Alternatives to Amazon ECR

We have been using Docker Hub free plan for some time, which had automated builds feature included in the free plan. Recently it has been removed from the free plan. Therefore we have thought to either go ahead with a paid plan of Docker Hub, which includes automated builds feature or migrate to use Amazon ECR as the container registry management solution. Since we already use some AWS services, going ahead with Amazon ECR is a viable solution. I am a bit confused as to what would be the best choice going ahead. Please advice...!

Which one to choose Docker Hub or Harbor for a startup that is starting its journey into Kubernetes

How Uber developed the open source, end-to-end distributed tracing Jaeger , now a CNCF project:

Distributed tracing is quickly becoming a must-have component in the tools that organizations use to monitor their complex, microservice-based architectures. At Uber, our open source distributed tracing system Jaeger saw large-scale internal adoption throughout 2016, integrated into hundreds of microservices and now recording thousands of traces every second.

Here is the story of how we got here, from investigating off-the-shelf solutions like Zipkin, to why we switched from pull to push architecture, and how distributed tracing will continue to evolve:

Our first experience with .NET core was when we developed our OSS feature management platform - Tweek (https://github.com/soluto/tweek). We wanted to create a solution that is able to run anywhere (super important for OSS), has excellent performance characteristics and can fit in a multi-container architecture. We decided to implement our rule engine processor in F# , our main service was implemented in C# and other components were built using JavaScript / TypeScript and Go.

Visual Studio Code worked really well for us as well, it worked well with all our polyglot services and the .Net core integration had great cross-platform developer experience (to be fair, F# was a bit trickier) - actually, each of our team members used a different OS (Ubuntu, macos, windows). Our production deployment ran for a time on Docker Swarm until we've decided to adopt Kubernetes with almost seamless migration process.

After our positive experience of running .Net core workloads in containers and developing Tweek's .Net services on non-windows machines, C# had gained back some of its popularity (originally lost to Node.js), and other teams have been using it for developing microservices, k8s sidecars (like https://github.com/Soluto/airbag), cli tools, serverless functions and other projects...

We are operating a smart water purification plant called AAA. AAA has a Docker-based AI platform, and we want to build several water purification plants like this. In addition, it plans to create a headquarters that manages these water purification plants in an integrated way and build a big data platform there. Although I don't know if Ansible AWX can replace Harbor or Kubernetes among the three solutions above, I would like to know which solution is suitable for us and why. May your business go well...
