How do you design secure and scalable edge applications?

1 What is edge computing?

Edge computing is a distributed architecture that decentralizes the processing and storage of data from the cloud or the core network to the edge of the network, where the data is generated or consumed by devices, sensors, or users. Edge computing can improve the performance, reliability, and security of applications that require low latency, high bandwidth, or real-time processing, such as IoT, AR/VR, gaming, or streaming. Edge computing can also enable new use cases and business models that leverage the data and insights from the edge devices.

2 Why is edge computing challenging?

Edge computing presents a number of challenges for software developers who need to design and deploy applications that run on heterogeneous, dynamic, and resource-constrained edge devices and platforms. Security is a major concern, as edge devices and networks are more exposed to cyberattacks, physical tampering, and data breaches than centralized systems. Developers must ensure that data and code are encrypted, authenticated, and protected from unauthorized access or modification. Additionally, applications must be able to handle variable and unpredictable workloads, traffic, and data volumes, as well as scale up and down, balance the load, and recover from faults. Compatibility is also an issue, as edge devices and platforms have different capabilities, standards, and protocols, which can affect the interoperability and performance of applications. Finally, applications must be able to be deployed, configured, and maintained efficiently and securely, despite network latency, bandwidth, and availability.
