Amazon EC2 now offers Global View on the console to view all resources across regions together

You can now view your AWS resources such as Instances, VPCs, Subnets, Security Groups, Volumes across AWS Regions. Previously, finding specific resources, monitoring for their status or taking inventory in the console was manual and time consuming. You had to know which region a particular instance resided in, or had to manually switch across multiple different regions to look for it. Global View provides visibility to all your resources in a single pane of glass across AWS regions. It helps monitor resource counts, notice abnormalities sooner rather than later, and find stray resources.
