The Internet of Things (IoT) is more than just the rapid expansion of sensors. It's about how data is generated, processed, and utilized in real time. As we look ahead, the evolution of storage technologies gives us a glimpse into what the future holds for IoT. One thing is certain: the volume of data and traffic will grow exponentially.
While IoT data is often considered unstructured, many data streams actually have their own internal structure. A lot of this data is only used once before being discarded or archived. The challenge lies in managing this massive influx of information efficiently.
One key aspect of IoT is the need for near-real-time processing. For example, when you're shopping, your location can be tracked to deliver personalized ads. These ads must be delivered within just 1–2 seconds to be effective. This level of responsiveness demands fast and intelligent data handling.
Most IoT data is "processed" as it enters the data center. For instance, facial recognition data might be converted into a location tag. Raw data is stored temporarily, depending on its purpose, and may eventually be moved to disk storage. The processed data, however, becomes a more valuable stream that can be analyzed further.
This refined data is then fed into powerful analytics engines that use big data technologies to derive insights. These engines typically rely on in-memory databases with large amounts of RAM, multiple processor cores, and high-speed SSDs via PCI-E interfaces. Data is either loaded directly into memory or stored via SSD for quick access. GPUs, combined with frameworks like Hadoop, enable fast parallel processing, such as rapid data searches.
Once processed, the data is transferred to SSDs and stored in a hierarchical storage system. The data center will host numerous data ingestors and analysis engines. Mass storage will evolve into scalable object storage systems with advanced compression, deduplication, and support for 10 TB drives. Network performance will also improve significantly, moving from 10GbE to 25/50GbE standards. Aggregated bandwidth will increase tenfold, and the backbone network will shift toward 100GbE as the new norm.
In the coming years, the number of connected devices will explode. From smart billboards and automated toll systems to intelligent signage, nearly every device will be part of the IoT ecosystem. This transformation will require robust infrastructure, faster networks, and smarter data management to handle the growing demand.
