Amazon Web Services (AWS)

Pros

• The service catalogue is unusually broad, with over 200 services across 38 regions, so most infrastructure needs can be met on one platform.
• EC2 has a 99.99% region-level SLA with credits of up to 100%, and instances unavailable for more than six minutes in an hour are not billed for that hour.
• The free plan gives up to $200 in credits, and more than 30 always-free services let new teams experiment at low cost.
• Support scales from a $29 minimum up to dedicated Enterprise and Unified Operations tiers for mission-critical workloads.
• G2 rates it 4.4 across more than 17,000 reviews, and reviewers praise its scalability and global reach.

Cons

• Reviewers widely cite a steep learning curve across the console and services.
• Usage pricing is complex and can produce unexpected bills unless spend is monitored closely.
• Paid support is billed as a percentage of total AWS spend, so support costs rise with usage.
• A July 2025 billing console bug showed customers estimated charges in the billions, which hurt trust in its cost tooling.

Modal

Pros

• GPUs from the T4 up to the B300 are available without quota requests or reservations, and workloads can burst to thousands of containers.
• Per-second billing and scale-to-zero mean idle bursty inference workloads cost nothing.
• Python developers define infrastructure in code and deploy with a single CLI command, with no Kubernetes or Dockerfiles needed.
• The free Starter plan includes $30 a month of compute, and startup and academic credit programs are available.
• Sandboxes support large numbers of concurrent isolated environments for AI agents and untrusted code.

Cons

• Always-on or steady workloads can cost more than reserved GPU rentals from providers such as RunPod or Lambda.
• Containers stay billable for 60 seconds after the last request by default, and keep-warm settings are a common source of bill surprises.
• Region pinning raises prices by 1.15 to 1.75 times, and non-preemptible execution by 3 times.
• SSO, audit logs, and HIPAA support are limited to the custom-priced Enterprise plan.
• Credits from AWS, GCP, or Azure cannot be applied to Modal usage.
