You are probably thinking that CITEIS is a typo – but it’s not. In fact, CITEIS stands for Cisco IT Elastic Infrastructure Services and it’s the name that Cisco’s IT department coined for our internal private cloud.
You can read more about CITEIS here, including an explanation of the two options: CITEIS “Express” for on-demand access to virtual compute resources from a shared pool of resources; and CITEIS “VDC” (Virtual Data Center) to provision your own virtual data center with a reserved pool of compute, storage, and network capacity.
We recently recorded a brief demo video of the Express version so you can see how it works:
IT shops deploying clouds over the past year have been focused on Infrastructure as a Service ( http://en.wikipedia.org/wiki/Infrastructure_as_a_service#Infrastructure ) as a way to drive speed in virtual and physical server provisioning, cost savings in operations, proactive service level agreements, and increased control and governance. In one of my blogs I introduced our Cisco Intelligent Automation for Cloud http://blogs.cisco.com/datacenter/the-secret-is-now-out-you-can-simplify-cloud-deployments-with-cisco-unified-management/ and how that addresses both private, hybrid and public clouds IaaS. Key to this is the service catalog and self service portal. Moving to cloud is NOT about taking hundreds of server configuration templates and moving to them immediate self service. All you are doing in that model is automating VM sprawl. They key is defining a limited set of services and options that your end users such as application owners and technical folks can order through a self service portal and manage their life-cycle.
I have talked to many enterprises that want a private cloud; also service providers that want to build a public cloud based upon Cisco UCS / Nexus. They all would like to get to their first generation of cloud very quickly. We have many conversations on infrastructure to use, the right choice of hypervisor, and what use cases to start with. Today I talked to a customer of our Cisco Intelligent Automation for Cloud that wants a differentiating end user portal. Everyone can spin up a VM, but how to do it in a way that will drive adoption and new business, whether it is for the enterprise or service provider? How do we do this at a cost and a timeline that meets the needs of the business and the CIO.
These are not lightweight concerns. I have seen many data center automation projects that focused too much on the provisioning and not enough on the end user experience. The Intelligent Automation Solutions Business Unit at Cisco has been involved with many customers building private and public clouds with our software stack. This includes Cisco IT’s very large private cloud deployment based upon our software. The two services they deployed: CITEIS (Cisco IT Elastic Infrastructure Services) Express and CITEIS VDC (Virtual Data Center) has received broad acclaim. Watch the following videos by Jamie MacQuarrie of the Intelligent Automation team on these two CITEIS Services.
Today, we ‘re featuring a guest post from Brian Blatnik, a senior manager within Cisco’s Collaboration Technology Group:
In the month since our CloudVerse announcement the notion of a world of many clouds – public, private, and hybrid – has resonated with our customers, partners, and industry analysts. I’d like to share some perspective on how those types of clouds address different customers in the collaboration cloud services market. Since last month’s announcement highlighted our private cloud model in that market, Hosted Collaboration Solution for Large Enterprises, I’ll focus on that model. As a reminder, the Cisco Hosted Collaboration Solution 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. The solution is designed to be run from partner data centers.
I’m often asked, “Haven’t enterprise voice and other UC services always been delivered from what we now call a private cloud?” It’s true that IP PBXs and other UC servers, like their PBX predecessors, provide services to users from a remote room or facility via a network. But there are two ways in which today’s cloud service delivery differs. First, there is the efficiency of pooling computing, network, and storage resources across multiple locations and services. Second, the services can be delivered in an on-demand fashion with elastic scaling.
The financial and strategic benefits deriving from these two factors are leading many businesses to consider consuming collaboration services in a utility model from Cisco’s partners in the Hosted Collaboration Solution (HCS). But the same drivers can result in substantial benefits to businesses that aren’t looking for services from a third party’s public cloud. Read More »
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.
