Norvik Bank currently runs a bespoke core application on IaaS and employs a large operations team for patching and scaling. The CIO proposes moving to a PaaS platform. The audit committee asks about the strategic implications. Which statement is most accurate?

The most accurate statement is that operational overhead should fall because the provider manages the operating system and runtime, but vendor lock-in risk rises because applications become dependent on the platform's proprietary tools. Regulatory accountability for data stays with the bank.

  1. AOperational overhead should fall, but Norvik may face greater vendor lock-in because the application becomes tied to the platform's tools and servicesCorrect
  2. BOperational overhead should rise because PaaS requires the customer to manage the operating system
  3. CVendor lock-in falls because PaaS applications run unchanged on any provider
  4. DNorvik transfers all regulatory accountability for data to the PaaS provider

Explanation

PaaS shifts operating system and runtime management to the provider, reducing operations workload and speeding deployment. The trade-off is dependence on proprietary platform services, raising lock-in and portability risk. Regulatory accountability for customer data stays with the bank, and PaaS does not add OS management.
