The drastic expansion in the IaaS market has recently resulted in emergence of many cloud-based services provided by IT vendors. These cloud-based services cover a variety of configurations such as public and private services, and some services adopt several of these configurations and actively build hybrid cloud/multi-cloud environments. The issues posed for customers due to cloud system implementations now include the need for appropriate cost reductions, enhanced security and the integrated operation management of the multi-cloud environment. This paper discusses the portal services based on the NEC Cloud IaaS that are being developed in order to resolve these issues. © 2015, NEC Mediaproducts. All rights reserved.
