Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.
Mitigating the Impact of State Management in Cloud Stream Processing SystemsScyllaDB
Stream processing is a crucial component of modern data infrastructure, but constructing an efficient and scalable stream processing system can be challenging. Decoupling compute and storage architecture has emerged as an effective solution to these challenges, but it can introduce high latency issues, especially when dealing with complex continuous queries that necessitate managing extra-large internal states.
In this talk, we focus on addressing the high latency issues associated with S3 storage in stream processing systems that employ a decoupled compute and storage architecture. We delve into the root causes of latency in this context and explore various techniques to minimize the impact of S3 latency on stream processing performance. Our proposed approach is to implement a tiered storage mechanism that leverages a blend of high-performance and low-cost storage tiers to reduce data movement between the compute and storage layers while maintaining efficient processing.
Throughout the talk, we will present experimental results that demonstrate the effectiveness of our approach in mitigating the impact of S3 latency on stream processing. By the end of the talk, attendees will have gained insights into how to optimize their stream processing systems for reduced latency and improved cost-efficiency.

then you would be better off updating your
applications
40. Anti-Pattern #3
“Big Brother”
The ESB is hosted, managed and controlled by
a central IT team
Because of organizational issues using the ESB
is complex:
e.g.
It takes months of meetings to get access
The Central IT team is trying to recoup the investment and
internally charges $000/year to use the ESB
The central IT deployment model holds up users
Departments and divisions actually sneak
behind the ESB
Set up peer-to-peer communications
Avoid the ESB at all costs
41. The biggest Anti-Pattern of all
Use an ESB because:
You heard it was a good idea
The salesman told you that you need one (over a
nice dinner)
You need a new TLA on your resume/CV
Its an excuse to spend several months learning
and going to conferences
43. The Concentrator Pattern
Mashup/Web Application
Dashboard
Concentrator ESB
Consistent access, security, logging, audit, monitoring
But no transformation
.NET CRM Apache
C/C++ Data
service service Axis2
service service
service
45. Provides a single entry point and allows
centralization of security enforcement for
incoming and outgoing messages.
Helps to apply transport-level and message-
level security mechanisms required for securely
communicating with a Web services endpoint.

52. USE-Case-3 (Business Scenario)
ABC company got several development groups that use various
Time tracking applications developed on SOA to track the effort
putting for the tasks.
Accounts department needs various reports from these different
Systems as a single view.
Some reports go through a validation process through some
sub-systems and the management wants to monitor the process.
57. Mashup Characteristics
● Situational application, consuming Web APIs
● Characteristics
● Lightweight
● Customized
● Aggregates data / Composes services
● Often combines personal and public data
● Recursive?
61. Importance of Mashups in a
SOA
● Helps bridge users to your SOA
● Emails
● IM
● Feeds
● Create mock services
● Helps create a prototypes quickly
● Improves Agility
63. What is a business process?
• A process you need to run your business!
• Any well-defined interaction between
systems and people, triggered by events,
using logical decision points, and with
clearly defined flows
64. Why business process matter?
• Enterprise applications and information
systems have became fundamental assets
• Enterprise information systems can
improve the efficiency of businesses
through automation of business processes
• To stay competitive applications must
quickly and efficiently adept to changing
business needs
65. Business Process Management
•Defining, Executing, and Monitoring
Business Processes Typically long-running,
stateful processes
Model
Innovate BPM Execute
Monitor
66. How does BPM fit with SOA
•Business Process Management needs to
connect to ‘operations’
