These days - we all have tons of apps installed on our mobile and getting lot more apps has always been a dream to many of us. But what is really stopping to keep adding apps is the memory, space , performance constraint on our mobiles. Relating this to our cloud era- when our on-premise data centers had challenges in scaling up ; we heard that cloud is the solution - so that it allows us to scale up , pause , save money as needed; why cant we have similar concept for mobile apps to ? Why cant Microsoft offer a Virtual space ( like Windows VM) - where it can have enough space , memory and we can install all required apps to it ; in fact this can be used more in corporate world to set all corporate apps ( outlook, power BI, ticket creation, IT solutions, ) and make their employees privileged/happy of not using their personal mobile space/memory to install apps related to work :)
