We are living in a world where every other day we see a new technical innovation. For most of us mere mortal it is not easy to quickly figure out if the technology is worth our time. Making sense of new technical innovations is one of the core aspects of my current role so by taking the pain of writing this series I will help myself as well.
In this post, I will cover Dapr. Dapr stands for distributed application runtime.
What does distributed application runtime means?
These days most of us are developing distributed systems. If you are building an application that uses Microservices architecture then you are building a distributed system.
A distributed system is a collection of autonomous computing elements that appears to its users as a single coherent system.
Distributed application runtime provides you the facilities that you can use to build distributed systems. These facilities include:
- State management. Most applications need to talk to a datastore to store state. Common examples like PostgreSQL, Redis, etc.
- Pub/sub. For communication between different components and services.
- Service to service communication. This also includes retries, circuit breaking.
- Observability. To bring visibility into systems.
- Secret management. For storing password and keys.
- Many other
One important thing to note is that these are application level concerns. Distributed application runtime does not concern itself with infrastructure or network level concerns.Continue reading “Microsoft’s Distributed Application Runtime (Dapr)”
