Common Concerns

Security

The State of Serverless Security Fall 2017 by @marknca

Security

• Automated Cloud Governance
• Real time compliance
• Check out Cloud Custodian by Capital One

What about 3rd party High Level Services?

Not Invented Here

Embrace the world of Service-ful

Vendor Lock-In

• Functions are different to VMs in a Service-ful, API driven world
• Lambda complements AWS solution. Not the other way around
• Pick a Cloud, or two and leverage the best Services they offer
• A Multi Cloud situation Functions can still call APIs or SDKs
• Serverless Framework can help to migrate if/when necessary

Demo

The Code

> npm install -g serverless
> sls install \
    -u https://github.com/serverless/examples/tree/master/aws-node-rest-api-with-dynamodb \
    -n todos-api
> cd tods-api
> npm install
> sls deploy

We will build and deploy a similar API to the Users API that was hacked together during Iot Hackathon at ServerlessConf NYC 2017

Conclusion

• Serverless empowers cheaper, faster and focused business features to market
• Lambda is a powerful tool for AWS-centric solutions

In the next talk, I will dive into detailed

implementation and overcoming practical challenges
