can act at the speed of the mission. SmartEdge makes this possible at scale with an extensible platform utilizing open architecture prin- ciples and open source technologies.” At-a-Glance As a premier (SUSE RGS, formerly Rancher Federal), the Booz Allen team is underpinning its smart, tactical edge platform with K3s, the fully certified CNCF (Cloud Native Computing Foundation) Kubernetes offering. K3s infrastructure, Smart- Edge is a completely hardware-agnostic and heterogeneous solution. It was devel- oped in recognition of the diverse range of hardware in the field—a project might run in AWS, Azure

storage community since 2015. Chair of Kubernetes VMware SIG. GitHub: @cantbewong Application Platform Architect VMware Supports enterprises with architectural guidance, and works closely with VMware respecting resource access and availability concerns. When Kubernetes runs on vSphere, the hypervisor platform also supports an underlying tier of high availability and automated placement options, for both failure, the virtual machines on a failed host are restarted on alternate hosts. When running on hardware that supports health reporting, Pro-active failure avoidance can also be engaged. Example loss
