An OCI vs AWS pricing comparison should be done on negotiated rates, never on list. List comparisons exaggerate OCI's pricing advantage; enterprise AWS Reserved Instance and Savings Plan rates close most of the headline gap. What remains structurally cheaper on OCI: network egress, Oracle Database via BYOL with the 2:1 multiplier, and the Support Rewards programme that converts OCI spend into Oracle support credits. This is a buyer-side, service-by-service breakdown — list vs negotiated, and where to push back on each vendor's claim.
OCI and AWS sell capacity through fundamentally different commercial constructs. Understanding both is prerequisite to any meaningful comparison.
OCI Universal Credits is a prepaid commit, typically 1, 2, or 4 years, that draws down against any OCI service. Discount tiers escalate with commit size — typical enterprise discounts on a $500K-plus annual spend run 25 to 45 percent off list. Universal Credits do not expire monthly; unused credits at the end of a term are forfeited. The Support Rewards programme converts 25 percent (33 percent for ULA customers) of qualifying credits spend into Oracle technology support invoice credits.
AWS Savings Plans and Reserved Instances are the equivalent commitments. Compute Savings Plans commit to a $/hour of compute spend for 1 or 3 years across instance families and regions, discounting 30 to 72 percent against on-demand. EC2 Instance Savings Plans commit to a specific instance family / region, discounting up to 72 percent. Reserved Instances are the older model, family-and-region specific, up to 75 percent discount on a 3-year all-upfront commit.
The first negotiation move on AWS is to dial up the Savings Plan coverage and term to 3-year all-upfront where the workload is stable. The first negotiation move on OCI is to size the Universal Credits commit aggressively enough to unlock the higher discount tier and the Support Rewards multiplier.
| Shape | OCI (list) | AWS equivalent (on-demand) | AWS (3-yr Savings Plan) |
|---|---|---|---|
| 4 vCPU / 8 GB (general) | $0.087/hr (VM.Standard.E5.Flex) | $0.1632/hr (c7i.xlarge) | ~$0.054/hr |
| 8 vCPU / 32 GB (mem-optimised) | $0.262/hr (VM.Optimized3.Flex) | $0.4032/hr (m7i.2xlarge) | ~$0.133/hr |
| 16 vCPU / 64 GB | $0.523/hr | $0.8064/hr (m7i.4xlarge) | ~$0.267/hr |
| 32 vCPU / 128 GB | $1.046/hr | $1.6128/hr | ~$0.533/hr |
| ARM 4 vCPU / 24 GB | $0.040/hr (Ampere A1 Flex) | $0.0816/hr (c7g.xlarge) | ~$0.027/hr |
On list, OCI is 35 to 50 percent below AWS for x86 shapes and frequently 50 percent or more below AWS on ARM. On AWS 3-year Savings Plans at all-upfront, AWS comes within 10 to 25 percent of OCI list — and below OCI list on some shapes. Enterprise OCI Universal Credits discounts (25 to 45 percent off OCI list) restore OCI's compute lead.
The right comparison for any large workload is: AWS 3-year Savings Plan rate vs OCI Universal Credits negotiated rate. Doing the comparison on AWS on-demand vs OCI list overstates OCI's advantage by 40 to 60 percent.
| Service | OCI | AWS |
|---|---|---|
| Oracle Database (managed) | Base Database Service, Autonomous Database, Exadata DB Service | RDS for Oracle (License Included or BYOL) |
| PostgreSQL (managed) | OCI PostgreSQL ~$0.171/OCPU-hour | Aurora Postgres / RDS Postgres |
| MySQL (managed) | MySQL HeatWave | RDS MySQL / Aurora MySQL |
| NoSQL (key-value) | OCI NoSQL | DynamoDB |
| Data warehouse | Autonomous Data Warehouse | Redshift |
| Vector / search | 23ai Vector Search | OpenSearch, Aurora pgvector, Bedrock KB |
For Oracle Database, the OCI advantage is structural. Autonomous Database charges on ECPUs (and historically OCPUs) with built-in licence inclusion or BYOL multipliers. Exadata Database Service supports BYOL with the 2:1 OCI vCPU-to-Processor licence multiplier — half the licence count compared to deploying the same Oracle Database on AWS EC2 with the 1:1 conversion.
