Network operator project planning

When planning a Corda deployment as a Business Network Operator, there are several considerations:

  • Deployment environments
  • Notary compatibility
  • HSM compatibility
  • Database compatibility
  • Corda Enterprise Network Manager deployment

When deploying a private network, the Business Network Operator is responsible for all major components of the Corda network. In most enterprise deployments of Corda this includes:

  • Nodes
  • An HA notary cluster
  • An HA Corda Firewall
  • An HSM
  • The certificate hierarchy of the network

The Business Network Operator also deploys Corda Enterprise Network Manager in a private network. This deployment includes an identity manager and a network map.

When deploying a public network, the Network Operator is responsible for all major components of the Corda network.

Deployment environments

Business Network Operators will need several deployments of Corda Enterprise, at least including:

  • A development environment including minimal network infrastructure.
  • A testing environment including a basic network, without HA notary, Corda Firewall, or HSMs.
  • A UAT environment, that includes the full network infrastructure, with a shared HSM, and HA Corda Firewall.
  • The production environment, including an HA notary cluster, HA Corda Firewalls on all nodes, HSMs, and network services.

Node sizing and databases

When defining the requirements of a node, it is important to define the resources that the node will require. While every Corda deployment will have different requirements - depending on the CorDapps and business model of the parties - the following table gives approximate sizings for typical node deployments.

Size JVM Heap # Cores Minimum Host RAM
Small 1GB 1 2GB to 3GB
Medium 4GB 8 8GB
Large 32GB 32 64GB
X-Large > 32GB > 32 > 64GB

All Corda Nodes have a database. A range of third-party databases are supported by Corda, shown in the following table:

Vendor CPU Architecture Versions JDBC Driver
Microsoft x86-64 Azure SQL,SQL Server 2017 Microsoft JDBC Driver 6.4
Oracle x86-64 11gR2 Oracle JDBC 6
Oracle x86-64 12cR2 Oracle JDBC 8
PostgreSQL x86-64 9.6, 10.10 11.5 PostgreSQL JDBC Driver 42.1.4 / 42.2.8
