Open vSwitch is well suited to function as a virtual switch in VM environments. In addition to exposing standard control and visibility interfaces to the virtual networking layer, it was designed to support distribution across multiple physical servers. Open vSwitch supports multiple Linux-based virtualization technologies including Xen/XenServer, KVM, and VirtualBox.

Open vSwitch - Multilayer Virtual Switch

Firecracker is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services that provide serverless operational models. Firecracker runs workloads in lightweight virtual machines, called microVMs, which combine the security and isolation properties provided by hardware virtualization technology with the speed and flexibility of containers.
 
The main component of Firecracker is a virtual machine monitor (VMM) that uses the Linux Kernel Virtual Machine (KVM) to create and run microVMs. Firecracker has a minimalist design. It excludes unnecessary devices and guest-facing functionality to reduce the memory footprint and attack surface area of each microVM. This improves security, decreases the startup time, and increases hardware utilization.
 
Firecracker was developed at Amazon Web Services to accelerate the speed and efficiency of services like AWS Lambda and AWS Fargate.

OpenSwitch provides an abstraction of hardware devices of network switch platforms in a Linux OS environment. It uses standard open source software including an ONIE installer, and an unmodified Linux kernel based on Debian Jessie distribution. It provides an object-centric API for application development to implement custom applications using a well-defined object model, and set of programmatic APIs.
 
OPX Base software supports hardware virtualization (or simulation). Software simulation of basic hardware functionality is also provided (“white board”), and the higher layer software functionality can be developed and tested on generic PC/server hardware.

Helix is a generic cluster management framework used for the automatic management of partitioned, replicated and distributed resources hosted on a cluster of nodes. It helps to perform scheduling of maintenance tasks, such as backups, garbage collection, file consolidation, index rebuilds, repartitioning of data or resources across the cluster, informing dependent systems of changes so they can react appropriately to cluster changes, throttling system tasks and changes and so on.
