When it comes to Cloud Computing we still have people who have questions about it, but rest assured, as we delve deeper into this technology we realize that its concept is much simpler than we imagine. Cloud Computing refers to hardware that has a layer of software capable of virtualizing applications, and has an orchestrator that allows the management of this software layer responsible for virtualization.
Now let's understand the difference between a traditional Data Center and Cloud Computing, but first we must understand how each works separately:
A traditional Data Center is an infrastructure consisting of a set of hardware, mostly servers, that run 24/7 to keep your data stored and accessible at any time.
The Data Center can be kept on or off the premises of the company and great care should be taken with regards to temperature, humidity and security to create the best environment for the high-performance hardware. The use of a traditional Data Center has a very high cost of maintenance, equipment purchase, energy and computing engineers who take care to make adjustments in infrastructure and upgrades.
Cloud Computing, unlike a traditional data center, it is made up of physical machines and a layer of software capable of creating cost savings to the environment, reducing energy consumption, physical space and optimization of the technical team. In addition to bringing savings in relation to a traditional data center, it is capable of balancing virtual servers in different equipment, automatically and transparently, prioritizing environment availability.
Data is stored in more than one location, replicated across multiple servers geographically spread.
This brings greater security because the data is kept in different servers and places. This elasticity gives companies a moldable environment that suits their needs, without having to worry about infrastructure surpluses.
Besides the fact that companies no longer need to update the hardware and maintain their own infrastructure, the big difference is being able to pay for an infrastructure that is appropriate to their needs, without having surpluses. Another advantage is having a technology that reduces the risk of being subjected to natural disasters by being physically in a location in the case of a traditional data center, whereas the Cloud is spread in several Data Centers physically reducing the likelihood of loss of due to disasters or even server failures.
The security of a traditional Data Center and a Cloud is a topic that still raises many doubts for those who do not have much knowledge on the subject, therefore do not give so much attention to these questions, because it is a simple process linked to trusting the company that built the infrastructure of both the Cloud and the traditional Data Center.
It is necessary to follow the norms, standards and criteria of ISO 27001 and be classified as a TIER3 provider to be able to give due security both in a traditional Data Center and in a Cloud Computing, that in spite of the name, remains a Data Center but with last cutting edge equipment that bring cost saving solutions, optimizations, performance and scalability.
Now we can understand that Cloud Computing is an enhanced Data Center, where it offers a flexible and scalable environment to make changes to machines such as processing power, memory and virtual licenses. Offering an environment with cost proportional to the service used and more appropriate to the business environment.
The traditional Data Center continues to be a dedicated infrastructure, without sharing space with other organizations within the same hardware, causing companies to pay for something they end up not using. In addition to having to invest in the purchase of new equipment when the need arises to increase the computing power, the hiring of a team to maintain and add the high cost due to the energy consumption.
We came to the conclusion that the costs for maintaining a traditional Data Center are very high. We are changing this paradigm that we need to have our own server, software, professionals, give training to the engineers and bear the energy costs that end up making the operations much more expensive. This new model where we use only what we need without having to pay the surplus, sharing the same space has been gaining more and more popularity in the market and becoming ever increasingly efficient.
The need for dedicated professionals is a thing of the past, today almost all areas of the market are already following this model of sharing (Netflix, Uber, Airbnb, Waze) where it comes down to economy, flexibility and focusing on the business itself.
Now that you know the difference between a traditional Data Center and Cloud Computing, understand the right time to migrate your physical server to a Cloud solution.
