Sending SMS Messages with Amazon SNS, AWS Lambda and Python

Did you know that you can send SMS messages easily with Amazon SNS without subscribing any phone numbers to a topic? Let’s say that you have verified phone numbers and you would like to send text messages to them assuming that they opted in for this. Besides, you would like to pay only when you send. You can use Amazon SNS SDK for Python and automate this process using AWS Lambda.

Triggering AWS Step Functions by AWS API Gateway Calls

If you recall, in a previous blog post I discussed AWS Step Functions as a great service for orchestrating your AWS Lambda functions by giving an example. Today, I will show you how you can integrate your API Gateway resource methods with your AWS Step Functions state machines so that you can trigger your state machines with API calls.

Actually the benefits are obvious. Instead of serving our Lambda functions as separate endpoints and orchestrating which one to call and when in our front end; we can use a single endpoint and pass all logic to the back end. Then our back end, in this case our state machine, will execute the functions in sequential or parallel. This method especially suits well to cases when all these function calls are necessary to complete a single business action.

Increasing Email Deliverability When Using Amazon SES

Increasing Email Deliverability When Using Amazon SES

Amazon Simple Email Service (SES) is one of the first AWS services I started using. It allows you to send automated emails without maintaining your email servers. It is scalable, easy to use with AWS SDKs and cost-effective.

However, you need to do more than verifying your domain on Amazon SES for your emails not to end in your users’ spam folder. In this blog post, I will discuss how you can increase the deliverability of your emails by setting DKIM and SPF authentications on Amazon SES.

An Introduction to Amazon Cognito User Pools

When you build a new application, developing a secure, scalable user pool and authorization mechanism is a necessity. It takes time and effort, and sometimes, it even delays the development of the core features that will bring actual value to your business.

Amazon Cognito provides a scalable and secure user pool for your mobile and web applications. It provides a hosted user interface and SDKs for sign-in and sign-up actions. It has many features, such as sending verification emails and SMS messages to your users. In this blog post, I will discuss how you can create an Amazon Cognito User Pool to use as an authentication mechanism in your applications.

Orchestrating AWS Lambda Functions Using AWS Step Functions

Orchestrating AWS Lambda functions with AWS Step Functions

While our serverless applications grow day by day; the need to orchestrate our Lambda functions may become an issue. We might need to execute some functions sequentially and one of our functions might get output of another function as input. Similarly, some functions might require to be executed in parallel. In these cases, AWS Step Functions can help us to coordinate our Lambda executions as components of our distributed applications and microservices.

In this blog post, I will make an introduction to AWS Step functions with a simple case. I will try to show how we can define sequential and parallel executions, as well as intermediary states to transform one state’s output to pass another state as input.
