  Internet services provider IIJ operates some of the largest network and server infrastructure in Japan. Here, we report on Internet trends over the past year based on information obtained through the operation of this infrastructure.

  On October 1, 2021, IIJ launched IIJ GIO Infrastructure P2 Gen.2 (P2 Gen.2 for short), a new IaaS that fully combines and takes advantage of the characteristics of the public IaaS and private IaaS developed and provided under the IIJ GIO brand.P2 Gen.2 is a new-generation IaaS designed to confer the full benefits of public clouds while also taking advantage of VMware vSphere-based private clouds.This report looks at the development of the P2 Gen.2 service and the ideals and reality of its operation in the field with a focus on the network.

• Focused Research (2) "In Pursuit of Carbon Neutrality in the Data Center"[11.1MB]

  Over 120 countries have declared their intention to achieve carbon neutrality-achieve zero greenhouse gas (CO2,methane, N2O, chlorofluorocarbons [CFCs]) emissions-by 2050, a goal of the international climate change treaty known as the Paris Agreement. The Japanese government also declared its 2050 carbon neutrality goal in October 2020.
  And in the Green Growth Strategy it unveiled in December 2020, it set goals for a wide range of industries, with the following goals being laid out for data centers.

  • By 2030, all newly constructed data centers should consumer 30% less energy and be partly powered by renewable energy
  • Aim for carbon-neutral data centers by 2040

  Below, we go over our energy-saving initiatives at Matsue DCP and Shiroi DCC, where we have achieved strong energy-saving performance, and we round out the discussion by presenting a reference model for carbon neutrality in the data center.

• Focused Research (3) "IIJ's Road to BCR Approval-Complying with EU GDPR and Beyond"[455KB]

  In August 2021, we received notice of the long-awaited approval for IIJ's BCRs (Binding Corporate Rules) from LDINRW, the supervisory authority in North Rhine-Westphalia(NRW), Germany. Since the EU's GDPR (General Data Protection Regulation) came into force, 18 companies worldwide have received BCR approval (as of August 2021), IIJ being one of them. The five years since we started looking at BCRs as a means for complying with the GDPR have been eventful, and with the approval, we can now proudly say that our efforts so far have finally been recognized. Here, I discuss why we chose the IIJ BCR approval route, what the road to acquiring that approval was like, and where we are headed from here.
