I remember that I always liked to mix meals, especially those that combined savory, sweet, and even slightly spicy flavors. It is safe to say that I became addicted to Chinese food and to Asian cuisine in general; that mixture, that little here and there, give a culinary experience difficult to match. Can you imagine if we could make this combination in the cloud? And no, I do not mean to prepare exquisite Chinese food in the cloud, although, who knows, later...
Before I get hungry, I will try to better explain where this topic is going. We understand that the hybrid cloud is nothing more than the combination of a private cloud and a public cloud, and that together, they provide the technological platform for an organization.
Now, why is there this phenomenon of continuing to have a private cloud? Why not fully migrate to a public cloud and get the enormous advantages in terms of management, security and costs? If it is not out of nostalgia for the old systems or the instinctive fear of computer scientists to make paradigmatic changes, then, "Why do we still find these combinations of clouds so striking?"
Well, it is clear: the need to have data within the internal platform of any company is due to certain factors namely: legal reasons, the level of "due care and attention" of data or when our client needs "Hyper Mega access speed". Remember that any cloud service will have a minimum of latency, from the Datacenter of the region where the service is, to the internal network of the client.
"The hybrid cloud is nothing more than the combination of a private cloud and a public cloud, and that together, they provide the technological platform for an organization"
Let's analyze the following case; I was recently visited the premesis of a car manufacturer and the IT department, together with the company management, decided to migrate the majority of their management and HR applications to the cloud. This migration included a farewell to the old AS400 server that had reigned in the room for more than 10 years. There was an element of sadness to see the old refrigerator devouring RPG code and Cobol having its lights turned off forever. If truth be told, their cookies and coffee were very good. But, despite the migration and with all the benefits of the cloud, there was no way, that ALL the services were migrated.
Why? Well, imagine now this case: our state-of-the-art vehicle assembler with robot arms, almost without the assistance of human employees, takes care of most of the heavy work, like joining heavy parts, soldering them, using millimeter precision, calibration of the motor shaft, or more importantly, of the brakes. These arms, communicate with automation and control software, through cameras and sensors (yes, I’m talking about IoT, Internet of things), which needs to send data at a very high speed to make sure that the system makes a decision very quickly. They can not wait even 100 milliseconds – which is the average time of a response from a public cloud. This minute delay could risk a failure in the precision assembly, or worse, even an accident in the production chain.
As we can see, this is a very specific example, certainly where, you have to have the software in the internal network. It does not matter how many artificial intelligence processes are executed locally: the problem here is the speed of data transmission, since they are acquired by the sensor, processed by the selected Machine Learning model, and returned to the mechanical arm that will then execute its scheduled routines, according to the specific situation.
This is an "industrial" example of the need for a private cloud, and not a public cloud; and for the record, we have not talked about legal or security aspects, which are the aspects generally argued to be advantages of this type of cloud.
If this has caught your attention we can talk in another conversation about the world of private networks, public networks, or smart sensor networks. After all, there is always time to converse and share a delicious Chinese rice dish.
