The API gateways ensure API security by routing all the requests coming from the client side to back-end microservices. This layer keeps a check on unauthorized API requests and set ground rules on how to handle the API requests.
Securing Your Business Online Using API Gateways
We build systems in the Microservice architecture which involves the use of API Gateways. They ensure API security by routing all the requests coming from the client side to back-end microservices. This layer keeps a check on unauthorized API requests and set ground rules on how to handle the API requests.
Other Reasons to Use API Gateways
1. Easy Monitoring
You can monitor every single stat related to the APIs from the API dashboard like API calls, data latency, error rates, etc. This way you can take appropriate actions on time if anything wrong happens.
2. Better Performance
With the help of data caching and memory management mechanisms, API gateways ensure that the API requests are processed faster, the backend operations can withstand sudden traffic spikes, and hence the API performance becomes a lot better.
3. Flexible Security Controls
API Gateway eliminates the concerns of the security breach by verifying each API request before sending it to microservices and setting specific rules for how the API requests must be handled.
4. Lesser Microservice Complexity
API gateway reduces common concerns like authorization using API tokens, access control enforcement, and rate limiting from the code and ensures that microservices only focus on the task at hand.
5. Communication on Different Protocols
A microservice can use various types of protocols for communication like Transmission control protocol (TCP), User Datagram Protocol (UDP), Remote Method Invocation (RMI), and Simple Object Access Protocol (SOAP). While on the client side, it’s HTTP only. An API gateway ensures there’s smooth communication between these protocols.
6. Efficient Workflow Management
API Gateways ensure that there’s an active connection between clients along with handling message transfer and pushing data through back-end servers. It saves you from the hassle of managing servers or worrying about connected users and devices.
