As you walk past her, she smiles and says, “How you doing?” And you both carry on with your day. You think to yourself, “She’s cute, athletic physique — probably on her way to practice.” But little…
I remember that I always liked to mix the meals, especially those that combined savory, sweet, and even slightly spicy flavors. I do not have to say, that I became addicted to Chinese food and in general to Asian; that mixture, 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 better explain basically where the 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 of 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? 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 “take care” of the 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.
Let’s analyze the following case, I was recently in the physical plant in a car assembler and the IT department, together with the company management, decided to migrate the majority of their management and HR applications to the cloud, including, They made a farewell to the old AS400 server that had reigned in the room for more than 10 years. The truth was something sad to see the old refrigerator devouring RPG code and Cobol turning off their lights forever; The truth is that the 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, following the line, imagine now this case, our state-of-the-art vehicle assembler, almost without the assistance of human employees: robot arms take care of most of the heavy work, like joining heavy parts, soldering them, use millimeter precision, calibration of the motor shaft, or more importantly, of the brakes. These arms, communicate to your automation and control software, through cameras and sensors (yes, we speak of IoT, Internet of things), which need to send data at very high speed, so that the system makes a decision, very fast ; they could not wait even 100 milliseconds, the average of a response from a public cloud, because there would be a risk of failure in the precision assembly, or worse, even an accident in the production chain.
As we can see, the situation in our last generation vehicle assembly company is a very specific situation, where definitely, 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 transmission of the data, 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 what are generally taken to support this type of cloud.
But there is no problem, if it has caught your attention, we will talk exclusively, but in another conversation, from the world of private networks, or public networks, or smart sensor networks …
After all, there is always time to converse and share a delicious Chinese rice dish.
