Andreas Wittig and Michael Wittig focusing on AWS Cloud
We are two brothers focusing 100% on Amazon Web Services (AWS). Every other week, one of us prepares the topic of the podcast. The topic is not known to the other one, which results in surprising conversations about all things AWS.
Typically, we are covering the following topics: DevOps, Serverless, Container, Security, Infrastructure as Code, Container, Continuous Deployment, S3, EC2, RDS, VPC, IAM, VPC, and many more.

Don't miss the our blog post Review: AWS App Mesh – A service mesh for EC2, ECS, and EKS, the written version of this podcast episode.
Building a service mesh is trending those days. App Mesh provides service mesh capabilities for EC2, ECS, and EKS. For free! On top of that, App Mesh integrates with a bunch of AWS services like Cloud Map, Certificate Manager, CloudWatch, and X-Ray. App Mesh is a new service still at the very beginning. Our service maturity score of 4.7 indicates that it is too early to use App Mesh right now. Let’s wait for AWS to improve the service step by step based on other AWS customers’ feedback.
The fundamental problem is that App Mesh is not a fully managed service. As an App Mesh customer, you need to deploy and operate 1-3 sidecar containers per task (aka. pod). This contradicts the goal of having the cloud provider take over as many tasks as possible.
It is frustrating that activating CloudWatch metrics incurs costs of more than $150 per month for a mesh consisting of two services. Also, $400 per month for a private CA provided by ACM will probably be a show stopper for most scenarios.
Overall, App Mesh is only for service mesh enthusiasts.

Notes
How do you choose the best storage option on AWS?
Choosing storage service is critical when designing a cloud architecture. Read on to learn about the characteristics, limitations, typical use cases, and a decision tree for the following options to store data on AWS:
Instance Store provides low latency and high throughput block storage for EC2 instances.
EBS (Elastic Block Storage) provides persistent block storage for EC2 instances.
EFS (Elastic File System) provides a scalable and fault-tolerant network file system (NFSv4).
FSx (File System for Windows File Server) provides a fully-managed Windows File Server.
S3 (Simple Storage Service) provides highly scalable and fault-tolerant object storage.
This podcast episode is based on the blog post Storage on AWS, which was published first on the Cloudcraft blog.

#21 Review: API Gateway HTTP APIs
Cheaper and Faster REST APIs?

Notes
Don't miss our blog post Review: API Gateway HTTP APIs - Cheaper and Faster REST APIs?, the written version of this podcast episode.
HTTP APIs
An API gateway acts as an API front-end that receives API requests from clients and forwards them to back-end services. Typically, an API gateway offers the following features:
Throttling
Billing
Authentication and authorization
Request validation
Request and response transformation
AWS offers different types of API gateways as a managed service. This review takes a closer look at the new service API Gateway HTTP APIs announced in December 2019 and generally since available in March 2020. The cloud provider promises that HTTP APIs are faster and cheaper than it's predecessor. We will look at hard technical facts instead of flowery marketing promises.
A summary of Amazon's API gateways to avoid confusion:
API Gateway REST APIs is the full-feature flagship service to build REST APIs announced in 2015.
API Gateway HTTP APIs is the fast and straightforward alternative to build REST APIs announced in 2019.
API Gateway WebSocket APIs was announced in 2018 and allows you to build a real-time API using WebSockets.
Application Load Balancer (ALB) is a layer-7 load balancer with similarities with an API gateway.
This review focuses on HTTP APIs.
