Public Cloud’s Impact on Enterprise Networks
Corporations are moving to public cloud in growing numbers, and the increasing use of these services is having an impact on enterprise networks. Potential bottlenecks are shifting away from the company data center to network entry and exit points. Corporations must understand why the changes are occurring and their impact, and then take steps to ensure their networks deliver acceptable response times. Organizations are embracing cloud computing. Worldwide spending on public cloud services was forecasted to increase from $227.8 billion in 2019 to $266.4 billion in 2020, a 17% annual jump, according to market research firm Gartner, Inc. As workloads move from the company data center to the public cloud, enterprise network traffic patterns shift. The first change is corporations are deploying more applications: mobile, social media, data analytics, and artificial intelligence and machine learning. The result is they work with more information and need to carry it over their corporate networks. The volume of data generated annually is expected to grow from 33 zettabytes (1 trillion gigabytes) in 2018 to 175ZB in 2025, a Compounded Annual Growth Rate (CAGR) of 61%. Changing Traffic Patterns Faster networking techniques are required as more information flows over enterprise networks. Recently, vendors started to roll out Wi-Fi 6, which increases wireless networks’ top speed from 1G bps to 2G bps to 10G bps. In addition, traffic flows shift. In the past, processing was monolithic: almost all was done in central data centers. Cloud distributes computing infrastructure: keeping some work on site but moving some off to public [...]
