Published a special episode of AWS Bites, getting ready for AWS re:Invent 2021! 😱

13. What’s on your re:Invent 2021 wish list?


https://www.youtube.com/watch?v=NY03iwbOkzk

In this special episode, Eoin and Luciano talk about their wishlist for AWS re:invent 2021. Based on our experience and personal AWS pain points, we share some of our wishes for new announcements during the biggest cloud event of the year. We also discuss some of the biggest announcements of last year and a few tips on how to get ready to follow the announcements of the next few days.

⚠️ CORRECTION on Data Transfer cost: The changes in data transfer were not reported accurately in this episode. The monthly data transfer free tier limit has changed from 1 GB/month per region to 100GB/month for all regions. Data transfer out of CloudFront is now free for 1TB/month, up from 50GB/month.

11. How do you move away from the management console?


In this episode, Luciano and Eoin discuss the good and the bad of the AWS Management Console (a.k.a. the web console) and why you should consider migrating to Infrastructure as Code (IaC) as soon as possible, especially for your production applications.

In this episode we mentioned the following resources:
- Cloudformation: https://aws.amazon.com/cloudformation/
- CDK: https://aws.amazon.com/cdk/
- Serverless Framework: https://www.serverless.com/
- SAM: https://aws.amazon.com/serverless/sam
- Terraform: https://www.terraform.io/
- Former2: https://former2.com/
- Import or create (e.g. if the resource already exists in production). With CDK: https://loige.co/create-resources-con...

AWS Observability made simple


Have you ever thought that your Lambda functions could fail without you even noticing?

If the answer is YES, that’s probably because you already “burnt" yourself playing with the cloud, where errors and failures are always around the corner…

Unfortunately we can’t prevent all types of failures, but what we can do is try to spot them as soon as possible and react quickly.

In order to do that, we need good observability for our serverless applications and therefore we need to become good friends with services like CloudWatch.

If you have tried CloudWatch already, you probably know how powerful but also complex it can be…

In this talk we will approach the topic of observability for serverless applications on AWS. We will discuss best practices and how to build a good friendship with CloudWatch.

We will also present some interesting automation tools that we can use to take away most of the pain of setting up dashboards and alarms in CloudWatch, making it easier to achieve great levels of observability.
