User Account and Authentication (UAA) is an identity management service in Cloud Foundry, used as an OAuth2 provider by the GE Predix platform. Being responsible for managing timed measurements, Time Series, in its turn, enables to efficiently and concurrently store data, as well as quickly retrieve it.

This post explains how to configure both services and to start using them in a sample Spring Boot app having two controllers (for querying and ingesting data).

.NET on Cloud Foundry, Part 1: Installation on Windows and Using Iron Foundry

Part 1 | Part 2 | Part 3

Creating .NET apps with Iron Foundry

PaaS has revolutionized the way applications are developed and deployed. With reduced delivery cycles and full automation, PaaS users can reach the market faster, significantly improving ROI and time-to-revenue. Cloud Foundry is one of the most popular open-source solutions for enterprises.

Until recently, .NET developers—who constitute a large part of software delivery folks—had rather limited access to Cloud Foundry’s services. The Iron Foundry project has corrected this imbalance by providing support for .NET on Cloud Foundry. It is not merely an extension, but an entire collection of tools and services .NET developers are used to working with, e.g. MS SQL and Message Bus-as-a-Service. Services can be bound to applications, so you do not have to worry about infrastructure and maintenance.

This post starts a series that will explore the capabilities of Iron Foundry. To show you how this platform works and try its services in action, I am going to create a validation prototype using a mixture of .NET and Node.js. I will rely on the Cloud-First approach in my investigation on how application interaction, management, and deployment are implemented in this platform. By the end of the series, you will have learned everything you need to know about creating .NET apps on Iron Foundry.
