Dimensions summary
This is a free listing, so the software carries no charge from the vendor. You pay only for the AWS EC2 instance you run it on. Pricing is organized by instance size, letting you match compute to your load balancing needs. You can choose from smaller burstable instances (t3.small, t3.medium, t3.large) or general-purpose and compute-optimized options (m5.large, c5.large). Larger instances provide more processing and memory capacity. Billing is hourly per running instance, with no upfront commitment, so costs track actual usage. Select the size that fits your expected traffic and performance requirements.
Top-of-mind questions for buyers
Each instance size maps to an AWS EC2 configuration with set processing and memory. The t3 sizes (small, medium, large) are burstable, suited to variable or lighter traffic. The m5.large is general-purpose and c5.large is compute-optimized, providing steadier capacity for heavier or sustained traffic.
The software itself is free, so no vendor charge applies. Hourly billing tracks the running EC2 instance. A stopped instance stops accruing compute charges, though attached AWS storage may still incur fees. Costs track actual running time, with no upfront commitment.
You pay only the AWS EC2 compute cost for the instance size you select. The LoadMaster software carries no vendor charge on this listing. Advanced features and support subscriptions are licensed separately through the vendor and are not part of this free listing.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources.
