Agenda Not Set Yet Room Not Assigned
In the past, applications where created as monolithic entities running on a single server. If this is the past for you, too, you will have experienced the downside of modern distributed and cloud applications, as debugging, troubleshooting, and monitoring is not easily accomplished with traditional approaches. Within this session, we will explore different possibilities for collecting and analyzing the needed information to solve issues on modern distributed application and discuss the advantages and disadvantages of each approach like debugger, log files, performance counter and third party solutions. The focus of this session will be on Developer and DevOps need, as increased release cycles and third party dependency more and more result in the need for troubleshooting also on production system, rather than in an isolated test environment. This session requires a solid understanding of distributed applications and knowledge of SOA, but most principles also apply to and can be beneficial for more traditional application design approaches. The used code examples are in .NET but the shown principles generally apply to other languages, too, and shown software is often available for a variety of environments.

I have been designing and implementing .NET based applications, components and frameworks for more than 9 years, and I am currently working as a Senior Software Engineer at AppDynamics, one of the leading application performance management solutions for distributed application for web and cloud. My special interests are software architecture, framework and platform design, and writing Clean Code applying craftsmanship principles.

Consuming web services asynchronously with...
by Chris Richardson
Agenda Not Set Yet Room Not Assigned
A modular, polyglot architecture has many advantages but it also adds complexity since each incoming request typically fans out to multiple distributed services. For example, in an online store application the information on a product details page - description, price, recommendations, etc - comes from numerous services. To minimize response time and improve scalability, these services must be invoked concurrently. However, traditional concurrency mechanisms are low-level, painful to use and error-prone. In this talk you will learn about some powerful yet easy to use abstractions for consuming web services asynchronously. We will compare the various implementations of futures that are available in Java, Scala and JavaScript. You will learn how to use reactive observables, which are asynchronous data streams, to access web services from both Java and JavaScript. We will describe how these mechanisms let you write asynchronous code in a very straightforward, declarative fashion.

Chris Richardson is a developer and architect with over 20 years of experience. He is a Java Champion and the author of POJOs in Action, which describes how to build enterprise Java applications with POJOs and frameworks such as Spring and Hibernate. Chris is the founder of the original CloudFoundry.com and now spends his time investigating better ways to develop applications and evangelizing Cloud Foundry. He has a computer science degree from the University of Cambridge and lives in Oakland.

Using a RESTful (or Hypermedia) architecture, we've created "micro" services that talk to each other in order to provide scalability, along with ease of development, deployment, and management.

Standardizing Data Distribution Service API for...
by Sumant Tambe
Agenda Not Set Yet Room Not Assigned
This talk is about the “Whys” and “Hows” of the DDS-PSM-Cxx standard. The DDS-PSM-Cxx standard is among the family of standards around the core Data Distribution Service (DDS) standard for developing high-performance distributed real-time systems. DDS-PSM-Cxx provides a portable C++ API for programming DDS, which is modern, idiomatic, STL-friendly, expressive, safe, and efficient. DDS-PSM-Cxx targets C++03 but makes special provisions for ensuring forward portability in C++11 environment. The presentation will first describe what DDS is and why it matters. The objectives and the high-level structure of the DDS-PSM-Cxx standard will be described next along with a “Hello, World!” example. The talk will further describe interesting aspects of the standard, such as the support for drop-in replacement of conforming vendor implementations, syntactic cues for vendor-specific API extensions, and the use of various C++03 idioms to provide a clean, safe, and efficient API. We will discuss exception-safety considerations that shaped the standard in important ways. Finally, we will discuss the special rules that allow conforming C++03 applications be forward compatible in C++11 environment.

Sumant is working for Real-Time Innovations after a PhD in distributed systems and has been programming in C++ for nearly a decade. He enjoys working on standards-based data distribution middleware for real-time systems and using C++ to solve interesting problems ranging from systems to meta-programming. He believes that knowledge is gained by spreading it. So he blogs <a href="http://cpptruths.blogspot.com">C++ Truths</a> and writes <a href="http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms">Mor
