Difference between an API Gateway and a Load Balancer
API Gateway:
API Gateway, a serverless management tool, functions as an intermediary between microservices and users. By establishing APIs in your client application, you can make them accessible to outside programmers as well. Supporting HTTP, WebSocket, and REST APIs, API Gateway serves as an exclusive server that can personalize every client.
Here are some of the advantages of using API Gateway:
- Improved performance: By enabling the system to handle a greater quantity of requests and respond faster to clients, the API gateway can assist in enhancing general performance. This is due to its capacity to handle responsibilities like routing and load balancing.
- Simplified system design: The clients have an easier time accessing the microservices, and the overall system design is simplified thanks to the API gateway’s provision of a solitary entry point.
- Enhanced security: Using the API gateway allows for intensified security measures, as it can enforce access control and authentication policies to deter unwanted access and safeguard the system.
- Improved scalability: The API gateway can distribute incoming requests among multiple instances of a microservice, enabling the system to scale more easily and handle a larger number of requests.
- Better monitoring and visibility: The system can more easily handle an increased amount of requests with the assistance of the API gateway’s ability to distribute incoming requests among a variety of microservice instances, resulting in superior scalability.
Load Balancer:
To make sure that performance stays top-notch and to avoid server crashes, a load balancer plays a key role in the layout of any system. It distributes incoming requests among multiple servers so that no single server gets swamped with traffic. It’s a vital component.
Here are some of the advantages of using API Gateway:
- Big Data: Businesses can make informed decisions based on the examination of worldwide user-provided big data, which offers actionable insights.
- Improve Efficiency: In order to provide clients with a better experience, servers need to run smoothly and provide swift responses. Load balancers are the key to achieving this by reducing the pressure on servers.
- Predictive Analysis: Load balancer software can use predictive analysis to anticipate traffic bottlenecks before they materialize in reality.
- Resilience: Prompt component replacement makes downtime practically non-existent, while simultaneously providing valuable insight into equipment rehab needs.
- Security: Your website and applications can attain added security with Load Balancer, all without any changes. This extra layer of security helps to safeguard your digital assets.
- Scalability: Services don’t need to be impacted if you modify the server infrastructure due to the ability of Load Balancers to provide scalability.
Difference between an API Gateway and a Load Balancer:
| Feature | API Gateway | Load Balancer |
| Function | Acts as an intermediary between clients and microservices, enabling developers to create, manage, and secure APIs | Distributes traffic across multiple servers to ensure availability and prevent overloading |
| Traffic Management | Controls traffic to microservices | Distributes traffic across multiple servers |
| Protocol Support | Supports multiple protocols such as HTTP, WebSocket, and RESTful APIs | Supports HTTP, TCP, and UDP protocols |
| Security | Provides various security features such as authentication, authorization, and encryption | Supports SSL/TLS encryption |
| Monitoring | Provides in-depth insights into API usage, latency, and error rates | Provides basic monitoring of server health |
| Scalability | Can horizontally scale to handle increasing traffic | Can horizontally scale to handle increasing traffic |
| Deployment | Deployed as a separate service or hosted solution | Deployed on-premise or as a cloud service cost typically |
| Cost | Typically more expensive than a load balancer | Typically less expensive than an API gateway |
