HYBRID CLOUD BENEFITS
Although cloud services can drive cost savings, their main value lies in supporting a fast-moving digital business transformation. Every technology management organization runs under two agendas: the IT agenda and the business transformation agenda. Typically, the IT agenda has been focused on saving money. However, digital business transformation agendas are focused on investments to make money.
The primary benefit of a hybrid cloud is agility. The need to adapt and change direction quickly is a core principle of a digital business. Your enterprise might want (or need) to combine public clouds, private clouds, and on-premises resources to gain the agility it needs for a competitive advantage.
PUBLIC CLOUD: ADVANTAGES AND DISADVANTAGES
If you contract with a service provider such as AWS or Azure, you’re using a public cloud and essentially renting a slice of their distributed data center infrastructure. Public clouds deliver cloud infrastructure as a service (IaaS). They offer massive economies of scale, scale elastically, and run fully automated, so it’s nearly impossible for an on-premises data center to compete on price or efficiency.
PRIVATE CLOUD: ADVANTAGES AND DISADVANTAGES
If you set up a dedicated cloud infrastructure for your enterprise, you are using a private cloud. It’s a private cloud whether you manage it yourself or hire a third-party service, and whether you host it in your data center or off-premises.
IS HYBRID CLOUD RIGHT FOR YOU?
Not everything belongs in a public cloud, which is why so many forward-thinking companies are choosing a hybrid mixture of cloud services. Hybrid clouds offer the benefits of both public and private clouds and take advantage of existing architecture in a data center.
The hybrid approach allows applications and components to interoperate across boundaries (for example, cloud versus on‐premises), between cloud instances, and even between architectures (for example, traditional versus modern digital). The same level of distribution and access flexibility is also needed for data. Whether you’re handling workloads or datasets, in the dynamic digital world, you should plan for things to move around in response to evolving needs. Where applications or data live today might not be the best place for them to live over time.
