Analyzing the Differences Between the Public and Private Cloud

public_vs_private_cloud_computing

A recent Open Data Center Alliance report indicated both private and public cloud vendors should be confident about their prospects for the foreseeable future. According to the study, more than three-quarters of organizations will move at least 40 percent of their database software to the cloud by 2015. About half of respondents endorsed private cloud applications for their servers, while 25 percent said they favored the public cloud.

Public and private cloud servers may function similarly, but they offer different advantages. Here is a look the types of services offered by each.

Public clouds
Public cloud services cost less, with applications that are easier to implement and upgrade in the future, according to an esds blog. The majority of IT labor is outsourced to providers, so companies no longer have to focus much on tech-related issues. In addition, public cloud vendors are responsible for developing and implementing new software.

Private clouds
Jamal Khawaja, CIO at Information Technology Services, blogged about the advantages of private cloud usage for Enterprise CIO Forum. Khawaja mentioned a former employer whose software had not been tested – let alone updated – in about five years. The issue, he said, was that management would acquire new software only when it was beneficial at a corporation-wide level.

Private clouds are especially useful for companies that “cannot afford to have their data compromised,” according to Khawaja, such as national security agencies, and private vendors can offer protection in a way public providers cannot. In addition, private services can enable companies to establish more customized servers and applications.
