Study Notes
Cluster Computing
- Clusters are deployed to improve speed and/or reliability over a single computer, while being cost-effective.
- A typical cluster consists of:
- Network: Faster and closer connection than a typical LAN.
- Low-latency communication protocols.
- Loosely coupled nodes (unlike SMP).
Types of Clusters
- High Availability or Failover Clusters.
- Load Balancing Cluster.
- Parallel/Distributed Processing Clusters.
Cluster Components
- Cluster Nodes.
- Cluster Network.
- Network Characterization.
Key Operational Benefits of Clustering
- System availability: inherent high system availability due to redundancy of hardware, OS, and applications.
- Hardware fault tolerance: redundancy for most system components (e.g., disk-RAID).
- OS and application reliability: running multiple copies of OS and applications.
- Scalability: adding servers or clusters as needed.
- High performance: running cluster-enabled programs.
Utility Computing
- Purely a concept, practically implemented in cloud computing.
Cloud Computing
- Defined by the ACM Computing Curricula 2005 as any goal-oriented activity requiring, benefiting from, or creating computers.
Cloud Computing Overview
- Cloud computing stack:
- Infrastructure as a Service (IaaS).
- Platform as a Service (PaaS).
- Software as a Service (SaaS).
- Deployment Models.
- Service Management in Cloud Computing:
- Service Level Agreements (SLAs).
- Cloud Economics.
- Resource Management in Cloud Computing.
- Data Management in Cloud Computing:
- Scalability and Cloud Services.
- Database and Data Stores in Cloud.
Why Distributed Computing?
- Nature of application:
- Performance: computing-intensive tasks.
- Data-intensive tasks: large amounts of data processing.
- Robustness: no Single Point of Failure (SPOF).
Distributed Applications
- Consist of a set of processes distributed across a network of machines, working together to solve a common problem.
- Applications that consist of a set of distributed processes.
Grid Computing
- A form of networking for large-scale data processing.
Cloud Security
- Infrastructure Security.
- Data Security and Storage.
- Identity and Access Management.
- Access Control, Trust, Reputation, Risk.
Evolution of Cloud Computing
- Business drivers for adopting cloud computing:
- Reducing IT costs.
- Scalyability and rapid resource provisioning.
- Economics of cloud computing:
- In-house server vs. cloud server costs.
- Efficiency and cost-effectiveness of cloud computing.
Benefits of Cloud Computing
- High utilization.
- Scalability.
- No separate hardware procurement.
- No separate power cost.
- No separate IT infrastructure administration/maintenance required.
- Public clouds offer user-friendly SLA by offering high availability (~99%) and compensation in case of SLA miss.
