‘Biting the bullet’
Cathay Pacific’s journey towards the cloud may be a bold move but it wasn’t without its challenges, revealed Fong. Currently some 40% of the airline’s workload is on the cloud but in the early days, it had concerns over security and privacy issues, Fong (pic, right) shared.
“The biggest risk for us was that the cloud wasn’t secure or reliable, at least perception-wise,” he explained. “The old thinking was that if you can’t see it, you can’t control it, and we experienced push back. And technical people were concerned whether we would have trouble moving our technologies to the cloud easily or not.”
Fong said in the end, the company did its due diligence as best as it could, “bit the bullet,” and initially migrated small workloads to the cloud. Eventually, it moved more critical workloads while becoming more comfortable in doing so.
Asked if Cathay Pacific has a return-on-investment (ROI) goal, Fong said, “Our goal wasn’t about ROI but about availability and reliability.”
Quizzed as to what lessons the company learnt from moving to the cloud, Fong said his team had to learn to shuffle resources and organise themselves into vertical development teams, which he explained involved becoming more product- rather than project-focused.
“Every team needed to be vertical – from the user experience and interface, development and platform to infrastructure, operations and maintenance – every one needed to focus on the technology stack and development lifecycle.
“Additionally, by using cloud, we adopted a devops and agile methodology to help us to speed up the whole development lifecycle,” Fong explained.
Asked if any staff were affected by these changes either in terms of roles or reduction in headcount, Fong said the team did not cut any resources and had the same number of people in it but that they just had to do things differently.
“By going into the cloud with AWS, we had to change our mindset, training and culture from a waterfall towards a devops thinking.
At the end of the first phase of its transformation, Fong claimed that Cathay Pacific’s customers began noticing the changes in that everything from the apps and web services were more stable, they didn’t crash as much as before and the performance was faster. New products were also rolled out much more quickly, especially those that enhanced customer experiences.
“We significantly improved our stability and availability, as we experienced almost zero down time,” he claimed. “Our time-to-market also improved and our development lifecycle costs reduced by 67%. Other costs such as operational and project development costs reduced by half.”
When asked if Cathay Pacific would hold back migrating some sensitive workloads such as financials to the cloud, Fong was bullish, noting that they plan to move as much as they can onto the cloud, although he conceded that not all workloads could be migrated due to the legacy nature.
“Actually, our financials are already in the cloud and we’re comfortable with that,” he said. “We plan to move more onto the cloud and use more services from AWS and other cloud players as they roll out their features.”
On what kind of features it plans to use, Fong said the airline is closely watching the newly launched Amazon Elastic Container Service for Kubernetes (Amazon EKS) as well as multiple master copy database, and machine learning features from the cloud vendor.
“Fraud detection and prevention is typically where machine learning can be used,” he said, adding that the airline is doing a proof of concept with AWS.
“Some cases we may get a ‘customer’ logging on from a Russian IP address and buying a ticket using an American credit card that goes from Bangkok to Hong Kong, for a Japanese national. Or someone who purchased a ticket 24 hours before departure under suspicious means.
“These are but a few scenarios which have distinct patterns which is a challenge for us now. We feel machine learning will be able to help learn these patterns and help us make the right decisions.”
