Azure Load Balancer
Save
Azure Load Balancer is a cloud-native load balancing service that provides high availability and performance for your applications. It can distribute traffic across multiple instances of your application, ensuring that your users always have access to your services. Load Balancer also provides a number of features to help you manage your traffic, such as:
Layer 4 Load Balancing
Layer 4 Load Balancing is a technique used to distribute traffic across multiple servers based on the IP address and port number of the incoming request. This is the most common type of load balancing and is used to improve the performance and availability of web applications, application servers, and other network services.
Layer 7 Load Balancing
Layer 7 Load Balancing is a more advanced technique that takes into account the content of the incoming request. This allows you to distribute traffic based on factors such as the URL, HTTP method, or even the user's location. Layer 7 Load Balancing is often used to improve the performance and availability of complex applications, such as those that require authentication or require access to sensitive data.
Health Probes
Load Balancer can be configured to use health probes to monitor the health of your application instances. If a health probe fails, Load Balancer will automatically remove the instance from the load balancing pool. This helps to ensure that your users are always directed to healthy instances of your application.
Auto Scaling
Load Balancer can be integrated with Azure Auto Scaling to automatically add or remove instances from the load balancing pool based on the demand for your application. This helps to ensure that your application is always running at the optimal level of performance.
