Pricing FAQs

How many users can I have on vFunction?

The vFunction platform has no limit on users, so as many architects and developers as possible can take advantage of its recommendations, insights, and automation. We price solely by the number of applications and services observed.

Does vFunction offer trials?

Yes, for application modernization we offer a 30-day free trial that you can request here or contact us. For microservices, we offer 14-day free trials, as well as a free option for up to ten services observed.

Does vFunction offer volume discounts?

Yes, as the number of applications or services increases the price per unit decreases. For application modernization, vFunction also offers discounts for packs of apps 10, 20, 30, 50+ including enterprise license agreements. Contact us to learn more. vFunction reserves the right to change pricing at any time.

Is vFunction on-prem or cloud-based?

vFunction is installed on-premises, so all your data remains secure and doesn’t leave your environment. In certain cases, where on-premises installation is not possible, or if your organization prefers a cloud version, vFunction can accommodate that request on a case by case basis.

Are training and services available for vFunction?

Yes, vFunction’s customer success team is available to help install, setup and support observability of your applications and train your team to optimize usage.

Architectural observability for governance

Does your solution apply only to microservices?

No. Architectural observability can be used for any distributed architecture, from distributed monoliths, macro-services all the way to microservices. The more services, the harder it is to get real-time documentation of your architecture so any of these environments will benefit from vFunction.

What agents does your solution use?

vFunction architectural observability uses the tracing data from OpenTelemetry (OTel) agents. If you already have OTel installed, you don’t need to install any additional agents. Simply spin up the vFunction server locally and you can be up and running within minutes.

What counts as a service for pricing?

Any instance that has an OTel agent would count as a service. Of course, the higher the number of services the deeper the discount per service is.

Architectural observability for modernization

What counts as an app?

For licensing purposes, vFunction defines each Java Virtual Machine (JVM) or common language runtime (CLR) as an application, with similar code bases counted once. Microservices are not considered separate applications for pricing. Although it makes sense to group them by business capability, we may enforce a “fair-use policy.” The ratio of total JVMs/CLRs to Business Applications shall not exceed 10:1.

How long does installation take?

The server installation generally takes about 30 minutes. Once installed, you’ll want to run the application in production or perform automatic testing in a QA or staging environment to cover as many system flows as possible. If no automatic testing is available, perform manual testing. This can take a few hours to one or two days until you meet sufficient coverage to achieve the starting point.

What languages does vFunction support?

vFunction supports Java applications (1.6+) and .NET applications (4.0+) A wide variety of application servers including Oracle WebLogic, IBM WebSphere, Tomcat, Red Hat JBoss, and more are supported along with a large number of JVMs and JDKs – see the support matrix document.
