Let’s talk about Cloud Computing
1/3. Why “cloud”?
This expression was born because is very normal to use graphic representations in cloud format to show the internet as part of the process on IT diagrams, representing something that you can’t touch.
Simple as that!
That is the reason why people call everything that is on the internet of “Cloud”.
2/3. “Infinitely available” and “flexible” computing
In the Cloud, the major advantage is the flexibility to create and destroy resources. You don’t need to stay with a computer if you don’t need it anymore.
This capability changed radically the way people buy resources for their business because now you can create strategies to pay exactly for what you are using.
If your audience grows up, you add more computers (infinite resources) or increase dynamically the existent ones on your infrastructure. If your audience goes down, you can destroy these extra computers or back to your previous configuration.
3/3. Cost-benefit ratio
The image below shows a traditional data center vs cloud provider
(AWS in this case, but the concept is applicable to any cloud vendor).
Pay attention to the blue line that is our computational force and the red line that is our demand/customer.
Look that in Traditional architecture we always lose money 🙁
If we don’t have enough demand our computer is underused. But if our demand grows up fast, probably a part of our customers will have problems to use our solution.
On a Cloud environment as you can see the computational force is flexible and you just pay for what you really are using.
As you can imagine, still has a lot of Cloud Computing aspects that we didn’t cover on this article.
This was a short briefing.
Hope that you enjoyed and feel free to leave your comments.
See you next time!
