Would you like to discuss your environment with a knowledgable engineer?
We have a fairly large application running on 30 or so quad extra large boxes in EC2 and still having some difficulty managing peak spikes. When our dedicated load balancer gave way to inbound traffic, we approached aiScaler to assist us. They took on the task of understanding our requirements and work with us to configure and deploy aiScaler literally within minutes of initial request, in fact our DNS cutover from the dedicated load balancer took longer and since then, we have been happily in production without issue. Although we initially only looked at aiScaler as a sort of a stop gap load balancing software while put in a larger hardware load balancer in place, we have discovered that it does wonders with caching and has allowed us to remove half the nodes from our app server setup already. Oh and that dedicated hardware load balancer? We don’t have it anymore and no plans to acquire one. Thanks aiScaler.
We use aiScaler at Giant Digital in front of our load balanced AWS hosted servers on Scalr. Although occasionally we do experience high loads that spawn multiple DBs or web servers for the most part aiScaler deals with 99% of the traffic that’s thrown at it and this is for 20 million+ pages a month servers.

aiScaler has increased page load time dramatically. Installation was fairly smooth with minimal downtime. Configuration is straight-forward and there seem to be a plethora of advanced features we have yet to explore. The only suggestion I have is the implementation of a GUI for configuration changes. Otherwise, so far, so good. We are pleased with the service and initial support has been exceptional and responsive. While we are fairly new to aiScaler and have relatively limited experience, I have no reservations about highly recommending this product.
We were looking for something to help keep as much load as possible off our Windows origin servers. Our website is subject to extreme spikes in traffic, and there are many requests that can be cached. The caching layer needs to allow through requests with cookied sessions, while servering up cached versions of the same URLs to the general public. Varnishd and Nginx were both considered, and did basic caching well. But both were difficult to set-up, and responding to cookied sessions significantly reduced their maximum throughput. We’ve now used aiScaler during several large events, and the CPU is hardly pressed at all. The rules we put in place to respond to errors and downtime on origin servers has allowed us to maintain excellent uptime. The support from aiScaler had been excellent. They were able to create a new feature for us in under 24 hours, and we have never had a problem getting them on the line when we have questions. aiScaler is a great product for companies that require a caching layer, aiScaler server can handle a lot of traffic. With aiScaler supporting 250,000 req/s, the average website is going to take a long time before they hit a ceiling.
