Streaming Data Processing with
Amazon Kinesis and AWS Lambda
Amazon Kinesis: A managed service for
streaming data ingestion and processing

AWS Lambda: A compute service that runs
your code in response to events
Lambda functions: Stateless, event-driven code execution
Triggered by events:
• Put to an Amazon S3 bucket
• Record in an Amazon Kinesis stream
• Direct sync and async invocations
Makes it easy to
• Build back-end services that perform at scale
• Perform data-driven auditing, analysis, and notification
High performance at any scale;
Cost-effective and efficient
No Infrastructure to manage
Pay only for what you use: Lambda
automatically matches capacity to
your request rate. Purchase
compute in 100ms increments.
Bring Your Own Code
“Productivity focused compute platform to build powerful, dynamic,
modular applications in the cloud”
Run code in a choice of standard
languages. Use threads, processes,
files, and shell scripts normally.
Focus on business logic, not
infrastructure. You upload code; AWS
Lambda handles everything else.

Things to remember when creating a Kinesis
stream
• Streams are made of Shards
• Each Shard ingests data up to 1MB/sec
• Each Shard emits data up to 2MB/sec
• All data is stored for 24 hours, Replay data inside of 24hr window
• A Partition Key is supplied by producer and used to distribute the PUTs across Shards
• A unique Sequence # is returned to the Producer upon a successful PUT call
Attaching a Lambda function to a Kinesis stream
• Shards: One Lambda function concurrently invoked per Kinesis shard
• Increasing shards will cause more Lambda functions invoked concurrently
• Each individual shard follows ordered processing

Performance tuning Kinesis as an event source
• Batch size: Number of records that AWS
Lambda will retrieve from Kinesis at the
time of invoking your function
• Increasing batch size will cause fewer
Lambda function invocations with more
data processed per function
• Starting Position: The position in the
stream where Lambda starts reading
• Set to “Trim Horizon” for ordered
processing (FIFO)
• Set to “Latest” for reading most recent
data (LIFO)
Best practices for creating Lambda functions
• Memory: CPU and disk proportional to the memory configured
• Increasing memory makes your code execute faster (if CPU bound)
• Increasing memory allows for larger record sizes processed
• Timeout: Increasing timeout allows for longer functions, but more wait in case of errors
• Retries: For Kinesis, Lambda has unlimited retries (until data expires)
• Permission model: Lambda pulls data from Kinesis, so no invocation role needed, only
execution role
Monitoring and Debugging Lambda functions
• Monitoring: available in Amazon CloudWatch Metrics
• Invocation count
• Duration
• Error count
• Throttle count
• Debugging: available in Amazon CloudWatch Logs
• All Metrics
• Custom logs
• RAM consumed
• Search for log events

“I want to apply custom logic to
process data being uploaded through
my Kinesis stream”.
• Client activity tracking
• Metrics generation
• Data cleansing
• Log filtering
• Indexing and searching
• Log routing
• Live alarms and notifications
Three Next Steps
1. Create your first Kinesis stream. You can configure hundreds of thousands of data producers to continuously put data into an Amazon Kinesis stream. For example, data from website clickstreams, application logs, and social media feeds.
2. Create and test your first Lambda function. With AWS Lambda, there are no new languages, tools, or frameworks to learn. You can use any third party library, even native ones. And the first 1M requests each month are on us!
3. Use AWS Lambda to process Amazon Kinesis streams … no infrastructure to manage, and setup real-time analytics in minutes!
