Public or Private: Which cloud is right for you?
Posted on 07/31/13 by Cloud Calculator Staff
Confused as to which cloud solution is right for your company: public or private? Unfortunately there is not always a clear, one-size-fits-all solution. With both options offering their own distinct set of advantages, the best choice is directly dependent on your organization’s unique needs.
Watch this video to learn more about the differences between a public and Private cloud.
What is a Public Cloud?
A public cloud means that the servers you use are shared and securely segmented among a network of users. Most notably, because these resources are shared, the cost savings can be dramatic.
Advantages of the public cloud:
- Servers and applications can be deployed in minutes
- Data is always available, no matter where you are located
- Flexibility means your resources can be quickly adjusted to fit your changing IT needs.
What is a Private Cloud?
In a private cloud, you are using dedicated servers that are only accessible by you. This means that you are receiving the scalability and flexibility of the cloud, but with the peace of mind that comes from knowing your critical information is stored away within a pool of private and dedicated resources.
Advantages of the private cloud include:
- The private cloud offers scalability without raising security concerns, meaning you remain compliant with PCI and HIPPA regulations
- A set of dedicated resources means that your data is kept away from the public and only accessible by you.
- As needs change, your resources are scaled to match, while hardware maintenance, software updates and capacity planning is left in the hands of the data center experts.
Security in the Cloud
Remember, regardless of whether you choose a public or private cloud offering, your mission critical data is only as secure as the cloud provider you choose. For this reason, it is important to ensure that your provider offers the hardware and software needed to keep your data safe.
This should include a healthy mix of:
- Physical Security: 24x7 monitoring, continued video surveillance and onsite guarded access are critical for keeping your data safe.
- Segregation: In order to ensure your data remains protected, the hosting provider needs to offer data segregation and encryption at every stage of a multiple tenant environment.
- Remote Security: This includes verifying the existence of up-to-date software upgrades, antivirus and security polices, secure log-in and encryption methodologies, enterprise grade intrusion prevention systems, and hardware based firewalls.

In short, the question invariably becomes, which does your company value more: The Flexibility and Availability of the Public Cloud or The Security and Scalability of the Private Cloud?
