Advantages of AWS• Cost
• Spend 0 time on infrastructure
• High availability
• Scalability only limited by your wallet
• Performance
• Loosely coupled microservice-y pieces
• Fun!
Disadvantages of AWS
• Learning curve is steep at first
• If your AWS zone goes down, so do you (I’m looking at you, US-EAST-2 😡)
• Managing all these little pieces can be tricky Frameworks like ServerLess and apex can help with this
Finding Help
• @AWSSupport usually responds in a few hours.
• Amazon docs are, on the whole, very good.
