New technologies keep on coming, but which are better to invest in now versus later? CompTIA's recently released a prioritized list of top 10 emerging technologies.
One of my readers sent me a series of questions regarding a new cloud deployment where the cloud implementers want to run VXLAN and EVPN on the hypervisor hosts:
I am currently working on a leaf-and-spine VXLAN+ EVPN PoC. At the same time, the systems team in my company is working on building a Cloudstack platform and are insisting on using VXLAN on the compute node even to the point of using BGP for inter-VXLAN traffic on the nodes.
Using VXLAN (or GRE) encap/decap on the hypervisor hosts is nothing new. That’s how NSX and many OpenStack implementations work.

But time has changed now and with introduction of automation ,SDN ,Devops in networks professional life has made him to come out of windows environment and try Linux for multiple reasons as below:
So when ever we plan to work on linux environment , we just start downloading ubantu on our windows laptop with VM box ..install both and start working.
But there is an environment known as Vagrant that will not help you do all the Linux related task but also provide an environment that helps reduce setup time and allows you to virtualize configurations for various projects.We can set up up a virtual network environment for testing purposes, or setting up a lab, work with python , ansible ,devops tools and much more .

We built Access to solve a problem here at Cloudflare: our VPN. Our team members hated the slowness and inconvenience of VPN but, that wasn’t the issue we needed to solve. The security risks posed by a VPN required a better solution.
VPNs punch holes in the network perimeter. Once inside, individuals can access everything. This can include critically sensitive content like private keys, cryptographic salts, and log files. Cloudflare is a security company; this situation was unacceptable. We need a better method that gives every application control over precisely who is allowed to reach it.
Access meets that need. We started by moving our browser-based applications behind Access. Team members could connect to applications faster, from anywhere, while we improved the security of the entire organization. However, we weren’t yet ready to turn off our VPN as some tasks are better done through a command line. We cannot #EndTheVPN without replacing all of its use cases. Reaching a server from the command line required us to fall back to our VPN.
Today, we’re releasing a beta command line tool to help your team, and ours. Before we started using this feature at Cloudflare, curling a server required me to Continue reading
By now the story and resulting controversy is as much about media credibility as it is about cyber — and national — security.
