Durable Execution: A Revolutionary Abstraction for Building Resilient Applications

Is 90% of your code just for resiliency? Learn how durable execution separates business logic from infrastructure, letting you write simpler, more reliable applications.

Choosing the right abstraction to reduce software complexity

Modern applications often suffer from accidental complexity where resiliency code is mixed with business logic, creating a 'smoothie architecture'.

Why database transactions make monoliths simpler

Monoliths are often simpler than microservices because database transactions eliminate the need to handle partial failures, a major source of complexity.

#3about 3 minutes

The hidden costs and challenges of event-driven architectures

Event-driven architectures introduce problems like unclear APIs, scattered business logic, poor error handling, and low visibility into system state.

#4about 2 minutes

Why events are the global variables of distributed systems

Events create high design-time coupling because changing a producer's event can unknowingly break multiple downstream consumers, similar to changing a global variable.

Introducing durable execution as a new programming model

Durable execution is an abstraction where code is guaranteed to run to completion by resurrecting its execution state after process crashes or infrastructure failures.

#6about 4 minutes

How durable execution simplifies complex application logic

Durable execution encapsulates complexity by providing durable local variables, long-running functions, infinite retries, and simplified asynchronous communication.

#7about 1 minute

Implementing a subscription model with durable execution

A long-running subscription workflow can be implemented in just a few lines of pure business logic using durable execution, eliminating boilerplate code.

#8about 4 minutes

How durable execution is implemented using event sourcing

The state of a durable execution is recovered by replaying a stored history of external events, which deterministically reconstructs the application's state without serialization.

#9about 1 minute

Essential platform features for durable execution

A complete durable execution platform requires features beyond the core abstraction, including uniqueness constraints, signaling, querying, indexing, and versioning.

Introducing Temporal as an open source implementation

Temporal is a scalable, open-source platform that provides a production-ready implementation of the durable execution model for building resilient applications.
