Well-architected Infrastructure

The Five Pillars of well-architected Infrastructure:

Operational Excellence
- How support development and run workloads effectively ?

Security
- How to secure infrastructure, application and data ?

Reliability
- How to perform application intended function correctly and consistently when it’s expected to ?

Performance
- How to use computing resources efficiently to meet system requirements ?

Cost
- How to run systems to deliver business value at the lowest price point?

Reliability

Reliability - The probability that a system will produce correct outputs at a given time.

Serviceability - Simplicity and speed with which a system can be repaired or maintained.

Availability - The probability that a system is operational at a given time.

NOTE: The accepted availability standard for emergency response systems is 99.999% or “five nines” – or about five minutes and 15 seconds of downtime per year.

Observability

Aggregate below 3 sources to make discoveries and predictions about the functioning of a complex system, which would otherwise be difficult:

Logs - Generated by most systems components and applications and consist of time-series data about the functioning of the system or application.
Traces - Track the flow of logic within the application.
Metrics - CPU/RAM reservation or usage, disk space, network connectivity, and more.
