The Omni Team's goal it to solve the multi-cluster multi-cloud Kubernetes challenge! Building on top of concepts from cluster federation it tries to shift the paradigm in Kubernetes usage patterns and how it is being used when many clouds are involved. And while doing this to enable CAST AI customers to realize significant AAA savings for our customers.
To give you a glimpse into the complexities we navigate:
We’ve successfully proven that you can do more with Kubernetes compute resources in the ways people didn't think was possible. We are building on top of giants, by leveraging OpenSource technologies like wireguard and controller-runtime. We write custom Kubernetes operators to orchestrate every component, related to multi-cluster operations in the clusters. Manage OpenSource project usage by maintaining stability, security, flexibility and independence. We strive for minimal APIs and user experience with the goal to make multi-cloud not only a buzzword, but reality. We're breaking new grounds of networking, Kubernetes operators and cloud provisioning at CAST AI. The above examples merely scratch the surface of what we've achieved. Consider that these efforts are magnified by the range of cloud providers we support - and each one presents its own unique challenges. Each development sprint uncovers new hurdles and learning opportunities. We consider ourselves fortunate to operate in a cutting edge technological landscape.
Here are some of the technologies we use in the stack: GoLang is our language. Kubernetes is our core product. AWS, GCP, and Azure are the clouds we operate. Postgres and cloud object storage for persistence. Temporal for our scheduling needs and executor. VirtualKubelet and ControllerRuntime for our operators stack. Terraform for IaC. GCP PubSub for messaging. GRPC and REST APIs. We use GitLab CI with ArgoCD as our GitOps CD engine. Prometheus, Grafana, Loki, and Tempo for observability. Deployment charts are written in Helm. Having experience with these tools is not a strict prerequisite for the ideal candidate, but it does offer a competitive edge.
