How does edge computing help vs alternatives?
By processing data closer to where it’s generated, edge computing powers these systems to be faster, smarter and more secure.
Modern AV installations demand performance, security, and scalability to keep up with thousands of complex interactions with people every day.
Here’s how edge computing compares vs alternatives to powering modern AV installations.
1. Latency
- Cloud Computing: Relies on centralized servers, often located far from the point of data generation. This geographical separation introduces latency, which can result in frustrating delays in time-sensitive applications like live video streams or interactive displays.
- Traditional Centralized Data Processing: Similar to cloud computing, this approach processes all data at a central location. The distance between end devices and the central server adds significant delay, especially for AV systems handling large volumes of data.
- Edge Computing: Processes data locally, at or near the source (e.g., a retail store, concert venue, or airport). This minimizes latency, ensuring real-time responsiveness in applications like live event broadcasting or interactive retail signage.
Example: Consider a video conferencing system. Centralized processing might cause awkward lags in communication, while edge computing ensures smooth, real-time interactions, especially for high-stakes corporate meetings.
2. Data Processing Speed
- Cloud Computing: Cloud systems often have high computational power but can struggle with speed when vast amounts of data travel back and forth over the internet.
- Traditional Centralized Data Processing: Capable of handling powerful computing tasks but quickly bogged down by bandwidth constraints when dealing with massive AV datasets, such as high-definition video streams.
- Edge Computing: Processes high volumes of data locally, avoiding the bottlenecks of upload/download speeds through a central server. This results in quicker, more efficient data handling.
Example: Digital signage in a shopping mall that adapts content based on real-time foot traffic achieves faster results with edge computing than waiting for cloud-based interactions.
3. Security
- Cloud Computing: Centralized clouds transmit sensitive data over public or private networks, increasing exposure to potential hacking during transit.
- Traditional Centralized Data Processing: Similar to cloud computing, data travels long distances, leaving more opportunities for interception.
- Edge Computing: By processing data locally, sensitive information doesn’t have to travel far, reducing the risk of interception. For instance, in smart classrooms, student audio and video data remain protected by staying within the physical location.
Example: Smart hospitals using edge computing secure patient records by avoiding the transmission of data to distant servers, unlike cloud-based systems that are more vulnerable to breaches.
4. Bandwidth Usage
- Cloud Computing: Transferring large AV files and streams to and from the cloud requires significant bandwidth, leading to higher costs and network congestion.
- Traditional Centralized Data Processing: Centralized systems often demand even more bandwidth, as every device relies on communicating with one distant server.
- Edge Computing: Reduces bandwidth reliance by processing data locally and only sending essential information to the cloud or central system when necessary.
Example: Stadiums broadcasting events in real-time would struggle with bandwidth surges if streaming every video feed to the cloud. Edge computing processes streams locally, reserving the network for critical uploads.
5. Scalability
- Cloud Computing: Easy to scale up or down based on demand, as resources in cloud data centers are virtually limitless.
- Traditional Centralized Data Processing: Scalability is limited, as adding more devices puts significant strain on a single central server.
- Edge Computing: Scalability across many devices requires careful planning to deploy edge nodes effectively. However, this is improving with advancements in IoT and distributed systems.
Example: A retail chain expanding its network of connected AV displays might benefit from the scalability of the cloud but could use edge computing for individual stores to optimize processing locally.
Why Choose Edge Computing?
