Sample Configuration of a Current ‘state of the art’ DNS Solution
One DNS system « state of the art » will deliver a DNS traffic of 1Mrps.
To deliver a DNS request throughput of 150 Mrps the investment needs is about:
- 150 independent systems (average cost of $ 4,000 each),
- One load balancer per systems (assumption based on F5 solutions costs about $20,000)
- Overhead costs (square feet, power supply, management and security) estimated to be circa 20% of total costs.
Total estimated costs would result in:
| Systems :150 * $ 4k (2 links 10Gbps each |
= $ 600,000 |
| Load balancer (F5) : 150 * $ 20k | = $ 3,000,000 |
| TOverhead costs (20%) | = $ 720,000 |
| Total cost | = $ 4,320,000 |
CONCLUSION:
with the “state of the art” solution the total investment required to drive 150 Mrps is $4.320,000; the average per Mprs cost in this configuration is $ 28,800 /Mrps
dnRunner Benchmark Configuration
The equipment used for dnRunner’s benchmark delivers throughput performance of 150 GBPS
| One system (four E7-4890 v2 ) | =$ 40,000 | ||
| Overhead costs (20%) | =$ 800 | ||
| Total cost | =$ 40,800 |
CONCLUSION:
with dnRunner the investment amount required to drive 150 Mrps is $ 40,800; the average per Mrps cost of using this configuration for dnRunner is $ 320 /Mrps
Cost of Ownership Comparison Charts
Based on dnRunner’s performances that were controlled by a benchmark , an estimated of savings for an Internet player who needs to deliver traffic of 1000 Mrps the total investment savings could reach $28,500.000.
