Spending on Internet of Things (IoT) will reach $1.3 trillion by 2020, and the processing of 43 percent of this data will be at the edge, according to IDC projections. The number of “connected things” will reach 30 billion in 2020 and jump to 80 billion in the following 25 years, the research firm predicts. This market demand is driving the need for new solutions like edge computing.
Historically, the primary point of IT has swung between the focus on a centralized model and a decentralized one. It started with centralized mainframe computing, then moved to decentralized client-server networks, and then back again to a centralized model in the cloud. Now, the time for the pendulum to swing back to a decentralized model has come in the form of ‘local edge computing.’
