Why Nx Cloud?

If CI feels challenging to you, it might not be your fault. It's a fundamental issue with how the current, traditional CI execution model works. Nx Cloud adopts a new task-based CI model which allows you to overcome both the slowness and unreliability of the current VM-based CI model. (Dive deeper into the task based CI execution model on our blog post at https://blog.nrwl.io/reliable-ci-a-new-execution-model-fixing-both-flakiness-and-slowness-6849fd4b4037 ")

Nx Cloud addresses critical aspects of CI/CD, including:

• speed - 30% - 70% faster CI (based on reports from our clients)
• cost - 40% - 75% reduction in CI costs (observed on the Nx OSS monorepo)
• reliability - by automatically identifying flaky tasks (e2e tests in particular) and re-running them

How?

Nx Cloud follows a task-based CI model which is not just fast but also robust. Instead of statically assigning work to machines (as in a traditional CI model), you can imagine a pile of tasks which get picked up automatically by agents on the Nx Cloud infrastructure. There's no static assignment, agents coordinate the work by themselves. If an agent fails during the setup phase, other agents will pick up its work. If more work needs to be done, more agents will be started to still guarantee a fast execution, if less work is needed, fewer agents will be started to save resources.

All this is possible because Nx Cloud directly integrates with Nx and has knowledge about the project structure and tasks as well as dependencies among them.
