## What it is
Steeltoe is a collection of .NET libraries that add cloud-native microservices capabilities such as externalized configuration, service discovery, distributed tracing, management endpoints, security, and database connectors. It integrates .NET applications with Spring/Spring Boot ecosystems, Cloud Foundry, Kubernetes, and Tanzu platforms.

## Use cases
- build .NET microservices with Spring Cloud Config Server externalized configuration
- register and discover services with Netflix Eureka or Consul from a .NET app
- add Spring Boot actuator-style management endpoints to ASP.NET Core
- change log levels at runtime and export metrics to Prometheus
- connect .NET apps to PostgreSQL, MySQL, Redis, MongoDB, RabbitMQ or Cosmos DB in the cloud
- add single sign-on JWT and certificate auth with Cloud Foundry
- add distributed tracing to .NET microservice logs

## When to choose
- you're building or modernizing .NET microservices that must integrate with Spring Boot or Cloud Foundry environments
- you need Spring Cloud-style features (config server, Eureka, actuators) in .NET
- you're deploying .NET apps to Kubernetes, Cloud Foundry, or Tanzu and want service discovery, config, and management out of the box

## When to avoid
- you're building a simple monolith with no cloud or microservices requirements
- your stack is not .NET (Steeltoe is C#/.NET only)
- you prefer assembling individual libraries yourself rather than adopting an integrated framework

## Facets
