Introduction to asav9-22-1-6.qcow2 Software
This QCOW2 virtual machine template (4.7GB) enables deployment of Cisco’s ASA Software 9.22(1.6) in modern cloud environments, featuring native integration with AWS Gateway Load Balancer (GWLB) dual-arm architectures. Released on March 25, 2025, it delivers enterprise-grade firewall capabilities for containerized workloads while supporting dynamic scaling from 2 vCPU/4GB RAM to 64 vCPU/256GB RAM configurations.
Designed for hybrid cloud deployments, this version introduces Kubernetes-native ASAv container (ASAc) support and automated security policy synchronization across multi-VPC AWS environments. The package includes preconfigured security contexts optimized for SD-WAN edge deployments and supports 500,000 concurrent connections in baseline configurations.
