General questions about Managed Service for Greenplum®
What is Managed Service for Greenplum®?
Managed Service for Greenplum® is a service that helps you create, operate, and scale Greenplum® databases in a cloud infrastructure.
With Managed Service for Greenplum®, you can:

What part of database management and maintenance is Managed Service for Greenplum® responsible for?
When creating clusters, Managed Service for Greenplum® allocates resources, installs the DBMS, and creates databases.
For the created and running databases, Managed Service for Greenplum® automatically creates backups and applies fixes and updates to the DBMS.
Managed Service for Greenplum® also provides data replication between database hosts (both inside and between availability zones) and automatically switches the load over to a backup replica in the event of a failure.
Which tasks are best addressed using Managed Service for Greenplum®, and which using VMs with databases?
Yandex Cloud offers two ways to work with databases:
- Managed Service for Greenplum® allows you to operate template databases with no need to worry about administration.
- Yandex Compute Cloud virtual machines allow you to create and configure your own databases. This approach allows you to use any database management systems, access databases via SSH, and so on.
How do I get started with Managed Service for Greenplum®?
Managed Service for Greenplum® is available to any registered Yandex Cloud user.

What happens when a new DBMS version is released?
The database software is updated when new minor versions are released. Owners of the affected DB clusters are notified of expected work times and DB availability in advance.
What happens when a DBMS version becomes deprecated?
