Mobile SOA with Tuscany Android

In Apache Tuscany, we have been experimenting with Google Android Platform to build Mobile SOA Applications

In Apache Tuscany, we have been experimenting with Google Android Platform to build Mobile SOA Applications, and we now have couple Android based samples that demonstrate a Android mobile application consuming SCA services available on the cloud.

Store-android: A front end to our "Store Getting Started Guide" that consumes the catalog and shopping cart services and allow you to shop for fruits and vegetables.

SCATour-android: A front end to the "SCA Tour" scenario that allows you to search for trips direct from your Android phone.

If you are reading here, you are interested on this topic and might want to get hands-on and run this applications... below are the necessary steps to get the Tuscany/Android sample applications running:

1) Install Android SDK following the steps described in Android SDK Installation Guide:

curl -O http://dl.google.com/android/android-sdk-mac_x86-1.5_r2.zip
unzip android-sdk-mac_x86-1.5_r2.zip


2) Install Android Eclipse Plugins (Android DDMS and Android Development Tools):

- Start Eclipse, then select Help > Software Updates....
- In the dialog that appears, click the Available Software tab.
- Click Add Site...
- Enter the Location below and click Ok:

https://dl-ssl.google.com/android/eclipse/


- Back in the Available Software view, you should see the plugin listed by the URL, with "Developer Tools" nested within it. Select the checkbox next to Developer Tools and click Install...
- On the subsequent Install window, "Android DDMS" and "Android Development Tools" should both be checked. Click Next.
- Read and accept the license agreement, then click Finish.
- Restart Eclipse.

3) Create a Android Virtual Device (AVD)

cd ~/opt/android-sdk-mac_x86-1.5_r2/tools
android create avd --name android-1.1 --target 1
android create avd --name android-1.5 --target 2


4) Configure the Android Eclipse Plugins to point to the Android SDK

- Start Eclipse, then select Eclipse->Preferences->Android
- Point to the directory where you installed the Android SDK in step 1.


You you should be ready to run Android applications. Now let's add the Tuscany Android samples to your Eclipse IDE and run it.

1) Checkout Tuscany code and create Eclipse IDE project for the samples we are going to use :

svn co http://svn.apache.org/repos/asf/tuscany/sca-java-1.x/trunk/ java-1.x
cd java-1.x/samples/store
mvn eclipse:eclipse


2) Import the sample projects into Eclipse

- Start Eclipse
- Select File->Import : General->Existing Projects into Workspace
- Select root directory : java-1.x/samples/store
- Select File->Import : General->Existing Projects into Workspace
- Select root directory : java-1.x/samples/store-android

3) Launch the store sample application

- In eclipse project (sample-store), run the Launch.java as a Java Application

4) Launch the store android application

- In eclipse project (sample-store-android), run the project as a Android Application

You should now have your Android Fruit Store up and running, accessing the Catalog and Shopping Cart services from the regular store application we have started in step 3.

Small teams are more effective. The general agreement is that anything from 5 to 12 is the 'right' small. But of course small teams will also have 'small' throughput - relatively speaking. So if your demand is X and the throughput of a small team is X/10, you probably need 10 teams to meet that demand. But more teams also mean more effort to coordinate and align their efforts in the same direction. So, the challenge is how to harness the power of small teams and yet orchestrate multiples of them...

The initial debate is over: Any enterprise with a serious commitment to IT is migrating to the cloud. But things are not so simple. There is a complex mix of on-premises, colocated, and public-cloud deployments. In this power panel at 18th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists will look at the present state of cloud from the C-level view, and how great companies and rock star executives can use cloud computing to meet their most ambitious and disruptive business ...
The demand for organizations to expand their infrastructure to multiple IT environments like the cloud, on-premise, mobile, bring your own device (BYOD) and the Internet of Things (IoT) continues to grow. As this hybrid infrastructure increases, the challenge to monitor the security of these systems increases in volume and complexity. In his session at 18th Cloud Expo, Stephen Coty, Chief Security Evangelist at Alert Logic, will show how properly configured and managed security architecture can...
Last week I had the pleasure of speaking on a panel at Sapphire Ventures Next-Gen Tech Stack Forum in San Francisco. Obviously, I was excited to join the discussion, but as a participant the event crystallized not only where the larger software development market is relative to microservices, container technologies (like Docker), continuous integration and deployment; but also provided insight into where DevOps is heading in the coming years.
Admittedly, two years ago I was a bulk contributor to the DevOps noise with conversations rooted in the movement around culture, principles, and goals. And while all of these elements of DevOps environments are important, I’ve found that the biggest challenge now is a lack of understanding as to why DevOps is beneficial. It’s getting the wheels going, or just taking the next step. The best way to start on the road to change is to take a look at the companies that have already made great headway ...

When I talk about driving innovation with self-organizing teams, I emphasize that such self-organization includes expecting the participants to organize their own teams, give themselves their own goals, and determine for themselves how to measure their success. In contrast, the definition of skunkworks points out that members of such teams are “usually specially selected.” Good thing he added the word usually – because specially selecting such teams throws a wrench in the entire works, limiting...

Automation is a critical component of DevOps and Continuous Delivery. This morning on #c9d9 we discussed CD Automation and how you can apply Automation to accelerate release cycles, improve quality, safety and governance? What is the difference between Automation and Orchestration? Where should you begin your journey to introduce both?
While there has been much ado about interoperability, there are still no real solutions, same as last year and the year before that. The large EHR vendors who continue to dominate the market still maintain that interoperability is all but solved, still can't connect EHRs across the continuum causing frustration by providers and a disservice to patients. The ONC pays lip service to the problem, but that is about it. It is time for the healthcare industry to consider alternatives like middleware w...
