Observability is making the transition from being a niche concern to becoming a new frontier for user experience, systems, IoT and service management across all organizations. James will discuss what this means for the developers of modern applications and how to use observability to derive deep insights into system performance and user experience.

Reframing for
Observability

12. Do you test in
production?

13. Many concurrent connections
A specific network stack with specific tunables, firmware, and NICs
Iffy or nonexistent serializability within a connection
Race conditions
Services loosely coupled over networks
Network flakiness
Ephemeral runtimes
Specific CPUs and their bugs; multiprocessors
Specific hardware RAM and memory bugs
Specific distro, kernel, and OS versions
Specific library versions for all dependencies
Build environment
Deployment code and process
Runtime restarts
Cache hits or misses
Specific containers or VMs and their bugs
Specific schedulers and their quirks
Clients with their own specific back-offs, retries, and time-outs
The internet at large
Specific times of day, week, month, year, and decade
Noisy neighbors
Thundering herds
Queues
Human operators and debuggers
Environment settings

is a love letter

36. Progressive delivery is a modern software
development and devops practice for gradually
rolling out new features in order to limit the potential
negative impact and gauge user engagement with
new product features.

Experience

45. Observability enables product management experimentation, with managed
risk
Rapid iterations
Bringing growth hacking approaches to software delivery
Feature management is a bridge
Progressive Delivery, segmented user populations
Testing in production is a given
Improving collaboration between engineering, product management and
development
Observability is a set of conversations
between users and product owners
between product owners and engineers
between engineers and systems
between users and systems
IoT – a network of black boxes
Observability is a cultural change – in telemetry, logging, error messages,
