RDS Proxy Flashcards
What is Amazon RDS Proxy?
Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon RDS, which allows applications to pool and share database connections to improve scalability and manage database workload.
How does RDS Proxy improve database performance?
RDS Proxy improves database performance by efficiently managing a large number of concurrent database connections, reducing the overhead on the database engine and improving application scalability.
Why is RDS Proxy beneficial for applications with fluctuating workloads?
For applications with fluctuating workloads, RDS Proxy is beneficial as it automatically scales to accommodate the changes in database connection volume, ensuring high availability and consistent performance without requiring manual intervention.
What databases are supported by RDS Proxy?
RDS Proxy supports Amazon Aurora and Amazon RDS for MySQL and PostgreSQL.
How does RDS Proxy enhance database security?
RDS Proxy enhances database security by leveraging AWS Identity and Access Management (IAM) to authenticate and authorize database access, and by providing secure data transit with SSL encryption.
Can RDS Proxy help with failover scenarios?
Yes, RDS Proxy supports automatic failover, helping to maintain database connectivity during primary database failover events, thus enhancing the resiliency of database-backed applications.
How does connection pooling work in RDS Proxy?
Connection pooling in RDS Proxy works by maintaining a pool of database connections that can be reused by different application threads or processes, thus reducing the time and resources needed to establish new connections.
What is the impact of RDS Proxy on database latency?
RDS Proxy is designed to have a minimal impact on database latency. Its connection pooling and reuse capabilities can lead to improved application response times by reducing connection overhead.
Is there any additional cost associated with using RDS Proxy?
Yes, using RDS Proxy incurs additional costs based on the compute capacity and the amount of data processed by the proxy, in addition to the standard costs associated with Amazon RDS.
How do I set up RDS Proxy with my RDS database?
Setting up RDS Proxy involves creating a proxy through the AWS Management Console or AWS CLI and configuring it to work with your RDS database instances, including setting appropriate security and network access controls.
