That is this group? How does it work? What is the CNCF? After this short introduction I am going to show you what is Opentracing what it means and why the adoption is growing so much in a short amount of time. Use cases, possible implementations and so on.

2. Cloud Native Computing Foundation
• Non-profit, part of the Linux Foundation
– Founded December 2015
• Current projects:
• Platinum members:
Kubernetes Prometheus OpenTracing Fluentd Linkerd gRPC CoreDNS containerd rkt CNI

3. Today the Linux Foundation is much more than Linux
We are helping
global privacy
and security
through a
program to
encrypt the
entire internet.
Security Networking
We are creating
ecosystems around
networking to
improve agility in the
evolving
software-defined
datacenter.
Cloud
We are creating a
portability layer for
the cloud, driving de
facto standards and
developing the
orchestration layer
for all clouds.
Automotive
We are creating the
platform for
infotainment in the
auto industry that
can be expanded
into instrument
clusters and
telematics systems.
Blockchain
We are creating a
permanent, secure
distributed ledger
that makes it easier
to create
cost-efficient,
decentralized
business networks.
We are regularly adding projects; for the most up-to-date listing of all projects visit tlfprojects.org

Web
We are providing the
application
development
framework for next
generation web,
mobile, serverless,
and IoT applications.

4. Containers
Cloud
Native
Cloud Native: CNCF (Founded 2015)
•Cloud native computing uses an open source
software stack to:
– segment applications into microservices,
– packaging each part into its own container
– and dynamically orchestrating those
containers to optimize resource utilization

Value Propositions

6. Container packaged applications achieve dev/prod parity,
foster code and component reuse and simplify operations
6
Isolation

7. No Lock-in
Open source software stack enables deployment
on any public or private cloud (or in combinations)
7

8. Unlimited Scalability
Optimized for modern distributed systems environments
capable of scaling to tens of thousands of self healing
multi-tenant nodes
(e.g., Google starts 2 billion containers per week)
8

9. Agility and Maintainability
Are increased by splitting applications into
microservices with explicitly described dependencies
9

10. Improved Efficiency and Resource Utilization
Via a central orchestrating process that dynamically
manages and schedules microservices. This reduces the
costs associated with maintenance and operations.
10

11. Resiliency
To failures of individual containers, machines, and
even data centers and to varying levels of demand

Typical problems with logs
¨ Which library do I need to use?
¨ Every library has a different format
¨ Every languages exposes a different format

17. © 2017 InfluxData. All rights reserved.17
Tracing is not something new
¨ There are vendors
¨ Every vendor has their own format

18. © 2017 InfluxData. All rights reserved.18
Every ten years, history repeats itself but now
¨ Microservices
¨ Polyglot architecture
¨ A different distribution

19. How do you “tell stories” about
concurrent systems?

20. Where does tracing code live?
OSS and commercial / in-house
instrumentation
Tracer SDKs /
clients
Tracing
backends and
UIs

Child Span
¨ Spans - Basic unit of timing and causality. Can be tagged with
key/value pairs.
¨ Logs - Structured data recorded on a span.
¨ Span Context - serializable format for linking spans across network
boundaries. Carries baggage, such as a request and client IDs.
¨ Tracers - Anything that plugs into the OpenTracing API to record
information.
¨ ZipKin, Jaeger, LightStep, others
¨ Also metrics (Prometheus) and logging

¨ Microservices
¨ Cache vs. Cache Miss
¨ Parallel vs Sequentially
¨ Queue system

PS I don’t know if it’s using OpenTracing (probably not) but it’s a nice visualisation.
