Many organisations are turning to the cloud for support as this next-generation computing model finds its feet. For many, the thought of going all-in is a continuing concern, so instead, firms are adopting a hybrid approach that utilises the best of on-premises and cloud technologies. It comes as dissimilarities between public and private clouds make using a combination of the two extremely difficult.
Talking about the take-up of hybrid models, Oracle Korea Sales Vice President Lee Hyung-bae revealed that the market has now reached a stage where it is not only IT professionals wanting the cloud but also business owners. This is because utilising the cloud offers many benefits, including efficiency, agility and innovation.
With new competition now being born in the cloud, it is extremely useful for long-standing companies to be able to access the same solutions and leverage them to the best of their ability. There is, however, far more to IT than the new and innovative offerings available in the public cloud. Core applications that act as the engine of a company are not easily changed, nor are alternatives in the cloud always readily available. In addition, vast databases containing years of valuable and sensitive information have been entrusted to the safekeeping of many IT departments. Putting this into a public cloud is not always feasible. As a result, there is an increasing demand from companies to be able to access cost and efficiency-saving cloud solutions whilst maintaining some of their traditional on-premises applications, i.e. the hybrid model.
All of the recent industry surveys have shown one thing in common: the majority of businesses want to use a mix of private and public cloud resources. The problem with this is that there are inherent differences between most private and public clouds. For example, they are often built using different technologies. They behave differently, and utilise a range of operative, consumption and subscription models. It means that all parts of the stack, including applications, monitoring, middleware, infrastructure and security, need to be specialised. This customisation brings its own issues.
With such issues becoming all too obviously apparent, it is likely that many firms will continue to use hybrid models as the complexities of using both the private and public cloud are ironed out. This will allow a degree of traditionalism to be maintained whilst gaining benefits such as scalability and cost reductions.
