About gRPC

gRPC is a modern open source high performance RPC framework that can run in any environment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication. It is also applicable in last mile of distributed computing to connect devices, mobile applications and browsers to backend services.

PRINCIPLES OF CHAOS ENGINEERING

CHAOS IN PRACTICE

To specifically address the uncertainty of distributed systems at scale, Chaos Engineering can be thought of as the facilitation of experiments to uncover systemic weaknesses.  These experiments follow four steps:
  1. Start by defining ‘steady state’ as some measurable output of a system that indicates normal behavior.
  2. Hypothesize that this steady state will continue in both the control group and the experimental group.
  3. Introduce variables that reflect real world events like servers that crash, hard drives that malfunction, network connections that are severed, etc.
  4. Try to disprove the hypothesis by looking for a difference in steady state between the control group and the experimental group.
The harder it is to disrupt the steady state, the more confidence we have in the behavior of the system.  If a weakness is uncovered, we now have a target for improvement before that behavior manifests in the system at large.

AWS Well-Architected Framework

https://d0.awsstatic.com/whitepapers/architecture/AWS_Well-Architected_Framework.pdf


Abstract 

This paper describes the AWS Well-Architected Framework, which enables customers to review and improve their cloud-based architectures and better understand the business impact of their design decisions. We address general design principles as well as specific best practices and guidance in five conceptual areas that we define as the pillars of the Well-Architected Framework.
