Citrix NetScaler provides resilient agility for Ryanair’s website

Ryanair’s booking engine ryanair.com is critical to the business. The site and app experienced 1 billion visits in 2018. Ryanair works closely with Zinopy which supplies Ryanair with its Citrix technology.

Challenge

Ryanair’s website is absolutely critical to the company, so stability and resilience are vital. Without it, the company would have planes to fly but no passengers. As well as handling very high volumes of traffic, the website experiences significant spikes in demand and needed to continue to do this as the airline expands, adds new routes and grows customers.

Solution

Ryanair uses NetScaler’s Global Server Load Balancing (GSLB) functionality to manage load-balancing within each data centre. so that traffic can be shared across all three, reducing the number of servers required.

When a marketing promotion requires a dedicated URL or to re-direct an existing address, the team quickly accommodates this using NetScaler’s custom re-write and responder-rules in just 20 minutes. This that might otherwise take two or three hours of developers’ time.

Typically, Ryanair’s data centres are configured as one active, one passive and one spare. When deploying changes to the website, the team uses NetScaler to switch between data centres or between banks of servers, enabling updates to be made in an agile fashion, with no site downtime, whilst always having a roll-back version as back-up.

client perspective

" Without the website we may have planes ready to fly but would have no paying customers. Therefore, stability and resilience are vital. As well as handling very high volumes of traffic, the website also experiences significant spikes in demand during promotions. "
