In a cargo ship, the bulkhead is a wall built between different cargo sections, which makes sure that a fire or flood in one section is restricted to that section and other sections are not impacted. You've surely guessed what we are trying to suggest: failure in one service or a group of services should not bring down the whole application.

To implement the bulkhead pattern, we need to make sure that all our services work independently of each other and failure in one will not create a failure in another service. Techniques such as maintaining a single-responsibility pattern, an asynchronous-communication pattern, or fail-fast and failure-handling patterns help us to achieve ...
