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.
 

Amazon Elastic Load Balancing Pros review quotes

Spencer Malmad - PeerSpot reviewer

The feature that I like the most is the scalability. The solutions I build often have many pieces, which are very complicated. If a client comes to me with a design, my developer has made this as a template or a cloud formation script. It's a design on paper, and I want it executed a certain way. I can do that quickly and repeatedly with AWS. That is a considerable advantage because I can take that template and do it five times in different zones. That is an excellent feature based on a template, et cetera.

Amazon Elastic Load Balancing helps me efficiently distribute incoming application or network traffic across multiple targets, such as Amazon EC2 instances.

The best part about ALB is its ability to connect with different services including EC2, ECS, API Gateway, or Lambda functions, offering a lot of benefits like attaching a WAF.

Amazon Elastic Load Balancing Cons review quotes

Spencer Malmad - PeerSpot reviewer
Dec 1, 2022
The reporting could be simplified so that the client sees a report of what they cached at the end of the month and the number of hits. It should have metrics above and beyond their Google analytics, etc. You can't do that with the solutions from AWS. You have to build sophisticated cloud trails, reports, dashboards, etc. The setup is significant, and it's hard to manage. You'll need to hire someone or pay a consultant on a regular basis to manage it, and it's not for the faint of heart.

Improvements could involve making Amazon Elastic Load Balancing a global service, as currently, it is region-specific.

The ELB would benefit from allowing deployment in a single availability zone for test servers to avoid unnecessary costs.

It would be good if we had a product that integrates well with third-party vendors. Some of our customers want a multi-cloud solution. They don't want to be tied up to or be in just one cloud.
Aditya Mehta - PeerSpot reviewer

The solution needs to guarantee stability because multiple loads behind a load balancer can cause service unavailability.

The machines created by Amazon Elastic Load Balancing have different IP addresses, which we are not able to whitelist or predict.

The product's stability is an area with a slight shortcoming, which can be improved.
