Conclusion

Failover mechanisms are neither an extra effort nor an extra cost that can be ignored in software solutions. From the developer’s perspective failover mechanisms are a sign-off:

• Understanding of working environment of a specific piece of code,
• Willingness to supply a reliable and robust system,
• A way to avoid irresolvable issues.

On the other hand, for the client requesting a software solution, failovers can:

• Minimise the problems from ignored or removed requirements,
• Provide a reliable and robust system that will reduce the impact of business loss,
• More importantly, the solution purchased is less susceptible to errors leading to business problems.
