What Is A Service Proxy? Everything That You Need To Know About It

A client-side proxy for microservices applications that lets application components transmit and receive traffic. So, What Is A Service Proxy?

A service proxy’s primary responsibility is to guarantee that traffic is directed to the correct target service or container and to enforce security requirements. Service proxies can aid in ensuring that application performance requirements are satisfied.

What is a Service Proxy?

A service proxy is a network component that functions as a go-between for requests for resources from microservices application components.

A client connects to the service proxy in order to request a certain service (file, connection, web page, or other resources) from one of the microservices components.

Based on the load balancing mechanism that has been established, the service proxy examines the request and routes it properly.

What is a Web Service Proxy?

A web service proxy acts as a middleman between the calling application and the destination web service. Within the request chain, the proxy might add new behaviors. Then, a Web Service proxy can:

• Change the HTTP headers.
• Perform URL filtering and content switching
• Provide content caching
• Support Blue-Green deployments and Canary testing

How does a Service Proxy Work?

A service proxy acts as a middleman between the client and the server. There is no direct contact between the client and the server in a service proxy arrangement.

Service proxies are often maintained and coordinated from a central location. They do this by connecting to the proxy and sending requests for resources (document, web page, or file) hosted on a distant service.

The proxy handles this request by retrieving the necessary assets from a distant service and sending them to the client.

What are the advantages of Service Proxy?

Service proxies provide several advantages:

1) Granularity: For microservices applications, the service proxy is an essential component of the networking architecture. It provides the application service granularity required to develop scalable microservices applications.

2) Traffic management: Service proxies may provide applications inside and across data centres with both local and global load balancing services.

3) Service Discovery: With the proper design, service proxies may enable service discovery by mapping service host/domain names to the appropriate virtual IP addresses from which they can be accessed.

4) Monitoring and Analytics: Service proxies may give telemetry to aid in application performance monitoring and alerting on any application faults or abnormalities.

5) Security: Service proxies may enforce L4-L7 security rules, application rate limitation, web application firewalling, URL filtering, and other security services such as micro-segmentation.
