Problem Description

Sidecar proxies introduce significant overhead by adding extra complexity to the networking layer. If service A wants to communicate with service B, the message must pass through two sidecar proxies, like in the example below:
A --> Proxy A --> Proxy B --> B

Solution

By leveraging eBPF (Extended Berkeley Packet Filter), we can implement the networking layer directly at the kernel level, bypassing the user space and reducing the overhead introduced by sidecar proxies.
