Advantage and Disadvantage of Edge Computing

Cloud computing is a huge, highly scalable deployment of compute and storage resources at one of several distributed global locations (regions). Cloud providers also incorporate an assortment of pre-packaged services for IoT operations, making the cloud a preferred centralized platform for IoT deployments. In practice, cloud computing is an alternative — or sometimes a complement — to traditional data centers.


Still other examples are often aligned with utilities, such as water treatment or electricity generation, to ensure that equipment is functioning properly and to maintain the quality of output. If you’re already using a hybrid cloud architecture, then you’re familiar with the benefits of partitioning data between public and private clouds. There are different configurations, and all work well, depending on your business goals and usage.

Bonus tip: The edge computing pizza place analogy

As all networks have a limited bandwidth, the volume of data that can be transferred and the number of devices that can process this is limited as well. By deploying the data servers at the points where data is generated, edge computing allows many devices to operate over a much smaller and more efficient bandwidth. Data’s journey across national and regional boundaries can pose additional problems for data security, privacy and other legal issues. Edge computing can be used to keep data close to its source and within the bounds of prevailing data sovereignty laws, such as the European Union’s GDPR, which defines how data should be stored, processed and exposed. This can allow raw data to be processed locally, obscuring or securing any sensitive data before sending anything to the cloud or primary data center, which can be in other jurisdictions.

  • Edge computing speeds up this process by enabling cameras to perform initial video analytics and recognize events of interest.
  • The device-deployed code responds in real-time by shutting down the IoT machine in case of a damaging failure condition, while the rest of the application runs in Azure.
  • Running AI on a user’s device instead of all in the cloud seems to be a huge focus for Apple and Google right now.
  • A delay in the machine’s decision-making process due to latency would result in losses for the organization.
  • The technologies that are driving edge computing include the Internet of Things (IoT), software-defined networking (SDN), fifth generation wireless (5G) networking and blockchain.
  • The term cloud computing encompasses the delivery of hosted cloud services over the internet.

Your trip can’t survive that kind of latency, and even if it could, the cellular network is too inconsistent to rely on it for this kind of work. Google also is getting smarter at combining local AI features for the purpose of privacy and bandwidth savings. For instance, Google Clips keeps all your data local by default and does its magical AI inference locally. It doesn’t work very well at its stated purpose of capturing cool moments from your life. An intelligent device has its own computing capability so it can process data as close to its source as possible.

Industry solutions and applications can exist in multiple nodes as specific workloads are more suitable to either the device or local edge. Some other workloads can also dynamically move between nodes under certain circumstances (either manually or automatically). Edge computing also helps keep workloads up to date, ensure data privacy, and adhere to data protection laws such as HIPAA, GDPR, and PCI.


IoT-based power grid system enables communication of electricity and data to monitor and control the power grid,[32] which makes energy management more efficient. Passionate about driving product growth, Shivam has managed key AI and IOT based products across different business functions. He has 6+ years of product experience with a Masters in Marketing and Business Analytics. The ultimate result is a latency measured in microseconds rather than milliseconds. As a result, the overall service’s speed, quality, and responsiveness have improved. Edge computing offers a powerful strategy to help alleviate future network congestion driven by new technologies.

Hybrid Cloud and the Edge

Instead of one video camera transmitting live footage, multiply that by hundreds or thousands of devices. Not only will quality suffer due to latency, but the bandwidth costs can be astronomical. A car equipped with edge devices can gather data from various sensors and have real-time responses to situations on the road. Unless a company partners with a local edge partner, setting up the infrastructure is costly and complex. Maintenance costs are also typically high as the team must keep numerous devices at different locations in good health. Cloud gaming companies are looking to deploy their servers as close to the gamers as possible.


Real-time responses to manufacturing processes are vital to reducing product defects and improving productivity within a factory. Analytic algorithms can monitor how each piece of equipment runs and adjust the operating parameters to improve efficiency. Due to the nearness of the analytical resources to the end users, sophisticated analytical tools and Artificial Intelligence tools can run on the edge of the system. This placement at the edge helps to increase operational efficiency and is responsible for many advantages to the system. Healthcare startup Innocens BV identifies infants at risk of developing sepsis with predictive edge computing.

Everything from virtual reality headsets to gaming devices to IoT devices on manufacturing floors interact with edge computing topologies set up by telecoms. Some of the most simple forms of edge computing involve basic events and straightforward processes. For example, a device that can monitor someone’s pulse and blood pressure can be positioned on their body and then send information to an edge-based server. Only certain information is then sent to the cloud, while most of it is handled within the edge network. IoT is a system of linked computing machines, devices or objects that can transfer data across networks without human interaction. IoT devices are anything — or anyone — that can have an IP address and transfer data over networks.

In edge computing, there is a local storage and local servers can perform essential edge analytics in the event of a network outage. Latency refers to the time required to transfer data between two points on a network. Large physical distances between these two points coupled with network congestion can cause delays.

What is multi-access edge computing?

The advent of 5G promises data speeds of over 20 Gbps and delay-free connections of over a million devices per square mile. This emerging technology pushes edge computing to a new level, enabling even lower latency, edge-computing-definition higher speeds, and enhanced efficiency. Virtualization is a vital element of a large-scale edge computing setup. This technology makes it easier to deploy and run numerous applications on edge servers.


In addition to the possibility of simplifying cloud security approaches,
edge computing can also result in significant cost reductions due to lower
bandwidth. Because so much data is now processed and stored in localized servers and devices, there is no need for most data to go to data centers. As a result, edge computing requires less bandwidth at the data center level. Latency reduction is one of the hallmarks of edge computing, and it is made possible because of the proximity of the edge devices and where their data is stored and processed.

What is edge computing and why does it matter?

According to a study by Gartner, 75 percent of enterprise generated data will be created outside of centralized data centers by 2025. This amount of data puts an incredible strain on the internet, which in turn causes congestion and disruption. Edge computing is a distributed IT architecture which moves computing resources from clouds and data centers as close as possible to the originating source. The main goal of edge computing is to reduce latency requirements while processing data and saving network costs. But this virtual flood of data is also changing the way businesses handle computing. The traditional computing paradigm built on a centralized data center and everyday internet isn’t well suited to moving endlessly growing rivers of real-world data.
