Today, 20 years later, we cannot imagine a world without the internet, without email and without other technologies that arrived a few years ago and that we could not even imagine 20 years ago.
Last week I wrote an article, called What does the "cloud" bring us?. Risky, since there are as many opinions as there are people; as I am still alive after the experience and skipping the exit box, this week I will try to start with box 1, that is, define What is cloud computing?
Definition:
"Cloud computing is a pay-per-use modality of computing services (IaaS) and value-added services created on top of the former (PaaS, SaaS and SOA interoperability), with immediate contracting and delivery of them."
Although the term "computing resources" is better understood than "computing services", I prefer the word service. Implicit is a service-level agreement that encompasses scalability, security, availability, and management.
The computing resources we already know what they are: CPU, RAM, storage and network transport.
Value-added services are Platform as a Service (PaaS) providers that offer a platform to run your applications, and Software as a Service (SaaS) that rent you the use of applications without acquiring anything.
The finalization of the definition refers to on-line contracting and immediate delivery, which implies process automation and scalability (elastic computing).
I believe that the biggest advance we will see in the short term in the cloud is the interoperability of applications, automating the manual production processes of companies.
I'll explain: When a customer places an order with me in their purchasing system, the order will appear in my ERP and, automatically, that order will be auctioned among the suppliers that have their systems connected. The winner of the auction will enter the order into their system and automatically the order will appear in the Order Entry of the ERP of the logistics warehouse. It will load the product truck, feed back customers' systems to track the status of the order, and all that with indispensable human intervention. The technology already exists, I know companies that have it, the need only needs to mature and the cloud is an accelerator.
And since it is true that several heads think better than one, I encourage you to improve the definition, which is not difficult ;-)
