Question
A network engineer is implementing a solution by which on-premises servers are migrated to a cloud service provider. Which of the following service models will provide a lift and shift solution to meet this requirement?
Options
- AInfrastructure as a service
- BInfrastructure as code
- CSoftware as a service
- DSoftware-defined network
Explanation
Infrastructure as a Service (IaaS) is the cloud service model that provides virtualized computing resources, such as virtual machines, networks, and storage, making it ideal for "lift and shift" migrations where existing on-premises applications and operating systems are moved to the cloud with minimal changes.
Common mistakes.
- B. Infrastructure as Code (IaC) is a practice of managing and provisioning infrastructure through code, not a cloud service model, and while it can be used with IaaS, it doesn't define the service model for migration.
- C. Software as a Service (SaaS) delivers complete, ready-to-use applications over the internet, which is typically for consuming existing software, not migrating custom on-premises servers and applications in a "lift and shift" manner.
- D. A Software-Defined Network (SDN) is an architectural approach to networking that allows dynamic, programmatic network configuration, which is a technology but not a cloud service model for migrating servers.
Concept tested. Cloud service models (IaaS)
