# Guidelines for choosing optimization parameters

In this section, some guidelines on how to choose optimization parameters are provided for the following specific technologies:

* [Kubernetes](https://docs.akamas.io/akamas-docs/3.2.1-1/using-akamas/optimization-scenarios/optimizing-kubernetes)
* [JVM (OpenJDK)](https://docs.akamas.io/akamas-docs/3.2.1-1/using-akamas/optimization-scenarios/optimizing-jvm-layer-openjdk)
* [JVM (OpenJ9)](https://docs.akamas.io/akamas-docs/3.2.1-1/using-akamas/optimization-scenarios/optimizing-jvm-layer-openj9)
* [Oracle Database](https://docs.akamas.io/akamas-docs/3.2.1-1/using-akamas/optimization-scenarios/guidelines-for-optimizing-oracle-database)
* [PostgreSQL](https://docs.akamas.io/akamas-docs/3.2.1-1/using-akamas/optimization-scenarios/guidelines-for-optimizing-postgresql)

These guidelines also provide an example of how to approach the selection of parameters (and how to define the associated domains and constraints) in an optimization study.
