Serverless Anna Su Send Email and update status
Why not VM 即使 server 沒有收到任何 request ,還是會被收取費⽤用 必須設定與持續管理理 Server
需要經常更更新 Server,避免安全性問題 當我們使⽤用量量變⼤大時,需要管理理 server 的 scaling up 如果使⽤用量量變低時,也需要 scaling down
Why Serverless ⾃自動擴展 依照使⽤用量量付費 開發速度更更快 零管理理
You don’t have to think about those servers. You just
focus on code.
What’s Serverless Serverless is an execution model where the cloud
provider is responsible for executing a piece of code by dynamically allocating the resources.
What’s Serverless The code is typically run inside stateless containers.
Can be triggered by a variety of events including http requests, database events, monitoring alerts, file uploads, scheduled events, etc
How Serverless Works @aws Upload your code to AWS Lambda
Set up your code to trigger from other AWS services, HTTP endpoints, or in-app activity Lambda runs your code only when triggered, using only the compute resources needed Pay just for the compute time you use
Install Serverless npm install -g serverless
Deploy a Node.js function to AWS Lambda
sls
sls create -t aws-nodejs
brew install awscli
aws configure
module.exports.hello = async (event) => { return { statusCode: 200,
body: JSON.stringify({ message: 'Go Serverless v1.0! Your function executed successfully!', input: event, }), }; }; handler.js
service: aws-nodejs-demo provider: name: aws runtime: nodejs8.10 functions: hello: handler:
handler.hello events: - http: path: / method: get serverless.yml
