Lenovo, Scale partner for hyperconverged edge servers

OEM Lenovo and hyperconverged infrastructure (HCI) platform developer Scale Computing have partnered to offer an out-of-the-box HCI platform specifically for edge computing deployments.Dubbed the Scale Computing HC3 Edge Platform on Lenovo Servers, the solution is an integration of Scale's HC3 software platform — what it calls “a data center in a box” — on Lenovo server hardware. HC3 brings together compute, storage, and virtualization into a comprehensive system with automated management.The Lenovo/Scale solution provides "edge infrastructure that has the capacity to run various IT and OT workloads, is space-conscious, and can be managed at each individual location by generalists," said Wilfredo Sotolongo, vice president and general manager of IoT for Lenovo's data center group, in a statement.To read this article in full, please click here

BrandPost: How 802.11ax Improves the Experience for Everyone

The next advance in Wi-Fi, 802.11ax, is fast approaching. As we seek to raise the performance bar yet again for the sixth generation of Wi-Fi, the traditional techniques used in 802.11n and 802.11ac – wider RF channels, more MIMO antennas, higher QAM modulation – have been pushed almost to the limit, and it’s time to look for new ideas.802.11ax introduces techniques for ‘massive parallelism,’ especially OFDMA, multi-user MIMO, and ‘BSS coloring.’ All of these require the access point to make control decisions that have a significant effect on network performance, a new emphasis for Wi-Fi that will move access point networks closer to cellular base station infrastructure in terms of functionality.To read this article in full, please click here

The Easiest Way to go Faster is to go Faster

400G-blog-image

Why 400G Ethernet? In one sentence, because the easiest way to go faster is to go faster.
Over time, Ethernet speed transitions have been the primary driver for improving both the throughput and price-performance of datacenter networks. 400G Ethernet is the next major transition on this journey. While 100G Ethernet is still ramping up rapidly this year and next, it is projected that by the end of 2021 400G Ethernet will represent the majority of Ethernet bandwidth shipped.

The best enterprise level firewalls: Rating 10 top products

You know you need to protect your company from unauthorized or unwanted access. You need a network-security tool that examines the flow of packets in and out of the enterprise, governed by rules that decide whether that flow is safe, malicious or questionable and in need of inspection. You need a firewall.Recognizing that you need a firewall is the first – and most obvious -- step. The next crucial step in the decision-making process is determining which firewall features and policies best-suit your company’s needs.Today’s enterprise firewalls must be able to secure an increasingly complex network that includes traditional on-premises data center deployments, remote offices and a range of cloud environments. Then you have to implement and test the firewall once it's installed. Perhaps the only element more complex than configuring, testing and managing a next-generation firewall is the decision-making process regarding which product to trust with your enterprise security.To read this article in full, please click here(Insider Story)

3 Customer Stories You Don’t Want to Miss at DockerCon Barcelona 2018

One of the great things about DockerCon is the opportunity to learn from your peers and find out what they’re doing. We’re pleased to announce several of the sessions in our Customer Stories track. In the track, you’ll hear from your peers who are using Docker Enterprise to modernize legacy applications, build new services and products, and transform the customer experience.

These are just a few of the sessions in the catalog today. You can browse the full list of sessions here. We also have a few more we’ll announce over the coming weeks (some customers just like to keep things under wraps for a little longer).

Figuring Out AWS Networking

One of my friends reviewing the material of my AWS Networking webinar sent me this remark:

I'm always interested in hearing more about how AWS network works under the hood – it’s difficult to gain that knowledge.

As always, it’s almost impossible to find out the behind-the-scenes details, and whatever Amazon is telling you at their re:Invent conference should be taken with a truckload of salt… but it’s relatively easy to figure out a lot of things just by observing them and performing controlled experiments.

YANG, OpenAPI, Swagger and Code Generation

Sometimes during exploration or projects, I want to take a YANG model and convert it along with related dependencies to a Swagger format (think OpenAPI if you’re not familiar with this) so I can create a REST or RESTConf API interface. OpenDayLight does something very similar for it’s Swagger based North Bound Interface (NBI), more information here and just being able to look at the model this way is sometimes helpful. If you’re wondering how helpful this could be, think about developing a client. Using this approach, it’s possible to create stub client and server code for a software implementation, leaving just the logic of what to do when a POST is made or a GET is requested etc.

You may be familiar enough with YANG to know that YANG is a modeling language with its own extensible type system. These YANG models are mostly used for modeling how a programmatic interface to control a feature should be on routers and switches. More recently thanks to the wave of automation sweeping across the globe, YANG models are now used for modeling services, which in turn are rendered over one or more nodes by something else. We’re not going to cover Continue reading
