Data Center Knowledge recently highlighted some key statistics from Cisco’s Global Cloud Index that are worth repeating. Our partner, Cisco, delivers this annual index as a means to guide data center decisions by analyzing trends in network traffic, and this latest index is eye-opening.
Between 2014 and 2019, data center network traffic is expected to rise 300 percent, with global cloud traffic expected to rise over 400 percent during the same period. Cloud application use, BYOD, social media, and even IoT to some extent are all contributing to the accelerating pace of data creation.
- The total volume of data center traffic projected for 2019 is 10.4 zettabytes (Note: a zettabyte has 21 zeros in it or 1 trillion gigabytes).
- The total volume of data center traffic in 2014 was 3.4 zettabytes.
- The total volume of cloud traffic projected in 2019 is 8.6 zettabytes.
- The number of workloads per physical server in cloud data centers in 2019 is expected to be 8.4, which is up from 5.1 in 2014.
- 56 percent of the workloads running in public data centers in 2019 will be cloud based, which is up from 30 percent in 2014.
- The amount of traffic that will be generated in 2019 traveling to, from, and between all datacenters is the same as if the entire world’s population streamed music for 26 months straight.
It’s clear that cloud usage is growing and will continue to grow – inside and outside of your organization’s IT reach. Before the cloud causes disruption to your organization (data loss, theft, or breach as example) answer these ten questions to help guide a cloud computing policy:
- Which devices will be allowed in your organization for work (or non-work)?
- What company data can be accessed and by whom?
- What apps will be allowed?
- Will password logins be required?
- What will your IT support cover and what will it not?
- Do you know your legal implications of a data breach?
- Are you thinking far enough into the future?
- Have you established data use policies?
- Have you factored in time and bandwidth requirements?
- Have you looked internally for better efficiencies?
The cloud is here to stay but that doesn’t mean that it needs to take over. Given Cisco’s future predictions for cloud growth, the time to tackle cloud proliferation is now.
