NEW QUESTION # 436
What is a challenge of the SaaS model?
Answer: C
Explanation:
A major SaaS challenge is the lack of direct application and infrastructure control. With Software as a Service, the provider operates the application stack, platform, upgrades, and supporting infrastructure. The customer benefits from reduced maintenance burden and lower initial deployment cost, but gives up much of the direct control normally available with on-premises applications. This affects troubleshooting, change windows, performance visibility, customization, data residency controls, and integration with existing enterprise systems. Higher initial costs are usually not a SaaS characteristic; SaaS commonly shifts spending toward subscription operating expense. Client computer upgrades are not normally required in the same way as thick-client enterprise software. Data and application integration can be complex, but the option that best captures the core architectural challenge is reduced control over the application and infrastructure. Network architects must account for this by designing secure direct internet access, cloud monitoring, identity integration, and reliable paths to SaaS providers. Reference topics: SaaS architecture, cloud application control, enterprise cloud access, operational visibility, SD-WAN SaaS design.