For non-Oracle databases, AWS has a deeper portfolio. Aurora Postgres, DynamoDB, and Redshift are mature services with operational ecosystems that OCI's equivalents do not yet match. The gap is narrower for new services (HeatWave is a credible MySQL competitor, OCI PostgreSQL is improving) but real.
| Storage type | OCI (list) | AWS (on-demand) |
|---|---|---|
| Block (general SSD) | $0.0255/GB-month + free 10 VPUs/GB | $0.080/GB-month (gp3) |
| Block (high IOPS) | $0.0255 + paid VPUs | $0.125/GB-month (io2) + per-IOPS |
| File (NFS) | $0.255/GB-month (File Storage) | $0.30/GB-month (EFS Standard) |
| Object storage (Standard) | $0.0255/GB-month | $0.023/GB-month (S3 Standard) |
| Object (Infrequent Access) | $0.010/GB-month | $0.0125/GB-month (S3 IA) |
| Object (Archive) | $0.0026/GB-month | $0.0036/GB-month (Glacier Deep Archive) |
| Egress (per GB) | 10 TB/region/month FREE, then $0.0085 | $0.09 (after first 100 GB/account/month) |
OCI block storage list is structurally cheaper than AWS gp3. Object storage list is within 10 to 20 percent — close enough that egress dominates the comparison. Cold-tier storage (Archive) favours AWS marginally on list. Across negotiated rates, the storage comparison narrows but OCI retains a list advantage on block.
Network egress is the most consistent commercial argument OCI has against AWS. The list rate gap is roughly 10x: AWS charges $0.09 per GB after the first 100 GB per month per account (with regional variation); OCI gives 10 TB per region per month free, then $0.0085 per GB. For workloads with substantial egress — content delivery, video streaming, backup and DR, multi-cloud replication, large data movement — the egress line alone can flip the TCO comparison.
Egress reductions on AWS through negotiated agreements are real but rarely match the OCI free-tier-plus-low-list combination. AWS's recent egress-allowance changes for customers leaving AWS slightly reduced the friction of multi-cloud egress in some categories, but for steady-state production egress the 10x gap persists.
For organisations evaluating multi-cloud disaster recovery, cross-cloud replication, or large media estates, egress economics frequently make OCI the destination cloud for egress-heavy services and AWS the source cloud — a deliberate split that exploits OCI's structural egress advantage.
For Oracle Database workloads, two OCI-specific commercial mechanisms determine the comparison:
The implication: for workloads where Oracle Database is a substantial portion of the total compute estate, OCI is structurally cheaper than AWS for the Oracle portion, frequently by 40 to 65 percent across compute plus licence plus support combined.
The trap: organisations sometimes interpret "OCI is cheaper for Oracle Database" as "OCI is cheaper across the board." For non-Oracle workloads, AWS is frequently cheaper on negotiated rates, particularly for serverless, container, and managed-service-heavy estates. The right answer is often a multi-cloud split that exploits both economics.
AWS has roughly 200+ services and a substantially deeper ecosystem of third-party integrations than OCI's roughly 100 services. The gap matters most in:
For organisations whose value is in the depth of cloud-native architecture (event-driven serverless, dozens of managed services composed into application platforms), AWS is the destination cloud. For organisations whose value is in running Oracle workloads with maximum commercial efficiency, OCI is. Most enterprises end up running both.
Scenario: A 250-employee software organisation lifts an on-premise Oracle Database EE estate (40 cores, with Partitioning, Advanced Compression, Diagnostics) plus surrounding application infrastructure (60 mid-sized x86 cores, 80 TB block storage, 12 TB object storage, projected 8 TB/month outbound egress) to the cloud. Annual on-premise Oracle support today: $440K. Compare 5-year TCO on OCI Universal Credits vs AWS with negotiated 3-year Savings Plans.
