9 - Atoms, Molecules and the Cloud

Dell Boomi provides a cloud-based integration platform. It supports two deployment models: an in-the-cloud deployment model that is used when all the integration endpoints are cloud-based and an on-premise deployment model that is used when any of the integration endpoints are within a corporate network.

• If you are using the in-the-cloud model you can deploy your integration processes to the Dell Boomi Atom Cloud.
• To support the on-premise model, Dell Boomi provides a capability called an Atom, which is a lightweight Java virtual machine that is deployed on a host with Internet access.
• If you are using the on-premise model and want to have a highly available, load balanced solution; or if you are not happy with your Atom's processing time or volume handling; or if you are worried that your Atom's Processes may not run because of a computer outage, you should consider using a Molecule.
• In some cases you may need to share your Molecule across multiple customer accounts. If this is the case you should consider setting up your own Atom Cloud.

Comparison of the Features Available in Atoms, Molecules and Atom Clouds

Atoms, Molecules and Atom Clouds use the same basic technology but there are important differences between them. A Molecule is an Atom with multiple nodes. An Atom Cloud is a Molecule that is available to multiple tenants. The following table shows the features available in each.

Features	Atom	Molecule	Atom Cloud
Multi-tenancy, which means it can be used by multiple accounts
Disk space monitoring
Forked execution		*disabled by default
Multiple nodes, which provide load balancing and failover support
Supports integrations that will generate and/or receive a high volume of data
Available to customers
