PostNL, the largest logistics company inthe Benelux region, has embarked on a remarkable journey towards a fully serverless architecture, abandoning traditional infrastructure like EC2 and Kubernetes. This shift, driven by acommitment to internal product delivery and a 100% cloud strategy, has yielded significant benefits in terms of efficiency, responsiveness, and cost optimization.
From Outsourcing to Internal Expertise
PostNL’s transformation began with a strategic decision to bring software delivery in-house, moving away from reliance on off-the-shelf products. This required building a robust internal software delivery capability, whichinvolved establishing clear guidelines and best practices.
Luc van Donkersgoed, PostNL’s Chief Engineer and an AWS Serverless Hero, outlines the company’s approach: a fixed, flexible, free model for technology,products, and services. This framework provides a balance between standardization and team autonomy.
Embracing Serverless on AWS
PostNL strategically chose AWS as its public cloud provider, committing to a purely cloud-native approach, particularly embracing serverless services. This led to the creation of a dedicated AWS platform team,the Cloud Center of Excellence (CCoE), to guide engineering teams in leveraging AWS services while discouraging the use of non-preferred services like EC2.
The decision to adopt serverless was driven by the highly variable nature of PostNL’s application workloads, including daily and weekly patterns, and the surge in usage duringpeak seasons like Black Friday and Valentine’s Day. AWS’s serverless stack, with its elastic pricing, effortless scaling, and cloud platform capabilities, proved to be the ideal solution for these challenges.
Leveraging DynamoDB’s Auto-Scaling
PostNL’s experience with DynamoDB, afully managed NoSQL database, exemplifies the benefits of serverless. DynamoDB’s automatic scaling capabilities have been instrumental in handling fluctuating workloads, ensuring consistent performance even during peak demand periods.
The Benefits of a Serverless Architecture
PostNL’s serverless journey has yielded several significant benefits:
- Increased Efficiency: Serverless architecture has streamlined development and deployment processes, allowing engineers to focus on core business logic rather than managing infrastructure.
- Enhanced Responsiveness: The ability to scale resources on demand has enabled PostNL to respond quickly to changing business needs and market dynamics.
- Cost Optimization: Serverless pricing models,based on actual usage, have significantly reduced operational costs compared to traditional infrastructure.
A Model for Cloud-Native Transformation
PostNL’s success story serves as a compelling case study for organizations seeking to embrace cloud-native technologies. By adopting a strategic approach, leveraging serverless solutions, and fostering a culture ofinnovation, PostNL has achieved remarkable results, demonstrating the transformative power of serverless architecture in the modern digital landscape.
