Cloud-based distributed systems are collections of interconnected servers and resources that work together to provide scalable, reliable, and efficient computing services. These systems distribute tasks across multiple nodes to handle large-scale data processing and storage, taking advantage of cloud infrastructure to ensure flexibility and elasticity. However, they face several common challenges: Spill, Skew, Shuffle, Storage, and Serialization. Addressing these challenges is essential for efficient and reliable operation of cloud-based distributed systems. Implementing optimization and management techniques can enhance performance and scalability.In this Webinar we will be discussing 5 common issues that impact performance and stability in Cloud based Distributed Systems. ### PowerPoint Slide Script: Optimizing Cloud-Based Distributed Systems. They are Spill, Shuffle, Storage, Skew, and Serialization.
Spill Occurs when a system runs out of memory and uses disk storage to handle overflow data. Spill significantly slows down processing times due to slower read/write speeds of disks compared to memory. Mitigation techniques include:
- Efficient memory management
- Data partitioning
- Caching techniques
Shuffle Redistributes data across nodes during operations like sorting and grouping, crucial in distributed data processing. This leads to high network I/O and increased latency, especially over long distances.
Mitigation techniques include:
Minimize shuffle operations
Optimize data locality
Use efficient serialization formats
Storage relies on distributed storage for large datasets, needing reliability, scalability, and performance. Poor storage planning impacts the entire data pipeline. Mitigation techniques include:
Proper partitioning
Optimize data locality
Use efficient serialization formats
Skew indicates uneven data distribution across nodes, causing some to handle more data than others
This Results in load imbalance and bottlenecks. Mitigation techniques include:
Data partitioning
Load balancing
Adaptive query processing
Serialization involves converting data structures into a format for storage or transmission and later reconstruction.
Unnecessary serialization can cause Inefficient formats increase data size, leading to higher network I/O and longer processing times. Mitigation techniques include:
- Use compact serialization formats (e.g., Protocol Buffers, Avro)
- Optimize serialization/deserialization processes
