I remember back in the day we were deploying a production video streaming server at a customer site, and a team from IBM deployed their analytics suite alongside us. We had over 8Gbps coming out of a single 1U server. The IBM installed a separate server for every Java process that their application needed, which was something like 8. It was ridiculous.

Doesn't kubernetes also have autoscaling capabilities? https://kubernetes.io/blog/2016/07/autoscaling-in-kubernetes...

That is autoscaling within the cluster.... not the cluster itself. Although, managed kubernetes clusters let you auto-scale the cluster itself, so i think the GP is wrong.

I misread the link... it is genuine cluster scaling

Beats me. It doesn't correspond to either virtual server nor hypervisors. It certainly doesn't correspond to real hardware. Cloud OS my butt... "Hey, let's take a zillion commodity cloud provider instances running on hypervisors, then install Ubuntu, then run Kubernetes on them, then run docker containers on them and fiddle about all day with yaml trying to make internal networking do insecure things to imitate real world infrastructure"

Just use Ansible if you miss YAML, and you can actually deploy to real hardware.

> What? Setting up a load balancer or nginx is considered complex now? It's not complex to set up a load balancer in a given specific environment. But it's another kind of ask to say "set up a load balancer, but also make it so that the load balancer also exists in future dev environments that can be auto-set-up and auto-teared-down. And also make it so that load balancer will work on dev laptops, AWS, Azure, google,…

In my mind standardisation is how we really solve problems in much of software development. Everything before that is just practice and/or hacks.

I'm fine with standardization, as long as I set the standard. For standard 0, I propose that the only spelling for "standardization" will be with a 'z' (which is itself pronounced "zee").

For me, and many others: infrastructure as code. Kubernetes is very complex and took a long time to learn properly. And there have been fires among the way. I plan to write extensively on my blog about it. But at the end of the day: having my entire application stack as YAML files, fully reproducible [1] is invaluable. Even cron jobs. Note: I don't use micro services, service meshes, or any fancy stuff. Just a plain…

According to the article you are wrong about "infrastructure as code". Kubernetes is infrastructure as data, specifically YAML files. Puppet and Chef are infrastructure as code. Edit: not sure why the down votes, I was just trying to point out what seems like a big distinction that the article is trying to make.

Weird that you're getting downvoted.

The difference between code and data is pretty big.

One implies an expectation that the user is going to write some kind of algorithm whereas the other is basically a config file.

Let's be real, if you are old enough to get that reference without Googling, you probably would not have lasted that long at a hip fintech company anyways :-P

So are you saying that, no matter what, if you want to reply your whole infrastructure as code (networks, dmz, hosts, services, apps, backups etc ) that you are going to have to reproduce that somehow (whatever the combo of AWS services are, OR just learn K8S Effectively, "every infrastructure as code project will reimplement Kubernetes in Bash"

Exactly. That's a great way to put it. A bunch of Bash glue reimplementing what Kubernetes already does. Poorly.

Bash glue has rarely failed me. Never used k8s, but the horror stories I hear ensure I won’t feel dirty for writing a little bash to solve problems anytime soon.

I work at a fintech that runs a rails monolith on k8s and you would probably puke at how cheap our hosting cost is given our AUM. Engineering is a funny thing.

Because Google made it. Same thing with Tensorflow. And, fun fact, both are massively overhyped and a real PITA to learn and use. But Google uses it, so hey.

IBM charged the customer for each server.
