Pardon my ignorance in this matter, but hasn't commoditized, scalable hosting (such as Amazon EC2) largely mitigated the issue of service degradation?

- sokoloff 17y agoOnly if every part of your system is perfectly horizontally scalable. There are very frequently some singleton aspects of a system, perhaps the most common example being a single central data store with a fan out of web servers. The web servers scale by adding more, but it's an architectural change to add a second DB.
- blackcat786 17y agoExactly. There is always a "deployed system limit" even in horizontally scaling DB layers as deployed with sharding etc.
