Data Center Security: DCFW Classification Data Sheet
Technology Overview and Test Metrics
A firewall is a mechanism used to protect a trusted network from an untrusted network, while allowing authorized communications to pass from one side to the other. Performance metrics, while important in any firewall, become critical in a data center deployment. Data center firewalls (DCFWs) handle multiple application traffic mixes for hundreds of thousands of users, and thus must support higher data rates. The performance versus cost trade-offs of DCFW products are based on use case and evaluated in the following areas:
TCO based on performance (TCO per Protected Mbps) – Throughput is a common metric of benchmarking products since it creates a simple comparison of how much information can be processed such as cloud computing and secure transaction but however it is not the only metric taken into consideration.
TCO based on connection rate performance (TCO per Protected CPS per Mbps) - Connections per second is a critical metric for data centers that host applications with short connection durations at high transaction rates such as ecommerce sites and high volume database transactions.
TCO based on concurrent connections performance (TCO per Protected Concurrency per Mbps) – Concurrent connections provide insight into how and where users are connected for longer durations such as SaaS based applications (Software-as-a-Service) and media streaming.
