Building Android OTA Infrastructure vs. Buying It: What Shipping Firmware Safely Actually Takes

Android Original Equipment Manufacturers (OEMs) face the challenge of delivering firmware updates efficiently and safely to their devices, which involves creating a comprehensive Over-The-Air (OTA) update system. This system requires six key infrastructure components: servers and backend, CDN distribution, cryptographic signing, staged rollout and rollback logic, per-device tracking, and a dedicated team for operations and maintenance. Building such an infrastructure in-house can divert engineering resources from core product development and may not offer a competitive advantage, as it is considered a standard expectation in the industry. Esper Airwave provides an alternative by offering a managed OTA solution that handles most of these components, allowing OEMs to focus on product development while ensuring secure and efficient firmware updates. The decision to build or buy OTA infrastructure depends on whether the OTA system is a core product offering or simply a necessary infrastructure that protects revenue without generating it.
