Event Sponsor

ATG are sponsoring GraphQL: The Gateway to Effective Microservices

Our March outing, hosted by ATG (Ambassador Theatre Group), will revolve around the question of how GraphQL can help enable effective microservices. Whilst teams have been breaking down monoliths for many years, has the rise of GraphQL changed the game?

Please note: Sadly, we've made the decision to postpone all Growable events as a response to COVID-19 (coronavirus). We will be announcing a new date and location for this event in the coming months; sign up below to receive updates directly.

Our first speaker for the evening is Marc Roberts, Engineering Manager for ATG. Marc will be sharing some lessons and personal insights from his experiences migrating existing monoliths to microservices, with a specific focus on how GraphQL helped his team achieve their goals quickly and successfully from both a business and developer experience (DX) point of view.

ATG is the world’s number one live-theatre organisation, employing over 3,500 people across six international offices and operating over 50 venues across Britain, the US and Germany. They run one of the UK’s largest ticketing sites and have plans in place to rebuild this into a multi-device eCommerce platform that will be better able to cope with the phenomenal traffic volumes they experience.

Over the last year they’ve built out the engineering team to 12, including Engineering Manager, Marc Roberts. Their new microservices architecture is built with React with a Node.js and Apollo GraphQL back-end, whilst utilising AWS Lambda, Lambda@Edge, DynamoDb, Aurora with GitHub Actions, illustrating their absolute focus on leading-edge technologies., illustrating their absolute focus on leading-edge technologies. With aims to create data and API layers to embrace the power of Cloud architecture within AWS, they are well positioned to impact the technology world.

We will be announcing the second speaker for this event soon! Please register to get updates straight to your inbox.
