Research Outline

Cloud Computing


To provide an explanation of cloud computing, 10 statistics on cloud usage and growth, a list of industries where it is used most, a list of industries where it is predicted to grow, a list of use cases, key providers, 8 ways in which cloud computing will affect consumers in the future, and 8 ways in which it will affect businesses in the future.

Early Findings

Cloud Computing: Explanation Statistics

  • According to Accenture, "cloud is a model of computing where servers, networks, storage, development tools, and even applications (apps) are enabled through the internet. Instead of organizations having to make major investments to buy equipment, train staff, and provide ongoing maintenance, some or all of these needs are handled by a cloud service provider."
  • A cloud computing environment has five characteristics: internet access, measured service, on-demand self-service, shared resource pooling, and rapid elasticity. Details of each characteristic may be found here.
  • The global market for cloud computing is projected to be $623.3 billion by 2023, growing at a CAGR of 18%.
  • Enterprises run 46% of their workloads in private cloud and 33% in public cloud while SMEs run 43% on public cloud and 35% on private cloud. Statistics also suggests that usage of public cloud is growing three times faster than that of private cloud, thus suggesting disparity in future growths.
  • According to the International Data Corporation (IDC), global spending on public cloud services and infrastructure was estimated to be $210 billion in 2019, a 23.8% increase from 2018. It is projected to reach $370 billion in 2022, growing at a five-year CAGR of 22.5% from 2017.
  • There are three types of cloud services: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS).
  • According to a 2018 survey by the International Data Group (IDG), "[73%] of organizations have at least one application, or a portion of their computing infrastructure already in the cloud — 17% plan to do so within the next 12 months."
  • The survey also finds a mix use of cloud delivery models, with "the average environment is 53% non-cloud, 23% SaaS, 16% IaaS and 9% PaaS; however, will evolve to only 31% non-cloud within 18 months."
  • The same survey conducted two years later (2020) finds that "92% organization’s IT environment is at least somewhat in the cloud today."
  • It projects that cloud-first applications may become more prevalent over time, with "46% of organizations' [current] cloud-based applications were purpose built for the cloud as 54% moved from an on-premises environment."
  • Among organizations surveyed in 2020, 55% currently use multiple public clouds, with 21% using three or more.
  • According to a projection by Cisco, cloud data center traffic will make up 95% of total data center traffic by 2021, an increase from 88% in 2016.
  • Cisco also predicts that cloud data centers will process 94% of all workloads and compute instances while traditional data centers will process only 6% by 2021.


The initial one-hour research has provided a brief explanation of cloud computing and more than 10 statistics on its current and projected usage and growth. However, there is a lot more to cover, including key providers and the future impact of cloud computing on consumers and businesses. Please select from the following proposed next steps.
