i-doit is a web based IT documentation and CMDB. i-doit documents IT-systems and their changes, defines emergency plans, displays vital information and helps to ensure a stable and efficient IT operation: The technical documentation: This means that all information can be organised (details flexibly adjusted), stored and maintained in one place. This allows simple Helpdesk, Support and Planning functions and provides the basis for quality assurance and certification. i-doit allows services to be documented as a logical grouping of objects placed in relation to each other. This provides the basis for (ITIL) processes such as Change and Problem Management, helps to control and manage the SLA (Service Level Agreement) or the communication with users. Its interfaces to other ITSM applications (like Nagios, Request Tracker etc.) allow the entering of data only once in the ITSM environment. i-doit maintains one holistic view of the operational situation.

Redis is an open-source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams. Redis has built-in replication, Lua scripting, LRU eviction, transactions, and different levels of on-disk persistence, and provides high availability via Redis Sentinel and automatic partitioning with Redis Cluster. You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing an element to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set. To achieve top performance, Redis works with an in-memory dataset. Depending on your use case, you can persist your data either by periodically dumping the dataset to disk or by appending each command to a disk-based log.
