2. Use Cases 0 0 0 0 ___ Cautions Agenda
5. Products API Customers API Transactions API Orders API Deliveries API Microservices Monolith Application
6. Products API Customers API Transactions API Orders API Deliveries API Microservices Expectation
7. Products API Customers API Transactions API Consumers face a lot of challenges Orders API Deliveries API o X X ___
8. Multiple Retrieval + Attack Points 0 0 0 0 ___ Multiple Domain Names, SSL Certs and CORS http://foo.com http://bar.com http://ses.com Authentication Hell Client-side Issues
9. Products API Authentication Rate Limiting Logging Orders API Authentication Rate Limiting Caching Transactions API Authentication Logging Caching Clients / Consumers Inconsistencies and Duplications
10. To solve these, API Gateways are introduced
11. Products API Customers API Transactions API Orders API Deliveries API Stocks API API Gateway API Gateway to the Rescue
12. Do you mean a Reverse Proxy?
13. Proxying is one of the jobs of a gateway. API Gateway Authentication Rate Limiting Logging Reverse Proxy Caching Monitoring Tracing Authorization Authorization
14. Centralized Cross Cutting Concerns API Gateway - Logging - Authentication - Rate Limiting / QOS - Licensing - Monitoring - Tracing
15. Faster Cross- continental calls due to Response Aggregation
16. ASIA Europe Cost of Communication 55 MS Latency SSL Handshake
17. Consumer ASIA Europe Products Transactions Users Latency of 55 MS 55 MS x 3 = 165 MS Total Response Time W/O Gateway
18. Consumer API Gateway ASIA Europe Products Transactions Users Latency of 55 MS Latency of 2 MS With Gateway Asia to EU = 55 MS EU to EU = 2 MS x 3 instances TOTAL Response Time = 61 MS
