Embodiment

[0045] Such as figure 1As shown, cloud data centers usually host a large number of heterogeneous services, such as e-commerce services, web services, video and audio services, and so on. Often these commercial applications have different protection requirements. On the other hand, for a particular service, it is highly likely that the hosting server has similar protection needs. Therefore, the present invention divides services at the application layer. Such as figure 1 As shown, for each type of service, a firewall is installed between the Internet and the hosting server. For a certain type of service, the present invention can set up a firewall for some or each hosting server according to the difference in economic cost. Assuming that there are N servers in the cloud data center, among which there are m hosting e-commerce services. Aggregate into k classes according to the following three strategies (n 1 , n 2 ,...,n i ,...,n k ). a) Aggregate all servers into a sin...

Abstract

The invention discloses a cost-minimized firewall setting method in a cloud computing platform, which divides cloud servers into clusters, thereby deploying firewalls for the cloud computing platform; and divides the servers into groups according to the different application layers of the cloud services provided by the servers , each type of application corresponds to a group, if a server provides multiple services, select the main service as the criterion for grouping; for each cloud service, with the constraint of cost minimization, the managed server follows one of the following three strategies Aggregation into clusters: strategy a, aggregate all managed servers into a single cluster; strategy b, aggregate all managed servers into multiple clusters, the number of which is smaller than the number of servers; strategy c, treat each managed server as a cluster; Each type of cloud service establishes a separate firewall. Given a certain type of service, the present invention shows how to achieve more economical cost expenditure through clustering of hosting servers.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for setting a firewall with minimum cost in a cloud computing platform. Background technique [0002] The development and acceptance of cloud computing is increasing day by day, and it is an important infrastructure for deploying software and services in the future. Cloud service providers provide users with on-demand and elastic services, reducing capital expenditures and operating costs. [0003] Although cloud computing has many advantages, since data and business are outsourced to a third party, there are also serious security and privacy issues in the cloud. In "Determinating timing channels in compute clouds", Aviram et al. proposed a provider-enforced decision execution method to control time slice channels between VMs to avoid cross-VM attacks. In "A new form of DoS attack in a cloud and its avoidance mechanism," Liu et al. proposed a new DoS attack method th...
