I have a requirement to forward the MQTT messages from HiveMQ broker to AWS SQS. Is it something that is feasible and can easily be done through HiveMQ Extension SDK?

I am quite new to MQTT implementations. I am managing to connect popular cloud based MQTT Brokers such thingsboard.io, Azure and AWS to send Sensor information to create dashboards for monitoring devices.
Problem
I have installed a local things-board broker to my local computer. But it is unable to reach other dashboards on the internet. Is it possible? Or is it only accessible within the local network?
It seems your doubt is more related to network connections. An MQTT broker will work in the same way, regardless it is working locally, in a fog server or in a cloud server. Obviously you will have to deal with access means: your clients/devices/applications must access the MQTT broker no matter where it is running. If you are running a local MQTT broker and it does not communicate directly with some cloud server, you can develop a specie of "gateway" only to send these data to the cloud or search for some tool that performs this task for you.
Below, you have some references regarding the working of MQTT and how to use it:

I have a site using html, php, javascript and css in which I add my data from IOT devices using MQTT broker. Now I want to update it and I want to connect my MQTT broker with Thingsboard MQTT to manage the same data from both platforms. How can I succeed the communication between the two MQTT brokers?
You have to use the "Thingsboard IoT Gateway". In the Gateway you can set your external MQTT Broker and connect it over the Gateway to Thingsboard. I think thats the only solution. Just follow the instructions.
I have an external broker us Apache Active MQ-MQTT.
I have a cumulocity IoT platform on the cloud.
I don’t understand how I can connect and subscribe my cumulocity application to broker MQTT.
There is no built in feature that would enable you to connect Cumulocity to an external MQTT broker. You could however create your own microservice that does this for you.
It seems that ThingsBoard implements its own MQTT broker and connector with Netty. We are trying to use an independent MQTT broker, how do we make ThingsBoard connect to that broker with minimum effort?
You should use ThingsBoard IoT Gateway project. It allows to connect to external MQTT broker and acts as an API bridge between your broker and ThingsBoard. For example, you can subscribe to custom topics and extract telemetry values or attribute updates from it. Similar with ThingsBoard RPC calls. Browse the following docs for an example of integration with AWS IoT:

I have installed mosquitto as a local broker. There are multiple devices which sends messages to the broker. I want that whatever message coming to mosquitto broker should be sent to azure IOT hub. Can anyone please refer to any document how to do that.
You have several approaches:
You can use one of the device client SDKs (depending on which
language you are using on your broker) to send data to IoT Hub
You
can use MQTT directly to communicate with IoT Hub, which will require
that you do specific things described in this document
(definitively recommend using the client SDK)
