80ms response SLO

Alex Sims, Solutions Architect & Sr. Software Engineer at James and James Fulfilment, talks about their journey to 80ms response SLO with PHP & React.

Alex shares how they optimised API performance, specifically highlighting improvements made by altering interactions with Amazon S3 and Redis. Key points include the transition from synchronous to asynchronous S3 processes, the impact of Amazon's SLO on write speed, and the significant runtime reduction achieved through JIT compilation in PHP 8.

We conclude with insights into decision-making in technology architecture, emphasising the balance between choosing cutting-edge technology and the existing skill set of the team.
