A Decentralized Cloud Firewall Framework with Resources Provisioning Cost Optimization

Abstract

A new flexible method for supplying more computer power in a shared media is called cloud computing. It offers a distributed paradigm based on self-evaluation methods to increase the system's processing power with less managerial worries. Clients, applications, platforms, servers, and infrastructures make up its components. This computing architecture provides end users with calculation skills as a computed service from the aforementioned components.  Security management will lose importance when more devices and their integration become available. One needs to manage data, system, and confidentiality problems carefully since cloud users are growing daily.  Therefore, in order to address protected access and integrity concerns in a cloud environment, new security firewall services must be deployed in addition to the current system. Numerous network-related issues, including load balancing, scheduling, traffic divergence, filtering, regulating the rate of arrival, instance management, and attack detection, make it difficult to implement firewalls for cloud computing.  A centralised cloud firewall makes it very difficult to predict the response time. Consequently, a new line of work has been established for actually implementing the new firewall techniques for the cloud. In order to reduce the cost of ownership and operation, it also strives to achieve resource optimization-based provisions and guidelines.
