Why the Kubernetes Kids can't hurt Bezos' Amazon beast


Did anybody actaully try to deploy and run Kubernetes on google cloud? With google's native offering. They supposed to have an amazing offering and tight integration with all their services, right?

Well, not so much.

Upgrading of the cluster works great, an engineer can do full cycle upgrade to a next k8s version in half an hour. However, the master node will go down for 1-2 minutes (!) when a manually issued cli command applied. Yup, that's right - there is no way to version-control this process. Nothing like CloudFormation.

Now, running services is a breeze. Except passing traffic in (so-called "ingress"). Sure, you can create a load-balancer for each service, that's pretty easy. But there is no DNS integration, no logs, no metrics out of that loadbalancer. And for each little micro-service running you'll need a new loadbalancer provisioned.

But that's not all that bad. There is Cloud Endpoints ("API Gateway") - where services from kubernetes can be integrated with managed API. But look up the docs of that integration for kubernetes and compare it with AWS API gateway integration for pretty much anything.

And these are just a few issues you'll run into immediately. Sure, if you're a startup - not a big deal. Each team can manage own kubernetes cluster. But if you're an enterprise that requires proper configuration management, version control of changes, availability, documentation, integration with all other systems, support - then kubernetes will be a very hard to sell.

It like openstack - but for containers.

Dell EMC man: Hyperconverged is love, hyperconverged is life, but won't kill SAN yet


Interesting argument about latencies and throughput for on-prem storage systems but it's probably too self-comforting.

Your customers already moving to the cloud with full speed and monsters like SAP are forced to accommodate.

They already have instances with 4-16TB of memory on the roadmap...


The conversation evolves around if on-prem type of customers will continue to use legacy monster app that requires all these SAN arrays and infra. They might ignore the trend, yes. But they going to miss the boat... It's not about on-prem or cloud, it's how fast you ship and how easy to change your product. If they won't be able to figure out how to embed reliability and agility into their own software - they'll probably be out of business.
