Azure Storage storage solution that supports all types of data, including: blobs, queues, and NoSQL. workflows Business processes modeled in software are often called Logic Apps Microsoft Power Automate WebJobs Azure Functions Azure includes four different technologies that you can use to build and implement workflows that integrate multiple systems run actions, accept inputs, include conditions, produce outputs, All workflow technologies design-first approach They both include user interfaces in which you can draw out the workflow Logic Apps a service within Azure that you can use to automate, orchestrate, and integrate disparate components of a distributed application connector is a Logic Apps component that provides an interface to an external service. Microsoft Power Automate is a service that you can use to create workflows even when you have no development or IT Pro experience. Automated, Button, Scheduled, Business Process, 4 types of workflow Automated Flow A flow that is started by a trigger from some event. Button flow runs a repetitive task with a single click from your mobile device. Scheduled flow A flow that executes on a regular basis such as once a week, on a specific date, or after 10 hours. Business process flow A flow that models a business process such as the stock ordering process or the complaints procedure. Continuous, Triggered, There are two kinds of WebJob WebJobs are a part of the Azure App Service that you can use to run a program or script automatically Azure Function is a simple way for you to run small pieces of code in the cloud, without having to worry about the infrastructure required to host that code. HTTPTrigger Use this template when you want the code to execute in response to a request sent through the HTTP protocol. TimerTrigger Use this template when you want the code to execute according to a schedule. BlobTrigger. Use this template when you want the code to execute when a new blob is added to an Azure Storage account. CosmosDBTrigger Use this template when you want the code to execute in response to new or updated documents in a NoSQL database. WebJobs, Functions, Code-first technologies Serverless compute as a function as a service (FaaS), or a microservice that is hosted on a cloud platform. Serverless compute a great option for hosting business logic code in the cloud. Durable Functions that allows you to orchestrate the executions of multiple functions without any timeout. function app Functions are hosted in an execution context called a Consumption service plan. This is the plan that you choose when using the Azure serverless application platform. It provides automatic scaling and bills you when your functions are running. Azure App Service plan This plan allows you to avoid timeout periods by having your function run continuously on a VM that you define. you are responsible for managing the app resources the function runs on. Bindings are a declarative way to connect data and services to your function. Trigger is a special type of input binding that has the additional capability of initiating execution Timer trigger Execute a function at a set interval. HTTP trigger Execute a function when an HTTP request is received. Blob trigger Execute a function when a file is uploaded or updated in Azure Blob storage. Queue trigger Execute a function when a message is added to an Azure Storage queue. Azure Cosmos DB trigger Execute a function when a document changes in a collection. Event Hub trigger Execute a function when an event hub receives a new event. timer trigger is a trigger that executes a function at a consistent interval. Timestamp parameter name which is simply an identifier to access the trigger in code. Schedule which is a CRON expression that sets the interval for the timer CRON expression a string that consists of six fields that represent a set of times. first field represents seconds. This field supports the values 0-59. Because the field contains a zero, it selects the first possible value, which is one second. second field represents minutes. The value "/5" contains two special characters. First, the asterisk () means "select every value within the field." Because this field represents minutes, the possible values are 0-59. The second special character is the slash (/), which represents an increment. When you combine these characters together, it means for all values 0-59, select every fifth value. An easier way to say that is simply "every five minutes." last four fields represent the hour, day, month, and weekday of the week. An asterisk for these fields means to select every possible value. In this example, we select "every hour of every day of every month." _rid The resource ID is a unique identifier that is also hierarchical per the resource stack on the resource model. It is used internally for placement and navigation of the item resource. _self The unique addressable URI for the resource. _etag Required for optimistic concurrency control. _attachments The addressable path for the attachments resource. _ts The time stamp of the last update of this resource. Partition key specifies how the documents in Azure Cosmos DB collections are distributed across logical data partitions. Blob Storage You can use the blob output binding to write blobs. Azure Cosmos DB The Azure Cosmos DB output binding lets you write a new document to an Azure Cosmos DB database using the SQL API. Event Hubs Use the Event Hubs output binding to write events to an event stream. You must have send permission to an event hub to write events to it. HTTP Use the HTTP output binding to respond to the HTTP request sender. This binding requires an HTTP trigger and allows you to customize the response associated with the trigger's request. This can also be used to connect to web hooks. Microsoft Graph Microsoft Graph output bindings allow you to write to files in OneDrive, modify Excel data, and send email through Outlook. Mobile Apps The Mobile Apps output binding writes a new record to a Mobile Apps table. Notification Hubs You can send push notifications with Notification Hubs output bindings. Queue Storage output binding to write messages to a queue. Send Grid Send emails using bindings. Service Bus output binding to send queue or topic messages. Table storage Use an Azure Table storage output binding to write to a table in an Azure Storage account. Twilio Send text messages One How many triggers must a function have? 2. What is the name of the file that contains function configuration data? Durable Functions enables you to implement complex stateful functions in a serverless-environment. orchestration function describe how actions are executed, and the order in which they are run. You write the logic in code (C# or JavaScript). Client, Orchestrator, Activity, three durable function types Activity functions are the basic units of work in a durable function orchestration. This function contains the actual work performed by the tasks being orchestrated. Client functions are the entry point for creating an instance of a Durable Functions orchestration. They can run in response to an event from many sources, such as a new HTTP request arriving, a message being posted to a message queue, an event arriving in an event stream. You can write them in any of the supported languages. Fan out/fan in This pattern runs multiple functions in parallel and then waits for all the functions to finish. The results of the parallel executions can be aggregated or used to compute a final result. Function chaining In this pattern, the workflow executes a sequence of functions in a specified order. The output of one function is applied to the input of the next function in the sequence. The output of the final function is used to generate a result. Async HTTP APIs This pattern addresses the problem of coordinating state of long-running operations with external clients. An HTTP call can trigger the long-running action. Then, it can redirect the client to a status endpoint. The client can learn when the operation is finished by polling this endpoint. Monitor This pattern implements a recurring process in a workflow, possibly looking for a change in state. For example, you could use this pattern to poll until specific conditions are met.
