Study Notes
Cloud Computing Overview
- Cloud computing delivers computing, storage, and software as services, making it a foundational concept in ICT.
- It consists of interconnected, virtualized systems dynamically provisioned as unified computing resources guided by Service Level Agreements (SLAs).
Key Characteristics of Cloud Computing
- Provides an illusion of infinite resources with flexible scalability.
- Eliminates upfront commitments, allowing clients to pay only for what they use.
- Ensures rapid provisioning and release of computing resources with minimal management intervention.
Definitions and Frameworks
- NIST defines cloud computing as a pay-per-use model for on-demand network access to a shared pool of configurable resources.
- Service-Oriented Architecture (SOA) facilitates loosely coupled service integration, promoting efficient distributed computing.
Web Services and Integration
- Web services enable applications to communicate across different platforms, promoting software integration.
- A rich stack of web service standards exists, allowing for the orchestration and management of services to meet business needs.
Resource Management and Utility Computing
- Utility computing allows users to assign a utility value to jobs, reflecting their willingness to pay based on QoS constraints.
- Service providers can prioritize jobs based on perceived utility, creating a competitive resource marketplace.
Hardware Virtualization
- Data centers utilize hardware virtualization to optimize resource sharing and operational efficiency.
- Virtual Machine Monitors (VMM) or hypervisors manage access to physical hardware, enabling multiple operating systems to operate on a single platform.
Prominent Cloud Management Solutions
- Eucalyptus offers features for virtual infrastructure management with compatibility for EC2 and S3 interfaces.
- Nimbus enhances cloud management through the Globus framework, providing a WSRF interface and support for local resource management.
- OpenNebula is noted for its comprehensive features, supporting both local and public cloud infrastructures with a modular architecture for flexibility.
Change Management in Cloud Computing
- Organizational readiness and change management are critical for adopting cloud technologies.
- Several change management models exist to assist organizations in navigating transitions in the cloud age.
Data Security Concerns
- Data security remains a significant challenge in cloud computing, requiring careful consideration of privacy, risk, and identity management.
Legal and Compliance Issues
- Legal frameworks surrounding data privacy, security, and jurisdictional challenges are essential for cloud computing users to understand.
Production Readiness for Cloud Services
- Achieving production readiness involves assessing service management, consumer relationships, and the full service lifecycle to ensure dependable operations.
