Why Cloud Computing Keeps Growing
Cloud computing has become a foundational layer of modern business infrastructure. Companies of all sizes are migrating workloads to the cloud to reduce capital expenditure on hardware, gain on-demand scalability, and accelerate software delivery. This shift benefits a broad ecosystem: data center operators, semiconductor manufacturers, telecommunications providers, and software vendors all stand to gain as adoption expands.
A 2016 survey by growth equity and venture capital firm North Bridge and research firm Wikibon projected public cloud spending would grow from approximately $75 billion in 2015 to over $500 billion by 2026, implying a compound annual growth rate of around 19 percent. While those projections are now dated, the directional trend—sustained, rapid growth—has broadly held.
“As the cloud ecosystem matures, users are turning to a broad spectrum of technology and integration companies to help unlock the potential of the cloud.”
Stuart Miniman, Wikibon analyst (2016)
Understanding the Three Cloud Models
Before examining individual companies, it helps to understand the three primary cloud deployment models, since each creates different opportunities and risks for vendors and investors.
Public Cloud
In the public cloud, infrastructure is owned and operated by a third-party provider and delivered over the public internet. Customers pay for what they consume rather than owning servers outright. This model suits workloads where security requirements are standard and operational simplicity matters most. It is the fastest-growing segment and the one that most directly benefits hyperscale providers such as Amazon, Microsoft, and Google.
Private Cloud
Private clouds use dedicated infrastructure, typically hosted in a company-owned or co-location data center and connected via private networks. Regulated industries such as banking and healthcare often prefer private clouds because they offer greater control over data residency and security posture.
Hybrid Cloud
Hybrid cloud combines public and private resources, allowing organizations to keep sensitive data behind their own firewall while bursting to public cloud capacity for less sensitive or compute-intensive workloads. The North Bridge/Wikibon survey found that hybrid was the predominant strategy at the time, with 47 percent of respondents using it, compared with 30 percent for public and 23 percent for private. Hybrid architectures are especially common in financial services and healthcare, where compliance requirements restrict where certain data can reside.
Key Segments of the Cloud Ecosystem
The cloud market is not monolithic. Growth, margin, and competitive dynamics differ significantly across segments.
Software (SaaS and PaaS): Highest Long-Term Value Potential
Software-as-a-service and platform-as-a-service companies tend to command the highest valuations and margins in the cloud ecosystem. Because software is infinitely replicable and benefits from network effects, successful cloud software vendors can scale revenue without proportional increases in cost. Analysts who follow the sector have long argued that software—not infrastructure—is where the most durable value will be created.
Data Centers and Telecom: Infrastructure Growth, but Eventual Commoditization
Data center operators and telecommunications companies provide the physical backbone of cloud services. Demand for co-location, interconnection, and private networking continues to rise alongside cloud adoption. However, as multiple providers compete on similar capabilities, pricing for raw connectivity and compute capacity tends to compress over time—a pattern already visible in public cloud storage and compute pricing.
Hardware: Consolidation Pressure
Cloud architectures allow hyperscale operators to extract more work from fewer, more efficient servers. This reduces total unit volumes for traditional server hardware vendors. The hyperscalers also increasingly design custom silicon—a trend that has accelerated significantly since 2017—which further pressures incumbent chip and server vendors. Consolidation among hardware makers is an expected consequence.
Major Players in the Cloud Space
The following companies were identified by analysts at the time of the original article as significant participants across different segments of the cloud ecosystem. Their relative positions have evolved since 2017.
Amazon (AMZN) — Amazon Web Services
Amazon Web Services has consistently held the largest share of the public cloud infrastructure market. AWS pioneered the infrastructure-as-a-service model and continues to offer the broadest portfolio of cloud services. Its early-mover advantage created deep customer dependencies through proprietary managed services, making migration to competing platforms costly for established customers.
