HAProxy is a fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for web sites crawling under very high loads while needing persistence or Layer7 processing. Supporting tens of thousands of connections is clearly realistic with todays hardware.

VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems. So, for example, you can run Windows and Linux on your Mac. VirtualBox is a so-called hosted hypervisor. It requires an existing operating system to be installed. It can thus run alongside existing applications on that host. 

VirtualBox - Cross-Platform Virtualization Application

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder. It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set.

Gluster is a software defined distributed storage that can scale to several petabytes. It provides interfaces for object, block and file storage. It is a distributed scale-out filesystem that allows rapid provisioning of additional storage based on your storage consumption needs. It incorporates automatic failover as a primary feature. 
 
Gluster runs on top of most unix filesystems, with XFS and ext4 being the most popular choices. Data can be accessed from just about anywhere – You can use traditional NFS, SMB/CIFS for Windows clients, or our own native GlusterFS (a few additional packages are needed on the client machines for this, but as you will see, they are quite small).

xxHash is an Extremely fast Hash algorithm, running at RAM speed limits. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical on all platforms (little / big endian).Q.Score is a measure of quality of the hash function. It depends on successfully passing SMHasher test set. 10 is a perfect score. Algorithms with a score < 5 are not listed on this table.

xxHash - Extremely fast non-cryptographic hash algorithm
