CamelCamelCamel API Design Decisions

This lesson will discuss design decisions paramount to creating an effective C3 service. Mainly, we’ll decide on a suitable architectural style, data format, and HTTP version for an effective C3 service.

Design overview

Let’s start by understanding the architecture and workflow of the C3 service before diving into a discussion of design decisions because C3’s design architecture and workflow will enable us to make suitable decisions. Notice the synchronous communication of the C3 service with Amazon, a distinct service provider. The C3 API uses search, pub-sub, and product services. These services interact with Amazon’s services to provide data to potential customers. The following illustration demonstrates a high-level architecture of the workings of a C3 service:

The following table gives an overview of each of the components involved in a C3 service:

Workflow of C3

The C3 service works synchronously with the Amazon service. Let’s discuss the workflow of each service according to the functional requirements. Requests to C3’s API gateway can interact with any of the subservices of C3 according to the required functionality, as described below:

• Search product: If it's a search query from a user, the API gateway sends it to the search service of the C3. The C3’s search service ...
