Linden Lab has spent over a decade optimizing the production operations for Second Life, an online 3D virtual world created by its users. With our new social VR platform, Sansar, we wanted to take our vision of virtual experiences to a whole new level of innovation in which AWS played a vital role. We’ll dive into Sansar’s AWS tech stack, an infrastructure built not only for technical robustness but also extreme scalability. We will discuss what the different use cases were between EC2 and Containers and how Lambda worked as a positive enabler for customization. Lastly, we’ll cover IAM, Security Groups and VPC, which we refer collectively as the “Great Wall of Preventing Unfortunate Design Decisions.”.
