socketcluster - Highly scalable realtime framework

•    Javascript

SocketCluster is a fast, highly scalable HTTP + realtime server engine which lets you build multi-process realtime servers that make use of all CPU cores on a machine/instance. It removes the limitations of having to run your Node.js server as a single thread and makes your backend resilient by automatically recovering from worker crashes and aggregating errors into a central log on each host. SC can also auto-scale across multiple hosts on top of Kubernetes; see SCC guide: https://github.com/SocketCluster/socketcluster/blob/master/scc-guide.md.There are two ways to install SocketCluster.

Flynn is designed to run anything that can run on Linux, not just stateless web apps. Flynn comes with highly available database appliances, including PostgreSQL, MySQL, and MongoDB. Eventually we want Flynn to be the only tool developers and ops teams need to develop, deploy, and manage running software.

memcached - A fully featured Memcached client build on top of Node

•    Javascript

memcached is a fully featured Memcached client for Node.js. memcached is built with scaling, high availability and exceptional performance in mind. We use consistent hashing to store the data across different nodes. Consistent hashing is a scheme that provides a hash table functionality in a way that adding or removing a server node does not significantly change the mapping of the keys to server nodes. The algorithm that is used for consistent hashing is the same as libketama. There are different ways to handle errors for example, when a server becomes unavailable you can configure the client to see all requests to that server as cache misses until it goes up again. It's also possible to automatically remove the affected server from the consistent hashing algorithm or provide memcached with a failover server that can take the place of the unresponsive server.

yoke - Postgres high-availability cluster with auto-failover and automated cluster recovery.

•    Go

Yoke is a Postgres redundancy/auto-failover solution that provides a high-availability PostgreSQL cluster that's simple to manage. Note: The ini file can be named anything and reside anywhere. All Yoke needs is the /path/to/config.ini on startup.

infrakit - A toolkit for creating and managing declarative, self-healing infrastructure.

•    Go

InfraKit is a toolkit for infrastructure orchestration. With an emphasis on immutable infrastructure, it breaks down infrastructure automation and management processes into small, pluggable components. These components work together to actively ensure the infrastructure state matches the user's specifications. InfraKit therefore provides infrastructure support for higher-level container orchestration systems and can make your infrastructure self-managing and self-healing. In this video, InfraKit was used to build a custom linux operating system (based on linuxkit). We then deployed a cluster of virtual machine instances on a local Mac laptop using the Mac Xhyve hypervisor (HyperKit). A cluster of 3 servers booted up in seconds. Later, after the custom OS image has been updated with a new public key, InfraKit detects the change and orchestrates a rolling update of the nodes. We then deploy the same OS image to a bare-metal ARM server running on Packet.net, where the server uses custom ipxe boot directly from the localhost. It demonstrates some of the key concepts and components in InfraKit and shows how InfraKit can be used to implement an integrated workflow from custom OS image creation to cluster deployment and Day N management. The entire demo is published as a playbook, and you can create your own playbooks too.
