Continuous Integration (CI), Continuous Testing (CT), and Continuous Delivery (CD) are considered to be the key metrics to measure successful DevOps practice.

CT is considered to be the first step in the right direction when embarking on a DevOps journey. It is a continuous feedback mechanism that drives software delivery through SDLC. If the automated feedback at each checkpoint indicated no bugs or issues, then the process automatically moves to the next step in the delivery chain.

Simple on-prem alternative to AWS for a solo-developer?

I am a developer and I am quite experienced working with AWS. I've been using a broad range of AWS services and I've been very pleased with being able to just use the AWS console and find my way around without sweating much.

Now I need to work on a project that needs to be working on premise bare metal servers. I'd I am decent software developer but my devops skills are pretty lacking. I've been looking at Kubernates, Terraform, Nomad, OpenShift, Docker swarm... Honestly, it's too complicated for me. I guess, it would make sense if you are working on projects where you need to manage tens/hundreds/thousdands? of apps/servers with a team of people. But's it simply feels like an overkill in my case.

From a solo developer perspective, what could be a simple alternative to AWS?
Basically, I need:

\- RDS (Mysql or Postgres with easy to use, automated backups etc.)
\- Elastic Beanstalk (deploying and scaling applications)
\- CloudWatch for dashboards, monitoring metrics, logs and events
\- S3 like object store (no need to be as fancy as S3)
\- And hopefully just a GUI to manage these all.

What direction can look for?

Getting Better With Kubernetes

I've been working on devops for a number of years, but my experience with Kubernetes has been minimal.

Does any one have any suggestions on where I can learn more about Kubernetes? I really think I should just start at the basics and work up.

Just reading docs isn't super effective for me. I'm much better at learning by following asking with examples and reproducing those examples myself, so something with some hands on kind of learning would be great.

Thanks all!

Gauging value for system monitoring

Consider you have started a new project or perhaps your are inheriting a legacy system that has little to no structure or documentation (or so it would seem).

What practices or approaches do you use to collect, gauge and track the important metrics your system produces?

I have been reviewing Wardley mapping as a way of exposing the needs of the systems users, feeding these back to be used as the focus for SLOs.

The DevOps Institute - Certifications

Does anybody have any thoughts on whether these certifications have any value?

We have a manager pushing us to get DevOps Foundation and Leader certificates.

https://devopsinstitute.com/certifications/devops-foundation/

Do they have much credibility? Personally I have never seen any potential employer asking for them. Will it have any practical or professional value or will it just be a meaningless piece of paper?

GitOps for KubeVirt?

Is there a GitOps style operator for KubeVirt kinda like Argo?

​

I've had pretty good success running Argo, but I need to spin up a Windows VM in one of my clusters (ugh) and would prefer to do it IaC style. Any tips/tricks?

​

Thanks!

Packer for usb bootable iso

New enough to packer that I'm not sure if making an ISO that's not for vagrant/docker/vm is weird.

When I look at packer Ubuntu "builders" like https://github.com/chef/bento/blob/master/packer\_templates/ubuntu/ubuntu-20.04-amd64.json

Other than changing my user name or leaving it as vagrant is there any reason this won't work?

Enterprise equivalent of a software distribution platform like Steam?

Bit of an odd question but I've recently gotten a job in the academic space due to my experience in game development. Their goal is to distribute the software I'll be working on to clients but with all the features Steam has for this such as:

* Automatically uploading builds that pass all tests to the platform.
* Automatic updates for the software.
* Ability to distribute "DLC" to those that qualify to get it.
* Incremental updates (if one line in a 500MB file is changed, just send that line)
* Update compression to reduce bandwidth
* Ability to quickly rollback to a previous version
* Ability to have multiple branches for betas

From a game dev background I take all of these features of Steam for granted. My question now is how do I accomplish this without Steam? Are there off the shelf alternatives for this? I don't really know what to put into Google for this question so I need a bit of direction.

How do your developers claim databases?

The literature for proper design of microservices has taught developers that each of their microservices should have its own, isolated database and state. This of course allows these services to be decoupled from one another ensuring that they each can grow and evolve autonomously.

While this architecture has a lot of benefits for developer and service autonomy, it also means that developers frequently need to provision or request new databases that fit their requirements. Furthermore, these requests need to be made in duplicate, triplicate or more, to accommodate different application environments like QA, dev, staging, prod, and that doesn't even begin to include private developer environments. With so many databases being provisioned to power a growing application, teams very quickly have to figure out the answers to questions like:

* who is allowed to access the cloud provider and create database instances?
* who is responsible for ensuring this database is always up and running and is a suitable size for the growing application?
* what process should developers follow to securely connect to the database from their applications?
* where should database credentials be stored?
* how do I ensure that the data is stored in accordance with local regulations?

These questions are important, but who are they important to? In most cases, all the the person who needs the database (the developer) cares about is, "I need a database of type `X` that supports features in version `Y`". Replace `X` with your favorite database type (e.g. PostgreSQL, MySQL, MongoDB, etc.) and `Y` with the version of that database type, and that should be enough for the initial request to be fulfilled. Most of the other questions on the list are best answered by SREs or other production engineering roles better equipped for them.

-----

Now for my question: what (if anything) is your company doing to make it easier for developers to provision and/or request databases or schemas to power their services and apps? Do they log into your cloud provider themselves and make instances? Do they file tickets with the SREs? Do they create CloudFormation or Terraform templates directly? Is there a team that creates and manages a central repo of shared Terraform modules? Or perhaps are you doing something else entirely?

My team and I are trying to build a framework that allows developers to more easily request private database schemas, and I'd love to find out what others are doing so I can make sure we build it to account for all cases. What we want at the end of it is for developers to declare the database type and version they need and for our deployment engine to automatically fulfill it. Fulfillment right now would do the following:

1. match the request against an existing instance in the environment or (possibly) provision a new one,
2. create a private schema for the requesting app or service
3. create a unique role for the requesting service to access the schema,
4. automatically inject the schema and credentials into the requesting service, and finally
5. whitelist network traffic from the requesting service to the database instance

Here's a brief snapshot of what a developer might declare to describe their service's database needs:

```yaml
databases:
user-data: postgres:13
cache: redis:6

services:
api:
build:
context: .
interfaces:
http: 8080
environment:
DB_URI: ${{ databases.user-data.url }} # postgres://<user>:<pass>@<host>:<port>/<db_name>
# Alternatively you can access each part of the connection URI directly
DB_USER: ${{ databases.user-data.user }}
DB_PASS: ${{ databases.user-data.pass }}
DB_HOST: ${{ databases.user-data.host }}
DB_PORT: ${{ databases.user-data.port }}
DB_NAME: ${{ databases.user-data.database }}
CACHE_URI: ${{ databases.cache.url }} # redis://user:pass@host:port/db_index
```

If you've read this far, I have two more questions for you: 1) what other features might be worth exposing to a developer, and 2)

what other key configuration details might be missing that I haven't mentioned yet? I believe this to be a separation of duties problem, and want to make sure both developer and operator concerns can be accounted for.

Thanks in advance!

Prometheus Grafana vs EFK stack

Hi there,

I am doing research on comparative analysis between prometheus-Grafana and efk (elastic, fluentd and Kibana) stack, but since efk is a distributed stack of different technologies, there aren't many direct comparison available on internet. Anyone have any reference which gives the detailed comparison between the two stack or any leads from your personal experiences will help ?

Ideal to have some pointers on better performance and resource utilization ?

Thanks
