A deployment architecture is a mapping of the system architecture to a physical environment. This environment consists of machines that run code, load balancers, databases, network elements, and so on. The mapping of a logical architecture and software artifacts to a deployment involves the following:

• Defining what infrastructure components are needed
• Defining the environments needed
• Sizing analysis for each environment: Estimating the number and characteristics of the resources needed for an efficient environment
• Management strategies: A pipeline that defines how new code gets deployed in an environment

This section discusses the typical components, configurations, and environments of production systems.
