Compare All Cloud Infrastructure Software 2026

Cloud infrastructure refers to the virtualized computing resources—servers, storage, networking, and databases—delivered on demand over the internet. Providers like AWS, Azure, and Google Cloud let businesses rent infrastructure instead of buying physical hardware, paying only for what they use.

Cloud infrastructure costs vary widely based on usage. A basic virtual machine starts at $2.50-$5/month (Vultr, DigitalOcean), while production workloads typically cost $50-$500/month. Enterprise deployments on AWS, Azure, or GCP can run $10,000-$100,000+/month depending on compute, storage, and data transfer needs.

For simple workloads, independent providers like Vultr ($2.50/mo), DigitalOcean ($4/mo), and Linode ($5/mo) are cheapest. Among hyperscalers, pricing is comparable—AWS, Azure, and GCP all offer similar rates for equivalent compute, but each offers different discount structures (Reserved Instances, Committed Use, Spot pricing) that can reduce costs 30-70%.

AWS has the largest service catalog and market share (31%). Azure integrates best with Microsoft tools and is preferred by enterprises. Google Cloud excels at data analytics, AI/ML, and Kubernetes. Choose based on your existing tech stack, specific services needed, and team expertise rather than price alone.

Common hidden costs include data egress fees ($0.01-$0.09/GB for transferring data out), cross-region transfer charges, premium support plans ($29-$15,000/month), load balancer fees ($16-$25/month each), public IP charges, and logging/monitoring costs. Data egress is often the biggest surprise on cloud bills.

Yes, all three hyperscalers offer free tiers. AWS Free Tier includes 750 hours/month of t2.micro for 12 months. Google Cloud offers $300 in credits for 90 days plus always-free resources. Azure provides $200 in credits for 30 days plus 12 months of free services. DigitalOcean offers $200 in credits for 60 days.

Key strategies include: using reserved instances or committed use discounts (save 30-60%), right-sizing underutilized instances, using spot/preemptible instances for fault-tolerant workloads (save 60-90%), implementing auto-scaling, choosing appropriate storage tiers, and monitoring with tools like AWS Cost Explorer or Google Cloud's cost management tools.

IaaS (Infrastructure as a Service) provides raw compute, storage, and networking—you manage everything above the hardware. PaaS (Platform as a Service) adds managed runtimes and databases. SaaS (Software as a Service) delivers complete applications. Cloud infrastructure providers primarily offer IaaS and PaaS, with AWS, Azure, and GCP offering all three.

Hyperscalers (AWS, Azure, GCP) are best for complex architectures needing managed services like serverless, AI/ML, or global CDNs. Independent providers (DigitalOcean, Linode, Vultr) are better for straightforward workloads—VMs, databases, object storage—at 2-5x lower cost with simpler pricing and no surprise bills.

Cloud is typically cheaper for variable or growing workloads and eliminates upfront hardware costs. On-premises can be 30-50% cheaper for stable, predictable workloads over 3-5 years when factoring in hardware depreciation. Most organizations use a hybrid approach, keeping steady-state workloads on-premises and bursting to cloud.
