It’s important to note that charting a context map can be a challenging task. When a system’s bounded contexts encompass multiple subdomains, there can be multiple integration patterns at play. For example, in Figure 4-9, you can see two bounded contexts with two integration patterns: partnership and anticorruption layer.

Moreover, even if bounded contexts are limited to a single subdomain, there still can be multiple integration patterns at play—for example, if the subdomains’ modules require different integration strategies.
