### Abstract

Building a reliable application is often a journey driven by the evolution of requirements and the risk tolerance of the business. Along the way, there are important decisions to make, as well as some key inflection points, such as transitioning from a single instance to a redundant setup. Redundancy enhances resilience but also adds complexities of coordination and data replication. In this talk, Sergey shares how we at Temporal we think about application reliability, along with the relevant patterns, tools, and trade-offs involved.
