In the second case, the cloud computing model is defined as SaaS and is the opposite of IaaS since we simply use a turnkey software provided by a third-party vendor, who has no technical knowledge of the infrastructure it runs on the vendor is responsible for the reliability and security of the product. A notable example of IaaS services are EC2 from Amazon and Rackspace Cloud Hosting.

We decide how to allocate resources, how many web applications, or database servers we need, whether or not we need to use a load balancer, how to manage backups and so on the installation, monitoring, and maintenance are under our responsibilities.
In the first case, the cloud computing model is defined as IaaS and we basically outsource hardware and every inherent service such as power supply, cooling, networking, and storage systems. In this chapter we will cover the following topics: In this first chapter we will define in detail the term cloud computing and then introduce the model provided by Google, focusing on the elements that are important to us, as developers, and use them to run our first application using the Google Cloud Platform and Google App Engine. This server must be constantly available and respond to clients in a reasonable amount of time, irrespective of the number of clients, or the application won't be usable.Ī noteworthy solution to the hosting problem is cloud computing, which is a rather generic term that usually refers to the opportunity to run applications and services on someone else's infrastructure at a reasonable cost and in a way that is simple and quick for the needed resources to be provisioned and released.
Web applications come with an endless list of benefits from a developer's point of view but there is one major drawback to face every time we want to make our software available to other users: we need a remote server connected to the Internet to host the application. Today, if we want to provide a service for multiple clients and multiple users, we will likely end in with writing a web application. Social networks, e-commerce sites, e-mail clients, online games are just a few examples of a trend known as web 2.0, which was started in the late 1990s and emerged in the past few years.
Any software available over the Internet, usually accessed with a web browser, can be addressed as a web application.
