Hybrid Cloud Computing

Thursday, September 05, 2013

The need to respond more quickly to customers and stay ahead of competition has made the agility and cost-effectiveness of moving applications to the cloud an increasingly appealing option.

In general, the term cloud computing typically refers to a public cloud which is shared by thousands of customers all over the world. These cloud providers usually sell storage space, bandwidth and computing power to companies at much cheaper rates than those of physical servers. Using a public cloud can save your company a great deal of money, however, the shared aspect could cause concerns over accessibility, availability and security.

If you have sensitive information you wouldn't want stored on a public cloud, you would potentially store it on your own private servers. To satisfy this need some businesses set up their own cloud-like computing processes, which act as a private cloud. Private clouds work the same way as public clouds but they are used exclusively for one business and can be firewalled away from the rest of the Internet. This gives the private cloud more security and better performance.

Hybrid Clouds
Since most businesses can't get everything they need out of using a public or private cloud exclusively, they use a combination of both to take advantage of the benefits of each type. Public clouds can be used for less sensitive tasks, and private clouds can be used for secure or vital processing tasks. The combination of both these clouds is the hybrid cloud, and it is quickly becoming the preferred method for many businesses. 

An organization might use a public cloud service for archived data but continue to maintain in-house storage for customer data. Ideally, the hybrid approach allows you to take advantage of the scalability and cost-effectiveness that a public cloud computing environment offers without making critical applications and data vulnerable.

Advantages Of The Hybrid Cloud
Cost Savings: Keeping all of your IT services exclusively internal (on private clouds) or placing everything in the public cloud would require you to spend additional money. A hybrid environment allows you to leverage both systems, reducing the potential costs of hardware, software, and services. Services such as managed hosting can become very expensive, while hybrid computing is available at very reasonable rates.

Scalability: With the hybrid cloud you can mix and match your IT systems and infrastructures between internal private cloud solutions and multiple public cloud environments. This eliminates the need to rely solely on any one system.

Security Management: Security levels vary with each organization and with a hybrid cloud you can maintain security internally, or outsource it to IT Resource. Some organizations may have fewer resources and confidential information to manage and others may find that there are specific providers that offer higher levels of security for their data.

Redundancy: By having your data distributed between multiple sites within the hybrid cloud, you have less downtime and data loss.

Flexibility: Hybrid clouds offer the ability to run individual workloads on either the public or private platforms, taking into consideration cost, performance, security and other requirements. Hybrid clouds provide more flexible solutions when compared to either private or public clouds individually, when you consider the entire workload.

Security Issues In The Cloud
Concerns about the safety of data could be resolved by storing sensitive data on the private cloud, and storing all other data and applications on the public cloud. Another resolution is to carry out critical or security based operations in your own data centers, while using the public cloud to carry out tasks that are larger. By implementing this type of setup you can take advantage of both types of data storage.

Overall, hybrid clouds are designed to quickly assess your needs. Because there are several processes going on behind the scenes to achieve a seamless route between various types of clouds, hybrid is the ideal solution for large-scale projects that can be cumbersome to an in-house server. Using the hybrid cloud would save you the extra costs of purchasing server hardware for a specific project, which would otherwise be unnecessary.

If you have questions on how a hybrid cloud relates to your business, call IT Resource. Our engineers would be happy to meet with you to discuss your needs.
