Cloud computing refers to the delivery of on-demand computing services including IT infrastructure, storage, network systems, and applications over the internet. Services are provided by a third-party vendor who handles the management and maintenance of the physical data centers where the cloud services live.
Cloud computing is the delivery of business tools and applications such as databases, software, and servers, among others, across the internet. These tools and applications are hosted remotely in data centers located in sites far removed from where the businesses are located and are delivered to end-user devices when needed. As businesses increasingly appreciate the cost savings, easy scalability as well as work flexibility offered by cloud computing, there has been a significant increase in its adoption over the past several years. Up from $196 billion in 2018, the worldwide market for cloud-based services is projected to increase to $354 billion by 2022, with over 60% of businesses using the cloud in one form or another.
