was it just a cost thing that would prevent people from just adding another server in to the mix? given that 4 was the magic number, add another server or two to add buffer to time between servers dying and 'it all breaks'? I'm realizing the cost factor may have been it, depending on size/location/etc. - would there be any other reason?
- Beltiras 7y agoMight have been tried and not worked. Might have been a limitation in scaling (f.ex. only being able to do master-slave replication and not being able to add more master nodes). Remember: it's bad software to begin with.
- jasonlotito 7y agoNot necessarily the reason here, but to answer your question: "would there be any other reason?" Another reason is backend constraints. Adding another server might simply cause more pressure on backend systems like a database. So they can't simply add more servers, as then the additional load on the database might cause that to crash, and result in even longer downtime.
