  In this paper, we propose a server structure proposal and automatic
performance verification technology which proposes and verifies an appropriate
server structure on Infrastructure as a Service (IaaS) cloud with baremetal
servers, container based virtual servers and virtual machines. Recently, cloud
services have been progressed and providers provide not only virtual machines
but also baremetal servers and container based virtual servers. However, users
need to design an appropriate server structure for their requirements based on
3 types quantitative performances and users need much technical knowledge to
optimize their system performances. Therefore, we study a technology which
satisfies users' performance requirements on these 3 types IaaS cloud. Firstly,
we measure performances of a baremetal server, Docker containers, KVM (Kernel
based Virtual Machine) virtual machines on OpenStack with virtual server number
changing. Secondly, we propose a server structure proposal technology based on
the measured quantitative data. A server structure proposal technology receives
an abstract template of OpenStack Heat and function/performance requirements
and then creates a concrete template with server specification information.
Thirdly, we propose an automatic performance verification technology which
executes necessary performance tests automatically on provisioned user
environments according to the template.
