Pros & Cons summary

Amazon Elastic Load Balancing integrates well with Amazon services, offering excellent scalability and robust security, including TLS. It efficiently distributes traffic, enhances application availability, and connects with EC2, ECS, API Gateway, and Lambda. Users appreciate path-based routing but note the need for better third-party integration, leaf-level certificate validation, enhanced security for external load balancing, and improved global accessibility. Integration with Terraform and routing policy enhancements are also necessary.

Prominent pros & cons

PROS

Amazon Elastic Load Balancing integrates well with Amazon Services and is highly configurable with features like TLS security.

The scalability of Amazon Elastic Load Balancing is highly appreciated, allowing users to replicate designs across different zones efficiently.

It offers reliable load balancing by distributing traffic to prevent overload and ensures application availability by routing requests to healthy instances.

Valuable features include rule prioritization, fast network load balancing, and effective security checks on instances.

Amazon Elastic Load Balancing is recommended for its flexibility and is ideal for connecting with other AWS services like EC2, ECS, and Lambda functions, also supporting WAF attachment.

CONS

Amazon Elastic Load Balancing lacks integration with third-party vendors, limiting multi-cloud capabilities.

Stability issues arise due to multiple loads behind the load balancer, which can cause service unavailability.

Pricing and cost management need improvement, as well as clarity in technical support fees.

Security concerns, including a lack of sufficient internal health monitoring and external protection, make it less suitable for critical applications.

Integration with Terraform and improvements in scripts for creating load balancers and target groups need enhancement.

The tool could enhance the internal load balancer with better health monitoring. The external load balancer needs more security parameters to protect it from the internet, as it currently lacks protection. It's okay for basic load balancing and those looking for basic functionality in an application load balancer. However, if someone is going to onboard a critical application, like in the banking sector, I wouldn't suggest Amazon Elastic Load Balancer because of security issues. There are no firewall restrictions.
