Comparison Of Different Firewalls Performance In A Virtual For Cloud Data Center

Abstract

Every data centre, whether virtual or physical, relies on its network, and the firewall is an essential part of that network for safe communication. Data centre connection can be protected by a variety of firewall types, including software firewalls, physical firewalls, virtual appliance firewalls, and kernel-integrated firewalls. There are several factors to consider when selecting a firewall, especially in a virtualized data centre, where each firewall works differently in different situations. Virtualized data centres are intended to yield lower budgets, efficient management extensibility, better utilization of available resources, scalability, and energy resilience, among several other advantages. Virtualized data centres are the topic of this study, which examines the application of firewalls. The performance of various types of firewalls, such as software firewalls, physical firewalls, virtual appliance firewalls, and kernel-integrated firewalls, is being analysed. Virtual data centre firewall implementation and performance comparisons explain how to design and which firewall type provides the best performance. In all conditions, it was shown that kernel-integrated firewalls worked properly. Virtual machine IP addresses and networks can vary, and the kernel-based firewall can dynamically update its rules to keep pace with such changes. With its distributed firewall functionality, virtual machines can travel across hypervisors with no disruption to their security settings, if their policies remain the same. A kernel-based, distributed firewall is the best way to protect against viruses.
