Dopo una breve introduzione dei concetti di base legati all'Internet of Things, durante questa sessione si fornirà una panoramica degli strumenti che Microsoft mette a diposizione degli sviluppatori per creare le proprie soluzioni IoT: Windows 10 for IoT e alcuni servizi di Azure quali Event Hubs e Stream Analytics. Si utilizzerà un semplice esempio di telemetria per mostrare la realizzazione pratica di uno scenario end-to-end per la trasformazione dei dati provenienti da un sensore in informazioni utili per effettuare analisi e/o prendere decisioni.

- Per il 2020 la connettività dei dispositivi diventerà uno STD, anche grazie alla riduzione dei costi delle componenti. Si potranno usare componenti dal costo inferiore a 1 dollaro da applicare agli oggetti per farli comunicare con internet e altri oggetti. Avremo anche nuovi modelli di business: se si pensa alle assicurazioni, si può pensare a un monitoraggio di cert parametri sulla base dei quali è possibile calcolare la quota da pagare (usage-based insurance) Ci saranno poi tecnologie sensor-specific (ad esempio nel manufacturing) e tecnologie diffuse (smart buildings)
- Key goal of slide: One of the key goals of data insight is to get predictive. Through the central collection and processing of data, machine learning and algorithms can be applied to the data set to analyze the historical data and arrive at reasonable accuracy levels for future events. This predictive approach can be applied in a number of ways, from simple notification, to alert and notification depending in the situation.

- Key goal of slide: As we look at a deeper layer of detail for a scenario, it could look like this. The producers are potentially like the 4 listed here. Apps, older devices, IP connected or smaller devices. These may connect directly to Event Hubs in Azure, or they may hop through either Field or Cloud gateways where translation is performed. As this diagram illustrates, the destination in Azure, Event Hubs, enables the data to take a route of 1 of 2 choices. Either the data can be processed by tools like Stream Analytics, Storm or something custom, or it can be formatted for delivery to a specified storage location. If Storage is the destination, there are a number of options, or even combinations that can be utilized. DB, Table, Blob, HDI or even back to a Service Bus could be engaged as a return loop for command and control scenarios. Finally, the data travels through this infrastructure and may be presented in any number of ways
- infine è necessario visualizzare i dati che sono stati elaborati in modo tale da poter effettuare delle valutazioni utili per il proprio business. I servizi Azure che permettono la visualizzazione sono molteplici: App Service: in particolare con Web App e Mobile App servizi come il Notification Hub permettono di inviare una notifica nel caso in cui ci sia un valore per cui si debba prestare una particolare attenzione all’interno del flusso oppure altri strumenti più complessi che MS mette a disposizione come il CRM Dynamics, che possono essere utilizzati per la presentazione dei dati in realtà enterprise
- riassunto di tutti i servizi che possono essere applicati in una soluzione IOT end-to-end molti di questi li abbiamo già affrontati mi vorrei soffermare sui servizi di storage che non abbiamo visto finora questi permettono di gestire l’archiviazione dei dati che sono letti dai device
- Inserire una foto con tutti gli HW (+Band se riusciamo a metterlo)
- Stream Analytics mi serve per fare un analisi del flusso dei dati in tempo reale. Non analizza il dato singolo, ma il flusso, senza perdere le caratteristiche. Ecco perchè usarlo per la telemetria Un’applicazione tipica per l’analisi dei flussi ha una struttura come questa. I principali component sono: Input – sorgenti degli eventi. Le sorgenti “proprie” di uno scenario di questo tipo sono device, macchine, applicazioni, sensori, etc. In ogni caso, ASA non è direttamente connesso a questi. La prima interfaccia con I dati che provengono da queste sorgenti è EH. ASA è ottimizzato per prendere il flusso di dati da EH e dagli Azure Blob. Azure Blob Storage is the likely place where log data is stored. The list of input sources that ASA directly integrates with may increase in the future, but Azure Event Hubs and Azure Blob Storage will be the primary sources. Query – componente principale di ASA. Le query implementano la logica di analisi. Sono un set di trasformazioni che vengono applicate al flusso in inut per produrre un flusso di output. Le query sono l’unico element che gli sviluppatori di ASA devono effettivamente sviluppare/scrivere. Tutto il resto viene completamente gestito attraverso il portale di gestione di Azure. Una cosa molto importante da notare è che ASA supporta un linguaggio simile al SQL per le query, ma a differenza di un DB tradizionale queste query sono eseguite continuamente sullo streaming dei dati. Si fermano solo nel caso in cui vengano fermate manualmente o vanno in pausa nel momento in cui non ci sono dati da processare Output – Quando una query viene eseguita, questa produce dati continuamente. Questi risultati possono essere memorizzati in Blob Storage, EH o in SQL Database su Azure. L’input processato e memorizzato in uno di questi servizi può essere riutilizzato come input di un nuovo processo. È quindi possibile concatenare tra loro diversi processi per effettuare una serie di trasformazioni sui dati che provengono dall’esterno. Posso avere 2 input in stream analytics: il flusso corrente e un flusso che avevo memorizzato prima ad esempio in un blob storage. Stream Analytics può fare un’analisi continua del flusso sttuale rispetto a quello storico.
- Tumbling windows specify a repeating, non-overlapping time interval of a fixed size. Syntax: TUMBLINGWINDOW(timeunit, windowsize) Timeunit – day, hour, minute, second, millisecond, microsecond, nanosecond. Windowsize – a bigInteger that described the size (width) of a window. Note that because tumbling windows are non-overlapping each event can only belong to one tumbling window. The query just counts the numbers of vehicles passing the toll station every 20 seconds, grouped by Toll Id.
