On-Demand execution with Red Hat OpenShift

Being able to dynamically scale infrastructure is no longer a nice-to-have - it is a requirement. The advent of cloud and container platforms have shifted the expectations in terms of consuming IT infrastructure and services. As a result, any tool that is used to manage infrastructure needs to be able to handle this ever-changing landscape. 

Red Hat Ansible Automation Platform provides customers with the tools that they need to build an automation solution. The component automation controller helps enterprises automate and scale with confidence. 

One of the ways we can scale our automation is to leverage container groups. Container groups are part of automation controller, and allow customers to leverage an existing OpenShift cluster to create on-demand execution capacity for Ansible Playbooks. When a job is executed from automation controller, it creates pods on the target OpenShift cluster, which runs the automation job. Once the job is complete, the pods are terminated. This provides a number of benefits:

  • Fewer wasted resources - infrastructure isn’t sitting idle while waiting for automation jobs. Once a job completes, the resources are instantly freed up.
  • Deliver execution capacity quicker - we don’t need to provision infrastructure up front.
  • Less focus on capacity Continue reading

How to Celebrate Valentine’s Day with Your Single Friends 

Valentine’s Day is just a few months away, so it’s time to think about what you’re going to do this year. It is believed that Valentine’s Day is just for people who are romantically and passionately in love. However that is not the case, you can still enjoy Valentine’s Day with your loved ones even if you are single. This article will teach you how to celebrate Valentine’s Day with your single friends, no matter where they are in their dating journey!

Have a Movie Marathon

You and your single friends can get together to watch movies. The best thing about this is you don’t even have to change out of your pajamas! Buy a big tub of popcorn, order some pizzas and cuddle up on the couch surrounded by blankets. You’ll all love this because it’s just like being in high school again!

Go To a Comedy Show

If you’re looking for something more interactive than watching movies, then check out a comedy show! It will be exciting and hilarious at once so everyone should enjoy themselves.

Valentine’s Day Charity Event

Another option is to do a charity event. You and your single friends can volunteer at an Continue reading

Startup claims its passive data-center cooling system generates power

A Canadian startup called Infinidium Power claims it has a new data-center cooling system that will generate power from the heat generated by the servers deployed within it.Infinidium claims its Next Generation Datacenter Cooling and Power Supply Infrastructure can reduce both operating and capital costs by as much as 50% through air cooling. It has its own compute containers called the Vortex Vacuum Chamber and a low-voltage direct-current smart Nanogrid, which saves power by not doing AC-to-DC conversion.A video animation on the company's site explains how the Vortex Vacuum Chamber sucks in cold air to a bell-shaped chamber where server boards are arranged in levels of circular racks. It uses a combination of the shape of the chamber and physics (warm air rises, cold air sinks) to generate power. Cool air is pulled into the chamber, and as heat generated by the servers warms the air it rises to a vent in the ceiling where it drives a turbine on its way out, generating power.To read this article in full, please click here

Feedback: ipSpace.net Materials

Andy Lemin sent me such a wonderful review of ipSpace.net materials that I simply couldn’t resist publishing it ;)

ipSpace.net is probably my favorite networking resource out there. After spending years with other training content sites which are geared around certifications, ipspace.net provides a totally unique source of vendor neutral opinions, information, and anecdotes – the kind of information that is just not available anywhere else. And to top it off, is presented by a wonderful speaker who is passionate, smart and really knows his stuff!

The difference between an engineer who just has certs versus an engineer who has a rounded and wide view of the whole industry is massive. An engineer with certs can configure your network, but an engineer with all the knowledge this site provides, is someone who can question why and challenge how we can configure your network in a better way.

Interop LDP and Segment Routing with IP infusion and MikroTik

Introduction

During networking field day service provider 1 there was a ton of talk about segment routing (SR) and ethernet virtual private networks (EVPN). One of the biggest questions was “how do we get there?” and while we won’t examine EVPN in this post (it’s coming in a future post don’t worry) we will look at how you can take advantage of SR while still having large portions of LDP in your network.

The team here at IP architechs works on a lot of MikroTik and whitebox gear so we’ll focus on a deployment using MikroTik and IP infusion.

MPLS and IGP setup

The first thing to accomplish is end to end reachability between the provider edge (PE) routers. MikroTik doesn’t support IS-IS so we will have to perform redistribution between the IS-IS segment and the OSPF segment as seen above.

MPLS only requires the /32s of the loopbacks for functionality so redistribution is limited to the /32 loopbacks of the PE routers.

 seq 10 permit 100.127.2.0/24 eq 32

Pluribus NOS upgrades target Kubernetes, cloud fabric management

Pluribus Networks has significantly upgraded its switch-fabric software to provide a better handle on distributed, containerized enterprise-cloud resources.The upgrades add three new fabric-monitoring capabilities—FlowTracker, KubeTracker, and Virtualized Packet Broker Service—to Netvisor One, the company’s virtualized Linux-based NOS that provides Layer 2 and Layer 3 networking and distributed fabric intelligence.The NOS virtualizes switch hardware and implements the company’s Adaptive Cloud Fabric software-defined networking package. Adaptive Cloud Fabric operates without a controller and can be deployed across a data center or targeted to specific racks, pods, server farms, or hyperconverged infrastructures, the company said.To read this article in full, please click here
