Amazon.com said this week that it's adding push notifications to its web services for developers, reflecting the significant growth in the mobile application market and related services. The fully managed service is cloud-based as well as cross-platform, meaning developers can tap it to send notifications to iOS, Android and Kindle Fire devices. While push notifications is a growing area, it faces challenges including other mobile messaging tools such as SMS and how to avoid annoying users with too many messages.
