Cloud Market Share 2019: AWS vs Azure vs Google – Who’s Winning?

By on Oct 25, 2019

Cloud Market in 2019 and Predictions for 2022

Industry analyst firm Gartner predicts that the infrastructure-as-a-service (IaaS) market will grow by 27.5% in 2019 (a significant decrease from Gartner’s 2018 35.9% growth prediction) to reach $38.9 billion by the end of the year. Even with IaaS YoY growth predictions decreasing (from 35.9% to 27.5%), IaaS is still the fastest-growing market segment, and is expected to reach $76.6 billion by 2022.

The software-as-a-service (SaaS) industry is expected to grow by 18.5% to reach $94.86 billion by the end of 2019. According to the same Gartner report, SaaS is forecasted to grow to a whopping $143.7 billion by 2022.

Although much smaller than SaaS and IaaS, platform-as-a-service (PaaS) is expected to grow at a formidable 21.8% to reach $19 billion by the end of 2019. By 2022, Gartner expects PaaS to gain a total market size of $31.8 billion.

Public Cloud Market Share

In terms of revenue, Amazon Web Services dominates the public cloud market with revenue growing at 35% in Q3 of 2019. In its most recent earnings statement for Q3 of 2019, AWS reported revenues of $9 billion. While Microsoft Azure is gradually catching up to Amazon, it, along with Google Cloud Platform, lags behind AWS in market penetration and adoption.

According to a recent Cloud Security Alliance (CSA) report, Amazon Web Services is the most popular public cloud infrastructure platform, comprising 41.5% of application workloads in the public cloud. While Amazon has long been viewed as the dominant provider of public cloud infrastructure, Microsoft Azure is gaining ground quickly in application workload.

Azure currently holds 29.4% of the installed base, measured by application workloads. Google Cloud Platform trails with 3.0% of application workloads followed by IBM SoftLayer, Rackspace, and a long tail of providers that comprise another 20.7% of the market. The scope of long tail provider usage is surprising and may indicate the market is still at an early stage of maturity.

IaaS Adoption Trends: From on-premise data centers to cloud computing

The Future of Application Workloads…

Enterprises are gradually divesting from their data centers and moving applications workloads to the public cloud. According to the CSA survey report:

  • In 2016, 60.9% of applications workloads were still in enterprise data centers.
  • By the end of 2017, however, fewer than half (46.2%) will remain there.

This is, in part, due to new applications primarily being deployed in the cloud, and because enterprises plan to migrate 20.7% of their existing applications to the public cloud.

As expected, larger enterprises have the most custom applications deployed at their organizations. On average, companies with over 50,000 employees had 788 apps deployed, compared to 22 apps at companies with less than 1,000 employees.

What’s holding companies back from IaaS adoption?

Answer: Security concerns

You’ve probably guessed this correctly; despite the incredible progress cloud service providers like Amazon, Microsoft, and Google have made in the past few years around the security of their services, many enterprises continue to have reservations about IaaS adoption, primarily based on security concerns.

Perceived threats to running custom applications in IaaS (and how to avoid them):

  1. When asked about the greatest threats to applications running in the public cloud in the CSA survey report, the single most common response (66.5%) was sensitive data uploaded to the cloud. Some organizations have regulatory compliance and data residency requirements that can prevent users from uploading sensitive data to a cloud environment.
  2. The second most common perceived threat to running custom apps in IaaS was third-party account compromise (56.9%). With customers being at fault in the majority of breaches, organizations simply need to follow security best practices to alleviate their reservations about cloud adoption.

Recent data exposures

In the last month, we’ve seen several examples of companies that had exposed data due to simple misconfiguration of their IaaS environments, particularly leaving S3 buckets with sensitive data publicly accessible.  While this is a widespread concern, this type of exposure is easily avoidable, and you can find more on this is our recent blog here.

Despite security concerns, overall confidence is high

Security concerns may be the largest barrier to cloud adoption, but generally speaking, IT professionals view public cloud providers as being secure. A majority of respondents (62.9%) say the public cloud is as secure or more secure than their own data center.

This increasing confidence in cloud security could be one reason why enterprises have rapidly moved these applications out of the data center to the public cloud. Another reason why the majority of IT leaders are in favor of cloud adoption may be due to the sizable investments cloud providers made to their own security.

It may also be due to the fact that 3rd party security solutions, such as a CASB, have overcome the security gap between what an enterprise can achieve in their on-premises IT infrastructure and what they get from a cloud service provider.
