Swarm Orchestration in Docker Enterprise Edition
At DockerCon Europe, we announced that the next release of Docker Enterprise Edition (Docker EE) would include Kubernetes integration. We’re really excited about bringing Kubernetes to our customer base and continuing to increase our involvement within the community. But it’s equally important for us to note that Swarm orchestration is not going away. Swarm forms an integral cluster management component of the Docker EE platform; in addition, Swarm will operate side-by-side with Kubernetes in a Docker EE cluster, allowing customers to select, based on their needs, the most suitable orchestration tool at application deployment time.
Here are just a few reasons that Swarm is integral to the Docker EE solution:
- Support our existing customers and ecosystem integrations
- Provide customers the flexibility in choice of orchestrators
- Provide secure and highly available clustering architecture
Existing Customers and Ecosystem Integrations
Docker now has hundreds of Docker EE customers who have standardized on Swarm orchestration. In fact, at our Customer Summit during DockerCon, all of the customers stated that they intend to continue using Swarm even with the Kubernetes announcement. Having both orchestration options available is definitely a plus for some of these customers that have organizations within the company using both Swarm and Continue reading
Gordon Bell Looks Out Into A Parallel World
It was 31 years ago when Alan Karp, then an IBM employee, decided to put up $100 of his own money in hopes of solving a vexing issue for him and others in the computing field. When looking at the HPC space, there were supercomputers armed with eight powerful processors and designed to run the biggest applications of the day. However, there also were people putting 1,000 wimpy chips into machines that leveraged parallelism to run workloads, a rarity at the time.
According to Amdahl’s Law in 1986, even if 95 percent of a workload runs in parallel, the speedup …

SD-WAN 101: Introduction to Software-Defined Wide Area Networks
No doubt, there’s a plethora of information on the web about SD-WAN, short for Software-Defined Wide Area Network. It’s the next big thing in networking and everyone’s writing, making a video, or talking about it. But, if you’re like me, any time a new technology emerges, I prefer to learn the fundamentals before jumping into... Read more →
Deploy360 at IETF 100, Day 5: Zaìjiàn from the Lion City
There’s a couple of sessions of interest on the last day of IETF 100 before we wrap up for the week. Friday is only a half-day, but still manages to fit in sessions on human rights considerations and encryption. Human rights is not a topic that Deploy360 typically covers, but we have been increasingly asked to discuss the IRTF initiative on Human Rights Protocols Considerations. (There’s also a recent IETF Journal article on Human Rights Protocol Considerations.)
HRPC is researching the human rights threats on the Internet, whether standards and protocols can enable or threaten these, and is developing recommendations on developing Internet protocols around this. It recently published RFC 8080 outlining human rights threats on the Internet, and will be meeting at 09.30 SGT/UTC+8 to discuss three other drafts relating to Freedom of Association on the Internet, the Politics of Standards, and Unrequested Communications. There will also be a presentation on Chainiac: end-to-end software supply chain security and transparency, plus the next steps forward will be discussed.
NOTE: If you are unable to attend IETF 100 in person, there are multiple ways to participate remotely.
PERC is also meeting at the same time, and has three drafts up for discussion. Continue reading
IPv6 Migration: 5 Best Practices
Follow these expert tips to smooth the process of adopting the new Internet Protocol standard.
Pluribus Networks… 2 Years Later
I first met Pluribus Networks 2.5 years ago during their Networking Field Day 9 presentation, which turned controversial enough that I was advised not to wear the same sweater during NFD16 to avoid jinxing another presentation (I also admit to be a bit biased in those days based on marketing deja-moo from a Pluribus sales guy I’d been exposed to during a customer engagement).
Pluribus NFD16 presentations were better; here’s what I got from them:

Basics of VRF(Virtual Routing forwarding)
Today I am going to talk about one of the most important concept on which MPLS works. I understand many of you already knew about the MPLS but some of you guys are still want me to explain the concept of MPLS and the MPLS starts from the concept of VRF.
Before we will start with the concept of the VRF, Please subscribe our Youtube Channel, as we are going to upload many networking videos there soon.

What is VRF- Virtual Routing forwarding ?
As you already knew that VRF stands for Virtual Routing Forwarding and is a separate routing table within a router. VRFs are to a router what VLANs are to a switch. Using VRFs, it is possible to virtualize a single router into several instances, each of them being (relatively) independent of each other, allowing for overlapping subnets, separate instances of routing protocols, separate set of interfaces assigned to each VRF.
In other words you can say that VRF stands for virtual routing and forwarding. When you create a vrf, you tell it what routes to import/export. Then you assign that vrf to an interface. Once the vrf is attached to Continue reading
IO-500 Goes Where No HPC Storage Metric Has Gone Before
The landscape of HPC storage performance measurement is littered with unrealistic expectations. While there are seemingly endless strings of benchmarks aimed at providing balanced metrics, these far too often come from the vendors themselves.
What is needed is an independent set of measurements for supercomputing storage environments that takes into account all of the many nuances of HPC (versus enterprise) setups. Of course, building such a benchmark suite is no simple task—and ranking the results is not an easy exercise either because there are a great many dependencies; differences between individual machines, networks, memory and I/O tricks in software, and …

Oak Ridge Lab’s Quantum Simulator Pulls HPC Future Closer
Oak Ridge National Laboratory has been investing heavily in quantum computing across the board. From testing new devices, programming models, and figuring out workflows that combine classical bits with qubits, this is where the DoE quantum investment seems to be centered.
Teams at Oak Ridge have access to the range of available quantum hardware devices—something that is now possible without having to own the difficult-to-manage quantum computer on sight. IBM’s Q processor is available through a web interface, as is D-Wave’s technology, which means researchers at ORNL can test their quantum applications on actual hardware. As we just …

How to gauge your network’s openness
So, you’ve done your research, learned about the many benefits of open networking, and decided you’re interested in building an open network. Congratulations, and welcome to the future of networking! You’ve made a great first step, but maybe you’re concerned about where to begin when it comes to vendors. A lot of network providers will claim that they have open solutions…but how can you be sure you’re choosing the best one? Or how can you determine if your vendor is truly an open solution? Fortunately, there are ways to gauge if your solution is as open as you need it to be. If you don’t want to get duped by phony open vendors, make sure to keep these three things in mind:
The definition of “open networking” is not set in stone
While there are common criteria and ideologies that tend to be associated with open networks, the definition of open networking is still very fluid and can mean different things to different vendors. So, when you’re trying to decide which vendor to go with, don’t let them off easy with simple answers. Ask specific questions about what exactly “open” means to them. Simplicity, flexibility, and modularity are Continue reading
