Study Notes
- Amazon Kinesis is a fully managed AWS service designed for real-time streaming data at scale.
- It facilitates the collection, processing, and real-time analysis of large data quantities such as log files, social media feeds, website clickstreams, and IoT sensor data.
Four Main Services Within Amazon Kinesis:
- Kinesis consists of four main services.
Kinesis Data Streams (KDS):
- Kinesis Data Streams is for capturing and storing real-time data streams.
- Data is organized into shards representing throughput units.
- Consumers like Kinesis clients or Lambda functions can read data from these shards.
- Use cases include collecting and analyzing website interactions, processing logs, or tracking real-time user activity.
Kinesis Data Firehose:
- Kinesis Data Firehose loads real-time streaming data into AWS services like S3, Redshift, or Elasticsearch for further analysis and storage.
- It automatically scales to manage data without manual intervention.
- Use cases include streaming data into S3 for storage, processing in Redshift for analytics, or sending to Elasticsearch for search.
Kinesis Data Analytics:
- Kinesis Data Analytics allows processing and analyzing real-time data using SQL queries.
- Streaming applications can filter, aggregate, and analyze data streams as they flow through Kinesis, without infrastructure management.
- Use cases include aggregating metrics from website user activity in real-time, such as page views or purchases, and trigger actions based on thresholds.
Kinesis Video Streams:
- Kinesis Video Streams is designed for handling video data in real-time.
- It captures, processes, and stores video from sources like security cameras, webcams, or mobile devices.
- Use cases include real-time monitoring of video streams, such as live video surveillance or streaming video data to the cloud.
Key Features:
- Real-Time Data Processing: Enables analyzing data as it is generated for immediate insights and quick action.
- Scalability: Automatically scales to handle any amount of incoming data without needing capacity provisioning or infrastructure management.
- Durability: Ensures data is stored redundantly across multiple AWS Availability Zones, offering reliability and durability.
- Integration with AWS Services: Integrates with AWS services like Lambda, S3, and Redshift.
- Flexible Data Processing: Offers stream processing with Data Streams, data ingestion with Data Firehose, or real-time analytics with Data Analytics.
Common Use Cases:
- Real-time Analytics: Analyze user behavior or system metrics in real-time.
- Log and Event Data Processing: Process application logs, sensor data, or IoT device data in real-time for monitoring or alerting.
- Data Ingestion for Big Data Processing: Ingest large volumes of streaming data into systems like Amazon S3 or Redshift.
- Real-time Video and Media Streaming: Stream video data and process or store it for analysis, security, or monitoring.
Capacity modes:
- Provisioned: You manually select the number of shards and adjust them as needed using the API.
- On demand: The system adjusts capacity based on observed throughput peaks from the last 30 days.
Key properties of kinesis data stream:
- Scalable: Automatically scales with increased data volume by adjusting the number of shards.
- Real-Time: Data is available for immediate processing with low latency.
- Configurable Retention: Data can be stored for up to 7 days duration.
- Durability: Data is replicated across multiple Availability Zones guaranteeing fault tolerance.
- Ordered: Ensures the correct sequence of records within each shard.
- Multiple Consumers: Supports simultaneous data consumption by multiple applications or services.
- Secure: Includes encryption and access control features for data security.
- Integration: Easily integrates with other AWS services for end-to-end processing.
- Producers and consumers: producer (SDK, KPL, KCL) consumer (Lambda, kinesis firehouse, kinesis data analytics)
