  • Fixed Capacity: Capacity is limited to physical infrastructure, leading to potential underutilization or over-provisioning.

Maintenance and Administration

  • In-House Expertise: Requires skilled IT personnel for maintenance, troubleshooting, and upgrades.
  • Responsibility: Organizations are responsible for all aspects of system administration and support.

Cloud Virtualization

Cloud virtualization involves leveraging virtualization technologies provided by cloud service providers (CSPs) via the internet. Here’s what you need to know about cloud-based virtualization:

Resource Access and Management

  • Resource Pooling: Access to shared pools of virtualized resources (compute, storage, network) based on subscription models.
  • Managed Services: CSPs handle underlying infrastructure maintenance, updates, and security patches.

Scalability and Elasticity

  • On-Demand Scaling: Instantly scale resources up or down based on workload demands.
  • Pay-as-You-Go: Pay only for the resources utilized, reducing upfront costs and optimizing expenditure.

Security and Compliance

  • Provider Security Measures: Relies on CSPs’ security protocols and compliance certifications.
  • Data Location: Data sovereignty concerns due to potential data residency regulations.

Disaster Recovery and Business Continuity

  • Built-in Redundancy: CSPs offer built-in backup and disaster recovery options.
  • Geographic Redundancy: Data replication across multiple regions for fault tolerance.
