The Cloud Edge Computing Vendors are offering specialized gateways, firewalls, and other solutions to manage and process a large amount of data that is generated by edge devices. Data can be captured, processed, and analyzed in near real-time with edge computing. It can also filter out data that isn’t needed, sending only important data to a data center.
Handling data processing at the edge improves the performance of applications like augmented reality (AR), virtual reality (VR), machine learning (ML), and artificial intelligence (AI). Data computing can also be used in remote location which prevent data from leaving its source. Additionally, utilizing the local area network (LAN) for data processing and storage results in fewer data transfers to the cloud, lowering operational expenses. Even though it is thought that streaming data to the cloud or a data center is more efficient, keeping data at the edge still requires security.
To prevent theft or a cyberattack, data encryption policies must be in place for all data being streamed and stored. The viability of edge data processing is dependent on maintaining a robust edge security posture. Although cloud edge computing has great potential to boost processing capacity, it presents major management challenges for IT teams. IT teams must manage an increasing variety of enterprise cloud platforms, each with its own set of tools and processes, as cloud edge computing is added to public and private cloud resources. The end effect is a sort of managerial chaos that can only lead to more expenses, more complexity, and restrictions on innovation, agility, and speed.
Cloud computing is the delivery of computing services, such as applications, databases, and storage, from a remote location, usually provided as an on-demand service. According to Aidan Fitzpatrick, reincubate CEO, the concept started as a way for businesses to rent out spare capacity from their pre-existing server infrastructure to third parties via the internet.
As the name implies, edge computing involves putting computing resources on the outer edge of a network. The concept emerged from the need to reduce latency in communications, particularly with videos, gaming, and high-frequency trading (e.g., stocks, bonds, currencies), where milliseconds in delays can greatly degrade the user experience. Latency is proportional to geographic distance. The latency will increase if this flow needs to travel a large distance (e.g., between countries or across continents).
To reduce latency, content delivery network (CDN) providers, such as Akamai, Cloudflare, and others (including some that also offer cloud services), established global server networks, re-routing the end user’s traffic so instead of going directly to the server, they were instead directed to the nearest copy of that data on the CDN’s own servers.
Rather than merely caching static data, CDN providers enabled customers to run some of the applications that would otherwise be run on a server or on a cloud computing platform directly on the CDN servers, providing the benefit of low latency without the drawback of storing only static data, Fitzgerald said.
A key benefit of edge computing is that users get a better experience in terms of reliability, speed, and potentially better privacy, helping companies comply with data sovereignty regulations by keeping data on location while still being able to provide all of the features expected of modern cloud-based software. Edge computing mitigates issues around resilience (i.e., you can still act even when there is no network connectivity), latency with processing happening in real-time, and network congestion because you only send the most relevant insights to the cloud. Of course, there are additional capabilities required for effective edge computing as use cases and locations can vary. For example, smaller resource constrained devices have different needs than a traditional server.
