Simply defined, edge computing is a distributed, open IT architecture that features decentralized processing power, enabling mobile computing Internet of Things (IoT) and other low latency technologies. With edge computing, data is processed by the device itself or by a local computer or server, rather than being transmitted to a distant data center. Edge computing enables data-stream acceleration, including real-time data processing without latency. It allows smart applications and devices to respond to data almost instantaneously, as it’s being created, eliminating lag time.

Currently, data management and analysis are performed in the cloud or at a far away data center. However, in an edge computing model, sensors and connected devices transmit data to a nearby edge computing device, housed in a local data center instead of transporting it back to the cloud or a remote data center.

While still a nascent technology, edge computing allows for efficient data processing in that large amounts of data can be processed near the source, reducing Internet bandwidth usage. This both reduces costs and ensures that applications can be used effectively in remote locations. In addition, the ability to process data without ever putting it into a public cloud adds a useful layer of security for sensitive data.

So Many Things, So Much Data

To better comprehend the need for edge computing one must take into account the explosive growth in IoT systems and applications expected in the coming years. According to a report by the International Data Corporation (IDC), by next year, 45 percent of IoT-created data will be stored, processed, analyzed and acted upon close to, or at the edge of the network. Meanwhile, IHS Markit forecasts that the IoT market will grow from more than 15 billion devices three years ago to approximately 30 billion devices by 2020 and more than 75 billion in 2025.

Beyond the most frequently reported consumer use cases such as autonomous vehicles and wearables, the IoT is set to transform such industries as agriculture, construction, energy, manufacturing, healthcare, mining, public safety and utilities. Additionally, considering that many U.S. and European metro areas have launched smart city initiatives, it’s no surprise that IHS Markit predicts that global data transmissions, driven by the growth of IoT connected devices and sensors, are expected to increase from 20 to 25 percent annually to 50 percent per year, on average, over the course of the next 15 years.

With so many, many things producing so much data, it’s important to realize that in many instances these connected devices and sensors will only be effective at multigigabit speeds and sub-millisecond latency. Behind the wheel of an autonomous vehicle driving 65 miles per hour on the local interstate, the one second latency we find acceptable in our favorite app could mean the difference between the car’s sensors detecting and automatically swerving out of the path of an oncoming 18-wheeler, or an unfortunate fender-bender. That’s where edge computing, by placing processing and storage capabilities near the edge of the network, can ensure speed and latency requirements.

In the field of healthcare, Emergency Medical Services is also undergoing a transformation thanks to the advent of edge infrastructure and IoT systems and applications. Today, ambulances are primarily used as transport to a local hospital, but due to the impact of edge computing and IoT, ambulances will soon resemble mobile emergency rooms.

The next generation of EMS practitioners will be able to conduct high-definition, two-way video dialogues with emergency room staff and physicians. This real-time relay of information will allow hospital personnel to anticipate what’s coming in from the field. Moreover, edge computing and IoT systems will enable emergency medical technicians to access patient records from databases in real time. They will also be able transmit patients’ vital signs to hospitals while they are in transit, giving hospital staff the data they need to prepare for intake. This advance knowledge of the patient’s condition will allow them to have the right medical specialists and equipment on hand when the patient arrives at the facility.

When Milliseconds Matter

In these and other instances, edge computing reduces latency because data does not have to traverse over a network to a remote data center or cloud for processing. Depending on the implementation, time-sensitive data in an edge computing architecture may be processed at the point of origin by an intelligent device or sent to an intermediary server located at a data center in close geographical proximity to the client. As described above, this is ideal for situations where latencies of milliseconds can mean the difference between life and death, but also in machine-to-machine (M2M) industrial applications. Meanwhile, data that is less time-sensitive will be sent to the cloud for historical analysis, Big Data analytics and long-term storage. Augmented Reality (AR) and Virtual Reality (VR), multiplayer gaming and eCommerce will also benefit from the advantages of edge computing and IoT systems.

