In this post I will look at the three different service models for cloud computing as defined by NIST. More specifically I will look at the management and operations overhead for each one of the models and compare it…
Let’s look at how things have been done in the past. Traditionally enterprises have been responsible for managing their own IT infrastructure as well as the software stack that runs their applications. For small companies that meant hiring polyglot employees with wide range of skills varying from low level networking to high level application support. For larger ones, that can afford more staff, it meant creating specialized teams responsible for only networking infrastructure, or only storage or servers and virtualization. However for lot of those enterprises the core business has never been managing IT infrastructure – the only thing they are interested in is to manage their line-of-business (LOB) apps.
