Cloud Computing Hype

Why is everyone talking about cloud computing? Drawn-out, expensive IT projects that are planned andimplemented without any benefits for the business stakeholders are commonplace. In contrast, cloud computing offers business users the chance to immediately implement services with usage-based billing that are tailored to their requirements, often without the need to consult with the ITdepartment. However, aspects like security, architecture, availability, and standards are often not evaluated. Cloud consumers find themselves at the mercy of the cloud provider. Scenarios that require changing cloud providersafter a cloud provider goes bankrupt, and the associated moving of data and/or applications, have not yet been sufficiently tested. Business continuity should play a key role from the start of a cloud evaluation process. One of the greatest challenges here is the integration of existing data and systems into the cloud solution. Without integration spanning between clouds and on-premise systems, processes can only be executed inisolation, leading to cloud-specific silos of isolated solutions. Important information for users is not available across processes and systems. Problems that would have occurred in the company’s internal IT are nowshifted to the cloud provider. To prevent “legacy clouds” or solutions that are hard to maintain, it is important to manage the entire architecture proactively and, in particular, the integration into the cloud. Even if cloudproviders want us to believe otherwise, not every aspect of IT can be outsourced to cloud solutions!  Read the paper here.
