IDG Contributor Network: AI and 5G: Entering a new world of data

Today the telecom industry has identified the need for faster end-user-data rates. Previously users were happy to call and text each other. However, now mobile communication has converted our lives in such a dramatic way it is hard to imagine this type of communication anymore.Nowadays, we are leaning more towards imaging and VR/AR video-based communication. Therefore, considering such needs, these applications are looking for a new type of network. Immersive experiences with 360° video applications require a lot of data and a zero-lag network.To give you a quick idea, VR with a resolution equivalent to 4K TV resolution would require a bandwidth of 1Gbps for a smooth play or 2.5 Gbps for interactive; both requiring a minimal latency of 10ms and minimal delay. And that's for round-trip time. Soon these applications will target the smartphone, putting additional strains on networks. As AR/VR services grow in popularity, the proposed 5G networks will yield the speed and the needed performance.To read this article in full, please click here

Cisco forges tighter SD-WAN links to Microsoft Azure cloud, Office 365

Cisco and Microsoft this week extended their relationship to make it easier and more efficient for SD-WAN customers to set up and run direct Internet access to enterprise applications such as Office 365 and other Azure Cloud services.Specifically Cisco said it would integrate its SD-WAN package with Microsoft’s Azure Virtual WAN and Office365.  This amalgamation will let customers extend their WAN to Microsoft Azure Cloud and, in parallel, deliver optimized, secure Office 365 communications, according to Sachin Gupta, senior vice president, product management with Cisco’s Enterprise Networking Business.   To read this article in full, please click here

Delivering a Multi Cloud and Cloud Native Operator Experience

Right around the same time I joined Arista in 2009, Amazon Web Services developed the concept of the Virtual Private Cloud, one of the seminal technologies that became a core construct deployed throughout public clouds enabling enterprise customers to corral and protect resources and provision them into logical groups, align security policies, and simplify their management. Following this, Google developed a model for Virtual Private Clouds that spanned regions allocating one subnet per region by default - creating the first multi-region VPC within a single cloud provider.

Executing a Jinja2 Loop for a Subset of Elements

Imagine you want to create a Jinja2 report that includes only a select subset of elements of a data structure… and want to have header, footer, and element count in that report.

Traditionally we’d solve that challenge with an extra variable, but as Jinja2 variables don’t survive loop termination, the code to do that in Jinja2 gets exceedingly convoluted.

Fortunately, Jinja2 provides a better way: using a conditional expression to select the elements you want to iterate over.

Heavy Networking 483: SD-WAN Incompetence, Myths, And Fallacies

Managed Service Providers (MSPs) are trying to sell SD-WAN services by convincing you that you don't have the staff, training, or competence to operate an SD-WAN. On today's Heavy Networking, Greg Ferro and Ethan Banks pick this argument apart to see if there's anything to it.

Ansible vs. Nornir: Speed Challenge

When talking about Nornir and Ansible, speed is one of the topics that come up from time to time. A common argument for Nornir is that it performs better when working with either many hosts or lots of data. For some who hear this, it isn’t entirely clear what we mean. This article will look at some numbers. Recently I came across a quote by Kelsey Hightower that stuck with me.

“You haven’t mastered a tool until you understand when it should not be used.”

Let’s see if any of that can be applied here. Continue reading

Docker’s Recommended Sessions for KubeCon 2019

The Docker team is gearing up for another great KubeCon this year in San Diego, November 17-21. As a Platinum sponsor of this year’s event, we are excited to bring Docker employees, community members and Docker captains together to demonstrate and celebrate  the combined impact of Docker and Kubernetes.

Stop by Booth P37 to learn how to leverage the Docker platform to securely build, share and run modern applications for any Kubernetes environment. We will demonstrate Docker Desktop Enterprise and how it accelerates container application development while supporting developer choice. Experts will be on hand to answer questions about Docker Kubernetes Services (DKS), a secure and production-ready Kubernetes environment. Or come to learn more about Docker’s contributions to Kubernetes while picking up some great Docker swag.

Forrester: Edge computing is about to bloom

The next calendar year will be the one that propels edge computing into the enterprise technology limelight for good, according to a set of predictions from Forrester Research.While edge computing is primarily an IoT-related phenomenon, Forrester said that addressing the need for on-demand compute and real-time app engagements will also play a role in driving the growth of edge computing in 2020.[Get regularly scheduled insights by signing up for Network World newsletters.] What it all boils down to, in some ways, is that form factors will shift sharply away from traditional rack, blade or tower servers in the coming year, depending on where the edge technology is deployed. An autonomous car, for example, won’t be able to run a traditionally constructed server.To read this article in full, please click here

Extend Your Organization’s Reach with Software-Defined Wide Area Networking

Ashwath Nagaraj Ashwath Nagaraj is co-founder and CTO of Aryaka, responsible for building the company’s vision and technology since its inception in 2009. He previously founded Allegro Systems; a security startup acquired by Cisco in 2001. Ashwath was also a founder of Assured Access Technologies, which developed WAN access and aggregation products. AAT was acquired by Alcatel in 1999. He holds 17 patents in storage, security, architecture and networking. Business today moves at the speed of 1s and 0s, flashing through the internet into our computers, mobile phones, tablets and smart speakers. Digital Transformation is an undeniable driving force behind business success, and organizations that can’t adapt to the needs of their customers and the demands of their industry will get left behind. It has been eons (in internet terms) since just having a website was enough to be competitive. If your organization has mastered SEO, incorporated server virtualization, adapted to today’s mobile-first mentality — for both employees and customers — and are looking at the next step you can take to compete, SD-WAN is the next logical step. SD-WAN (software-defined wide area network) at first glance appears to be an almost impossible chimera of “cheaper, faster and better” at Continue reading

Announcing VMware NSX Distributed IDS/IPS

Six years ago, VMware pioneered the concept of micro-segmentation to stop the internal, lateral spread of malware. We then launched the NSX Service-defined Firewall, an internal firewall that’s built into the hypervisor, distributed, and application aware. Shortly thereafter we introduced NSX Intelligence to automate security rule recommendations, streamlining the deployment of micro-segmentation.

Now we are announcing that we will be taking internal security to the next level by introducing optional Intrusion Detection and Prevention (IDS/IPS) for our Service-defined Firewall. Built on the same philosophy, the new NSX Distributed IDS/IPS will allow enterprises to fortify applications across private and public clouds.

VMware’s Security Is Intrinsic. Here’s What That Means.

Intrinsic Security is security that’s built in, not bolted on. And that makes it better.

When security is bolted on, it’s never as good as built-in security. Imagine an apartment building where you add the alarm system, the security cameras, and the fire escape after the fact. It looks awkward and doesn’t work that well, either.

But when you design those things in upfront, the effect is completely different. Everything just works better, as parts of a whole system. The same thing is true for security.

More importantly, when you build in Continue reading
