Amazon RDS Extended Support for MySQL 5.7 & PostgreSQL 11
Your MySQL 5.7 and PostgreSQL 11 database instances on Amazon Aurora and Amazon RDS will automatically enroll in Amazon RDS Extended Support commencing February 29, 2024.
This will prevent unanticipated downtime and compatibility concerns from automated major version upgrades. You have more control over when to upgrade your major database.
RDS Extended Support may cost more due to automated enrollment. Upgrade your database before RDS Extended Support to prevent these expenses.
Describe Amazon RDS Extended Support
Amazon RDS Extended Support, announced in September 2023, lets you run your database on a major engine version on Amazon Aurora or Amazon RDS after its end of standard support date for a fee.
The MySQL and PostgreSQL open source communities identify CVEs, generate patches, and resolve bugs until community end of life (EoL). Until the database major version is retired, the communities release a quarterly minor version with security and bug updates. CVE patches and bug fixes are no longer available after the community end of life date, making such engines unsupported. As of October and November 2023, the communities no longer support MySQL 5.7 and PostgreSQL 11. AWS appreciate community support of these major versions and a transparent transition process and schedule to the latest major version.
Amazon Aurora and RDS engineer crucial CVE patches and bug fixes for up to three years after a major version’s community EoL with RDS Extended Support. Amazon Aurora and RDS will find engine CVEs and problems, develop patches, and deploy them swiftly for three years. Under RDS Extended Support, AWS will continue to support an engine’s major version after the open source community ends support, protecting your applications from severe security risks and unresolved problems.
You may ask why we charge for RDS Extended Support instead of including it in RDS. AWS must invest developer resources in crucial CVE patches and bug fixes to preserve community EoL engine security and functionality. Because of this, RDS Extended Support only charges clients that need the flexibility to stay on a version past its EoL.
If your applications depend on a specific MySQL or PostgreSQL major version for plug-in compatibility or bespoke functionality, RDS Extended Support may help you satisfy your business objectives. If you’re running on-premises database servers or self-managed Amazon Elastic Compute Cloud (Amazon EC2) instances, you can migrate to Amazon Aurora MySQL-Compatible Edition, Amazon Aurora PostgreSQL-Compatible Edition, Amazon RDS for MySQL, and Amazon RDS for PostgreSQL beyond the community EoL date and use them with RDS Extended Support in a managed service. RDS Extended Support lets you phase a large database transfer to ensure a smooth transition without straining IT resources.
RDS Extended Support will be provided in 2024 for RDS for MySQL 5.7, PostgreSQL 11, Aurora MySQL-compatible 2, and Aurora PostgreSQL 11. A supported MySQL major version on Amazon RDS and Amazon Aurora major versions in the AWS documentation lists all future supported versions.
Why are all databases automatically enrolled in Amazon RDS Extended Support?
AWS were told you RDS Extended Support would deliver opt-in APIs and console functionality in December 2023. AWS announced that if you did not opt your database into RDS Extended Support, it would automatically update to a newer engine version on March 1, 2024. You would be upgraded from Aurora MySQL 2 or RDS for MySQL 5.7 to Aurora MySQL 3 or RDS for MySQL 8.0, and from Aurora PostgreSQL 11 to 15 and RDS for 15.
However, several users complained that these automated upgrades may damage their applications and cause other unpredictable behavior between major community DB engine releases. If applications are not ready for MySQL 8.0 or PostgreSQL 15, an unplanned major version upgrade could cause compatibility issues or downtime.
Automatic enrollment in RDS Extended Support allows you more time and control to organize, schedule, and test database upgrades on your own timeline while receiving essential security and bug fixes from AWS.
Upgrade before RDS standard support ends to prevent automatic enrollment in RDS Extended Support and associated fees.
Upgrade your database to avoid RDS Extended Support fees
RDS Extended Support helps you schedule your upgrade, but staying with previous versions means missing out on the greatest price-performance for your database workload and paying more for support.
Global Database, Amazon RDS Proxy, Performance Insights, Parallel Query, and Serverless v2 deployments are supported in Aurora MySQL 8.0, also known as Aurora MySQL 3. RDS for MySQL 8.0 supports AWS Graviton2 and Graviton3-based instances, Multi-AZ cluster deployments, and Optimized Reads and Writes for up to three times better performance than MySQL 5.7.
