Types Of Load Balancers In AZURE
Microsoft Azure offers several load-balancing services that can help distribute traffic across multiple servers or resources, ensuring high availability and performance. Here are some of the load balancing services available in Azure and how to choose the right one:
Azure Load Balancer: This is a basic load-balancing service that distributes traffic across multiple virtual machines (VMs) or instances of an application. It can be used for TCP/UDP traffic and provides health probes to ensure that traffic is directed only to healthy instances. This is a good choice for simple scenarios where basic load balancing is sufficient.
Azure Application Gateway: This is a layer 7 load balancer that is designed for web applications. It provides features such as SSL offloading, URL-based routing, and session affinity. It can also perform application-level health checks to ensure that traffic is directed only to healthy instances. This is a good choice for web applications that require advanced load-balancing features.
Azure Traffic Manager: This is a DNS-based load balancer that can distribute traffic across multiple endpoints based on DNS queries. It can be used to route traffic to different regions, availability zones, or data centers, based on proximity or performance. This is a good choice for global applications that need to route traffic based on location or performance.
Azure Front Door: This is a layer 7 load balancer that provides advanced traffic management features such as SSL offloading, URL-based routing, and session affinity. It can also perform application-level health checks and provides features such as a web application firewall and content delivery network (CDN) integration. This is a good choice for complex applications that require advanced traffic management and security features.
Microsoft Azure – Finding the Right Load Balancing Service
Pre-requisite: AZURE
We can divide incoming application traffic among many targets, such as Virtual Machines (VMs), containers, and IP addresses in our VPC, using Azure load balancer. The load balancer can increase the high availability of applications and decrease the latency for end users. Azure load balancer supports TCP and UDP protocols as well as HTTP/HTTPS and we can route the traffic to Private and Public IP addresses.
