IBM just agreed to spend $34 billion on Red Hat, the largest software deal ever. It's by far IBM's biggest deal in its 107-year history and follows five straight years of declining revenue at the company.

There's no guarantee such a big bet will pay off. Spending this much won't suddenly vault IBM past Amazon in the public cloud market or turn it into a trendy software growth story like Salesforce or Twilio.
