General information#
It is recommended to read and understand this document. It will help you to find out what components LUNA PLATFORM consists of and what tasks they solve.
Deploy should be performed in the order specified in the document.
All the services can be divided into general and optional. You can't launch and use LP without general services, whereas optional services provide extra features and are not mandatory. Most of the services have their database or file storage.
General services

| Python Matcher | Performs matching tasks | |
| Faces | Creates faces, lists, and attributes. Stores these objects in the database. Allows other services to receive the required data from the database | PostgreSQL/ Oracle, Redis |
| Image Store | Stores samples, reports about long tasks execution, created clusters and additional metadata | Local storage/ Amazon S3 |

| Backport 4 | The service is used to process LUNA PLATFORM 4 requests using LUNA PLATFORM 5. | |
| User Interface 3 | User Interface is used to visually represent the features provided with the Backport 3 service. It does not include all the functionality available in LP 3. | |
| User Interface 4 | User Interface is used to visually represent the features provided with the Backport 4 service. It does not include all the functionality available in LP 4. | |
| Python Matcher Proxy | The service manages matching requests and routes them to Python Matcher or plugins. |
