Migrating a Global Publishing Platform to AWS
Overview
A global magazine publisher needed to consolidate a complex and fragmented digital estate into a single modern publishing platform.
The organisation operated a large portfolio of magazine brands, websites, content systems, and regional editorial workflows. Over time, this had created a difficult technical environment to manage. Different brands relied on different CMS platforms, legacy hosting arrangements, and inconsistent publishing processes.
Vesper supported a major AWS-based platform migration, helping the client move away from fragmented legacy systems and towards a unified publishing infrastructure that could support scale, editorial speed, and future product innovation.
The Challenge
The client’s digital estate had grown across multiple brands, markets, and technology stacks. This created operational silos and made it difficult to maintain consistent editorial workflows, user experiences, and platform performance across the organisation.
The existing environment also placed pressure on engineering and platform teams. Maintaining multiple CMS systems and hosting setups created unnecessary complexity, while high-traffic periods exposed the limitations of legacy infrastructure. The client needed a more resilient and scalable foundation that could support large audience volumes without increasing operational overhead.
The migration itself was also complex. Content, assets, metadata, and publishing workflows needed to be moved from different legacy systems into a single modern platform. The process had to be repeatable, testable, and controlled, with careful planning around production cutovers and rollback.
The Solution
Vesper developed a custom migration approach to support the move to a modern AWS-based publishing platform.
The work centred on a repeatable migration tool that could extract content and assets from legacy CMS platforms, transform that material into the new platform schema, and load it into the unified publishing environment. This gave the client a structured way to migrate large volumes of content while reducing manual effort and delivery risk.
The migration process was designed to work in stages. Content and metadata could be pulled from source systems, cleaned, normalised, tested, and validated before being moved into production. This helped the team identify issues early and gave stakeholders greater confidence in each migration wave.
Vesper also supported automated testing, deployment workflows, production cutover planning, and rollback processes. The goal was not simply to move content from one system to another, but to create a more maintainable migration capability that could support a large publishing estate at enterprise scale.
Technical Delivery
The platform migration was delivered using a modern AWS architecture designed for scalability, repeatability, and resilience.
Containerised migration workloads ran on Amazon EKS, supported by Amazon EC2 worker nodes for scalable processing. Amazon RDS for PostgreSQL was used as a central repository for content data during the migration process, while Amazon S3 provided secure asset staging and backup. AWS Lambda supported metadata enrichment and one-off transformation tasks.
The delivery process also included CI/CD pipelines for automated ingestion, testing, and production deployment. This allowed the team to manage migration activity more safely, with clearer validation and better control over release steps.
Together, these components created a migration framework that could support large-scale content movement while establishing a stronger foundation for future digital publishing services.
The Outcome
The migration helped the client consolidate a major publishing portfolio onto a modern AWS-powered platform.
By moving away from fragmented legacy systems, the organisation gained a more consistent publishing environment across brands and regions. Editorial teams benefited from more aligned workflows, while platform teams were able to reduce the complexity of maintaining multiple CMS and hosting environments.
The new infrastructure also improved the organisation’s ability to handle high-traffic periods with greater confidence. Instead of relying on disconnected legacy systems, the client now had a scalable cloud platform designed to support large digital audiences and future growth.
Beyond the immediate migration, the work created a stronger foundation for future product development. With the publishing estate unified on AWS, the client was better positioned to explore new capabilities such as personalisation, AI-assisted editorial workflows, improved content operations, and more advanced digital experiences.
Why It Matters
Large-scale publishers need platforms that can support speed, reliability, content complexity, and audience growth at the same time.
This project shows Vesper’s ability to support complex platform migrations, cloud architecture, data transformation, and enterprise-scale digital delivery. It also demonstrates how careful engineering can reduce operational complexity while creating the foundation for long-term innovation.
