SD-WAN: Controller and Router Placement
Before you deploy SD-WAN, you need to decide where you want to place the controllers and edge routers.
4 Emerging Wireless Standards To Watch
A look at what's ahead in WiFi, including the speedy 802.11ax and HaLow for IoT connectivity.
Workflow Enhanced Networking (WEN)
Software Defined Networking (SDN) offered lots of hope, a centralized control-plane, programmable network functions and authenticated network nodes. Once we all stopped laughing and rolling around the floor with rib ache, the reality of SDN dawned quickly. It was a nice academic thought and set of experiments, but for the masses, the original meaning of SDN has changed significantly. The software giants with mountains of cash will drive technology like this early and possibly pave the way for the rest of us eventually, but for the masses of enterprises that vendors serve and that have more immediate requirements, SDN isn’t something that’s had massive adoption. The question of ‘why’ is a pretty obvious place to start and you don’t have to look too far before you find answers.
I will not get in to the overlay and underlay arguments here. These have been done to death already. Lots of organizations and vendors offer various takes on the middle-ground, far left and far right. This isn’t a product pitch either.
This post is around the “next onwards step” as opposed to changing the world. I also ‘feel’, this is the natural pull as opposed to the industry push we’ve come to Continue reading
Have to choose between VMware NSX and Cisco ACI? You’re Not Alone
I keep getting questions along the lines of “should I go with VMware NSX or should I deploy Cisco ACI” every single week, and as you know it’s hard to answer anything but it depends without spending hours on the topic.
That’s exactly what we plan to do in Zurich next Tuesday (May 16th) in a DIGS workshop that will run in parallel with the Data Center & Cloud Day (part of the SIGS Technology Conference).

We are excited to add four new data centers this week to Cloudflare's growing network, beginning with Colombo, Sri Lanka. This deployment is our 112th data center globally, and our 38th in Asia.
Faster Performance

Six million Internet properties using Cloudflare are now even faster across the island country of Sri Lanka. Previously, local visitors to Cloudflare customers were served out of our Singapore or Dubai data centers.

Sri Lanka added over one million Internet users in the past year alone. At ~30% Internet penetration, there is considerable room to grow.
Next Three Cities
Our deployments to be revealed later this week will provide additional redundancy to existing facilities in North America and Africa.

Impatient For Fabrics, Micron Forges Its Own NVM-Express Arrays
There may be a shortage in the supply of DRAM main memory and NAND flash memory that is having an adverse effect on the server and storage markets, but there is no shortage of vendors who are trying to push the envelope on clustered storage using a mix of these memories and others such as the impending 3D XPoint.
Micron Technology, which makes and sells all three of these types of memories, is so impatient with the rate of technological advancement in clustered flash arrays based on the NVM-Express protocol that it decided to engineer and launch its own product …
