Network ConfigurationsΒΆ
CfnCluster leverages Amazon Virtual Private Cloud(VPC) for networking. This provides a very flexiable and configurable networking platform to deploy clusters within. CfnCluster support the following high-level configurations:
- Single subnet, master and compute in the same subnet
- Two subnets, master in one subnet and compute new private subnet
- Two subnets, master in one subnet and compute in exisiting private subnet
All of these configurations can operate with or without public IP addressing. It can also be deployed to leverage an HTTP proxy for all AWS requests. The combinations of these configurations result in many different deployment scenario’s, ranging from a single public subnet with all access over the Internet, to fully private via AWS Direct Connect and HTTP proxy for all traffic.
Below are some architeture diagrams for some of those scenarios:
The configuration for this architecture, requires the following settings:
note that all values are examples only
[vpc public]
vpc_id = vpc-a1b2c3d4
master_subnet_id = subnet-a1b2c3d4
The configuration for this architecture, requires the following settings:
note that all values are examples only
[vpc public-private]
vpc_id = vpc-a1b2c3d4
master_subnet_id = subnet-a1b2c3d4
compute_subnet_cidr = 10.0.1.0/24
