The cloud computing business had increased during the Covid-19 Pandemic due to the urgent need to store/share the data for companies and businesses.  76% of IT professionals were dependent on public cloud providers as they were working remotely. 

Nowadays, every big or small company depends on cloud computing systems to store their important data and share their resources with their users. Investing in private clouds for companies makes them wasting money in maintaining, buying, installing, and operating servers.
