GraphQL @ Scale

Section: Full talk Technical level: Intermediate Status: Submitted


Modern web servers need to cater to multiple clients on web, mobile and desktop. The views across the clients vary a lot, so same server API response across all clients is not optimal. GraphQL offers a powerful technology for building web API’s which enables clients to query data which they want and how they want without compromising on the performance.

As a part of this talk I am going to talk about our GraphQL journey while building Microsoft Teams. We will focus on how we built a scalable, multi geo deployed GraphQL Server backed by Azure Cosmos DB powering some key features in Microsoft Teams.


  • What is GraphQL?
  • Why GraphQL over REST?
  • Best practices for designing a GraphQL schema
  • GraphQL Server Architecture in Teams
  • Various GraphQL patterns we put in
    • Error handling
    • Telemetry & Monitoring
    • Throttling patterns.
  • Best Practices
  • Deployments

Speaker bio

I am Jatin Thapar Software Engineer from Microsoft India Development Centre, Bengaluru and working on building a Data Layer for ‘Teams’ services with a GraphQL endpoint. It has been close to 5 years working on backend developer, shipping enterprise software products. In Microsoft had a privilege of working on a new and fast growing product, Microsoft Teams and learning each day on being customer focussed and compliance first.

Working with databases has always been exciting for me, right from my graduation days!!

    The slides are not acessible, Jatin. Change permission settings and open access. We also need to see a preview video, by 30 April, to complete evaluation of your proposal.

      Thanks Zainab, I have changed the link for the ppt, you should have permission now. Will post a preview video in a day or two.

      • Zainab Bawa (@zainabbawa) a year ago

        Thanks Jatin. The slides are mainly headline bullet points. This makes it difficult for us to evaluate the content. I expect that the preview video will be more detailed.

          Also, tell us why participants at Rootconf should be interested in listening to this talk. What are the takeaways for them?

            Hi Zainab, thanks a lot for the feedback. I have uploaded the video with what I will be covering in my talk and key takeaways for the audience. Let me know if something else is needed.
