Tech Lead Journal
Platform Engineering Best Practices
Preeti outlines platform engineering lessons: close user collaboration, targeted use cases, developer relations, and visibility tactics.
How much of your code exists only to prevent failures? Discover a new paradigm for building reliable applications.
In this episode, Preeti Somal, SVP at Temporal, explores a paradigm shift that can dramatically boost productivity and give developers peace of mind. Drawing on her experience leading massive infrastructure at Yahoo and HashiCorp, she explains Temporal’s concept of durable execution that helps developers focus on business logic and remove reliability concerns. Preeti also discusses key findings from Temporal’s first State of Development Report.
In this episode, you will learn about:
- Lessons from operating large-scale systems at Yahoo and HashiCorp
- Why reliability ranks higher than cost for most engineering teams
- How durable execution removes reliability complexity from developer concerns
- Why unlearning old patterns proves harder than learning Temporal’s model
- Creating a strong incident response culture through blameless post-mortem
- Nurturing psychological safety in infrastructure teams and on-call engineers
- Building security and compliance from day one versus retrofitting later
