Businesses in Asia Pacific (APAC) are actively considering increasing their investments in networking technologies based on the cloud. In a study by technology analyst firm IDC they claimed that worldwide SD-WAN infrastructure and services revenues will grow at a compound annual growth rate (CAGR) of 69.6%, to reach $8.05bn in 2021.
