Ambassador Edge Stack, a Kubernetes-native API Gateway, provides simplicity, security, and scalability for some of the largest Kubernetes infrastructures in the world. Ambassador Edge Stack makes it easy to secure microservices with a complete set of security functionality including automatic TLS, authentication and rate limiting. WAF integration is also available. Fine-grained access control is also possible. The API Gateway is a Kubernetes-based ingress controller that supports a wide range of protocols, including gRPC, gRPC Web, TLS termination, and traffic management controls to ensure resource availability.

Flux is an open and extensible suite of continuous and progressive delivery solutions designed for Kubernetes. The newest iteration of Flux introduces numerous enhancements that increase its flexibility and adaptability. As a project incubated by the CNCF, Flux, along with Flagger, facilitates application deployments utilizing strategies such as canaries, feature flags, and A/B rollouts. It possesses the capability to manage any Kubernetes resource seamlessly. Built-in features allow for effective infrastructure and workload dependency management. Through automatic reconciliation, Flux enables continuous deployment (CD) and, with Flagger's assistance, supports progressive delivery (PD). Additionally, Flux can automate updates by pushing changes back to Git, including container image updates through image scanning and patching processes. It integrates smoothly with various Git providers, including GitHub, GitLab, and Bitbucket, and can also utilize s3-compatible buckets as a source. Furthermore, it is compatible with all major container registries and CI workflow providers. With support for Kustomize, Helm, RBAC, and policy-driven validation mechanisms such as OPA, Kyverno, and admission controllers, Flux ensures that deployment processes are streamlined and efficient. This combination of features not only simplifies management but also enhances operational reliability in Kubernetes environments.
