Introduction Edge AI
Processing data near the edge of the network, where the data is generated, instead of a centralized data-processing warehouse. Edge computing enables mobile computing and IoT technologies. It makes data and devices more affordable and connected without increasing responsiveness and reducing latency. Let’s take a deep dive into edge computing and understand how the technology works with Akira.ai's solution for business users.
Edge AI has the potential to revolutionize how AI technology is developed and used worldwide. Click to explore our, Edge AI Architecture and its Applications
Why do we need Edge AI?
Emerging technologies like deep learning and neural networks, which have revolutionary potential depending on cloud computing, hampers its runtimes increasing massive power requirements.
Forrester Research, an International Informational Technology Firm, reports that “ Latency is becoming an issue as firms try to push more data to software that runs in the cloud or the data center.” As the amount of data increases, it becomes more uneconomical to do all processing centrally.
Edge Computing acts as efficient technology that brings intelligence closer to the place where intelligence is needed and, in return, unleashes the collective power of intelligent devices. As the number of firms grows and increases, central software platforms handling the inflow of data are being pushed to the edge. The main motivations for choosing Edge Computing are:
- Real-time data processing without latency or delay in the transfer of data.
- Eliminates lag time or allows smart applications to respond to data instant.
- A large amount of data is processed near sources resulting in reduced internet bandwidth.
- Eliminates costs ensuring applications to be used in remote locations.
- Processing data without putting it in the cloud adds security for sensitive data.
