Deploying and configuring PGD on Hybrid Manager
===============================================

EDB Postgres AI Hybrid Manager (HM) is the centralized control plane for
the EDB Postgres AI platform, providing additional value such as Oracle
compatibility via EDB Postgres Advanced Server and Transparent Data
Encryption (TDE) using either EDB Postgres Extended or Advanced Server.
It allows you to deploy and manage the full lifecycle of PGD-powered
clusters through two primary configurations: Advanced High Availability
(AHA) and Distributed High-Availability (DHA).

The primary distinction between these configurations lies in their
scalability and group architecture:

- **Distributed High-Availability (DHA):** Designed for global scale and
  geographic redundancy, this configuration supports multiple data
  groups. This allows for distributed workloads across different
  locations or regions.

- **Advanced High Availability (AHA):** Designed for localized
  resilience, this configuration consists of a single data group. It is
  ideal for high availability within a single region or data center.

Detailed comparisons of these architectures, including resource
requirements and recommended use cases, are provided within the Hybrid
Manager console during the cluster creation process.

`Creating a database cluster <https://www.enterprisedb.com/docs/edb-postgres-ai/latest/hybrid-manager/using_hybrid_manager/cluster_management/create-clusters/>`_  for step-by-step instructions on deploying these
high-availability configurations.
