All modules are provisioned considering resilience mechanisms such as:

* Multiple availability zones.
* Self-healing systems.
* Load balancing.
* Auto scaling.

The diagram below represents the architecture with multiple availability zones. 
The same concept is applied to any product module. 
This includes database, cache, messaging, etc.

The macro process is:

<Steps>
<Step>
The request arrives at one of the load balancer entry points. 
Note that the entry points work in **active-active** mode.
</Step>
<Step>
The load balancer forwards the request to an available integration.
</Step>
<Step>
Integration goes out to the internet through *NAT gateways*.
</Step>
<Step>
Request reaches the *backend* (optionally using a VPN).
</Step>
<Step>
Throughout the process there is redundancy between zones, as resources from one zone can be consumed by another in **active-active** mode.
