AWS has recently introduced regional availability for the managed NAT Gateway service. The new capability allows developers to create a single NAT Gateway that automatically spans multiple availability zones (AZs) in a VPC, providing high availability, eliminating the need to define separate gateways and public subnets in each zone. A NAT Gateway lets instances in a private subnet access the internet or other services outside a VPC using the NAT Gateway's IP address.

Valkey was forked from Redis in April last year after the popular in-memory database - often used as a cache - moved to a less permissive license. Shifting Redis to a dual-licensed Redis Source Available License (RSALv2) and Server Side Public License (SSPLv1) prompted the Linux Foundation to fork the code from Redis 7.2.4, backed by AWS, Google, Snap, Ericsson, Oracle, and others.

A well-configured network is critical for deploying SQL Server FCI across multiple availability zones and regions in Azure, enabling seamless high availability and disaster recovery.
