Choosing between AWS and GCP in 2026 is less about which cloud is "better" and more about matching the platform to your team's actual workload mix. Both run globally, both have mature Kubernetes and serverless layers, and both will happily take your budget. The differences that matter are narrower — but they're real.
What changed in 2026
- GCP Vertex AI consolidated everything — AutoML, custom training, model endpoints, and the Gemini API now live in one product surface. The friction for ML teams dropped significantly.
- AWS Bedrock expanded model coverage — Anthropic Claude, Meta Llama, Mistral, and Cohere are all accessible through a single SDK, making AWS the safer bet for teams that want model portability without juggling API keys.
- GCP Cloud Run gen 2 is production-grade — cold starts under 200 ms and up to 32 GB RAM per instance, which puts it on par with AWS Lambda for most serverless patterns.
- AWS cost tooling matured — Cost Anomaly Detection and per-resource tagging are robust enough that the "AWS is expensive and hard to track" complaint has faded for well-architected accounts.
- Spot/Preemptible instance reliability improved on both — interruption rates dropped; batch and training workloads can safely rely on them.

Pricing model differences
AWS pricing requires active work to optimise:
- On-demand is the baseline — expensive at scale.
- Savings Plans (1 or 3 year, compute or service-specific) give 30–60% off.
- Spot Instances give 60–80% off but can be interrupted with a 2-minute notice.
GCP pricing has automatic discounts built in:
- Sustained-use discounts apply automatically after 25% monthly usage — no commitment required.
- Committed-use discounts (1 or 3 year) stack on top for another 20–30%.
- BigQuery charges on bytes scanned, not instance uptime — this alone can make GCP cheaper for analytics teams.
Example: 10 TB/month analytics query workload
AWS Redshift (ra3.4xlarge, 2 nodes, on-demand): ~$3,200/mo
GCP BigQuery (on-demand scan pricing): ~$500–900/mo depending on query patterns
GCP BigQuery (flat-rate slots, 500 slots): ~$2,000/mo with predictable cost
How to pick
- Primary workload is data warehousing or batch ML? → GCP. BigQuery and Vertex AI are genuinely the better products here.
- Primary workload is SaaS/web/mobile with mixed services? → AWS. The ecosystem, hiring pool, and third-party integrations are unmatched.
- Team already deep in Google Workspace and GKE? → GCP. Identity and IAM integration is smoother.
- Need the widest possible AI model selection via a managed API? → AWS Bedrock. GCP is Gemini-first.
- Regulated industry needing FedRAMP/HIPAA on the broadest set of services? → AWS still leads on compliance coverage.
Deployment example: GKE Autopilot vs EKS
# GKE Autopilot cluster — no node management, GCP handles scaling
gcloud container clusters create-auto my-cluster \
--region us-central1 \
--release-channel regular
# EKS with managed node group
eksctl create cluster \
--name my-cluster \
--region us-east-1 \
--nodegroup-name standard \
--node-type m6i.large \
--nodes 3
GKE Autopilot has no node management overhead; EKS gives finer control over instance types and placement groups.
Common mistakes
Lifting-and-shifting to on-demand, then optimising later. "Later" never comes. Apply Savings Plans or committed-use discounts from month two.
Treating S3 and Cloud Storage as interchangeable in Terraform. Bucket policies, object versioning syntax, and lifecycle rule formats differ. Abstract them with a module from day one.
Using GCP for everything when your ML workload is inference-only. Vertex AI excels at training. For inference at scale, AWS Bedrock or a dedicated inference endpoint can be cheaper.
Ignoring egress costs. Both clouds charge for data leaving the region. Cross-cloud egress is particularly expensive — design around it.
What to skip
- Multi-cloud for redundancy — run multi-region on one cloud instead. Multi-cloud adds operational complexity that rarely justifies the theoretical availability gain.
- GCP for heavy Windows/.NET workloads — AWS has deeper Windows Server and SQL Server licensing integration.
- Custom VM flavours before benchmarking — start with general-purpose (m6i on AWS, n2 on GCP), profile, then move to compute- or memory-optimised.
FAQ
Can I run Terraform on both without rewriting everything?
Mostly yes — Terraform providers for both are mature, but resource schemas differ. Use workspace-level provider aliasing and keep cloud-specific resources in separate modules.
Which has better Kubernetes support?
GKE has historically led on GKE Autopilot and faster Kubernetes version rollouts. EKS caught up significantly with managed nodes and add-on management, but GKE Autopilot is still simpler to operate day-to-day.
Is GCP cheaper overall?
For analytics and ML training, often yes. For general compute and web serving, the delta is small — under 10% after equivalent discount tiers.
Which cloud do startups prefer in 2026?
AWS still dominates startup adoption (~60% of seed-stage companies) due to credits programs and ecosystem familiarity. GCP has grown share among data-heavy and ML-native startups.
