Streamlining Operations with Azure Functions in Serverless Environments

This content examines the transformative impact of Azure Functions on operational efficiency within serverless computing contexts. This powerful cloud service simplifies application management, automates processes, and reduces operational overhead, making it an essential tool for modern businesses looking to enhance their cloud strategies.

Key Benefits of Using Azure Functions to Streamline Operations:

Automated Scalability: Azure Functions automatically scales based on the demand by adjusting the number of computing resources in real-time. This capability ensures that applications perform optimally under any load, eliminating the need for manual scaling and reducing resource wastage.

Reduced Operational Complexity: By abstracting the underlying infrastructure management, Azure Functions allows developers to focus purely on writing and deploying code. This serverless approach minimizes the tasks associated with server maintenance, updates, and configuration, thereby streamlining operations.

Event-driven Automation: Azure Functions excels in environments that require responsive, event-driven solutions. It can trigger processes in response to various events, such as changes in data, updates from IoT devices, or new information from APIs, automating workflows and reducing the latency in data processing.

Integration and Connectivity: With extensive support for integrating with other Azure services and external applications, Azure Functions facilitates the creation of interconnected systems that can effortlessly communicate and exchange data. This integration is pivotal for creating seamless workflows and enhancing data flow across applications.

Cost Efficiency: Operating on a pay-as-you-go model, Azure Functions ensures that costs are directly aligned with usage, with no upfront costs or fees for idle capacity. This pricing model is particularly advantageous for businesses with fluctuating workloads, as it allows for precise budget management based on actual usage.

Azure Functions is revolutionizing how businesses approach cloud computing in serverless environments, offering a suite of tools that not only streamline operations but also foster innovation and agility. By leveraging Azure Functions, organizations can achieve higher operational efficiency, faster time to market, and greater scalability—all while maintaining control over costs and resource utilization.

Origen web para evitar gateway PowerBi y Azure Functions

Existen diversos escenarios donde PowerBi nos va a exigir un gateway para actualizar nuestra información. A veces es muy necesario y tiene sentido, pero otras veces no y resulta hasta molesto.

Puede que haya muchos escenarios más que los que voy a mencionar pero normalmente al escrapear un sitio web (funcion Web.Pages de power query) se exige un gateway. Tal vez tenes alguna operación tan compleja que se te ocurre usar Python para resolverla porque esta dentro de Power Bi, pero con eso también te exige Gateway.

Este artículo mostrará como podemos usar Azure Functions para realizar una operación simple con Python para luego leerlo desde PowerBi como un simple Get Request de API.

Primero que nada un poco de teoría. Existen escenarios web los cuales requeiren de Gateway para su tratamiento. Aun si estamos en power query online (dataflows) necesitaremos uno. Hay tres funciones cláscias que son de interés y funcionan distinto. WebContent, WebPages y WebContentBrowser. Si quieren conocer la diferencia y entender cual pide gateway y cual no, pueden leer la siguiente doc: https://learn.microsoft.com/en-us/power-query/connectors/web/web-troubleshoot

Me gustaría comenzar aclarando que no voy a hacer una introducción a Azure Functions. No voy a explicar que es, cómo funciona y cómo setear el entorno. Para eso ya hay excelentes videos en internet o podemos leer más en la siguiente doc de microsoft:

https://learn.microsoft.com/es-es/azure/azure-functions/create-first-function-vs-code-python?pivots=python-mode-configuration

Para este post necesitamos conocimientos previos en Python básico y Visual Studio Code. Asumiendo que ya tenemos el entorno seteado con las extensiones de Visual Studio code, vamos a comenzar con un ejemplo sencillo conectando a una API. Ya logueados en el apartado de Azure y con visibilidad a nuestra suscripción, vamos a crear una Function App. Podemos pensarlo como el servidor de procesamiento de muchas Azure Functions. En ese espacio podemos tener muchas functions, pensemos a cada una como un request.

Al momento de crearla tenemos 4 pasos

Ese nombre será participe de la URL de la API que estamos generando. 

Ahora podremos crear la función. Se almacenará en la carpeta que tengamos apuntando el Visual Studio Code. Clickeamos el rayito para crear una función dentro de la Function App

La aplicación creada se verá así:

Lo que necesitamos saber es que tenemos una función main donde se ejecutará el código principal. Luego depende si llamamos a la función con get o post si podemos capturar items de parametros de url o body. Eso nos ayudaría a incrementar la seguridad puesto que sin los parametros correctos o autenticación no podríamos obtener la respuesta. A modo de ejemplo vamos a hacer una simple lógica para que la url retorne el resultado cada vez que sea llamada sin necesidad de nada más puesto que considero que no es sensible la data del nombre de los workspaces en mi tenant de demo.

