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. The work done by the Open Network User […]

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 […]

CloudStack Competition Endangers Enterprise Open Source Adoption

When disruptive cloud architectures began to shake corporate IT foundations, it required a ‘cloud stack’ to create, manage, and deploy infrastructure cloud services. Today, such stacks are available from a wide range of providers, some use proprietary code, but increasingly corporate users are adopting open source products. However, like other disruptive paradigms, most cloud deployments […]

The Growing Need For Intelligent Workload Management

Life used to be so good. An operating system was loaded onto a server of some sort and an application stack loaded on top of that. Provided the workload remained pretty static, the performance was pretty much guaranteed. The problem was that most workloads weren’t static. As such, resource ceilings were often hit, and the […]

Is NFV Just for Service Providers?

A lot of people that I talk to regard NFV as something of interest only to service providers. I think that perception comes in large part from the service provider orientation of some of the high-visibility organizations that have formed to drive the evolution of NFV. This includes an industry specification group (ISG) that the […]

The Holiday Internet Weather Map

Holiday shopping may be behind us, but Internet weather is still very much here. The fluctuations in latency and packet loss that can disrupt the cloud, and for that matter Internet shopping, continue to be a vital consideration in any network architecture. To find the extent of its impact, Silver Peak documented Internet weather patterns […]

Cyber Monday: Rough Weather Interferes with the Cloud

E-tailers weren’t the only ones grumbling on Cyber Monday. Enterprise users felt the effects of the online sales crush as North American Internet delays to leading SaaS providers increased by as much as 363 percent. This was the latest finding of an extensive research project conducted by Silver Peak and two leading Internet researchers into […]
