Soa is a service-oriented architecture. It is a component model. Different components are linked by well-defined interfaces. It is like building a house, a brick, a brick, and a tile. The idea of the SOA architecture advocates that we should not do anything with bricks and tiles. One wall, one roof, one beam, and so on are all well done by others. We can build the house by ourselves, you need to change the requirements of each house. You need to open a window on the wall and build a chimney on the roof as needed. You need to build bricks on your own. The advantage is that the development efficiency is high, the system is stable, and the implementation and maintenance are convenient. both development and maintenance costs are low.

The Enterprise Service Bus (ESB) is a distributed, message-based integrated solution that complies with open standards. The role of an ESB is to establish reliable communication between various IT resources, such as application systems, platforms, and services distributed on different systems in an enterprise. When the IT department is paying more and more attention to building SOA to reduce development costs and improve business agility, ESB becomes the key first step in establishing Enterprise SOA.
