Tips for Success

Here are a few tips for success as you work on these DIY projects:

  • Start small and simple. Don’t try to build a complex application right away. Start with a simple project, such as the serverless image resizer or the serverless contact form.
  • Break down the project into smaller tasks. Once you have a good understanding of the overall project, break it down into smaller, more manageable tasks. This will make the project seem less daunting and help you stay on track.
  • Use existing resources. There are many resources available to help you learn AWS Lambda and serverless computing. Don’t be afraid to use them.
  • Don’t be afraid to experiment. The best way to learn is by doing. Don’t be afraid to experiment with different approaches and solutions.
  • Have fun! Learning AWS Lambda and serverless computing should be enjoyable. If you’re not having fun, you’re less likely to stick with it.


Congratulations, you’ve embarked on a journey to master AWS Lambda through hands-on projects. By completing these DIY projects, you’ll not only gain practical experience but also have a portfolio of serverless applications that demonstrate your skills to potential employers or clients.

Remember that the best way to learn is by doing. Dive into these projects, experiment, and adapt them to your unique needs. As you tackle real-world serverless challenges, you’ll become a Lambda expert, ready to take on any serverless project that comes your way.

So, roll up your sleeves, fire up your AWS console, and let’s start building with Lambda. Your serverless journey begins now!
