The Open Cloud Movement is gaining momentum through cross-layer optimization in IaaS, PaaS, networks and data centers, due to the rise of Open Cloud platforms and technologies such as OpenStack and CloudStack.

In the cloud field, there is a wide range of related technology and different technologies are deployed in each service. In some cases, this results in user inconvenience or vendor lock-in.

These challenges are being met through interface standardization with a focus on IaaS or management related systems by de jure standard of ITU-T and IEEE, DMTF (Distributed Management Task Force: an industry organization which creates standards that enable interoperable IT management), and de-facto standardization of SNIA (Storage Networking Industry Association: an industry organization which advances IT technologies, standards, and education programs for all IT professionals). In Japan, GICTF (Global Inter-Cloud Technology Forum: a private association consisting of companies such as NTT and Hitachi, Ltd., and other experts) supports inter-cloud linkage, quality control and standardization.

On the other hand, AWS or so-called Cloud Native companies, don’t participate in these standardization activities. Instead, they expand their cloud businesses with original API’s. With API’s scale merit and innovative services, these companies gain significant competitive advantage, which outweighs user concerns like vendor lock-in, and drives forward the substantive de facto standardization. Many of the cloud service providers and third parties explore opportunities to coexist with Amazon by offering AWS compatible API in management layer services and solutions that are adaptable with multi-cloud.

The resulting drive toward open-cloud is evident in OpenStack and CloudStack (open-source based cloud infrastructure). This move accelerates Open Cloud deployment by cross-layer manner in IaaS, PaaS, network and data center layer.

The IaaS layer is seeing an adoption of cloud infrastructure software. Often called CMS (Cloud Management System) or Cloud OS,  this open-source-based cloud infrastructure software manages server, storage, and network with OpenStack and CloudStack in an integrated manner. Additionally, users have the advantage of self-service portals to make changes on their virtual machines and  manage storage.

The PaaS layer, the open-source-based PaaS infrastructure is on the rise in the last 1-2 years. PaaS infrastructure supports the framework based on the Open standard by adapting various development languages (Java, Ruby, Pyson, and so on).

At the network and data center layers, open source is being deployed as well. For the network layer, SDN (Software Defined Networking) and OpenFlow is on the rise as they manage network configuration automatically. Where as the data center layer is seing the likes of Facebook creating Open Compute Project for more efficient server, storage and data center hardware designs.

NTT Communications provides cloud services by actively adopting these technologies.

Upcoming articles will feature trends and promotion of Open IaaS, Open PaaS and Open Network in Japan.
