7 Open Source Cloud Native Tools That Aren’t Kubernetes

Seven puppies laying in the sun

1. Nomad

Did you know there are container orchestrators besides Kubernetes? One of them is Nomad, made by the folks at HashiCorp.

2. Pulumi

I spent some years pretty deep in the Infrastructure as Code world (I worked as an SRE at Puppet and was a Puppet user before that), and it’s a topic that still interests me quite a bit. For a while I thought Terraform had won the cloud provisioning tools space, and maybe it still has, but Pulumi is a newer alternative with some pretty cool aspects.

3. Thanos

Everyone loves them some Prometheus, am I right? It’s definitely one of the most popular observability tools for working with Kubernetes and other cloud native apps. But how do you set up Prometheus so it’s highly available and scalable? And how do you deal with all the data?

  • Each subcommand should do one thing and do it well
  • Write components that work together
  • Make it easy to read, write, and, run components

4. etcd

I can already hear someone saying, “Wait, I thought this list wasn’t about Kubernetes, so why is etcd on it?” Well, while etcd is best known as the data store for Kubernetes clusters, you can do a lot more with it.

5. Kuma

Remember virtual machines? Those were good times, right? It turns out that a lot of people are still using them, and teams that are not running containerized workloads have had a tougher time using service meshes like Istio and Linkerd.

6. Sigstore

If you follow me on Twitter or saw my previous post about companies I’m watching in 2022, you probably already know that I’m a bit of a sigstore fanboy. But for those of you who haven’t heard me rant about it, here’s why.

7. OpenTelemetry

OpenTelemetry is a standard for distributed tracing that was created when the OpenTracing and OpenCensus projects merged. That merger reduced a lot of confusion in the tracing space, and OpenTelemetry has since been adopted by major vendors like Honeycomb, Datadog, New Relic, and Dynatrace.


There are many more exciting cloud native tools out there. When I create lists like this, there are almost always folks who have ideas for other tools that I should have included. If you have a tool that you’d like to mention, feel free to join the discussion on Reddit, or send me a tweet.
