There will be no single cloud delivery model for fulfilling business needs as enterprises will require a private cloud for secure applications and use customer-facing applications on the public cloud. There is also the virtual private cloud hosted outside of customer premises but essentially offers a higher level of security and regulatory compliance than a public cloud.
In fact, 69 percent of organisations in Asia Pacific and Japan surveyed in a study commissioned by HP said that they intend to pursue a hybrid cloud delivery model. Hybrid models enable organisations to maximise their existing infrastructure and retain internal control while also being able to use public cloud resources where required.
Cloud computing will further open up a myriad of cost-effective alternatives to traditional means of IT. An example is the use of cloud to offer disaster recovery as a service. This reduces the need for companies to invest in data centre facilities, IT infrastructure and manpower, thereby significantly reducing costs. At the same time, it lowers the barriers of entry for SMBs to tap disaster recovery to ensure their ability to provide a minimum standard of service.
In the public sector space, the Infocomm Development Authority had awarded a tender for the country's Government cloud (G-Cloud) and launched new initiatives. To be built on HP's CloudSystem, G-Cloud will enable government agencies to scale up their IT infrastructure with cloud services rapidly without having to make any significant hardware or software investments. They can respond internally and to the general public with greater agility, deliver improved e-services more efficiently and manage IT costs more effectively. HP is proud to be partnering SingTel in implementing a private cloud computing infrastructure for G-Cloud, the first extensive private cloud for all government agencies in Singapore.
Initially, many organisations looked at cloud computing as a way to optimise their infrastructure. As their comfort level with cloud usage increases, they will look at application outsourcing, and at addressing non-core functions such as disaster recovery service and back-up as core functions. The high speed offered by Singapore's Next Generation Nationwide Broadband Network (Next Gen NBN) will also serve as a boost.
As IT departments work on providing faster response to new service requests, they will want to make the cloud easier to deploy and consume. To achieve this, users will be able to directly request their own cloud resources in simple steps through the use of a portal. The IT department will have to build a workflow for how resources are allocated and managed, and ensure governance and service-level agreements are aligned with this model. Most importantly, as with any change in how technology is provided and consumed, change management will need to be in place.
