Next-Generation E-Commerce Architecture and Core Commercial TB-Scale Database Migration to Cloud 新一代電子商務架構與核心商用TB級資料庫的雲端遷移 Level: 200, 中文演講 講師: Ryder Wang, Business Development Manager, AWS & Jerry Hou, Vice President of Information Services, PayEasy 對於電子商務 (E-Commerce) 平台來說，每年的特殊節日、促銷活動，都是達成創新高的交易量的重要時刻。然而，要能因應大幅提高的平台流量，背後有一個靈活、可快速擴展、穩定的基礎設施架構作為支撐，便是關鍵。此次分享中，我們會介紹如何使用 AWS 的服務來打造新一代可快速高度擴展的電子商務雲端架構，以及如何遷移核心的商用 TB 等級資料庫 (如：Oracle Database) 到雲端。同時，AWS 此次也特別邀請到台灣最大企業福利平台、全台擁有超過402萬會員並服務超過400家企業的 PayEasy，來分享 PayEasy 如何從專案測試、災難復原 (Disaster Recovery) 到生產環境的一步一步上雲之旅，以及 PayEasy 如何克服挑戰，將核心的商用 Oracle Database 搬上 Amazon RDS 的過程。 聯繫銷售: https://aws.amazon.com/tw/contact-us/ 與銷售線上聊天: https://pages.awscloud.com/tw-hkt-sales-chat.html

Ecommerce: it’s hard (and it’s getting harder)
Scale is different between customers …

6. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Scale: legacy ways of solving it
Buy new servers
Refuse connections
Build a bigger monolith
Tell your business you cannot do more
“We have to find a better way for it”

Why build your next-generation ecommerce?
• Pressure from the business to change
• We cannot change the website for six
months
• Lots of businesses are extending their
freeze period
• Scale
• Agility
• Lots of smaller changes => better
uptime and knowledge of your system

Architecture principles for next-gen ecommerce

10. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Architecture design implementation
These principles lead to some choices to make on implementation:
- Compute
- Where and how to run your ecommerce application?
- Decoupling/Messaging/Event Sourcing
- Exchange of the event objects, Amazon Simple Queue Service (Amazon SQS), Amazon MQ,
or Amazon Kinesis?
- Storing/Database
- Which object store or database to choose?

11. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Compute for ecommerce applications
Principles:
- Flexible
- Massive scale
- Cost-effective
- Efficient code delivery

12. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Decouple
Principles:
- Loose coupling
- API or messaging as a pattern
- Business functions: one at a time

13. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Next-gen ecommerce architecture: decouple

14. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
“The fundamental idea of event sourcing is that of ensuring
every change to the state of an application is captured in an
event object, and that these event objects are themselves
stored in the sequence they were applied for the same
lifetime as the application state itself.
- Martin Fowler

Event sourcing

15. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved.S U M M I T
Event Sourcing E-commerce
Principles:
- Event object: Everything must be captured as an event
- Kinesis or SQS
- Stored in S3
- Sequence: Event objects must be stored, queryable and
re-playable
- All events in S3: good news, you can query them directly (Amazon Redshift,
Amazon Athena, Amazon EMR, etc. )
- Snapshots (on schedule): limit the replays
- Reverse dependencies

將Production環境上AWS的原因：減輕財務投資、優化資源運用
背景
目標
困難
解決方案
機器即將到使用年限
評估未來2-3年需要的IT資源，需要編列約2000-3000萬來添購實體機器
減輕財務投資、降低人力維運成本、降低延遲、提昇效能、將資源投注於更有價
值的領域(如：向供應商爭取價格優惠，為會員帶來更好的購物品質)
購買實體機器的費用以及後續維運人力，都是較大的資本支出
將營運端的生產(Production)環境搬遷上雲
