Editing Graph Database (section)

== Neo4J ==

Neo4J would be suitable for what we're trying to achieve. The community edition is most likely suffice for our dataset and things like relationships,contact tracing etc.

=== For a Small Dataset (2GB) ===
# '''EC2 with EBS'''
#* '''Best For''': Simple and low-cost setup.
#* '''Estimated Cost''': ~$9/month.
# '''ECS with EFS'''
#* '''Best For''': Flexibility (though it might be overkill unless scaling significantly).
#* '''Estimated Cost''': ~$16/month.
# '''Neo4j Aura Free Tier'''
#* '''Best For''': Simplicity and no upfront cost (if workload fits within free limits).

=== For a 5GB Dataset ===
# '''EC2 with EBS'''
#* '''Best For''': Simple, cost-efficient setup with moderate scaling needs.
#* '''Configuration''': 
#** Instance: t3.medium (2 vCPUs, 4GB RAM) recommended for moderate query loads.
#** Storage: 20GB EBS gp3 (to allow room for growth and logs).
#* '''Estimated Cost''': ~$40/month (EC2: ~$38, EBS: ~$2).
# '''ECS with EFS'''
#* '''Best For''': Flexibility, especially if you’re familiar with containerized environments.
#* '''Configuration''': 
#** 1 ECS Fargate task (1 vCPU, 2GB RAM) with 10GB EFS.
#* '''Estimated Cost''': ~$25/month (ECS: ~$22, EFS: ~$3).
# '''Neo4j Aura Professional'''
#* '''Best For''': Workloads exceeding free tier limits (200K nodes/400K relationships).
#* '''Estimated Cost''': ~$65/month.

=== For a 10GB Dataset ===
# '''EC2 with EBS'''
#* '''Best For''': Cost efficiency with predictable workloads.
#* '''Configuration''': 
#** Instance: t3.medium (2 vCPUs, 4GB RAM) or m5.large (2 vCPUs, 8GB RAM) for heavy workloads.
#** Storage: 30GB EBS gp3 for dataset and transaction logs.
#* '''Estimated Cost''': ~$41/month (EC2: ~$38, EBS: ~$3).
# '''ECS with EFS'''
#* '''Best For''': Scalability and AWS integration.
#* '''Configuration''': 
#** 1 ECS Fargate task (2 vCPUs, 4GB RAM) with 20GB EFS.
#* '''Estimated Cost''': ~$35/month (ECS: ~$30, EFS: ~$5).
# '''Neo4j Aura Professional'''
#* '''Best For''': Handling datasets larger than the free tier but requires a subscription.
#* '''Estimated Cost''': ~$65/month.
