Description

Discussion around content for the Architecture section of the guide.

Details:

Some suggested ideas and guidance for content in this section:

Architecture

A Look Back (Issue #55)

• n-Tier Architecture
• SOA
• Microservices Architecture

The Serverless Architecture (Issue #54)

• Why do we need a new architectural pattern?
• Functions as a Service (FaaS)
• How do we get there?
  • Need for agile development lifecycles
  • Need for independent teams working in parallel
  • Focus on building than managing infrastructure

Patterns for Partitioning Code (Issue #53)

• Nanoservices
• Microservices
• Monolithic
• GraphQL

Notes that I took while chatting with @rupakg

Target audience

A-level, C-level
developers, devops

Introduction

• SOA -> microservices -> functions (serverless)
• serverless is like microservices but more granular
• serverless architecture: FaaS for compute, BaaS (backend-as-a-service) for everything else (DB, search, cache, CDN)

How serverless architecture looks like?

• serverless architectures are opinionated microservices architectures
• different serverless arch:
  • greenfield - the whole system in functions
  • adding features to a legacy system with functions (communication via SDK faster, or API Gateway endpoint - latency issue)

Challenges

• cold start
• API Gateway latency
• invocation limit
• distributed tracing
• centralized logging

Migration

• from traditional SOA architecture
• from microservices architecture
• grouping function is good (they can use the same DB)
• taking out functionalities from the existing system
