Here are some cloud design patterns that you should know as a senior engineer:


15. Retry Pattern:
Automatically retry failed operations to improve the chances of success.

14. Cache-Aside pattern:
Loading data into a cache on-demand to improve data access times and reduce server load.

13. Blue-Green Deployment pattern:
Deploying a new version of an application alongside the old one for easy rollback in case of issues.

12. Ambassador pattern:
Proxy managing communication between microservices.

11. Backends for Frontends pattern:
Specialized backend services for different user interfaces (frontends).

10. Bulkhead pattern:
Isolating components to prevent cascading failures in a system.

9. Circuit Breaker pattern:
Limiting requests to prevent system overload during a failure or downtime.

8. CQRS pattern:
Separating read and write operations for improved system scalability.

7. Event Sourcing pattern:
Capturing and storing every state-changing event for data reconstruction.

6. Materialized View pattern:
Precomputing and storing query results for faster data retrieval.

5. Publisher-Subscriber pattern:
Communication pattern where senders notify many receivers.

4. Rate Limiting pattern:
Restricting the rate of incoming requests to a system.

3. Saga pattern:
Coordinating a series of transactions to maintain data consistency.

2. Sidecar pattern:
Independent service extends the functionality of a main application.

1. Throttling pattern:
Controlling the rate of processing to prevent resource exhaustion.


Build reliable and scalable applications by studying proven cloud design patterns.

I spent 1+ hour studying how Stripe prevents double payment, so you don't have to.

Here's a summary of what I learned:


- They use an idempotent API to avoid double payment

- They use UUID as the idempotency key

- They send the idempotency key via HTTP headers

- They create a new idempotency key whenever the request payload change

- They store the idempotency keys in a database on the server side

- They query the database with keys to check if a request was processed earlier

- They process a request only if it's new and then store its idempotency key in the database

- They roll back a transaction using the ACID database on a server error

- They remove the idempotency keys from the database after 24 hours for reuse

- They use exponential backoff with jitter to avoid the thundering herd problem


PS - I wrote a detailed post with visuals of this case study in my newsletter:
