Study Notes
System Characteristics
- Resiliency refers to the ability of a system to recover quickly and efficiently from failures or disruptions and continue functioning properly.
- Fault tolerance is the ability of a system to continue operating without interruption in the event of hardware or software failures.
- A reliable system is one that operates correctly, delivers expected performance levels, and meets user requirements without experiencing frequent failures, errors, or malfunctions.
Service Orchestration and Virtualization
- Service orchestration involves automatic creation of virtual machines.
- Softwarelisation is the process of resource pooling.
- Virtualization involves sharing CPU and network resources.
Physique and Redundancy
- Physique is used to resolve single point of failure problems.
- Redundancy is achieved through the rule of 3-2-1-0, which involves:
- 3 copies of data
- 2 support systems
- 1 offset (external support)
- 1 online system with 0 warnings
Service Level Agreement (SLA)
- SLA is a service level agreement that outlines the expected performance and service quality of a system.
