The packaging of software code with just the operating system (OS) libraries and dependencies required to run the code to create a single lightweight executable.
Containerisation (e.g., Docker) bundles an application with all its dependencies, libraries, configuration files, and frameworks, into a single "container." This ensures that the software runs exactly the same way on a developer's laptop, a testing server, and the production cloud.
Containerisation is why modern web apps crash less often and deploy features faster. It is the supply chain logistics of the software world.

Cold Start
The initial latency when a serverless function or container starts up after being idle, affecting response times.
Edge Computing
Processing data closer to users at network edges rather than centralised data centres, reducing latency.
Error Budget
