Although I can't help but wonder.. if you have a read and write database used by almost any page you serve, wouldn't you say both assertion below are true?


  • since the DB is read/write you can't spawn multiple copy of it on multiple server
  • since this one server is used for all your queries, you can't really scale your website


All of that is irrelevant if the business doesn't have the traffic to require multiple servers. In that case a hosting company (cloud service) is just providing the expertise to keep that single server up an running all the time. You are responsible for the data but not the box, operating system and perhaps not even the database software.

But if the business does have enough volume then the business itself drives what the specifics are of how the volume can be handled.

If a Point of Sale device is ringing up a transaction in Los Angles then there is no overlap between that transaction and one at the same time in Tampa Bay. The cashier is different, the customer is different, the fulfillment center is different. Same is true for medical, construction, movie theaters, etc.

As one design consideration a smaller company can make if they actually have the volume is that replicated servers do not all need to be read and write. It is likely that many more transactions will be reads rather than writes. So most can be read only. That reduces load on the write server, often significantly. Writes are replicated to the read servers.

That leads to the design consideration of timeliness. Does a new user that was just created in New York (east coast server) need to actually be visible to the user in California (west coast server) immediately or is 5 seconds later good enough? After all the customer service rep that created that user probably needs to do some stuff before they even tell the user it is working. And that will take more than 5 seconds.

Naturally very large businesses have much more complicated design problems that they must deal with. But companies can get by with must less complications for quite a long time before they encounter those problems.
