Training Example: Dapr – Review the Data, Give Your Score & Compare to the Real AI Evaluation

[H3] Service invocation
Service invocation enables applications to communicate with each other through well-known endpoints in the form of http or gRPC messages. Dapr provides an endpoint that acts as a combination of a reverse proxy with built-in service discovery, while leveraging built-in distributed tracing and error handling.
> Read more about Service invocation

[H3] Publish subscribe
Pub/Sub is a loosely coupled messaging pattern where senders (or publishers) publish messages to a topic, to which subscribers subscribe. Dapr supports the pub/sub pattern between applications.
> Read more about Publish subscribe

[H3] State management
Application state is anything an application wants to preserve beyond a single session. Dapr provides a key/value-based state and query APIs with pluggable state stores for persistence.
> Read more about State management

[H3] Actors
An actor is an isolated, independent unit of compute and state with single-threaded execution. Dapr provides an actor implementation based on the virtual actor pattern which provides a single-threaded programming model and where actors are garbage collected when not in use.
> Read more about Actors

[H3] Workflow
The Workflow API enables you to define long running, persistent processes or data flows that span multiple microservices using Dapr workflows or workflow components. The Workflow API can be combined with other Dapr API building blocks.
> Read more about Workflow

[H3] Jobs
Many applications require job scheduling, the need to take an action in the future. The jobs API is an orchestrator for scheduling these jobs in the future, either at a specific time or a specific interval.
> Read more about Jobs

[H3] Secrets
Dapr provides a secrets API and integrates with secret stores such as public cloud stores, local stores and Kubernetes to store the secrets. Services can call the secrets API to retrieve secrets, for example to get a connection string to a database.
> Read more about Secrets

[H3] External configuration
The Configuration API enables you to retrieve and subscribe to application configuration items for supported configuration stores. This enables an application to retrieve specific configuration information, for example, at start up or when configuration changes are made in the store.
> Read more about External configuration

[H3] Bindings
A binding provides a bi-directional connection to an external cloud/on-premise service or system. Dapr allows you to invoke the external service through the Dapr binding API, and it allows your application to be triggered by events sent by the connected service.
> Read more about Bindings

[H3] LLM Conversation
The conversation API reduces the complexity of securely and reliably interacting with Large Language Models (LLM) at scale. The API includes prompt caching, and PII obfuscation to prevent sending sensitive information to the LLM.
> Read more about LLM Conversation

[H3] Distributed lock
The distributed lock API enables you to take a lock on a resource so that multiple instances of an application can access the resource without conflicts and provide consistency guarantees.
> Read more about Distributed lock

[H3] Cryptography
With the cryptography API, you can leverage cryptography in a safe and consistent way. Dapr exposes APIs that allow you to perform operations, such as encrypting and decrypting messages, within key vaults or the Dapr sidecar, without exposing cryptographic keys to your application.
> Read more about Cryptography

How DeFacto migrated to an event-driven architecture
"In a short time, as a result of adopting Dapr, DeFacto’s developers rapidly deployed a significant number of services into all environments. With multiple development teams working on different scopes and solution areas, interdependencies between services under the control of different teams added further complexity to the development process. However, Dapr’s service invocation API building block streamlined the development process by simplifying the discoverability and calling between multiple services."
