On several recent occasions, in discussions with my customers, colleagues and industry peers, the importance of the network, as it relates to Cloud Computing and Data Centers, has been challenged. I am surprised that such a topic is even up for debate ! In my opinion, the underlying network infrastructure of any given Data Center is the architectural foundation for service and application strategy; be it Cloud Computing, Virtual Desktops, Video or even Hosting services.
If we look at a broader scale, no one can argue the complexity and at the same time, the intelligence the modern Internet brings to it’s consumers. How would enterprises and service providers alike, offer converged services like voice, video and data without any network intelligence ? Not to mention, security, application scaling and other managed services. Networks are no longer the traditional packet switching platforms, it’s the heart and soul of intelligence which integrates with other intelligent applications to differentiate the multitude of services that can be enabled over a common medium. As application requirements are increasingly becoming complex, the need for equally smarter transport is critical.
Virtualization is bringing a whole new perspective to this discussion. It’s true you can account for network, compute and storage virtualization within a given solution; virtual switch, virtual machine, virtual firewall, virtual load-balancer, etc.; but how far can we abstract the network ? One can absolutely argue, Cloud Computing is server/compute resource centric, however for most enterprises, when you combine this compute structure with application workload requirements from business, technology and operations perspectives, suddenly the foundation architecture plays a crucial role -- i.e. the network and it’s interconnects.
We continue to see our service provider partners leverage the economics and agility of cloud services
Today, AT&T announced the availability of its Unified Communications Service, a new way for its business subscribers to offer a complete collaboration suite of features to employees in a secure and cost effective way. AT&T’s enterprise collaboration solution features Cisco’s own Hosted Collaboration Solution, which gives partners, including service providers and integrators, the ability to deploy multiple collaboration applications on one server in a virtualized environment and then host those applications for multiple client organizations.
Cisco’s cloud services ultimately enable our service provider partners to offer a seamless experience for both their enterprise and end-user customers. For further details, check out the full announcement.
Cloud computing—delivering infrastructure, services, and software on demand via the network—offers attractive advantages to the public sector. For example, it has the potential to reduce information and communications technology (ICT) costs by virtualizing capital assets like disk storage and processing cycles into a readily available, affordable operating expense.
One of the most significant cloud computing opportunities for the public sector is the ability to share ICT resources among multiple agencies. While governments have tried hard to create frameworks geared toward shared services, these have not always been successful. Cloud computing offers an easier and less burdensome route to more efficient and effective public sector information management.
Of course, cloud computing is not without its challenges:
A service provider residing outside of a government’s legal or territorial jurisdiction may put access or security at risk.
Open standards and interoperability may not be guaranteed, leading to the risk of vendor lock-in.
Data privacy is a concern when using public clouds. This can be addressed by the development of private clouds.
Business continuity will continue to be a concern. Cloud computing, however, may also mitigate this risk, as cloud vendors are likely to use more robust and better-maintained computing platforms that provide more redundancy and are less likely to fail.
‘Twas the week before Christmas, when all through IT, not a creature was stirring, not even a sysadmin?
Well, not quite. To support the global operations for a Fortune 100 company, the IT staff are always stirring things up at Cisco. But they may be just a little less busy this holiday season. Why? Because Cisco IT deployed a private cloud earlier this year, with a self-service portal and automated provisioning for infrastructure-as-a-service.
This means that employees throughout Cisco can provision and manage the infrastructure resources they need on their own, anytime and anywhere – so our sysadmins can take a break this holiday season (or more likely, they can focus on other IT priorities).
Management capabilities are key to the delivery of private, public, and hybrid cloud services, providing scalability, reliability, security, and economic feasibility. Learn about recently announced new management capabilities in Cisco Hosted Collaboration Solution (HCS) from Eric Schoch, leader of the Cisco HCS product teams. Eric shares how management enhancements are targeted at providing greater visibility and faster resolution of issues, resulting in better service level agreements and more scalable, economical operation benefiting both customers and partners. Eric also touches on what the future will bring in the area of management.
Before and after our Cisco Hosted Collaboration (HCS) announcement, we conducted a series of interviews with members of Read More »
