An overview of Serverless services on AWS

    Due to constant digitalization many companies try to make a mark and opt for serverless applications and services.
    The pain points serverless services help to solve:
  • Scalability
  • Costs spent on in-house data centers & servers
  • Expenses on IT specialists to support & maintain in-house servers
    Learn about the most popular AWS serverless services grouped according to their functions. Serverless services will make your application secure, scalable, reliable, and available globally.

As the world steadily shifts to complete digitalization, we can see more and more serverless applications on the market. Having a serverless application means that you do not have to invest in an in-house server infrastructure, host a whole team of server managers, or worry about scalability. AWS hosts a unique ecosystem of services that allow you to have your app’s server infrastructure completely in the cloud.

In this article, I would like to provide you with an overview of AWS’s serverless services by categorising them according to their basic functionality.

1. Computing

Amazon Lambda

AWS Lambda

AWS Lambda is a pay-per-use computing environment that takes care of server and operating system maintenance for you, as well as scales automatically according to your application’s needs. If you choose to use AWS Lambda as your app’s computing environment, you will only be responsible for the code you provide, leaving all the infrastructure management headache behind. Lambda is a great service that is suitable in many development scenarios for any kind of application.

SNS messages can be distributed via mobile push notifications, e-mail, SMS, Amazon SQS, Amazon Lambda, or to an HTTP endpoint. Amazon SNS has no upfront costs and employs a pay-per-use model, is highly reliable, and uses server-side encryption to deliver your messages in the most secure way.
