Although cloud migration has potential for all organisations, not all clouds are the same. Businesses today 

have more than one cloud model from which to choose; public cloud, private cloud, hybrid cloud, or multi-cloud. Beyond this initial choice of cloud model, there are three major cloud service categories to consider 

for cloud deployments; Software as a Service (SaaS), Platform as a Service (PaaS) or Infrastructure as a 

service (IaaS). 

 

In addition, there are various business and technology challenges you will need to manage, including the 

complexity you’ll face when migrating, appropriately estimating the effort to get it done, and obtaining buy-in from stakeholders across the business if migrating at scale. Not every application can move easily. Which 

do you keep, and which do you rebuild? What are your options for rebuilding and modernising applications, 

so they perform optimally in cloud? Once you have moved your applications to the cloud, what’s the best 

way to manage these?
