If you're a user of Google's cloud services and have ever been stuck, you're probably not alone. To solve these issues, Google has introduced a tiered support service that spans the range of possible needs for support. The starting price is a lowly $0, but this just means you have access to online documentation, forums, and billing support.
Step up one level and you'll be looking at $150 per month. For this, you'll get "direct access to [Google's] support team." Step up again and you're looking at $400 per month. For this, you will get 24x7 phone support and various other support services. Of course, if none of these meet your needs, you can contact Google and get a custom plan that will set you back an undetermined amount.
You can find out more about the different support options on Google's website.
