A Framework for Enhancing Security and Performance in Multi-Tenant Applications
The ability to scale a web application or website is tied directly to understanding where the resource constraints lie and what impact the addition of various resources has on the application. Unfortunately, architects more often than not assume that simply adding another server into the mix can fix any performance problem and security issues. When one start adding new hardware/update existing hardware in a web cloud, the complexity starts increasing which affects performance and hence security. While priced cloud computing services save pains to maintain the computational environment, there are several drawbacks such as overhead of virtual machines, possibility to share one physical machine with several virtual machines, and indeterminacy of topological allocation of their own virtual machines.
