Resources for cloud independent architecture design?

by carnitas on 4/21/20, 8:20 PM with 12 comments

Hi there! I've been tasked with lifting some existing architecture and build systems to the cloud. I want to go with Kubernetes or some solution that allows for little to no cloud vendor lock in, allowing system to be run on prem as well.

Can anybody recommend a book or other resources that deals with these requirements? I've read "Designing Data Intensive Applications" and find it wonderful. I wonder if there's something similar for architecture / kubernetes.

Thanks for your suggestion!

    These requirements basically entail that you're able to achieve feature parity with an on-premises datacenter; thus, you're treating various cloud providers as vendors for VMs, storage, and network. "Treating the cloud like it's a datacenter" isn't exactly a best practice from a pure architectural perspective.

    That said, there may well be business constraints forcing the decision, and that's fine--I'm not trying to pass judgement any! My point is simply that by building something that can be deployed to any and all environments you're reducing the list of what can be used down to a very small set of primitives.

    You may be interested in "Zero to JupyterHub with Kubernetes"[0]. Here's an excerpt of the description:

    """ This project will help you set up your own JupyterHub on a cloud and leverage the clouds scalable nature to support large groups of users. Thanks to Kubernetes, we are not tied to a specific cloud provider. """

    What is your product? You can achieve cloud independency with an RPM and an ssh connection... then you can eventually move to installing the RPM in a docker image you build if you want to deploy in a more immutable way.

    If you are going to use Kubernetes I hope it gives you a lot more than the former.

    hint: it usually doesn't if you don't have multiple teams.

    What’s the objective?

    There are good reasons to do this, but it’s unlikely to save money. End of the day, you’re going to be committed (“locked in”) to something, whether that be a cloud provider, software company or budget for staff.

    Do you need k8s?

    Have you thought of PAaS and managed databases? Just thinking. Of course if you’re all good to go on kubernetes go on then!
