Today, AWS announces Systems Manager Explorer, an operations dashboard providing you with an at-a-glance graphical view of relevant operations data, such as EC2 instance summaries and their patch compliance. With Explorer, you can view your operations data across your AWS accounts and Regions to see where attention, investigation, and remediation may be required.
