Study Notes
- Amazon Keyspaces is a fully managed, scalable, and secure database service for Apache Cassandra applications.
- It caters to workloads needing a highly scalable NoSQL database with low-latency operations.
- It efficiently manages large data volumes across distributed systems.
- Keyspaces serves as a cloud-native alternative to self-hosted Cassandra, reducing operational overhead.
Key Features
- Keyspaces supports Cassandra Query Language (CQL), ensuring compatibility with existing Cassandra tools and data models.
- The service handles scaling, patching, and replication automatically, reducing management tasks.
- It scales elastically based on workload demands, accommodating traffic spikes and large data volumes.
- High availability is ensured through multi-Region replication.
- Data durability is maintained by storing data across multiple availability zones.
- Pricing is based on actual usage, covering read/write requests and data storage, optimizing cost for dynamic workloads.
- Being serverless, it removes the need for provisioning or managing database servers.
- It supports encryption at rest via AWS KMS, encryption in transit using TLS, and integrates with IAM.
- Virtual Private Cloud (VPC) provides network isolation, and AWS CloudTrail offers audit logs.
- It integrates with AWS Lambda, Amazon CloudWatch, AWS Glue, and AWS Data Pipeline for enhanced workflows.
Pricing
- It follows a pay-as-you-go model.
- Charges are based on the number of read and write requests, measured in request units.
- The cost depends on the number of reads (consistent or inconsistent) and writes to the database.
- Data storage is billed per GB per month.
- Snapshot costs are based on stored data volume and can be automatic or on-demand.
- Data transfer within the same AWS region is free; cross-region transfers incur additional charges.
Conclusion
- Amazon Keyspaces provides a managed NoSQL database service which simplifies Apache Cassandra workloads in the cloud.
- It offers scalability, maintains high availability, and easily integrates within the AWS ecosystem.
- The serverless nature, combined with compatibility and security make it ideal for high-volume, low-latency applications.
