What is Cloud Computing? Guide for beginners

Over the past few years, Cloud Computing has become increasingly important where everybody now talks about the "cloud". But what is meant by this term? Business applications are moving to cloud computing. The change is faster than ever, the shift from traditional software models to the Internet took place at an ever more pace in the last 10 years. Looking ahead, cloud computing in the next decade promises new ways to collaborate anywhere through mobile devices.

Traditional business applications have always been very complicated and expensive. The quantity and variety of hardware and software required for their execution are overwhelming. You need a whole team of experts to install, configure, test them, run them, protect them and update them.

If you multiply this for tens or hundreds of applications, it is easy to see why even the biggest companies with the best IT departments are not able to get the applications they need. Small and medium enterprises are literally out of the game.

Cloud computing eliminates all of these problems because it does not require the client to manage the hardware and software. The shared infrastructure provides a function similar to that of the public services with the user pay only for the functionality they need, upgrades are automatic, and scaling up or down is simple.

The cloud-based applications can be operational in a few days or weeks and are less expensive. With a cloud application, simply open a browser, log in, customize the app and start using it.

Businesses are running all kinds of applications in the cloud, such as the management of customer relationships (CRM), human resources, accounting, and much more. Some of the largest companies in the world have transferred their applications in the cloud.

The latest innovations in cloud computing are making increasingly mobile enterprise applications, collaborative and similar to wide spread consumer applications like Facebook and Twitter. The users of these applications are expected to receive important information in real time and even business applications in the cloud are starting to move in this direction. In the Cloud, keeping up with the work is easy as also to stay updated on the events of personal lives on Facebook.

The Cloud is stated then as a strategic element of the innovation process with its ability to generate new value, encouraging both the rationalization of processes structured back-end, both supporting knowledge workers to the front end, committed to interact with dynamic markets that require quick decisions and quick reactions.

For this reason, the Cloud is no longer about just CIOs and IT whose role it is still necessary to ensure the integration of the entire system but it becomes an enabler of a possible competitive advantage that the CEO's, CXO, the various Line of Business Manager will increasingly have to deal with.

The Cloud allows a world of innovative solutions that allows businesses large and small, public and private, to optimize cost and performance using hardware and software resources remotely without having to provide dedicated IT infrastructure because it eliminates the risk component on technological choices allowing companies to focus on their core business and reduces fixed costs, thanks to a drastic decrease of dedicated staff and a structure of modular pricing along with the continuous updating ensures end-to-end centralized and high protection of both logical and physical data.

The Cloud allows Data storage services that are accessible at any time and from anywhere on the web and allows you to set, manage, and scale a relational database in the cloud while building dynamic web sites that are hosted on the cloud in order to have maximum control of all the processes of publication, updating and maintenance of the platform.

The Cloud allows remote video encoding and distribution of live and on demand multimedia content to the distribution of the video without the need for software installed on local servers, video distribution of stations located geographically on the teritory with the ability to manage schedule independently.

The Cloud allows broadcast on the internet video recording of the board meetings of the Public Administration, creation of digital TV platforms in the cloud, management of all digital assets remotely, management and optimization of all business processes, management of the entire process of managing, monitoring and sending of e-mail marketing campaigns, providing a virtual space on which to store and perform backups for data protection.

The Cloud allows the recovery and restoration of the technological infrastructure in a short time due to the malfunctioning of the system and allows the system to distribute the load of a specific service on different machines installed in order to achieve optimum utilization of resources, maximize productivity, minimize response time, and avoid the overhead of the infrastructure.

The Cloud allows you to automatically scale the solution during peak demand based on load requirements to maintain the same performance, monitoring of system performance in terms of peak views, bandwidth and other parameters.

Cloud solutions allow a significant reduction of storage costs associated with the digital asset management, updating and maintenance of the platform. You also do not need initial technology investment, and you can also get savings on the energy front with solutions that are highly scalable, modular and on demand services can be tailored according to the specific needs of the customer in terms of functionality of the platform (Traffic volume, space, bandwidth, computational complexity of the machines, time restrictions) and depending on the budget.

The company shall not have to acquire durable assets, the infrastructure is scalable and therefore adapt quickly and flexibly to changing size, of the markets while cloud solutions can reduce the resources used to manage all the processes related to online services that normally are managed locally.

Thanks to the systems of backup and disaster recovery there is greater assurance on the reliability of data and data protection and address more effectively the changes to which companies and organizations are subject while reducing inefficiencies resulting from hardware and software problems. Cloud solutions are based on redundant structures whose failure can be restored quickly. With the many options you can protect your data and easily restore malfunctioning services.

Cloud solutions exceed all geographical limitations arising from the management of online services locally, giving access to anyone, anywhere.
