I donāt normally enjoy much of the content that comes out of the CNCF but in this particular case this guest blog post on how DevOps is āmisunderstoodā is actually a great read. I empathize with a lot of the points made here and agree. š It also makes me want to write a follow-up blog post in response to this, because thereās another aspect of āmisunderstandingā when it comes to the āPlatform Operatorsā as the author puts it here that Iād like to discuss š #DevOps #SRE
DevOps is not a role
Please stop hiring for āDevOpsā X.
There is no such thing as a āDevOpsā X.
DevOps is a cultural practise.
Read about it here: https://en.wikipedia.org/wiki/DevOps
Soā¦ The last couple of days for me at my day job has been figuring out how to tier our various environments and setup some kind of tiered Prometheus.
Federation was never going to work out so well for me because you canāt scrape 10-20k time-series of another Prometheus server, the scraping loop will just timeout consume that amount of data.
Turns out there is a new feature in Prometheus v2.34.0 called āAgent modeā that allows one to run a Prometheus server in such a way that it does two very important things:
- Sends/writes all time-series it locally scrapes via Remote Write to another Prometheus server
- Keeps a WAL (write-ahead-log) to ensure no metric is ever lost and,
- only deletes the WAL entries on a successful write to the remote Prometheus.
This setup allows (along with appropriate External Labels) to have a very nice tiered Prometheus setup where you effectively have a central Prometheus server (with no scraping configuration, except for Prometheus itself) that acts as the Remote receiver for Prometheus agents.

Bahahaha just accidently came across this article and thought Iād share it with yāall.
DevOps is not a programming language, itās not a tool, itās not a technologyā¦ā¦.then what DevOps is?
It is a combination of Development and Operations or Itās a collective responsibility of the developers and operators.
Every time I get called up by a recruiter, or try to hire myself into my team (Iām a Lead SRE) I keep telling them:
DevOps is not a āthingā, it is not a role. There is no such thing as a DevOps Engineer.
Iām glad some folks out there actually know what da fuq theyāre talking about š #devops