Aurora PostgreSQL 15 Aurora I/O Optimized, Aurora Serverless v2, Babelfish for Aurora PostgreSQL, pgvector extension, TLE, AWS Graviton3-based instances, and community additions are supported by PostgreSQL. RDS for PostgreSQL 15 adds Multi-AZ DB cluster deployments, RDS Optimized Reads, HypoPG extension, pgvector extension, TLEs, and AWS Graviton3-based instances.
Major version upgrades may change databases incompatible with existing apps. To upgrade to the major version, manually edit your database. Any major version upgrade should be tested on non-production instances before being applied to production to verify application compatibility. The AWS documentation describes an in-place upgrade from MySQL 5.7 to 8.0, including incompatibilities, Aurora MySQL in-place major version upgrade, and RDS for MySQL upgrades. Use pgupgrade to upgrade PostgreSQL 11 to 15 in-places.
AWS advocate Fully Managed Blue/Green Deployments in Amazon Aurora and Amazon RDS to reduce upgrade downtime. Amazon RDS Blue/Green Deployments can establish a synchronized, fully controlled staging environment that mimics production in a few clicks. A parallel green environment with upper-version clones of your production databases lower-version is needed. Traffic might transition to the green environment after validation. Blue environment can be discontinued. Blue/Green Deployments reduce downtime best in most cases, except with Amazon Aurora and Amazon RDS.
Currently accessible
Amazon RDS Extended Support is now available for clients utilizing MySQL 5.7, PostgreSQL 11, and higher versions in AWS Regions, including AWS GovCloud (US), beyond the 2024 standard support expiration. You can upgrade your databases and obtain 3 years of RDS Extended Support without opting in.

Using the ETL Tool in AWS Database Migration
AWS (Amazon Web Service) is a cloud-based platform providing infrastructure, platform, and packaged software as a service. However, the most critical service of Amazon Web Service Database Migration Service (AWS DMS) is migration of data between relational databases, data warehouses, and NoSQL databases for which ETL in AWS is the most optimized tool.
To understand why ETL in AWS is preferred for migrating databases, one should know how the ETL tool works. ETL is short for Extract, Transform, Load. Through these three steps data is combined from several sources into a centralized data warehouse. In the ETL in AWS process, data is extracted from a source, transformed into a format that matches the structure of the target database, and then loaded into a data warehouse or a storage repository.
The Benefits of ETL in AWS
There are several benefits of ETL in AWS for database migration.
· Organizations need not install and configure additional drivers and applications or change the structure of the source database when migration is done with ETL in AWS. The process is initiated directly through the AWS Management Console whereby any change or update is replicated to the target database through its Change Data Capture (CDC) feature.
· Changes that occur in the source database are updated at regular intervals to the target database by ETL in AWS. However, for this to happen, the source and the target databases should always be kept in sync. Most importantly, the migration process can take place even when the source database is fully functional. Hence, there is no system shutdown, a big help for large data-driven enterprises where any downtime upsets operating schedules.
· Most common and popular databases in use today are supported by AWS. Hence, ETL in AWS can handle any migration activity regardless of the structure of the databases. These include both homogeneous and heterogeneous migration. In the first, the database engines, data structure, data type and code, and the schema structures of the source and the target databases are similar while in the second case, each is different from the other.
· ETL in AWS is also widely-used for migrating on-premises databases to Amazon RDS or Amazon EC2, Aurora, and databases running on EC2 to RDS or vice versa. Apart from these possibilities, database migration can be done between SQL, text-based data, and NoSQL with DMS AWS also.
High-Performing AWS Glue
There are various tools for ETL in AWS, but the most high-performing one is AWS Glue. It has a fully managed ETL platform that eases data processing for analysis. The tool is very user-friendly and can be set up and running with only a few clicks on the AWS Management Console. The advantage here is that AWS Glue discovers data automatically and stores the connected metadata in the AWS Glue Data Catalog. Later, the data can be searched and queried instantly.

