The cloud and the development of new apps

The advantages of the cloud for those who develop apps. An exponentially growing trend

<p>Often without realizing it, we are increasingly surrounded by applications that <strong>are based on cloud platforms</strong>. And we will be more and more: the era of the Internet of Things game and the market will reach 300 billion dollars between now and 2020. This means that all the apps related to this trend will be in the cloud, but also in other areas , such as data management, security and mobile (obviously). Let's explore this world.</p>
<p><strong>How does it work</strong>The principle of the cloud is the use of huge data centers (owned by IT giants) that virtualize machines and replace personal or business computers and servers. The calculations related to the apps of many developers are processed in these data centers. <strong>with a number of advantages</strong>what time are we going to see.</p>
<p><strong>Growing trend</strong>Out of almost 20 million developers worldwide, around a quarter works on cloud platforms. The growing trend, because the cloud simplifies and accelerates the process of creating an app.</p>
<p><strong>The technologies</strong>Each app has a final recipient. There are therefore three different dimensions to keep in mind to develop on the cloud, each linked to different technical themes depending on the target: <em>infrastructure as a service</em> (IaaS), mainly addressed to <strong>systems engineers</strong> and computer infrastructure experts – <em>platform as a service</em> (PaaS), per <strong>developers</strong> and solutions experts – <em>software as a service</em> (SaaS), for the <strong>end users</strong>.</p>
<p><span style=A unique environmentLet's think about traditional apps. Those who develop them follow a process that is articulated along a precise path: working in the development environment, then passing to the testing phase, then to pre-production and finally to final production. They are different environments, which require contact with IT experts for the design of a complex platform tailored to users. For a platform that is scalable, reliable and available 24 hours a day, you need investment and expertise. With the cloud, there is no longer a distinction between the development environment, testing, pre-production and production: everything happens in a single environment.

Cheap and fastFor the reasons explained above, developing cloud applications is also a fast and cheap process: they are reduced almost to zero the costs for the purchase, installation, configuration and integration of hardware and software necessary to begin the development of a traditional application. In addition, some services, such as the platform as a service, open up interesting worlds for developers, especially at the company level.

Work remotelyAnother impact of the cloud development system is the possibility of develop locally and work without connection. You can always carry out checks on the PC to understand if the app has been correctly developed and intervene if there are problems on the web front end infrastructure. Generally, to make the real tests, the remote infrastructures that you are using are being deployed, which you access. with an account (clearly, by installing the cloud platform you need to register).

PublicationEven this phase is easier, because there are no longer those technical steps that require time and skills; or rather, now those passages happen in the cloud. Once the tests are finished, make the final deployment of your app and make it visible to users.

scalabilityThe elasticity of the cloud makes it possible to modify the platform depending on user requests, making it in fact scalable to infinity. like having all the hardware you want, whenever you want.
