# AWS IoT SiteWise esempi che utilizzano SDK per Python (Boto3)
I seguenti esempi di codice mostrano come eseguire azioni e implementare scenari comuni utilizzando AWS SDK per Python (Boto3) with AWS IoT SiteWise.
*Nozioni di base*: esempi di codice che mostrano come eseguire le operazioni essenziali all’interno di un servizio.
Le *azioni* sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le azioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati.
Ogni esempio include un link al codice sorgente completo, in cui vengono fornite le istruzioni su come configurare ed eseguire il codice nel contesto.

AWS IoT SiteWise is a fully managed software-as-a-service (SaaS) that
makes it easy to collect, store, organize, and monitor data from industrial equipment and processes.
It is designed to help industrial and manufacturing organizations collect data from their equipment and
processes, and use that data to make informed decisions about their operations.
One of the key features of AWS IoT SiteWise is its ability to connect to a wide range of industrial
equipment and systems, including programmable logic controllers (PLCs), sensors, and other
industrial devices. It can collect data from these devices and organize it into a unified data model,
making it easier to analyze and gain insights from the data. AWS IoT SiteWise also provides tools for
visualizing the data, setting up alarms and alerts, and generating reports.
Another key feature of AWS IoT SiteWise is its ability to scale to handle large volumes of data.
It can collect and store data from thousands of devices and process millions of data points per second,
making it suitable for large-scale industrial operations. Additionally, AWS IoT SiteWise is designed
to be secure and compliant, with features like role-based access controls, data encryption,
and integration with other AWS services for additional security and compliance features.
