Large-scale website Architecture Evolution (8) Business splitting and Architecture Evolution

In order to cope with increasingly complex business needs, large websites divide their businesses into different product lines and assign them to different development teams. This facilitates application expansion and maintenance. At the same time, different applications correspond to different databases, which reduces the pressure on all original business data in one database.

After a website is split into multiple different applications, each application is deployed and maintained independently. Communication between systems is generally completed using message queue middleware. Therefore, the updated architecture is as follows:

Conclusion: Business splitting not only solves the problem that a single application is too large, but also solves the problem that all business data is stored in the same database. Each application interacts with each other through message queues, this architecture is still quite common.
