PaaS services fit in that world in between serverless and roll-your-own infrustructure.  AWS Elastic Beanstalk is a PaaS service exposes their their service usage to teach you the right way to deploy web applications. The EB team eats their own AWS dogfood and generates a full featured environment via a generated CloudFormation template that you can examine and leverage. For this example we will deploy Apache Tika document parser as a service. We'll leverage a previous blog article PaaS Document Parsing With Tika and EBS for the instructions.  A shortened version is below Topology Discussion This diagram shows the components deployed to make an autoscaling web application that leverages Elastic Beanstalk , IAM, ALBs and other AWS goodness. Resources and Services Elastic Beanstalk uses these services to provision and deploy a simple no-database web application like the Apache Tika Parser.  We use the CLI to upload the configuration which Elastic Beanstalk the...

You would size your instances appropriately for your largest documents.   Preconditions An AWS account. AWS ac...
