Some businesses still have reservations about hosting their critical applications and data through a public cloud service. In spite of the significant security measures taken by these cloud service providers, there are those who choose to play it safe and either build their own infrastructure, either on premise or in a private cloud.
There is also another option, which continues to gain popularity. Hybrid cloud infrastructures combine many of the best elements of public and private cloud computing.
When choosing any type of cloud service, it is important to research all of the provider’s security measures and safeguards. Most public cloud providers go to great lengths to keep data safe. Physical and cybersecurity controls at many datacenters rival something you might see in a Mission Impossible movie.
Private Cloud Computing
Despite the extent of these security measures, many companies believe that a private cloud is the way to go simply because they do not trust any third-party with their data. Some would argue that these fears are not completely unfounded, as companies around the world are regularly falling victim to data breaches. While it is unlikely that many – if any – of the high-profile breaches we regularly see in mainstream media are directly related to a public cloud service provider, no vendor can guarantee data safety.
Companies that build and maintain a private cloud generally have the control and the peace of mind that comes with storing data and running applications on premise. One potential drawback, however, is that companies managing and using their own network must also take full responsibility for the security. Maintaining strong security measures and disaster recovery solutions is critical for private cloud networks. While it is unlikely that you’ll need an armed security team like Google has, it’s a good idea to have a robust managed security solution in place.
Public Cloud Computing
While some businesses are hesitant, others are migrating their entire IT infrastructure to a public cloud service. These companies are comfortable with the level of security provided by vendors, and are likely also attracted to the lower costs and convenience public cloud infrastructure can bring. Unlimited scalability, paying only for resources used, lack of large capital expenditures and not having to maintain an IT network are all benefits that attract many companies to a public cloud network. Companies need to be careful, though. A migration of an entire network from private to public cloud might result in unnecessary resources and expenses.
Hybrid Cloud Computing
There is a third cloud option that combines elements of both private and public networks. Hybrid cloud models work because they combine two distinct infrastructures by using technology that enables data and application portability. This allows companies to store their sensitive data in a private cloud without risking external exposure, while leveraging public cloud resources to run the applications that need this data.
Every business has their own, unique technology needs. With a variety of cloud computing options available, companies can choose the one that best fits their data, security and budgetary needs.