Microsoft (MSFT) — Azure and Microsoft 365
Microsoft has been one of the most successful examples of a legacy software giant pivoting to cloud-native delivery. Azure competes directly with AWS for enterprise infrastructure workloads, while Microsoft 365 (formerly Office 365) demonstrated how subscription-based cloud software can replace perpetual license revenue. The transition initially involved replacing boxed-software revenue with subscription revenue, but the recurring model has since driven significant margin expansion.
Salesforce (CRM)
Salesforce is one of the original SaaS companies and remains a benchmark for cloud-delivered enterprise software. Its CRM platform gives businesses cloud-based tools to manage customer relationships, sales pipelines, and marketing automation. As more companies move application workloads to the cloud, platforms that aggregate and analyze customer data become more valuable.
Alphabet / Google (GOOGL) — Google Cloud
Google Cloud Platform has grown substantially since 2017 and is now widely recognized as the third major hyperscale public cloud provider alongside AWS and Azure. Google brings particular strengths in data analytics, machine learning infrastructure, and Kubernetes—the container orchestration system it originally developed.
Equinix (EQIX)
Equinix operates a global network of co-location data centers and interconnection hubs. Its value proposition lies in proximity: customers can place their infrastructure in the same facilities as cloud on-ramps, financial exchanges, and network carriers, reducing latency and enabling private connectivity to public cloud providers. This positioning suits hybrid cloud architectures particularly well.
Telecom Providers — CenturyLink (now Lumen), AT&T, Verizon
Telecommunications companies own the fiber and network infrastructure that carries cloud traffic. They are well positioned to offer managed networking services, private cloud connectivity, and edge computing capabilities—especially as latency-sensitive workloads push compute closer to end users. However, telcos face ongoing pressure from hyperscalers expanding their own networking capabilities.
Intel (INTC)
Intel historically dominated the data center CPU market. However, since 2017 the competitive landscape has shifted materially: AMD has gained significant server market share with its EPYC processors, Arm-based server chips from Ampere and others have entered the market, and hyperscalers including Amazon, Google, and Microsoft have designed proprietary silicon to reduce their dependence on Intel. Intel remains a major supplier but faces more competition than at the time of the original article.
Nvidia (NVDA)
Nvidia’s GPU accelerators have become central to cloud workloads involving artificial intelligence, machine learning training, and high-performance computing. As CPU clock speed improvements slowed, GPUs and other accelerators took on an expanding share of data center compute. The explosion of large language model training and AI inference workloads since 2022 has made Nvidia one of the most scrutinized companies in the technology sector.
What This Means for DevOps and Engineering Teams
Understanding the cloud ecosystem beyond your immediate provider has practical implications for infrastructure decisions:
- Hybrid architectures require deliberate design. Connecting private infrastructure to public cloud services introduces network, security, and operational complexity that must be planned from the start, not retrofitted.
- Vendor concentration is a risk. Deep reliance on proprietary managed services from a single hyperscaler increases switching costs. Teams should evaluate where multi-cloud or cloud-agnostic tooling reduces lock-in without sacrificing operational efficiency.
- Hardware trends affect workload placement. The availability of GPU instances, Arm-based compute, and specialized accelerators from cloud providers means workload-to-hardware matching is increasingly important for both performance and cost.
- Software spending dominates long-term value. The pattern observed in this analysis—that software captures more durable margin than infrastructure—is also visible in cloud bills: managed services and SaaS tools often exceed raw compute costs for mature engineering organizations.
Summary
The cloud computing ecosystem spans public, private, and hybrid deployment models, with growth opportunities distributed unevenly across software, data center infrastructure, telecommunications, and hardware. Software and platform services tend to offer the strongest long-term margin and innovation potential. Infrastructure and connectivity services will grow but face commoditization pressure over time. Hardware vendors face consolidation as cloud efficiency reduces unit volumes, even as demand for specialized accelerators—particularly GPUs—has become a major growth driver.
For DevOps engineers and architects, understanding these dynamics helps inform decisions about vendor selection, workload placement, and long-term infrastructure strategy.
