Alternatives to Nmap: from simple to advanced network scanning

This month marks the 20th anniversary of Nmap, the open-source network mapping tool that became the standard used by many IT professionals, but that can be a bit much if you only need to do general network maintenance and are intimidated by its command-line interface.There are alternatives – not many – that range in technical sophistication from tools with GUIs that can ease you into performing the essentials of network maintenance to more advanced software that is similar to Nmap itself.[ Also see reviews of Icinga, Observium, Nagios and Zabbix network-monitoring software.] Like Nmap, all these network tools are free.To read this article in full, please click here

Adjusting System State with Infrastructure as Code

This is the second blog post in “thinking out loud while preparing Network Infrastructure as Code presentation for the network automation course” series. If you stumbled upon it, you might want to start here.

An anonymous commenter to my previous blog post on the topic hit the crux of the infrastructure-as-code challenge when he wrote: “It's hard to do a declarative approach with Ansible and the nice network vendor APIs.” Let’s see what he was trying to tell us.

IDG Contributor Network: Are you seeing what I’m seeing?

Enterprises are investing in their networks at an accelerating rate. As legacy IT on-premises infrastructure gives way to hybrid cloud and virtualized environments, and an escalating data tsunami drives data center expansions, increasing investments of time and money are raising the stakes ever higher. Unfortunately, end users’ expectations for service are growing as well, piling additional demands onto network operators and engineers who are already wrestling with network migration challenges.Yet despite the fact that the enterprise networking environment is rapidly changing, IT support teams are still using the same network performance metrics to monitor their networks and evaluate whether or not service delivery is up to par. The problem is that they’re using a one-dimensional tool to measure a subjective experience that tool was not designed to even understand, much less aid in troubleshooting.  It’s kind of like trying to tighten a screw with a hammer.To read this article in full, please click here

Vapor IO secures new funding for major U.S. rollout

Vapor IO, the edge computing specialist that builds mini data centers for deployment at locations such as cell phone towers, has secured Series C financing, which the company says will help accelerate the deployment of its Kinetic Edge Platform as a national network for edge colocation.Vapor IO has been all about developing a model for a distributed network of edge colocation sites, with micro modular data centers in containers about the size of a shipping container. The company had been working with Crown Castle, the nation’s largest provider of shared wireless infrastructure, on an edge collaboration project under the name Project Volutus.Vapor IO has now acquired the assets of Project Volutus from Crown Castle and will offer it under the brand name The Kinetic Edge. It uses both wired and wireless connections to create a low-latency network of its colocation sites, allowing cloud providers, wireless carriers and web-scale companies to deliver cloud-based edge computing applications via its data centers.To read this article in full, please click here
