Cloud computing is a model for enabling network access to configurable computing resources that can be rapidly provisioned with minimal management effort. It involves delivering computing resources like servers, storage, databases, networking, software, analytics and more over the internet. Key characteristics include on-demand self-service, ubiquitous network access, resource pooling, rapid elasticity and pay-per-use. Common types of cloud services are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). Challenges of cloud computing include security, privacy, reliability and customization issues.

What is Cloud Computing ??Cloud computing is about delivering computing resources (Hardware and Software) as on-demand service or virtual infrastructure to clients over the Network. "Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction."

Moving to cloud doesn’t mean no system administration. Increasing resources doesn’t compensate for bad architecture of your system/application. Still configuration and versioning issues with large cluster of machines. Performance and Scaling are more than problems with resources Applications/Systems migration is not just a click away

Building Blocks The cloud computing model is comprised of a front end and a back end. They are connected through a network Front End The front end is the kind of user interface by which the user interacts with the system. The front end is composed of a client computer, or the computer network of an enterprise, or the applications used to access the cloud. Back End The back end is the cloud itself The back end provides the applications, computers, servers, and data storage that creates the cloud of services.

Infrastructure as a Service (IaaS) It consists of the physical assets — Virtual machine, servers, network devices, storage disks, etc. We have control of the operating systems, storage, deployment applications, and, to a limited degree, control over select networking components. Service providers offers capacity for rent, basically hosted Data Centers & Servers Example Print On Demand (POD) The POD model is based on the selling of customizable products. PODs allow individuals to open shops and sell designs on products. With cloud storage capabilities, a POD can provide unlimited storage space.

Platform as a Service (PaaS) It provides— operating system, programming language execution environment, database and web server It provides a way to deploy applications to the cloud using programming languages and tools supported by the provider. Platform as a Service (PaaS) provides access to operating systems and associated services. Example PaaS has providers such as Amazon's Elastic Compute Cloud (EC2), Google App Engine Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers.

Software as a Service (SaaS) Applications run here and are provided on demand to users. Example Software as a Service (SaaS) has providers such as Google Pack. Google Pack includes Internet accessible applications, tools such as Calendar, Gmail, Google Talk, Docs, and many more. Social Networking Websites (Facebook, Twitter, soundcloud)

Types of Cloud Public clouds are available to the general public or a large industry group and are owned and provisioned by an organization selling cloud services. i.e. Amazon Private clouds exist within your company's firewall and are managed by your organization. They are cloud services you create and control within your enterprise. Private clouds offer many of the same benefits as the public clouds — the major distinction being that your organization is in charge of setting up and maintaining the cloud. Hybrid clouds are a combination of the public and the private cloud using services that are in both the public and private space. Management responsibilities are divided between the public cloud
