Introduction
Another way to reduce latency is through edge computing. This type of computing takes place at the edge of a network, rather than at its center. With this model you have your services running on devices that are closer to users and their devices, which means there’s less distance for communication between them. The idea behind Edge Computing is that it would allow for faster responses from applications because they wouldn’t have to wait for data from a centralized location before responding. It also reduces latency because fewer devices must be traversed as data moves across the network.
There are several parts of the cloud world that are changing to bring new levels of performance and reliability forward.
The concept of Edge Computing is not new. In fact, it’s been around for several years now and has been gaining popularity as the next step in data center evolution. You may have heard about it before or even used some form of Edge Computing yourself–but what exactly is it?
In short: It’s the future of cloud computing!
The current model for cloud computing has applications and services running on a centralized data center, with clients and devices communicating with it over a network.
The current model for cloud computing has applications and services running on a centralized data center, with clients and devices communicating with it over a network. This model has been successful for many applications and services but it’s not the best solution for all of them. The limitations of this approach include:
- Latency–the time it takes to send information from one point to another over the network (this includes both physical distance as well as any delays caused by packet loss or congestion).
- Reliability–if there are too many users accessing an application at once, then performance will suffer because resources are limited in those environments.
Edge computing is changing this landscape by allowing businesses to deploy their own processing power closer to where their data is generated so they can offload some of these tasks onto edge devices instead of relying solely on centralized cloud resources which may be further away than necessary or susceptible to outages due to heavy traffic loads being placed upon them
Latency is the time it takes for a packet to travel from its point of origin, through the network and back again.
Latency is the time it takes for a packet to travel from its point of origin, through the network and back again. It’s often expressed in milliseconds (ms).
Latency is defined as “the time interval between when a signal leaves one node until it arrives at another node” [1]. The term can be applied to any kind of system where information must pass through multiple stages before reaching its intended destination, such as networked computer systems or telephone networks with long distance connections between cities or countries.
Latency comes from many sources including the distance between devices, the number of devices along the path and the speed of those devices.
- Distance is a major factor for latency. The more distance between your devices, the longer it takes for information to travel from one device to another.
- The number of devices along the path will also cause latency. If there are many routers and switches along your network, then you’re going to have higher latency because each time data passes through one of them, there’s an extra delay introduced into your system by those extra steps in routing traffic across networks.
- Lastly, speed matters! Slower speeds mean longer times between sending and receiving packets which results in higher latencies overall (and thus lower performance).
The problem with latency is that it limits how fast an application can respond to user actions or external events like sensor input or device alarms.
Latency is a problem for applications that need to respond quickly. For example, if you’re playing a game and you press the button on your controller to make your character jump, but it takes several seconds for that input to reach the server and be processed before responding with an animation of your character jumping, then your experience will be ruined.
The same goes for industrial IoT systems: if it takes too long for data from sensors or alarms to get back to the cloud or control center where it can be analyzed by humans (or even other machines), then those systems are effectively useless at helping people make decisions in real time.
Edge computing reduces latency by bringing computation closer to where data originates so that responses aren’t delayed–and this has huge implications for all types of businesses looking at edge computing solutions today!
High-speed trading depends on low latency systems in order to execute trades at speed before other market participants.
High-speed trading is a way to make money by buying and selling assets quickly. It’s important for high-speed traders to execute trades at speed before other market participants. Low latency systems are necessary for this, but they’re also used in many other applications where responsiveness is critical:
- Autonomous vehicles require low-latency data from sensors in order to drive safely
- Virtual reality applications need real-time information about head orientation so that users don’t feel sick while wearing headsets
- The Internet of Things (IoT) relies on edge computing because it has no central hub or server; instead, each device acts autonomously
Edge Computing is one possible solution to reducing latency.
Edge Computing is a model that moves the computing power closer to the data. In this way, it can reduce latency by moving the processing closer to where your data lives. It has many applications in industries such as AI/ML, AR/VR and HMI (Human Machine Interface).
Conclusion
The future of computing is going to be very different from what we’re used to today. The cloud will still play an important role, but it won’t be the only place where applications run. Edge Computing is a technology that allows us to run software closer–and in some cases even within–devices themselves. This means faster response times and lower bandwidth usage, which makes it especially useful for IoT applications where latency matters most!
