IaaS Providers

Japanese IaaS (Infrastructure as a Service) providers rent virtual servers, disks, and networks that you configure yourself, while they run the hardware and data centers. Unlike a virtual private server, these platforms let you link many servers on private networks behind firewalls.

When the physical machine under a server fails, most platforms restart the server on healthy hardware automatically. Pricing is either pay-as-you-go up to a monthly ceiling or a flat monthly fee.

Registered with ISMAP (Information system Security Management and Assessment Program), the national government’s list of security-assessed cloud services. Public agencies refer to it when procuring cloud services.

Two or more regions, meaning data center sites far apart from each other, let you keep a standby copy of your systems that survives a regional disaster.

An API compatible with OpenStack, open-source software for running clouds, so scripts and standard OpenStack tools can create and manage servers, storage, and networks.

Object storage (storage for files organized into buckets) with an interface compatible with Amazon S3, so existing S3 tools and libraries work with little or no change.

GPU servers for work that runs many calculations in parallel, such as training and running AI models, rendering, and scientific simulation.

10 Gbps network links as standard, usually shared and without a guaranteed speed, for traffic-heavy sites and large data transfers.
