A SCAFFOLD for PERFORMANCE ENHANCEMENT in MULTITENANT'S APPLICATIONS for GEOGRAPHICAL DATA CENTRES in PRIVATE CLOUD

The aptitude to balance a web application or website is coupled directly to understanding where the resource constraints lie and what force the addition of various possessions 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 for Multi Tenant's Applications for Data Centres in a Private Cloud. When you start adding new hardware/update existing hardware in a web cloud, the complexity starts increasing which affects performance and hence security also for Multi Tenant's Applications. While priced cloud computing services save pains to maintain the computational environment, there are several drawbacks such as visual projection of virtual machines, possibility to share one physical machine with several virtual machines, and indeterminacy of topological allocation of their own virtual machines. Multi-tenancy is one of key characteristics of the service oriented computing especially for Software as a Service (SaaS) to power economy of scale to drive down total cost of ownership for both service consumer and provider. This paper aims to study the technologies to build a cost-effective, secure and scalable multi-tenant infrastructure and how to improve the security and enhance its performance for Multi Tenant's Applications for Data Centres in a Private Cloud. This paper also identifies the potential performance bottlenecks, summarizes corresponding optimization approaches and best implementation practices for different multi-tenant business usage models for Data Centres in a Private Cloud.
