Twilio provides an awesome SMS and telephony service that you can use in web applications. . I’d been wanting to build an application with Twilio for a while now, and finally did it the other day. It’s called zip-weather. The app will respond to text messages and voice calls, prompt you for a location, then provide a weather forecast for that location.
I just posted an entry on my personal blog titled "enabling New Relic in a Cloud Foundry node application", which walks through enabling a node.js application with the New Relic monitoring service. As this enablement is generic to Cloud Foundry, it will of course work with Bluemix, and I've enabled one of my Bluemix apps - node-stuff - to make use of it.
As a followup to my last post for deploying Ghost.js on IBM codename:BlueMix, I would like to share a follow-up technique which utilizes a Cloudant CouchDB instance as a persistent image datastore.
CloudTrader is a Java EE application that simulates an online stock trading system. This application enables users to log in, view their portfolio, lookup stock quotes, and buy or sell stock shares. It is built primarily with Java Servlets, JSPs, and JavaBeans. CloudTrader was created by making changes on top of a ten year old DayTrader benchmark application to showcase how you can migrate an existing application to BlueMix and revitalize it with services in Bluemix.
This article will use a BlueMix JPA Sample Application with a db2 or mysql database driven by either EJBs or Servlets. JPA (Java Persistence Architecture API) is a set of APIs that is used for reading and writing data to databases via Java objects. An EJB (Enterprise Java Bean) is a server side Java object that contains business logic with special qualities of service (collaborators) such as transactions and security. We’ll provide some code snippets for EJBs and JPA, and also explain the packaging required for deploying this type of application to BlueMix.
As a follow up to my previous blog post, where I showed how to set up a real-time console log web tail for your Node.js application, I will be demonstrating how to use socket.io to instrument a web application. This is not meant for production level code, but instead to serve as an example of how a developer could instrument their web application in a few short steps and how they could expand it without much effort.
