QuerySurge AI provides a flexible implementation with 2 models – Cloud and Core. Whether you require rapid cloud deployment or an on-premises model for complete control, QuerySurge AI offers two powerful implementation options tailored to your specific needs.

• QuerySurge AI Cloud is fully hosted in the cloud, requires no hardware, provides rapid deployment with minimal setup, and is ideal for teams seeking fast results with minimal IT overhead.
• QuerySurge AI Core is installed within your environment, provides full control over your data and configuration, requires server installation (it runs on GPUs or CPUs), and is designed for organizations with strict compliance or security policies.

QuerySurge consists of the following components:

1. The QuerySurge Application Server (Tomcat)
2. The QuerySurge Database (MySQL)
3. QuerySurge Agent(s) – a minimum of one must be deployed
4. QuerySurge Execution API (optional)
   

For more information and a detailed look at the QuerySurge product Architecture components, see this page: http://www.querysurge.com/product-tour/product-architecture

The QuerySurge Agent is the component of the architecture that actually executes queries against Source and Target data sources, returning the results to QuerySurge. Agents are deployed in a hub-and-spoke relationship to the QuerySurge application server, as you can see in the QuerySurge product architecture diagram.

For a QuerySurge Trial or a POC, one agent is normally sufficient.

For production deployment, the answer is dependent on multiple factors (your Source/Target data base/data source products, the hardware Source/Target are deployed on, your style of query-writing), and is best determined as you gain more experience with QuerySurge in your own environment.

Nope! QuerySurge comes with its own embedded database. We handle the database licensing, so deploying QuerySurge will not affect any licensing that your organization currently has.

For a QuerySurge trial, the specifications can be found here>>

Our recommended production deployment specifications can be found here>>

No – in fact, we do not recommend deploying Agents on your database servers.

Agents should be deployed in your environment in a hub-and-spoke relationship to the QuerySurge application server. Any boxes or VMs with sufficient resources (see questions above) to perform QuerySurge tasks can be used, including the Testers’ desktops.

Yes. If you deployed your Trial installation on the same hardware as you plan for your production QuerySurge installation, you’re all set – all we need to do is apply your new license to your existing QuerySurge instance. Everything else stays the same.
If you need to move your queries from your trial QuerySurge instance to your “permanent” QuerySurge installation, please contact us or get in touch with your account manager. We’ll be happy to help you!
