• Security Concerns: Data security becomes a shared responsibility between the organization and the cloud provider. Organizations need to carefully evaluate the cloud provider’s security practices and also compliance certifications to ensure data privacy and regulatory adherence.
• Potential Network Latency: Depending on the location of the cloud resources and also the volume of data being transferred, network latency may become a concern, impacting performance in latency-sensitive applications.

3. Edge Deployment:

Edge computing refers to processing data closer to its source, often on devices or embedded systems at the network’s edge, rather than sending it to a central location. This approach offers:

Reduced Latency:

• Real-time decision-making: Edge computing shines in applications requiring immediate action based on data analysis. For example, in self-driving cars, real-time object detection and classification at the edge enable critical decisions like obstacle avoidance or lane changes with minimal delay.
• Improved responsiveness: In industrial automation, edge processing enables faster analysis of sensor data, allowing for real-time adjustments to manufacturing processes or preventive maintenance based on early detection of anomalies.
• Enhanced user experience: Edge processing can significantly improve user experience in applications like augmented reality (AR) or virtual reality (VR) by minimizing the latency between user actions and system responses.

Improved Bandwidth Efficiency Data Infrastructure For ML

• Reduced network congestion: By processing data locally, edge computing reduces the amount of data transmitted through the network, leading to less congestion and improved overall network performance. This is crucial in scenarios with limited bandwidth, such as remote locations or applications with high data volume, like video surveillance.
• Lower network costs: Reduced data transmission translates to potentially lower network costs, especially for organizations with geographically dispersed operations or those utilizing bandwidth-intensive applications.
• Improved scalability: Edge deployments can be easily scaled by adding more edge devices to the network, supporting increased data processing demands without overloading the central infrastructure.
