    We should use the same username and password which we have provided while we launched an RDS Instance. In Secrets Manager , We create secrets with username and password fields. By doing so , The RDS proxy will be able to connect with the respective user of the Database instance.

    And then click Store a new secret Here We are going to specify the Type of Secret we are going to use. And then choose the Database Instance from the list. Secrets Manager retrieves the connection strings about the Databases by querying the Chosen database. Optionally , Add tags for the Secrets and then click Next We can optionally configure automatic rotation of Secrets. We can set rotation interval for each secrets we create.

    And Click Store. We have successfully added database and it credentials in Secrets. For this we need ARN of the secret which we created earlier.

    Click JSON , replace the existing content with the below contents. Now we have to create a Role and then attach the policy with it. To create Role , from the Left pane , Choose Roles. Ideal client connection timeout , The time period that the client connection can be idle before the proxy closes the connection. The default connection timeout is 30 minutes. For Target group configuration , Choose one RDS instance or aurora cluster to access through this proxy. If you are using only only proxy instance they set the percentage to Then for Subnets , minimum of 2 subnets required from different Availability zones.

    If you wish to enable enhanched logging for the RDS proxies , Enable it , which will be published to Cloudwatch logs. Click the proxy name which you have created. You can find the proxy endpoint there. Make a note of it , We are going to use it in the next step. The main difference is that you specify the proxy endpoint instead of the instance or cluster endpoint. Once the proxy endpoint is ready , Check whether is endpoint is reachable. Conclusion We have learnt to manage database connections using RDS proxy.

    How to fix: can’t connect to Amazon RDS DB using RDS Proxy

    After several tests and metrics, I want to share what I have learned. Increases app availability. Improves data security.

    However, when we started working with serverless architectures and relational databases Aurora MySQL , we encountered some interesting challenges: DB performance and connection management: Having simultaneous connections means our database has to use its computing resources to manage these connections and support their escalation in the event of a traffic peak.

    Failover time: When having critical applications in serverless architectures, availability will always be a priority, for this reason, we must seek an efficient cost relationship between services and availability. Security: How to handle connection string, username, and password for the database through multiple lambda functions? This transaction-level reuse is called multiplexing. Once finished, it returns to the pool.

    Pinning: In some cases, the RDS proxy is not sure if it can reuse a connection outside the session. In these cases, the session is kept on the same connection until the session ends. Failover time Failover can happen when you have a problem with the master instance, when you execute an update, or due to connectivity problems.

    During a failover, the RDS proxy continues to accept connections from the same source and automatically directs them to the new instance that will act as the master instance. Local DNS caching. Uncertainty about which DB instance is the current writer. Waiting for a query response from a former writer that became unavailable without closing connections. You can connect to the proxy using a higher version of TLS than you use in the underlying database.

    In order to connect the Llambda function to the database, everything must be done through the Secrets Manager service, where there is a secret that is configured in the Proxy. It is a script that, in two cycles, does recurrent writing tasks in the database. We ran a total of 15 tests on each of them: Failover without RDS Proxy: in this scenario, we had database unavailability of 10—12 seconds while failover. Lessons learned Whenever AWS releases a new service, I suggest waiting 3—6 months to use it in production environments.

    If you are going to implement RDS Proxy, take into account the costs and how they can impact the project. For productive environments, I definitely recommend the use of a proxy to improve security, connections, and failover.

    Make a note of itWe are going to use it in the next step. The main difference is that you specify the proxy endpoint instead of the instance or cluster endpoint. How is that going to affect your overall RDS costs? Of course, as you are likely preserving connections, you might be able to absorb the cost of the proxy itself by running a smaller instance, but that might not be always the case. Note that as per the current documentation, the Amazon RDS Proxy preview was free until the end of only.

    To recap, RDS Proxy is a new service by Amazon and still in preview but the results in term of reduced failover times are really promising. On top of providing a simpler layer to handle database connections for serverless architectures. The content in this blog is provided in good faith by members of the open source community.
