MPLS is dead, Long live MPLS

The initial hype of SD-WAN claimed that MPLS was dead as SD-WAN was going to remove all need for SLA based circuits. Now that we’re several years in and have some experience under our collective belts, we take a look at whether or not the original hype was correct and what real world customers are doing when it comes to selecting circuits for their SD-WAN networks.

Designing far memory data structures: think outside the box

Designing far memory data structures: think outside the box Aguilera et al., HotOS’19

Last time out we looked at some of the trade-offs between RInKs and LInKs, and the advantages of local in-memory data structures. There’s another emerging option that we didn’t talk about there: the use of far-memory, memory attached to the network that can be remotely accessed without mediation by a local processor. For many data center applications this looks to me like it could be a compelling future choice.

Far memory brings many potential benefits over near memory: higher memory capacity through disaggregation, separate scaling between processing and far memory, better availability due to separate fault domains for far memory, and better shareability among processors.

It’s not all straightforward though. As we’ve seen a number of times before, there’s a trade-off between fast one-sided access that doesn’t involve the remote CPU, and a more traditional RPC style that does. In particular, if you end up needing to make multiple one-sided requests to get to the data you really need, it’s often faster to just go the RPC route.

Therefore, if we want to make full use of one-sided far memory, we need to think Continue reading

Announcing news.internetsociety.org – a way to follow what is published across all Internet Society sites

Today I’m pleased to announce a new site we have built that brings into one location links to all the content published across Internet Society websites:

news.internetsociety.org

This news site aggregates posts from our main website, from sites of our 130+ Chapters and Special Interest Groups (SIGs), and from certain other affiliated sites. On the site, you can:

• Search using keywords
• Filter the view based on the region
• Filter the view based on language
• Filter the view to see posts only from a specific source

For instance, you can see all the posts published by Chapters in Africa. Or you can see all the posts published in French, or Spanish, or Chinese… or Georgian.

Note that the filters can work together. By choosing “Africa” and “French” you will see only French posts from African Chapters. There’s a “Reset” link on the right side that will clear all the filters.

All the views also have unique URLs that you can share with people, or link to from other sites, email newsletters, etc. And of course the site has a master RSS feed that you can read in a RSS reader or other tool.

I find it quite Continue reading

Kubernetes Operators with Ansible Deep Dive: Part 1

Deploying applications on Red Hat OpenShift or Kubernetes has come a long way. These days, it's relatively easy to use OpenShift's GUI or something like Helm to deploy applications with minimal effort. Unfortunately, these tools don't typically address the needs of operations teams tasked with maintaining the health or scalability of the application - especially if the deployed application is something stateful like a database. This is where Operators come in.

An Operator is a method of packaging, deploying and managing a Kubernetes application.  Kubernetes Operators with Ansible exists to help you encode the operational knowledge of your application in Ansible.

What can we do with Ansible in a Kubernetes Operator? Because Ansible is now part of the Operator SDK, anything Operators could do should be able to be done with Ansible. It’s now possible to write an Operator as an Ansible Playbook or Role to manage components in Kubernetes clusters. In this blog, we're going to be diving into an example Operator.

For more information on Kubernetes Operators with Ansible please refer to the following resources:

• Ansible Operator: What is it? Why it Matters? What can you do with it?
• An introduction to Ansible Operators in Kubernetes

We Are on a Break ;)

It’s high time for another summer break (I get closer and closer to burnout every year - either I’m working too hard or I’m getting older ;).

Of course we’ll do our best to reply to support (and sales ;) requests, but it might take us a bit longer than usual. I will publish an occasional worth reading or watch out blog post, but don’t expect anything deeply technical for the new two months.

We’ll be back (hopefully refreshed and with tons of new content) in early September, starting with network automation course on September 3rd and VMware NSX workshop on September 10th.

In the meantime, try to get away from work (hint: automating stuff sometimes helps ;), turn off the Internet, and enjoy a few days in your favorite spot with your loved ones!

BrandPost: You Can’t Afford Not to Use a Business-Driven SD-WAN

Digital transformation and cloud initiatives are changing the way IT organizations are thinking about and architecting the wide area network. It is estimated that over 70 percent of applications have already moved to the cloud. Yet, the transformational promise of the cloud is falling short as conventional networks can’t keep pace with demands of the cloud. Why? Because today’s router-centric and basic SD-WAN architectures have either hit the wall or can’t keep up with traffic pattern shifts, distributed applications and the open security perimeters inherent to the cloud. This blog will explore the limitations of today’s WAN approaches, offering a better way forward with a business-first networking model.To read this article in full, please click here
