Hadoop, Big Data and BlueMix – a top introduction!

 IF you havent come across it Hadoop is an open-source software framework for storage and large-scale processing of data-sets on clusters of commodity hardware. Hadoop is an Apache top-level project being built and used by a global community of contributors and users.

All the modules in Hadoop are designed with a fundamental assumption that hardware failures (of individual machines, or racks of machines) are common and thus should be automatically handled in software by the framework

Now, here is a very interesting video – where we explore the relationship between BlueMix, Hadoop and unsurprisingly, Big Data – enjoy!

Magic zombies, tech talk and BlueMix !

HursleyFM (an up and coming podcast 🙂  ) talks to a legend of IBM Cloud Messaging Guy Barden. Guy talks us through the benefit to developers of BlueMix. And he should know, as he says, he breaks BlueMix so you dont have to!

A great chat – Guy magically appears around the 10 min mark… enjoy

 

Genius Hangout with Ben Mann, Nick Downs and a cast of dev stars giving a great overview of BlueMix

This Hangout was run just before Dev@Pulse and stars Ben Mann, Nick Downs and a star cast of developers for BlueMix. This is a particularly engaging video as the guys walk through the possibilities with BlueMix for developers.

Engaging, fun and informative – worth a watch

 

Battlefield 4 + Epic Win * Fun = IBM Cloud technology IBM Softlayer

You may not realise it but  development studio KUULUU and world’s largest online game servers provider Multiplay are using IBM SoftLayer’s cloud capabilities to power widely popular games such as Battlefield 4. Here’s the interesting thing, (to me anyway) Multiplay utilizes SoftLayer cloud to support the mega title Battlefield 4.

Battlefield 4 has a huge online following, and I am one of them. It’s a game which emphasises collaboration on a massive scale, clear thinking, teamwork over individual action and the fact that none of us are as good as all of us.

Sound familiar?

Check out the fun that can be had with teamwork and IBM Softlayer

If you have a PS4 and BF4 – im  j0nnymac_  im always up for a game!

 

Remember when we mentioned MQLight? Here we show how your app can be moved to BlueMix

Hey folks, we have mentioned the awesomeness of MQLight – and the awesomeness of BlueMix. What I wanted to do was link the two together in a single blog post.
For those not familiar with MQLight – here are a brace of dashing chaps that will give you the lowdown on MQLight as well as some collateral that will help you test your app’s runnimg locally

We have some great info on how to grab the goodies here – https://developer.ibm.com/messaging/mq-light/
But just to show you how simple it is to use – here is a node.js sample to receive a message:

var mqlight = require(‘mqlight’);
var recvClient = mqlight.createClient({service: ‘amqp://localhost’});
recvClient.on(‘connected’, function() {
recvClient.subscribe(‘news/technology’);
recvClient.on(‘message’, function(data, delivery) {
console.log(data);
});
});
recvClient.connect();

and to send:
var mqlight = require(‘mqlight’);
var sendClient = mqlight.createClient({service: ‘amqp://localhost’});
sendClient.on(‘connected’, function() {
sendClient.send(‘news/technology’, ‘Hello World!’);
});
sendClient.connect();

Now we are going to move forward into BlueMix – now a couple of legends Mark Phillips and Melanie Rao have made life easier for everyone by giving an account of how its done here – https://www.ibm.com/developerworks/library/ws-elasticmq-app/#N100E1

Basically the blog outlines a few simple steps to getting your MQLight goodies up and running in BlueMix

1. Familiarize yourself with the MQ Light JMS API, see Getting started with the MQ Light JMS API.

2. Download, deploy, and then run the JMS worker sample for MQ Light, for more information, see JMS worker application.

3. Download, deploy, and then run the JMS web application for MQ Light, for more information, see JMS web application.

4. You can write your own application for MQ Light, for more information, see Writing your own application.

5. When you have written your new application, you can deploy it, for more information see Deploying your own application.

Enjoy!

Ever wondered how BlueMix works?

A fantastic introduction into how BlueMix works. Originally broadcast back in April as part of the IBM Think Friday initiative. If you want to get a handle on how BlueMix works – this is a great place to start…

 

The awesome Ryan Baxter walks us through the BlueMix UI

This is one of the best hands on demonstrations i’ve seen of BlueMix. It’s approx 15 mins and is well worth a watch. Ryan Baxter is able to demonstrate how BlueMix’s functionality and services can easily be utilised to support your application.

Use your mobile phone to push JazzHub app’s into BlueMix – really!

This video, despite being a artily silent – clearly  demonstrates how easy it is to push a configured application to BlueMix from your phone using JazzHub. Who knew it was possible…

Robots! Spaceships! Node.js! JazzHub and BlueMix

OK – now check this out – a game built on MQTT and Node created by the legend Bryan Boyd who I am very proud to call a colleague.

The bots in the game were written in Node,  so the epic Ken adapted them to use JazzHub, then he deployed from there to BlueMix.

Now the game can very easily scale, and the difficulty of the game can be increased simply by changing the number of instances of the bots are running.

Awesome!!!
