Amazon Aurora: A Deep Dive into Its Functionality and Operational Mechanisms

What is Amazon Aurora

Amazon Aurora, known simply as Aurora, stands out as a fully managed relational database engine compatible with both MySQL and PostgreSQL. Familiar with the blend of speed and reliability from high-end commercial databases and the simplicity and cost-effectiveness of open-source databases provided by MySQL and PostgreSQL, Aurora seamlessly integrates with existing code, tools, and applications designed for these databases. Notably, Aurora boasts the potential to achieve up to five times the throughput of MySQL and up to three times the throughput of PostgreSQL in specific workloads, all without necessitating modifications to the majority of existing applications.

Aurora’s exceptional performance is attributed to its high-performance storage subsystem. Specifically tailored MySQL- and PostgreSQL-compatible database engines take full advantage of a rapid distributed storage system, with the underlying storage expanding automatically as demand increases. An Aurora cluster volume has the capacity to scale up to an impressive maximum size of 128 tebibytes (TiB). Simplifying what is often a complex aspect of database configuration and administration, Aurora streamlines and standardizes database clustering and replication, addressing challenges commonly associated with these processes.

Worth noting is that Aurora operates as part of Amazon Relational Database Service (Amazon RDS), a managed database…
