One does not simply Automate using Google APIs Thursday, March 7, 13 

How we build software A Customer has a nick name has a full name has a date of birth has a social security number which is sensitive can be viewed or created or changed by a customer service representative An Order belongs to a Customer has a description can be viewed or created or changed by a customer service representative An Order Line Item is audited belongs to an Order has a description has a price which is a number can be viewed or created or changed by a customer service representative Dictation + Airlift on Google App Engine Thursday, March 7, 13 

Current processes manual and paper based for recording line items for accounts receivable and accounts payable. Thursday, March 7, 13

Evolution One - Cron /accounting/receivable Process widgets sold for accounting line items every day 12:30 America/New_York /accounting/payable Process line items for widget making workers every day 03:30 America/New_York Thursday, March 7, 13 

Evolution Two - Backends • Use Backends to process long lived requests - No Request Deadlines • Higher CPU up to 4.8GHz and Memory limits - up to 1GB • Also using Spreadsheet Batch Thursday, March 7, 13 

Evolution Two - Backends • Dynamic vs Resident - Dynamic Backends become alive only on request and are turned off when idle Thursday, March 7, 13 

Evolution Two - Backends true true B8 backends.xml /accounting/receivable Process widgets sold for accounting line items every 20 minutes America/New_York accounting /accounting/payable Process line items for widget making workers every 40 minutes America/New_York accounting cron.xml Thursday, March 7, 13 

Task Queues work discretely on a unit of work Push - processes tasks based on rate configuration, auto scales Pull - allows for specific time and timeframe to run Thursday, March 7, 13

Task Queue Headers • X-AppEngine-QueueName, the name of the queue (possibly default) • X-AppEngine-TaskName, the name of the task, or a system-generated unique ID if no name was specified • X-AppEngine-TaskRetryCount, the number of times this task has been retried; for the first attempt, this value is 0. This number includes attempts where the task failed due to a lack of available instances and never reached the execution phase. • X-AppEngine-TaskExecutionCount, the number of times this task has previously failed during the execution phase. This number does not include failures due to a lack of available instances. • X-AppEngine-TaskETA, the target execution time of the task, specified in microseconds since January 1st 1970.
