Space: The New Frontier for Network Design

Satellite constellations are significantly enhancing global connectivity, extending internet access worldwide. The current focus is shifting towards incorporating compute capabilities in orbit, which will fundamentally redefine how digital services are architected and delivered.

Space infrastructure presents distinct challenges, including launch capacity, radiation, and power limitations. Consequently, orbital compute resources are expected to be more specialized than large-scale terrestrial data centers. Instead of replicating existing models, space will foster novel distributed compute and storage nodes that work in tandem with Earth-based systems.

This paradigm shift emphasizes extending the internet's distributed architecture rather than simply relocating data centers. Organizations may distribute functions across diverse environments like terrestrial clouds, edge platforms, and space-based systems, optimizing for architectural efficiency and user experience.

Satellite constellations operate dynamically, necessitating constant adjustments in network paths and routing topologies. These systems differ from terrestrial networks in latency, with low-Earth orbit constellations offering round-trip times of 20-40ms, and in bandwidth asymmetry, often favoring downloads over uploads.

As a result, not all computational tasks are suited for space. Effective architectures will carefully balance workload placement based on latency sensitivity, data volume, and operational constraints. This integrated approach combines terrestrial fiber, subsea cables, wireless networks, cloud, edge, and orbital systems.

The complexity of these interconnected infrastructures remains invisible to end-users, who expect seamless service. However, performance issues can arise anywhere along the extended path, from local networks to satellite ground stations. Understanding these interactions is crucial for building resilient digital services.
