What is the server cluster architecture of a super-large shopping website? It is better to have an architecture diagram

A server cluster refers to the centralization of many servers to perform the same service. In the eyes of the client, it is like there is only one server.

The processing of thumbnails, I think some websites are directly generated when uploading pictures, and some are processed in httpmodel and generated when accessing. The advantage of directly generating thumbnails is to save performance. Httpmodel, on the contrary, a new picture will be generated every time you browse the picture. The server is under great pressure, so it is recommended to generate it directly.

SOA architecture is a service-oriented architectural idea. In essence, it is service-centered, splitting applications into multiple services, extracting reusable services, and improving the convenience of individual expansion and development of each service.

Server specificity is obvious. At present, general servers will transform into dedicated servers. Take email services as an example. In the past, you only needed to install a set of email software on any service to provide email services, regardless of its stability and ability to process emails. As long as it can be used.

ü Large-scale portals and e-commerce websites need LVS. 2 LVS Introduction LVS is an abbreviation of Linux Virtual Server, which means LinUx virtual server is a virtual server cluster system that can realize the load balancing cluster function under the UNIX/LINUX platform.

Which components of the cloud infrastructure help to automatically create and deliver computing resources to users

1. Cloud: allocate and combine the resource pool, according to the application system The unified needs to automatically generate and expand the required hardware resources, and improve IT efficiency through processization, automated deployment and management of more application systems.

2. Computing resources: This is the core part of the cloud infrastructure, including computing instances such as virtual machines and containers. They provide users with the computing power they need to support the operation of various industrial Internet applications. Storage resources: Cloud storage services provide users with data storage and management functions.

3. Infrastructure Management: Cloud computing infrastructure management services help users manage underlying hardware resources, such as servers, networks and storage devices. These services usually include automated tools and technologies, such as resource monitoring, capacity planning and troubleshooting.

4. The architecture of cloud computing includes: application layer, platform layer, infrastructure layer and data center layer.Application layer: The application layer is the top-level cloud computing service layer, which includes application services in various fields. The services of this layer are user-oriented and usually provided through the web interface or API.

5. IaaS resources can also be automatically stretched or contracted according to workload or task requirements.
