With prices like $6.23 (€5.76) for a one-way fare from London to Strasbourg, it’s no wonder that more than 1.3 million people visit the Ryanair website every day. For Declan Costello, infrastructure and operations manager at Ryanair, the website is one of his team’s top priorities. After all, if something isn’t working correctly on the Ryanair site, passengers can’t book flight segments, check in for flights, rent cars, or print boarding passes.
Not too long ago, Declan and his team had little insight into performance and troubleshooting for the website. By looking at load times for webpages, the team of four responsible for the site could tell that something was wrong but not much else. "We knew the site had slowed down or stopped, but we didn’t have a clue where the problem was, nor did we have the data to figure it out," he says.
The Ryanair website interfaces with the company’s own backend systems as well as third-party services such as those for car rentals, hotel booking, parking, and other travel offerings that Ryanair also sells. So when something happened anywhere in that ecosystem, Declan’s team had to try to deduce what was happening. "We’d go into a frenzy and start testing the site to try to figure out which page was slowing everything down or erroring out or timing out," explains Declan.
Getting real-time data, every second of every day
An architect on Declan’s team heard about New Relic and decided to test it on the Ryanair mobile website. New Relic passed the test with flying colors and Ryanair quickly deployed it on the main website as well. It soon became the single source of performance data for not only Declan’s team, but across IT and the business.
"We turned off the other monitors we were using because New Relic is our single, global source of truth for the website," says Declan. "I use New Relic every minute of every day."
One wall of the Ryanair office shows New Relic real-time dashboards on nine different screens. Besides operations, all of the developers at Ryanair also have access to New Relic. Declan explains that "every environment is fully instrumented in the same way as our production environment, all the way through development, integration, user acceptance testing, pre-production, staging, and production environments."
What is everyone watching when they look at the New Relic dashboards? The top metric across the company is the number of seats or segments sold. "Everyone watches that number, from the commercial yields team to the C-suite," says Declan. "They’re watching it day in and day out on their mobile phones and one executive has it on his wall."
Before New Relic, getting that figure required taking data from an email that came from the backend booking engine every 30 minutes and then entering the figure into a spreadsheet. "Someone would build that spreadsheet hour by hour throughout the day." says Declan. Now, the information is available at a glance in real time.
Beyond troubleshooting
In addition to segments sold, Ryanair tracks many other metrics including online check-ins, flight availability searches, payment response times, new MyRyanair account signups, failed logins, payment approval rates, error rates, and more across both the main website and the mobile. These metrics help Declan’s team and the broader business:
- Uncover trends and patterns: Ryanair can quickly and easily compare metrics over different time periods. "For example, we can see that both our number of seats sold and check-ins dipped at the same time on the same day last week," says Declan.
- Identify performance issues with third-party services: Whether it’s a bank with slow approval time for credit cards, a faulty IP address at PayPal, or a booking engine for a car rental company causing slow calls, using the New Relic Query Language (NRQL), Declan’s team can ask a series of complex questions in rapid succession about the system, and quickly build context and iterate until they discover clues about where the problem might lie.
- Detect cyberattacks: Screen scrapers that can slow down overall performance are a huge problem for Ryanair, but New Relic helps the operations team track screen scrapers and ensure the company’s anti-scraping technology blocks the cyberattack.
- Discover increases in payment fraud attempts: Tracking the percentage of payments pending versus approvals helps Ryanair identify increases in fraud attempts or unintended consequences of changes to fraud detection technology. This is one area where Declan relies on New Relic NRQL alerts to notify his team when payment metrics surpass thresholds.
We turned off the other monitors we were using because New Relic is our single, global source of truth for the website.
A faster, scalable, and more self-sufficient team
Thanks to the New Relic, Declan believes that his operations team is more self-sufficient. Rather than relying on a software architect to tell them which particular part of the site or which third party was at fault, the team can monitor performance and diagnose problems in real time. "New Relic has made us all better and faster at doing our jobs," says Declan.
It has also enabled the Ryanair IT operations team to take on far more responsibility and support more customer-facing infrastructure with the same small group of four people. "Before we had just one website to monitor, but now we have five websites with nine different microservices all interlaced and talking to each other within the website," says Declan. "Without New Relic, it would be impossible to troubleshoot this environment."
Now with New Relic, the Ryanair website can continue delivering on the company’s motto ‘Always Getting Better’, with full-stack visibility and digital intelligence that delivers an improved customer experience.
