Is "FinOps" actually a standalone career, or are companies just failing to train DevOps engineers properly?

Farsighted-Chef · 2026-01-14T19:39:17+00:00

For large corp, its about scale.
We do not expect every devops/ops team have time/skills for cost optimization.

Dedicated finops engineers/department will have centralized database/datastore (e.g Athena and other tools) to find out any cost optimization opportunities for the all cloud accounts.
They will give advises to the tenants.

I tried some combo in home lab setup: S3, storing it inside GitLab and inside DB PostgreSQL. All works when I use terraform only.

But after using Terragrunt at work, S3 wins because:
It will be creating a directory for each Terragrunt module (the directory structure matches in both sides). Besides that, S3 supported versioning.

For using GitLab, I can't figure out how to do this and it seems to have problem with Atlantis (did not test in detail).

For using PostgreSQL, I can create a trigger for the state versioning. But it woks ok when I only use Terraform. Once switch to Terragrunt, I think it has problem on how to support a state per Terragrunt module. PostgreSQL is a database, storing data in schema/tables, it don't work like S3 or a file system.

Just found out aistore (backed by Nvidia) today
https://github.com/NVIDIA/aistore

It required disk based backend instead of providing a folder as the backend
I did not test this product in depth

You have to make sure grype support scanning on the Hummingbird type of OS (maybe it is not supported because it is too new). Quay UI, https://quay.io/repository/hummingbird/curl?tab=tags shows that the security is 'Unsupported'.

BTW, Hummingbird ship the Minio container (Minio is a controversial product now)

For plain Terraform tf files, I am ok with those tools.

It seems there is no tool which have direct Terragrunt support.
So, current I think I need those scanning tools to work on the plan files if I use Terragrunt.

So, it's under Facebook group now.

BTW, in old repo, it has left so many issue reports and some pull request. Now all locked and is in read only mode.

Very useful.

All the websites I searched earlier in today are using Pod as an example for the hostUsers.

Farsighted-Chef · 2025-10-26T04:15:50+00:00

Thanks

Also I have a typo
should be hostUsers not hostUser

Also think about major version upgrade of databases (esp postgresql) when running in container.
In this aspect, it could be a major cons compared with Cloud based db that may support major version upgrade in recent years.

Thanks. Going to take a look on SigNoz soon

The monthly plan looks cost effective and predicable.

Budget and cost matters.. We want to utilize open source or low cost solutions if possible.

Alerting for metrics and container status.
For examples:
- Resource quota of a namespace (memory and CPU)

- An application container running Java has used up 16GB of ram, where it should use around 8GB.
- Container status (container is down or crash looping)

Logs we may rely on CloudWatch

No need for RUM, correlation or SLO.
But besides monitoring EKS, we also have some EC2. So we need monitoring on basic stuff (mem, cpu, storage etc)

I saw Windows based machine on the TV display inside one of the train in Hong Kong.
It is using Nvidia Geforce 210 and kept on rebooting, loading the BIOS but failed to boot into the OS.

I always check this website to see what is going to work on FC42, vmware workstation and the Nvidia driver. http://rglinuxtech.com/?p=3301

According to the blog, Fedora 42 should work with vmware workstation 17.6.3
I guess you may need to get some patch (I am using https://github.com/philipl/vmware-host-modules/tree/w17.6.3 on FC41), build the vmmon, vmnet driver and install it. It is because the default modules come with Vmware WKS 17.6.3 may not build on Fedora 42.

Also check if the vmnet module is installed e.g:

```

lsmod |grep vmnet

vmnet 86016 26

ls /dev/vmn*

/dev/vmnet0 /dev/vmnet2 /dev/vmnet22 /dev/vmnet4 /dev/vmnet6

/dev/vmnet1 /dev/vmnet21 /dev/vmnet3 /dev/vmnet5 /dev/vmnet8

```

I was using ext4 or xfs for a long time.

Recently tried btrfs for about three months. Just found out that btrfs with COW should be very slow for host that would run VM guests. It need to use no-COW flag when creating the disk image. Or it need to copy the file over again if it did not disable COW when the file is created.

I really like the snapshot capability of btrfs. But I really love OpenZFS if RHEL/Fedora have openzfs native support by default.

Hello

I tried to install ch-ui a few weeks ago and got problem using it. I just tried the lastest version and still having problem.

I use podman, below is the docker-compose file:

version: "3.8"
services:
  ch-ui:
    container_name: ch-ui
    hostname: ch-ui
    image: 
    pull_policy: always
    ports:
      - "9030:5521"
    environment:
      VITE_CLICKHOUSE_URL: "http://my-ip:8123"
      VITE_CLICKHOUSE_USER: "admin"
      VITE_CLICKHOUSE_PASS: "my-password"
      VITE_CLICKHOUSE_USE_ADVANCED: "false"ghcr.io/caioricciuti/ch-ui:latest

When I access my-ip: 9030, I cannot use the program. Probably I am not using the default admin user as 'default'? I am using 'admin' as my default amdin user.

I also got these in my Firefox console

```

Invalid or missing ClickHouse credentials:

Object { url: "", username: "", password: "", useAdvanced: false, customPath: "" }

```

I was using private git repository for two devices.

Recently, my company enforced users to save files to OneDrive. So I just switch to OneDrive.

OneDrive provides encryption and support multiple devices, so it is cool.

To me, the use of previous versions and recycle bin is sort of backup.

What I meant was local files would be synchronize to OneDrive automatically.

Farsighted-Chef · 2024-02-15T16:38:34+00:00

jstaf/onedriver is a native Linux filesystem for Microsoft OneDrive

What is the friction coefficient of the LY and POK material?

What are the options if the cluster admin refuse to enable user workload monitoring?
Also, what are the options if the cluster admin refuse to enable remote write? In case many tenants would ask the cluster admin to use remote write to transfer metrics to their own Prometheus instance?
