A new study by Cisco confirms what we expected; cloud based data center traffic will continue to increase, growing at a rate of 33% a year from 2010 to 2015.
Here’s some interesting items from the Study:
- From 2000 to 2008, peer-to-peer file sharing dominated Internet traffic. As a result, the majority of Internet traffic did not touch a data center, but was communicated directly between Internet users. Since 2008, most Internet traffic has originated or terminated in a data center. Data center traffic will continue to dominate Internet traffic for the foreseeable future, but the nature of data center traffic will undergo a fundamental transformation brought about by cloud applications, services, and infrastructure. By 2015, one-third of data center traffic will be cloud traffic.
- In 2011, global average download speeds are 4.9 Mbps, with global average fixed download speeds at 6.7 Mbps and global average mobile download speeds at 3 Mbps. Global average upload speeds are 2.7 Mbps, with global average fixed upload speeds at 3.7 Mbps and global average mobile upload speeds at 1.6 Mbps. Western Europe leads in overall average fixed and mobile download speeds of 12.5 Mbps, with Central and Eastern Europe next with 9.3 Mbps.
- Western Europe leads in overall mobile download speeds of 4.9 Mbps and North America closely follows with 4.6 Mbps, making them the most cloud-ready regions from a download-speed perspective.
- Overall average fixed and mobile global latency is 201 ms. Global average fixed latency is 125 and average mobile latency is 290. Western Europe leads in fixed latency with 63 ms and North America closely follows with 75 ms, making these two regions the most cloud ready from a fixed latency perspective.
- All of the regions have some level of cloud readiness based on their average upload/download speeds and latencies, as shown in Figure 15. Asia Pacific, Western Europe, North America, and Central and Eastern Europe are better prepared for the intermediate cloud applications such as streaming high-definition video.
