Q. How can I use K5?

Currently, K5 is available only through our sales channels. For customers who want to use K5, contact our sales or inquire using the inquiry form.

Q. How much and how fast can it be if we migrate our mission-critical systems to K5?

It depends on the contents and size of your system. The major benefits are speedy development and enhanced productivity as well as integration with external systems and systems with high adaptability to changes.

Q. Regarding quality improvement/acceleration of development, how much improvement is achieved compared with existing solutions?

The results vary depending on the target system, however we reduced development time to 1/3, doubled productivity, and reduced PG size to 1/6. These values are compared with the existing solutions for rebuilding of mission-critical systems as part of building an on-premises development infrastructure service of the mission-critical job, which is one of the features we provide. It is on a case by case basis, but we believe the flexibility of development and operation is significantly improved.

Q. What are the benefits of migration for companies already using existing clouds?

It is very effective when you want to globally optimize a complex set of many clouds that were introduced mainly by on-site departments, or to review service levels of performance, reliability, security, etc. or to require integration with other systems as a result of feature enhancements. Benefits of migrating to our cloud will be greater if you consider it when you integrate operation and maintenance that require more advanced SI elements, or when you integrate clouds with mission-critical systems.

Q. What are the benefits for companies that use Fujitsu hosting?

With integrated managed service including host, operations can be integrated with ease compared with developing individual systems. We plan to provide a service that enables hybrid integration between host and cloud easily, and a data store service that can support disaster recovery.
You can use it as the migration destination for your host assets. By moving host assets to a public cloud, customers can be relieved from host update tasks, and operation and maintenance tasks including those for hardware.

Q. What does "K5" mean?

"K" is the first letter of "Knowledge Integration for Big Change" and "5" represents five continents with globalization of the solution in mind.

Q. What does SE expertise specifically represent and how is it provided?

Some of the expertise provided are: SE tasks, configuration and settings of systems in operation, industry-specific business know-how, and know-how of failure investigation, isolation, and response. They are categorized into three forms of integration pattern, service component, and platform features. They are then implemented and provided as services.

Q. What are the purposes of being OpenStack-based?

It is designed to utilize the expertise of worldwide developers to respond to speedy technological innovations, enhance flexibility of application and system operation with greater compatibility with external OpenStack-based cloud solutions, and respond to diversified needs of the customers.

Q. Where can I check my billing information?

You can check the confirmed billing information using the K5 Portal.
Provisional billing information for the current month can be viewed in the IaaS Portal or the PaaS Portal.

Q. Are features such as DR environment provided in each region where K5 is available?

DR in some regions will be considered in future versions.

Q. Will it be globally rolled out?

It will be rolled out progressively from 2016.


Service Overview

Q. What kind of service is FUJITSU Cloud Service K5 IaaS?

It is a service available for customers to deploy and use virtual resources using the Service Portal/APIs. With this service, virtual systems can be built in a short period of time.


Q. What are billing concepts?

"Pay-per-use" service billed according to usage time/volume. There are no initial costs or minimum usage fee. Refer to the price list for details.

Usage details

Q. Where can I check my usage details?

You can check your usage details in the Service Portal.

Virtual server

Q. What are the user account and password configured when Windows Server was created?

The user name and password at the time when they were issued are related to the service infrastructure, and are not published. Therefore, you need to set and deploy your password in API at the moment.

Virtual network

Q. Firewall/security groups are related to stateful inspection, but are communication responses allowed by Ingress rules communicated regardless of Egress rules?

As you are aware, any communication responses allowed by Ingress rules can be communicated for firewall/security groups. The opposite is also true.

Q. Are there any APIs that can check the global IP address of an external network that was assigned to a virtual router? Are there any APIs that can check the IP address of an external network after NAT was performed for the source IP address?

FQDN is used so that API operations by users and administrators, and increase, decrease or changes of external IP using autoscaling that will be implemented are transparent. Therefore, external IP address of the router, and external IP address after NAT conversion are not published.

Q. Is there any feature that supports dynamic port application?

Connection tracking feature is not provided for individual application that uses different TCP/UDP port from that of the initial connection.

Q. Which processing is performed for a virtual router first? NAT processing or filtering (firewall feature) processing?

NAT IP conversion process is performed first, and then firewall filtering is performed using the generated IP.

Q. Is there any method that allows intranet communication between projects in K5?

Global IP addresses can be used for communication between projects.

Q. We would like to use two subnets for a virtual network within a project. We confirmed that the upper limit of 10 subnets per project has not been reached, but the HTTP/1.1 409 Conflict error occurs.

By definition, it is specified that one virtual network corresponds to one subnet, so the same number of virtual networks as that of subnets need to be created if multiple subnets are required.

Load Balancer

Q. When distributing loads between SSL-TCP and TCP-TCP, which device is used for the source IP address used for communicating from the load balancer to distribution destinations?

The IP address for the load balancer is used as the source IP address when communicating with the distribution destinations whether SSL-TCP or TCP-TCP is used.

Q. An error occurred when I tried to configure multiple listeners with different InstancePort and Protocol for one load balancer. Is it required by specification that all listeners have identical InstancePort, Protocol, and SSLCertificateId to be able to configure multiple listeners?

You can specify only one protocol and one port to be used for transfer to a virtual server. Therefore, any communication that configures multiple ports is not supported.


Q. Is a time synchronization destination server (NTP server) available as a K5 server?

No NTP servers are currently available. We are considering whether to offer this feature in future versions.


Service Overview

Q. What kind of service is FUJITSU Cloud Service K5 CF?

It is PaaS based on the open source standard Cloud Foundry. As an application execution environment is provided, customer applications can be quickly built.
