Case Study #$1-$ Innovartus

$1-$ Introduction

The primary business line of Innovartus Technologies Inc. is the development of virtual toys and educational entertainment products for children.

These services are provided through a Web portal that employs a role$-$playing model to create customised virtual games for PCs and mobile devices. The games allow users to create and manipulate virtual toys $($cars$,$ dolls, pets$)$ that can be outfitted with virtual accessories that are obtained by completing simple educational quests. The main demographic is children under $12$ years.

Innovartus further has a social network environment that enables users to exchange items and collaborate with others. All of these activities can be monitored and tracked by the parents, who can also participate in a game by creating specific quests for their children.

The most valuable and revolutionary feature of Innovartus$$ applications is an experimental end$-$user interface that is based on natural interface concepts. Users can interact via voice commands, simple gestures that are captured with a Webcam, and directly by touching tablet screens.

The Innovartus portal has always been cloud$-$based. It was originally developed via a PaaS platform and has been hosted by the same cloud provider ever since. However, recently this environment has revealed several technical limitations that impact features of Innovartus$$ user interface programming frameworks.

$2-$ Technical Infrastructure and Environment

Many of Innovartus$$ other office automation solutions, such as shared file repositories and various productivity tools, are also cloud$-$based.

The on$-$premise corporate IT environment is relatively small, comprised mainly of work area devices, laptops, and graphic design workstations.

$3-$ Roadmap

After a round of meetings with the stakeholders, Innovartus has decided to continue building upon its cloud$-$based solutions; however, the current cloud hosting environment has limitations that need to be overcome:

$-$ scalability needs to be improved to accommodate increased and less predictable cloud consumer interaction;

$-$ service levels need to be improved to avoid outages that are currently more frequent than expected;

$-$ cost effectiveness needs to be improved, as leasing rates are higher with the current cloud provider when compared to others.

These and other factors have led Innovartus to decide to migrate to a larger, more globally established cloud provider.hoose all the correct alternatives about Case Study #$1,$ considering that Innovartus is currently using PaaS.

Group of answer choices

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.

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. IaaS providers can only provide ready$-$made environments and it is unlikely they would have exactly the same stack that Innovartus has now.

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.
