Cloud Computing Assignment -1

Study Notes

No up-front commitments allow organizations flexibility in usage without large initial investments.
On-demand access facilitates resources being available as needed, enhancing operational efficiency.
Competitive pricing reduces the financial burden associated with traditional IT infrastructure.
Simplified application acceleration and scalability enable businesses to adapt quickly to changing demands.
Efficient resource allocation optimizes usage, leading to improved performance and cost savings.
Energy efficiency contributes to lower operating costs and aligns with sustainability goals.
Seamless integration of third-party services broadens functionality without complex setups.

Reduced maintenance and operational costs lead to increased economic returns for organizations.
IT assets are converted into utility costs, paid as used, eliminating upfront capital expenditures.
Capital costs associated with hardware and software were historically significant but are minimized through cloud services.
By converting IT infrastructure to operating expenses, businesses can improve their net gains without depreciation concerns.
Small organizations and startups benefit from the lower entry costs, supporting growth without major financial risks.

Virtualization emerged from mainframe technology, notably IBM's CP/CMS systems, introducing hardware virtualization and hypervisors.
Allows multiple operating systems to run concurrently on a single host, optimizing resource use and reducing costs.

Increased Security: Virtual machines create secure environments by controlling and filtering guest operations to prevent harmful activities.
Resource Shelling: Sensitive host information can be easily hidden from virtual environments without complex security setups.
Sandboxing: Technologies like the Java Virtual Machine (JVM) utilize sandboxing for untrusted code applications, enhancing security.

Partial Virtualization: Provides limited emulation of hardware, supporting multiple applications but with restrictions on the complete operating system execution.
Operating System-Level Virtualization: Creates isolated user space instances within a single OS, improving resource management without needing a separate hypervisor.

The Java platform and .NET Framework have become essential for enterprise applications, both utilizing stack-based virtual machines for efficient execution.
Just-in-Time (JIT) compilation enhances performance in virtual machines by compiling bytecode to machine code on demand, optimizing future executions.
Common Language Infrastructure (CLI) supports various programming languages, promoting interoperability and developer engagement.
