Choose all the correct alternatives about Case Study #$1,$ considering that Innovartus is currently using PaaS.

Group of answer choices

If Innovartus was using LAMP, moving to a SaaS provider could introduce certain technical challenges but it would be a feasible technical solution that would not require redeveloping Innovartus' applications.

Moving to Amazon or other IaaS cloud provider would require Innovartus to redevelop its applications, so the best option would be to use another PaaS. As such, a PaaS provider could be able to provide the same ready$-$made environment Innovartus is currently using.

Moving to Amazon or other IaaS cloud provider would introduce new challenges to the technical team in terms of administrative responsibilities. However, it would not necessarily require changes in Innovartus applications if they could reproduce the current platform in the new IaaS provider.

Moving to Amazon or other IaaS cloud provider would require Innovartus to redevelop its applications. IaaS providers can only provide ready$-$made environments and it is unlikely they would have exactly the same stack that Innovartus has now.