AWS CDK database queries in PostgreSQL and MySQL
With support for the AWS Cloud Development Kit (AWS CDK), AWS are now able to connect to and query your current MySQL and PostgreSQL databases. This is a new feature that allows you to construct a secure, real-time GraphQL API for your relational database, either inside or outside of Amazon Web Services (AWS). With merely your database endpoint and login credentials, you can now construct the full API for all relational database operations. You can use a command to apply the most recent modifications to the table schema whenever your database schema changes.
With the release of AWS Amplify GraphQL Transformer version 2, which was announced in 2021, developers can now create GraphQL-based app backends that are more feature-rich, adaptable, and extensible with little to no prior cloud experience. In order to create extensible pipeline resolvers that can route GraphQL API requests, apply business logic like authorization, and interact with the underlying data source like Amazon DynamoDB, this new GraphQL Transformer was completely redesigned.
But in addition to Amazon DynamoDB, users also desired to leverage relational database sources for their GraphQL APIs, including their Amazon RDS or Amazon Aurora databases. Amplify GraphQL APIs now support @model types for relational and DynamoDB data sources. Data from relational databases is produced into a different file called schema.sql.graphql. You may still build and maintain DynamoDB-backed types with standard schema.graphql files.
Upon receiving any MySQL or PostgreSQL database information, whether it is accessible publicly online or through a virtual private cloud (VPC), AWS Amplify will automatically produce a modifiable GraphQL API that can be used to securely connect to your database tables and expose CRUD (create, read, update, or delete) queries and mutations. To make your data models more frontend-friendly, you may also rename them. For instance, a database table with the name “todos” (plural, lowercase) may be accessible to the client as “ToDo” (single, PascalCase).
Any of the current Amplify GraphQL authorization rules can be added to your API with only one line of code, enabling the smooth development of use cases like owner-based authorization and public read-only patterns. Secure real-time subscriptions are accessible right out of the box because the produced API is based on AWS AppSync’s GraphQL capabilities. With a few lines of code, you can subscribe to any CRUD event from any data model.
Starting up the MySQL database in the AWS CDK
The AWS CDK gives you the significant expressive capability of a programming language to create dependable, scalable, and affordable cloud applications. Install the AWS CDK on your local computer to begin.
To print the AWS CDK version number and confirm that the installation is correct, use the following command.
Next, make your app’s new directory:
Use the cdk init command to set up a CDK application.
Add the GraphQL API construct from Amplify to the newly created CDK project.
Launch your CDK project’s primary stack file, which is often found in lib/<your-project-name>-stack.ts. Add the following imports to the top of the file:
Run the following SQL query on your MySQL database to create a GraphQL schema for a new relational database API.
$ cdk –version
Make sure the results are written to a.csv file with column headers included, and change <database-name> to the name of your schema, database, or both.
Run the following command, substituting the path to the.csv file prepared in the previous step for <path-schema.csv>.
$ npx @aws-amplify/cli api generate-schema \
–sql-schema <path-to-schema.csv> \
–engine-type mysql –out lib/schema.sql.graphql
To view the imported data model from your MySQL database schema, open the schema.sql.graphql file.
If you haven’t already, establish a parameter for your database’s connection information, including hostname/url, database name, port, username, and password, in the AWS Systems Manager console’s Parameter Store. To properly connect to your database and run GraphQL queries or modifications against it, Amplify will need these in the following step.
To define a new GraphQL API, add the following code to the main stack class. Put the parameter paths that were made in the previous step in lieu of the dbConnectionConfg options.
This setting assumes that you can access your database online. Additionally, on all models, the sandbox mode is enabled to permit public access, and the default authorization mode is set to Api Key for AWS AppSync. You can use this to test your API before implementing more detailed authorization restrictions.
Lastly, launch your GraphQL API on the Amazon Cloud
Select the Queries menu along with your project. The newly developed GraphQL APIs, like getMeals to retrieve a single item or listRestaurants to list all products, are compatible with your MySQL database tables.
like instance, a new GraphQL query appears when you pick objects that have fields like address, city, name, phone number, and so on. You may view the query results from your MySQL database by selecting the Run button.
You get identical results when you run a query on your MySQL database.
Currently accessible
Any MySQL and PostgreSQL databases hosted anywhere within an Amazon VPC or even outside of the AWS Cloud are now compatible with the relational database support for AWS Amplify.
