ElephantSQL is managed PostgreSQL servers in the cloud – hosted databases that let you store data in a structured way that can easily be accessed, managed, and updated.
PostgreSQL is an open source, object-relational database management system.
Database's primary function is to store data in a structured way. Databases can store very large numbers of records efficiently. The data is stored securely and it is possible for authenticated users to access, manage, delete and update the data. It is possible for multiple persons to access the same database at the same time. All the data can easily be sorted into a chosen way (e.g. by date or alphabetic) when it is accessed/selected from the database.
A connection is a TCP connection between your application and the PostgreSQL database.
A database will help you structure your data in a good way. It is very quick and easy to find information from a database, perform a search in the database and it is easy to add new data and to edit or delete old data. ElephantSQL provides hosting of PostgreSQL databases, meaning that ElephantSQL mange and maintaining the servers. Our monitoring tool will detect unhealty nodes and we automatically restart nodes if they become unavailable. We do daily backups of your data, it is easy to set up followers to your database and we keep a "write ahead log" of all changes to your database and stores the logs in multiple data centers. ElephantSQL has been running PostgreSQL servers for a long time. You can always trust us to know what to do if you run into problems. We also have extensive experience in monitoring of PostgreSQL servers.
A cloud-based database will increase the speed of getting the application to the market. Developers can focus on the core part of their applications, instead of managing and maintaining servers and handling backups.
Our customers are usually developers who want to focus on the core part of their applications, instead of managing and maintaining servers.
We have customers in a range from large enterprise business and startups to individual hobby developers.
You have some migration options between plans in ElephantSQL.
Fork: Easiest is to fork your database to a new server. This can also be done for plans with followers.
Backup and restore: Another option is to set up a new instance, take a backup of the old one and import your data into the new instance.
Pipe data: You also pipe your data to a new database:
pg_dump postgres://user:pass@host/db | psql postgres://user:pass@host2/newdb
You can delete an instance from the instances list page. If you remove an instance, all your databases, users, data and backup will be deleted and we will not be able to restore them.
You can create multiple databases on a dedicated server, Happy Hippo or Enormous Elephant.
It is only possible to manage databases and users on dedicated plans. Our dedicated plans are Happy Hippo and Enormous Elephant.
A follower to your database is another database that has a read-only copy of the master database. The follower will stay up-to-date with the master database data. All modification of the data, write/update/deletes are committed to the master database and the changes are streamed to the follower database.
You can use followers when you want to spread selects across multiple servers. Or you want to have a hot-standby ready to take over if you main database crashes.
Followers work by using PostgreSQL's built-in replication strategy.
On ElephantSQL is it easy to setup followers to your database. Go to the console page and press the follower tab and follow the instructions.
Automated backups are performed every day on all plans (pg_dump). These are stored in a cloud file storage so they are always accessible to you (same cloud as your instance). The backup is saved for 30 days. The last month backup files can be found and downloaded in the ElephanSQL Control Panel.
The backups are compressed with lzop, to restore the data you can usually use the following: lzop -cd "$FILE_NAME" | psql "$DATABASE_NAME"
Full server backups (base backup) are performed once a week, rolling WAL backups are performed every second minute.
If you are new to databases, we recommend you to read our beginner guide. It can be found here.
Another getting started guide can be found here. Once you have created your account you can get started querying and processing data by using any of the guides, depending on platform and language. These tutorials cover the basics of connecting your applications using ElephantSQL.
All clusters have nodes in multiple availability zones.

All plans are billed by the second, you can try out even the largest instance types for mere pennies. As soon as you delete the instance you won't be charged for it anymore, i.e. if you had a Happy Hippo (for $99/month) running for 15 days, then you will only be charged $49.50.
Billing occurs at the end of each month, and you are only charged for the time an instance has been available to you.
You can pay with Paypal, VISA, Mastercard or by Invoice/transfer. We do also accept Amex through PayPal. Contact us at firstname.lastname@example.org if you require invoicing. Payment options can be found under Billing information in the Control Panel.
