Performance bottleneck and single point of failure are limitations of which pattern
Answers
Performance bottlenecks can lead an otherwise functional computer or server to slow down to a crawl. The term “bottleneck” refers to both an overloaded network and the state of a computing device in which one component is unable to keep pace with the rest of the system, thus slowing overall performance
A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. SPOFs are undesirable in any system with a goal of high availability or reliability, be it a business practice, software application, or other industrial system.
these two fails (either by hardware or software), all process instances will fail.
For example, when data generated by one service is important for another service, this data will be routed through the central coordinator (from the first service to the second service), even if this data is of no impor- tance to the coordinator. This creates a lot of unnecessary network traffic from and to the central coordinator (see Fig. 3b). Performance bottleneck. Real life processes can build up in scale and complexity and for one process description, multiple process instances can be created (see Fig. 3c). In process intensive organizations, these process instances can run up very quickly. When all the instances are coordinated at one point in the IT infrastructure,
Performance bottleneck and single point of failure are the limitations of broker pattern.
Single point of failure and Performance bottleneck is a part of the system makes the other operation to fail in case if it doesn't work. that, if it fails, will stop the entire system from working.
These are undesirable one in any kind of hardware or software system.
