Apache Dubbo vs Flux CD: What are the differences?

Developers describe Apache Dubbo as "A high performance Java RPC framework". It is a high-performance, light weight, java based RPC framework. Dubbo offers three key functionalities, which include interface based remote call, fault tolerance & load balancing, and automatic service registration & discovery. On the other hand, Flux CD is detailed as "The GitOps operator for Kubernetes". It is a tool that automatically ensures that the state of your Kubernetes cluster matches the configuration you’ve supplied in Git. It uses an operator in the cluster to trigger deployments inside Kubernetes, which means that you don’t need a separate continuous delivery tool.

Apache Dubbo belongs to "Remote Procedure Call (RPC)" category of the tech stack, while Flux CD can be primarily classified under "Container Tools".

Some of the features offered by Apache Dubbo are:

• Transparent interface based RPC
• Intelligent load balancing
• Automatic service registration and discovery

On the other hand, Flux CD provides the following key features:

• Describe the entire desired state of your system in Git. This includes apps, configuration, dashboards, monitoring, and everything else
• Use YAML to enforce conformance to the declared system. You don’t need to run kubectl because all changes go through Git. Use diffing tools to detect divergence between observed and desired state and receive notifications
• Everything is controlled through pull requests, which means no learning curve for new developers. Just use your standard PR process. Your Git history provides a sequence of transactions, allowing you to recover system state from any snapshot. Fix a production issue via pull request rather than making changes to the running system
