Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of their customers. "Serverless" is a misnomer in the sense that servers are still used by cloud service providers to execute code for developers. However, developers of serverless applications are not concerned with capacity planning, configuration, management, maintenance, fault tolerance, or scaling of containers, VMs, or physical servers. Serverless computing does not hold resources in volatile memory; computing is rather done in short bursts with the results persisted to storage. When an app is not in use, there are no computing resources allocated to the app. Pricing is based on the actual amount of resources consumed by an application. It can be a form of utility computing.
Docker, Inc. is an American technology company that develops productivity tools built around Docker, which automates the deployment of code inside software containers. Major commercial products of the company are Docker Hub, a central repository of containers, Docker Desktop, a GUI application for Windows and Mac to manage containers.

eBPF is a technology that can run programs in a privileged context such as the operating system kernel. It is the successor to the Berkeley Packet Filter (BPF) filtering mechanism in Linux, and is also used in other parts of the Linux kernel as well.
Cilium is a cloud native technology for networking, observability, and security. It is based on the kernel technology eBPF, originally for better networking performance, and now leverages many additional features for different use cases. The core networking component has evolved from only providing a flat Layer 3 network for containers to including advanced networking features, like BGP and Service mesh, within a Kubernetes cluster, across multiple clusters, and connecting with the world outside Kubernetes. Hubble was created as the network observability component and Tetragon was later added for security observability and runtime enforcement. Cilium runs on Linux and is one of the first eBPF applications being ported to Microsoft Windows through the eBPF on Windows project.
