Regarding the flexibility part, if I want to use something such as Kong/Linkerd service mesh or other solutions, most of the CSPs bind you to their own solutions rather than allow other options to be made and integrated with, and this is what I mostly miss in their part. In terms of built-in observability in Amazon EKS, I know it's mostly about the great integration with AWS itself. When I want to integrate it with any Grafana or Prometheus solution within AWS, things work efficiently with IAM. However, when I want to cross the boundary of the CSP, that becomes an issue. Integrating some open-source solutions works, but I need to work really hard for that. The major area for improvement I've seen involves deep diving into one CSP with no equivalent solution elsewhere. The most important consideration is about the pricing and the flexibility of moving and building a multi-cloud environment for most customers. The issue is that when CSPs try to lock you in, flexibility becomes the most critical aspect. Amazon aims to put you in a very Amazon-centric environment, but you need to be aware when you're using Amazon EKS that you're not locked in. The major paradigm for customers with maturity in using cloud solutions is to avoid vendor lock-in. Most early adopters understand this, but the main mass, such as the banking companies I work with, aren't in the same state of mind; they need to build everything from a Cloud Native perspective with as much OSS as possible.
