## CHOREOGRAPHY Pattern - AWS Serverless - Java
2+
3+
This is a Java implementation of the CHOREOGRAPHY Pattern using AWS Serverless services.
4+
5+
<img src="choreography.png" alt="" width="50%"/>
6+
7+
#### Description
8+
9+
This is a basic representation and implementation of the Choreography pattern.
10+
In Microservice architecture the application is divided in small services which are responsible for a singe business subdomain.
11+
When these services need to communicate with each other there are several ways and different communication styles.
12+
The Choreography pattern is one of them.
13+
14+
The SAM template contains all the information to deploy AWS resources and also the permission required by these service to communicate.
15+
16+
You will be able to create and delete the CloudFormation stack using AWS SAM.
17+
18+
This is fully functional example implemented in Java 11.
19+
20+
Important: this application uses various AWS services and there are costs associated with these services after the Free Tier usage - please see the AWS Pricing page for details. You are responsible for any AWS costs incurred.
21+
22+
#### Language:
23+
#### This is a Maven project which uses Java 11 and AWS SDK
24+
25+
#### Framework
26+
The framework used to deploy the infrastructure is SAM
27+
28+
#### Services used
29+
30+
#### API Gateway - AWS Lambda - DynamoDB
31+
32+
#### Deployment commands
33+
34+
````
35+
mvn clean package
36+
37+
aws s3 mb s3://hifo8q34hfksdjnfpqwf
38+
39+
aws s3 cp target/sourceCode.zip s3://hifo8q34hfksdjnfpqwf
40+
41+
sam deploy --s3-bucket hifo8q34hfksdjnfpqwf --stack-name choreography-pattern --capabilities CAPABILITY_IAM
42+
````
43+
44+
Add cinemas and movies in DynamoDB tables
45+
````
46+
aws dynamodb batch-write-item --request-items file://./dynamodb/movies.json
47+
48+
aws dynamodb batch-write-item --request-items file://./dynamodb/cinemas.json
49+
````
50+
51+
#### TESTING
52+
53+
Copy the URL from the SAM Outputs:
54+
CloudFormation outputs from deployed stack
55+
56+
Key PaymentsEndpoint
57+
Description API Gateway Cinema Endpoint
58+
Value https://XXXXXXXX.execute-api.XXXXXXXXXX.amazonaws.com/prod/cinema
59+
60+
Add the cinemaID/movies at the end of the URL. cinemaID available: aaaa and bbbb
61+
62+
````
63+
curl https://XXXXXXXX.execute-api.XXXXXXXX.amazonaws.com/prod/cinema/aaaa/movies -H "Accept: application/json"
64+
65+
curl https://XXXXXXXX.execute-api.XXXXXXXX.amazonaws.com/prod/cinema/bbbb/movies -H "Accept: application/json"
66+
````
67+
68+
#### CLEAN-UP
69+
70+
71+
````
72+
aws cloudformation delete-stack --stack-name choreography-pattern
73+
74+
aws s3 rm s3://hifo8q34hfksdjnfpqwf --recursive
75+
76+
aws s3 rb s3://hifo8q34hfksdjnfpqwf
77+
````
78+
#### Requirements
79+
80+
* [Create an AWS account](https://portal.aws.amazon.com/gp/aws/developer/registration/index.html) if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
81+
* [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html) installed and configured
82+
* [AWS Serverless Application Model](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html) (AWS SAM) installed
