Busted: 5 Common Myths About Cloud Computing

In today’s tech world, more and more companies are deciding to transfer to the cloud. They believe that this move will provide massive advantages to their business.

Others don’t want to yield to the mainstream and prefer to stay in the traditional environment. They say that the cloud is unreliable and the risk is too great.

But who is right? And what’s the truth when it comes to computing in the cloud?

In this article, I’ll look into the myths concerning cloud computing and find out which of them are true and which of them are false.

Myth #1: The Cloud Is Not Secure

The main concern of those who want to transfer to the cloud environment is security.

The cloud environment is constantly developing, and security is not an exception.

While cloud security may have once been fragile, today it has significantly advanced.

Currently, to ensure enhanced security, most cloud providers support multiple levels of protection.

According to “2016 Spotlight Report” done by CloudPassage, “encryption of data at rest (65%) and in motion on networks (57%) tops the list of most effective security controls to protect data in the cloud.”

Some of the popular and effective security measures are multi-factor authentication for access control and intrusion detection and prevention.

It should also be mentioned that the security risks that exist in the cloud are no different from those that are encountered in-house.

In the same report, CloudPassage found out that fewer companies – 21% of respondents – tend to see a higher risk of security breaches in the cloud than in the traditional environment.

At the same time, 55% of companies state that they have not experienced any incidents concerning cloud security.

Thus, all the cloud security issues may not be completely solved at the moment, but data security has progressed greatly, and will become even better in the future.

Myth #2: The Cloud Is More Expensive Than the Traditional Environment

In fact, the cloud may be cheaper to operate in because it provides numerous cost benefits and has the capability to considerably reduce overall expenses.

According to iCorps, for an SMB it may be up to 40 times more cost effective to operate in the cloud environment than to build, run, and maintain its own IT system.

A study by Rackspace Hosting revealed that 88% of cloud users saw actual cost savings.

Moreover, 56% stated that the adoption of the cloud technology contributed to growing profits for their companies.

More precisely, it is cheaper to operate in the cloud because companies don’t have to hire a lot of staff members to maintain their on-site equipment.

The same study by Rackspace Hosting highlighted the fact that due to the adoption of the cloud, 60% of respondents no longer require a large IT team. Instead, they are able to place a greater emphasis on strategies and innovations.

Myth #3: The Cloud Is a Synonym for SaaS

People tend to use the term cloud as a synonym for SaaS. This may lead to underestimating numerous cloud’s capabilities.

Let’s at first define the two terms.

  1. SaaS, or Software as a Service, is a model of delivering an application that functions as a service and is centrally hosted.
  2. The cloud is a practice of using remote servers to store, manage, and process data instead of using on-site servers and equipment.

John Starmer, Director of Education at Kumulus Technologies, clearly defines the difference between the terms:

SaaS is a part of cloud computing and is one of three cloud services that is focused on providing users access to software functionality rather than the ability to  build software (PaaS) or manage cloud infrastructure (IaaS).”

Thus, SaaS is only one of the variations of the cloud. It may not suit everyone’s needs, but there are other forms of the cloud that will do that for sure.

Myth #4. The Cloud Phenomenon Is Temporary and Will Soon Fade Away

The basis of this myth is the idea that the cloud is a relatively new concept and it will not last long.

But in fact, the cloud continues to become more and more rooted in both personal and professional spheres.

The cloud market is developing rapidly. More and more businesses are deciding to transfer to the cloud environment because it provides numerous benefits such as fast scalability, cost effectiveness, and many others.

According to TechTarget, 41% of companies are going to increase their investment in the cloud technologies.

Gartner predicts that by 2020 a corporate co-cloud policy will become as rare as a no-internet policy today.

By 2020, the cloud will contain 40 zettabytes, which is 400 billion gigabytes of data.

Myth #5: The Cloud Will Not Replace Traditional Data Centers

The cloud technology is developing rapidly, and it is predicted that it will at some point replace most traditional data centers.

According to a white paper by Cisco, it is predicted that by 2020, 92% of all the workloads will be based on cloud data centers, and consequently, only 8% will be left for traditional data centers.

However, the cloud environment won’t completely replace traditional data centers.

The same Cisco white paper shows that by 2020, workload density, which is the amount of workloads per physical server, will be about 12, compared to 7.3 in 2015.

At the same time, by 2020, workload density for traditional data centers will comprise 3.5, while in 2015 it was 2.2.

Another reason why the cloud won’t completely replace traditional data centers is that a number of crucial applications built to run in a traditional IT infrastructure will not be specifically reconfigured for the cloud environment.

Thus, cloud servers will still have to run traditional server operating systems and crucial applications, including Linux, Solaris, Oracle DB, and so forth.

Wrap Up

Although cloud computing is a relatively new concept, it has already become widespread in both personal and professional spheres, and it clearly provides a lot of benefits.

At the same time, the myths about the cloud may give an impression that all of the benefits of the cloud don’t outweigh its negative aspects.

Here are the key findings when considering those myths:

  1. Cloud security has long been the main concern but the cloud is constantly developing, and its security is being enhanced by providing various levels of protection such as data encryption, intrusion detection and prevention and so forth.
  2. The cloud is cheaper and more cost effective to operate than the traditional environment.
  3. SaaS is not a synonym for the cloud but it is only one of the variations of the cloud.
  4. The cloud is becoming more and more rooted in both personal and professional spheres and is unlikely to disappear in the near future.
  5. The cloud won’t completely replace traditional data centers because cloud servers will still have to run traditional server operating systems and key applications.
