DynamoDB: A fully managed NoSQL database service that provides fast and predictable performance at any scale.
Aurora: A MySQL and PostgreSQL-compatible relational database engine that combines the performance and availability of commercial databases with the simplicity and cost-effectiveness of open-source databases.
Redshift: A fast, fully managed data warehouse service.
Azure Database Offerings
SQL Database: A fully managed relational database service based on SQL Server.
Cosmos DB: A globally distributed, multi-model database service that supports various data models, including document, graph, and key-value.
Azure Database for MySQL, PostgreSQL, and MariaDB: Managed database services for open-source database engines.
Azure Synapse Analytics: A limitless analytics service that brings together data warehousing and big data analytics.
Google Cloud Database Offerings
Cloud SQL: A fully managed relational database service that supports MySQL, PostgreSQL, and SQL Server.
Cloud Spanner: A globally distributed, scalable, and strongly consistent database service.
Cloud Datastore: A NoSQL document database service.
BigQuery: A fully managed, serverless data warehouse service.
4. Pricing Models
Understanding the pricing models of each cloud provider is crucial for cost optimisation.
AWS: Offers a variety of pricing options, including pay-as-you-go, reserved instances, and spot instances. Provides a free tier for certain services.
Azure: Offers pay-as-you-go pricing, reserved instances, and hybrid benefit for using existing on-premises licenses. Also provides a free tier.
Google Cloud: Offers sustained use discounts for long-running workloads, committed use discounts, and pay-as-you-go pricing. Provides a free tier for some services.
Each provider has complex pricing structures. Tools like cloud cost calculators can help estimate expenses. Consider frequently asked questions about cloud pricing to better understand the nuances.
5. Security Features
Security is a top priority for all cloud providers. They offer a range of security features to protect data and applications.
AWS: Offers a comprehensive set of security services, including Identity and Access Management (IAM), Key Management Service (KMS), and CloudTrail. Compliant with various industry standards and regulations.
