busines in the cloudThere are many myths and assumptions concerning cloud deployment and on-premises systems. Before selecting the right option for data security, organizations must understand the truth behind these assumptions.

Some of the common myths are as follows:

  • Private cloud is more flexible and meet the basic needs of clients;
  • Private cloud is inexpensive option as compared to public cloud option;
  • Private cloud is more secure and compliant when compared to the public cloud;
  • Reliability and disaster recovery system of a private cloud is better than that of a public cloud;
  • By selecting private cloud, organizations are given adequate scalability that is not possible through public cloud.

Let us discuss in details the reasons why companies choose public cloud

Flexibility

With the passage of time, as your business grows, it becomes essential for your data center to change. As a result, things cannot works as they worked in the past. If your data center facility is reaching its maximum capacity, replacing the facility is an expensive proposal. If organizations are facing financial crises, there must be something else they can do to gain flexibility that is demanded by the businesses and IT. In most of cases, cloud is the ideal option to respond against current changes, the cloud gives control over features such as data storage, accessibility and security. Cloud computing environment keeps the resources just at your finger tips, just a click away. Instead of waiting for days or weeks, IT resources can be received within just a few minutes. 

Cost

As compared to on-premises solution, cloud computing is easy to deploy. Organizations want to pay minimal cost to start up a project. Deployment costs are Opex, not considered Capex. Moreover, the businesses just pay the charges for the storage capacity they require. If an enterprise chooses on-premises based environment, it will have to pay additional charges for staff.

Compliance and Security

Well organized cloud service providers have experienced staff, who can overcome any security breaches better than an IT corporate department, that has limited resources and work under pressure. They also have sophisticated 24 x 7 physical security, electronic surveillance systems, including biometric security features. They also are compliant with many industry standards best practices so you don't have to worry about compliance issues. For example, some public cloud service providers feature certifications, including SSAE-16, ISO-27001, HIPAA, etc.

Reliability and Disaster Recovery

Flood, power outage, fire and other modes of disaster are highly challenging and expensive. Planning for such disasters might require a huge capital investments in staff and infrastructure to cover multiple data center locations.

Scalability

Public clouds service providers are investing continuously in R&D, therefore, cost structure of public cloud is affordable than private cloud. Cloud computing gives an advantage in the form of storage capacity and on-demand compute power scalability. When organizations require more resources, service providers give them access to relevant resources. No need to install new infrastructure or hardware in advance for future use. As a result, businesses grow without paying additional charges to change the current IT system.

As far as on-premises traditional deployment is concerned, IT capability decisions are usually made before installing an application. With on-premises solutions, the companies need to pay for the infrastructure and the servers that will be required in the future. On the other hand, cloud deployment offers granular approach. Cloud computing allows you to select the right resources at the right time when you need them. This will result in huge savings and gives you the opportunity to improve ROI.

When cloud deployment is chosen over on-premises, businesses are given surety to continue their operations in a cost-effective, flexible, reliable, scalable compliant and secure environment.

Public vs Private Cloud:

If a company uses, shared infrastructure like, Gmail, OneDrive, Dropbox, etc. they are using "public" clouds. It is using shared physical hardware. 

If, however, the infrastructure is configured in a private settings, which means, a dedicated infrastructure, i.e., it is only that company using that particular infrastructure, then it is termed as "private" cloud.
