The first bullet of How to Prevent is "Use container-based solutions that make it easy to limit memory, CPU, ...". Containers is only one way of achieving limits, you could also use serverless technology such as Lambdas (even virtualisation / managed services on cloud allows us to limit these aspects too).

Therefore would recommend slight wording order shift to "Use a solution that makes it easy to limit memory, CPU ..., such as Containers / Serverless code)." This way the guidance has a wider coverage and not bound to a particular implementation approach / technology.
