Cloud providers offer multiple ways to use server applications with reliable methods of maintaining horizontal scalability, disaster recovery, and high availability.
For example, you could efficiently run a major banking application in the Kubernetes cloud-based cluster with hundreds of nodes and maintain efficiency.
However, IoT applications are different. As they are distributed by nature, classic cloud architectures are no longer relevant.
The IoT cloud is a distributed cloud (Image 1) with a specialized underlying infrastructure, services, virtual private cloud (VPC), and network configuration for real-time operations and IoT data processing.
For example, your IoT devices may need to communicate with each other using the MQTT protocol with an advanced level of security and encryption.
Or, you may want to group your devices in 5G/GSM wireless zones across regions.
Cloud providers give you instruments to develop such an infrastructure by using essential services, production-ready solutions, and accelerators, which we will cover later.
The IoT cloud must provide an easy way to maintain an increasing number of connected devices across different locations with a simple firmware update process.
This infrastructure should be flexible, cost-effective, and secure.
