What is Edge Computing?

Edge computing is a distributed computing model in which computing takes place near the physical location where data is being collected and analyzed, rather than on a centralized server or in the cloud. This new infrastructure involves sensors to collect data and edge servers to securely process data in real-time on site, while also connecting other devices, like laptops and smartphones, to the network.

By 2025, 175 zettabytes (or 175 trillion gigabytes) of data will be generated around the globe. Edge devices will create more than 90 zettabytes of that data.

Why is Edge Computing Important?

Edge computing is important because it creates new and improved ways for industrial and enterprise-level businesses to maximize operational efficiency, improve performance and safety, automate all core business processes, and ensure “always on” availability. It is a leading method to achieve the digital transformation of how you do business.

Powers the next industrial revolution, transforming manufacturing and services.

Optimizes data capture and analysis at the edge to create actionable business intelligence.

Creates a flexible, scalable, secure, and more automated technology, systems, and core business process environment.

Promotes an agile business ecosystem that is more efficient, performs faster, saves costs, and is easier to manage and maintain.

Increasing computing power at the edge is the foundation needed to establish autonomous systems, enabling companies to increase efficiency and productivity while enabling personnel to focus on higher value activities within the operation.

What Are the Benefits and Challenges of Edge Computing?

One of the top benefits of implementing edge computing is the ability to collect and analyze data where it is collected, catching and correcting problems that might not be identified as quickly if the data were to be sent to a central server or cloud for processing and analysis. Keeping data on site also reduces the security risk associated with porting data, which can be important in financial organizations, for example. It also reduces bandwidth costs by processing some data on site, rather than sending all data to a cloud or central server.

Successful edge computing requires a thoughtful architecture and implementation , which can be a challenge without the right expertise. Having multitudes of sites collecting and analyzing data can mean more sites that need to be configured and monitored, adding complexity. Having too few can mean critical data is missed. Decentralized locations can also mean fewer technical personnel on site, meaning non-technical operations staff may be called in to troubleshoot. These challenges can be addressed by working with knowledgeable system integrators and using the right edge technology.

How Secure Is the Edge?

Because edge computing is distributed, the security risk is different than a centralized environment. The security controls found in private data centers or public clouds, like firewalls or antivirus tools, don’t automatically transfer. Experts recommend a few simple steps, including hardening each host, real-time network monitoring, encrypting data, and adding physical security measures.

91% of today’s data is created and processed in centralized data centers. By 2022 about 75% of all data will need analysis and action at the edge.

The Cloud and the Edge

Does the Edge Replace the Cloud?

Edge computing works hand in hand with the cloud to provide a flexible solution based on the data collection and analysis needs of each organization. For real-time collection and analysis, the edge is ideal for certain workloads. At the same time, the cloud can provide a centralized location for large scale analytics.  Together they provide real-time and longer term insights into performance and power initiatives like machine learning and asset performance management.

Hybrid Cloud and the Edge

If you’re already using a hybrid cloud architecture, then you’re familiar with the benefits of partitioning data between public and private clouds. Edge computing can be a great addition to this existing network. There are different configurations, and all work well, depending on your business goals and usage. For example, the edge can take the place of the private cloud, taking the primary computing role, or you can pair the edge with an existing hybrid cloud with both public and private clouds.
