Best of Bluemix: Elastic apps, iOS8 games, and 5 advantages for developers

Share this post:

best of bluemix This weekly post showcases some of the best new tutorials, videos, and other content published each week on developerWorks.

  • Create an iOS 8 game with React Native and Advanced Mobile Access
    Learn how you can create a React Native game that takes advantage of Advanced Mobile Access and the Cloudant NoSQL DB, both available as services on IBM Bluemix. The game shows the construction of a React Native app and illustrates techniques such as tweening and animation. And it shows how to integrate Advanced Mobile Access features into a React Native–based iOS 8 application. You’ll see how straightforward it is to integrate Bluemix MobileFirst platform features into existing or new iOS apps developed with React Native to add access tracking, cloud storage, log capture, and other scalable back-end services to your apps today.
  • Bluemix fundamentals: 5 key advantages, from a developers’ perspective
    In this short video, Bobby Woolf summarizes the main benefits and advantages that Bluemix has over other cloud development platforms.
  • Make your application elastic on Bluemix
    With Bluemix Auto-Scaling, you can scale out your application instances seamlessly during peak times to handle increased workloads and then decrease the application instances automatically after the peak time to keep a reasonable capacity and minimize the costs.

    To illustrate how the service works, you’ll start with a simple, web-based Java app that simulates high memory usage. The app runs on the Bluemix Liberty for Java runtime. You’ll set an auto-scaling policy that includes an upper and lower threshold and uses the Jmeter tool to increase the workload on the app. From the auto-scaling dashboard, you can monitor the growth of memory usage. When it reaches the specified upper threshold, an instance is added, the app scales to two instances, the workload is balanced between the two instances, and the app runs safely under the increased workload.

Check out the Bluemix page on developerWorks for more great how-to and introductory content on Bluemix, including quick-starts, a list of tutorials available for each Bluemix service, and more.
