4 Steps For A Smooth SDN Installation
SearchDataCenter, September 5th, 2019
Software-defined infrastructure can be tricky to implement. Automation, vendor-supported hardware and skilled developers are essential for smooth updates

"Software-defined networking allows organizations to drive more automation and programmability into the network, which can simplify management.

Even with adoption concerns, organizations have a great need for network orchestration, and the basic concept of software-defined networking (SDN) is sound -- especially for shops that use virtualization, cloud, containers or microservices..."

Take your privacy and security seriously enough to avoid malware, ad tracking and slow connections

"Think of a good virtual private network (VPN) like a bodyguard for your bank account. When you go for a stroll through the bustling lanes of public Wi-Fi, your VPN shields you from password pickpockets and keeps you out of unsafe areas. You trust your VPN -- a set of technologies that link computers together, then encrypt your data as you browse online -- with your most precious information, and maybe even your family's. So when a VPN provider offers to guard your digital life for free, the first question you should ask yourself is: What's in it for them?..."

With help from artificial intelligence and automation, client VPN technologies could innovate the way they handle data flows within hybrid cloud environments

"Traditional client VPNs are growing long in the tooth. They are cumbersome to set up and manage and often create data flow inefficiencies. Because of this, many believe client VPNs will soon be a thing of the past. But, despite obvious flaws, client VPN technologies remain highly relevant. That's why client VPNs will more likely evolve rather than disappear..."

Why SD-WAN Is Taking Over Enterprise Networks
Data Center Knowledge, September 3rd, 2019
The traditional connectivity model doesn't work for today's distributed enterprises

"One of the fastest growing enterprise networking technologies, SD-WAN can simplify network management and optimize connections to cloud services.

Leased-line and MPLS connectivity can serve your head office well, but for small branch offices and remote workers using SaaS applications the public internet is often the only option. They could be customer service agents working from home, first responders on scene, or travelling executives all using latency-sensitive voice and video services - something traditional enterprise WANs struggle to support..."
