Cloud Computing The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Different services — such as servers, storage and applications —are delivered to an organization's computers and devices through the Internet.

Organizations can choose where, when, and how they use Cloud Computing

Cloud computing service modelsSoftware as a Service (SaaS): is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

Platform as a service (PaaS): can be defined as a computing platform that allows the creation of web applications quickly and easily and without the complexity of buying and maintaining the software and infrastructure underneath it.

Infrastructure as a Service(Iaas): is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it

PaaS (Contd.)Cloud computing has dramatically changed how business applications are built and run. Delivering a new application is now as fast as opening your internet browser.

Paas is a proven model for running applications without the hassle of maintaining the hardware and software infrastructure at your company.

The consumer also controls software deployment and configuration settings. The provider provides the networks, servers, storage, and other services that are required to host the consumer's application.

Google App Engine (GAE)

Google App Engine is a Platform as a Service (PaaS) offering that lets you build and run applications on Google’s infrastructure.

App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs change. With App Engine, there are no servers for you to maintain. You simply upload your application and it’s ready to go.

GAE (Contd.)Persistent storage with queries, sorting, and transactions.

Automatic scaling and load balancing.

Asynchronous task queues for performing work outside the scope of a request.

Scheduled tasks for triggering events at specified times or regular intervals.

Integration with other Google cloud services and APIs.

Amazon Web Services (AWS)

Amazon Web Services (AWS) is a bundled remote computing service that provides cloud computing infrastructure over the Internet with storage, bandwidth and customized support for application programming interfaces (API).

AWS is geographically diversified into regions. These regions have central hubs in the Eastern USA, Western USA (two locations), Brazil, Ireland, Singapore, Japan, and Australia. Each region comprises multiple smaller geographic areas called availability zones.

AWS (Contd.)AWS offers a variety of services, all designed to deliver one set of functionality.

The AWS infrastructure is failure-prone, and Amazon achieves service robustness through redundancy. For those services that Amazon offers service level agreements (SLAs), it commonly maintains three copies of the computing and data associated with a service.

AWS is offered on an on-demand, pay for what you use model.

Services are offered on a region- and availability zone-based partitioning.

Easy to build and deploy an application that runs reliably even under heavy load and with large amounts of data
