Internet Features

On the one hand, SaaS services provide services to users through Internet browsers or WebServices/Web2.0 program connections. , making SaaS applications possess typical Internet technology characteristics; on the other hand, because SaaS greatly shortens the time and space distance between users and SaaS providers, the marketing and delivery of SaaS services are very different from traditional software. .

If you have access to the Internet and a browser, you can use ERP and CRM systems. Rapid implementation, convenient use, and low price all depend on the Internet characteristics of SaaS products.

Multi-tenancy features

SaaS services are usually based on a standard software system to provide services to hundreds or thousands of different customers (also called tenants). This requires SaaS services to support the isolation of data and configuration between different tenants, thereby ensuring the security and privacy of each tenant's data, as well as users' personalized needs for interfaces, business logic, data structures, etc. Since SaaS supports multiple tenants at the same time, and each tenant has many users, this poses great challenges to the performance, stability and scalability of the infrastructure platform supporting the software. SaaS is an Internet-based software delivery model. Optimizing the performance and operating costs of software after large-scale application is the core task of architects.

SaaS enables software to be used by customers in the form of services based on the Internet, so many service contracts are signed, service usage is measured, and online service quality is guaranteed and services Issues such as fee collection must be considered. These issues are usually not considered by traditional software.

Scalable features

Scalability means maximizing the concurrency of the system and using system resources more efficiently.
