DXC Technology ensures 24x7 operation of 1,000 servers
All Nippon Airways (ANA) needed help managing its complex open systems infrastructure to ensure high availability of critical systems so it chose DXC as an outsourcing partner. As a central member of the dedicated team for open systems operations, DXC now supports the ANA Group’s continued progress 24 hours a day, 365 days a year.
Move to open systems
The aviation industry has entered an era of global competition. All Nippon Airways (ANA), a member of the Star
Alliance Network, has increased its number of international flights in response. It has developed a multi-brand
strategy of both full-service and low-cost flights. ANA is also known for its world-class reliability as a carrier
and continues to outclass other airlines on a variety of points, including service quality, on-time arrival rate,
in-service rates, and safety.
The group’s continued progress is based on efficient IT services, including its open systems. ANA began the migration
of its principal systems from mainframes to open systems ten years ago. Currently, approximately 80 percent of its
systems – from passenger, cargo, and maintenance services to its online reservations – are running in open
environments like UNIX®, Linux, and Windows®.
“Moving to open systems resulted in an increase in service provision speeds but we were faced with new issues, like
how to operate those open systems,” recalls Yukihiko Sasaki, Managing Director, Portfolio Management, Innovation & IT
Strategy, All Nippon Airways Co., Ltd.
Operations team members were so busy dealing with problems that they didn’t have the time to actually work on
improving the operational process itself and implement measures to avoid reoccurrence of incidents.
“We decided that it would require too much time to remedy the situation on our own and began to seriously consider
seeking the assistance of a specialist with large-scale open systems operations know-how,” notes Sasaki.
Outsourced infrastructure
The IT Services Unit, now the Business Process Reform Unit, reversed its policy of fully in-house operations and
decided to make use of outsourcing services.
At the time, the IT subsidiary’s Infrastructure Operations Division was overseeing operations of approximately 80 ANA
open systems that contained a total of 630 servers. This was a multi-vendor environment, consisting of a mix of
hardware, middleware and operating systems. The outsourcer would obviously need to have large-scale open systems
operations know-how and it was decided that experience with IT Infrastructure Library (ITIL) procedures would also be
a requirement.
“In order to improve operational quality, just responding to the events at hand wouldn’t be enough. We needed to
continue to improve the operational process while anticipating events that might occur in the future. To do this, it
was necessary to implement ITIL, with its provisions for continued improvement of operations,” comments Sasaki.
Proposals from multiple outsourcers were considered, but in the end ANA chose to partner with DXC, mainly because of
its technological competence. “DXC had played an important part in our move to open systems so we had
already seen the high level of skill displayed by DXC technicians,” says Sasaki.
“DXC also had a proven track record of providing ITIL compliant operations outsourcing services to customers
around the world.”
ANA entered into a five-year infrastructure operations outsourcing contract with DXC. At the same time, it
established a team of open systems operations specialists called the Open Systems Maintenance Center (OMC). This
system of operations between the IT subsidiary company and DXC staff was designed to operate 24 hours a day, 365 days
a year. Operations of existing systems were transferred to OMC in batches.
Increased availability
The mission of the OMC is to ensure stable operations of a large-scale open systems infrastructure. This involves a
wide variety of tasks, including operations monitoring, fault management, configuration management, response inquiry,
reporting, and more.
“Building a framework from which to approach operations was the starting point for improving the operational
process,” comments Kiyokazu Kataoka, a member of the Infrastructure Maintenance team. “In the past, there was no
clear set of procedures for operations, so there weren’t many standards to aim for even if you wanted to make
improvements. DXC redefined all of our operational processes using DXC best practices, which are
ITIL compliant.”
We’re always looking forward to new ideas from DXC and with service support like this, our goal should be worldwide-leading operational quality. We want DXC at our side as we boldly take on challenges that others couldn’t even consider.
“Being able to visualize the effects made it possible to test hypotheses regarding operational process improvements. We had established a Plan Do Check Act (PDCA) cycle,” adds Kataoka. “By analyzing incident records and understanding the sources and mechanisms of problems, we were able to begin predicting where problems might occur next and respond appropriately,” explains Kataoka.
Building a knowledge base about the circumstances of past problems and resolution procedures also resulted in less time spent on problem resolution.
Drawing on DXC best practices to implement these measures resulted in massive improvement in operational quality of ANA open systems. Currently, over 100 open systems and 1,000 servers are overseen by the OMC. Critical system failures leading to service downtime has been reduced by 82 percent. Incident numbers per server have also fallen dramatically. A high availability of 99.997 percent has been achieved for mission-critical systems, like the reservation systems and the flight operations systems which are dependent on on-time arrival rates.
The OMC ended its first-stage five-year contract one year early and is currently under a second-stage contract. “Incidents that affect customer service were on a downward trend in stage one, but still hadn’t reached zero. In stage two, we wanted to achieve even higher operational quality in a short period of time,” notes Sasaki.
In addition to increased quality, cost reduction was once again an important theme in stage two. In order to pull ahead in the global market, it was necessary to reduce fixed costs, even for IT operations. After surveying the IT operations outsourcing situation in various industries, Sasaki and his team decided to make “global cost- competitiveness within five years” a requirement.
It was a difficult requirement to meet, but in the end DXC delivered and was chosen once again. “Of course DXC's proposal was excellent, but that wasn’t the only reason. We also considered the high level of motivation and on-site capability that DXC technicians had shown up until then. When it comes to operations, practical ability in the field is critical,” explains Sasaki.
With 24 hours a day, 365 days a year operations, communication and relations between team members can’t be ignored. When an incident occurs, rapport and teamwork are put to the test. The DXC team members are not only technologically proficient, but also displayed excellent interpersonal skills. “In the field, it doesn’t matter who belongs to which company. Both the high motivation of the members and the improvement of operational quality are connected to having worked together with the same sense of mission – supporting a social infrastructure. We look forward to achieving even greater improvements in stage two, together with team members that we trust,” says Sasaki. He then went on to sum up with the following:
“We’re always looking forward to new ideas from DXC. Our goal should be worldwide leading operational quality, with the service to support this. We want DXC at our side as we boldly take on challenges that others couldn’t even consider.”
The ANA Group aims to be the world’s leading airline, and DXC continues to help support the open systems infrastructure that provides a foundation for that challenge.
