How to build the optimal cloud computing platform infrastructure

First of all, because cloud computing platforms tend to run more than one or even a single type of application, it is essential to choose the appropriate device. For example, when running internet-based or small value-added applications, an open x86 server architecture is usually a good fit, but if you need to run some complex applications, such as databases, online processing applications, the stability and security requirements are often higher, Using UNIX servers in this case is a more appropriate option. Following this principle will help the cloud computing platform to optimize computing power and computing resources. From a storage product perspective, choosing a fibre based SAN storage approach is a good choice for complex applications, but SCSI is more adaptable for applications that are relatively independent and less complex. Therefore, applicability is the primary principle for building a successful cloud computing platform.

Secondly, openness is an important feature of cloud computing platform distinguishing from traditional data center, that is, it is open to application. For example, in the cloud computing platform running, there may be different types of applications, service access, although in the interface types and other aspects have specific standards to standardize, but the use of relatively mainstream, open hardware architecture, operating system, for the new application of seamless access is particularly necessary.

In terms of compatibility, the hardware system and the business system should be considered from two aspects. The compatibility of hardware system is shown in the aspects of server interface, chip type, storage interface and architecture. For example, because cloud computing typically uses virtualization to achieve dynamic management and improve server and storage utilization, the CPU's support for virtualization technology is different, and you need to choose servers and CPUs that are better compatible with mainstream virtualization software to support virtualized deployments. Similarly, in network devices, if you want to implement the free migration of virtual machines across the network segment, routers also need to be able to have a good support for this function and compatibility. At the same time, cloud computing platform should be compatible with existing business systems, in the system migration to the original system does not need to make major changes to achieve smooth migration, so as to ensure the continuity of key business and system migration costs.

Increasingly scarce space has become a common dilemma for data centers, and when choosing the hardware of a cloud computing platform, it is also necessary to consider the layout of the environment and space. Traditional servers require a lot of racks, space, and a lot of cable and auxiliary materials. In addition, space occupancy will also bring management difficulties, increase maintenance costs. In order to create an efficient cloud computing platform, it is necessary to consider increasing the density of the deployment when the hardware is built, and using high-density computing system is a good solution.

Green is the eternal topic of the data center, for the cloud computing platform, the implementation of green it is an important building principle. Poor platforms will consume more servers, storage, and network equipment, increasing the number of cooling air conditioners and consuming large amounts of electricity. In fact, these electrical energy consumption for the cloud computing platform, is completely through the optimization design to avoid. In addition to choosing hardware products with lower energy consumption, reasonable planning and management are also needed in power supply system, air duct, wind way, hardware pattern and operation management.

In summary, with the rapid development of large-scale cloud computing data center, the late expansion and maintenance of the difficulty and daily surge, in the design of cloud computing platform architecture, fully consider applicable, open, compatible, high-density, green features has become a consensus.
