In a distributed system, components running on different Operating Systems and applications written in different programming languages all work together as one single reliable system. As the complexity of these systems increase, it becomes more important to gain visibility into your environment and expose potential problems before they jeopardize your production system. RTI Connext Tools offer a rich tools suite that helps you develop applications more efficiently. They enable you to monitor, analyze and debug your complete system in operation. And they provide facilities for recording and replaying data in real-time, and logging diagnostic system data for deeper analysis and archiving. This webinar explores the many tools available for development, debugging, and testing applications in your distributed system.

4. Decentralized Architecture
Network
• No central ESBs, brokers or servers
• Peer-to-peer communication
– Components, services, applications, devices, subsystems, s
ystems
• Bus is virtual

Virtual global data space
• Underlying communication paradigm
• Applications operate on data objects
– Create, Read, Update, Delete (CRUD)
– Like a database but for data in motion (event-driven)
• State maintained by middleware, external to apps

7. Benefits of Data Centricity
• Scalability and robustness
– Single source of truth in a system
– Late joining applications automatically synchronized
– Particularly valuable for dynamic OT systems
• Loose coupling for ease of development and integration
– Applications require no knowledge of each other
– …only of the data being exchanged
– Interfaces (types) and objects are well defined and discoverable
– Fosters information sharing, interoperability and open architecture
• Simplified development
– OT apps are inherently data centric
– Middleware manages data cache and lifecycles, not custom code
• Wire efficiency and performance
– No need to send field definitions with each message

14. Example QoS
• Reliability • History
• Durability • Lifespan
• Deadline • Liveliness
• Filtering • Ownership & Strength
– Time • Resource Limits
– Content
• Eases development and integration by moving logic
from application to middleware
• Improves efficiency and scalability: only required data
is sent and delivered data

15. Quality of Service Compatibility
• QoS Example - Deadline
– The Deadline QoS specifies the maximum time
between data sample
– Writer uses this to specify a new data sample will
be published at least every x seconds
– Reader uses this to specify they want to receive
one data sample at least every x seconds