–When processing an order, connect to the billing
system and raise an invoice
–When handling a problem ticket, connect to the
ticket management system
–Etc
•These operations could be direct
connection in-memory, but much more
likely to be distributed
•A service oriented architecture provides
the best way to connect the BPM to the SOA
67. BPM and SOA
BPM
Long running coordination state
SOA
Stateless service interactions
Applications, Databases, Legacy
Persistent application state
68. How does BPM work?
•Model
–Create a visual map of your process
•Refine
–Convert that visual map into an executable
process
•Execute
–Run that process
•Monitor
–Use built-in capabilities of the BPM platform to
monitor the state of processes
69. Executable business processes
•There are many approaches to executable
business processes:
–XPDL
–BPML
–YAWL
–jBPM
–WS-BPEL 1.1
BPEL 2.0
The industry standard
70. WS-BPEL
• Orchestration language used to describe
execution logic of Web services
applications by defining their control flows
and providing a way for partner services
to share a common context
• With WS-BPEL, you build a business
process by integrating a collection of Web
services into a business process flow
71. Understanding the relationship
between BPMN and BPEL
•BPMN is like UML
–Useful, especially as a higher level modeling
approach
–Allows formal modeling of processes by a
business analyst
–BPMN diagrams cannot be executed
•BPMN 2.0 is looking to define a better path to execution
•BPEL is like Java
–Can be directly executed
–Can be visualized using a graphical editor
–Can be created using BPMN as a guide
(refinement)
–
73. Monitoring Processes
•A key benefit of BPM
•Can range from:
–Simple stats on processes
–Inspect individual instances
–View overall flows across a process map
–Building custom business reports on specific
measures
•E.g. Sales / hour over the last week
74. USE-Case-4 (Business Scenario)
SOA development team needs to keep the metadata in a central
Place, manage them version them and get ready for the changes.
Same time looking to limit access to specific metadata sets.
79. Implementation
Identify the SOA architecture
Identify the governance team
Pick a framework, product
Iterative process
Data entry, configuration, (approach)
Dry run
Live run
Govern your SOA infrastructure
80. USE-Case-5 (Business Scenario)
A C/C++ Development team wants to implement SOA application, they
Will be reusing some existing Java and .Net backend services.
They are more keen about the reusability of services and performance.
83. Why use C++
● C++ is still widely used in the industry
due to
● Performance advantage of the native
code
● Flexibility available from object
oriented language
● Tight control over memory and CPU
84. Typical applications that use
C++
● Applications which require high
performance and the ability to handle
large volumes of data
● Financial Market Applications
● Large E-Commerce applications
● Banking Applications
● Telecommunication Systems
● Data Base Systems
● Applications which require tight control
over memory and CPU
● Operating Systems (C/C++)
● Embedded Systems
85. A UseCase
● A legacy C++ system which has been
performing useful work for a long time.
This has remained isolated while all other
systems in the organization evolved and
connected together.
�� Need to integrate this system with other
applications to use its functionality in a
broader perspective.
● Options
● Rewrite the system ( Costly )
● Integrate using EAI
● Integrate using a native Web Services Stack
86. A UseCase
SAP
.N E T
Legacy
System S e c u r e , R e lia b le , B in a r y
J2EE
W e b S e r v ic e s
C IC S
Java
88. Native Web Services Stack
● What would you look from a native web
services stack ?
● Support for Basic Web Services Standards
● Tooling for WSDL
● Portability
● Performance / Low memory foot print
● Security
● Ability to handle binary data
● Interoperability
● Asynchronous communication
89. Portability
● My legacy application is running on
platform 'X'. Does your Web Service
stack run on it ?
● It can boil down to multitude of issues
● Differences in operating system versions
● Differences in build tool versions, compiler
versions
● Dependency problems
90. Performance
● Performance is a broad area. Usually
Performance means response time. In
another way, how many requests can
the server handle per second
● However, performance depends on the
system's hardware as well as load on
the system
● Does the performance stay constant or
does it degrade over time
● How does the performance vary with
the size of the messages, load of the
system
91. Low Memory Foot Print
● Some servers take large amount of
memory just to start up
● How much memory does it require to
run efficiently ( Important in embedded
systems)
● Does the memory usage stay constant
while handling large xml messages,
large binary content
