BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.

OpenMAMA Project provides a vendor neutral integration layer for a variety of message oriented middleware systems and messaging protocols. It enables an application to employ a range or middleware systems simultaneously or switch between them at will while developing with a single open source API. Adding or changing the messaging stack does not require lengthy and expensive code changes. 
 
In addition to providing a single API for messaging, OpenMAMA implements a number of advanced features that simplify writing many messaging applications including those that consume financial market data.

FSArchiver is a system tool that allows you to save the contents of a file-system to a compressed archive file. The file-system can be restored on a partition which has a different size and it can be restored on a different file-system. Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive.

DPDK is a set of libraries and drivers for fast packet processing. It was designed to run on any processors. The first supported CPU was Intel x86 and it is now extended to IBM Power 8, EZchip TILE-Gx and ARM. These libraries can be used to  receive and send packets within the minimum number of CPU cycles (usually less than 80 cycles), develop fast packet capture algorithms (tcpdump-like) and run third-party fast path stacks.

Galera cluster provides distributed, multi master support for MySQL and MariaDB. Its feature include Synchronous Replication, True Multi-master, Active-Active Cluster Read and write to any node at any time, Automatic Node Provisioning, Multi-threaded Slave and lot more. 
 
Galera Cluster is a superb replication system when using MySQL or MariaDB for your databases. However, it does have some limits for which you may want to be aware before migrating to it. Within the database server, other than the system tables, which use MyISAM, only InnoDB tables are allowed. InnoDB is used because it’s an excellent transactional storage engine. All tables must have an explicit primary key, either a single or a multi-column index.
