 ## Prerequisites
 
-Some configurations are required in your AWS account for this sample to work. Basically, an _S3 bucket_ (by default `spring-cloud-aws-sample` is used, but it can be changed using `cloud.aws.s3.bucket` property), and an _RDS MySQL instance_ open to the world. Additionally, we need an _IAM user_ with access key and programmatic access to AWS API so that we can access AWS resources from our development machine.

-### Create an IAM User
-
-* Enable programmatic access 
-* Generate an access key for the user
-* Give the user the following permissions:
-** AmazonS3FullAccess
-** AmazonRDSFullAccess

 **WARNING**: These instructions allow you to run and test the application from within your development environment (i.e., without deploying it to AWS) using an RDS instance open to the world, which is something you should avoid in production.

+### To run locally
+
+**Note**: I was unable to run new versions of spring-cloud-aws locally. It seems it tries always to perform some autoconfiguration assuming it is deployed on AWS, and as long as it doesn't find a valid instance id, it raises an exception and stops. What follows here is the approach that worked for version 0.0.1 of the tutorial, useless in version 0.1.0. If you have an idea of how this can be solved, please fill in an issue and I'll look into it.

+
+#### Create an IAM User
+
+* Enable programmatic access 
+* Generate an access key for the user
+* Give the user the following permissions:
+** AmazonS3FullAccess
+** AmazonRDSFullAccess
+
+### To run on EC2
+
+#### Create an IAM role
+
+Create an IAM role with the following properties:
+
+* EC2 role (i.e., a role to be attached to EC2 instances)
+* Policies:
+** AmazonS3FullAccess
+** AmazonRDSFullAccess
+
+#### Create an EC2 instance
+
+It has been tested with an instance with the following properties:
+
+* AMI: Ubuntu 18.04
+* Type: t2.micro
+* Storage: 20Gb
+* Security group: choose or create one with ports 22 and 8080 opened
+* Attach the IAM role created previously
+
+Once the instance has been started, ssh'd into the machine and issue the following commands:
+
+```
+sudo apt-get update
+sudo apt-get install openjdk-8-jre-headless
+``` 
+
+Then from your own machine, build the jar file and upload it to your EC2 instance:
+
+```
+mvn package -DskipTests
+scp -i <your key> spring-cloud-aws-sample-0.1.0.jar ubuntu@<your ec2 ip>:/home/ubuntu/
+```
+
 ## Run the application
 
+### Locally 
+
 For the impatient...
 
 	git clone https://github.com/codeurjc/spring-cloud-aws-sample
 	cd spring-cloud-aws-sample 
 	mvn package
 	cd target
 	java -jar spring-cloud-aws-sample-0.0.1-SNAPSHOT.jar  --cloud.aws.rds.dbInstanceIdentifier=springaws --cloud.aws.rds.springaws.password=<your pass> --cloud.aws.rds.springaws.username=springaws --cloud.aws.rds.springaws.databaseName=springaws --cloud.aws.credentials.accessKey="key" --cloud.aws.credentials.secretKey="secret"
+
+### On an EC2 instance
+
+If your EC2 instance has the appropriate role (see prerequisites above), and the jar file has been uploaded, the it can be run just by issuing:
+
+    java -jar spring-cloud-aws-sample-0.1.0-SNAPSHOT.jar --cloud.aws.rds.db-instance-identifier="springaws" --cloud.aws.rds.springaws.password="your rds password"
