"description" This article has made a simple review of the different advantages and disadvantages of the current cloud computing approach to enterprise business and it capabilities, and the overall article is not very deep at each point, just reference it.

Body

Although cloud computing is very hot, not all enterprises are migrating to the cloud, in fact, there are only a few enterprises and organizations to move their it to the cloud, there are many reasonable reasons for enterprises to prefer the self-owned on-premise model, after all, many companies want to have full control over their data.

From the big picture, it is hard for corporate CIOs and CTO to reject the hand that cloud computing has given them, and the benefits of the flexibility, cost and productivity of the IT capabilities built on cloud computing cannot be overlooked. Enterprises are faced with the choice, that is, there are more than one cloud model and cloud provider for users to choose, to make a reasonable choice, you should make any decision before making any decisions familiar with a number of key factors

For enterprise IT leaders, the challenges facing cloud computing are constant, such as:

1. Is it resource building and architecture of traditional on-premises a good way to protect corporate investment?

2. Does this approach help enterprises to rapidly capitalize on emerging tools and drive more effective methodologies and technological innovations?

3. How can we effectively control proprietary/strategic IT assets and discover ways to make our IT investments more effective as early as possible?

Find the best way to apply

continuous improvement of IT asset management strategy is an important factor of enterprise success, for this reason, you should constantly ask yourself whether your existing on-premise it resource building and management is the best way? to dig out some of the more inherently optimized alternatives, you should recognize the existing On-premise scenario:

1. Investing in technical capacity is risky: the required computational capacity and capacity must be estimated in advance.

2. When estimates are inconsistent with reality, some additional computational power is wasted, or worse, when needed, the service is not available in a timely manner.

3. Effective investment in computing capacity also requires a deep understanding of project needs, as well as the development trends of technology and the life cycle of technology.

It is difficult to retain top it talent: attracting and retaining skilled personnel is complex and expensive, and requires a lot of energy from management, and it also leads to an increasing annual cost. the cost of maintaining a consistent growth in personnel skills and career paths is unpredictable and a never-ending management challenge. The changes in new technologies may be inconsistent: the cognition of new technologies, experimental attempts, and the process of adoption are unstructured, passive and slow.

It research and development costs are usually not part of IT management costs, IT department is usually a supportive department, and the front line of the competition business units in the front of the demand change, often directly promote it technology change, business needs change will lead to legacy systems can not be effectively supported. At present, enterprises often need to update existing systems, usually because of cost issues, not because of business development needs. Business unit innovations are often dragged down by complex and costly it changes.

For the value of the cloud people talk a lot, it needs to be emphasized here is the user migration to the cloud is not a black and white choice, cloud-based IT management method can be compatible with the existing on-premise IT management model. Find an appropriate way to evaluate which approach will give you the best business value, and we can begin by understanding the impact of the cloud on existing business processes.

Public cloud

For many enterprises, public cloud is the most typical choice of enterprise cloud computing journey. The public cloud is appropriate for small businesses as well as for large businesses, such as Microsoft's Office 365 services, where the cost advantage is obvious. Traditional Office product components require a license for each enterprise user, and the investment required to purchase a license is depreciated as a corporate capital expense. However, if the business adjustment does not require so many user licenses, he will not be able to find Microsoft refund.

OFFICE365 services based on the public cloud allow users to pay for the actual monthly usage, and for most businesses this investment is treated as operating expenses rather than capital expenditure. This can greatly reduce the pressure on cash flow, rather than the sudden occurrence of a large amount of capital expenditure, and then the depreciation and cost-sharing within three years.

The problem with public cloud is also present, most notably, most applications based on public cloud services are not easily personalized, and if you need to enhance security and compliance requirements, for example, or need better control or customization in your environment, public cloud services can make you timid, and you might want to consider a private cloud.

Private Cloud

Since the private cloud is dedicated to the internal services of the company, whether it is operating on its own or with a third-party partner, you have the freedom to customize more software features and business processes, with specific features and business processes that are malleable to meet your business needs. Upgrades and operations can be fully based on your schedule, and public clouds are often difficult to achieve.

A private cloud can also protect your assets better. In many cases, there is no need to have any administrative level of access to the system; You only need the ability to access and configure the application you are using. Corporate Security and regulatory rules, such as compliance with Dodd-frank or hipa A, a private cloud is a better choice if you need clear control and high security measures.

On the other hand, private clouds are often a more expensive option than public clouds.

IaaS vs Cloud

Many companies do not want to establish and maintain a data center, so they can use the infrastructure as a service (IaaS) cloud. Building a data center is a very large capital outlay, especially for a data center that needs to withstand inclement weather and has a number of redundant power to respond to changing computing power requirements. Once it is built, the data center is physically protected, which of course requires 24/7 of people to carry out the operations.

In addition to all this, you need to figure out how many physical servers and virtual servers you have to run your business and the processing power you need. In addition, there is a need for some kind of storage, possibly a storage area network (SAN), for maintaining important data and files. You have to figure out how much storage you need now and in the future, and you will want to get the planning in this area to be correct and effective, because SAN storage is very expensive.

IaaS Services let you no longer need to deal with these details, but can meet your flexible needs, expansion (or contraction) is very easy to achieve, only when you need additional resources to pay for it. IaaS services also allow varying degrees of flexible control.

An enterprise may want its IAAS provider to replace its server room, but let the enterprise's own employees manage the business site. Other businesses may abandon more management responsibilities, reduce IT infrastructure personnel, or redeploy the IT workers to places where they need them more.

Hybrid Cloud

Some businesses can benefit from the use of multiple cloud methods. You may have a private cloud deployed on-premises that runs a highly proprietary business application, but you can also use Office 365 and financial management apps on public clouds.

Your IT management team or technical advisor can help you evaluate the technologies you are using, build a business case, deploy applications on different clouds, and achieve optimal resource allocation. Configuring a private cloud or a shared cloud is primarily based on security and control requirements, as well as an assessment of the skills and competencies of your IT team. If you have a small IT team, you may not be able to manage large data centers or complex financial applications in a private cloud environment. A senior IT consultant can guide you through more long-term planning for resource allocation choices.

While the hybrid environment can be complex, users don't have to worry about it because all the complexities are behind the scenes. With a single sign-on approach, a hybrid environment allows users to feel like maintaining and using a fully owned system.

The business needs are first-level

Usually the drive of the business will lead to the enterprise to the IT and other support platform upgrade, for the choice of cloud platform, generally have the following three kinds of business requirements driven:

1. Companies prefer operating expenses to reducing capital expenditures-as mentioned earlier, the transition to a model of operating expenditure will provide more cash to the business and provide more financial flexibility in terms of operations.

2. Compliance concerns-that is, compliance requirements must be met to avoid unnecessary expenses, audits and headaches in the business. All of these dilemmas can be helped by private cloud providers, easing the cost of security and compliance controls.

3. IT staff and competency-enterprises need to run secure and reliable IT capabilities to support the business. The technical capabilities required for the current IT environment have become so diverse and complex that it is difficult for any individual to do so. People are becoming more and more expensive, and it's hard to find the right people and let them stay.

Despite the rapid advances in technology, the capabilities of cloud computing are not much different. The depth of solution that has been listed in a variety of cloud computing solutions (through virtualization), his inherent flexibility, will help meet your business needs. You can help you develop a comprehensive cloud computing solution to meet your business objectives and optimize your technical competency planning in the foreseeable future, outlining your ability to spend on monthly business operations (not capital) through an IT management team or security technology consultant.
