I am new to server background. I am using AWS server to my project.I just want make chat api for android and ios. What is step by step to make chat api in aws?
If you want to go with a Server approach then you can use the following product on Amazon EC2 to create a Popular XMPP server (ejabbered)

Nowadays going serverless is getting more common and would like you to look on this example with AWS Lambda
Example : AWS Lambda Chat

I'm trying to make a ChatBot that uses Dialog Flow and should be able to pickup Keywords and match it to the Intents.
I've worked with Microsoft Bot Framework using Luis and deployed a similar bot on Azure but now I have to do the exact same thing but have to deploy that on AWS and use Elastic Search.
How do I do that? Is there a similar Software available for AWS ?
you can use AWS lex for create chatbot,here is the link for aws lex
https://docs.aws.amazon.com/lex/latest/dg/getting-started.html.
for performing back-end task like validation and dynamic response from bot side,then you need to use lambda again lambda also AWS tool that provide to how to make server-less bot.

hope this kt will help you.
I have an existing mobile app that can receive push notifications and I have an existing backend application that exposes an API for sending notifications to the app. The backend application uses Firebase Cloud Messaging (FCM), so it could be considered a wrapper around FCM. My backend application uses the Firebase Admin SDK to create messages and send them to Firebase. My customers hit an API exposed by my backend application (so, if we assume that the customer is using Postman, then the flow for sending a message is: Postman->My backend application->Firebase->Mobile app).
Until now I have been running my backend application on a local server, and it works fine. But now I need to deploy this on AWS. My question is: is it necessary to use Amazon SNS or not? I don't really need any additional functionality from AWS, I just want AWS to permit the required communication.
For example, I dont need to go to an AWS interface to enter the token to send messages to my phone. I already have an API exposed through my backend for sending messages. So, should I even bother to set up SNS?
I know that at a minimum I will have to make my firebase project google credentials available to my instance on AWS (in a file located at the path specified using GOOGLE_APPLICATION_CREDENTIALS). What other configuration steps would be needed? Thanks a lot.
After some investigation I found that it is not necessary to use Amazon SNS to achieve what I wanted to achieve.
I was able to deploy my server application (which uses Firebase Cloud Message) to AWS, and the messages arrive on the mobile phones without any problem.
I initialized my backend application using the steps described on the Google Firebase site: https://firebase.google.com/docs/admin/setup
I like the friendly interface that AWS Mobile Hub provides to disparate Amazon services, but I'd like to use it to create a web application, rather than a native iOS or Android app.
It's not clear to me how to do so, since there's no option for javascript sample code or any mention of web applications:
Am I missing something? Is there documentation for this use-case elsewhere?
All of the resources that are configured by various features in Mobile Hub (e.g., NoSQL Database, Cloud Logic APIs) are usable directly from a web app in the browser. For example, you can turn on the App Content Delivery feature, enable web hosting on your Amazon S3 bucket, download/copy the AWS JavaScript SDK into your Amazon S3 bucket, and start writing your web app. The JavaScript SDK will allow you to interact with your Mobile Hub resources (found on the "Resources" page in the left Nav menu in Mobile Hub's console).
However, we do realize these steps are tedious and we have had similar feedback from other customers. So, we are actively working to make these steps easier.
In the meantime, you can get the AWS JavaScript SDK here:
https://aws.amazon.com/sdk-for-browser/
And, you may find some of our github samples are a good starting point, like this one:
https://github.com/awslabs/lambda-refarch-webapp
For those looking to build web apps, AWS has a JavaScript library called AWS Amplify that makes building cloud web apps easy: https://aws.github.io/aws-amplify/
I would like to add Amazon services to my CodeName one App, I have downloaded java-SDK from Amazon and added a library to my App. Everything working properly in simulator once I gave Android build.
If I try to access Amazon AWS in my android app I'm getting an error like "NoClassDefFoundError".
Here my question is CodeName one supports Amazon AWS or not.
If Codename One supports integration with Amazon AWS then how can I integrate and use below AWS services
Amazon Cognito,
Amazon Cognito Sync,
Amazon API Gateway,
Amazon DynamoDB,
AWS Device Farm,
Amazon SNS(Simple Notification Service),
Amazon Analytics.
You can't just add an arbitrary JAR to Codename One, because we don't support all the features of Java SE as explained here.
There are two ways in which you can support Amazon and you can see samples of both approaches in the libraries section of Codename One.
Wrap the native Android/iOS libraries - there is a long tutorial for this here and in the developer guide.
Wrap the webservice/JSON API's which is a better approach in many regards as it is 100% portable and will bring you into platforms like UWP, Desktop, Web etc. This is the approach taken by parse4cn1.
Option 2 is superior for solutions like AWS as it's much easier to debug and doesn't require any native code etc. Ideally we'd love to have a proper AWS cn1lib similarly to the parse cn1lib.
I'm trying to create push notifications for my mobile application.
Is it possible integrate Delphi FireMonkey with Amazon SNS services?
Thanks.
(Using Delphi 10 Seattle)
The Amazon APIs are REST based. You can simply use the INDY component library or maybe even the Rest Client that shipped recently with Delphi. Also, Delphi has built in classes for talking to many of the AMAZON services like S3. You can use those as an example.
Amazon Integrator from n/software makes it easy to access Amazon Web Services from Delphi
Easy-to-use components can be used to add, modify and delete objects stored on S3 or SimpleDB, add or remove messages from SQS, integrate with ASW e-commerce services, or control EC2 instances. As well as SNS

Short answer is Yes.
Its possible to use Amazon Cloud API with Delphi. Extending Cloud API, Amazon Simple Notification Service (SNS) let you send notifications using different protocols including email, http and push notifications. (TAmazonSNS Service)
There are 3 provided classes to access Amazon Web Services with Cloud API:
Simple Storage Service (S3)
Simple Database Service (SimpleDB)
Simple Queue Service (SQS)
