Battle of Cloud Security: Public Cloud VS. Private Cloud

Nowadays, businesses are making the use of cloud computing technologies to bring revolution in the business environment. Cloud has completely changed the way enterprises, and their employees operate tasks. With the use of cloud computing, you can save IT costs, access documents right on your smartphone, and share files with your employees and clients with ease.

While cloud computing offers multiple opportunities, there are some common issues and pitfalls, as well as different methods with an objective to achieve determined results. One of the serious issues faced by cloud computing users is cloud security.

Therefore, businesses find difficulties in finding the best cloud computing models. Public and Private clouds are the two most compelling models that are continuously gaining popularity in the IT sector. However, both are the powerful models, but when it comes to the cloud security, we need to analyze and compare both of them on the basis of their specific features and functions.

In this blog post, we will compare the Public and Private Cloud computing models on the basis of their security and reliability. This post will help you find the best solution for your business.

  1. Security

Security is the most crucial aspects which is necessary for every business. Cloud security in both a public or private cloud scenario is essential for running a secure business.  With the growing popularity of cloud adoption, more than 70 percent of the businesses have at least one app or a part of data stored in the cloud. And this percentage will grow over the time.

The components of security in the public cloud solution are offered by the third-party cloud service providers.They provide security depending on the industry and type of information stored in a public cloud. In short, they don’t provide enough security and privacy to their business clients.

On the other hand, the private cloud offers robust security because all the security efforts are performed in-house or outsourced by managed security provider.

There are multiple options for businesses searching for enhanced security while reaping benefits from a flexible public infrastructure, such as a cloud-based content delivery network. It provides secured services, DDoS protection and security for web applications and websites. In simple words, it securely transfers the information to the end users with ease.

Public VS. Private Cloud

  1. Stability

It becomes essential to determine whether your cloud solution is available 24*7 or not because a huge amount of critical applications, data, and other services are stored in the cloud.

Both the public and private clouds always guarantee to provide the 24*7 cloud service, but what about in the situation of a cyber attack or disaster? Does your cloud solution have a plan for this particular situation? Do they have built-in redundancy or the capability to take in large amounts of traffic in a DDoS attack? Thus, it becomes essential to consider these situations before moving your business to a particular cloud solution.

Public clouds typically have huge space, but the capability to expand on demand mostly depend on the service provider.

Private clouds, on the other side, have the ability to distribute the workload over different servers but are restricted by the amount of server space that a company owns.

Well, you can opt for a hybrid solution that includes both the public and private clouds. This will help you provide unlimited data storage and also protects your assets in the occurrence of a disaster or cyber attack.

You can also pair your company’s cloud with a CDN that provides complete access to a global network of cloud-based technologies. The CDN network has over 140 points of presence (PoPs) all around the world. If there is a natural disaster in one particular area, there are many other servers that will absorb the traffic to ensure the continuity of your app or website.

  1. Accessibility

One of the biggest advantages of using the cloud is that it makes it super-easy to access the data from anywhere with an internet connection. However, most of the IT experts know that there are multiple layers of steps and considerations to get to the end point.

In a public cloud scenario, the IT staff will never see the physical servers that store the data of the company. In fact, it becomes difficult to know who will have the control to your servers at the datacenter. Companies in public cloud solution pay only for space and for what they user.

Your company’s data could be stored on the same server where other companies also stored their data. Sometimes, cloud service providers manage the Firewalls and other security measures, which frees IT staff from continuous management. But it can also affect the security of your data if something critical is left on the provider’s end.

Access is more restricted with a private cloud solution. The physical servers of a company may be stored in a datacenter, but the IT staff is completely responsible for executing security configurations and monitoring.


Different types of cloud computing models – public, private or hybrid – all are playing a significant role in expanding the growth of the business. You can choose your cloud service provider according to your needs and specifications. Make sure that you consider the Security, Stability and Accessibility of the cloud solution before making any final decision.
