A few weeks ago, we announced the preview availability of the new Basic and Premium Elastic Database Pools Tiers with our Azure SQL Database service. Elastic Database Pools enable you to run multiple, isolated and independent databases that can be auto-scaled automatically across a private pool of resources dedicated to just you and your apps. This provides a great way for software-as-a-service (SaaS) developers to better isolate their individual customers in an economical way.
Today, we are announcing some nice changes to the pricing structure of Elastic Database Pools as well as changes to the density of elastic databases within a pool. These changes make it even more attractive to use Elastic Database Pools to build your applications.
Specifically, we are making the following changes:
- Finalizing the eDTU price – With Elastic Database Pools you purchase units of capacity that we can call eDTUs – which you can then use to run multiple databases within a pool. We have decided to not increase the price of eDTUs as we go from preview->GA. This means that you’ll be able to pay a much lower price (about 50% less) for eDTUs than many developers expected.
- Eliminating the per-database fee – In additional to lower eDTU prices, we are also eliminating the fee per database that we have had with the preview. This means you no longer need to pay a per-database charge to use an Elastic Database Pool, and makes the pricing much more attractive for scenarios where you want to have lots of small databases.
- Pool density – We are announcing increased density limits that enable you to run many more databases per Elastic Database pool. See the chart below under “Maximum databases per pool” for specifics. This change will take effect at the time of general availability, but you can design your apps around these numbers. The increase pool density limits will make Elastic Database Pools event more attractive.
Below are the updated parameters for each of the Elastic Database Pool options with these new changes:
