Serverless Discovery
Summarize
Summary of Serverless Discovery
Serverless Discovery enables you to find application Configuration Items (CIs) on host machines without first discovering the host itself. It relies on infrastructure patterns to explore CIs, skipping the usual scanning and classification phases of traditional Discovery. There are two types of serverless Discovery: standard and host-based, both requiring infrastructure patterns but differing in their approach to locating CIs.

Key Features
- Standard Serverless Discovery: Discovers remote application CIs on unknown hosts without needing their IP addresses. It connects to remote resources using protocols like REST or HTTP by defining input parameters in an infrastructure pattern. Ideal for discovering web-based applications.
- Host-based Serverless Discovery: Discovers CIs residing on an already discovered host by using the host as a proxy. It does not run Discovery directly on the host but uses the host’s credentials to query CIs. This method suits scenarios where CIs lack IP addresses or are unknown. Infrastructure patterns specify operations such as WMI Queries without needing input parameters or additional credentials.
- Serverless Discovery Schedules: Serverless Discovery uses schedules rather than classifiers to trigger infrastructure patterns. The serverless schedule type lets you define input parameters for standard serverless Discovery or specify a host CI for host-based serverless Discovery, enabling flexible and targeted discovery runs.
Key Outcomes
- Efficient discovery of application CIs without prior host discovery, reducing discovery time and complexity.
- Ability to discover web-based applications remotely using standard serverless Discovery.
- Simplified discovery of CIs on known hosts without requiring additional credentials or IP addresses through host-based serverless Discovery.
- Improved control over discovery execution by using serverless schedules, allowing parameter customization and host targeting.
Discovery can find applications on host machines without the need to discover the host first. This type of Discovery is referred to as serverless Discovery.
Standard serverless Discovery
Standard serverless Discovery finds remote application CIs that reside on an unknown host. This type of serverless Discovery uses protocols, such as REST or HTTP, to find the CIs. The IP address of the host machine is not required. You define input parameters in an infrastructure pattern to connect to a remote resource. Use this type of Discovery when you want to discover web-based applications.
Host-based serverless Discovery
- You do not know the IP address of the CIs you want to discover, or the CIs do not actually have IP addresses.
- The CIs reside on an already discovered host CI.
For this type of Discovery, you also need an infrastructure pattern, but you do not need to define input parameters like you do for standard serverless Discovery. The pattern can specify operations, such as a WMI Query, which executes queries on a host. After Discovery connects to the host, it uses the credentials of the host to perform the Discovery of CIs you are exploring in the pattern. You do not need to specify additional credentials. When you run debug mode on the pattern, you can see the details under Temporary Variables on the pattern. You can then create pattern operations that make API calls from the host to the CIs you are trying to discover.
Serverless Discovery schedules
- Values for input parameters in the pattern if you are using standard serverless Discovery. See Create a schedule for standard serverless Discovery for instructions.
- A host CI if you are using proxy-host based Discovery. See Create a schedule for host-based serverless Discovery for more information.
