Synergy Research Group estimated that enterprise spending on cloud infrastructure services—Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and hosted private cloud—rose 35% to almost $130 billion. By contrast, enterprise spending on its own data-center hardware and software fell 6% to below $90 billion. The paired figures show both a pandemic-era surge and a longer shift from company-owned infrastructure toward cloud providers.
How much did cloud computing grow in 2020?
Synergy’s market estimate is the clearest single answer for enterprise infrastructure spending: cloud infrastructure services grew 35% in 2020, reaching nearly $130 billion. Enterprise data-center hardware and software spending moved in the opposite direction, declining 6% to less than $90 billion. In 2019, the two categories had been almost equal; in 2020, cloud services moved materially ahead.
The comparison covers different forms of infrastructure. Cloud services are rented capacity and platforms operated by providers, while the data-center category includes servers, storage, networking, security and associated software purchased for enterprise-owned facilities. Synergy’s account is documented in its March 18, 2021 analysis, “2020 – The Year that Cloud Service Revenues Finally Dwarfed Enterprise Spending on Data Centers.”
What the headline market number does—and does not—measure
“Cloud computing” is used for several overlapping markets. Synergy’s almost-$130-billion figure is not a total for every cloud application or subscription; it is specifically enterprise spending on IaaS, PaaS and hosted private cloud. A separate Information Technology and Innovation Foundation (ITIF) report put the broader global cloud services market at $270 billion in 2020. Those figures use different boundaries and should not be added together or treated as competing measurements of the same market.
#1 Best Overall
ITIF also estimated that cloud computing represented 7.2% of global IT spending in 2020. That proportion matters: adoption was widespread, but cloud still accounted for a minority of overall IT budgets. Many organizations were using cloud for selected workloads rather than running all of their technology there. ITIF’s June 2021 report is available at Cloud Computing: The First Stage of a Long-Term Revolution.
In the report’s excerpt of the NIST definition, cloud computing is “a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources … that can be rapidly provisioned.” The wording emphasizes shared, network-delivered resources that can scale faster than infrastructure bought and installed by one organization.

How fast did the major cloud providers grow?
Provider results reinforce the picture of strong growth, but they are not a clean league table. Each company reports a different period and category, so the period and metric must stay attached to the percentage.
| Provider | Reported 2020 result | Period and scope |
|---|---|---|
| Amazon Web Services (AWS) | Revenue grew 30% year over year, from a 2019 base of $35 billion | Calendar 2020 AWS revenue; Amazon said growth was slower than 37% in 2019 |
| Microsoft Azure | Revenue grew 56% | Microsoft fiscal year 2020; Microsoft attributed growth to consumption-based services |
| Google Cloud | Revenue grew 46%, an increase of $4.1 billion | Calendar 2020 Google Cloud revenue |
Amazon’s shareholder letter said business uncertainty and customers’ efforts to optimize their AWS footprints contributed to the slower growth rate, while companies were also accelerating cloud moves as they reassessed their infrastructure. The letter is available at Amazon’s 2021 Letter to Shareholders.
Rank #3
Microsoft’s 56% Azure figure is narrower than its “commercial cloud” measure. That broader bundle—which includes Office 365 Commercial, Azure, commercial LinkedIn, Dynamics 365 and other properties—increased 36% to $51.7 billion in Microsoft’s fiscal 2020. Microsoft reports these figures in its 2020 annual report.
Alphabet reported Google Cloud’s 46% calendar-year increase while continuing to invest in sales, product development and technical infrastructure. Its filing is available through the 2020 Form 10-K.
Why did cloud computing grow during the pandemic?
Remote work and learning changed demand quickly
Organizations that had previously operated mainly from offices needed staff to access applications and data from home. Microsoft’s 2020 annual report described increased cloud usage and demand in its Productivity and Business Processes and Intelligent Cloud segments as customers shifted to working and learning from home.
Online services consumed more infrastructure
Canalys reported $34.6 billion in global infrastructure-services spending in the second quarter of 2020, up 31% year over year. It linked record consumption to online collaboration, remote-working tools, ecommerce, remote learning and content streaming. The quarter was an early, concentrated snapshot of pandemic effects rather than a substitute for the full-year market estimate. Canalys’ report is available as a July 30, 2020 PDF.

Cloud became a way to adjust capacity
On-demand infrastructure let companies add or reduce computing resources without immediately buying and installing more servers. Amazon’s 2021 shareholder letter captured the strategic shift: “Many concluded that they didn’t want to continue managing their technology infrastructure themselves, and made the decision to accelerate their move to the cloud.” The statement is Amazon’s corporate commentary, not an independent measurement of every customer’s decision.

Growth was not uniform. Canalys noted a weakened economic outlook, slower large projects and customers keeping existing IT assets in service longer. Companies could increase usage of online services while delaying major migrations or optimizing the cloud capacity they already consumed. Amazon similarly cited customer optimization efforts as one factor behind AWS’s slower percentage growth.
These countervailing forces explain why a 35% market increase and high provider growth rates do not mean every cloud project accelerated. The pandemic amplified an existing migration trend; it did not create cloud computing from nothing, and it did not remove budget, timing or operational constraints.
What changed structurally after 2020?
The spending crossover is the most durable signal. Cloud infrastructure services moved from roughly parity with enterprise-owned data-center equipment in 2019 to a clear lead in 2020. Synergy Research Group’s John Dinsdale described the underlying pattern: “Over the last ten years we have seen a dramatic increase in computer capabilities, increasingly sophisticated enterprise applications and an explosion in the amount of data being generated and processed, resulting in an ever-growing need for data center capacity.” He added that Synergy estimated 60% of servers sold were going into cloud providers’ data centers rather than enterprise facilities. That 60% is Synergy’s stated estimate, not a universal independently verified share.

Pandemic conditions produced an abrupt increase in remote-access and online-service demand, while years of rising data volumes, more capable applications and provider-scale economics had already been moving infrastructure toward cloud operators.
Quick Recap
How to interpret the 2020 growth figures
- Use Synergy’s 35% and almost $130 billion when discussing enterprise cloud infrastructure services across the market.
- Use the under-$90-billion, 6%-decline figure when comparing cloud infrastructure with enterprise-owned data-center hardware and software.
- Label provider percentages by period and scope: AWS is calendar 2020, Azure is Microsoft fiscal 2020, and Google Cloud is calendar 2020.
- Do not compare Azure’s 56% directly with AWS’s 30% as if they were identical businesses; reporting periods and category definitions differ.
- Keep the broader context: ITIF’s $270-billion global cloud-services estimate and 7.2% share of global IT spending describe a wider market and show that cloud adoption was still incomplete.
