ColdFusion with AWS AppSync: GraphQL API Management for Modern Applications

[govindhtech]

AWS AppSync API Allows Namespace Data Source Connectors

Amazon AppSync API

Amazon AppSync Events now supports channel namespace data source connections, enabling developers to construct more complicated real-time apps. This new functionality links channel namespace handlers to AWS Lambda functions, DynamoDB tables, Aurora databases, and other data sources. AWS AppSync Events allows complex, real-time programs with data validation, event transformation, and persistent event storage.

Developers may now utilise AppSync_JS batch tools to store events in DynamoDB or use Lambda functions to create complicated event processing processes. Integration enables complex interaction processes and reduces operational overhead and development time. Without integration code, events may now be automatically saved in a database.

Start with data source integrations.

Use AWS Management Console to connect data sources. I'll choose my Event API (or create one) in the console after browsing to AWS AppSync.

Direct DynamoDB event data persistence

Data sources can be integrated in several ways. The initial sample data source will be a DynamoDB table. DynamoDB needs a new table, thus create event-messages in the console. It just needs to build the table using the Partition Key id. It may choose Create table and accept default options before returning to AppSync in the console.

Return to the Event API setup in AppSync, choose Data Sources from the tabbed navigation panel, and click Create data source.

After identifying my data source, select Amazon DynamoDB from the drop-down. This shows DynamoDB configuration options.

After setting my data source, it may apply handler logic. A DynamoDB-persisted publish handler is shown here:

Use the Namespaces tabbed menu to add the handler code to a new default namespace. Clicking the default namespace's setup information brings up the Event handler creation option.

Clicking Create event handlers opens a dialogue window for Amazon. Set Code and DynamoDB data sources to publish.

Save the handler to test console tool integration. It wrote two events to DynamoDB using default parameters.

Error handling and security

The new data source connectors provide sophisticated error handling. You can return particular error messages for synchronous operations to Amazon CloudWatch to protect clients from viewing sensitive backend data. Lambda functions can offer specific validation logic for channel or message type access in authorisation circumstances.

Now available

AWS AppSync Events now provide data source integrations in all AWS regions. You may use these new features via the AWS AppSync GUI, CLI, or SDKs. Data source connectors only cost you for Lambda invocations, DynamoDB operations, and AppSync Events.

Amazon AppSync Events

Real-time events

Create compelling user experiences You may easily publish and subscribe to real-time data updates and events like live sports scores and statistics, group chat messages, price and inventory level changes, and location and schedule updates without setting up and maintaining WebSockets infrastructure.

Public/sub channels

Simplified Pub/sub

Developers can use AppSync Event APIs by naming them and defining their default authorisation mode and channel namespace(s). All done. After that, they can publish events to runtime-specified channels immediately.

Manage events

Edit and filter messages

Event handlers, which are optional, allow developers to run complex authorisation logic on publish or subscribe connection requests and change broadcast events.

AWS Amplify Features For Building Scalable Full-Stack Apps

AWS Amplify features

Build

Summary

Create an app backend using Amplify Studio or Amplify CLI, then connect your app to your backend using Amplify libraries and UI elements.

Verification

With a fully-managed user directory and pre-built sign-up, sign-in, forgot password, and multi-factor auth workflows, you can create smooth onboarding processes. Additionally, Amplify offers fine-grained access management for web and mobile applications and enables login with social providers like Facebook, Google Sign-In, or Login With Amazon. Amazon Cognito is used.

Data Storage

Make use of an on-device persistent storage engine that is multi-platform (iOS, Android, React Native, and Web) and driven by GraphQL to automatically synchronize data between desktop, web, and mobile apps and the cloud. Working with distributed, cross-user data is as easy as working with local-only data thanks to DataStore’s programming style, which leverages shared and distributed data without requiring extra code for offline and online scenarios. Utilizing AWS AppSync.

Analysis

Recognize how your iOS, Android, or online consumers behave. Create unique user traits and in-app analytics, or utilize auto tracking to monitor user sessions and web page data. To increase customer uptake, engagement, and retention, gain access to a real-time data stream, analyze it for customer insights, and develop data-driven marketing plans. Amazon Kinesis and Amazon Pinpoint are the driving forces.

