Programme context
easyJet describes a former operating model in which teams could see that a fault existed but could not reliably isolate it across the application, middleware, database and network layers. The airline adopted AppDynamics and ThousandEyes while continuing a wider move toward cloud infrastructure and SD-WAN.
Why this matters: The record captures a live, multi-layer observability platform without converting the airline's wider cloud and network roadmap into a completed transformation.
Observability timeline
| Date or stage | Milestone | What changed | Evidence status |
|---|---|---|---|
| Initial adoption | AppDynamics operational | easyJet began monitoring and load-testing easyjet.com and extended visibility through applications, databases and infrastructure. | Confirmed |
| 2019 | easyJet holidays relaunch | AppDynamics supported monitoring and optimisation of the bounded holidays-platform relaunch. | Confirmed |
| Later expansion | ThousandEyes added | Network and SaaS visibility was integrated with application observability for end-to-end fault isolation. | Confirmed |
| Continuing | cloud and network transformation | AWS migration, SD-WAN adoption and further observability improvement remain active. | Underway |
Workload transition matrix
| Workload | Previous constraint | Observability destination | Status |
|---|---|---|---|
| easyjet.com and easyJet holidays | performance risk under peak customer demand | Splunk AppDynamics | operational |
| crew-management and rostering services | fault source difficult to isolate across dependencies | AppDynamics and ThousandEyes unified view | operational |
| network and SaaS services | limited end-to-end network-edge visibility | Cisco ThousandEyes | operational and expanding |
| AWS and SD-WAN estate | on-premises and home-grown network dependencies | cloud and software-defined network model with integrated observability | underway |
Implementation and architecture
- AppDynamics provides application, database and infrastructure visibility and supports pre-peak load testing.
- ThousandEyes extends insight across network performance and SaaS cloud solutions.
- The combined view is used for critical crew-management services and supports faster isolation of cross-layer faults.
Known unknowns and contradictions
- The customer-story page does not state its publication date or one programme start date.
- The source does not enumerate every monitored application, retained monitoring product or network dependency.
- The 2019 easyJet holidays launch is not the completion date for the full observability programme.
- The AWS migration and SD-WAN transition remain active rather than complete.
No missing fact is inferred to broaden the source-supported event.
PlatformTrace analysis
Splunk’s customer evidence supports operational full-stack observability and the named workload outcomes. It does not prove that every easyJet application is instrumented, every previous monitoring or network tool is retired, or the wider AWS and SD-WAN transformations are complete.
Improved fault isolation, availability and resolution outcomes are recorded as source-reported operational results rather than independently audited universal performance claims.
PlatformTrace includes this record because easyJet plc is UK-based. The cited source describes named enterprise workloads but does not geographically partition them between the United Kingdom, Ireland or other operating markets. No global estate-wide completion is inferred.
