What is cloud computing? | IBM

Enterprises eager to undergo digital transformations and modernize their applications are quick to see the value of adopting a cloud computing platform. They are increasingly finding business agility or cost savings by renting software. Each cloud computing service and deployment model type provides you with different levels of control, flexibility and management. Therefore, its important to understand the differences between them.

Common convention points to public cloud as the delivery model of choice; but, when considering the right architecture of cloud computing for your applications and workloads, you must begin by addressing the unique needs of your business.

This can include many factors, such as government regulations, security, performance, data residency, service levels, time to market, architecture complexity, skills and preventing vendor lock-in. Add in the need to incorporate the emerging technologies, and you can see why IT leaders are challenging the notion that cloud computing migration is easy.

At first glance, the types of cloud computing seem simple: public, private or a hybrid mix of both. In reality, the choices are many. Public cloud can include shared, dedicated and bare metal delivery models. Fully and partially managed clouds are also options. And, in some cases, especially for existing applications where architectures are too complex to move or the cost-benefit ratio is not optimal, cloud may not be the right choice.

The right model depends on your workload. You should understand the pluses and minuses of each cloud deployment model and take a methodical approach to determining which workloads to move to which type of cloud for the maximum benefit.
