OVERVIEW
What is Cloud Computing?
“Cloud computing is the delivery of computing as a service rather than a product, where by
shared resources, software, and information are provided to computers and other
devices as a utility over a network”
IBM WebSphere Cast Iron Cloud Integration?
“WebSphere Cast Iron cloud integration
projects enables companies to rapidly
connect their hybrid world of public clouds,
private clouds and on-premise applications”.
Goal is to make it easier for customers to move
from legacy systems to hybrid cloud model.

Best Practices
Error Handling
 Use Try Activity to catch and handle exceptions
 Check status in response messages for other errors
 Use the Log Message, Send Email and Invoke Web Service activities to notify users of errors
 Write a generic error handling orchestration and deploy as a Web service
Monitoring
 Use a custom job key for every orchestration for better tracking
 Manage the number of job logs retained
 Set notifications to monitor system resources
Performance
 Filter data at the source or as soon as possible in the orchestration
 Use XPath predicates to filter data before looping through it
 Reduce the number of activities, combine mappings into one activity if possible
 Use lowest logging level in production
 Manage number of concurrent jobs

Best Practices (Contd)
Maintainability
 Split large orchestrations into reusable sub orchestrations
 Use configuration properties so the orchestration behavior can be changed from the WMC without
modifying the project e.g. endpoint username, password, server, URI
 Use XSLT for complex mappings
 Remove unused variables
 Use a source code control system to give you a project change history and back up
Naming Conventions
 Rename all orchestrations, endpoints, variables and activities to more descriptive names
 Limit activity names to 30 characters (WMC won't display more than that)
 Choose naming standards and be consistent e.g. Lowercase for variables, Uppercase for orchestrations
and endpoints
 Configuration properties are listed in alphabetical order in the WMC so put the endpoint at the start of the
name to group them together e.g. FTPPassword, FTPPort, FTPServer, FTPUsername,
SalesforcePassword, SalesforceURI, SalesforceUsername
 Do not abbreviate names e.g. SalesforcePassword is easier to understand than SFPwd
