Worth Reading: The old switcharoo

The cost of servers keeps going up and up, thanks in large part to memory, flash, and GPU prices rising as too much demand chases too little supply and also due in part to the rising cost of processors. So the server market is booming. And guess who is actually paying for it? Network vendors, who are being ground down like sacks of wheat in the massive granite grist mill of intense competition. —Timothy Prickett Morgan @The Next Platform

Data freshness, not speed, most important for IoT

The age of sensor data is more important than how fast it takes that information to travel around Internet- and Location-of-Things environments, say some experts. Scientists are, in fact, rethinking the network because of it.“It’s not enough to transmit data quickly. That data also needs to be fresh,” says MIT in a news release.The university has been working on better ways to ensure that sensors, which distribute readings for analysis, provide the most salient stuff. It’s not easy because you can’t just send everything at the same time (an obvious solution) — there isn't enough bandwidth.To read this article in full, please click here

IDG Contributor Network: Enterprises evaluate the costs of building versus buying an IoT platform

Almost every week we speak with an enterprise that is curious about building its own IoT application enablement platform (AEP) or IoT device management (DM) platform. The idea is straight-forward – an enterprise wants total control over the technology it deploys, so it chooses to hire developers to build the perfect, inexpensive platform.Then what happens? Sometimes everything goes exceedingly well and the IoT platform delivers as anticipated. Other times, the enterprise determines it takes more time and money to build a platform that anticipated it takes more staff to support the platform on-going than anticipated it is very hard to keep the platform features up-to-date compared to the features offered from best-in-class vendors’ IoT platforms the initial in-house platform was great, but scaling and modifying the platform to meet future requirements is exceedingly difficult due to the chosen platform architecture So, what are the total enterprise costs of building an enterprise-grade IoT platform versus buying IoT platform services from a third-party AEP or DM vendor? It really depends on the IoT solution that the enterprise wants to deploy.To read this article in full, please click here

We’ve Added Another Blockchain Course To Our Video Library!

 

This Course is By Joseph Holbrook and is 4 hours and 34 minutes long. You can view the full course on our streaming Site, or buy the course at ine.com.

A blockchain is a tamper-evident, shared digital ledger that records transactions in a public or private peer-to-peer network. Distributed to all member nodes in the network, the ledger permanently records, in a sequential chain of cryptographic hash-linked blocks, the history of asset exchanges that take place between the peers in the network. This course has been designed for technical architects, pre sales architects, developers and project managers who must make technical decisions about distributed architectures and development platforms.

Cisco developer push yields 500,000 DevNet members working on programmable networks

ORLANDO – Cisco’s developer program, DevNet, is on a hot streak.Speaking at Cisco Live 2018, DevNet CTO Susie Wee said the group, which was founded in 2014, now has 500,000 registered members."That’s a pretty cool milestone, but what does it mean? It means that we've hit critical mass with a developer community who can program the network," Wee said. "Our 500,000 strong community is writing code that can be leveraged and shared by others. DevNet is creating a network innovation ecosystem that will be the hub of the next generation of applications and the next generation of business."At Cisco Live the company also announced it has expanded the DevNet world to include:To read this article in full, please click here

Start with Business Requirements, not Technology

This is the feedback I got from someone who used ExpertExpress to discuss the evolution of their data center:

The session has greatly simplified what had appeared to be a complex and difficult undertaking for us. Great to get fresh ideas on how we could best approach our requirements and with the existing equipment we have. Very much looking forward to putting into practice what we discussed.

And here’s what Nicola Modena (the expert working with the customer) replied:

As I told you, the problem is usually to map the architectures and solutions that are found in books, whitepapers, and validated designs into customer’s own reality, then to divide the architecture into independent functional layers, and most importantly to always start from requirements and not technology.

A really good summary of what ipSpace.net is all about ;) Thank you, Nicola!

Network Labs Using Nested Virtualization in the Cloud

Many open-source network simulation and emulation tools use full virtualization technologies like VMware, QEMU/KVM, or VirtualBox. These technologies require hardware support for virtualization such as Intel’s VT-x and AMD’s AMD-V. To gain direct access to this hardware support, researchers usually run network emulation test beds on their own PCs or servers but could not take advantage of the inexpensive and flexible computing services offered by cloud providers like Amazon EC2, Google Compute Engine, or Microsoft Azure.

By August 2017, most of the major cloud service providers announced support for nested virtualization. In the cloud context, Nested Virtualization is an advanced feature aimed at enterprises, but it is also very useful for building network emulation test beds. I’ve written about nested virtualization for servers before but, until recently, I was limited to running nested virtual machines on my own PC. Now that the major cloud providers support nested virtualization, I can build more complex network emulation scenarios using cloud servers.

This post will discuss the cloud service providers that support nested virtualization and how this feature supports open source networking simulation and emulation in the cloud.

Off the Cuff – Microsoft Aquires GitHub

On June 4, 2018, Microsoft announced it will acquire GitHub for $7.5 billion.  What does this acquisition mean for developers, the projects that use GitHub, and the online community surrounding it?  Listen is as Network Collective discusses with this acquisition means for Microsoft, GitHub, and the many projects and developers that rely on GitHub.

Automation critical to scalable network security

Securing the business network has been and continues to be one of the top initiatives for engineers. Suffering a breach can have catastrophic consequences to a business, including lawsuits, fines, and brand damage from which some companies never recover.To combat this, security professionals have deployed a number of security tools, including next-generation firewalls (NGFW) such as Cisco’s Firepower, which is one of the most widely deployed in the industry. Managing firewalls becomes increasingly difficult Managing a product like Firepower has become increasingly difficult, though, because the speed at which changes need to be made has increased. Digital businesses operate at a pace never seen before in the business world, and the infrastructure teams need to keep up. If they can’t operate at this accelerated pace, the business will suffer. And firewall rules continue to grow in number and complexity, making it nearly impossible to update them manually.To read this article in full, please click here
