IP Address Management: Smoothing the Way to Cloud-Based Services

Contributed by David Flesh, Sr Manager, Product Marketing, Cisco Network Management Technology Group

Many service providers today are implementing or investigating cloud computing to take advantage of its inherent operational advantages and as a platform from which to offer differentiated cloud-based services. By abstracting IT resources and services from the underlying infrastructure, service providers are achieving highly elastic, multitenant environments and savings. For example, cloud-based environments facilitate provisioning in minutes; time-to-market reductions of more than 50 percent; high server and storage utilization; 50 percent reductions in capital costs; and 25 to 30 percent reductions in operational costs. 1

At the same time, cloud-based services are highly attractive to providers’ enterprise customers. Service provider-based cloud services offer greater scalability and performance without requiring premises-based infrastructure and management. Self-service, scale-on-demand, and pay-per-use features increase user convenience and IT flexibility, while automated recovery and cloud-based backup significantly enhance risk management.

The good news is that service providers today are uniquely positioned to take advantage of cloud computing. Infrastructure as a service (IaaS) -- a cloud utility architecture -- provides an easy entry point for many service providers who are already expert at provisioning, managing, and scaling infrastructure-based services for multiple customers. IaaS helps enable service providers to increase return on investment through existing infrastructure and to deliver high-margin multitenancy services and support new competitive offerings. According to the Cisco Internet Business Systems Group, a 2009 study has forecast IaaS service revenues to be approximately $15.6 billion by 2013.

An important element of successful cloud-based offerings is fast, efficient provisioning and service delivery. However, as IP addressing becomes much more complex, providers will need a new, easier way to manage IP addressing and multitenant services.

  1. Thanks Stephen for sharing this. You name many advantages of cloud-based services. But where are the disadvantages? Is it really needed? I’m a pessimist in this respect, so where is the hook?

  2. Oliver, this is an interesting request—as there are always many points of view and, in reality, cloud-based services may not be the “right” solution for every situation.

    Some network operators may claim that they are giving up control when moving to a cloud-based computing solution. They might also claim that they would be giving up business flexibility. Both issues talk to an established process or business model –a model with which companies and the network operators within them have become comfortable. In an established model like this, change in and of itself might be considered a disadvantage. The reality for some companies is they aren’t ready for cloud computing. That’s okay. When their organization or situation changes due to operating expenses, anticipated upgrade requirements, or business model they can revisit cloud computing.

    Cloud computing draws on a number of technologies such as, software as a service (SaaS), distributed computing, multi-tenancy and virtualization. As a result some organizations worry that one or more of these services may not offer the maturity they need to confidently move to a cloud-based solution. In this situation it is important that the provider offer best-in-class components that have been tested and proven to address this concern.

    Finally, cloud- based providers differ in what and how they implement. Verifying compliance capabilities, e.g., HIPAA and Sarbanes-Oxley, backup and restore capabilities, and security support are vital to a successful implementation.
