How to analyze the six architectures of cloud computing? in view of this problem, this article introduces the corresponding analysis and solutions in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Cloud computing requires infrastructure to have good resilience, scalability, automation, data mobility, multi-tenancy, space efficiency and support for virtualization. So what should the architecture of each part of the data center infrastructure in a cloud computing environment look like?

1. Overall architecture of cloud computing data center

Cloud computing architecture is divided into two parts: service and management. In terms of services, it mainly provides cloud-based services for users, including three levels: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). In terms of management, mainly cloud management, its function is to ensure that the entire cloud computing center can operate safely and stably, and can be managed effectively.

2. Architecture of cloud computer room

In order to meet the needs of flexibility of cloud computing services, the cloud computer room adopts a standardized and modular computer room design architecture. Modular computer room includes container modular computer room and building modular computer room.

The application of the container modular computer room in the outdoor computer room scene reduces the pressure on the constructor in selecting the location of the computer room, and helps the constructor to shorten the original half-year construction period to two months, while the energy consumption is only 50% of that of the traditional computer room. it can adapt to the extremely harsh environment in hot and arid desert areas and polar cold regions. The building modular computer room adopts leading refrigeration technologies such as hot and cold air duct isolation, accurate air supply and outdoor cold source, which is suitable for the building construction and expansion of large and medium-sized data centers.

3. Cloud computing network system architecture

The overall structure planning of the network system should adhere to the design concept of regionalization, hierarchy and modularization, so as to make the network level clearer and the function more clear. The data center network is divided into areas according to the nature of the business or the role of network equipment, and can be planned from the following aspects.

The main contents are as follows: 1) according to the nature of data transmission service and user-oriented, the network system can be divided into internal core network, remote service network, public service network and other areas.

2) according to the different functions of the equipment in the network structure, the network system can be divided into core layer, aggregation layer and access layer.

3) considering the independence of the data application service of the network service, the mutual visit relationship of each service and the security isolation requirement of the service, the network system can be logically divided into storage area, application business area, front area, system management area, escrow area, external network access area, internal network access area and so on.

In addition, there is a network architecture for Fabric. After the deployment of cloud computing in the data center, the traditional network structure may make the network delay problem become a major bottleneck, which makes the need for low-latency inter-server communication and higher two-way bandwidth become more urgent. This requires the development of a flattened network architecture, and the ultimate goal is to minimize the number of network architectures between any two points.

One of the keys of Fabric network structure is to eliminate the concept of network hierarchy. Fabric network architecture can use array technology to flatten the network, compress the traditional three-layer structure into two layers, and finally transform it into one layer, and eliminate complexity and network delay by realizing the connection between arbitrary points. However, at present, there is no unified standard for the new technology of Fabric, and its promotion and application still needs more practice.

4. Cloud computing host system architecture

The core of cloud computing is the concentration of computing power and large-scale breakthrough. The type of computing provided by the cloud computing center determines the hardware infrastructure of the cloud computing center. From the point of view of the needs of cloud customers, cloud computing centers usually need to provide the following types of computing power on a large scale, and their server systems can adopt three (multi)-tier architectures. One is high-performance, stable and reliable high-end computing, which mainly deals with tightly coupled computing tasks. This kind of computing includes not only external databases, business intelligence data mining and other key services, but also its own accounts, billing and other core systems. Usually provided by large enterprise-class servers The second is general-purpose computing for many common applications, which is used to provide low-cost computing solutions. This kind of computing requires less hardware and generally uses high-density, low-cost, ultra-dense integrated servers to effectively reduce the operating costs of the data center and the use costs of end users. Third, for scientific computing, bioengineering and other services, to provide 100 trillion, trillions of computing capacity of high-performance computing, its hardware basis is high-performance clusters.

5. Cloud computing storage system architecture

Cloud computing adopts the mode of unified and centralized storage of data. in the cloud computing platform, how to place the data is a very important problem. In the process of practical use, it is necessary to distribute the data to multiple disks of multiple nodes. At present, there are two ways to achieve the trend of storage technology, one is to use a cluster file system similar to GoogleFileSystem, and the other is the storage area network SAN system based on block devices.

GFS is a distributed file system designed and implemented by Google. It is based on a large number of ordinary PC installed with Linux operating system. The whole cluster system is composed of a Master and several ChunkServer. There are a variety of options for SAN connections. One option is to use optical fiber network, which can operate fast optical disk, which is suitable for places with high performance and reliability requirements. Another option is to use Ethernet and iSCSI protocol, which can run in an ordinary LAN environment and reduce costs. Using the SAN structure, a large amount of data transmission from the server to the shared storage device is carried out through the SAN network, and the local area network only undertakes the communication task between the servers. This division of labor makes more effective use of storage devices, servers and local area network resources, and makes the storage system faster, scalable and reliable.

6. Architecture of cloud computing application platform

The cloud computing application platform adopts the service-oriented architecture SOA, and the application platform provides the necessary infrastructure resources for deploying and running the application system, so the application developers do not need to care about the underlying hardware and application infrastructure of the application, and can dynamically expand the resources needed by the application system according to the application requirements.
