Amazon Data Firehose

LOW

Amazon Kinesis Data Firehose is an AWS service that enables you to deliver streaming data to various destinations directly, without needing to write applications or manage resources. It can capture, transform, and load streaming data into analytics stores and services.

Learning Objectives

Understand the core purpose and managed nature of Kinesis Data Firehose.
Identify the various AWS services and destinations Kinesis Data Firehose can deliver data to.
Comprehend the data transformation, buffering, and encryption capabilities of Kinesis Data Firehose.

Kinesis Data Firehose Overview

Kinesis Data Firehose is a fully managed service designed to simplify the delivery of streaming data to various destinations.

Kinesis Data Firehose allows you to deliver your streaming data to a number of different destinations directly. There is no need for you to write consumer applications to do that for you or to manage the resources that are needed for that; you can simply set up a data firehose and it will direct that data through to that destination for you.

Key Features and Capabilities

Kinesis Data Firehose offers several features to manage and deliver streaming data efficiently.

A breakdown of Kinesis Data Firehose's primary capabilities:

Destinations

Kinesis Data Firehose supports delivery of streaming data to various AWS services directly. These include Amazon S3, Amazon Redshift, Amazon Elasticsearch Service, and Splunk. It can also serve as an input stream or an output stream for Kinesis Data Analytics applications.

Data Transformation

Data can be transformed before it's delivered to its destination. This transformation is achieved by using AWS Lambda code that you supply.

Source Data Backup with Transformation

If you choose to apply a data transformation using Lambda, Kinesis Data Firehose also allows you to backup the original source data. This backup is always sent to an Amazon S3 bucket, even if the transformed data is sent to a different service like Redshift or Elasticsearch.

Data Buffering

The incoming stream of data will be buffered before delivery to the destination. This buffering can be defined either by the size of the buffer in megabytes or by the buffer interval in seconds.

Server-Side Encryption

Kinesis Data Firehose supports server-side encryption for the data being streamed.

Integration with Kinesis Data Analytics

Kinesis Data Firehose plays a role in Kinesis Data Analytics workflows as both a potential source and a destination for processed data.

Streaming inputs for an Amazon Kinesis Data Analytics application can come from a Kinesis Data Firehose delivery stream.

Kinesis Data Analytics applications, after processing data with SQL statements, can deliver their output to a Kinesis Data Firehose delivery stream. This stream then directs the processed data to final destinations such as Amazon S3, Redshift, or Elasticsearch.

Glossary

Kinesis Data Firehose: An AWS service that allows you to capture, transform, and load streaming data into various destinations directly, such as Amazon S3, Redshift, Elasticsearch, and Splunk, without needing to manage infrastructure.

Buffer Size: A configuration parameter in Kinesis Data Firehose that defines the amount of incoming streaming data (in MBs) to accumulate before delivery.

Buffer Interval: A configuration parameter in Kinesis Data Firehose that defines the time duration (in seconds) to accumulate incoming streaming data before delivery.

Key Takeaways

Kinesis Data Firehose is a fully managed service for delivering streaming data to various destinations, simplifying real-time data ingestion.
It supports transformations using AWS Lambda and can automatically back up original source data to S3 when transformations are applied.
Firehose's buffering and server-side encryption capabilities enhance data delivery and security, and it integrates seamlessly with Kinesis Data Analytics for comprehensive stream processing.