In addition to increased data speed through reduced computing latency, there are three additional reasons why edge computing will become essential to enterprise business operations and IT infrastructure in the age of IoT:

Locating the Edge and the Importance of 5G

Occupying the link between connected devices and the cloud, edge computing is comprised of local devices such as a network appliance or server that translates cloud storage APIs; localized data centers with one-to-ten racks that provide significant processing and storage capabilities, including prefabricated micro data centers; and regional data centers that have more than 10 racks and are located closer to the user and data source than centralized cloud data centers.

Another critical component that will facilitate edge computing will be the buildout of next-gen 5G cellular networks by telecommunication companies. In the U.S., both AT&T and Verizon are conducting local trials, and Japan, South Korea, and China are already building early-stage 5G networks. As telecom providers build 5G into their wireless networks, they will increasingly add micro data centers that are either integrated into or located adjacent to 5G towers. Enterprise and Cloud customers will then be able to own or lease space in these micro data centers for edge computing, then have direct access to a gateway into the telecom provider’s broader network, which could connect to a public IaaS cloud provider.

The Future of Next-Generation Communications

Representing a convergence that some believe is the future of next-generation communications, some tower infrastructure companies are already forging partnerships with enterprise-class data center providers to develop micro data centers at the base of communication towers that will enable edge computing. With this model, tower-based data centers bring the cloud into local areas and integrate with emerging C-RAN network architecture.

In addition to improving distribution for content providers and carriers, this method of edge computing architecture also creates an important distribution point for the cloud at a lower cost. Hence, there’s just one jump to the micro data center at the base of the towers, so not only is the latency for accessing the cloud reduced, but it opens the possibility for real-time applications and a richer more immersive experience for end users.

Recently, the industry has seen several partnerships and tests between mobile network operators (MNOs) and micro data center providers for their units to be used at cell tower sites. However, those companies that can leverage the complete trifecta of cell towers, a nationwide footprint of data centers and diverse fiber assets are best positioned to offer a platform for customers seeking a highly distributed colocation and connectivity solution in support of edge computing. Moreover, to deliver a truly valuable service to the customer, it’s not just about the towers, micro data centers and dense fiber routes pushing data, storage, and processing to the edge, but seamlessly orchestrating all of these elements to provide a fully managed end-to-end solution.

Frequently Asked Questions

Hybrid IT is rapidly becoming the technology strategy of choice for enterprises, in many cases to take advantage of cloud computing benefits while maintaining colocated assets. The impacts of digital transformation, as well as business growth, are creating the widespread need for hybrid IT across industries (Microsoft).

Over the past few years, the hybrid IT story has changed. The role and importance of hybrid cloud in modern IT infrastructure sits at the heart of the hybrid IT strategy shift. Its positioning started as a mode of conveyance from on-premise colocated assets to the cloud and evolved into a strategic business decision designed to provide enterprise flexibility. While it has its functional purposes, hybrid IT is a journey that requires specific skill sets to navigate the associated complexity. Compliance, security and the ability to draw the proper boundary around your IT systems all become more difficult in hybrid scenarios. When your boundary is virtual, it becomes necessary to raise the bar for compliance and security strategies, as well as advanced tools for properly visualizing IT systems.

Then there are the effects of the public cloud, such as Azure and AWS. While they’re being used with increasing frequency, these platforms aren’t necessarily amenable to your applications. Typically, companies need to save vast amounts of information, but putting that volume of data on a SAN is very expensive. Plus, while going straight to AWS can appear to save money, AWS doesn’t always speak the same language that your applications speaks. Cold storage is another option, but it’s not readily accessible. DataBank employs a Storage Gateway Solution that’s a combination of cache and a translator easing the pain of a hybrid transition to the cloud.

