INTERNET OF THINGS Let’s take the example of a retail store. Until recently, there could have been a dozen point of sale (POS) cash registers, and a couple of desktop computers at the front of the shop used by managers to access the inventory system. Perhaps there were a few security cameras. Those devices connect to servers in a data closet running the commercial automation, inventory management and video storage applications. Data was batched and uploaded daily or weekly to a server over the corporate network. As we walk into a more modern retail store today, we see cash registers replaced by tablets equipped with a credit card reader and running a POS app. Store managers use scanners and other handheld devices to collect and access inventory data, and there are security web cameras. Those devices are often managed through a smartphone app and connected through a Wi-Fi access point directly with servers in the cloud. PC computers and closet servers are gone. In this scenario, there’s a migration of complexity from the edge of the IT infrastructure to the core. The link between the remote sites to the Internet becomes more critical, as each device is now dependent on its connection to a server in the cloud. Ensuring the resilience of your network is cr itical to support the distributed business. For implementers of enterprise IoT, that means a focus on connectivity and need for failover strategies to cope with link failures. IoT Data Explosion As the technologies mature and the enterprise use of the IoT multiply in the coming years, we’ll eventually see an explosion of data volumes generated and consumed at the edge of the network. Continuing with the retail store example, hundreds of price tags on the shelves can be replaced by smart tags that can be controlled remotely. Intelligence embedded in shelves and the products themselves will enable monitoring and management of inventory levels through a centrally deployed application, without human intervention. There will be sensors and beacons distributed throughout the facility to control and monitor everything – ranging from the customer movements and environmental conditions, to physical security etc. In this scenario it may be necessary to introduce new IT components closer to the edge of the network again to aggregate, filter, sort and analyse data to keep it from unnecessarily flowing to the core of the network. Those components might include mesh wireless gateways, data aggregators, local data storage, and analysis engines. In large IoT deployments, it might be necessary to deploy small data center-like infrastructures closer to the edge of the network. With more IT components at the edge, remote provisioning and out-of-band management technologies will be needed to minimise the cost of maintaining the IoT infrastructure in operation. With increased complexity, scale and dispersion of the IT infrastructure needed to support IoT applications, automation is an important component of the IT strategy. Take a long view Most analysis pieces on consequences of adoption of IoT in IT Infrastructure will focus on the end scenario where the technology is adopted and the use cases are fully developed. We suggest that, in a large development like IoT, it’s important to see through the hype cycle and note that this movement happens over a decade, not months. From the IoT adopter’s perspective, being aware of that can mean the difference between success and failure. For most enterprise users, adoption of cloud and mobile technologies and a focus on Network Resilience is the first step. As IoT adoption matures, the need to build additional infrastructure closer to the network edge and focus on provisioning, remote management and IT automation will become more important. n www.networkseuropemagazine.com 15
