Private vs. public cloud computing solutions – Which is the best for you?

Untitled

Whether it is a private cloud or a public cloud, it is unanimously agreed that the key benefits of cloud computing includes instant provisioning, scalability, ability to expand the base of the server promptly and virtualized resources. An increasingly large number of public cloud deployments are used by web servers or other development systems where the compliance and security requirements of the bigger organizations and their customers aren’t a big issue. On the other hand, private cloud computing is by definition a single-tenant environment, where the storage, hardware and network are dedicated to a single company or client.

The public cloud is defined as a multi-tenant environment. Let’s take a look at the striking differences between public and private cloud computing so that we can help you make a better decision while choosing their services.

Noteworthy trade-offs of public cloud computing

Rackpace Cloud and Amazon EC2 are some public clouds that have some noteworthy trade-offs. Check them out:

  • Utility model: The public clouds usually deliver the pay-as-you-go model where you have to pay by the hour for the resources that you use. This is indeed an economical way to opt for if you’re tearing down and spinning up the development servers on a daily basis.
  • No particular contracts required: Besides the utility model, you’re simply paying by the hour and if you wish to shut down the server after using it for 2 hours, there will be no contract that requires your ongoing use of the server.
  • Hardware is shared: Since the public cloud is by definition a multi-tenant environment, your server is supposed to share the same hardware, network devices and storage as all the other tenants who are there in the cloud.
  • Hardware performance control not required: In the public cloud, you won’t be able to choose the hardware, storage performance or cache. Your virtual server will be placed on whichever hardware and network the cloud provider designates for you.

Private cloud computing trade-offs

Private cloud computing is a single-tenant environment, where the hardware, network and storage are dedicated to a particular company or client. Here are the common trade-offs.

  • Security: Since the private clouds are dedicated to a specific organization, the data storage, the hardware and the network can be tailored in such a manner that it assures high levels of security that can never be accessed by any other client of the same center.
  • Personalizeable: Storage performance, network performance and hardware performance can be easily specified and customized through the private cloud computing system.
  • Compliance: Did you know that PCI, Sarbanes Oxley and HIPAA compliance can’t be delivered through a public cloud computing system? This is because the network configuration and hardware storage is dedicated to a specific client and hence compliance is much easier to achieve.

Therefore, if you’re into the cloud computing system, make sure you know the differences between private and public cloud computing so that you can choose the best in times of need. For more information on private and public cloud solutions, you may check out FortyCloud.
