46. How do you do machine learning on AWS?

The public cloud gives you amazing machine learning powers with a low barrier to entry. Once you know where to begin, you can quickly build solutions to process images, video, text and audio, as well as structured data. In this episode we talk about the managed AI services that are available on AWS and that require zero machine learning expertise (Rekognition, Polly, Transcribe, Forecast, Personalise, Comprehend, Lex, Textract, Translate). We will also talk about services you can use to create a...

45. What’s the magic of OIDC identity providers?

If you are thinking of using an external CICD tool to deploy to AWS you are probably wondering how to securely connect your pipelines to your AWS account. You could create a user for your CICD tool of choice and copy some hard coded credentials into it, but, let’s face it: this doesn’t feel like the right - or at least the most secure - approach! In the previous episode we discussed how AWS and GitHub solved this problem by using OIDC identity providers and this seems to be a good solution to th...

44. Do you use CodePipeline or GitHub Actions?

Automated, Continuous Build and Continuous Delivery are must-haves when building modern applications on AWS. To achieve this, you have numerous options, including third party providers like GitHub Actions and Circle CI, and the AWS services, CodePipeline and CodeBuild. In this episode we focus on GitHub Actions and we compare it with the native AWS features offered by services like CodePipeline and Code Build. In particular we discuss what CodePipeline offers and how to set it up, what the trade...

43. When is it OK to cheat on AWS?

We do love AWS, but sometimes we have to admit that it’s not always a silver bullet. There are definitely use cases where it might be worth considering alternatives to AWS. In this episode we will discuss some of these use cases and try to highlight what are the advantages that other platforms or services can have over AWS in very specific circumstances. First of all we clarify why we like AWS and why (and when) it’s worth sticking with it. Then, we discuss what are some of the reasons why it mi...

42. How do you containerise and run your API with Fargate?

We recently talked about migrating a monolithic application to AWS, using EC2, load balancers, S3 and RDS. In this episode we want to talk about a slightly different setup, where we are going for containers instead of EC2 and we want to deploy them in Fargate. In this We are going to cover all the components you will need in your architecture, the reasons to choose Fargate over any alternatives and discuss some CDK tricks to get started in a quick way (and the pitfalls that might come with them)...

41. How can Middy make writing Lambda functions easier?

Lambda functions are small units of code that achieve a specific purpose. It’s always a good idea to keep your code short, clean and simple. And yet, sometimes you find yourself writing lots of boilerplate code in every function to do common things, like parsing events, validation, loading parameters and lots more. The Middy.js framework was designed to help you keep Node.js Lambda function code simple, letting you focus on the business logic and clearing away duplication and boilerplate. By the...

40. What do you need to know about IAM?

Identity Access Management, also known as IAM, can be an intimidating service when getting started with AWS. But IAM is also one of those core services that you can’t really avoid. In this episode we try to distill down everything that you need to know to understand IAM and start to use it proficiently. We cover what IAM is, why it is so important, how authentication and authorization work, what policy documents are and how to write them, how a user or an application get credentials to interact ...

39. How do you build a cross-account event backbone with EventBridge?

When it comes to building and deploying microservice applications on AWS, there are 2 emerging best practices: use a separate AWS account per application (and environment) and decouple communication between separate systems using events (instead of point-to-point communication). Can we use these two best practices together? Yes, but we will need to find a way to pass messages between AWS accounts! In this episode we discuss how to do that using EventBridge as a cross-account event backbone! We d...
