* Secret storage
* Pet sets(coming along in k8s)
* Leader election
* Persistent volumes
It looks like Blox can address some of this stuff, but kubernetes is providing this stuff OOTB.. It's also locked to vendor-specific service offerings. This isn't to say Kubernetes doesn't have room for improvement; its AWS integrations could use some work(Application Load Balancer support, etc).
But: We don't support ALB yet because we haven't actually found a compelling use-case for it. Ingress on Kubernetes seems to do everything ALB can, but without the limitations. At least that's what we've thought so far, so if you have a use case do open an issue explaining it, and we can look at adding it :-)
* Websockets support
* Http/2 support
* Layer 7 routing + Route to specific ports(stop sending all traffic to all nodes and preserve source ip)
* Request tracing(recently added to ALB)
I hope this doesn't sound too negative, and I KNOW you do a TON of work on this stuff, but there often seems a disconnect between the people working on the kubernetes integrations and the feedback coming through from people trying to run businesses on AWS. Which happens; it's tough to be in both roles if your business isn't infrastructure.
