IBM vs. Amazon: Which Cloud Infrastructure Stock Offers More Upside?

International Business Machines Corporation IBM and Amazon.com, Inc. AMZN are leading players in the global cloud computing industry. IBM offers cloud and data solutions that aid enterprises in digital transformation. In addition to hybrid cloud services, the company provides advanced information technology solutions, computer systems, quantum computing and supercomputing solutions, enterprise software, storage systems and microelectronics.

On the other hand, Amazon Web Services (“AWS”) is the world’s most comprehensive and widely adopted on-demand cloud computing platform, offering more than 200 fully featured services from data centers globally. Millions of customers, including the fastest-growing startups, largest enterprises and leading government agencies, are using AWS to lower costs, become more agile and innovate faster. It reportedly offers the widest variety of databases that are purpose-built for different types of applications to enable subscribers to choose the right tool for the job.

With a focus on hybrid cloud and AI (artificial intelligence), both IBM and Amazon are strategically positioned in the cloud infrastructure market and have the wherewithal to cater to the evolving demands of business enterprises. Let us delve a little deeper into the companies’ competitive dynamics to understand which of the two is relatively better placed in the industry.

The Case for IBM

IBM is poised to benefit from healthy demand trends for hybrid cloud and AI, which drive the Software and Consulting segments. The company’s growth is expected to be aided by analytics, cloud computing and security in the long term. IBM has extended its collaboration with NVIDIA Corporation NVDA to scale AI workloads and agentic AI applications. Per the latest agreement, IBM aims to launch a content-aware storage (CAS) capability for its hybrid cloud infrastructure offering (dubbed IBM Fusion) and expand its watsonx integrations with NVIDIA while introducing new IBM Consulting capabilities. 

The CAS capability will enable firms to extract the hidden meaning of unstructured data for inferencing to scale and enhance AI applications without compromising security. The integration of watsonx with NVIDIA Inference Microservices will offer firms greater accessibility to leading AI models across multiple cloud environments. IBM’s watsonx platform is likely to be the core technology platform for its AI capabilities. This enterprise-ready AI and data platform delivers the value of foundational models to the enterprise, enabling them to be more productive.

Despite solid hybrid cloud and AI traction, IBM is facing stiff competition from AWS and Microsoft Corporation’s MSFT Azure. Increasing pricing pressure is eroding margins, and profitability has trended down over the years, barring occasional spikes. The company’s ongoing, heavily time-consuming business model transition to the cloud is a challenging task. Weakness in its traditional business and foreign exchange volatility remain significant concerns.

The Case for Amazon

Amazon is the leading provider of cloud infrastructure as a service to enterprise customers. The expanding customer base of AWS, driven by its strengthening cloud offerings, will continue to aid Amazon's dominance in the global cloud space. Amazon’s strategic expansion of its Bedrock platform has positioned it as a frontrunner in the enterprise AI race. Amazon Bedrock has emerged as a game-changing, fully managed service that offers enterprises seamless access to high-performing foundation models from leading AI companies. The platform's recent developments, including automated reasoning checks and multi-agent collaboration capabilities, address critical challenges in AI adoption while opening new revenue streams for Amazon's cloud division.

The company is investing heavily in AI infrastructure, including the development of custom AI silicon like Trainium 2, which offers 30-40% better price performance than competing GPU-powered instances. Amazon aims to extend AWS’ AI and machine learning (ML) capabilities to facilitate improved decision-making. It intends to expand its global infrastructure for faster and more reliable service with low latency and maximum availability. From cloud-native applications and AI-driven solutions to edge computing and sustainability initiatives, AWS is likely to push the limits in the realm of cloud computing technology.

However, the substantial capital expenditure required for AI infrastructure expansion may weigh on margins in the coming quarters. In addition, while AWS' growth remains impressive, the company faces capacity constraints in AI services that could limit near-term growth potential. Moreover, AWS has historically been less open to hybrid cloud than rivals like Microsoft Azure, which integrates well with on-premise environments via tools like Azure Arc. Data localization laws and stricter regulatory requirements create friction for AWS' global expansion, while stringent government scrutiny in regions like the EU and China adds compliance complexity.
