Top 10 Interview Questions for IBM Bluemix
by Bhavya Sri
1.what is Bluemix?
Lets go by the definition mentioned in the documentation itself.“IBM® Bluemix™ is an open-standards, cloud-based platform for building, managing, and running apps of all types, such as web, mobile, big data, and smart devices. Capabilities include Java, mobile back-end development, and application monitoring, as well as features from ecosystem partners and open source—all provided as-a-service in the cloud. “Bluemix is a platform as a service (PaaS) offering based on the Cloud Foundry open source project that promises to deliver enterprise-level features and services that are easy to integrate into cloud applications. Since it is based upon Cloud Foundry (open source platform as a service) so you can tap into the growing ecosystem of frameworks and services.2. Why did you choose to be a developer?Guess it is in my genes (laughs). I mean, being a business analyst was a foolish move I once made. Plus, being a developer makes me feel like a film director. The product I develop is my movie and I give it my personal touch. I don’t think any other role would have given me as much happiness as being a developer does. Also, it gives me awesome money (winks).
3. What made you choose Bluemix?Somewhere in the second quarter of the year, Social media was raining Bluemix. It quickly caught my attention and I started exploring it. Once logged in, I was thoroughly impressed to see the way things were organized in the dashboard and with each click grew my curiosity to learn more!I clicked the catalog and wow! It had a set of boiler plates that helps one get started in no time. After having played with a couple of boiler plate apps, I started exploring the various services provided by Bluemix. RapidApps grabbed my attention. With RapidApps on Bluemix, I was ready with my first App deployed and running in less than 15 mins! It was unbelievable! I was so excited with the ease of its usage that I started publishing tutorials.4. We have heard a lot about the ease of using Bluemix. Tell us your experience as a Bluemix user.The Could Foundary command line tool along with Bluemix dashboard makes a great combination for developers to quickly develop and deploy their application onto Bluemix.
