bpftime: Userspace eBPF Runtime for Network and Observability
eBPF has significantly advanced networking and monitoring. However, its in-kernel execution, while stable and easy to deploy, limits performance compared to userspace alternatives like DPDK for network functions and userspace instrumentation for Uprobe. This session introduces bpftime, a userspace eBPF runtime designed for network functions and observability tools. bpftime allows existing eBPF control applications to operate in unprivileged userspace, offering Uprobe, syscall tracepoints, and XDP hooks with improved performance. It supports interprocess eBPF maps in userspace shared memory and can work with kernel eBPF maps, providing seamless integration and compatibility with the kernel's eBPF infrastructure.
eBPF: a new era in cloud infrastructure tools
eBPF has become something of a buzzword recently, but why is it being used in so many tools for observability, security and networking? What does it bring that other approaches don't offer? How can you leverage the power of eBPF in your organization?
Join this session to learn from the creators and maintainers of leading open source eBPF projects about how this kernel technology enables high-performance, scalable cloud infrastructure tools.
eBPF + Wasm: lightweight observability on steroids
eBPF is a great tool for network traffic management and observation in a service cluster. However, the current tooling to deploy eBPF programs and agents often requires its own VM or containers in a k8s cluster, and this heavy infrastructure defeats the lightweight benefits of eBPF.
Wasm, on the other hand, has become a lightweight alternative “container” for the k8s ecosystem. It is now possible to create Wasm-based eBPF control plane applications that manage eBPF agents in k8s pods.
In this talk, we will discuss the eBPF plugin from the WasmEdge community (a CNCF sandbox project). It allows lightweight WasmEdge sandboxes managed by container tools such as containerd, crun, Docker, and Podman, to deploy and control eBPF applications in k8s clusters. We will discuss the mechanism that enables the eBPF plugin in WasmEdge, as well as developer APIs and tools for building eBPF applications.
