AWS Basics — and points that stood out

I recently took a course on Linked In Learning on Amazon Web Services for developers since I knew that one day I might be using it eventually when I plan on deploying the applications I build on the cloud.

Most of the concepts I learnt were similar to cloud computing concepts that I had previously learnt, but some key points here stood out more than others.

Do take note that these key points are more specific to AWS services and have been categorised according to concepts.

Key Points (categorised according to concepts covered) :

1. AWS Essential SetUp :

  • You will be charged for using AWS for the first time but some services offer free usage under free tier, so do your research before you buy.

2. On Premise to AWS :

  • An availability zone can contain several individual data centers.

3. IaaS Computing :

  • Vertical scaling increases physical hardware to a single server.

4. IaaS Storage :

  • Serving web content with cloud front is a valid use case for public S3 bucket.

5. IaaS Networking :

  • If you want to use Route53, you only need to point your domain’s DNS servers to the Route53 servers.

6. Database as a Service (DBaaS) :

  • If 10,000 Internet of Things devices are sending in real-time telemetry on a certain situation at , let’s say 5/10-second intervals, the best service to capture this data would be Kinesis.

7. Platform as a Service (PaaS) :

  • Step Functions are the best service for implementing multi-step workflow within AWS.

8. Software as a Service (SaaS) :

  • Never put sensitive data on an S3 Bucket.

9. DevOps with AWS :

  • DevOps allows you to view your infrastructure as code.

10. Security on AWS :

  • CloudTrail tool can be enabled to maintain an audit log of access and changes to your AWS infrastructure to comply with some of the auditioning requirements of some compliance standards.

However, when it comes to the security of AWS, it is also worth noting that in February 2020, AWS was targeted by the largest DDoS Attack to date with a peak traffic volume of an astounding 2.3 Tbps using Connectionless Lightweight Directory Access Protocol (CLDAP) Reflection technique which uses CLDAP servers to amplify the data traffic by nearly 70 times. This was reportedly mitigated by AWS Shield.
