The document discusses the critical role of network design in cloud computing, emphasizing that poor connectivity can lead to performance issues for enterprises. It outlines the importance of a robust communication layer for various cloud service models and highlights the need for businesses to recognize the significance of their network infrastructure. Additionally, it details a hybrid cloud setup with enterprise IT management and mentions several data centers that provide high-speed connectivity.

Network Virtualisation

2. Is Your Network Design the Weak Link in Cloud Computing?
“Through 2013, at least 60% of enterprises will
experience slow or inconsistent application
performance issues from externally placed
applications, due to improper network design”.

3. Cloud Connectivity: Carefully does it
“Connectivity is not widely perceived to be a major barrier to
the adoption of Cloud services”.
“But experience of Cloud highlights that in reality connectivity
can be a significant challenge”.

4. Telecom’s Central Role In Cloud Computing
“Without a robust communications layer, the concept of
cloud computing is a nonstarter”.
“All three dominant flavors of cloud computing –
infrastructure-as-a-service (IaaS), software-as-a-service
(SaaS), and platform-as-a-service (PaaS) – depend on fast,
efficient, reliable communications”.

5. “The network is often the forgotten
piece in the rush towards
virtualisation”.
“Raising the importance of the
network in the consciousness of the
business, is not an easy task……
The business just doesn’t get it”
Clive Longbottom, head of research at Quocirca
