The best option for determining whether the increase in availability is worth the investment for a single year of usage is to calculate the value of improved availability to be $900, and determine that the increase in availability is not worth the investment. To calculate the value of improved availability, we can use the following formula:

Value of improved availability = Revenue * (New availability - Current availability)

Plugging in the given numbers, we get:

Value of improved availability = $1,000,000 * (0.9999 - 0.999) = $900

Since the value of improved availability is less than the investment of $2,000, we can conclude that the increase in availability is not worth the investment.

 The most efficient way to build an automated pipeline that deploys the application when the image is updated is to use Cloud Pub/Sub to trigger a Spinnaker pipeline.
