Pattern-type (Part 15): How to create a client using Python scripts for a shared service on IBM SmartCloud Application Workload Service

The example provided in the PDK is very clear. The idea is to call the shared service by adding some function in your *.py scripts.

In the PDK example, you will find a Python script call ‘action.py’ which contains all methods in order to call your shared service.

You will need only to change, the name of the shared service.

    regInfo = maestro.registry.getRegistry("sample", "1.0")        # Retrieve info on SharedService (IP) so we know where to go
    ipAddr = regInfo['ip']
    jsonResults = pcurlInvoke(ipAddr, "sample", method, sslOpts, url, str(json))       # Drive pcurl method

by

    regInfo = maestro.registry.getRegistry("poolmanager", "1.0")        # Example to call the poolmanager .
    ipAddr = regInfo['ip']
    jsonResults = pcurlInvoke(ipAddr, "poolmanager", method, sslOpts, url, str(json))       # Drive pcurl method

Pattern-type (Part 14): How to create a client using ServiceProvisioner for a shared service on IBM SmartCloud Application Workload Service

In this article, I explain how to create a simple client for the shared service created in the article Pattern-type (Part 13): How to create shared services for IBM SmartCloud Application Workload Service.
We can call APIs defined by a shared service either from an OSGI component or from python scripts. In this article I will demonstrate the OSGI component method.
We will use as base plugin, the Master-Slave plugin we developed along this education series.

Pattern-type (Part 13): How to create shared services for IBM SmartCloud Application Workload Service

Let’s imagine you would like to manage a pool of resources, each resource are not sharable and thus a pattern can request a resource at deployment time and return the resource during its deletion.
To reach that goal, you can create, what we call, a shared service. The shared service will manage the pool of resources and provide basic functionality such as ‘get a resource’, ‘return a resource’. Continue reading

How to setup Eclipse to develop Web App for IBM SmartCloud Application Service

It is very easy to setup an eclipse environment (Indigo or Juno) to develop Web Application for IBM SmartCloud Application Service.
For the time being IBM SmartCloud Application Service (Workload Service) provides WebSphere Application Server version 7.x and of course to be able to develop an application for this platform you will need the stub. The stub is provided by installing the WebSphare Application Server on your laptop which make non-sense! Why using the cloud if you have to install an application server on your laptop in order to make some development! Continue reading

Reusable assets in IBM PureApplication System and IBM SmartCloud Application Services

This article is also valid for IBM SmartCloud Application Services!

Summary:  Reusable components provide a method by which domain experts can capture their knowledge of an enterprise system into reusable components that can be easily consumed by users creating new application patterns. This article describes the use of reusable components and application templates within IBM® PureApplication™ System. Learn about processes that can be used to accelerate the development life cycle and provide consistent implementations across deployments. Continue Reading ->

How to setup your SCAS/IWD/PureApp plugin development environment?

The IWD technology is used in different IBM products such as IBM SmartCloud Application Services (SCAS) and IBM PureApplication (part of the PureSystems product line).

This technology uses patterns to deploy application and the underlying infrastructure. Pattern-types defines the rules to design patterns. SCAS out of the box provides pattern-types such as the “Web Application” or the “Java” pattern-types. Developers wrote the plugins which define the pattern-types.
