What I like about Kubernetes is that it’s a platform you get things like exponential backoff, replication, liveness and health checking and so forth as part of the platform, and plugins for metric collection and monitoring are fairly standard. These are things I don’t even feel most PaaS have done a great job on across the board, so I can certainly see the appeal of having Kubernetes under the hood.
- stevepike 6y agoYeah, there's a whole category of apps that run on heroku with maybe 10 dynos tops that could definitely be deployed on kubernetes with manual / web ui-based configuration.
- k__ 6y agoPaaS came before K8s, it's the minimum that K8s is better than PaaS.
- jchw 6y agoI actually don’t see why a PaaS couldn’t do all of this better. Especially at larger companies, where containers and monitoring have been the norm internally forever, it is unclear why PaaS offerings still feel primitive... maybe there is some technology limitation here. Edit: disclaimer, I have not used a PaaS service in a couple years.
- foxtr0t 6y agoYeah that is understandable, k8s is a platform with a plethora of capabilities. On the other hand, the vast majority of organizations using k8s have multiple users that have multiple work streams and multiple applications (not true by definition, but close). This lends itself to a code as configuration approach, and makes managing orchestration through a UI risky and error prone. We review code, not clicks. Further, K8s exposes an YAML interface because it is relatively human readable and of course is machine readable. I'm sure the k8s community encourages users to build on top of this. Want to really do code as config? Write a nice DSL in your favorite scripting language to produce these YAMLs. Submit that as source. You've now automated away the vast majority of toil related to k8s YAML config, because your code can be: 1. modular by design 2. tested 3. tracked as code etc etc
