Pattern-type (Part 9): Add the capability to Tweak a virtual application instance.
In this previous article ‘Pattern-type (Part 6): How to add operation with SmartCloud Application Services‘, I explained how to add operation on a pattern-type. Operations provide you the ability to take actions on a deployed pattern/virtual application. These actions can be setting parameters and take actions based on these parameters by launching a specified script and this is done by creating an operation.json file in the appmodel.

Pattern-type (Part 8): How to extend an existing pattern-type with SmartCloud Application Services
One of my customer asked me the following question:
“I have my own logging event system and I would like that all log files information of the WebSphere Enterprise Application environment are copied to my logging event system. I don’t want to recreate the full WebApp pattern-type just to add a new functionality. So, how can I leverage the existing WebApp pattern-type and add in it just the functionality I need?” Continue reading
Pattern-type (Part 7): Scaling in/out based on OS metrics with SmartCloud Application Services
In my previous articles Pattern-type (Part 5): Scaling in/out based on your own monitoring collector with SmartCloud Application Services I explained how to Scale in/out using your own monitoring collect (ie: counting files in a directory). In noticed in the documentation (IWD Infocenter) at the end of the page a mention of a ‘CPU’ category and ‘Used’ metrics. This let me think we can re-use some embedded OS metrics in a scaling policy and I will show here how to do it. Continue reading
Pattern-type (Part 6): How to add operation with SmartCloud Application Services
When you define a role in a pattern type, you can associate to this role a number of operations you would like to launch once the pattern is deployed. These operations will be available from the ‘Manage’ panel under the operation tab. Continue reading
Did you know? An Eclipse Plugin exists for developing IWD/SCAS/PureApp pattern-type.
In the new PDK (version 1.0.3) there is a plugin that allows you to create new structure for plugin, OSGI Component, Node parts, parts and and roles… Continue reading
Pattern-type (Part 5): Scaling in/out based on your own monitoring collector with SmartCloud Application Services
From the Pattern-type (Part 4): Adding your own monitoring collector to a pattern-type with SmartCloud Application Services, we learned how to add a collector to a pattern-type in order to monitor the deployed services. It was a simple collector counting the number of files in a directory. What I propose in this article is to explain how to leverage this collector to add scaling in/out rules based on the metrics provided by this collector. Continue reading
Did you know? SmartCloud Application Services is now in pilot phase
Join the SCAS pilot: IBM SmartCloud Application Services
Pattern-type (Part 4): Adding your own monitoring collector to a pattern-type with SmartCloud Application Services
In the previous articles, I explained own to creates pattern-type for a single server, a master-slave and also how to add static scalability to a pattern-type. Now, if we want to have a dynamic scalability, a scalability which react on a monitoring feature, we have to be able to collect information from the server and this exactly what I will explain in this article. Continue reading
Pattern-type (Part 3): Adding Static scalability to a pattern-type with SmartCloud Application Services
In our ongoing journey on the pattern-type elaboration on the SmartCloud Application Services, I explained how to create a simple pattern-type, how to create a master-slave pattern-type, now I will show how to add a static scalability in the master-slave pattern-type. Of Course, this functionality also existing on the PureApplications and IWD. Continue reading
