As most are ... Read More
Veriflow 2019 Predictions: Multi-Cloud Environments and Intent-based Networking

Feed: Blog – Veriflow. Author: Brighten Godfrey; Originally published on VMblog’s annual prediction series Taking a broad view across the enterprise, both cloud computing and intent-based networking deployments are still young and many enterprises are just taking the first steps. Looking ahead to 2019, these deployments will mature as they expand and become increasingly complex. On predicting challenges in the cloud: As enterprises become more reliant on cloud, the complexity of these deployments will deepen – involving many virtual private clouds, interconnections and segmentation between components, and hybrid cloud connecting on-premises and multiple public cloud deployments. According to a recent ... Read More
Automation of network-wide intent verification using the Veriflow API

Feed: Blog – Veriflow. Author: Avoy Nanda; Humor courtesy of xkcd Network infrastructure teams are constantly asked to support more business requirements, and do so more quickly, while maintaining high uptime. One of the most difficult aspects of meeting these needs is that the network is very complex, and engineers have no way of quickly and reliably verifying that such network changes don’t have any unintended consequences. With this in mind, network infrastructure teams today are looking to add more automation to their networks and thus avoid costly and time-consuming manual checks that only verify a small fraction of their ...

Real world lessons in protecting your network– A comprehensive way to verify network behavior
Feed: Blog – Veriflow. Author: Benjamin Mourad; Networks today are not neat and simple, with clear hierarchies. Users, networks, data, and applications are becoming more distributed; security boundaries are more amorphous; and changes occur more quickly over time. In addition, data today is exchanged and shared with multiple partners and with Internet of Things (IoT)-enabled devices, which are continuing to grow in popularity. IoT creates a greater need for IPv6, which can improve security but also adds complexity, given the large address spaces it requires. Networks today are also multi-vendor, have grown organically over time, and traditionally are poorly documented ... Read More
WannaCry: Taking a defense in depth approach | Veriflow

Feed: Blog – Veriflow. Author: Brighten Godfrey; Ransomware is top of mind again with the rapid spread of the WannaCry malware, which has spread across the Internet encrypting users’ files and demanding $300 in Bitcoin before decrypting them. Even after a lucky fix slowed it down, the infections continue and new variants can be expected. This is a time to reflect: what could enterprises who critically depend on their networks do to protect themselves from such digital pandemics? How can we adopt a defense in depth approach? First, let’s take a step back and ask, how does WannaCry spread? Take an ... Read More
Veriflow as a Platform: Building Applications Using Veriflow APIs | Veriflow

Feed: Blog – Veriflow. Author: Firat Kiyak, Senior Software Engineer; In today’s networking world, a wide variety of technologies at different layers are applied to solve problems: high availability, load balancing, address translation, access control, packet forwarding and traffic engineering to name a few. Due to this large problem and solution space, it does not take much time to realize that every network is truly unique. Computer networks are heterogeneous and complex, and existing network administration and operation tools are either too generic to the point it merely becomes useful for everyone or is too specific to the point it ...

What is cool? | Veriflow

Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; Helping network operators be agile while eliminating outages and vulnerabilities Last week we were named to Gartner’s Cool Vendor report for Enterprise Networking. I’d like to think we are cool because we have a team made up of the top computer scientists and engineers from around the globe. But the reason we are cool, why we get out of bed every day, and why we think Gartner named Veriflow to their “Cool Vendor” list is because we are helping the networking industry evolve in the design and automation of ...

It’s Time to Have an Honest Conversation with Your Network | Veriflow

Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; Network design has been a one-sided affair. As engineers and network operators/architects we come up with an idea based on need, and we sit down to create the ideal network. But then something happens, as we go to implement the network we have a breakdown in communication. We have no way to ask the network if it is going to be able to out carry our design. This failure to communicate is causing all kinds of issues, whose effects usually show themselves as deteriorations in performance, network outages, and ... Read More
Big AWS Outage: Is Your Network at Risk? | Veriflow

Feed: Blog – Veriflow. Author: Milind Kulkarni; Can we prevent network outages, before they happen? Major AWS Outage: The recent AWS outage was so big and lasted so long that it affected thousands of Amazon customers that depend on AWS infrastructure. Some even tweeted that “half of the Internet was down due to the outage.” Amazon deserves kudos for being transparent about this incident (and many prior incidents) by releasing detailed analysis of what caused the outage. Amazon described that the outage was caused by human error, when an incorrect command was entered that accidentally took more servers offline than ... Read More
