Cilium is open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka. Cilium is integrated into common orchestration frameworks such as Kubernetes.
 
A new Linux kernel technology called eBPF is at the foundation of Cilium. It supports dynamic insertion of eBPF bytecode into the Linux kernel at various integration points such as: network IO, application sockets, and tracepoints to implement security, networking and visibility logic. eBPF is highly efficient and flexible.

age is a simple, modern and secure file encryption tool, format, and Go library. It features small explicit keys, no config options, and UNIX-style composability. It has support for public/private key pairs and passwords, with multiple recipients. An extremely simple CLI that composes well with UNIX pipes, and that works well as a backend for other programs. A good seekable streaming encryption scheme based on modern chunked AEADs, reusable as a general encryption format.

Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS). It replaces Postfix, Dovecot, OpenDKIM, OpenSPF, OpenDMARC and more with one daemon with uniform configuration and minimal maintenance cost.

Fiber is an Express inspired web framework built on top of Fasthttp, the fastest HTTP engine for Go. Designed to ease things up for fast development with zero memory allocation and performance in mind. New gophers that make the switch from Node.js to Go are dealing with a learning curve before they can start building their web applications or microservices. Fiber, as a web framework, was created with the idea of minimalism and follows the UNIX way, so that new gophers can quickly enter the world of Go with a warm and trusted welcome.

Micro is an operating system built for the cloud. It addresses the key requirements for building services in the cloud. It leverages the microservices architecture pattern and provides a set of services which act as the building blocks of a platform. Micro deals with the complexity of distributed systems and provides simpler programmable abstractions to build on.
 
Micro is built as a microservices architecture and abstracts away the complexity of the underlying infrastructure. It is composed as a single logical server to the user but decompose that into the various building block primitives that can be plugged into any underlying system.
The server is composed of the following services.<ul>
 <li>API - HTTP Gateway which dynamically maps http/json requests to RPC using path based resolution</li>
 <li>Auth - Authentication and authorization out of the box using jwt tokens and rule based access control.</li>
 <li>Broker - Ephemeral pubsub messaging for asynchronous communication and distributing notifications</li>
 <li>Config - Dynamic configuration and secrets management for service level config without the need to restart</li>
 <li>Events - Event streaming with ordered messaging, replay from offsets and persistent storage</li>
 <li>Network - Inter-service networking, isolation and routing plane for all internal request traffic</li>
 <li>Proxy - An identity aware proxy used for remote access and any external grpc request traffic</li>
 <li>Runtime - Service lifecycle and process management with support for source to running auto build</li>
 <li>Registry - Centralised service discovery and API endpoint explorer with feature rich metadata</li>
 <li>Store - Key-Value storage with TTL expiry and persistent crud to keep microservices stateless</li></ul>

Dapr is a portable, serverless, event-driven runtime that makes it easy for developers to build resilient, stateless and stateful microservices that run on the cloud and edge and embraces the diversity of languages and developer frameworks. Dapr codifies the best practices for building microservice applications into open, independent, building blocks that enable you to build portable applications with the language and framework of your choice. Each building block is independent and you can use one, some, or all of them in your application.

Fission is a fast serverless framework for Kubernetes with a focus on developer productivity and high performance.Fission operates on just the code: Docker and Kubernetes are abstracted away under normal operation, though you can use both to extend Fission if you want to.
 
Fission is extensible to any language; the core is written in Go, and language-specific parts are isolated in something called environments (more below). Fission currently supports NodeJS, Python, Ruby, Go, PHP, Bash, and any Linux executable, with more languages coming soon.
 
Fission Concepts 
A function is a piece of code that follows the fission function interface. An environment contains the language- and runtime-specific parts of running a function. A trigger is something that maps an event to a function; Fission supports HTTP routes as triggers today, with upcoming support for other types of event triggers, such as timers and Kubernetes events.

Gitpod is an open-source Kubernetes application for ready-to-code developer environments that spins up fresh, automated dev environments for each task, in the cloud, in seconds. It enables you to describe your dev environment as code and start instant, remote and cloud-based developer environments directly from your browser or your Desktop IDE.
 
Gitpod continuously builds your git branches like a CI server so that you can start coding right away - no more waiting for dependencies to download and builds to finish. Tightly integrated with GitLab, GitHub, and Bitbucket, Gitpod automatically and continuously prebuilds dev environments for all your branches. As a result, team members can instantly start coding with fresh, ephemeral and fully-compiled dev environments - no matter if you are building a new feature, want to fix a bug or do a code review.
