O

Observation Period

For Turbonomic analysis, Observation Period is the time span of sampling for the data that is used to calculate utilization percentiles. You can set a Maximum Observation Period and a Minimum Observation Period.

The observation period impacts the analysis that Turbonomic uses to generate actions. A shorter period means analysis uses fewer data points to calculate utilization percentiles. This results in more dynamic, elastic resizing, while a longer period results in more stable or less elastic resizing.

OpenAPI

The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection (https://swagger.io/specification/).

The Turbonomic API is implemented using OpenAPI, and it uses Swagger as one way to deliver API documentation.

Orchestration

In system administration, Orchestration is the automated configuration, coordination, and management of computer systems and software. (Wikipedia definition, attributed to Thomas Erl. Service-Oriented Architecture: Concepts, Technology & Design. Prentice Hall, ISBN 0-13-185858-0: https://en.wikipedia.org/wiki/Orchestration_(computing)) Turbonomic supports orchestration via Action Scripts and via integrations with third-party orchestration vendors (see the Target Guide for more information).

In Turbonomic, you can create action automation policies that link to orchestration workflows as they recommend specific actions. Action scripts execute code that you create, while integrations with orchestrators execute workflows in their respective platforms.

OVA (Open Virtualization Appliance)

OVA is a file that contains a compressed, installable version of a virtual machine. One of the methods for deploying Turbonomic is via an OVA. When you open an OVA, it extracts the virtual machine (VM) and imports it into your datacenter. The Virtual Machine contains a complete instance of the Turbonomic platform.
