1. What is a software architecture? What is our current software development architecture based on? 2. What are the resource classifications?

1. There are many kinds of software architectures, and different architectures are suitable for different types of applications. The following are some common software architectures:

Single building:

Monomer architecture is to build the whole application into a single, tightly coupled unit. All functional modules are centralized and usually managed by a single code base. The advantages of this architecture are easy to understand, but it may be difficult to maintain and expand in large and complex applications.

Microservice architecture:

Micro-service architecture is a way to split applications into small autonomous services. Each service runs in an independent process and works together through a lightweight communication mechanism. The advantages of this architecture are scalability, flexibility and independent deployment.

Client-server architecture:

The client-server architecture divides the application into two parts: the client and the server. The client requests the server to obtain data or perform operations through the network. This pattern is usually used in distributed systems.

Hierarchical architecture:

The layered architecture divides the application into several layers, and each layer has a specific function. The common layer includes presentation layer, business logic layer and data access layer. This architecture is helpful for maintenance and reuse.

At present, the software development architecture is usually selected according to the specific project requirements. Micro-service architecture is very popular at present, because it helps to build flexible and extensible application systems.

2. Resource classification mainly includes the following aspects:

Hardware resources:

Include computers, servers, storage devices, network devices, etc.

Software resources:

Including operating system, database management system, application program, etc.

Human resources:

Including project team members, developers, testers, project managers, etc.

Time resources:

Time resource refers to the time required to complete the project, including planned time and actual execution time.

Financial resources:

Including project budget, capital investment, cost, etc.

The effective management of these resources is very important for the successful implementation of the project.
