4. Monolith vs Microservice

5. Observability
“Observability is a measure of how well internal states of a
system can be inferred from knowledge of its external outputs”.

6. Pillars of Observability
1. Monitoring
2. Logging
3. Tracing

7. Monitoring
1. Prometheus
2. Graphite
3. InfluxDB

9. Logging
1. FluentD
2. FluentBit
3. Logstash

12. Tracing
● Jaeger
● Zipkin
● Kiali

13. Jaeger Architecture

14. Jaeger benefits
● Distributed transaction monitoring
● Performance & latency optimisation
● Root cause analysis
● Service dependency analysis
● Distributed context propagation

15. Jaeger features
● Uses consistent upfront sampling with individual per service/endpoint
probabilities
● Multiple storage backends: Cassandra, Elasticsearch, memory.
● Adaptive sampling
● Post-collection data processing pipeline
● Libraries available in Java, GO, Node, Python, C++

16. Terminology
● Span ⇒ A span represents a logical unit of work in Jaeger that has an operation
name, the start time of the operation, and the duration. Spans may be nested
and ordered to model causal relationships.
● Trace ⇒ A trace is a data/execution path through the system, and can be
thought of as a directed acyclic graph of spans.
