"Backed by many years of building mission critical real-world distributed systems it is no wonder that Udi is the best at what he does. When customers have deep issues with their system design, I point them Udi's way.”
Learn Advanced Distributed Systems Design
Join Udi Dahan for this extremely popular (and intensive) course on modern architecture design practices for distributed systems with Service-Oriented Architecture that will change the way you think about designing software systems.
Designing large-scale distributed systems is hard. While new technologies make it easier to comply with today's communications and security standards, they don't auto-magically give you a robust and scalable system. See how companies like Amazon and eBay run their systems and learn how to:
- Avoid common pitfalls in distributed systems
- Use loosely coupled messaging communication
- Identify and allocate business logic to services
- Decompose services into layers, tiers, assemblies, and processes
- Design for service management and monitoring in production environments
Who should attend?
This course is meant for 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
"The course profoundly changed our understanding and approach to SOA and distributed systems.”
"My biggest takeaway was that you really had to break all precocious notions of what good software development is when you develop distributed system.”
"I attended the ADSD course and it shook me to my foundations. It was a grueling five days of consuming from a fire hose.”
"Udi gave a lot of good examples of how we could implement the ideas slowly to get the business and stakeholders on board with using service-oriented architecture. Which we did!”
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.
- 8 fallacies of distributed systems
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.
- Platform Coupling
- XML/SOAPTemporal Coupling
- Synchronous/Asynchronous Spatial Coupling
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
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
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
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.
- Search & Queries + Denormalization
- Validation & Business Logic for commands
- Publish/Subscribe eventing for synchronizing denormalized caches
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
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
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
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
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.
Attending the course
Prerequisite for participating
To fully benefit from this course you should have some experience in developing complex software systems and a basic understanding of object-oriented design and rudimentary UML. You'll enjoy this workshop even more if you have prior experience with large scale application development involving object modeling and web services, but this is not essential.
What to expect from the daily schedule
The course runs Monday to Friday, starting at 8:30am till 6pm with lunch break and short breaks between sessions. On Tuesday and Thursday you will be given homework that you should complete for the next day.
What is included in the price
- 5 days of expert systems design training
- Hands-on group exercises to ensure maximum retention
- A video recording of the training course
