# DBaaS

DBaaS, E2E's Database as a Service, runs MySQL, MariaDB, or PostgreSQL for you. Each database server
you create is a DBaaS instance. Create one from MyAccount, and you get an endpoint and a port to
connect to with the username and password you set. You manage the data, and E2E runs the server
underneath it.

## What you can do

- [Create a DBaaS instance](/myaccount/database/how-to/create-a-database/) running MySQL, MariaDB,
  or PostgreSQL.
- [Connect to a DBaaS instance](/myaccount/database/how-to/connect-to-a-database/) with the client
  tool you already use.
- [Import a database into a DBaaS instance](/myaccount/database/how-to/import-a-database/) to move
  an existing application's data in, and
  [Manage database users on a DBaaS instance](/myaccount/database/how-to/manage-database-users/) to
  give each application its own user.
- [Start, stop, and restart a DBaaS instance](/myaccount/database/how-to/start-stop-and-restart-a-database/),
  and [Delete a DBaaS instance](/myaccount/database/how-to/delete-a-database/) when you have
  finished with it.
- [Move a DBaaS instance to another project](/myaccount/database/how-to/move-a-database-to-another-project/)
  in the same account.
- [Expand a DBaaS instance's disk space](/myaccount/database/how-to/expand-database-disk-space/) as
  your data grows, or
  [Upgrade a DBaaS instance's plan](/myaccount/database/how-to/upgrade-a-database-plan-or-version/)
  for more vCPUs and RAM.
- [Move a DBaaS instance to a newer engine version](/myaccount/database/how-to/move-to-a-newer-engine-version/)
  to run a newer release.
- [Whitelist an IP address for a DBaaS instance](/myaccount/database/how-to/whitelist-an-ip-address/)
  to choose which addresses can connect through the Endpoint, and
  [Attach a VPC to a DBaaS instance](/myaccount/database/how-to/attach-a-vpc-to-a-database/) for
  private access from your own network.
- [Monitor a DBaaS instance and set alerts](/myaccount/database/how-to/configure-a-database-alert/)
  to get an email when a metric meets a condition you set, and read its monitoring graphs and slow
  query log.
- [Back up and restore a DBaaS instance with snapshots](/myaccount/database/how-to/create-and-restore-a-snapshot/),
  or [Schedule automatic snapshots](/myaccount/database/how-to/schedule-automatic-snapshots/), for
  backup and recovery.
- [Export logs to Object Storage](/myaccount/database/how-to/export-logs-to-object-storage/) from a
  running DBaaS instance.
- [Create a Read Replica](/myaccount/database/how-to/create-a-read-replica/) to take read traffic
  off the primary DBaaS instance.
- [Enable SSL on a DBaaS instance](/myaccount/database/how-to/enable-ssl-on-a-database/) to encrypt
  the connection.
- [Create and edit a parameter group](/myaccount/parameter-group/how-to/create-and-edit-a-parameter-group/)
  to set engine configuration values.
- [Install a PostgreSQL extension](/myaccount/database/how-to/install-a-postgresql-extension/) to
  add an extension to a PostgreSQL DBaaS instance from its **Extensions** tab.
- [Convert a DBaaS instance to a committed plan](/myaccount/database/how-to/convert-a-database-to-a-committed-plan/)
  for a lower rate over a fixed period.

## Who it is for

Use DBaaS for any application that keeps its data in MySQL, MariaDB, or PostgreSQL. Common uses:

- The data layer of a web or mobile application. The application connects through the DBaaS
  instance's endpoint, and you choose which addresses can reach it with the whitelist, or privately
  from inside an attached VPC.
- Applications that read far more than they write. Up to four Read Replicas answer read queries,
  such as reports and dashboards, while the primary handles every change.
- A copy of your data in a second region. DBaaS runs in Delhi and Chennai, and a Read Replica in the
  other one can be promoted into an independent DBaaS instance when you need it. See [Read
  Replicas](/myaccount/database/concepts/read-replicas/) for what a replica in the other region
  needs.
- Teams that want managed backups. Take a snapshot while the DBaaS instance is running, or on a
  daily, weekly, or monthly schedule, and restore it into a new DBaaS instance.
- Applications with their own engine settings. A parameter group sets the engine configuration
  values once and applies them to the primary of every DBaaS instance it is attached to.
