Cloud Development with Camel and Amazon Web Services
4 likes2,038 views
This presentation will demonstrate how to rapidly prototype and develop distributed, scalable applications with Apache Camel, its AWS Components and the AWS Java SDK. Robin Howlett is Senior Architect at Silver Chalice, a Chicago White Sox affiliated start-up, based in Boulder, CO, with a portfolio of high-value digital-based businesses in the fields of sports, media and entertainment. In 2011, he built the Advanced Media Platform, a proprietary cloud-based platform that services millions of requests per day across dozens of mobile application products, heavily utilizing the Apache Camel framework.

- 23. Activity workers are independent task processors. They can do a variety of different tasks e.g. poll, store and converts providers’ data Activity to our reference data models Workers Different workers can be responsible for each processing step, and can be combined in any way, so they are extremely scaleable The workflow engine is the coordination and orchestration system. It is capable of Workflow controlling clusters of workers, load balancing, Engine handling distributed exceptions and tracking workflow progress. Workflow workers decide the order, timing Workflow The workflow scheduler is Workflow and concurrency of tasks the Workers Scheduler responsible for when workflows activity workers should be started work on Friday, May 18, 12
- 24. AWS FLOW FRAMEWORK • Java programming framework for SWF • Translates method calls into schedule decisions; assigns tasks to workers • Long running workflows, large media processing • @Workflow and @Activities (show simple example) Friday, May 18, 12
