Twin sons of different mothers latency and bandwidth 2
- 1. Twin Sons of Different Mothers: Latency and Bandwidth Chris Crosby, CEO, Compass Datacenters
- 2. Related, But Not the Same
- 3. The Impact of Latency • Study by Akamai • 1 second delay in page load speed • 16% drop in customer satisfaction • Rich packet applications are more demanding • Ex: Netflix • IoT • “Instantaneous” packet processing • Critical for many applications • Ex: Real time inventory • Data reads and writes • No such thing as a multi-availability zone public cloud database 3
- 4. The Latency Factors 4 • Distance and contention
- 5. Latency: Factors • Operational requirements • Ex: Hypervisors add overhead to transmission speed • Contention for bandwidth (Public clouds) 5
- 6. Solving the Latency Issue • For now it’s geographical • Moving data as close to the end user as possible • Edge data centers • Emerging • Micro datacenters • Cisco FOG architecture • Any device can be a data collection point • Must have computing, storage and network connectivity 6
- 7. Insufficient Bandwidth • IDC • “50% of existing networks will be bandwidth constrained as a result of IoT” 7
- 8. The Traditional Network • Access via public means • Internet • Too many “chokepoints” 8 Source: Forrester
- 9. An Alternative Approach • Presented to a Compass customer • Direct Peering • Direct cloud connectivity • Eliminate public internet 9 Graphics courtesy of Equinix Internet Campus DC1 DC2 AWSEQIX DC Cloud Exchang e Internet Exchang e I2 Provider AzureI2
- 10. Eliminate the Internal Bottlenecks • Network only as fast as slowest component • Backplane contention • Considerations: • Top of rack switching • Faster switches • 10, 25, 40, 50, 100GB 10 Graphic courtesy of Mellanix
- 11. Summary 11 • Speed of delivery will only continue to grow • Lower latency • Higher bandwidth speeds • The important question: • Can the network support what you want to do? • Must eliminate contention/chokepoints • Internal and external • Failure to do so will result in: • Ineffective operation • Customer dissatisfaction • Must find partners agile enough to quickly adapt
