Security: Cloud computing services take security precautions to avoid the ability to put the system in a potentially dangerous or unstable state. Relative security has long been a controversial topic for cloud computing services, and could hinder the development of cloud computing if not handled properly. There is a view that the internal management of user data is more secure, and there is another point of view that the cloud provider can provide higher security. The Cloud Security Alliance (CSA) is a non-profit organization that is set up to improve the security of cloud computing and promote cloud computing towards practice. &HTTP://WWW.A ...

Service level agreement: English abbreviation SLA refers to a mutually approved contract between the service provider and the user based on a certain fee, which defines the type of service, quality of service, customer payment, default penalty, Amendment clause, and obligations of both parties to ensure service performance and reliability.

soa:service-oriented architecture, service-oriented architecture, English abbreviation SOA, is a component model that links the different functional units of an application, called services, through well-defined interfaces and contracts between these services. Interfaces are defined in a neutral way, independent of the hardware platform, operating system, and programming language that implements the service, which enables services built in such systems to interact in a common way.

Loose coupling: Loosely coupled usually refers to the message based architecture, where the client and the remote service do not know how the other is implemented, and the communication between the client and the service is governed by the schema of the message. As long as the message conforms to the negotiated schema, the implementation of the client or service can be changed as needed without fear of damaging the other. Loosely coupled communication mechanisms provide many of the advantages that tight coupling mechanisms do not have, helping to reduce dependencies between client and remote services.

Tight coupling: A closer system architecture between client and service, a close relationship between modules or systems, the existence of mutual invocation, and high resource sharing characteristics. Tight coupling can often provide performance benefits that facilitate tighter integration between clients and services, which may be required in the presence of security and transaction processing requirements. The disadvantage of tight coupling system is that the result of updating one module will cause other modules to change, and it is difficult to reuse specific correlation module.
