It can come in via more very efficient small devices that can run on different energy sources, whether that’s the sun or extracting energy from the soil through a photosynthesis process. The ability is there today to collect the data. These are just a few examples of how we can dramatically eliminate waste and also improve the productivity of farming. You could apply the data to determine whether what’s needed is water or fertilizer or pesticide, and it can be applied in a much more efficient way. You can use that data to get insights in terms of the conditions of the crops and the needs around irrigation, specifically for a given field or crop. It’s estimated that half of the water is used for irrigation - this was determined via devices placed out in the field. Farms around the world use about 70% of our fresh water, in terms of annual consumption. If you’re banking on commodity systems always performing better than centralized cloud computing systems, that may not always be the case.Martino: Let’s consider agriculture. If performance is a core reason you’re moving to edge computing, you need to think about how it should be engineered and the additional cost you may have to endure to get to your target performance benchmark. Additional expenses to operate and maintain those edge computing devices.The complexity of managing many edge computing devices that exist near the sources of data.Like other architectural decisions, there are many trade-offs to consider when moving to edge computing: Also, the primary benefit of edge computing has been the ability to provide better data and processing performance, and this issue would blow a hole in that benefit. I’m just pointing out some issues that the people designing these systems need to understand before finding out after deployment. Once these problems are discovered, the potential fixes are not economically viable. But remember that you need to multiply those upgrades times 1,000+. Yes, there are ways to solve this problem, such as bigger caches, device tuning, and more powerful edge computing systems. Of course, your performance will depend on the speed of the network and the number of hops. What if you have thousands of edge devices that may only act on processes and produce data as requested at irregular times? Systems calling out to that edge computing device will have to endure 3- to 5-second cold-start delays, which for many users is a dealbreaker, especially compared to consistent sub-second response times from cloud-based systems even with the network latency. If code was not launched or data not gathered recently, those things won’t be in cache and will be slow to launch initially. There may be good reasons not to push so much processing and data storage to “the edge” unless you understand what the performance benefits will be.ĭriving much of these performance problems is the cold start that may occur on the edge device. The shortfalls are being whispered about at Internet of Things and edge computing conferences and are becoming a limitation on edge computing. So, is edge better because it provides better performance due to less network latency? In many instances, that’s not turning out to be the case. Compare this versus a round trip to the back-end cloud server that exists 2,000 miles away. If you have a device that’s 10 feet from where the data is gathered and that's also doing some rudimentary processing, the short network hop will provide almost-instantaneous response time. One of the promises of edge computing-and the main reason for picking edge computing architecture-is the ability to reduce network latency. I’ve even noticed vendors “edge washing” their technology, promoting it to “work at the edge.” If you think about it, all mobile phones, PCs, and even your smart TV could now be considered edge computing devices. ![]() It’s safe to say that there are all types of compute and data storage deployments that qualify as edge computing solutions these days. ![]() This article does a better job of describing the types of edge computing solutions that are out there, saving me from relisting them here. Where there is a factorial of 50 kinds of cloud solutions, there is a factorial of 100 edge solutions or architectural patterns that exist today. Edge computing is one of those confusing terms, much like cloud computing.
