In the cloud, it becomes natural to use immutable environments by defining your infrastructure as code and re-creating your entire workload stack from scratch for every deployment. In this case, mutable environments are the exception more than the rule, and one tends to forget about patching. Further, it is also very natural to use managed services, which often take care of the patching on your behalf, especially when such services are serverless and you have little to no control over the supporting infrastructure.

However, the fact is that patching is as important for immutable environments as it is for mutable environments, and it is also super important for managed services for which...
