As mentioned above RDS supports several open sources and licensed database engines with highly flexible scalability and performance options. What is Relational Database Service (RDS)? Most of the differences can be addressed with refactoring however, some such as lack of autonomous transactions may require a moderate development effort to handle in PostgreSQL. PostgreSQL offers a high degree of data structure compatibility with Oracle. While very valuable in many use-cases, MySQL and MariaDB do not provide many capabilities available in Oracle and PostgreSQL. MySQL, and by extension MariaDB which is a fork of the MySQL source, is a light-weight data engine focused on high-performance of simple structures. PostgreSQL is an open-source relational database designed to be highly extensible and compliant. Oracle and other RDBMSs focus on ACID (atomicity, consistency, isolation, and durability) compliance No-SQL is focused on performance at the expense of cross-transaction consistency and data normalization.Ĭonverting the Oracle database to one of the three open-source data engines available in RDS (PostgreSQL, MySQL, and MariaDB) provides freedom from licensing cost, the ability to scale to usage, leveraging the benefits of database-as-a-service (DBaaS) while managing the data in a relational fashion similar to Oracle.
POSTGRESQL VS ORACLE LICENSE
Neither a custom-built EC2 nor an Oracle RDS saves any Oracle license costs, further, the Oracle CPU based licensing will prevent the system from taking advantage of AWS’s scaling capabilities.Ĭonverting an Oracle database to a No-SQL is highly dependent on how the current database is being used. When migrating an existing Oracle database to AWS there are several options available: host the database on a custom configured EC2, transfer the data to an Oracle RDS, or convert the database to be migrated to a different AWS data service. Before making your decision, look into PostgreSQL solutions, particularly Amazon Web Service (AWS) PostgreSQL Relational Database Service (RDS) and Aurora PostgreSQL RDS. Often relational database conversions look no further than No-SQL solutions or various flavors of MySQL. Similarly, many are reevaluating the benefit of the high cost of licensed software, notably Oracle relational database management system (RDBMS).
Many corporations are undergoing migrations from on-premises IT infrastructure to cloud-based platforms.
