It is well known that hardware advances always precede advances in software technology, and this is especially true for Oracle. As hardware becomes faster and cheaper, Oracle professionals change the ways in which we process information. Changes in hardware affect the way we design databases, the way we implement database and most importantly, the way that we tune databases.
While the costs of a DBA have remained relatively constant over the past 30 years, the costs of hardware have fallen dramatically, leading to a condition where applying hardware resources is often faster and cheaper than applying human resources to fix an acute performance problem.

This change in the costs of people vs. hardware has led to a technique called "throwing hardware at a problem". Even though hardware may not address the root cause of an acute performance problem, it's often the smart thing to do for these reasons:
* Hardware upgrades can be done fast, in just a few hours. Root cause fixes can take months.
* Hardware upgrades have very little risk. Re-designing an Oracle system can be very risky.
* Hardware upgrades are a cheaper, guaranteed fix. You can cache a 100 gigabyte database on SSD for under $100,000, while a root cause fix may cost millions of dollars.
