In other words, cloud computing provides us with technology innovation that we must choose to apply based on how and to what extent it helps us fulfil our business requirements. Methodology, governance and even a project plan are not prerequisites, leaving the door wide open for those who want to create (or recreate) convoluted and ineffective technology architectures that are distinguished from past failed on-premise environments only with the ‘cloud’ label. The broad commercialisation and attractive price points of public cloud computing platforms make cloud-based IT resources accessible to pretty much any organisation with interest and a sufficient credit rating. The proliferation of cloud computing is a double-edged sword, readily swung by both professionals and amateurs alike. More so than most IT trends we have seen come and go over the past couple of decades, cloud computing has infiltrated the IT mainstream as a collection of innovations, technology advances and intelligent new applications of not-so-new IT models and technologies.