API

To access, modify, and aggregate data from one or more data sources, including Amazon DynamoDB, Amazon Aurora Serverless, and your own custom data sources with AWS Lambda, send secure HTTP queries to GraphQL and REST APIs. Building scalable apps that need local data access for offline situations, real-time updates, and data synchronization with configurable conflict resolution when devices are back online is made simple with Amplify. powered by Amazon API Gateway and AWS AppSync.

Functions

Using the @function directive in the Amplify CLI, you can add a Lambda function to your project that you can use as a datasource in your GraphQL API or in conjunction with a REST API. Using the CLI, you can modify the Lambda execution role policies for your function to gain access to additional resources created and managed by the CLI. You may develop, test, and deploy Lambda functions using the Amplify CLI in a variety of runtimes. After choosing a runtime, you can choose a function template for the runtime to aid in bootstrapping your Lambda function.

GEO

In just a few minutes, incorporate location-aware functionalities like maps and location search into your JavaScript online application. In addition to updating the Amplify Command Line Interface (CLI) tool with support for establishing all necessary cloud location services, Amplify Geo comes with pre-integrated map user interface (UI) components that are based on the well-known MapLibre open-source library. For greater flexibility and sophisticated visualization possibilities, you can select from a variety of community-developed MapLibre plugins or alter embedded maps to fit the theme of your app. Amazon Location Service is the driving force.

Interactions

With only one line of code, create conversational bots that are both interactive and captivating using the same deep learning capabilities that underpin Amazon Alexa. When it comes to duties like automated customer chat support, product information and recommendations, or simplifying routine job chores, chatbots can be used to create fantastic user experiences. Amazon Lex is the engine.

Forecasts

Add AI/ML features to your app to make it better. Use cases such as text translation, speech creation from text, entity recognition in images, text interpretation, and text transcription are all simply accomplished. Amplify makes it easier to orchestrate complex use cases, such as leveraging GraphQL directives to chain numerous AI/ML activities and uploading photos for automatic training. powered by Amazon Sagemaker and other Amazon Machine Learning services.

PubSub

Transmit messages between your app’s backend and instances to create dynamic, real-time experiences. Connectivity to cloud-based message-oriented middleware is made possible by Amplify. Generic MQTT Over WebSocket Providers and AWS IoT services provide the power.

Push alerts

Increase consumer interaction by utilizing analytics and marketing tools. Use consumer analytics to better categorize and target your clientele. You have the ability to customize your content and interact via a variety of channels, such as push alerts, emails, and texts. Pinpoint from Amazon powers this.

Keeping

User-generated content, including images and movies, can be safely stored on a device or in the cloud. A straightforward method for managing user material for your app in public, protected, or private storage buckets is offered by the AWS Amplify Storage module. Utilize cloud-scale storage to make the transition from prototype to production of your application simple. Amazon S3 is the power source.

Ship

Summary

Static web apps can be hosted using the Amplify GUI or CLI.

Amplify Hosting

Fullstack web apps may be deployed and hosted with AWS Amplify’s fully managed service, which includes integrated CI/CD workflows that speed up your application release cycle. A frontend developed with single page application frameworks like React, Angular, Vue, or Gatsby and a backend built with cloud resources like GraphQL or REST APIs, file and data storage, make up a fullstack serverless application. Changes to your frontend and backend are deployed in a single workflow with each code commit when you simply connect your application’s code repository in the Amplify console.

Manage and scale

Summary

To manage app users and content, use Amplify Studio.

Management of users

Authenticated users can be managed with Amplify Studio. Without going through verification procedures, create and modify users and groups, alter user properties, automatically verify signups, and more.

Management of content

Through Amplify Studio, developers may grant testers and content editors access to alter the app data. Admins can render rich text by saving material as markdown.

Override the resources that are created

Change the fine-grained backend resource settings and use CDK to override them. The heavy lifting is done for you by Amplify. Amplify, for instance, can be used to add additional Cognito resources to your backend with default settings. Use amplified override auth to override only the settings you desire.

Personalized AWS resources

In order to add custom AWS resources using CDK or CloudFormation, the Amplify CLI offers escape hatches. By using the “amplify add custom” command in your Amplify project, you can access additional Amplify-generated resources and obtain CDK or CloudFormation placeholders.

Get access to AWS resources

Infrastructure-as-Code, the foundation upon which Amplify is based, distributes resources inside your account. Use Amplify’s Function and Container support to incorporate business logic into your backend. Give your container access to an existing database or give functions access to an SNS topic so they can send an SMS.

