The presentation discusses the need for a lighter and more efficient way to manage microservices in the post-pandemic rise of lightweight microservices. The solution presented is the use of WebAssembly System Interface (WASI) to create a more lightweight and efficient infrastructure.
- The rise of lightweight microservices has created a need for a more efficient way to manage them
- Current technology is not efficient enough for the large number of microservices required by modern applications
- WebAssembly System Interface (WASI) provides a more lightweight and efficient infrastructure for managing microservices
- WASI enables non-blocking sockets, supports domain name lookup, and extends the current API to allow for more functionality
- WASI can be integrated with various databases and frameworks, including MySQL, Maria DB, PostgreSQL, and Redis server
- The use of WASI can lead to a more efficient and lightweight infrastructure for managing microservices

The Kubernetes API provides a gateway to manage cloud native resources, and there exist client libraries to interact with Kubernetes in many languages. Rust is uniquely positioned to write software for Kubernetes. With a powerful type system, fast binaries, excellent documentation, and unparalleled memory safety it is well positioned for critical tooling and infrastructure. This talk will be a crash course on how to interact with Kubernetes in Rust, and will cover the basics you need to know to write your next tool targeting Kubernetes with Rust.

As CRI-O approaches CNCF graduation, it continues in its mission to provide a stable and secure OCI implementation of the Kubernetes CRI. Join the CRI-O team as they give an overview of CRI-O as well as talk about some new work, such as the progress on the new container monitor conmon-rs, rewritten completely in Rust. The team will also talk about the integration with sigstore to secure CRI-O’s supply chain as well as some of the interesting work being done in CRI-O to stay in-line with upstream Kubernetes. These include the stats collection rework as well as the work to support evented PLEG. Audience members will leave with an understanding of what CRI-O is, and where it is going.

After five years as a CNCF project, containerd is still actively growing in contributors and maintainers who are busy working on interesting features and capabilities in the core and non-core containerd projects. During this project update from maintainers you'll learn about the latest work in containerd, including our recent addition of sandboxes, a handful of CRI and CNI improvements, as well as various improvements to the architecture and services that drive containerd's use by other projects and platforms. Outside of the core containerd project, our "non-core" projects have grown in number, including several Rust-based projects, new snapshotter implementations, and the increasingly popular client-focused project, nerdctl. Come join us for a fast-paced update on all these areas and to ask your containerd questions with the handful of on-site containerd maintainers.

Dapr is a very popular sidecar-based application framework that supports microservices written in many languages. WasmEdge is a cloud-native WebAssembly runtime. It provides the necessary networking APIs to support WebAssembly-based microservices. In this talk, I will demonstrate how to create Rust and JavaScript functions, and run them as Dapr microservices through the WasmEdge runtime. I will also cover more advanced topics such as how to interact with Dapr APIs from the WebAssembly function and how to manage the WadmEdge microservices using Kubernetes. Source code and a live example are available here: https://github.com/second-state/dapr-wasm

TiKV has introduced new features to improve its service quality in cloud storage, including Raft Engine and Prioritized I/O Rate Limiting.
- TiKV is a distributed storage engine that can scale out to hundreds of nodes and replicate both wall and data files to provide high availability.
- Cloud storage hardware can be a challenge due to its internal complexity, higher latency, and shared hardware with other users.
- To reduce cost and improve scalability, TiKV has introduced two new features: Raft Engine and Prioritized I/O Rate Limiting.
- Raft Engine is a new log store for TiKV that maintains an email index of all log entries, reducing background works and compressing log entries with lz4 to reduce nearly 30% of all server writes.
- Prioritized I/O Rate Limiting categorizes all system I/Os into three different priorities and assigns individual I/O limits to those priorities, adjusting the I/O limits for lower priorities after an overflow to decrease the global I/O usage of the system.

Overview of Linkerd project and its features for Kubernetes service mesh
- Linkerd is a service mesh for Kubernetes that provides observability, reliability, and security
- Observability is achieved through sidecar proxies that monitor http, grpc, and tcp metrics
- Reliability features include grpc load balancing, connection level load balancing for tcp, and configurable retries and timeouts
- Security is provided through transparent mtls for pod-to-pod communication
