Access Amazon RDS across AWS accounts using AWS PrivateLink, Network Load Balancer, and Amazon RDS Proxy

Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon Relational Database Service (Amazon RDS) and Amazon Aurora that makes applications more scalable, secure, and resilient to database failures. With RDS Proxy, you can handle unpredictable surges in database traffic that might otherwise cause issues due to using all available connections or creating new connections at a fast rate. One of the main benefits of RDS Proxy is that it can improve application recovery time while efficiently and automatically handling database failovers, which is valid with both planned and unplanned failovers. For more details, see Improving application availability with Amazon RDS Proxy. For common use cases where RDS Proxy is beneficial, refer to Amazon RDS Proxy FAQs. In this post, we show how to securely and efficiently connect applications in different AWS accounts to an RDS database instance or Aurora cluster using RDS Proxy, AWS PrivateLink, and Network Load Balancer.

Upgrade Amazon DocumentDB 3.6 to 5.0 with near-zero downtime

Amazon DocumentDB (with MongoDB compatibility) is a fully managed native JSON database designed for scaling enterprise workloads. You can use the same MongoDB API 3.6, 4.0, and 5.0 application code, drivers, and tools to run, manage, and scale workloads on Amazon DocumentDB without worrying about managing the underlying infrastructure. As a document database, Amazon DocumentDB makes it simple to store, query, and index JSON data. With Amazon DocumentDB version 5.0, you can now perform a major version upgrade of your Amazon DocumentDB clusters from version 3.6 and 4.0 to 5.0 in order to unlock latest features including support for vector search, I/O-optimized storage, document compression, text search, partial index and more. In this post, we explore how to perform an upgrade with near-zero downtime from Amazon DocumentDB 3.6 to 5.0 by using an in-place major version upgrade and Amazon DocumentDB volume cloning.

Automate SQL Server discovery and assessment to accelerate migration to AWS

Adopting lift and shift or rehost migration approach can be a viable option for time-sensitive scenarios, particularly when transitioning from an on-premises data center environment. However, it’s crucial to ensure that the chosen migration strategy aligns with your organization’s overall cloud adoption strategy to realize the long-term benefits of cloud-native architectures. For many applications, a […]
