Cloud infrastructure success is a fine balance of budget and service quality

The visual summary below is based on a post by Will Larson, who started the SRE function at Uber. His post elaborates on a “trunks and branches” model for developing infrastructure-facing teams.

It also covered an interesting perspective on the balancing act of budget and service quality. I will explain the visual summary underneath it.

Successful cloud investments are dependent on service quality and level of budget - both of which are susceptible to problems that can bust them

An explanation of the above visual summary

  • Long-term cloud infrastructure success depends on balancing both elements of high Service Quality and a reasonable Investment Budget
  • Service Quality can get torpedoed by morale busters like non-stop grunt work, not enough engineers, etc.
  • Investment budget can get torpedoed by continuously high cloud costs and an excess of branch teams working on problems that aren’t solving immediate problems
  • The key is to always keep an eye on these “busters” that can torpedo your long-term return on cloud investment
