## What it is
Azure Load Testing provisions managed load infrastructure and integrates test results with Azure workflows. It supports Apache JMeter tests and CI/CD automation.

## Choose it when
- Teams that want managed load generation without operating injectors
- Organizations budgeting for commercial licenses or subscriptions
- Groups comfortable scripting in Java, Groovy

## Look elsewhere when
- Strictly air-gapped environments with no approved cloud path
- Projects that require a fully free open-source stack only

## Architecture
Azure Load Testing runs as a cloud service: scenarios use Java, Groovy, while generators and orchestration are vendor-managed.

## Pricing
Azure Load Testing follows a pay-as-you-go model based on Virtual User Hour (VUH) consumption, with no monthly resource fees. Consumption beyond 10,000 VUH is priced at $0.06 per VUH. Users only pay for the VUH consumed during test runs. Minimum VUH per test run applies.

## FAQ
### Who is Azure Load Testing for?
Azure Load Testing is best for teams that want managed load generation without operating generators themselves. It is commercial software, typically licensed for larger or governed programs. Vendor: Microsoft. Deployment model: cloud. Azure consumption-based pricing with free quota. Confirm details against the official site and a short proof-of-concept in your environment.

### How does Azure Load Testing differ from Apica?
Compared with Apica, scripting centers on Java, Groovy rather than JavaScript. Azure Load Testing lists protocols HTTP, HTTPS, JDBC, JMS; Apica lists HTTP, HTTPS, REST. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.

### What scripting language and concurrency model does Azure Load Testing use?
Azure Load Testing uses Java, Groovy for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Browser. Protocols: HTTP, HTTPS, JDBC, JMS. Match these to how your team already authors tests and which systems you must drive under load.

### What is the cloud or enterprise path for Azure Load Testing?
Azure Load Testing is cloud-hosted: you run tests on vendor-managed infrastructure without operating load generators yourself. That usually speeds ramp-up for distributed load while shifting capacity planning and data residency to the vendor. Pricing model: Azure consumption-based pricing with free quota.

### What are known limitations of Azure Load Testing?
Azure Load Testing limitations to weigh: cloud services trade operational simplicity for vendor pricing, data residency, and network path differences versus your production topology; commercial licensing and quotes can gate large-scale or enterprise use. Status: active. Always validate against your target protocols and scale with a proof-of-concept.
