Enterprise Development with NServiceBus
Duration: 2 days
Introduction
Developing systems for the enterprise brings with it many challenges that traditional RPC approaches like web services and WCF have failed to address. Scalability and availability are the two better known quality attributes of the enterprise, but fault-tolerance and reliability are just as critical to prevent data loss and inconsistencies. Join Udi Dahan as he describes the principles and patterns which address these topics, and see how NServiceBus – a framework implementing these principles and patterns, can be used to unify and simplify things like transactions, threading, messaging, monitoring, and versioning. The most popular open-source service bus for .NET, NServiceBus has already seen many production deployments by leading companies in finance, healthcare, retail, SaaS, web 2.0, and more.
Enterprise development – done right.
Audience
.NET developers working on distributed systems and in enterprise environments.

Advanced Distributed Systems Design using SOA & DDD
Duration: 5 days
Introduction
Designing large-scale distributed systems is hard. New technologies make it easier to comply with today’s communications and security standards, but don’t auto-magically give you a robust and scalable system. Join Udi for a course packed with the wisdom of companies like SUN, Amazon, and EBay.
Tried-and-true theories and fallacies will be shown, keeping you from making those same costly mistakes today. Communications patterns like publish/subscribe and correlated one-way request/response will be used in conjunction with advanced object-oriented state management practices for long-running workflows. If you enjoy deep architectural discussion, if you are in charge of building a large-scale distributed system, if you want to know more about how the big guys run their systems, this is for you.
Audience
This workshop is targeted at team leads, application and solutions architects, as well as technologists who are involved in making decisions about the overall system design of software products and projects.
Course Topics
Module 1: Distributed Systems Theory
Decades of distributed systems development have taught us many lessons. In this module we’ll cover many historical mistakes as well as proven best practices for scalable and robust design. Topics include:
- 8 fallacies of distributed systems
- Transactions
Module 2: Coupling: Platform, Temporal, & Spatial
Loose coupling has become the watchword of complex systems development, yet few understand its multiple dimensions. In the module we’ll be covering the three different dimensions of coupling as well as patterns for dealing with them.
Module 3: Asynchronous Messaging Patterns
Although scalability is achieved through the use of asynchronous message passing, more advanced message exchange patterns are required to handle today’s complex integration scenarios. This module will cover the most commonly used patterns:
- One way
- Correlated Request/Response
- Publish/Subscribe
Module 4: Bus & Broker Architectural Styles
Enterprise Service Buses are all the rage these days. In this module we’ll be covering what’s the difference between the Bus architectural style, and the more well-known Broker, found commonly in many EAI projects. Topics will include:
- Architectural advantages and disadvantages
- Technological advantages and disadvantages
Module 5: SOA Building Blocks
One of the goals of SOA is to develop systems which are more closely aligned with Business. In this module we’ll be covering an analysis methodology from moving from the business domain to executable systems that comply with all the principles of loose-coupling.
- Business Services
- Business Components
- Autonomous components & Queues
Group Analysis Exercise
In order to ensure maximum retention, students take part in a group analysis of an enterprise problem domain, identifying business services and events, experiencing first hand the tacit knowledge of parts of a solution that “feel right” and follow the rules outlined in the previous modules, as well as the other parts that “feel wrong”. Many students have described this exercise as the point of epiphany, when all the previous information “just made sense” afterward.
Module 6: Service Structure & CQRS
Drilling inside Business Services and Business Components, the topic of Command/Query Responsibility Segregation is introduced for designing collaborative, high-scale systems with great user experience. The connection between capturing user intent in task-based UIs, caching, and one-way messaging is described.
Topics include:
- Search & Queries + Denormalization
- Validation & Business Logic for commands
- Publish/Subscribe eventing for synchronizing denormalized caches
Module 7: Scalability and Flexibility
In order to enable agility, services must be able to scale up, out, and down quickly. In this module we’ll see how queues simplify monitoring solutions while at the same time connecting them to service-level agreements, as well as how this architecture can be capitalize on the capabilities of the cloud in order to create self-tuning systems.
- Scaling heterogeneous server farms
- Monitoring queues for SLA
- Rolling deployment and versioning
Module 8: Long running processes
The distributed communications patterns wouldn’t be complete without a discussion on orchestration. In this module we’ll see how to manage the state of long-running distributed communication flows as well as:
- Encapsulating process logic
- Advantages & disadvantages of orchestration
- The connection of time and messaging
Module 9: Service Layers and Domain Models
Logic-rich services require the use of advanced techniques for logic componentization. The Domain Model Pattern enforces a high level of Separation of Concerns, yet it must eventually be connected with Service Layer code that supports many concurrent users. In this module, the topics covered will include:
- Business Logic inside and outside a Domain Model
- Transactions, Isolation Levels, Concurrency Models
- Testing Domain Models
Module 10: Ultra-scalable Web Apps
As more web apps are put under the pressure of growing user bases, performing more complex tasks upon larger quantities of data, standard caching techniques are not able to handle the task by themselves. In this module, students will learn how to leverage the entire web as a cache, use Content Delivery Networks, in combination with the messaging shown in previous modules:
- Composability & Cacheability of dynamic content
- Scalable personalized data
- Integrated messaging & pub/sub for caching sensitive data
Module 11: Smart & Occasionally Connect Clients
The publish/subscribe semantics with which services communicate require smart clients to perform a great deal of background work. In this module, solutions will be shown to avoid multi-threaded deadlocks, livelocks, and data-races, as well as other best practices in smart-client development like:
- Client-friendly Service Contracts
- Service Agents and Client Repositories
- Highly interactive map-based UIs
Module 12: Summary & Review
In order to make sure that attendees are able to put into practice all that they’ve learned throughout the course, here we strengthen the seams between the various topics. Q&A is also a core part of this final section.
Reviews
Simon Segal, CTO at IT Results Pty Ltd
“When I had the privilege of sitting through this training I did so with my team and cant say enough about how it invigorated, improved and turbo charged the mind-set and output of all who attended. Udi is a very skilful presenter and a wonderful teacher and significantly has amassed some great wisdom that anyone who is serious about building Service Oriented systems should go out of their way to experience and imbibe.”
Aaron Jensen, VP of Engineering at Eleutian Technology
“Awesome. Just awesome.
We’d been meaning to delve into messaging at Eleutian after multiple discussions with and blog posts from Greg Young and Udi Dahan in the past. We weren’t entirely sure where to start, how to start, what tools to use, how to use them, etc. Being able to sit in a room with Udi for an entire week while he described exactly how, why and what he does to tackle a massive enterprise system was invaluable to say the least.
We now have a much better direction and, more importantly, have the confidence we need to start introducing these powerful concepts into production at Eleutian.”
Ray Houston, Director of Development at TOPAZ Technologies
“Udi’s SOA class made me smart – it was awesome.
The class was very well put together. The materials were clear and concise and Udi did a fantastic job presenting it. It was a good mixture of lecture, coding, and question and answer. I fully expected that I would be taking notes like crazy, but it was so well laid out that the only thing I wrote down the entire course was what I wanted for lunch. Udi provided us with all the lecture materials and everyone has access to all of the samples which are in the NServiceBus trunk.
Now I know why Udi is the “Software Simplist.” I was amazed to find that all the code and solutions were indeed very simple. The patterns that Udi presented keep things simple by isolating complexity so that it doesn’t creep into your day to day code. The domain code looks the same if it’s running in a single process or if it’s running in 100 processes.”
