HOSTCACHED
HOSTCACHED is a term used to describe a caching subsystem for host information within computer networks and distributed systems. It refers to mechanisms that store mappings between host identifiers (such as hostnames or service names) and associated data (for example IP addresses, port numbers, TLS certificates, or service endpoints) to accelerate subsequent lookups and reduce load on upstream name resolution services.
Operation and architecture: A HOSTCACHED module can run on individual nodes, in edge or gateway components,
Deployment and use cases: HOSTCACHED is used to speed up virtual machine and container orchestration, microservice
Benefits and challenges: The primary benefits are lower latency for name resolution, reduced DNS or directory
Relation to DNS and security: HOSTCACHED often complements DNS caching and service discovery mechanisms. Proper configuration
