Cloud security Explained: Private cloud Vs Public cloud

Cloud computing is growing popular with each passing day and all businesses are adopting cloud computing for hosting their business data and automating their business processes using the cloud computing platforms and services. The big question in business analysts’ minds when they are evaluating the change is how secure will their data be when using a cloud computing platform. In this article, we will focus on the data security options available to businesses when they move their data to cloud computing. 


What is cloud computing?

Cloud computing offers businesses to host their data and manage their business work remotely through the “Cloud”. The backend operations are performed online on a remote location and outcomes are sent to the client’s desktop. The greatest advantage of such a scenario is that businesses can access their work environment online from any device and any place. They are not restricted to their offices to perform business tasks. 

Using a cloud-based application for data management and business operations can be easy on the pocket as well as the overhead of purchasing expensive hardware equipment and data servers are reduced and business can be expanded online without the need of an on premises IT setup. Once the infrastructure is set up using the cloud application, team members can collaborate online and make use of the wealth of data operations and cloud based software tools that are available online for business tasks. Project management software like and data analytics and reporting software like dotnet report builder are examples of cloud based applications that can be purchased to help businesses manage their data and increase productivity for business growth.


How secure is cloud computing?

  1. One important consideration when businesses opt for cloud computing is the question that is at the back of everyone’s mind related to data security. How secure is data when using cloud computing? Is the clients’ data compromised in any way during the data access from point A to point B? Is data open to online vulnerabilities and how to maneuver around that? In this section we will try to address all these questions and focus on data security in a cloud computing application.
  3. Cloud based application systems are fairly secure and data breach is very rare. All cloud computing systems follow the standard data security protocols in their system implementation to guard data during storage and transfer to client’s workstation. There are many cloud security tools available that take extra security measures to keep your data fully secure and reliable. These tools are introduced as different security layers to keep away threats like fraudulent use of data, unauthorized access to data and other security breaches.
  4. Sometimes, businesses may choose a combination of cloud computing deployments to ensure that the solution is personalized enough to meet their specific data security needs. This can be done by introducing some third party security tools that can help business take that extra precaution that develops the trust of their customers when they do business with them that their personal data and information will not be compromised. 

Data security level available to businesses can also differ on the basis of the type of cloud they choose to host their business data and cloud based applications for managing their business processes and operations.  There are three deployment options available: Public cloud, private cloud and Hybrid cloud.


What is Public cloud?

Public cloud is usually a shared pool of storage area which can host a great number of business data and resources in a shared environment. The public cloud decides on which data servers and remote locations to use for storing data from a specific company and this information is not generally available to the client. The data security options for this type of cloud application are regular and follow the standard data security protocols set up by the internet applications for data security and encryption.

Typically, public clouds have massive amounts of space that can help businesses looking for scalability and expansions in their business. They can easily make use of the IAAS or PAAS service providers using the public clouds. The pay-as-you-go options let them grow according to their needs.


What is Private cloud?

Private cloud provides the next level service in terms of security and access control. Organizations that might have sensitive data and want to ensure the highest level of data security opt for this option as they are aware of the exact remote storage location for their data and resources. They can also control access to data and allow for strict monitoring to avoid any violations and data breaches.

Private clouds have extra security features but may come at an extra cost and may be heavy on the pocket. Also, expansions and growth in the system infrastructure may affect the cloud storage requirement resulting in a need for redesigning the whole infrastructural system. 



What is Hybrid Cloud?

A balance between public cloud and private cloud can be the third option that is available for cloud computing called Hybrid cloud. Hybrid cloud lets the business store some data on the public cloud shared by other companies and some more sensitive data can be deployed on the private cloud with extra security measures for maintaining confidentiality and data integrity of the sensitive information. This way a balance is created and the business can experience the best of both options. 

The operation is quite unaffected by where the data is residing and the transactions are completely transparent of the fact that the deployment is hybrid with a blend of public and private clouds. The hybrid solution can also be cost-effective as it uses limited storage for the expensive private clouds and the rest of the data can reside in the public cloud. 




Cloud computing is the way to go forward for businesses if they wish to grow and prosper but business analysts need to keep in mind that performance increases cannot happen at the risk of data security. Data is the most valuable asset for today's modern world businesses so when choosing the cloud computing environment for their businesses, analysts should do a proper evaluation of the type of cloud computing platform best suited to their needs. The cloud computing platform should not only satisfy their operational and functional needs but also keep the business data safe and secure from online vulnerabilities. 

The business migration plan should clearly address all security-related concerns that might arise at the time of cloud computing deployment and only once the business analyst and the top management are completely convinced with the cloud computing IAAS provider’s plan of service and cloud security management provided by the service, then they should proceed with the cloud computing migration of the business.  The migration can also be phased to make sure that no data loss happens and if anything does happen then the data recovery plan should be in place to maintain the integrity of data at all cost.
