Achieving high availability in Temporal Cloud
Abstract
We envision a future where customers have complete autonomy over the execution of their workflows, including the ability to select isolation domains, regions, and cloud providers tailored to their unique availability needs. Our goal is to provide customers with control and configurability over resiliency and failover capabilities, enabling them to confidently achieve their performance and reliability objectives.
To realize this vision, we are expanding our suite of high-availability (HA) product offerings. Recognizing that not all use cases demand the same level of availability, we aim to deliver differentiated solutions that align with diverse business goals while maintaining customer control over outage mitigation. These offerings will address intrinsic business requirements, regulatory compliance (e.g., DORA for EU financial institutions), and peace of mind during incident management.
Customers will be empowered to choose the best HA solution for their specific needs based on factors such as use case criticality, application topology, cost considerations, and ease of adoption. This approach ensures flexibility while meeting the varying demands of modern workflows.
