In the internet industry, architecture diagrams are an important tool used to visually display the architecture of software, systems, applications, etc., and the relationships between their components. Common types of architecture diagrams include: business architecture diagrams, application architecture diagrams, system architecture diagrams, technical architecture diagrams, deployment architecture diagrams, data architecture diagrams, product architecture diagrams, functional architecture diagrams, information architecture diagrams, etc.

Common elements in deployment architecture diagrams include: infrastructure layer elements, network and communication elements, application and service layer, users and customers, graphical symbols, and connection styles, etc.

Access Layer: Used to receive external requests, it is the "entrance" to the system.

Service Layer: Implements specific business logic, usually composed of multiple services or microservices.

Communication and Integration Layer: The interaction mechanism between modules or between the system and third parties.

Data Layer: Responsible for data persistence and management.

Operations and Monitoring Layer: Ensures system stability and observability.

Deployment and Infrastructure Layer: Deployment method and basic support of underlying resources.

Security Layer: Ensures access control and data security of each module in the system.

Deployment architecture diagrams can help developers better understand the overall structure of the system, as well as the data flow and interaction methods between components. In addition, through deployment architecture diagrams, developers can better plan system deployment and expansion strategies, improving the system's maintainability and scalability.

Development Collaboration: Clearly know the deployment location of each service and dependent components, avoiding deployment errors

Operations Deployment: Guide environment setup, version release, capacity assessment, health monitoring, etc.

Security Assessment: Review network isolation, authentication and authorization, port exposure, traffic control, etc.

Performance Planning: Analyze bottlenecks, make capacity forecasts, support elastic expansion plans

Disaster Recovery Design: Display master-slave structure, multi-active in different locations, automatic fault switching mechanism

Monolithic Deployment: All modules are deployed on the same or a few machines

Distributed Deployment: Modules are clearly divided, services are deployed on multiple nodes

Microservices Deployment: Based on containers or service mesh, each module is independently deployed and can scale independently

Hybrid Cloud Deployment: Some modules are deployed in local IDC, some are deployed in the cloud

Multi-active Deployment: Multiple nodes/regions provide services simultaneously, improving availability and disaster recovery capability
