In remembrance of Internet Pioneer, founder and Chair of RIPE for 25 years, Postel Award recipient, and friend, Rob Blokzijl the RIPE NCC set up the “Rob Blokzijl Foundation”. The foundation recognises those who made substantial and sustained technical and operational contributions to the development of the Internet in the RIPE NCC service region, or supported or enabled others with the development of the Internet in the RIPE NCC service region.

The Rob Blokzijl Award will be awarded for the first time during RIPE 76 in May 2018. This is a Good Thing on so many levels.

HPE partners with Portworx for easier Kubernetes deployment

Hewlett Packard Enterprise (HPE) has partnered with Kubernetes container vendor Portworx to provide a reference configuration for enterprises to launch stateful container workloads on Kubernetes.Containers are a lightweight form of virtualization, where just what is needed is loaded rather than the full operating system like in a virtualized environment. Docker was the first with containers, but it has been steamrolled by Kubernetes, which was developed by Google. Google just had way more resources to bring to bear than Docker, a startup that has relied on venture funding.Also on Network World: Will containers kill the virtual machine? One of the big changes as containers have evolved is adopting the stateful condition. Initially they were stateless, meaning the data was erased from memory when the container was shut down at the completion of its workload. Stateful applications, on the other hand, are services that require retention of data, usually through a connection to a back-end database so they have persistent storage.To read this article in full, please click here

CI/CD For Networking Part 2

When using PKI certificates is critical that both DNS is working correctly and that hosts have their time synced via a reliable NTP server. In this part of the series I will build a utility server that will act as the DNS, NTP and root certificate authority. The utility server will use...

Gartner’s open model: How does Cumulus stack up?

As we’ve discussed in a previous blog post, it can be difficult to determine whether or not a vendor is truly as open as they claim to be. Sure, your network provider says they support open solutions, but the reality is they take advantage of open networking’s flexible definition to market not-so-flexible networks. How can you be certain that you’re investing in the open network your data center deserves?

Never fear, Gartner is here! Their report on gauging vendors’ openness provides you with five easy questions to help you take a machete to the forest of false advertisement. So, how does Cumulus Networks stack up to these requirements, and how have we maintained our dedication to open networking? Let’s take a look at Gartner’s criteria — we think you’ll find that this open model fits Cumulus like a glove.

1) How simple is the solution?

We’ve broken down the qualifications for a simple solution into three parts. First of all, managing your network should be easy from the moment it comes online. Cumulus Linux is an operating system that ensures a simple start. A few features that guarantee a confusion-free beginning include:

What is disaster recovery?

Disasters come in all shapes and sizes. It’s not just catastrophic events such as hurricanes, earthquakes and tornadoes, but also incidents such as cyber-attacks, equipment failures and even terrorism that can be classified as disasters.Companies and organizations prepare by creating disaster recovery plans that detail actions to take and processes to follow to resume mission-critical functions quickly and without major losses in revenues or business.

In the IT space, disaster recovery focuses on the IT systems that help support critical business functions. The term “business continuity” is often associated with disaster recovery, but the two terms aren’t completely interchangeable. Disaster recovery is a part of business continuity, which focuses more on keeping all aspects of a business running despite the disaster. Because IT systems these days are so critical to the success of the business, disaster recovery is a main pillar in the business continuity process.To read this article in full, please click here

Get ready to use Linux containers

One of the most exciting things to happen in the Linux world in the past few years is the emergence of containers — self-contained Linux environments that live inside another OS and provide a way to package and isolate applications.They're not quite virtual systems, since they rely on the host OS to operate, nor are they simply applications. Dan Walsh from Red Hat has said that on Linux, "everything is a container," reminding me of the days when people claimed that everything on Unix was a file. But the vision has less to do with the guts of the OS and more to do with explaining how containers work and how they are different than virtual systems in some very interesting and important ways.To read this article in full, please click here
