The State of the Cloud Computing Market

For many enterprises and consumers, the cloud has been an efficient, cost-effective alternative to maintaining on-site network infrastructure. In 2023, cloud computing continued to be a rapidly growing sector. The market can be segmented based on service, deployment mode, organization size and region, with North America being the largest geographic segment, followed by Europe and Asia Pacific.

AWS, Microsoft, and Google Cloud collectively hold a 66 percent share of the worldwide cloud market, as they compete for leadership in this space. Alibaba Cloud, IBM Cloud, Salesforce, Oracle Cloud, SAP Cloud Platform, and VMware Cloud are also key companies in the cloud computing market.

The third quarter of 2023 saw worldwide spending on cloud infrastructure services (i.e. cloud services that provide infrastructure) surpass $68 billion, with an 18 percent growth rate from the previous year, marking the fifth consecutive quarter of substantial growth.

Investments in generative AI technology by cloud providers are cited as a key factor in driving spending on cloud services, which is likely to keep cloud growth growing in the coming years. Tech giants are pouring billions into cloud capacity to support AI initiatives, with significant capital spending directed towards generative AI systems that require extensive computing power and data crunching. For example, Amazon, Microsoft, and Google have increased their investment in computing infrastructure, with a combined $32bn in the third quarter of 2023, almost 50 percent more than the same period in 2020.

The global cloud computing market size is valued at over $500 billion in 2023, with predictions that it will surpass $1 trillion by 2028 and $1.6 trillion by 2030. SaaS dominates the public cloud services market, and cloud-based workloads make up 75% of workloads in 1 out of 5 organizations.

Key Players in the Cloud Computing Ecosystem

Various entities play distinct roles in the cloud computing ecosystem as follows:

1. Cloud Service Providers (CSPs): These are the backbone of the cloud ecosystem, offering a range of services that can be categorized into three main types:

   • Infrastructure as a Service (IaaS): Provides fundamental compute, network, and storage resources to consumers on-demand, over the internet, and on a pay-as-you-go basis. Examples include Amazon EC2, Google Compute Engine and Microsoft Azure Virtual Machines.

   • Platform as a Service (PaaS): Offers a development and deployment environment in the cloud, including tools to build, test, and deploy applications. Examples include Google App Engine, AWS Elastic Beanstalk and Azure App Services.

   • Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis. Examples include Salesforce, Microsoft Office 365 and Google Workspace.

2. Hardware and Infrastructure Vendors: Companies like Dell, HP, IBM, and Cisco provide the physical servers, storage systems and networking equipment that power data centres. Companies like NVIDIA and AMD supply GPUs that are critical for high-performance computing and compute-intensive tasks such as AI, machine learning and big data analytics in the cloud. These companies manufacture and supply the physical components that form the data centres of CSPs. Several prominent cloud service providers such as AWS, Microsoft Azure, Google Cloud Platform, IBM Cloud and Alibaba Cloud use NVIDIA chips to enhance their cloud computing offerings.

3. Software Vendors: These are companies that develop the operating systems, management tools, and platforms that run on cloud infrastructure. Examples include Red Hat (now part of IBM), VMware and Oracle.

4. Telecommunications Providers: Telecom providers offer the network connectivity required for cloud services to be accessible over the internet. They play a crucial role in ensuring high-speed and reliable access to cloud resources. Examples include AT&T, Verizon, BT and Deutsche Telekom.

5. Managed Service Providers (MSPs): MSPs offer managed cloud services, handling the deployment, management, and maintenance of cloud infrastructure for their clients and providing additional services such as monitoring, performance reporting, and security management.  Examples include DXC Technology, IBM Cloud Managed Services and Accenture Cloud Services.

6. Cloud Consumers: Enterprises, governmental organisations, small and medium-sized businesses, startups and individual users who utilize cloud services for various purposes, such as hosting websites, storing data or running enterprise applications.

7. Cloud Security Vendors: Companies that specialize in providing security solutions for the cloud, such as firewalls, intrusion detection systems and encryption services. Examples include Palo Alto Networks, McAfee, and Symantec.

8. Regulatory Bodies: These organizations set the rules and standards that govern the cloud industry.

   • In the UK, cloud computing services are subject to the rules set by the Information Commissioner's Office, which enforces data protection laws such as the UK General Data Protection Regulation and the Data Protection Act 2018. Additionally, the Financial Conduct Authority may also have oversight if the cloud services are used by financial institutions.

   • In the European Union, the General Data Protection Regulation is the primary regulatory framework governing data protection and privacy, which affects cloud service providers operating within EU member states. The European Data Protection Board provides guidance on GDPR compliance. Moreover, the EU's Cybersecurity Act and the Network and Information Systems Directive also play roles in setting standards for cybersecurity across the EU, which includes cloud computing services. Around mid-2025, new rules under the EU Data Act will also come into effect which will introduce switching requirements for CSPs.

Future Trends

As has been the case over the past decade, cloud adoption and proliferation will continue. Cloud customers and suppliers will continue to develop their understanding of related risks, based on practical experiences of what can go wrong. Similarly, regulators' expectations (including in the financial services sector) of companies involved will increase. The EU Data Act will require cloud service providers to update their contracts in relation to supporting their customers in switching between different services (including on the costs that they can charge for that support).

Generative AI technology has been a major driver of cloud services in the last few years. Google, Microsoft and Google are spending billions on cloud infrastructure to support AI projects, with a large part of the capital going towards generative AI systems that need significant computing power. 

Looking ahead, the cloud computing ecosystem is set to become even more diverse and integrated. Edge computing, which brings computation closer to the data source, is emerging as a new frontier. Hybrid and multi-cloud strategies are becoming the norm, as organisations seek to optimize performance and reduce cost for their cloud environments.
