Redundancy is a form of resilience that ensures system availability in the event of component failure. Components (N) have at least one independent backup component (+1).The level of resilience is referred to as active/passive or standby as backup components do not actively participate within the system during normal operation.
In addition to this, an OpenShift-native pod builds technology called Source-to-Image (S2I) is available out of the box, though this is slowly being phased out in favor of Tekton — which is a cloud native way of building and deploying to Kubernetes. For the OpenShift platform, this provides capabilities equivalent to what Jenkins can do.
2 node High Availability Cluster network diagram. The most common size for an HA cluster is a two-node cluster, since that is the minimum required to provide redundancy, but many clusters consist of many more, sometimes dozens of nodes.
When the master unit fails, an automatic failover to the hot spare occurs within a very short time and the outputs from the hot spare, now the master unit, are delivered to the controlled devices and displays. The controlled devices and displays may experience a short blip or disturbance during the failover time.
The term "failover", although probably in use by engineers much earlier, can be found in a 1962 declassified NASA report. [2] The term "switchover" can be found in the 1950s [3] when describing '"Hot" and "Cold" Standby Systems', with the current meaning of immediate switchover to a running system (hot) and delayed switchover to a system that needs starting (cold).
NASA's Nebula platform. In July 2010, Rackspace Hosting and NASA announced an open-source cloud-software initiative known as OpenStack. [7] [8] The mission statement was "to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable".
Litening is an integrated targeting pod that mounts externally to the aircraft. The targeting pod contains a high-resolution, forward-looking infrared (FLIR) sensor that displays an infrared image of the target to the aircrew; it has a wide field of view search capability and a narrow field of view acquisition/targeting capability of battlefield-sized targets.
