Public cloud or private cloud enterprise how to penetrate real demand

For the average enterprise, the ultimate need is to be able to help and promote the application of the service, not the underlying IT infrastructure. But IT infrastructure is the foundation of these applications, so enterprises need IT infrastructure as the underlying platform, and the corresponding application. In the traditional way, for applications, enterprises can choose the market software packages, such as many enterprises using the market ERP and CRM software packages. In addition, if the requirements of the enterprise are relatively special, or for other reasons, the enterprise can choose to develop its own application. For the application of the operating environment, enterprises can choose to build their own data center to operate the dimension, you can choose a Third-party hosting platform or cloud computing platform to run the application.

The cloud computing platform is an extension and development of the traditional hosting platform, providing a higher level of service automation than the managed platform. In fact, we can use these applications and services as a way to achieve different levels of outsourcing. Whether the application or the bottom of the platform, we can build and use the third party services two dimensions to explore, from two dimensions of the application of the construction and operation of the way.

How companies penetrate real cloud requirements

Obviously, the stronger the enterprise's ability to control the application, the closer to the upper right corner, the better the scale effect. Enterprise is to choose their own construction and operation of IT services, or directly using a third-party public cloud services, which are engaged in the industry, enterprise size and application types and many other factors.

Here are four different ways to discuss this.

1. Location of IT facilities

When the enterprise builds a private cloud platform itself, IT infrastructure is its own, usually within the enterprise. When using the public cloud platform, IT infrastructure is located in a third party data center. The exception here is that there is now a concept of a virtual private cloud (VPC, Private Cloud) proposed by a service provider that refers to a dedicated computing environment that is isolated by technology within a Third-party data center and connected to the enterprise through a secure channel.

2. Infrastructure differential

For many large enterprises, their IT infrastructure has often adopted different technologies and platforms due to years of it construction and technology evolution, which means that these enterprises are using heterogeneous platform environments. However, for most of the current public cloud service providers, their platforms are often built on inexpensive and standard hardware platforms. These standardized ways to build a platform to better cost-effective to meet the needs of most users. In addition, in the provision of services, public cloud service providers often provide the most popular, the most extensive and centralized services. Therefore, for the public cloud services, its services and environment are often homogeneous, which is not the same as the enterprise's own IT environment.

3. Business model

If companies choose to build their own IT systems, it is clear that a large amount of one-time investment is needed to buy software, hardware, and even the infrastructure of the data center. In the corporate financial statements, this is reflected in a relatively large fixed cost. However, if the enterprise adopts the public cloud service provided by the third party, then according to the current charging method of cloud computing services, the enterprise can choose the monthly service fee or the amount of it resource usage to pay. In this way, the enterprise does not need a large amount of upfront investment can use IT services, it is reflected as a continuous operating costs.

4. Different levels of control

The enterprise itself constructs the IT system is as the enterprise assets completely by the enterprise own, and by the enterprise own to carry on the dimension. Although the enterprise needs its own IT operational team, the advantage is that the enterprise can independently control IT systems, and according to the actual needs of the transformation and customer. And for the public cloud services, the enterprise is actually using the rental services, the advantage is that they do not need to manage the basic platform services, but for enterprises this also reduces its ability to customize, because all the infrastructure, including servers, networks and storage, and the software platform above is maintained and managed by a service provider.
