How to Assess the ROI of Your Population Health InitiativeHealth Catalyst
In the brave new world of value-based healthcare, investing in population health management (PHM) is a requirement for success. Defining PHM isn’t easy, but there is one common term that appears among all the diverse interpretations—outcomes. Assessing the potential ROI for investments in PHM using a clear, understandable framework, can help organizations methodically identify and prioritize their PHM investments. While not every PHM intervention makes sense for every situation, it is important to determine which programs provide the most benefit, as well as determining when the investment will begin paying dividends, to achieve success in the era of PHM.
The presentation describes in brief the patients need, expectations and how to develop the patient care and feedback system to obtain maximum patient satisfaction.
In Pursuit of the Patient Stratification Gold Standard: Getting There with He...Health Catalyst
Even the healthiest among us would benefit from some level of care management, but resources are limited and patients must be stratified to facilitate prioritized enrollment into care management programs. Therefore, health systems need to identify not only high-cost, high-risk, and rising-risk patients, but also patients who are truly impactable.
This article explains how systems can use healthcare analytics, at varying levels of maturity, to improve patient stratification and, ultimately, achieve the gold standard:
Level 1 (where to start): use healthcare analytics to identify high-cost, high-risk patients in a population.
Level 2: use healthcare analytics to identify patients with rising-risk profiles.
Level 3 (highest level of maturity): use healthcare analytics to identify patients who are truly impactable (the patient stratification gold standard).
Analytics is key to achieving the patient stratification gold standard, but should enhance (not replace) clinical judgement. Stratification lists need to go through workflows in which clinicians remove patients that aren’t appropriate for enrollment.
Healthcare Information Systems - Past, Present, and FutureHealth Catalyst
The document discusses the evolution of healthcare information systems from the 1960s to present day. It begins with early systems focused on hospital accounting and administrative functions. Over time, systems expanded to support clinical departments, integrated hospital operations, and began incorporating patient data. The proliferation of these transaction systems created large amounts of siloed healthcare data. Today, chief information officers are under pressure to implement enterprise analytics solutions to merge this data and drive performance improvement through analysis of comprehensive clinical and operational information.

Less Is More: Utilizing Ballerina to Architect a Cloud Data PlatformWSO2
At its core, the challenge of managing Human Resources data is an integration challenge: estimates range from 2-3 HR systems in use at a typical SMB, up to a few dozen systems implemented amongst enterprise HR departments, and these systems seldom integrate seamlessly between themselves. Providing a multi-tenant, cloud-native solution to integrate these hundreds of HR-related systems, normalize their disparate data models and then render that consolidated information for stakeholder decision making has been a substantial undertaking, but one significantly eased by leveraging Ballerina. In this session, we’ll cover:
The overall software architecture for VHR’s Cloud Data Platform
Critical decision points leading to adoption of Ballerina for the CDP
Ballerina’s role in multiple evolutionary steps to the current architecture
Roadmap for the CDP architecture and plans for Ballerina
WSO2’s partnership in bringing continual success for the CD
The integration landscape is changing rapidly with the introduction of technologies like GraphQL, gRPC, stream processing, iPaaS, and platformless. However, not all existing applications and industries can keep up with these new technologies. Certain industries, like manufacturing, logistics, and finance, still rely on well-established EDI-based message formats. Some applications use XML or CSV with file-based communications, while others have strict on premises deployment requirements. This talk focuses on how Ballerina's built-in integration capabilities can bridge the gap between "old" and "new" technologies, modernizing enterprise applications without disrupting business operations.

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.

