eBPF is a technology built into the Linux kernel that allows for highly efficient and secure execution of custom code in kernel space. Service meshes, on the other hand, are software tools that control and monitor services within distributed applications. While eBPF and service meshes can be used together under the right circumstances, they also have distinct differences in terms of their architecture, functionality, and performance. The main advantages of using an eBPF-based service mesh include high efficiency and extensive control over service mesh operations, while the major disadvantages are limited support for nodes running older versions of Linux and fewer options available compared to traditional sidecar proxy models. A hybrid strategy can also be used, where eBPF programs handle certain service mesh functions and sidecar containers handle others. Additionally, groundcover offers built-in support for eBPF observability, making it a convenient choice regardless of the type of service mesh deployed. Ultimately, there is momentum in the service mesh world surrounding eBPF, and it's likely to play an increasingly important role in microservices management going forward.
