London’s Heathrow Airport has been an international travel and trade hub since 1955 and is one of the world’s busiest international airports. In recent years £11 billion has been invested in improving Heathrow Airport, including the opening of the new Terminal 5 in 2010 and the Queen’s Terminal (Terminal 2) in 2014. In 2019, the total number of passengers year was just under 80.9m.

Working as a trusted partner since May 2005, the Redcentric cloud team had already delivered a number of significant platform and software technology refreshes. These included:

  • Airport website, hosted, managed and supported under SLA’s of 99.95% availability and protected by DDoS and Intrusion Protection Services.
  • Flight Information Hub (FIHub), a single point of truth for passenger focussed flight and travel data
  • Amazon Alexa Skill, giving passengers access to flight information via this exciting interface
  • Android based Passenger Connections kiosk which was trialled in Terminals 2 and 3 and remains live

Heathrow’s Flight Information Hub, which had been providing real-time passenger information since 2015, was approaching the end of its life. It was increasingly difficult to enhance and modernise.

Heathrow needed a modern, effective replacement to this critical system that:

  • Reduced hosting costs
  • Improved functionality
  • Increased solution flexibility and scalability


How Redcentric helped:

A new system was designed which would be built on Microsoft Azure.

Key features of the new solution included:

  • Native cloud functionality
  • Multi-region deployment, running in an active-active state for resilience
  • Proactive monitoring, using real time alerts and dashboards
  • Synthetic traffic, for active monitoring and validation of application real-time behaviour
  • Serverless code deployment, to support rapid scaling under load and eliminate underutilised infrastructure provisioning
  • Azure COSMOS DB, for resilience, scalability and global data replication using an eventual consistency model
  • Self-Recovery, to detect data inconsistencies and initiate automatic recovery
  • Provision of RESTful APIs via Azure API Management
  • A fully documented self-service developer interface
  • Integration and processing of data from multiple sources
  • The merging of three different flight data sources, to get the passengers’ viewpoint
This was an easy one as Redcentric have acted with a competent, proactive approach exhibiting a ‘can do’ attitude throughout the engagement. It’s always a pleasure to do business with a professional engineering team.

Business benefits

The new platform was launched in May 2020. All subscribers were migrated and all legacy systems were decommissioned by July 2020.

Key benefits included:

  • Reduced costs – reduced hosting costs by 85%, managed service costs by 35%, overall Opex costs reduced by 64%
  • Scalability – proven to meet the demand of passenger and operational subscribers
  • Integration – eased integration for new subscribers
  • Future-proof – a foundation for future use-cases, including customer data feeds for sponsored terminals and off-campus information boards
