Beta Docker for Mac and Windows with Kubernetes

Today, as part of our effort to bring Kubernetes support to the Docker platform, we’re excited to announce that we will also add optional Kubernetes to Docker Community Edition for Mac and Windows. We’re demoing previews at DockerCon (stop by the Docker booth!) and will have a beta program ready at the end of 2017. Sign up to be notified when the beta is ready.

With Kubernetes support in Docker CE for Mac and Windows, Docker Inc. can provide customers an end-to-end suite of container-management software and services that span from developer workstations, through test and CI/CD through to production on-prem or in the cloud.

Docker for Mac and Windows are the most popular way to configure a Docker dev environment and are used everyday by hundreds of thousands of developers to build, test and debug containerized apps. Docker for Mac and Windows are popular because they’re simple to install, stay up-to-date automatically and are tightly integrated with macOS and Windows respectively.

The Kubernetes community has built solid solutions for installing limited Kubernetes development setups on developer workstations, including Minikube (itself based partly on the docker-machine project that predated Docker for Mac and Windows). Common to these solutions however, Continue reading

IETF 100 Hackathon: Bringing Innovation and Running Code to the IETF

Interested in contributing running code to the Internet Engineering Task Force (IETF)? Do you see a problem with DNS, DNSSEC, IPv6, TLS, or something else that you want to help fix?

The IETF is holding its next meeting in Singapore in November. Just before IETF 100, on 11-12 November, is a Hackathon to encourage developers to discuss, collaborate and develop utilities, ideas, sample code and solutions that show practical implementations of IETF standards.

Check out the Hackathon Wiki to learn more about how to register, get involved in a project, add your own topic of interest, or even participate remotely if you can’t make it to Singapore next month. You can also read more about a past Hackathon in this IETF Journal article.

As an added bonus, there are some prizes on the line! A panel of judges announces winners in several categories at the end of the event, with winners choosing from sponsor-donated prizes.

Remember, the IETF needs operational expertise to make sure its protocols and standards actually work in real life networks.

NSX Real World Use Cases for Pivotal Cloud Foundry

Pivotal cloud foundry is the leading PaaS solution for enterprise customers today, providing a fast way to convert their ideas from conception to production. This is achieved by providing a platform to run their code in any cloud and any language taking care of all the infrastructure stuff for them.

From building the container image, compiling it with the required runtime, deploying it in a highly available mode and connecting it to the required services, PCF allows dev shops to concentrate on developing their code.

While the platform is providing developers with the most simplified experience conceivable, under the hood there are many moving parts that make that happen and plumbing all these parts can be complex. That’s where customers are really enjoying the power of VMware’s SDDC, and the glue between the PaaS and SDDC layers is NSX, it is the enabler that makes it all work.

In this blog post, I detail some of the main uses cases customers has already deployed NSX for PCF on top of vSphere and how PCF and NSX are much better together in the real world.

The use cases customers are deploying with NSX for PCF are varied and ill divide them Continue reading

KRACK proves we need more encryption on the Internet

A serious weakness in Wi-Fi security was made public earlier today. The Key Reinstallation Attack (KRACK) can break Wi-Fi encryption, opening your data up to eavesdropping. This, combined with issues in Linux and Android, make it possible for attackers to change websites you view. This is a serious problem for Wi-Fi Protected Access 2 (WPA2), a protocol used in millions of networks worldwide.

Luckily, the use of Transport Layer Security (TLS) is on the rise. Mozilla’s data shows that over 60% of pages loaded in Firefox use TLS. More and more companies are using encryption for all traffic and removing the ability to connect to unencrypted versions of their sites. When connecting to these sites, KRACK isn’t as big of a deal, because the data is encrypted before it’s sent across Wi-Fi. Even if WPA2 is broken, the data is still secure.

Unfortunately there are still millions of sites that don’t provide this security. Their users are vulnerable to eavesdropping, fake content, malware injection, and more. We need more companies and operators to use TLS and HTTP Strict Transport Security (HSTS) to mitigate the potential impact of KRACK.
Internet traffic exists in layers, which makes it possible to use more Continue reading

IS-IS Multi Instance: RFC8202

Multi-Instance IS-IS
One of the nice things about IS-IS is the ability to run IPv6 and IPv4 in the same protocol, over a single instance. So long as the two topologies are congruent, deploying v6 as dual stack is very simply. But what if your topologies are not congruent? The figure below illustrates the difference.

In this network, there are two topologies, and each topology has two different set of level 1/level 2 flooding domain boundaries. If topology 1 is running IPv4, and topology 2 is running IPv4, it is difficult to describe such a pair of topologies with “standard” IS-IS. The actual flooding process assumes the flooding domain boundaries are on the same intermediate systems, or that the two topologies are congruent.

One way to solve this problem today is to use IS-IS multi-topology, which allows the IPv6 and IPv4 routing information to be carried in separate TLVs so two different Link State Databases (LSDBs), so each IS can compute a different Shortest Path Tree (SPT), one for IPv4, and another for IPv6. Some engineers might find the concept of multi-topology confusing, and it seems like it might be overkill for other use cases. For instance, perhaps you do Continue reading

Why leave a vendor job….twice?

Over the past few months I’ve been working hard on my new start-up company PeakFactory, it’s going really well, but for this post I want to focus on the reason why I chose to leave the companies I used to work for. I thought this was relevant, as many people have asked me why, but also in general there is a lot of discussion how to advance your career in different directions.

Why leave a comfortable and good job at all?

Back in 2013 I was working in a very good position, where I had a lot of freedom in choosing the customers I’d like to work on and was involved in all technical aspects of a project (pre-sales, proof of concepts, implementation and support). Still I had this feeling that I wanted to explore more an different areas for a wider audience. Which is why I decided to start working for a networking vendor. My main reason for choosing a vendor is that I could leverage my experience in the technology and apply it for a wider audience (maybe even worldwide)

Why work for Cisco and Juniper?

In early 2014 I got in touch with Cisco and I left Continue reading

NetDevOps: what does it even mean?

Move over “selfie” — “NetDevOps” is the hottest buzzword that everybody is talking about! It’s so popular that the term even has its own hashtag on Twitter. But when you take the word out of social media, does anyone really know what it means? Or how this perfect portmanteau can revolutionize your data center? Let’s take a moment to discuss what NetDevOps really is all about. In this post, we’ll go over the definition, the best practices, and the tech that best incorporates NetDevOps. Now, when you see #NetDevOps appear on your feed, you can tweet it out with confidence.

What does it all mean?

If you understand the basic principles of DevOps, then congratulations! You’re two-thirds of the way to grasping the concept of NetDevOps. For the uninitiated, DevOps embraces the ideology of interoperability and communication between the development and operations teams in order to break down silos and create better products. The movement also encourages automation and monitoring in order to increase efficiency and reduce error.

DevOps is certainly a great movement, but like the VCR and the DVD player, something new came along and improved upon it. This is where NetDevOps comes in. So, what exactly is Continue reading

IBM Preps Power9 For AI And HPC Launch, Forges Big NUMA Iron

After a long, long wait and years of anticipation, it looks like IBM is finally getting ready to ship commercial versions of its Power9 chips, and as expected, its first salvo of processors aimed at the datacenter will be aimed at HPC, data analytics, and machine learning workloads.

We are also catching wind about IBM’s Power9-based scale-up NUMA machines, which will debut sometime next year and take on big iron systems based on Intel Xeon SP, Oracle Sparc M8, and Fujitsu Sparc64-XII processors as well as give some competition to IBM’s own System z14 mainframes.
