As enterprises warm up to cloud computing, they generally opt for a hybrid cloud architecture. A hybrid cloud is an integrated cloud service utilizing both private and public clouds to perform distinct functions within the same organization.
By using both private and public clouds services, enterprises are allowed to allocate their data, applications, and other resources to either its dedicated private cloud or to third-party public cloud infrastructures such as Amazon AWS, Windows Azure, Google Compute Engine, etc.
Hybrid cloud architecture also allows the balance between the differing demands of infrastructure and enterprise business. Since hybrid cloud infrastructure uses technology already on hand, it assures business leaders of using familiar products while slowly migrating into new territory. It also ensures a return on investment for current technology systems. Gartner analysts believe that by 2020 a “no-cloud” policy will be just as rare as a “no-internet” policy is today.
Cloud computing helps organizations achieve a wide range of business goals, including speed, productivity, readiness, reliability, security, and cost reduction. Enterprises are a bit slower than smaller, younger companies to adopt a full cloud model, but there are significant benefits and very few drawbacks of adapting to private cloud services.
Benefits and drawbacks of private cloud services
Increased security benefits
The illusion if insecurity in the cloud has been refuted numerous times. As previously mentioned, experienced cloud computing providers have the resources and tools to handle and potential combat data breaches and other perceived risks in the cloud.
Third party support
If something goes awry, the provider has to ensure the problem is addressed and promptly fixed.
The staff making up the cloud computing infrastructure are highly qualified in security, ongoing maintenance, and standards governance. Using third-party experts frees up time for your team to focus on their prospective skill areas. When opting for a personal cloud, this expertise isn’t a given. Your company would have to hire new people and spend a great deal of time and money to train in-house cloud experts.
Many studies and TCO analysis outline the great savings potential of converting to 100% cloud usage. Companies from SMB size to enterprise particularly have an incentive to convert to full cloud usage as they tend to have large datasets.
In a world where security breaches at large corporations dominate the headlines, the ambiguity that surrounds cloud computing can make securing the enterprise seem daunting. Concerns about security are one of the primary reasons why businesses consider bringing their cloud infrastructure in-house.
Migrating large datasets into the cloud could potentially have a significant upfront cost. Your company will also be liable to pay for as much space as is being used. If you were to go down the route of a personal cloud, you would be able to keep your on-going costs to a minimum, although the upfront expenses will likely be high. Also, with third-party computing, your company will need to pay for more space in any event that you run out.
