I have been working with a start up customer that has a very limited budget but need resilliancy – in otherwords can not afford down time. I a previous iteration the CEO and I built a Paymetns Gateway and used the F5 GTM to provide Geographicly diverse failover capability and it cost big $$. So natrually he wanted it yesterday and for nothing… 🙂
What we had
- Production site in a Data Center in one US State
- DR site in another US state
- Abiltity to program a valid transaction to enure end to end availability
What we wanted:
- Active monitoring of web stite
- Failure notification
- Multiple sites to monitor from –
- Automatic failover to DR site
- Automatic Failback to Prod site when test is clear.
What I found – DNS Made Easy – Made it very easy to do exactly what we needed. I wont go into all the details but check it out – if you need to set up failover autmatic or manual I can not recomend them enough!
