software resiliency patterns

The fundamental goal of software resiliency patterns is to build systems that anticipate and tolerate failures while continuing to provide an acceptable level of service.

resiliency - устойчивость anticipate - предвидеть tolerate - терпеть, выносить

Bulkhead pattern

you divide into discrete sections your application's resources so that failure of any one of your dependencies is not cascaded into the entire system

The bulkhead pattern is a design strategy that isolates components of a system into separate resource pools to prevent a failure in one part from cascading and affecting the entire application.

Event Sourcing Pattern

Event Sourcing Pattern stores all changes to application state as a sequence of events rather than only saving the current state.

consumer-driven contract (CDC)

A consumer-driven contract (CDC) in microservices is a testing method where consumers define the expectations they have of a service provider's API, and providers use these consumer expectations to verify that they won't break compatibility.

Polyglot persistence

Polyglot persistence in microservices is the practice of using different data storage technologies for different services to match specific needs, such as relational databases for transactional data, key-value stores for caching, and document databases for flexible data structures.
