But

Drupal is hard

Hard to learn

…many concepts

Hard to develop

the code is too complex

Hard to debug

1. large code base

2. Complex sub system (views, ctools, …)

3. Low quality modules

Hard to build product

1. Hire good developer

2. Scale

3. Deploy

4. Many modules for a single Drupal site

Examples

• Amazon web services: S3, SQS, …

But

Dependency

1. A service that depends on other service
2. A service may down, other should work
3. queue/worker

Separate the data

1. The object should be stored in single tables
2. Don't use JOIN queries.
3. Demo: http://staging.mygo1.com/webapp/#/app/reports

Monitor

Just use pingdom, cloudwatch, …

Internal network

Just use Consul

Authentication

1. Problem: The services does not understand who is requesting
2. Solution: JWT
3. JWT:
   1. HEADER.PAYLOAD.SIGNATURE
   2. HEADER: Information about the string
   3. PAYLOAD: Main data
   4. SIGNATURE: Make sure the JWT is not changed

Conclusion

Study the architect, don't study the tool/framework