| Cost component (5-year) | OCI (negotiated) | AWS (3-yr SP negotiated) |
|---|---|---|
| Oracle Database compute (BYOL) | $280K | $540K (1:1 multiplier hurts) |
| Application compute (60 cores) | $520K | $610K |
| Block storage (80 TB) | $95K | $262K |
| Object storage (12 TB) | $15K | $14K |
| Egress (8 TB/month outbound) | $0 (under 10 TB free tier) | $430K |
| Managed database services | $120K | $140K |
| Networking / load balancers / WAF | $58K | $72K |
| Oracle support (5 yrs, pre-Support Rewards) | $2.20M | $2.20M |
| Support Rewards offset (25% on $1.0M qualifying) | -$255K credit applied | n/a |
| 5-year TCO | $3.03M | $4.27M |
Net: OCI lands $1.24M cheaper over five years, of which roughly $430K is egress and $255K is Support Rewards. Strip out the Oracle Database workload and the egress, and AWS frequently wins for the residual application-tier compute. The buyer-side answer is rarely "all-in on one cloud." To model the same comparison against your own Oracle processor count, options stack, and BYOL position, use the free Oracle 5-Year TCO Calculator (On-Prem vs OCI vs AWS) — it bakes in the Authorised Cloud Environments multiplier, Support Rewards offset, and the 5-year escalator path.
Three negotiation moves we use in every cloud sourcing engagement:
The least productive negotiation is "all-in on OCI" — Oracle's account team will treat the eliminated competitive pressure as licence to push aggressive renewal terms within the next 24 months. Multi-cloud, even at small scale on the non-primary cloud, preserves negotiation leverage.
A European media group ran a 60-core Oracle Database EE estate with Partitioning, Advanced Compression, Diagnostics, and a substantial broadcast infrastructure with high egress volumes. Initial AWS-only quote came to $4.8M over five years. The buyer-side engagement split the workload: Oracle Database and the broadcast egress-heavy services to OCI Universal Credits (2:1 multiplier, 10 TB/region free egress, $260K Support Rewards offset over the term); residual application tier and analytics on AWS with 3-year Savings Plans. Net 5-year TCO across both clouds: $3.2M. Compared to the AWS-only baseline, the multi-cloud split delivered $1.6M in savings, of which $720K was egress alone. The customer reports stronger negotiating leverage at every renewal cycle by holding both vendors against each other.
On list price, OCI undercuts AWS materially on compute, block storage, and especially network egress (OCI gives 10 TB/region/month free, then $0.0085/GB; AWS charges $0.09/GB after the first 100 GB/account/month). On heavily-discounted AWS Reserved Instance or Savings Plans contracts, the gap narrows significantly. For Oracle Database BYOL workloads, OCI's Support Rewards programme and BYOL multipliers shift the comparison further. The right comparison is always negotiated rate vs negotiated rate, not list vs list.
Support Rewards is Oracle's loyalty mechanic: 25 percent of qualifying OCI Universal Credits consumption can be applied against Oracle technology support invoices, with Unlimited License Agreement customers getting 33 percent. It is one of OCI's strongest commercial differentiators against AWS for organisations with substantial Oracle on-premise estate. AWS has no analogous mechanism. We cover Support Rewards mechanics in detail in the Oracle support cost reduction guide.
Oracle BYOL on OCI receives a 2:1 vCPU-to-Processor licence multiplier — one Processor licence covers two OCI vCPUs. On AWS, the same Processor licence covers one vCPU (no multiplier). The combination of the multiplier plus Support Rewards plus generally lower OCI compute prices is the strongest commercial argument for Oracle workloads on OCI.
AWS wins on service breadth (over 200 services to OCI's roughly 100), regional coverage (more regions), mature managed services in serverless, container, AI, and observability, and the ecosystem of third-party integrations. For workloads where Oracle Database is not a major footprint, AWS is usually the better choice on overall TCO and ecosystem fit.
Structural. AWS's $0.09/GB egress after the first 100 GB compares to OCI's 10 TB/region/month free tier plus $0.0085/GB beyond. For media, content delivery, multi-cloud, or DR workloads, the egress line alone can flip the TCO comparison in OCI's favour by hundreds of thousands of dollars over a five-year term.
Rarely the right answer. All-in OCI eliminates the competitive pressure that keeps Oracle's account team honest at renewal. Multi-cloud — Oracle Database and egress-heavy services on OCI, residual workloads on AWS — typically delivers lower TCO and stronger negotiating leverage. We cover multi-cloud Oracle strategy in the Oracle cloud licensing guide.
