Obviously, cloud computing is not just a fancy trend anymore. Quite a few SaaS offerings are already built on platforms like Windows Azure. Others use Amazon’s EC2 to host their complete infrastructure or at least use it for additional resources to handle peak load or do “number-crunching”. Many also end up with a hybrid approach (run distributed across public and private clouds). Especially hybrid environments make it challenging to manage cost and performance overall and in each of the clouds.

In this blog we discuss the reasons why you may want to move your apps into the cloud, why you may need a hybrid cloud approach or why it might be better to stay on-premise. If you choose a cloud or hybrid-cloud approach the question of managing your apps in these “Silos” comes up. You want to make sure your move to the cloud makes sense in terms of total cost of ownership while ensuring at least the same end user experience as compared to running your applications the way you do today.

Cloud or No Cloud – A question you have to answer

The decision to move to the cloud is not easy and depends on multiple factors: Is it technically feasible? Does it save cost and how can we manage cost and performance? Is our data secure with the cloud provider? Can we run everything in a “single cloud”, do we need a hybrid-cloud approach and how do we integrate our on-premise services?

The question is also which parts of your application landscape benefit from a move into the cloud. For some it makes sense—for some it will not. Another often heard question is the question of trust: We think it is out of question that any cloud data center is physically or logically secured with highest standards. In fact, the cloud data center is potentially more secure than many data centers of small or medium sized enterprises. It boils down to the amount of trust you have in your cloud vendor.

Now, let’s elaborate on the reasons why you may or may not move your applications to the cloud.
