Performance Comparison of Terraform and Cloudify as Multicloud Orchestrators

Studies indicate that by 2022 multicloud models will reach 75% of the cloud computing market. To handle the high-featured set of computing capability on this paradigm, often called "Sky Computing", infrastructure tools such as cloud orchestrators has emerged. This paper analyzes the most referenced tools in the literature such as Cloudify, Heat, CloudFormation, Terraform and Cloud Assembly, as well as the TOSCA standard. The literature review, complemented by a practical experiment, revealed that Terraform and Cloudify presents great affinity with Sky Computing scenarios. In the experiment Terraform outperformed Cloudify in several aspects.
