The document contains slides from a presentation on serverless architectures. It discusses several serverless patterns including building web apps and APIs with AWS Lambda, Amazon API Gateway and other services. It also covers stream processing patterns using Amazon Kinesis and analytics, real-time analytics examples, additional patterns like serverless data lakes and operations automation. The slides provide examples and best practices for implementing these serverless architectures and patterns on AWS.

Pattern 2:
Stream Processing

10. © 2018, Amazon Web Services, Inc. or its Affiliates. All rights reserved.© 2018, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Stream processing characteristics
• High ingest rate
• Near real-time processing (low latency from ingest to
process)
• Spiky traffic (lots of devices with intermittent network
connections)
• Message durability
• Message ordering

Best practices
• Tune Firehose buffer size and buffer interval
• Larger objects = fewer Lambda invocations, fewer S3 PUTs
• Enable compression to reduce storage costs
• Enable Source Record Backup for transformations
• Recover from transformation errors
• Follow Amazon Redshift Best Practices for Loading Data
• How to handle time series, sorted data

Amazon Kinesis Streams and AWS Lambda
• Number of Amazon Kinesis Streams shards corresponds to concurrent invocations
of Lambda function
• Batch size sets maximum number of records per Lambda function invocation
