The concept of the cloud computing not only revolutionizes the way software and hardware usage but the way in which contracts personnel (People as a Service) systems is acquired.
Information Technology and Communication (ICT) have become an integral part of everyday activities, the way we use information and the way we communicate are closely linked to the digital world.
But what about the cloud? Understanding the concept can be facilitated by the following:
A) You decide you no longer need a computer room or data center in your office. You can now hire processing power and storage in the cloud and stop having “irons”: computer servers, cooling system, false floor, light plant, among others, then rents the computing infrastructure as a service (infrastructure as a service).
B) You decide you no longer need the infrastructure in your office computer but also systems that give life and protect the irons, such as operating system, antivirus, database, etc. You go for the platform as rents a service instead of buying these programs (Platform as a service).
C) You decide you no longer need the infrastructure or the platform on your site but also want to buy or develop a system or application to address any special needs of the organization, such as accounting, payroll, etc., then rents a SaaS service (Software as a Service).
The cloud concept is evolving and covers not only infrastructure, platform, and software, but also people who have contracted to install, configure, maintain and support software and hardware of the organization.
Now, such staffs are no longer necessary to have on the payroll; you have the possibility of obtaining services with the same characteristics of the cloud by service units, which is known as People and services “PeaaS” (People as a Service).
People like services has the same characteristics of the other cloud services:
- On demand: you use them when you need them.
- Scalable: You can increase or decrease their consumption as you need to.
- Pay what you use: pay only what you consume.
- Always updated: PeaaS are certified and updated in the latest versions of technologies.
- Ease of hiring: you select the profiles, hardware, and software they need and have them available in a very short period of time.
Currently, organizations compete with the response time, efficiency and consistency of services and products they offer to their customers or citizens. So, they are obliged to devote time to the pursuit of the benefits and savings offered by the cloud. Cloud Computing, in turns, provide you full advantage of IaaS, PaaS, SaaS and PeaaS.
