Amazon SQS + Delay By Connect Integrations

Amazon SQS?

Amazon Simple Queue Service (Amazon SQS. is a web service that provides a reliable, highly scalable hosted queue for storing messages as they travel between computers. It is a high-performance, distributed queuing service that lets you decouple the components of a cloud application. You can use Amazon SQS to receive messages from one application and route them to another application or process for further processing. The Amazon SQS message queue provides a critical communication channel between distributed applications and components of a cloud application. When one component of an application sends messages to the message queue, another component of the application can retrieve the messages and perform some work on those messages. This helps to decouple these components by allowing them to communicate via Amazon SQS instead of being tightly integrated.

Delay By Connect?

Delay By Connect allows you to delay your SNS notifications by connecting them to an SQS queue. You can delay the sending of notifications by up to 5 seconds, which is useful if you want to ensure that your messages don’t get sent out in an automated fashion. If you send out a bunch of notifications in rapid succession, it’s possible that your infrastructure will be saturated with requests and become overloaded. By delaying your messages for up to 5 seconds, you can ensure that your infrastructure stays stable and doesn’t experience any issues.

OK, now that you know what we’re going to talk about, let’s get started!

Integration of Amazon SQS and Delay By Connect

• One of the biggest value propositions of Amazon SQS is its ability to provide reliable messaging as a service. Messages are held in queues until they are retrieved by another process or component of an application. To integrate Amazon SQS into your application, you need to have some sort of client library available, which can be found here. This library will give you the ability to interact with your Amazon SQS queues directly through code.
• You also need the ability to connect your application to Amazon SQS, but this is easy because Amazon provides several SDKs that allow you to do it. For this tutorial, I’m going to be using Python because it gives you more flexibility than other languages like Java or C#. You can create an account on the AWS Management Conspe at https://conspe.aws.amazon.com/conspe/. From there, click on Services > SQS > Create New Queue:
• You should then see the fplowing window:
• Now you’re ready to create your new queue on Amazon SQS! Just click on Create New Queue and give it a name like “my_queue_name”:
• Once your queue has been created, you’ll see something like this:
• Now that you’ve created your queue on Amazon SQS, we need to add a rule so that we can send messages from our application into our newly created queue:
• Now you can select a rule type which will describe how you want your messages sent into the queue:
• Now we need to create a ppicy which specifies who can access our queue and what operations they can perform on it:
• Now we’re ready to set up the rules for the ppicy we just created:
• We can also set up an ACL for our queue now:
• Finally, we have to set up some limits for our queue:
• Now that we have all that set up, we need to create a bot that will run on Delay By Connect and wait for our message to get delivered in our Amazon SQS queue:
• To do this, we need to go back to our Amazon SQS and click on our new queue name again:
• Click on Get Messages and select what format you want your data returned in from the dropdown menu:
• Once you’ve selected your desired format, click on Show Messages:
• A list of all messages in your queue will appear underneath the “Show Messages” button:
• Click on Create Bot (the plus symbp. Then fill in all of the fields in the dialog box:
• Now click on Save Bot and then on View Key so that we can use this key later when we start sending messages from our application into Amazon SQS:
• We need to go back to our application now and send a message into our Amazon SQS queue via our bot:
• Once the message is received by Delay By Connect, it will push it over into Amazon SQS after the specified delay time has passed! And just like that, we have successfully integrated Delay By Connect and Amazon SQS!
