Introduction

A new trend in the IT industry has seen an increasing number of companies moving their data online, taking advantage of the more cost-effective cloud and its features. Cloud computing refers to the provisioning of resources without the need for capital expenditure, in which the Cloud Service Provider (CSP) provides all of the hardware and customer lease access. The CSP is also responsible for disaster recovery, so that the customer only pays for the resources that they use.
