Ten years ago, moving to the cloud was a competitive advantage. Today, it’s a bare necessity. According to Gartner’s 2025 forecast, global end-user spending on public cloud services will reach $723.4 billion this year, up from $595.7 billion in 2024. That’s a 21.5% jump, and shows just how much we are entering an era where businesses are fully committed. It’s becoming rare to find companies that host large datasets independently.
Cloud computing refers to the use of computing resources (servers, storage, databases, networking, software) over the internet on a pay-as-you-go basis. Instead of buying and maintaining physical data centers, you rent what you need from providers like AWS, Microsoft Azure, or Google Cloud. One way to think of it is the difference between having a generator at home versus plugging into the electrical grid. You get the same electricity, but without the infrastructure headaches.
The biggest shift in cloud computing is the transition from capital expenditure to operating expenditure. You pay only for what you use.
Even with a traffic spike, cloud computing can spin up new servers in minutes. When demand drops, it facilitates the ability to scale back and be cost-efficient. Basically, it delivers great flexibility.
Helps a lot with remote work and distributed teams; everyone can access the same information anywhere, not to mention apps on the cloud. It’s one of the biggest reasons hybrid/remote work now works so well.
While many have security concerns with cloud computing, around 94% of businesses report improved security post-migration, thanks to the cybersecurity suites that cloud companies implement, which most companies can’t match in-house.
Despite these improvements, the cloud’s shared responsibility model means organizations need to be cautious with their own access. Misconfiguration is a leading breach cause.
Cloud-hosted data means analytics tools process information immediately. BI dashboards update in real-time, letting executives spot trends within hours, not weeks.
IaaS is a kind of ‘minimal’ cloud; it provides just the raw storage and pieces you need to use their compute. You manage it all from the OS to apps. AWS EC2 and Azure Virtual Machines lead, and it’s the fastest-growing segment.
PaaS is considered a middle-ground approach. A platform that gives all the basics to use, but leaves the majority to the developers. Google App Engine and AWS Elastic Beanstalk are key examples, but this is the most uncommon type.
Currently, the king of the cloud space is what most people are familiar with: everything from Salesforce, Microsoft 365, to Slack. Gartner forecasts nearly $300 billion in SaaS spending in 2025, the largest segment.
Healthcare utilizes the cloud for patient records and HIPAA compliance. Financial services run trading algorithms on scalable infrastructure. Walmart uses a hybrid cloud for real-time inventory. Siemens connects factory IoT sensors to the cloud via MindSphere. Across sectors, cloud unlocks capabilities once reserved for the largest enterprises.
Security concerns are usually at the top of any list, but mostly come from misunderstanding how current shared responsibility systems work with leading cloud providers. The other major concern is that 27% of cloud spend is being wasted, as mentioned. Plus, legacy compatibility can really slow things down.
Look at your workload first, not the vendors. Hybrid is currently the most popular, with Flexera citing that about 70% use some kind of hybrid approach. Basically, you want to match your workload to the right environment.
The clear frontrunner here is AI, which has been accelerating cloud use by a wide margin for the last few years. Even from 2024 to 2025, we saw an increase to 72% of all orgs using GenAI cloud services, up from 47% YoY. Industry-specific platforms and FinOps are also seeing greater use.
Most businesses are involved in cloud computing in some capacity. The question is how much and how to deal with it. Usage optimization is the biggest trend here, as leveraging it for an efficient cost is the greatest strategic advantage.
Cloud computing is compute resources that are accessed on demand over the internet, used to reduce infrastructure costs, provide flexibility, and enable access to technology and apps that wouldn’t be available without a high upfront cost.
It moves spending costs from capital infrastructure costs to operational expenses. The typical migration to cloud computing cuts TCO by 30-40%.
It allows a business to provision new servers and compute resources in minutes, without needing to build up the infrastructure themselves. It’s automatic scaling without the need for manual capacity planning.
Yes. Major providers have massively invested in their security, which most smaller businesses can’t do. For 94% of businesses that have migrated, this has meant security improvements post-migration.
Cloud applications are accessible from anywhere with the internet, enabling teams to share tools and data regardless of location.
IaaS (raw infrastructure), PaaS (managed platform for deploying apps), and SaaS (ready-to-use software via browser). Most enterprises use all three for different aspects of their business.
We are seeing the most benefits to healthcare, retail, financial services, and manufacturing, among others.
Security concerns stand out first, but then ballooning costs and legacy compatibility are close seconds. Spend management tends to be a concern for all cloud users.
It depends on workload, regulatory constraints, and capabilities. Hybrid approaches are generally the right move; approximately 70% of orgs use a bit of both.
AI-powered services are certainly the biggest players at the moment, but FinOps practices are evolving for better cost management.
