production systems. What they teach is what works.
Real incidents become labs
Failures we fix for clients become troubleshooting scenarios, so learners practice what actually breaks.
Everything as code
Infrastructure, pipelines and documentation are versioned and handed over. No black boxes, no lock-in.
