How to choose the "cloud" for you?
Although cloud computing is very hot, not all businesses have to migrate to the cloud, in fact, only a handful of companies and organizations to migrate their IT to the cloud, there are a lot of reasonable reason to make the enterprise more willing to use on-premise (local deployment, that is, the user to import the appropriate data to cloud computing platform) model, after all, many companies want to be able to have full control over their data.
From the point of view of the situation, now enterprise CIOs and CTOs are difficult to reject the cloud computing to play their hands, based on cloud computing to construct it ability to its flexibility, cost and production efficiency advantage is can not be ignored. Enterprises are faced with the choice, that is, there are more than one cloud model and cloud providers for the user to choose from, to make a reasonable choice, you should be familiar with many key factors before making any decision.
For the IT leader in the enterprise, the challenge is to continue, for example, in the face of cloud computing:
The traditional IT on-premises resource construction and architecture is a good way to protect the investment?
Does this approach facilitate the rapid use of emerging tools and promote more effective approaches and technological innovation?
How can we effectively control the proprietary / strategic IT assets and to find ways to make our IT investment more effective as soon as possible?
Find the best application
IT asset management strategy is an important factor for the success of enterprises. For this reason, it is important to ask yourself the best way to construct and manage the existing IT on-premise resources. To dig out some of the inherent more optimized schemes, it should be recognized that the existing on-premise scheme:
Investment in technical capacity is a risk: the need to calculate the capacity and capacity must be estimated in advance;
Some additional computing power is a waste of time, or worse, when it is not in time to provide services when needed;
Effective investment in computing power also requires a deep understanding of project requirements, as well as a deep understanding of the development trend of technology and the life cycle of the technology.
It is difficult to keep top of the IT's technical personnel: attracting and retaining skilled personnel is complex and expensive, and requires a large amount of effort, which also leads to an increasing cost per year. In keeping with the career path to maintain a consistent growth, the cost is difficult to predict, and is a never-ending management challenges. The change of the new technology may be inconsistent: the new technology of the cognitive, experimental and the use of the process is unstructured, passive and slow.
IT R & D expenses are usually not part of the IT management costs, the IT department is usually the supporting nature of the Department, and in the front of the business sector needs to be in the forefront of demand change, the business will directly promote the change of IT technology, business needs change will lead to a historical legacy system can not effectively support. At present, companies usually need to update the existing system, usually because of the cost of the problem, not because of the need for business development. Innovation in the business sector is often dragged down by complex and expensive IT changes.
For the value of the cloud to talk about a lot, the need to emphasize here is that the user to migrate to the cloud is not a black or white choice, cloud based IT management method is compatible with the existing IT on-premise management model. Find a suitable way to evaluate which approach will give you the best business value, and we can begin to understand the impact of the cloud on the existing business processes.

For many companies, the public cloud is the most typical enterprise cloud computing.

The traditional office product components requires every enterprise users have a license, needed to buy permits capital input will be as the enterprise capital expenditure of depreciation. However, if the business adjustment does not need so much user license, he couldn't find Microsoft refund.
Office365 services based on public cloud can make the user according to the actual amount per month to pay, for most companies, the investment will be treated as operating expenses rather than capital to look at. This approach can greatly reduce the cash flow pressure, rather than a sudden occurrence of a large number of capital spending on the purchase, and then continue to decline in three years and cost sharing.
Public cloud also exist. The most obvious is the most public cloud service based applications are not easy to be personalized, if you need to enhance the safety and regulatory compliance requirements, the public cloud services will make you hesitant, you may consider private cloud.
Private cloud
As the private cloud is dedicated to the company's internal services, whether it is operating or have third party partners to operate, can have more software features and business process customization freedom, specific functions and business processes are plastic. Upgrade and operation and maintenance can also be fully in accordance with the user's schedule, public cloud these are often difficult to achieve.
Private cloud can better protect assets. In many cases, users do not need any access to the system with a management level; you only need to have the ability to access and configure your application. Business safety and regulatory rules, such as compliance
