K3s comes by default with traefik as the ingress controller. I heard great things about it, but I prefer to use ingress-nginx. This is simply because I'm more familiar with it. You can choose pretty much any ingress controller you want for Kubernetes, so pick one according to your own preferences.

Scout APM
Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

I've started to use a web server called caddy. You should check it out; it's awesome. Configuration is so much simpler, and it has a lot of other advantages also! Built-in lets-encrypt handling -- you don't even have to do anything (other than setup DNS "A" and/or "AAAA" record!)

consul
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
That's a false statement as far as the technical aspects are concerned (Swarm is still usable and supported), but is a true statement when you look at the social aspects (Kubernetes won the container wars and now even Nomad is uncommon to run into).
Right now the company i'm in uses Swarm in a lot of places due to its simplicity (Compose file support) and low resource usage - Swarm hits the sweet spot when it comes to getting started with container orchestration and doing so without needing multiple people to wrangle the technical complexity of Kubernetes, or large VMs to deal with its resource usage, at least in on prem environments.
In combination with Portainer (https://www.portainer.io/) it's perhaps one of the best ways to get things done, when you expect everything to just work and aren't doing something too advanced (think along the lines of 10 servers, rather than 100, which is probably most of the deployments out there).
I actually wrote about some of its advantages in my blog post, "Docker Swarm over Kubernetes": https://blog.kronis.dev/articles/docker-swarm-over-kubernete...
That said, if there are any good options to replace Swarm, it has to either be Hashicorp Nomad (https://www.nomadproject.io/) which is a really nice platform, especially when coupled with Consul (https://www.consul.io/), as long as you can get past the weirdness of HCL. Alternatively, it has to be K3s (https://k3s.io/), which gives you Kubernetes without the insane bloat and hardware usage.
I actually benchmarked K3s against Docker Swarm in similar app deployments: 1 leader server, 2 follower servers, running a Ruby on Rails app and an ingress, while they're under load testing by K6 (https://k6.io/). I was attempting to see whether COVID contract tracking with GPS would be viable as far as the system load goes in languages with high abstraction level, here's more info about that: https://blog.kronis.dev/articles/covid-19-contact-tracing-wi...
Honestly, the results were pretty close - on the follower servers, the overhead of the orchestrator agents were a few percent (K3s being heavier, but a few dozen MB here or there not being too relevant), whereas the bigger differences were in the leader components, where K3s was heavier almost by a factor of two, which isn't too much when you consider how lightweight Swarm is (there was a difference of a few hundred MB) and the CPU usage was reasonably close in both of the cases as well. Sadly, the text of the paper is in Latvian, so it's probably of no use to anyone, but i advise you to do your own benchmarks! Being a student, i couldn't afford many servers then, so it's probably a good idea to benchmark those with more servers.
Of note, on those VPSes (4 GB of RAM, single core), the full Kubernetes wouldn't even start, whereas at work, trying to get the resources for also running Rancher on top of a "full" Kubernetes cluster (e.g. RKE) can also take needlessly long due to the backlash from ops. Also, personally i find the Compose syntax to be far easier to deal with, rather than the amalgamation that Kubernetes uses, Helm probably shouldn't even be a thing if the deployment descriptors weren't so bloated. Just look at this: https://docs.docker.com/compose/compose-file/compose-file-v3...
In short:
- Docker Swarm is pretty good when you're starting out with containers and is reasonably stable and easy to use -

For easier visibility and auditing, central store API keys in a solution like Vault and in a dedicated project.

If we are talking about "cloud-native", I would really recommend taking a look at nsq or nats. I am really big fanboy of NSQ [1], it is simple, easy to setup and conceptually easy to learn.

Thanks, I'll evaluate Flagsmith as well!
Not totally sure Flipper is in the same category - that's more a Ruby-specific library, no? I know they have a cloud offering, but that isn't open source.
One more I found: https://github.com/checkr/flagr

Shameless plug (it's my project!), but there's also Flagsmith - https://github.com/Flagsmith/flagsmith
For completeness, the other OS projects I know of are:

Are you thinking of something like nginx which would drop the cache periodically? Which would do this: https://github.com/trickstercache/trickster but for any http request?
