With the development of the Internet, the scale of website application is expanding, the conventional vertical application architecture cannot be solved, the distributed service architecture and the mobile computing architecture are imperative, and a governance system is urgently needed to ensure an orderly evolution of the architecture.
- Single Application Architecture
- When site traffic is small, you need only one app to deploy all the features together to reduce deployment nodes and costs.
- At this point, the data Access Framework (ORM) is the key to simplifying the effort of adding and deleting changes.
- Vertical Application Architecture
- As traffic increases, a single application increases the acceleration of the machine, and the application is split into several unrelated applications to improve efficiency.
- At this point, the Web Framework (MVC) used to accelerate the development of front-end pages is critical.
- Distributed Service Architecture
- When the vertical application is more and more, the interaction between applications inevitably, the core business extracted, as a separate service, gradually formed a stable service center, so that the front-end application can be more rapid response to changing market demand.
- At this point, the Distributed Service Framework (RPC) that is used to improve business reuse and consolidation is critical.
- Flow Computing Architecture
- When the service is more and more, the evaluation of capacity, and the waste of small service resources appear gradually, it is necessary to add a dispatch center to manage cluster capacity and improve cluster utilization based on access pressure.
- At this point, the resource Scheduling and Governance Center (SOA) that is used to improve machine utilization is critical.
The evolution of Web system architecture is very image
