If you’re running your applications in Amazon Web Services / EC2, you need some load balancing to make sure your web servers don’t get overloaded. Amazon offers Elastic Load Balancing (ELB) natively, but is it the best option for you? This blog explains the differences between Amazon ELB and Application Delivery Controllers (ADCs).
If you only need a basic load balancer to manage where to send and receive traffic within your AWS environment, then ELB might be enough. But if you’re running business-critical applications and you need to make sure they are always available, are running as fast as possible, are protected from attacks, and display real-time telemetry and performance data, then you might need additional functionality that ELB cannot provide. You might require a complete ADC like Snapt Aria, which provides a full-featured, high-performance software load balancer, web accelerator, WAF and GSLB.
