Generative AI Summarisation for a Global Technology Publisher

Overview

A global technology publication wanted to explore how Generative AI could improve reader engagement without disrupting its existing editorial workflow.

The publisher’s editorial platform was powered by WordPress, and the team wanted a practical way to generate concise article summaries for long-form content. The solution needed to support editorial control, integrate with the existing CMS, and allow the organisation to experiment safely with different large language models.

Vesper designed and delivered a custom AI summarisation workflow that connected WordPress with Amazon Bedrock through a secure serverless architecture.

The Challenge

The client wanted to introduce AI into the publishing process carefully and responsibly.

Key requirements included:

• Generating concise summaries for long-form articles

• Keeping editors in control of when summaries were created and published

• Avoiding disruption to the existing WordPress editorial workflow

• Allowing experimentation with different foundation models

• Building a secure bridge between WordPress and AWS AI services

• Creating a scalable solution without always-on infrastructure

The project needed to prove that AI could support editorial teams without replacing editorial judgement or creating unnecessary complexity.

The Solution

Vesper built a custom WordPress plugin that allowed editors to generate summaries directly from the CMS.

Editors could select an article, trigger the summary workflow, review the result, and decide how it should be displayed. This kept the editorial team in control while making AI summarisation available inside the tools they already used.

The plugin connected to Amazon Bedrock through Amazon API Gateway and AWS Lambda. This allowed the publisher to test different foundation models without rebuilding the system or locking the workflow to a single AI provider.

The architecture was designed to be secure, flexible, and scalable, with AWS handling model access, request processing, and monitoring.

Technical Delivery

The solution included:

• A custom WordPress plugin for editorial use

• Amazon API Gateway for secure API access

• AWS Lambda for serverless request handling

• Amazon Bedrock for access to foundation models

• Amazon CloudWatch for monitoring and logging

• IAM roles and policies for least-privilege access

The workflow was designed to support model flexibility, allowing the editorial team to test tone, length, and style across different AI models.

The Outcome

The project gave the publisher a practical and controlled way to introduce Generative AI into its editorial workflow without disrupting the CMS or reducing editorial oversight.

Editors were able to generate article summaries on demand from within WordPress, review the output, and decide how the summary should be used before publication. This meant the AI workflow supported editorial teams rather than replacing their judgement.

The solution also gave the publisher flexibility to experiment with different foundation models and compare tone, length, and quality without rebuilding the integration. Because the architecture was serverless and connected through AWS, the system could scale with publishing demand while avoiding unnecessary always-on infrastructure.

Beyond summarisation, the project created a strong foundation for future AI use cases, including translation, Q&A, content personalisation, and other editorial tools.

Why It Matters

Many publishers want to explore AI but cannot afford to compromise editorial control, trust, or workflow stability.

This project shows Vesper’s ability to implement AI in a practical, production-ready way that supports teams rather than disrupting them.

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.

Modernising a UK Energy Supplier’s Core Operations Platform

Overview

A UK-based energy supplier needed to modernise its internal operations and replace fragmented manual processes with a secure, scalable digital platform.

The organisation managed a complex set of workflows across contracts, customer accounts, broker relationships, quotes, meters, billing, and internal administration. Much of this work relied on disconnected tools and manual coordination, creating operational inefficiency and limiting the company’s ability to scale.

Vesper designed and delivered the foundation for a modern cloud-based energy portal, giving the client a central platform for staff, brokers, and customers.

The Challenge

The client needed a platform that could support day-to-day operations while creating a long-term foundation for future growth.

Key challenges included:

The platform was designed using AWS technologies, with clear separation between web, application, and database layers. Infrastructure was provisioned using Infrastructure as Code, allowing environments to be created consistently and managed with greater control.

Vesper established separate environments for development, testing, staging, and production, supported by automated CI/CD pipelines. This gave the team a safer and more predictable release process.

The initial product release focused on the staff portal and core operational modules, including quotes, contracts, billing, and meters. Role-based access controls were introduced to support different user groups and protect sensitive operational data.

Technical Delivery

The platform used a modern AWS-based architecture, including:

• Amazon ECS Fargate for managed containerised application hosting

• Amazon Aurora Serverless for scalable relational data storage

• AWS Lambda and EventBridge for background tasks and scheduled operations

• Amazon CloudFront and S3 for secure content delivery and file storage

• AWS KMS for encryption at rest

• AWS Certificate Manager for secure communications

• Amazon CloudWatch and CloudTrail for logging, monitoring, and auditability

• Terraform for Infrastructure as Code

• GitHub Actions for automated testing and deployment

The delivery model combined product management, engineering, QA, and design, with close collaboration between Vesper and the client’s business team.

The Outcome

The project gave the client a secure and scalable operational platform that could support both current workflows and future expansion.

Key outcomes included:

• Deployment of the core platform infrastructure

• Launch of the initial staff portal

• Centralisation of contracts, quotes, billing, and meter workflows

• Reduced reliance on manual processes

• Improved operational visibility and data accuracy

• A stronger technical foundation for future portal features

• More efficient collaboration between technical and business teams

The platform created a long-term foundation for the client to continue modernising operations and expanding digital services across staff, broker, and customer journeys.

Why It Matters
