Avis Budget Group (ABG), a global mobility solutions leader with brands such as Avis, Budget, and Zipcar, has a footprint across approximately 180 countries with over 11,000 rental locations.

CHALLENGE:

Introduction: 

Avis Budget Group (ABG), a global leader in mobility solutions, was at a crossroads with its complex technical infrastructure. This mix of cutting-edge cloud-native applications and necessary yet-to-be-modernized legacy systems was impeding ABG’s objective to lower operational costs while boosting its web and mobile applications’ performance, security, and reliability. ABG turned to D3Clarity — an AWS Advanced Tier Partner with the AWS Migration Competency, celebrated for its acumen in transitioning legacy systems to the AWS cloud to navigate this challenge. 

Customer Challenge: Navigating a Complex, Multi-Faceted Technical Landscape 

ABG’s situation reflects a common dilemma among large, established enterprises: managing a diverse and intricate technical landscape. This landscape, a blend of advanced cloud-native applications and legacy systems awaiting modernization, posed a formidable barrier for ABG to reach its strategic goals. These objectives were twofold: enhance the company’s web and mobile applications’ performance, security, and reliability and reduce operational costs. 

At the heart of this challenge was ABG’s European e-commerce system. This system comprised over 150 unique web domains, each with specific requirements, rules, and configurations. These were developed by various teams over more than a decade, catering to a European customer base with distinct needs across multiple locations, languages, and countries. Each domain had its own compliance and operational necessities. Reliance on third-party Content Delivery Network (CDN) and Web Application Firewall (WAF) products further complicated the scenario. The legacy CDN and WAF solutions became a financial burden due to high licensing and data transfer costs. More critically, they impeded application performance and were limited by outdated, rule-based WAF logic. Managing domain-specific security rules for this extensive array of domains added to the operational strain, rendering the process cumbersome and inefficient. 

ABG’s goal was to create a robust, secure, and cost-effective system that would improve the user experience for its diverse European customer base and future-proof its technological infrastructure. The company sought to harness the full potential of cloud computing to enhance operational efficiency and agility, modernize applications to minimize technical debt, and reduce reliance on costly licenses from third-party vendors. This ambitious undertaking aimed to transform ABG’s technological framework into a more streamlined, responsive, and economically viable structure. 

Why AWS and D3Clarity? 

ABG chose AWS for its global infrastructure, providing the necessary security and scalability to deploy applications close to end-users, thus enhancing performance and reducing latency. D3Clarity was selected for its proven track record with Fortune 500 clients, particularly in data and cloud engineering services. Known for reliability in project management, D3Clarity’s expertise in database migration and web application security was crucial for this project. The urgency to decommission ABG’s on-premises system before license renewals made D3Clarity’s understanding of ABG’s legacy technology and AWS’s next-generation solutions invaluable.

SOLUTION:

What we delivered:

ABG’s solution included secure, private network connections via AWS Direct Connect redundant links and a transit network. Application Load Balancers (ALB) were set up for each application, configured to accept requests only from CloudFront, with added security layers for request validation. Terraform and AWS CloudFormation automated the entire architecture for precision and efficiency. 

ABG leveraged the AWS Migration Acceleration Program (MAP) for a seamless transition. This comprehensive program entailed an Assess Phase for thorough analysis, a Mobilize Phase for translating and validating existing WAF rules and CDN logic, and a Migrate & Modernize phase for the production deployment. Through this structured approach, ABG adeptly employed automated infrastructure-as-code techniques. This enabled the efficient configuration, validation, and migration of over 150 domains, each equipped with tailor-made AWS WAF rules, CloudFront Functions, and Lambda@Edge tasks, all achieved within a remarkably short timeline. 

A comprehensive logging, troubleshooting, and alerting system was implemented to ensure real-time issue resolution. CloudFront, WAF, and ALB logged data securely to Amazon S3, with Amazon Athena for efficient data querying. Amazon QuickSight provided interactive dashboards for traffic data visualization, complemented by Amazon CloudWatch Alarms for real-time monitoring. 

 

How we delivered:

The Process: Leveraging AWS MAP for a Successful Migration 

D3Clarity’s approach to ABG’s migration project was methodically structured around the AWS Migration Acceleration Program (MAP), ensuring a comprehensive and efficient transition to the cloud. This multi-phased approach was critical in addressing ABG’s infrastructure’s unique complexities and scale, particularly the 150+ uniquely distinct domains and their associated ecosystems.
The use of MAP also opened substantial AWS partner co-funding, which D3Clarity passed on to reduce ABG’s migration costs substantially. 

Assess Phase: Laying the Groundwork for Transformation 

Business Case and Metrics: The initial phase involved developing a detailed business case, focusing on the strategic and financial metrics underpinning the migration. This assessment allowed for a clear understanding of the potential return on investment and set a benchmark for evaluating the project’s success. 

In-Depth Analysis of Requirements: A thorough investigation of both business and technical requirements was conducted for each of the 150+ domains. This exhaustive analysis was crucial to understand each domain’s unique characteristics, dependencies, and operational nuances. Mapping these elements was essential to design a migration strategy that would modernize and optimize each domain’s functionality and performance in the cloud environment. 

Mobilize Phase: Preparing for the Transition 

Translating and Validating Legacy WAF Rules and CDN Logic: A significant part of the Mobilize phase was dedicated to translating and validating the existing legacy WAF rules and CDN logic. This process ensured that the security and delivery mechanisms would be seamlessly adapted to the cloud infrastructure, maintaining the integrity and performance of each domain. 

Automation: D3Clarity focused on automating these components, which was critical in streamlining the migration process and minimizing potential disruptions due to human errors or inconsistencies during the transition. 

Migrate & Modernize Phase: Implementation and Empowerment 

Production Operations Documentation and Training: As part of the move to AWS, comprehensive documentation of the new production operations was created. Training sessions were conducted for ABG’s production operations team, which equipped them with the necessary knowledge and skills to effectively manage the new cloud environment. 

Assistance During and After Go-Live: D3Clarity provided extensive support during the go-live phase of the migration, ensuring a smooth transition with minimal operational impact. Following the go-live, ongoing assistance was offered to help ABG’s team adapt to the new systems, address any post-migration challenges, and optimize operations in the new cloud environment. 

Through the structured and strategic use of AWS MAP, D3Clarity ensured that ABG’s migration project was not just about moving to the cloud but also about transforming the way ABG’s digital infrastructure supported its business goals. This careful, step-by-step process facilitated a successful migration, modernizing ABG’s technical landscape while aligning it with its broader objectives of efficiency, security, and scalability.
