Prometheus is a free software application used for event monitoring and alerting. [2] It records metrics in a time series database (allowing for high dimensionality) built using an HTTP pull model, with flexible queries and real-time alerting.
Historically Kubernetes was suitable only for stateless services. However, many applications have a database, which requires persistence, which leads to the creation of persistent storage for Kubernetes. Implementing persistent storage for containers is one of the top challenges of Kubernetes administrators, DevOps and cloud engineers.
Checkmk is a software system developed in Python and C++ for IT Infrastructure monitoring. It is used for the monitoring of servers, applications, networks, cloud infrastructures (public, private, hybrid), containers, storage, databases and environment sensors.
Programs have to transfer data to and from storage devices and have to provide mappings from the native programming-language data structures to the storage device data structures. [ 1 ] [ 2 ] Picture editing programs or word processors , for example, achieve state persistence by saving their documents to files .
Ceph (pronounced / ˈ s ɛ f /) is a free and open-source software-defined storage platform that provides object storage, [7] block storage, and file storage built on a common distributed cluster foundation.
The read-of-non-persistent-write problem is found for lock-free programs on persistent memory. As compare-and-swap (CAS) operations do not persist the written values to persistent memory, the modified data can be made visible by the cache coherence protocol to a concurrent observer before the modified data can be observed by a crash observer at persistent memory.
Persistent data in the field of data processing denotes information that is infrequently accessed and unlikely to be modified. [ 1 ] Static data is information, for example a record , that does not change and may be intended to be permanent.
Polyglot persistence shares its origins with how the term polyglot programming is defined. Polyglot programming is a term coined by Neal Ford in 2006, and expresses the idea that computer applications should be written in a mix of different programming languages, in order to take advantage of the fact that different languages are suitable for tackling different problems.
