Cloud Services  There are 5 commonly used categories in a spectrum of cloud offerings Platform-as-a-service (PaaS) -Provision H/W, OS, Framework, Database Software-as-a-service (SaaS) - Provision H/W, OS, Special purpose S/W Infrastructure-as-a-service (IaaS) - Provision H/W and organization has control over OS Storage-as-a-service (SaaS) - Provision of DB-like services, metered like - per gigabyte/month Desktop-as-a-service (DaaS) - Provision of a Desktop environment within a browser Platform as a service PaaS stands for the platform as a service. PaaS provides a computing platform with a programming language execution environment. PaaS provides a development and deployment platform for running applications in the cloud. PaaS constitute the middleware on top of which applications are built. Application management is the core functionality of the middleware. PaaS provides run-time environments for the applications. PaaS provides Applications deployment Configuring application co

Cloud Computing Cloud computing is an emerging style of computing where applications, data, and resources are provided to users as services over the web. Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be made available rapidly and released with minimal service provider interaction. Cloud computing is the use of networked infrastructure software and capacity to provide resources to users in an OnDemand environment. Cloud Computing is an emerging consumption and delivery model that enables the provisioning of standardized business and computing services through a shared infrastructure, the where-in end user is enabled to control the interaction in order to accomplish the business task. Computing resources such as hardware, software networks, storage, services, and interfaces are no longer confined within the four walls of

Matrix Inversion Technique  The inverse of a matrix The inverse of a square n × n matrix A is another n × n matrix denoted by A -1  such that AA -1 =A -1 A=I where I is the n × n identity matrix. That is, multiplying a matrix by its inverse produces an identity matrix. Not all square matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse, and the matrix is said to be singular. Only non-singular matrices have inverses. A formula for finding the inverse Given any non-singular matrix A, its inverse can be found from the formula A -1  = adj A |A| where adj A is the adjoint matrix and |A| is the determinant of A. The procedure for finding the adjoint matrix is given below. Finding the adjoint matrix The adjoint of a matrix A is found in stages: Find the transpose of A, which is denoted by A T . The transpose is found by interchanging the rows and columns of A. So, for example, the first column of A is the first row of the transpo
