Service-oriented architecture
In the previous section, we discussed the monolithic architecture and its limitations. We also discussed why it does not fit into our enterprise application requirements. To overcome these issues, we should go with some modular approach where we can separate the components such that they should come out of the self-contained or single .NET assembly.
The main difference between SOA & monolithic is not one or multiple assembly. But as the service in SOA runs as separate process, SOA scales better compared to monolithic.
Let's discuss the modular architecture, that is, SOA. This is a famous architectural style using which the enterprise applications are designed with a collection of services as its base. These services may be RESTful or ASMX Web services. To understand SOA in more detail, let's discuss service first.
