First, let’s take a quick look at the complicated nature of lock-in versus lock out. Vendor lock-In occurs when a company gets stuck relying on a specific technology or service from a particular cloud provider. This makes it difficult and expensive to switch providers or technologies. It’s a bit of a trap when you become too dependent on one company. On the other hand, vendor lock-out happens if a company loses access to its data or services supplied by a cloud provider. It can happen if ...| Veeam Software Official Blog

If you have heard anything about service meshes, it is that they work using the sidecar pattern: a proxy server is deployed alongside your application code. The sidecar pattern is just that: a pattern. Up until this point, there has been no formal support for sidecar containers in Kubernetes at all. This has caused a number of problems: what if you have a job that terminates by design, but a sidecar container that doesn’t?
