runc vs gvisor (runsc) vs rkt vs KataContainers vs NablaContainers
knowledge dump on container runtimes
KataContainers
- image coupled with kernel
- light vm layer
- can run in nested virturalization environments if hardware supports and you can enable it in bios (ex. only bare metal EC2 instances, limits many cloud providers)
- slower startup time
- OCI compliant
- previously known as ClearContainers by Intel

DDD in golang

This is my response to an email asking about Domain-Driven Design in golang project.

Thank you for getting in touch. Below you will find my thoughts on how golang works with DDD, changing it. This is merely a perception of how things worked out for us in a single project.

That project has a relatively well-known domain. My colleagues on this project are very knowledgeable, thoughtful and invested in quality design. The story spelled out below is a result of countless hours spent discussing and refining the approach.

Conclusions could be very different, if there was a different project, team or a story-teller.
