IMO Red Hat has been on top of recent developments.
OpenShift is (arguably) the best PaaS Kubernetes distribution, and certainly the most enterprise-ready one. I use it in production and it's a great piece of engineering. They heavily contribute back to Kubernetes upstream instead of forking it. Red Hat is responsible for many important Kubernetes features like RBAC.
They acquired Ansible and, recently, CoreOS.
Software Collections make it really easy to run an up-to-date software stack on RHEL by decoupling it from the base OS (which is the way to go, IMO).
And of all the IdPs I recently evaluated, Keycloak sucks the least.
Legitimately curious: the main issue with running containers on Linux is the bad state of the Linux kernel as far as security is concerned. Even with SELinux, it's risky to run multi-tenant containers on Linux due to the massive attack surface, necessitating things like [1] or lightweight VMs.
How does SmartOS solve this?
Also, does the Joyent stack have an OpenShift equivalent? Triton wants my credit card details to sign up with their public cloud, but I might grab a spare box and give it a try.
...if after reading that you still have specific questions, ask.
You don't need a credit card, if you don't want to run it on Joyent's servers, you can run Triton for free on your own at home, at work, (or someone else's) infrastructure. All of that technology is freely available at Github at no cost other than reading a little bit of documentation and investing some time to set it up following the instructions.
Out of curiosity, do Digital Ocean, Hetzner, Azure or AWS not ask for a credit card?
Well, one is forced to work with that inferior tooling and is not allowed to change it. This is excruciatingly painful and generates a lot of resent when one knows that there is far superior tooling available, gratis, with much higher quality support and way more competent engineers working on that tooling.
I've tried to use PatteryFly a few times, it's actually a pretty terrible system. the biggest drawback is the lack of documentation...as you click through what they call documentation it's full of missing content and 404's. Personally, it's just better to use adminLTE or Twitter Bootstrap.
With the exception of RHEL, it's just like most of Red Hat's products...purchased from someone else, half-baked, and a rather pathetic attempt to stay relevant. It seems that the only support is from internal RH devs and if you look at a lot of Red Hat's other products, even they can't really figure out how to use it (see ManageIQ).
> It seems that the only support is from internal RH devs
That's because it's an internal RH framework. Red Hat happens to open source most of their stuff, so they put some effort into marketing PatternFly, but it's still mostly used by themselves.
That being said, the people on their Slack channel are extremely helpful!
