  29. 29. 29S L I D EJ a i p u r , I n d i a S E R V E R L E S S D A Y S 2 0 1 9- [ ] - Internet of Things Serverless Python Create Ideas Lambda/Function structure for IOT Lambda Handlers Parse incoming request message based on type/context Event / Session Handlers Handle launch events and session events Response Builders Custom logic and API to generate response based on parsed input and sends back
  30. 30. 30S L I D EJ a i p u r , I n d i a S E R V E R L E S S D A Y S 2 0 1 9- [ ] - Internet of Things Serverless Python Create Ideas What can you integrate in lambdas? • REST APIs / Http Servers • Database querying scripts. • Kafka Queues • Randomized generators • Filtering and transforming data on the fly • Automated backups and everyday tasks and Reports • Log analysis on the fly
  31. 31. 31S L I D EJ a i p u r , I n d i a S E R V E R L E S S D A Y S 2 0 1 9- [ ] - Internet of Things Serverless Python Create Ideas Lambda Tips and Tricks • Lambda Functions are recycled. Subsequent invocation are redeployed & add latency. Worse if networked.
  32. 32. 32S L I D EJ a i p u r , I n d i a S E R V E R L E S S D A Y S 2 0 1 9- [ ] - Internet of Things Serverless Python Create Ideas Lambda Tips and Tricks • If you are using Node 4.*, upgrade! OpenSSL bug causes SSL connections will fail without cause intermittently, but only if you’re using DynamoDB. Just upgrade to Node 6.x • Try and Avoid Global State Usage! Containers are reused, it’s possible to stuff data into global memory and, with a good probability, it will be there in the next invocation.
  33. 33. 33S L I D EJ a i p u r , I n d i a S E R V E R L E S S D A Y S 2 0 1 9- [ ] - Internet of Things Serverless Python Create Ideas Lambda Tips and Tricks • Keep timeouts to a minimum. Most async library operations come along with long default timeout periods. NodeJs has default of 2 minutes. Alexa expects an answer in 7.5s. Keeps applications well behaved. • User friendly error logging. Make sure that you log custom metrics for tracking these “soft errors” since Lambda’s invocation error metrics won’t be relevant anymore. (Cloudwatch on AWS helps!)

Each skill has a unique Invocation Name A variable within an utterance. Variable possibilities must be defined. The spoken message is mapped to an intent which decides what code to run within your skill. A spoken phrase that maps to an intent. A skill can have many utterances.
