München: Cyber Security Fatigue

Cybersecurity ist längst kein reines IT-Thema mehr – sie betrifft das gesamte Unternehmen. Doch während die Bedrohungslage zunimmt, geraten viele Security-Verantwortliche an ihre Belastungsgrenzen: zwischen 24/7-Verantwortung, wachsenden Anforderungen und dem ständigen Innovationsdruck.

Köln: CIO & CISO, das Rezilienz-Power-Duo

IT-Betrieb und Cybersicherheit stehen heute unter extremem Druck: steigende Komplexität, wachsende regulatorische Anforderungen (NIS2, DORA, KRITIS), chronische Ressourcenknappheit – und gleichzeitig eine Bedrohungslage, die keine Verzögerungen duldet. Trotzdem agieren viele IT- und Security-Teams noch immer in Silos. Die Folge: ineffiziente Abläufe, Tool-Wildwuchs, langsame Reaktion auf Vorfälle und unklare Verantwortlichkeiten.

Les Rencontres: La dette technique : Un défi stratégique pour les entreprises

La dette technique est comparable à la négligence des réparations d'une maison. Ignorer un toit qui fuit peut faire gagner du temps aujourd'hui, mais cela pourrait conduire à l'effondrement du plafond plus tard. Pour remédier à la dette technique, il faut trouver et réparer ces fuites dès maintenant et mettre en place un plan d'entretien de la maison afin qu'elle soit prête pour les extensions futures. Pour résoudre ces problèmes, il faut définir des priorités stratégiques, communiquer clairement avec les parties prenantes et établir une feuille de route à long terme pour la modernisation. Cet événement se déroulera entièrement en français.

A modernization journey with zero downtime

Carey International's aging on-premise systems struggled to meet growing demands for security, high availability, and cost efficiency. Carey migrated its applications to a cloud-based architecture using Red Hat OpenShift® in AWS (ROSA) and IBM WebSphere Liberty container platform. They also adopted IBM Instana for real-time monitoring and proactive maintenance.

 
Legacy limitations and the need for change
 

Carey International, Inc.—a storied name in the premium ground transportation industry—has been redefining luxury travel since the 1920s. Its sprawling operation comprise a robust network of subsidiary, franchise and affiliate partners across 400 cities worldwide. With a staggering record of 550 thousand trips in 69 countries in 2022, its centralized reservation, billing, customer service and event management systems represent a complex backbone of operations that demands relentless uptime and security. However, dated legacy systems faced modern pressures, prompting Carey to embark on a transformative journey of application modernization.

Navigating a veritable minefield of operational challenges, Carey's legacy systems—sprawling across a mix of traditional platforms including IBM® WebSphere® Application Server Network Deployment, Red Hat® JBoss® Enterprise Application Platform and Oracle databases—began to strain under customer demands for enhanced security, the need for high-availability services, and rising costs—all exacerbated by the specialized skills required to maintain these aging technologies. The tipping point came with the realization that its systems could not keep up with a swiftly changing digital landscape without significant operational risk and unforeseen expenses.

 
 
Adopting cloud fluency with IBM WebSphere Liberty
 

Carey's strategic move to cloud architecture, specifically Red Hat OpenShift® in AWS (ROSA), marked a paradigm shift towards agility and scalability. By transitioning its Java® applications to the IBM WebSphere Liberty container platform, Carey embraced a seamless, efficient system capable of meeting the needs of an operation that never sleeps. Alongside, Oracle databases moved to Oracle Cloud Infrastructure and APIs were elegantly managed, demonstrating how modern containerization and cloud-native services could refurbish even the most deeply rooted systems.

The introduction of IBM Instana® to Carey's tech stack was pivotal. Legacy applications became transparent under the IBM technology’s fully-automated real-time observability platform. Instana provided Carey with the X-ray vision to pinpoint performance bottlenecks, resource anomalies and operational issues in real-time, ushering in a new era of reliability and proactive maintenance.

The final leap into modernized operations was a meticulously planned cutover—a testament to Carey's all-in commitment to modernization. With thorough documentation and practice runs, the team executed a smooth transition. Carey has experienced nearly zero unplanned or planned downtime since the migration. Performance and reliability numbers have met and often exceeded those for the on-premise system.

 
The measure of success in a modernized infrastructure
 

In the wake of these sweeping changes, Carey now boasts an architecture that not only competes with but surpasses the on-premise performance metrics of yore. Zero downtime has become the new standard, and the nimble, rolling release process signifies a newfound operational agility. As Carey continues to fine-tune its system and explore further cost optimizations with Red Hat and AWS, the narrative is clear: application modernization elevates service capabilities, bolsters security and ensures a company's relevance in today's dynamic tech environment.

Carey's journey to application modernization with WebSphere Liberty and Instana is more than a case study of technological upgrade—it is a celebration of timely transformation, matching the pace of an ever-evolving industry while laying a sturdy, future-proof foundation for the legacy of luxury travel.

IBM, Red Hat and AWS were a great team and provided hands on assistance to ensure project success. IBM Instana was key to quickly identifying problems and their root causes as well as critical to monitoring Red Hat OpenShift during load testing, go-live and in production. All applications were migrated in May 2023 during a six-hour outage window. To date, performance and reliability exceed the on-premise system. Releases into the cloud platform are simple, fast and non-disruptive. Development pipeline processes are also greatly streamlined.
