| Deployment | The maker lists deployment on public clouds including AWS, Microsoft Azure, and Google Cloud Platform, as well as VCF, OpenStack private clouds, and on-premises. | Teradata documentation lists Teradata Cloud, public cloud, Teradata hardware, commodity hardware, and hybrid cloud as deployment options. |
| Integrations | The maker describes streaming ingestion with Tanzu Greenplum Streaming Server on Kubernetes and a certified standalone Apache NiFi connector for Greenplum 7. | Teradata’s developer portal demonstrates connections and workflows using JDBC, dbt, Teradata Parallel Transporter, and object storage such as AWS S3, Google GCS, and Azure Blob. |
| Purpose | Greenplum Database is an open-source, PostgreSQL-based data warehouse for analytics, machine learning, and AI. | Teradata Database is the core of the Teradata SQL Engine and supports complex analytic workloads using massively parallel processing. |
| Security | The maker states Tanzu Greenplum uses STIG hardening and FIPS 140-3 cryptographic modules for encryption at rest and in transit. | Teradata says it supports identity and access management, optional customer-managed encryption keys, and TLS 1.3 for client sessions. |
| Support | The project repository directs users to online documentation and its wiki for further information. | Teradata Support is a web-based 24x7 portal for documentation, software and patches, and case logging and tracking; maintenance support requires applicable agreements, licensing, and fees. |

In their own words
Greenplum Database
Greenplum Database is a PostgreSQL-based, open-source data warehouse for analytics, machine learning, and AI. Its architecture spreads data and query work across a cluster: a coordinator divides queries among segment servers. The project describes it for large analytical warehouses and business intelligence, including petabyte-scale data. Query planning can use GPORCA alongside the PostgreSQL-based planner. Storage options include append-optimized row and column formats, with compression for column storage. PXF connectors connect to Hadoop, object stores including Azure, Google Cloud Storage, MinIO, and S3, and SQL databases through JDBC. External tables can be queried or used to load outside data; PXF also supports querying Apache Iceberg foreign tables. Clients can connect through psql, ODBC, or JDBC. Greenplum is available as a free open-source project under Apache 2, while the commercial VMware Tanzu Greenplum offering is priced on request. It supports on-premises deployment and data lakes. Documented access control covers object privileges; row-level and column-level access controls are not supported.
