“Fail Fast and Learn Fast” with Cloud is a bad idea because Cloud overall is like a double-edged sword: when used correctly, it can be of great use, but it can be lethal if misused. In this meetup, Sudeep Chauha - founder of the ToMilkieWay.com shared his “near business death” experience after a GCP experiment ended up with a $72,000 bill shock. Infinite Recursions are a common problem, so this talk is useful to developers from any public Cloud. Sudeep explained the mistakes he made, and the lessons he learned - so the rest of us can avoid similar near-Bankruptcy incidents. Thank you, Sudeep! P.S.

3. Serverless Evolution (since FaaS started)
3
Serverless is New Agile & Mindset
#1 We started as Back-
end FaaS (Serverless)
Developers who enjoyed
“gluing” other people’s
APIs and Managed
Services)
#3 We're obsessed by
creating business value
(meaningful MVPs,
Products), focusing on
Outcomes – NOT
Outputs, and we mesh
well with Product
Managers
#2 We build bridges
between Serverless
Community (“Dev leg”),
and Front-end, Voice-First
& UX folks (“UX leg”)
#4 Achieve agility NOT
by “sprinting” faster
(like in Scrum), but
working smarter (by
using bigger building
blocks and less Ops)

4. Disconnect between IT & Business needs
4
How to help companies accelerate?
Technology is not the point => We are here to create Value
Adopting Serverless Mindset allowed us to shift the focus from “pimping
up our cars” (infrastructure/code), towards “driving” (the business) forward.

5. Covid-19 brought uncertainty to IT
5
Let’s Help one another as a Community
Yes, Cloud Computing is more
important than ever, but
1. most of you have to work longer
hours, many had to accept
“temporary” pay cuts, or both!
2. If takes longer to find work, and
3. if you are contractor, your
engagements are getting shorter.
On the flip side, COVID opened
possibilities for remote Cloud jobs
anywhere in the world... so

6. Community maturing into Consultancy:
6
Let’s Help Businesses propel into Clouds
1. Keep growing our Community of
Cloud Experts… with more relevant
Business-focused topics
2. Start offering Cloud Consulting
services… for free, then for-Fee
3. Start offering “matchmaking”
services… to connect Cloud experts
with Employers
4. Employers will get priority access to
the pool of Cloud Pros, regardless of
how short (or long) they'll need us
for… so

12. My team “Burnt $72K testing Firebase + Cloud Run and
almost went Bankrupt”. Blog posts below:
○ Part 1
○ Part 2
Background : What Started This

13. tl;dr 1
- Experimented with Cloud Run while building Announce
- Comparable to Amazon Elastic Kubernetes Service
- Without a great understand of Cloud
- Fail fast approach to learning Cloud

14. tl;dr 2
- Triggered infinite recursion on 1000 instances
- Thanks to “Background Processes”
- Caused 116 Billion Firebase Reads
- Thousands of hours of Cloud Run

15. tl;dr 3
- Instances scaled so rapidly, GCP billing notifications didn’t trigger in time
- Got billed $72K within few hours of service test
- Bill came after 2 days and blocked all our credit cards
- Wrote a lengthy doc for Google engineers, explaining why it’s not just our fault
- After ~10 days, some back and forth GCP let us go.

18. How to use Cloud and
Sleep Well

19. Full Blog Post:
sudcha.com/guide-to-cloud

20. 1. Use multiple forms of payments,
preferably with spend caps

21. 2. Setup Service Quotas

22. 3. Cloud Monitoring

23. 4. Spend good amount of time
understanding and predicting
costs

24. 5. CICD = Operational Efficiency
Time spent in CICD is like time spent in converting cube into sphere.

25. 6. Use Free Projects
To power multiple environments

26. 7. Multi Cloud

27. 8. Protect the keys!

28. - Code Repositories
- Access Tokens
- Deployment Keys
- Deployment Permissions

29. 9. Read “Best Practices in XYZ
Service” before deploying it

30. 10. Billing Budget Alerts /
Notifications
