Key Notes
Happy Learning!!!
- Storage, Big Data, File Sharing
- The infrastructure that requires more than one computer
- High Performance, Parallelism
- Fault Tolerance - Two computer does the same things. One Fails another picks up. Availability / Recoverability, Replication
- Systems are inherently physically distributed
- To achieve security goals
- Handle unexpected failure patterns (Partial Failures)
- Challenges are Concurrency, Partial Failures
- Academic Curiosity -> Real-world Examples
- Lectures, Research papers for ideas, implementation details, labs, exams
- Map Reduce - Map Function on each of the input files, Obvious Parallelism available. The output is a list of Key-Value Pairs. Maps -> Intermediate Output -> Reducers. Collects all instances, all maps.
Happy Learning!!!
