Build a Real Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB 2.0 – Part III

By September 11, 2012

In Part II of this series, we covered the architecture needed for persisting the Activity Streams to MongoDB and fanning it out in real-time to all the clients using Redis PubSub. Since then, some exciting new Node.js features for Cloud Foundry were launched. In addition, the MongoDB version on Cloud Foundry has been upgraded to 2.0. In this … Continue reading “Build a Real Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB 2.0 – Part III”

New Runtime Module for Node.js Applications

By August 21, 2012

In the previous blog post, Cloud Foundry Now Supports Auto-Reconfiguration for Node.js Applications, we saw that Node.js applications deployed to CloudFoundry.com can be automatically reconfigured to connect to Cloud Foundry services. However, there may be situations where you want to opt-out of that feature to have finer control over service connections or to overcome its limitations. In those … Continue reading “New Runtime Module for Node.js Applications”

Cloud Foundry Now Supports Auto-Reconfiguration for Node.js Applications

By August 14, 2012

Cloud Foundry has long supported auto-reconfiguration for Spring and Ruby applications. Now we are pleased to add auto-reconfiguration support for Node.js applications as well. Deploying Node.js applications to Cloud Foundry previously required parsing of environmental variables and overwriting server and service connection function calls to use Cloud Foundry specific parameters. This approach was not intuitive to developers who just … Continue reading “Cloud Foundry Now Supports Auto-Reconfiguration for Node.js Applications”

Building a Real-Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB–Part II

By June 5, 2012

In Part I of this series, we showed how to start from the node-express-boilerplate app for real-time messaging and integration with third parties and move towards building an Activity Streams Application via Cloud Foundry. The previous app only sent simple text messages between client and server, but an Activity Streams Application processes, aggregates and renders … Continue reading “Building a Real-Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB–Part II”

Building a Real Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB – Part I

By May 17, 2012

Cloud Foundry provides developers with several choices of frameworks, application infrastructure services and deployment clouds. This approach to providing a platform as a service enables the fast creation of useful cloud applications that take advantage of polyglot programming and multiple data services. As an example of how this enables us to be more productive, I was able … Continue reading “Building a Real Time Activity Stream on Cloud Foundry with Node.js, Redis and MongoDB – Part I”