Can I use WSO2 ESB?
18
19. Usage scenarios
Link legacy files to messaging based systems
Transform CSV or EDI formats to XML
Act as a high-performance XML Gateway
Content-based routing and creating virtual
services
Integrate FIX based trading systems with XML
and non-XML backends
Log, trace and audit live systems
19
20. Tell me some of the
main features of WSO2 ESB
20
42. Important concept – Send Mediator
• Used to send out the messages
• Used in almost all the cases
• Wrapped an endpoint
– if no endpoint is specified, anonymous 'To'
address will be taken as the EPR
42
43. Important concept – Sequence
• Special mediator
– List of mediators to be executed in an order
• Pipeline pattern
• Special sequences
– main
– fault
43
44. Important concept – operation modes
• Act as a proxy
• Main Sequence
– If none of the proxy services matches the
request pattern
44
45. I would like to have few
more mediator examples..
45
46. Extendibility – Java Mediator
• Class implementing the Mediator interface
– Or AbstractMediator class
– Custom mediator is executed through the
ClassMediator in ESB
– Corresponding setter methods in the custom class
will be set before executing the custom mediator
if any properties are specified
46
47. Extendibility - POJOCommand
• Extends the mediation capabilities using the
well known command pattern
– Class implementing the Command interface or
a POJO with a void execute() method
– execute() method will be invoked using the
Command interface or by using reflection
– Sets the properties before execution and
retrieves the properties after execution
47
48. Extendibility – Script Mediator
• Enables scripting for extending mediation
• Supports all the Apache BSF scripting languages
– JRuby, Jython, Groovy, Java Script
• Embed the script inline or can be referred to a
separate script file with the function name to
be executed
48
49. Extendibility – Spring Mediator
• Spring configurations to extend the mediation
• Spring bean must implement the Mediator
interface
• Refer to the spring application context using
the key
• The Spring bean is managed by the spring
context at mediation time
49
50. Extending WSO2 ESB
Registry as a repository
– Loading configuration from external registry
New Transports
50
51. So how does all of these fit
together?...
What happens with-in WSO2
ESB?
51
55. Performance
Completely asynchronous architecture internally
Streaming support for messages
100% error free and zero memory leaks under heavy load
Up to 4500tps out-of-the-box for proxying
– Intel(R) Xeon(TM) 3.20GHz 2MB Cache
– Dual Core - 2 CPU system
– 2GB RAM
– 1Gb Ethernet

57. Non-Blocking IO
Synapse
Incoming req
Request
Thread1 processing Outgoing req
Socket open
Socket open
TIME
TIME
TIME
TIME
Incoming resp
Response
Thread2 processing
Outgoing resp
This model means:
1. Synapse threads never blocked during normal processing
2. Number of sockets open >> number of threads
57
58. Monitoring
Monitor System statistics
Running logs
Message Tracing
Dynamically configurable Logger
Exposes statistics via JMX
Dashboard – Google Gadgets

59. I would like to see some
Use cases where all of
these are applied...
59
60. Use Case 1
• Problem
– I want to send a notification email whenever there
is a request to a particular service which satisfies a
set of conditions over the request
• Solution
– Filter the messages over the request and evaluate
the conditions
– If the conditions evaluate to true then clone the
message
– Send the request to the desired endpoint while
forwarding a copy (may be after transformation) 60
through the mail transport
63. Use Case 2
• Problem
– I have a service exposed over HTTP transport and
now I want the same service to be accessed through
JMS
• Solution
– Expose a proxy service with JMS (and what ever
transport) and switch the transport to HTTP (if not
http)
– Invoke the actual service with HTTP transport
– Switch the transport back to JMS of the response
message 63
66. Use Case 3
• Problem
– I want the ESB to invoke several services of the
same type for a request, evaluate all the responses
and respond me with the best one
• Solution
– Clone the message and send the requests to
different endpoints
– Get the responses from all services and aggregate
the responses
– Select the best out of the aggregated responses and
respond to the client
66
73. Use Case 4
• Problem
– I have a non secure service and now I want to
expose this service with security
• Solution
– Expose a proxy service
– Add security to that proxy service and specify the
policy on which you want to enforce security
– Invoke the actual service without security by
removing security headers in the request comes to
the proxy
– Add security for responses from the actual service 73
to client
76. Use Case 5 - FIX to HTTP transport
