The portability of AlloyDB Omni lets it run in a wide variety of environments, including the following:\n\n\u003cbr /\u003e\n\n- Datacenters\n- Laptops\n- Cloud-based VM instances\n\nAlloyDB Omni is well-suited to the following scenarios:\n\n- You need a scalable and performant version of PostgreSQL, but you can't run a database in the cloud due to regulatory or data-sovereignty requirements.\n- You need a database that keeps running even when it is disconnected from the internet.\n- You want to physically locate your database as close as possible your users, in order to minimize latency.\n- You would like a way to migrate away from a legacy database, but without committing to a full cloud migration.\n\nAlloyDB Omni does not include AlloyDB features\nthat rely on operation within Google Cloud. If you want to upgrade your project\nto the fully managed scaling, security, and availability features of\nAlloyDB, you can migrate your AlloyDB Omni data\ninto an AlloyDB cluster just as you can with any other initial\ndata import.\n\nKey features\n------------\n\n- A PostgreSQL-compatible database server.\n- Support for [AlloyDB AI](https://cloud.google.com/alloydb/ai), an integrated set of capabilities built into AlloyDB, to help you build enterprise-grade generative AI applications using your operational data.\n- Integrations with the Google Cloud AI ecosystem including the [Vertex AI Model Garden](https://cloud.google.com/model-garden) and open source generative AI tools.\n- An [index advisor](/alloydb/docs/use-index-advisor) that analyzes frequently run queries and recommends new indexes for better query performance.\n- The AlloyDB [columnar engine](/alloydb/docs/columnar-engine/about), which keeps frequently queried data in an in-memory columnar format for faster performance on business intelligence, reporting, and hybrid transactional and analytical processing (HTAP) workloads.\n- Other optimizations and enhancements over a stock PostgreSQL server, like automatic memory management and [adaptive autovacuum](/alloydb/docs/adaptive-autovacuum) of stale data.\n\nHow AlloyDB Omni works\n----------------------\n\nAlloyDB Omni can be installed either as a standalone server or as part of a Kubernetes environment.\n\nAlloyDB Omni runs in a Docker container that\nyou [install onto your own environment](/alloydb/omni/15.5.2/docs/install) using a\ncommand-line program provided by Google. We recommend running\nAlloyDB Omni on a Linux system with SSD storage and at least 8 GB of memory per CPU.\n\nThe AlloyDB Omni Kubernetes Operator is an extension\nto the Kubernetes API that lets you run AlloyDB Omni in most\nCNCF-compliant Kubernetes environments. For more information, see\n[Install AlloyDB Omni on Kubernetes](/alloydb/omni/15.5.2/docs/deploy-kubernetes).\n\nYour applications connect to and communicate with your\nAlloyDB Omni installation exactly as they would with an ordinary\nPostgreSQL database server. User access control relies on PostgreSQL standards,\nas well.\n\nYou can configure the behavior of AlloyDB Omni using the [same\ndatabase flags that are available to\nAlloyDB](/alloydb/docs/reference/database-flags).\n\nDocumentation for the latest version of AlloyDB Omni\n----------------------------------------------------\n\nFor information about the latest version of AlloyDB Omni, refer to the [AlloyDB Omni documentation set](/alloydb/docs/omni).\n\nWhat's next\n-----------\n\n- [Quickstart: Install AlloyDB Omni on Debian or Ubuntu](/alloydb/omni/15.5.2/docs/quickstart)\n\n- [Customize your AlloyDB Omni installation](/alloydb/omni/15.5.2/docs/install)"]]
