jewelry wholesale platform The API gateway provides a single unified API entrance point across one or more internal APIs. Generally, it also includes the characteristics of restricting access rate restrictions and related security. The API management of Tyk.io adds additional functions, such as analysis, monetization and life cycle management.
The micro -service -based architecture may have 10 to 100 services. The API gateway can provide a unified entry point for external consumers, and it has nothing to do with the number of internal microservices.
api gateway for microservices:
1. Prevent internal attention to exposure to external clients
api gateway to separate external public API from internal microservices API, allowing the addition of microservices and changing boundaries. As a result, it can reconstruct and appropriate sizes without the negative impact of the external binding client. It also provides a single entry point for all your microservices, hiding service discovery and version control detailed information on the client. 2. Add an additional security layer to your microservices
API gateway to prevent malicious attacks by providing an additional protective layer, such as SQL injection, XML parser vulnerability and rejection service (DOS) attack.
3. Support hybrid communication protocol
Although the external API usually provides an API based on HTTP or REST, internal microservices can benefit from different communication protocols. The protocol may include Protobuf or AMQP, or integrates SOAP, JSON-RPC or XML-RPC systems. The API gateway can provide external, a unified REST API on top of these different protocols, allowing teams to choose APIs that are most suitable for internal architecture. 4. Reduce the complexity of microservices
If the microservices have common attention points, such as using the authorization of API token, access control implementation and rate restrictions. Each of these attention can be achieved by requesting each service, but this adds more time costs to the development of microservices. The API gateway will delete these issues from your code, allowing your microservices to follow the task at hand. 5. Micro -service simulation and virtualization
In the separation of microservices API from external APIs, you can simulate or virtualized services to verify the design requirements or assist integrated testing.
api gateway service objects
api gateway can provide API access for the web and APPs, or you can provide API interfaces for IoT devices. In addition, companies dedicated to the development of ecology will also provide API gateways for some partners for their calling universal microservices. For companies that can provide data or algorithms, they can register their own APIs in the API network of the cloud market to provide services outside.