Bring in AWS resources

With Amplify Studio, you can incorporate your current resources like your Amazon Cognito user pool and federated identities (identity pool) or storage resources like DynamoDB + S3 into an Amplify project. This will allow your storage (S3), API (GraphQL), and other resources to take advantage of your current authentication system.

Hooks for commands

Custom scripts can be executed using Command Hooks prior to, during, and following Amplify CLI actions (“amplify push,” “amplify api gql-compile,” and more). During deployment, customers can perform credential scans, initiate validation tests, and clear up build artifacts. This enables you to modify Amplify’s best-practice defaults to satisfy the operational and security requirements of your company.

Infrastructure-as-Code Export

Amplify may be integrated into your internal deployment systems or used in conjunction with your current DevOps processes and tools to enforce deployment policies. You may use CDK to export your Amplify project to your favorite toolchain by using Amplify’s export capability. The Amplify CLI build artifacts, such as CloudFormation templates, API resolver code, and client-side code generation, are exported using the “amplify export” command.

Tools

Amplify Libraries

Flutter >> JavaScript >> Swift >> Android >>

To create cloud-powered mobile and web applications, AWS Amplify provides use case-centric open source libraries. Powered by AWS services, Amplify libraries can be used with your current AWS backend or new backends made with Amplify Studio and the Amplify CLI.

Amplify UI components

An open-source UI toolkit called Amplify UI Components has cross-framework UI components that contain cloud-connected workflows. In addition to a style guide for your apps that seamlessly integrate with the cloud services you have configured, AWS Amplify offers drop-in user interface components for authentication, storage, and interactions.

The Amplify Studio

Managing app content and creating app backends are made simple with Amplify Studio. A visual interface for data modeling, authorization, authentication, and user and group management is offered by Amplify Studio. Amplify Studio produces automation templates as you develop backend resources, allowing for smooth integration with the Amplify CLI. This allows you to add more functionality to your app’s backend and establish multiple testing and team collaboration settings. You can give team members without an AWS account access to Amplify Studio so that both developers and non-developers can access the data they require to create and manage apps more effectively.

Amplify CLI toolchain

A toolset for configuring and maintaining your app’s backend from your local desktop is the Amplify Command Line Interface (CLI). Use the CLI’s interactive workflow and user-friendly use cases, such storage, API, and auth, to configure cloud capabilities. Locally test features and set up several environments. Customers can access all specified resources as infrastructure-as-code templates, which facilitates improved teamwork and simple integration with Amplify’s continuous integration and delivery process.

Amplify Hosting

Set up CI/CD on the front end and back end, host your front-end web application, build and delete backend environments, and utilize Amplify Studio to manage users and app content.

11 Dịch vụ AWS Serverless xịn nên sử dụng trong kiến trúc cloud

11 Dịch vụ AWS Serverless xịn nên sử dụng trong kiến trúc cloud

Serverless services là những dịch vụ thuộc dạng fully managed services có nghĩa là mọi thứ liên quan đến hạ tầng underlying hardware, provision, maintenance, patching, hay thậm chí cao hơn về bảo mật sử dụng cũng được AWS làm sẵn cho mình. Serverless có thể gọi là lý tưởng cho các developer thay vì nỗi lo về máy chủ cấp phát, cấp phát có thừa hay quá thiếu hay không, sau khi đưa vào sử dụng có cần phải update, upgrade patching gì không (Đây thực sự là ác mộng với các bạn developer mà ko rành về hạ tầng, về CLI, shell này nọ).

AWS hiểu được điều này và offer một số dạng dịch vụ gọi là serverless như thế.

Serverless là gì?

Serverless dịch Tiếng Việt là “Phi máy chủ” nhưng dịch ra có vẻ hơi ngớ ngẩn, mình cũng không biết dịch sao cho thoát nghĩa. Serverless không phải là không có máy chủ theo nghĩa đen, bản chất của serverless nằm lớp bên dưới vẫn là các máy chủ, nhưng AWS làm cho việc này một cách mờ đi (transparency hay invisibility) và tự động quản lý vận hành lớp hạ tầng này miễn sao cung cấp đủ capacity như thiết kế cho bạn.

AWS Serverless

Definition of serverless computing: Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of the their customers – Wikipedia

Serverless refers to applications where the management and allocation of servers and resources are completely managed by the cloud provider. – Serverless-Stack

Serverless is a cloud-native development model that allows developers to build and run applications without having to manage servers. There are still servers in serverless, but they are abstracted away from app development. – Redhat
