Eight Best Practices For Cloud Security

There’s been a lot of FUD spread around in recent years on the subject of the public cloud. But as often happens in technology, convenience trumps security as far as users are concerned, and cloud services are just too convenient to turn down. Whether it’s to access your work files from home, to speed up […]

Cloud Islands & Fantasy Islands: Addressing the Cloud’s Dark Side

Remember the TV show Fantasy Island? The late 70s/early 80s show would start with a character named Tattoo shouting “The plane! The plane!” and pointing to the sky at a plane coming to the Island filled with a bunch of people looking to fulfill a fantasy. The other main character, Mr. Roarke (aka Khan Noonien […]

What Is A Next-Generation WAN?

In one of my last two blogs I discussed how a software defined WAN will automate the configuration of WAN edge routers and enable a WAN with multiple links to automatically reallocate traffic based on changing network conditions. In the other I discussed some of the WAN design options that the Open Networking User Group […]

Internet Connections Can Be Used For More Than Best Effort Traffic

The topic of WAN transformation is certainly nothing new, but the shift to mobile and cloud computing is making the evolution of the WAN something businesses must make a priority. Prior to being an analyst I ran some fairly large WANs, and for as long as I can remember there has been talk of trying […]

Six Pitfalls To Avoid In The Hybrid Cloud

It’s prediction season for the year ahead, and one of the most popular forecasts this time is that 2015 will be when hybrid clouds become practical. This isn’t one of those forecasts that come around time and again though – like “this is the year of desktop Linux” – no, this one is pretty solid. […]

Addressing Business Outcomes Through The Intercloud

At this year’s Cisco C-scape EMEAR analyst event, the vendor downplayed its hardware product launches, focusing instead on its rapidly evolving business credentials. Cisco, with its oft-repeated message of massive Internet traffic growth, talked this time about business outcomes, and delivering all the elements – hardware, software, and professional services — to make that happen. […]

Speeding up Network Provisioning

You probably know the problem already. The business is opening up a new office; has acquired a new company or wants to move a group of people from Place A to Place B. They have finally got around to letting IT know that it will happen – and they want you to wave your magic […]

Operational Challenges Continue To Plague Legacy WANs

This site, like many others, has focused on the need to evolve the WAN. Much of the value proposition for the shift to a hybrid WAN is to improve application performance, which is often poor over WAN. However, the challenges with a legacy WAN go beyond application performance. Operational issues are as big or a […]

Security-Focused Shift to SD-WAN Threatens DC Supremacy

Enterprise adoption of the Software-Defined Wide Area Network (SD-WAN) architecture opens up significant improvements from an operations, cost, and flexibility perspective. But it’s a big forklift infrastructure shift, where company size, and thus network complexity, are crucial factors in any decision to embark on the SD-WAN journey. What Will Drive SD-WAN Adoption? The work done […]

Here Comes The Petabyte Event Horizon

A step change is on the way for data storage, and in particular for networked storage. Technologies that have served us well for a decade or more are about to run out of steam, and the point-of-no-return looks to be when you start counting in petabytes rather than terabytes. If there is one thing that […]
