all-in-3 Openshift (OCP) cluster with OCS (storage) and CNV (Virtualization)

 

Another day, another "Edge" Architecture. This time let's see how the minimum all-in-one OCP/OCS/CNV would have to look like.

But first what are the key benefits:

  • Small footprint

  • High Availability

  • Virtualization with VM HA

  • HCI storage

  • Best containers platform there is

 

Okay, I got you this far, let me reward you now with a short 2 minutes demo on how this is going to work once you're done:

BMaaS Part 4 - Routed Networks / Bears at the edge

 

This is part 4 in the series of BareMetal-as-a-Service with Ironic. In this article I will focus on highly distributed architectures. Baremetal cloud as a service for the edge and large environments.

What would be a good use of this architecture? I can think of few examples:

- managing lifecycle of hundreds of individual x86 servers monitoring production of the goods in manufacturing industry 

- almost any x86 based IOT use case

- managing highly distributed infrastructure sitting in stores for the large retailers

- managing unreleased server equipment directly...Read more

Distributed Private Cloud Infrastructure - DCN / Edge

I have hesitated to post anything about Red Hat OpenStack Edge since it got introduced in OSP13 simply because I found it quite difficult to consume. Also the storage situation back then was .. not complete. Things improved overtime and now with OSP16.1 we can deploy our private cloud with the following features (which imho finally makes it production ready.):

- ceph storage at the edge / dcn

- one stack per site for better management and lifecycle

- improved routed networking configuration

- image caching at the edge

 

So why would anyone...Read more

Networking-Ansible for Baremetal Consumption - How to create your network automation driver.

 

It is not a big deal for me to admit that I am a huge nerd when it comes to managing baremetal infrastructure in the datacenter. I feel like a dying breed in the times where everyone just wants to swipe their credit card and go to the public clouds. Nevertheless, there are still workloads out there that are too expensive to run in public cloud or too sensitive to be exposed in the "public" space. Proper automation and the management of the resources in the datacenter goes a long way in...Read more

OpenShift on OpenStack - no-brainer on-prem solution

I have to admit, it has taken me a while to produce this next article. Today, however it's about to change and I am happy to introduce on this blog OpenShift on OpenStack - no-brain on-prem solution for building apps. What makes this combination so special? Here is the short list of the top integration features:

- Fully Automated IPI experience

- Ability to deploy on mix of VMs and BM nodes

- With true multitenancy for VMs, BMs, Storage, Networking

- Dynamic , multi-tier storage as a service

- Best performance (No double network...Read more

OpenStack mini-Summit in Triangle

We have a unique opportunity to bring the brightest OpenStack, Cloud and Open Infrastructure engineers, consultants and field experts to Triangle area between February 4th - 6th 2019. Please come join us at the Red Hat Tower these days and learn the latest advancements in Open Infrastructure. We are going to have exciting speakers, talks and demos. You will have opportunity to ask any OpenStack question and with the brain power we have available I have no doubt we will get it covered.

Here are the sessions that are currently scheduled:

Red Hat OpenStack Platform...Read more

BMaaS Part 3: Multi-tenancy

So far we have learned how to configure and provision baremetal nodes with OpenStack Ironic in Part 1 of the blog. We also configured our deployment to allow zero-touch discovery in Part 2. The next "LEGO" building block is to allow our tenants/project to isolate their baremetal resources. This unique OpenStack feature can take advantage of neutron to reach out to top of rack switches (TORs) via ml2 driver and dynamically assign a VLAN id to switch ports for corresponding nodes. 

With this functionality, your tenants can take ownership of the pool...Read more

Hypercool Infrastructure - HCI RHV/Gluster + OpenStack/CEPH

Last year (2017) at OpenStack summit in Boston a friend of mine (Randy Rubins) presented an interesting concept of deploying OpenStack Control plane (together with HCI compute/storage) on Hyper-Converged Red Hat Virtualization Platform (the upstream ovirt). The idea was to capture all the workloads (pets and cattle) in single integrated infrastructure.  I remember sitting there in that conference room and thinking about all the pros and cons of this solution. Both RHV (ovirt) and OpenStack comes with a sets of trade-offs. Combining both platforms together makes it a "Unicorn", hence the reason for Hyper-Cool name.  ...Read more

BMaaS Part 2: Adding Ironic Inspector and Autodiscovery to overcloud

In first part of the series we have learned how to properly deploy OpenStack Ironic with Red Hat OpenStack Platform 13 (OSP13). Today we will take our deployment to the next level and enable Inspection and Autodiscovery for baremetal nodes in overcloud.

Please note OpenStack Inspector is not officially supported in OSP13 mostly due to limitation of not being capable to run in HA fashion. The limitation has been addressed and is planned to be part of the product in future release. In a mean time Red Hat requires to create support exception...Read more

BMaaS Part 1: Deploying OpenStack Ironic with Red Hat OSP13 / TripleO Queens

OpenStack Ironic is one of the most exciting project I had pleasure to work with and help my clients with in the last year. Project Ironic is all about provisioning clusters of Baremetal nodes based on images stored in Glance with assigned networks managed by Neutron.

In the past Ironic has been neglected by System Architects and System Integrators mostly due to lack of feature parity comparable to more traditional baremetal bootstrap mechanisms. Now the feature gap has been mostly closed and at the same time Ironic can take advantages of other components and methodologies...Read more
