Traditional cloud description

Before cloud computing matures, we should pay more attention to the details of the system cloud computing architecture, which has achieved many changes from the traditional architecture to big data on the cloud. Traditional big data platform computing and data are generally together. After computing on the cloud, it may be a virtual machine or a container, and storage and computing are separated. When any computing node accesses the storage, it migrates the data to the local area through the high-speed Internet. The advantages achieved are the service and flexible configuration of big data. Therefore, with the powerful computing performance and advantages of cloud computing platform, the transformation from traditional big data platform to data on the cloud will provide users with higher flexibility and manageability, and save users a lot of costs.

Traditional it architecture

The construction of traditional IT environment is a complicated process. From installing hardware, configuring network, installing software, applications, configuring storage, etc. Many links need a certain technical force reserve. When the environment changes, the whole process needs to be repeated. As we all know, the installation environment of different people will be very different. Considering it in a complex enterprise environment, even if it is explained, it still cannot guarantee the consistency of the environment.

Cloud architecture

As we all know, traditional servers include processor, storage, network, power supply, fan and other module devices. Compared with traditional servers, cloud servers focus on high-performance throughput computing power and total workload in a certain period of time. Therefore, the cloud server is very different from the traditional server in architecture.

Generally speaking, the construction of enterprise cloud architecture mainly comes from six aspects: hybrid cloud construction, enterprise-level cloud services, compliance, security, innovation and business continuity. The following are three classic architectures on Alibaba Cloud for reference:

I. Network infrastructure on the cloud

Customized private networks: subnetting and routing planning.

Network logical isolation: network virtualization, complete isolation between VPCs.

Public network access: flexible IP access, SNAT/DNAT gateway.

Construction of hybrid cloud: physical private line /VPN gateway realizes the interconnection between cloud and data center.

Access control: security groups realize network isolation of different security domains.

Second, the security infrastructure on the cloud.

DDos protection

WEB application protection

Authorization and access control

Audit log threat detection system

Security assessment and hosting services

Third, the disaster tolerance architecture in different places in the same city on the cloud

High availability in the same city: automatic switching, disaster tolerance in the same city, no extra cost.

Disaster tolerance in different places: multi-geographical distribution, application and data-level disaster tolerance

superiority

Cloud server architecture includes cloud processor module, network processing module, storage processing module and system module. The advantages of this architecture make the cloud server greatly improve the utilization rate. Using multiple cloud processors to complete the system design, and introducing a low-power management scheme to complete the centralized redundant management of the system, while optimizing the system design and removing redundant hardware. Through efficient resource integration, the utilization rate is improved, thus improving the cost performance and reducing the rental price of the website server.

Cloud server has saved a lot of business costs for all kinds of enterprises with its reasonable website server rental price, thus winning the favor of many enterprises.
