The Future of Hybrid Cloud

Building Digital Tablets Horizontal

Let us first define Hybrid Cloud (from Tech Target): “A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, such as Amazon Simple Storage Service (Amazon S3) for archived data but continue to maintain in-house storage for operational customer data.”

Some of the benefits of the public cloud include the pay-as-you-go model without long-term contracts, shared resources and expertise, and scalability. Some of the challenges are lack of control over performance and higher security risk. The latter “security risk” is debatable as you get market expertise in public clouds but you have to contend with multi-tenant data. Private clouds offer the advantage of customizability. This is also in contention as public clouds offer a fair degree of customizability of the systems to meet enterprise specific needs. Hybrid clouds have been offered as an alternative to exclusively using private clouds.

Many are stating that the Hybrid Cloud will disappear and be completely replaced by public cloud. Their contention is that in the near future public clouds will offer all of the advantages of a private cloud plus the advantage of lower cost and scalability.

The dark side of public cloud is seldom discussed: how do you integrate content across various public cloud providers. Just choosing one provider may lead to choosing applications that are only compatible with that provider. This leads to inferior enterprise IT architectures creating, amongst other things, the challenge of getting an unified view. As an example, look at the problem of data integration in managing the IT department if you are using Oracle’s cloud based project management, Service Now for help-desk and Workday for resource management. The challenge of integrating data across these three cloud providers will create the need for a fourth cloud!
