Adjustments To Web Cluster For Elections
Notes about the adjustments to the Web cluster for elections seasons.
2015 Out Of Season
During the 'regular' part of the year where we experience fairly low/average traffic(other than some spikes here and there) the setup is kept fairly small.
| Qty | Use(s) | Instance Type | Details |
|---|---|---|---|
| 2 | Multi-Purpose | c3.2xlarge | 8 cores, 15GB RAM, 2x53GB EBS volumes |
2015 State Elections(No Federal)
This is all state and local elections. Traffic will generally be lower than a federal elections, but some scaling should happen.
For very heavy load times, the ratio of web to db servers will be 2:1.
| Qty | Use(s) | Instance Type | Details |
|---|---|---|---|
| 2-4 (dependent on demand) | Web | m4.xlarge | 4 cores, 16 GB RAM, 1x30GB EBS volume |
| 2 | Database | c3.2xlarge | 8 cores, 15GB RAM, 2x53GB EBS volumes |
Web Heads
Web heads will be setup to utilize a TON of RAM for caching and processes/threads will be 10x5 instead of 5x5 that we run during most of the year.
Database
The multiN servers will be re-purposed into database servers. Web servers will be disabled and Postgres will be configured to utilize a lot more memory. Redis configuration is likely to stay the same.
