Tessell for PostgreSQL

This in-depth guide discusses the features of Tessell for PostgreSQL and how the service handles planned maintenance events and unplanned outages, including the advantages and controls available to help you minimize application downtime. We will cover the availability of single-zone Tessell instances, the advantages of a regional HA Tessell deployment, and present an architecture to address disaster recovery requirements. Each architecture builds on top of the previous deployment method while improving the availability of the Tessell service. In other words, the Tessell HA architecture provides the capabilities of a single-zone Tessell instance deployment, plus additional availability characteristics. We will also briefly discuss the requirements of the applications to manage various outage events.
