Worldwide Cloud Computing Adoption - An Insight

Cloud Computing : Worldwide Cloud Adoption - An Insight

Author: Saumya Aggarwal

Service providers and IT vendors are all taking a crack at offering cloud computing services that leverage Software-as-a Service (SaaS, Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS) approaches to meet a wide range of business requirements. Some companies like Amazon, IBM, Sun Microsystems and Google are offering public clouds in which resources are dynamically provisioned on a self service basis over the Internet via web applications. On the other hand, some IT vendors like NaviSite, Rackspace and Terremark are offering cloud on private networks, which ensure greater security, corporate governance and reliability.

Since Cloud Computing is an evolving concept, IT vendors need to consider key components of the cloud computing strategies when making long term deals that may or may not include cloud services in present but might in the future. For example, IBM aims at delivering cloud services directly to clients and helps them create their own cloud technology environment. Similarly, HP is focused on developing cloud services for automated IT infrastructure, cloud implementation, social computing and web based services. TCS is still planning out a cloud computing strategy and focusing on the services to add for both public and private cloud environments.

Then there are some cloud computing vendors offering enterprises the chance to run not only business applications but also custom developed applications in the cloud – with greater flexibility to scale computing power. Most of the providers are either offering cloud services for clients via consulting, delivering cloud services (which can include aggregating services from other providers), or both. Clients should be clear about whether a particular service provider is implementing, managing, or delivering the services provided by external cloud providers or their own internal capability.

NaviSite has recently launched its powerful enterprise managed cloud services, NaviCloud to deliver infrastructure as on-demand, scalable, and usage billed services. NaviCloud combines the economies of scale of a public cloud with scalability and flexibility of an internal cloud to cater enterprise requirements for security, availability, flexibility, and performance. NaviCloud uses VMware\'s vSphere and Cisco\'s Unified Computing System to provide a robust enterprise-class cloud platform.
