Nowadays hardly any company can do without software giants like IBM, Microsoft, SAP and Oracle. These companies that hold a (virtual) monopoly have used their market position to maximize their profit through obscure license models and complicated contractual regulations. Many clients look for support to avoid losing their overview and control of costs entirely in the jungle of licenses and contracts.
Constantly changing license models and changing contract variants from the large software providers are deliberately designed to unsettle the client. But the IT strategy of every company and the resulting new demands (virtualization, outsourcing, cloud computing, home office, bring your own device, etc.) have a significant influence on the right licensing and therefore on IT costs.