Veamos que simple es escribir código dentro de main devolviendo un dict o json en el return bajo el status_code deseado. Podemos aprovecharnos de los mensajes para ser claros en fallas para recibirlas en Power Bi. 

Código de la imagen en mi Github.

Usando SimplePBI para obtener grupos, pueden ver que simplemente generamos token, creamos objeto de grupo (workspaces) y llamamos a los workspaces que nuestro Service Principal puede ver.

Luego agregue al return una aclaración adicional para cuando lo que queremos devolver no es un “texto” literal sino un dict o json que es el “mimetype”.

NOTA: Si no sabes que es SimplePBI podes pasar por aqui.

IMPORTANTE: aclaro que tenemos un secret expuesto en este código, lo mejor para una azure function así sería usar un Azure KeyVault a nuestras contraseñas y secretos para que no queden expuestos.

Si vamos a usar una librería importada tendremos que buscar el archivo requirements.txt en el panel de recursos y agregarla. Yo lo hice para SimplePBI.

Si necesitamos utilizar pandas para tomar datos de un origen estructurado, podemos utilizar “ DataFrame.to_dict(orient="records") ” en el json.dumps del return para convertir nuestro frame al formato de mimetype json.

Get data

Mucho sobre python y funciones, vamos a PowerBi Desktop a conectarnos. Usaremos el conector web para traer la información con credenciales anónimas.

Dependiendo como orientamos nuestro json devuelto en la API que nos generamos en Azure Functions vamos a tener que efectuar transformaciones en power query. En este caso la devuelta por SimplePBI es muy uniforme y el motor practicamente lo resuelve solo.

Veamos como queda:

Ahora tenemos nuestra data cargada en Power Bi usando python sin necesidad de un gateway personal. Ya podemos publicar nuestro informe al servicio de power bi y configurar las credenciales como anónimas.

ACLARACIÓN: las Azure Functions tiene un límte de uso (timeout) en 5 minutos. Nuestra ejecución no puede durar más de eso o fallaría y nuestro propósito quedaría perdido.

Conclusión

Esta metodología puede ayudarnos a dar más velocidad a pequeños desarrollos, scrappings u origenes cloud complicados que PowerBi no tenga connector sin driver (ejemplo: oracle o mysql). Con una Azure Function construir rápido y fácilmente una API que responda. Para aumentar la seguridad es necesario utilizar Azure KeyVaults en nuestro código y en caso de necesitar disponibilizar data más sensible, lo mejor sería pedir un parámetro o body con alguna clase de key (que puede ser inventada por nosotros) para que no todo quede sobre una URL pública. Espero que este ejemplo les despierte nuevas ideas.

i love it when the academic articles i'm reading about include swearing (the one i'm reading is actually *about* swearing) but come on. do you want me to be able to read the word fuck in this thing and expect me not to laugh a little about it?

ZESTIRIA THOUGHT BEFORE I FORGET: every attack has a Notable windup and cooldown and ESPECIALLY every hidden arte has these and i like that you can tell they went "okay. so we accidentally installed a Fun Ceiling" about that when they were niceing the combat system for berseria.

they made a whole thing out of banish blasts taking like 3 of god's own seconds to happen after you commit to them & it was mature of them to notice that this sucked (even tho having it happen instantly on a stunned enemy rocked) (not really worth it)

Oooh, more than that, and I want to blab about it!

So in short CrowdStrike, a Cybersecurity company, more or less accidentally cyber attacked Microsoft's Cloud Services via a bugged update. Microsoft uses CrowdStrike's services for their Cloud Services, and missed the bug as well one way or another (in what I hope was an isolated check they did before uploading the updated version to their customers that happened to not have caught the fatal error.)

The update fatally corrupted Microsoft's Cloud System to such a degree that any of their customers using their Cloud Systems in their software were rendered useless.

What the lovely Dean doesn't say here is a lot of these Customers systems are whole POS systems. Aside from diners, every POS systems I've encountered since yesterday has been down and rendered useless: hotels, arcades, some general stores. Mostly it seems like bigger Customers/Companies (bigger companies are using Microsoft's Cloud Services).

Also if anyone is up for PMing me any outages they're experiencing that I don't have listed please lmk! I'm curious and would love to list.

So far I know:

Several Airlines

Several Banks

Several State's 911 lines

Several POS Systems (likely the VM issue)

Several Hospitals

TBC

(research/looking around. I don't have my computer cuz I'm stuck at an airport, but I might go through and see if I can find customer lists and get specific and otherwise update this.)

Here is a link to the Microsoft Cloud/Azure Outage report:

(This is the status history; it is the first ticket 1K80-N_8)

Here is a link to the VM (Virtual Machine) Microsoft Cloud/Azure outage that is currently still active:

(Since it is still active, it is listed on the front page)
