What is OpenStack? What is Trove?


The OpenStack Mission: to produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable.

OpenStack is open source, openly designed, openly developed by an opencommunity.

https://wiki.openstack.org/wiki/Main_Page

The OpenStack Open Source Database as a Service Mission: To provide scalable and reliable Cloud Database as a Service provisioning functionality for both relational and non-relational database engines, and to continue to improve its fully-featured and extensible open source framework.

OpenStack Trove Architecture


Trove Functionality

• Provisioning– Single instances, Replicated groups, Clusters

• Backup and Restore• Replication• Clustering• Database configuration management• Resizing instances and storage


Why this makes sense

• Databases are complex– Setup is complex and unforgiving– Failure modes are complex– Configuration options are numerous

• Data Loss and Data Security are paramount• There are a number of databases in the organization

– SQL, NoSQL, Relational, Object Store, Graph, Key-Value, …– Expertise is often fragmented


What Trove offers

• A common API for standard operations– Across all databases

• Abstractions for popular database constructs– Replication, Clustering, HA

• Management and Data plan clearly isolated– Applications have direct database access

• Integrates best practices for each database– Built into Trove


Provisioning workflow (single instance)


Generate a database backup


Provisioning workflow (from a backup)


Provision a database replica


Provision a database cluster


Apply a configuration change

Database support


MySQL Percona including PXC MariaDB

Cassandra MongoDB Redis

PostgreSQL Couchbase CouchDB

Vertica DB2 Express Oracle 11g and Oracle 12c*
