Apilator is a high-performance, self-contained clustered server for building data APIs over HTTP. Its components and algorithms have been carefully selected for high performance, and it is especially suitable for systems with a large number of low-activity clients, such as mobile or Web-based applications. It does not need an external application server, and features automated session cookies, automatically synchronised session storage across multiple instances, and unique dynamically adjusted session storage that gives you the flexibility to add or remove servers from the cluster without configuration or restarting.
LibreS3 is a robust open source implementation of the Amazon S3 service, supporting a subset of the S3 REST API. Standard S3 client libraries and tools (for example python-boto, s3cmd, DragonDisk, etc.) can be used to access it. LibreS3 uses Skylable SX as the storage backend, which automatically provides data deduplication and replication.
Apache UIMA DUCC (Distributed UIMA Cluster Computing) is a cluster management system providing tooling, management, and scheduling facilities that automate the scale-out of applications written using the UIMA framework. Core UIMA provides a generalized framework for applications that process unstructured information such as human language, but does not provide a scale-out mechanism. UIMA-AS extends UIMA and provides a scale-out mechanism for distributing UIMA pipelines over a cluster of computing resources, but does not provide job or cluster management of the resources. DUCC extends UIMA-AS by defining a formal job model that closely maps to a standard UIMA pipeline. Around this job model DUCC provides cluster management services to automate the scale-out of UIMA pipelines over computing clusters.
Hados stores files in a cluster of servers. Its goal is to handle high availability by storing copies of the same file on several nodes. It provides RESTFUL APIs to easily store, check, or retrieve files. Using the cluster APIs, you can retrieve files from whichever node hosts them. To avoid any single point of failure, it is possible to apply a request to any node of the cluster; there is no master node.
LavaFlow creates useful reports on the usage of high-performance computing clusters. It takes data from the batch scheduling system, monitoring, and other tooling, and creates reports which help administrators, managers, and end users better understand their cluster environment. The reports are modular, and new modules are easy to create using templates and Django's query set API. LavaFlow uses human-readable RESTful URLs, making it easy to automate and share links to reports.
JAConfig implements an eventually consistent distributed key/value database for managing a JASocket cluster. Also included are Quarum for tracking when a quorum of hosts is present, Ranker for determining which nodes are least loaded, ClusterManager for starting up other servers, and Kingmaker, which decides which node is to run ClusterManager. JAConfig is lock-free, actor-based, and has no single point of failure.
JASocket is a lock-free, scalable, and robust server framework with no single point of failure. Servers are run on a cluster of nodes. Servers interact with other servers using mobile agents, which reduces the number of messages and thus reduces the overall system latency. Administration is handled via ssh.
Collax V-Cube+ is a HA cluster management suite based on a 64bit Linux system and KVM to provide server virtualization. It offers solutions for single virtualization hosts, as well as high availability management on two or more nodes, allowing embedded HA storage using DRBD and iSCSI. By using live snapshots, automatic live migration, and incremental backups, the availability of virtual machines is increased tremendously in case of hardware and software maintenance or even hardware failures. Virtual network switches and the protocols GVRP, LLDP, and RSTP help to set up a virtual DMZ.
Nuxis is an integrated solution for virtualization management. Some of its features are centralized management of nodes/physical machines and virtual machines, management of virtual networks, storage management, ISO management, monitoring and statistics charts, backup/restore of appliance configurations, import from and export to other virtualization systems using the OVF format, access control, support for multiple operating systems on 32-bit and 64-bit architectures, including Linux and Windows, paravirtualized hardware acceleration drivers, live migrate, PXE boot, Web management, storage management with LVM, and more.