The latter is an example of how an experienced partner can alleviate the pain and cost of moving applications to the cloud, which is one of the reasons it’s rare to find an enterprise with an all-colocation or all-public cloud model. Hybrid IT models, anchored by hybrid cloud, are reshaping how enterprises plan and execute technology strategy. As such, IT professionals have to consider that different assets warrant investment in different products, but again, this introduces complexity into:

Controlling Hybrid IT Chaos: 4 Challenges and Solutions

1. Cost

Obviously, cost is a consideration for any technology strategy, often boiling down to a choice between CAPEX and OPEX. In the case of hybrid, this typically comes into play when aiming to move particular technology assets to the cloud.

However, given the associated complexity of hybrid, maintenance costs can increase when managing IT internally. This is where offloading your hybrid infrastructure can become an attractive option. If you’re struggling to hire the right talent for the continuous care and feeding of numerous application stacks, a service provider with greater scale could be a better option. Additionally, an expert hybrid IT partner can be thought of as a single location for managing thousands of servers—enterprises can reap the resulting cost savings.

2. Risk

Like we said, hybrid IT has become standard. It’s pretty much necessary in order to properly deliver services, but with its use comes an increase in compliance and security risks. The compliance consequences of hybrid IT are, of course, dependent on the industry and nature of your business. On a high level, having data in more places and under the control of cloud providers complicates things.

When it comes to hybrid IT, compliance standards aren’t consistent yet, but it seems that the direction is headed towards shared accountability between cloud providers and customers (CSO from IDG). It’s less pressure for enterprises, but there’s still the need to ensure service providers are experts on the rules.

Security in a hybrid environment becomes tricky, too. Traditional tools and practices don’t work as well when you have to integrate and manage a multitude of disparate products built for solving disparate problems. Dealing with hybrid security comes down to two primary challenges: 1) achieving comprehensive visibility into user activity and workloads and 2) finding a way to collect and analyze the data generated by such a widespread environment (CSO from IDG).

This is another opportunity to alleviate a hybrid pain using a reputable service provider. The real key is identifying a partner with a chief information security officer and dedicated security and compliance engineers. This will allow you to build both compliance and security into your hybrid configuration.

3. Scale

Hybrid IT can present an excellent opportunity to scale your environment, but the journey will present obstacles. Experience has proven that flexibility in scaling capacity across different data center environments is key to doing it effectively.

When integrating cloud with your on-premise colocated assets, it’s easier to deliver new capabilities to end users while managing cost. Hybrid cloud enables the ability to access resources on demand while getting the most of your current infrastructure. Keep in mind, though, that scalability isn’t an immediate benefit of a hybrid model if your solution isn’t managed properly. If you’re handling management in-house with limited resources, you may struggle to take advantage of the scalability opportunities the cloud has to offer.

If you’re looking to maximize scalability potential as much as possible, you’ll be better off partnering with a hybrid IT provider to ensure you’re taking advantage of both horizontal and vertical scaling opportunities.

4. Agility

If you’re succeeding at agility, then you should be able to onboard and deliver new technologies efficiently and with ease. Achieving operational agility also comes down to the right expertise and internal resources. With so much emphasis being placed on technological innovation, churning out interesting and useful solutions for your customers on a continual basis is now critical to competitive advantage. When executed on correctly, hybrid IT allows you to mix and match the precise combination of services that will help your business focus more on customer needs.

But you can’t be agile if you don’t have the proper resources. To maximize agility, your people, processes, technology, and economics have to be properly aligned. In many cases, this means consulting the appropriate hybrid IT expertise in order to ultimately improve business outcomes and operational efficiency.

You Can’t Escape Hybrid IT, but You Can Master It.

Digital transformation is inevitable, and hybrid IT is the optimal strategy to cost-effectively leverage the right resources for the right applications simultaneously. The problem is, it’s difficult, risky, and time-consuming to cover all of your bases when you’re running disparate environments, and there’s no way around that—so don’t go it alone.
