Cloud computing is a set of managed services. Your choices reduce work and help you scale.
Start simple. Use a single virtual machine or a container. Use Railway or Fly.io for early apps. Use serverless for unpredictable traffic. Do not optimize for scale you do not have.
Pick your tools wisely:
- Serverless functions: Use for short tasks.
- Managed databases: Use to save time.
- Object storage: Use for user files.
- Message queues: Use to prevent data loss.
Watch your money. Cloud bills surprise startups. Set budget alerts. Review unused resources.
Stay portable. Design your app to move between AWS, GCP, and Azure. This gives you leverage on pricing.
Plan before you code:
- Sketch the architecture on a whiteboard.
- Find failure points.
- Build the core path first.
- Add error handling later.
Avoid these mistakes:
- Over-engineering for future growth.
- Ignoring observability.
- Poor logging and metrics.
Professional tips:
- Use idempotency keys to stop duplicate requests.
- Use database transactions for data safety.
- Create screen-level APIs to reduce network calls.
Your action plan:
- This week: Audit your backend for logs and error handling.
- This month: Try one new pattern like a message queue.
- This quarter: Automate your deployments.
