Let’s Send Some Tweets With Lambda
Okay, so now is finally the point where this Twitter thing comes together. In this section, we’ll process the user’s authorization to have them follow us, as well as send them a tweet stating that they are successfully signed up!
Email, Lambda, Mailgun, Dynamo, S3
There is going to be a lot coming at you all at once in this post. This is a large project with a lot of moving parts; while I actually built this incrementally, we’ll just be building pretty much everything final-stage here (with a few exceptions). Take your time and read everything. We’ll be touching S3, Lambda, IAM, KMS, and DynamoDB services in this post.
