- Edge PaaS facilitates the processing of data from sensors on autonomous vehicles at the edge, enabling quick decision-making.
3. Smart Cities:
- Edge PaaS can be employed in smart city initiatives for real-time monitoring, analysis, and decision-making in areas like traffic management and public safety.
4. Industrial IoT (IIoT):
- In industrial settings, Edge PaaS supports the deployment of applications for monitoring and controlling machinery, optimizing production processes.
5. Augmented Reality (AR) and Virtual Reality (VR):
- Edge PaaS reduces latency in AR and VR applications by processing data locally, delivering a more immersive and responsive user experience.
Challenges in Edge PaaS
1. Resource Constraints:
- Edge devices often have limited resources compared to cloud servers, posing challenges in deploying resource-intensive applications.
2. Diversity of Edge Environments:
- Edge PaaS must accommodate diverse edge environments, ranging from IoT devices with constrained resources to more powerful edge servers.
