To help you determine the AWS resources required for running your Datomic stack, we offer two topologies – Production and Solo – which you can select based on the operational characteristics your system needs. More details on topologies can be found in the Datomic Cloud Documentation.

Solo Topology

Starts as low as

The Solo Topology provides an inexpensive way to access Datomic's full programming model for development, testing, and hobby deployments. The Solo Topology provides:

  • the same programming model as Production
  • a single cluster node
  • smallest feasible instance size

Production Topology

Fully Scalable

The Production Topology is designed for production use. The Production Topology provides:

  • high availability with no single point of failure
  • horizontally scalable processing
  • load balancing
  • auto scaling
  • multiple query groups for different loads (e.g. transactional vs. analytic vs. developer queries)


Whether you’re experimenting with a proof-of-concept or running a mission-critical application, Datomic has a support plan to fit your needs. We’re here to help you do great things with Datomic.
