Oracle Cloud Infrastructure
Enterprise cloud with the industry's most generous always-free tier.
The verdict
Oracle Cloud Infrastructure (OCI) is Oracle's enterprise cloud platform, known for its Always Free compute and database resources, strong price-performance on bare metal, and Autonomous Database. It appeals to enterprises already running Oracle databases as well as cost-conscious developers.
The full picture
Oracle Cloud Infrastructure is worth attention for one reason above all others: its Always Free tier is the most generous in the industry by a wide margin. Four ARM-based Ampere cores, twenty-four gigabytes of memory, two hundred gigabytes of block storage, ten terabytes of monthly egress and a load balancer, free permanently, not for twelve months. That is enough to run a real production application, and a great many small projects do exactly that.
Beyond the free tier, OCI is a serious enterprise cloud built on a second-generation architecture with a flat, non-blocking network, bare metal instances, and RDMA cluster networking for high-performance computing. Oracle Autonomous Database is genuinely differentiated technology. Egress pricing is dramatically cheaper than AWS, Azure or Google Cloud, which for bandwidth-heavy workloads changes the arithmetic entirely.
The reservations are ecosystem and experience. Documentation and community are thinner than the big three, the console has its own conventions, Always Free capacity is sometimes unavailable in popular regions, and Oracle's commercial reputation makes some buyers wary. Technically, the platform is far better than its reputation.
What you get

Every hosting type it sells
| Product | From | What it is |
|---|---|---|

| Compute instances | Usage | ARM and x86 virtual machines plus bare metal. |
| Autonomous Database | Usage | Self-tuning, self-patching Oracle database with a free tier. |
| Object storage | Usage | S3-compatible storage with very low egress rates. |
| Kubernetes (OKE) | Usage | Managed Kubernetes with a free control plane. |
Plans & pricing
- 2 AMD Compute VMs
- Autonomous Database (2 instances)
- 10 GB Object Storage

What the price actually costs you
- The Always Free tier is permanent, not a 12-month trial — a genuine outlier.
- Egress is priced far below the other hyperscalers, often the deciding factor for media workloads.
- Paid compute is competitively priced, particularly ARM instances.
- Always Free capacity can be unavailable in popular regions; choosing a quieter home region helps.
Technical specification

| Architectures | ARM Ampere, AMD, Intel and bare metal instance shapes |
| Networking | Flat non-blocking network, RDMA cluster networking for HPC |
| Egress pricing | Substantially cheaper than AWS, Azure and Google Cloud |
| Database | Autonomous Database with self-tuning and self-patching |
| Regions | 48+ regions including sovereign and government clouds |
| Multi-cloud | Direct interconnects to Azure and Google Cloud |
| Compliance | FedRAMP, SOC, ISO 27001, PCI DSS, HIPAA and regional certifications |
| Support | Free basic support; paid tiers for production workloads |
| Uptime SLA | 99.95% with performance and manageability SLAs as well as availability |
Performance in practice
Strong, particularly on the ARM Ampere instances that also power the free tier — four Ampere cores is real compute, not a burstable fraction. The network architecture is flat and non-blocking, which gives consistent throughput between instances, and bare metal options remove the hypervisor entirely. The main practical constraint is Always Free capacity availability in busy regions, which can require patience or a different home region.

Moving a site in
Oracle provides migration tooling for databases and virtual machines, plus professional services for enterprise moves. For a small project, you deploy directly rather than migrating.
The trade-off
In its favour
- Most generous always-free compute tier among major clouds
- Competitive pricing on outbound data transfer
- Strong performance for database workloads
Worth knowing
- Smaller ecosystem and community than AWS/Azure/GCP
- Console can feel less polished
- Fewer third-party integrations
Who should look elsewhere
- Buyers who want the largest community and deepest third-party ecosystem
- Simple website hosting where a managed host is far easier
- Organisations with policy objections to Oracle as a vendor
- Teams that need the broadest managed service catalogue

Common questions
Is Oracle Cloud really free?
Oracle's Always Free tier includes select compute, storage and database resources that never expire, on top of a limited-time free trial credit.
Does OCI support Kubernetes?
Yes, Oracle Container Engine for Kubernetes (OKE) is a free-to-manage managed Kubernetes service on OCI.
The bottom line
Technically much better than its reputation, and the Always Free tier is the single best free offer in cloud computing — enough to run a genuine production application at no cost. Cheap egress makes it compelling for bandwidth-heavy workloads. Accept thinner documentation and a smaller community.
