Alfresco on AWS Deployment Architecture (2026): EC2, EKS, S3 & Cost Optimization
Deploying Alfresco Content Services (ACS) on Amazon Web Services can improve infrastructure flexibility, but architecture choices determine reliability and total cost of ownership. This practical guide covers an Alfresco AWS deployment architecture, Amazon EC2 versus EKS, S3 content storage, RDS PostgreSQL, search, messaging, security, cost assumptions, and configuration examples.
Technical scope: This is a reference design, not a ready-to-run production configuration. Validate your exact ACS version, licensed connectors, chart release, search compatibility, and AWS region before implementation.
Quick answer: Start with private Alfresco repository nodes behind an Application Load Balancer, RDS PostgreSQL, a supported S3 Content Connector, a version-compatible search stack, an ActiveMQ-compatible messaging service, and isolated transform services. Choose EC2 for simpler operational requirements or EKS when your team can maintain Kubernetes.

1. Alfresco AWS deployment architecture
In a resilient design, requests reach an HTTPS load balancer; the Alfresco application tier runs in private subnets; persistent metadata is stored in RDS; document binaries reside in S3 via a supported connector. Search, transformations, and asynchronous messaging are deployed and scaled separately.

| Layer | AWS service | Engineering decision |
|---|---|---|
| Edge | ALB, ACM, optional AWS WAF | HTTPS and a restricted public entry point |
| Repository / UI | EC2 Auto Scaling or Amazon EKS | Private nodes; separate sizing for repository, Share and Digital Workspace |
| Metadata | RDS for PostgreSQL | Version-supported driver, storage, backups; Multi-AZ if required |
| Binary document | Amazon S3 | Supported Alfresco S3 connector, IAM, encryption, lifecycle review |
| Full text search | Alfresco Search Services (Solr) or compatible Search Enterprise/OpenSearch design | Not interchangeable without migration and support verification |
| Messaging | Amazon MQ for ActiveMQ or supported broker | Do not substitute Amazon SQS without application-level changes |
| Renditions | Transform Service plus shared file store if needed | Size for document conversion workload |
| Operations | CloudWatch, IAM, KMS, Backup | Observability, secrets, encryption and recovery |
Official ACS Helm deployment documentation includes an AWS-services example using EKS with S3, RDS, Amazon MQ and OpenSearch. The correct search product depends on your Alfresco release and license. See ACS deployment with AWS services.
| Criteria | EC2 deployment | EKS deployment |
|---|---|---|
| Best fit | Smaller teams, familiar VM administration | Container platform teams operating multiple services |
| Complexity | OS patching, instances, deployment scripts | Kubernetes, Helm, cluster upgrades, pod operations |
| Elasticity | Auto Scaling with validation | Pod and node scaling with validation |
| Cost drivers | EC2, EBS, ALB, networking | EKS cluster fee plus worker compute, storage, networking |
| Recommendation | Start simple if workload is predictable | Use when platform expertise and scale justify it |
Important: Even if repository binaries move to S3, the database, search indexes and transform temporary/shared storage may still need separate persistent capacity.
3. AWS configuration examples
3.1 Create a private S3 content bucket
The bucket should be created in an approved AWS region. Use a globally unique bucket name and inspect retention, object-versioning, and deletion semantics before enabling costly policies.
aws s3api create-bucket \
--bucket YOUR-UNIQUE-ACS-BUCKET \
--region us-east-1
aws s3api put-public-access-block \
--bucket YOUR-UNIQUE-ACS-BUCKET \
--public-access-block-configuration \
BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true
aws s3api put-bucket-encryption \
--bucket YOUR-UNIQUE-ACS-BUCKET \
--server-side-encryption-configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}'These CLI examples use ; bucket-creation arguments differ for other AWS regions. IAM role policies and the installed S3 connector must be configured independently. For KMS-managed encryption, include the correct key policy and request charges in the cost model.us-east-1
3.2 RDS PostgreSQL connection properties
# Illustrative alfresco-global.properties fragment
# Check property support for your ACS version.
db.driver=org.postgresql.Driver
db.url=jdbc:postgresql://YOUR-RDS-ENDPOINT:5432/alfresco
db.username=alfresco
db.password=${ALFRESCO_DB_PASSWORD}Use a secure deployment-time property-resolution mechanism or secrets integration supported by your ACS release. Do not assume the placeholder syntax automatically reads environment variables in every Alfresco deployment. Restrict PostgreSQL port 5432 to application security groups and enable TLS according to your JDBC driver and certificate setup.
3.3 Configure a supported S3 content store
The correct S3 connector artifact and keys vary by release. Install the connector version officially compatible with your ACS version and follow its documented S3 subsystem instructions; avoid copying properties from an unrelated release. Documentation: Alfresco Content Connector for AWS S3.alfresco-global.properties
3.4 An illustrative deployment topology
Internet clients
-> HTTPS / ALB / optional WAF
-> Private application nodes: Alfresco repository + UI
-> RDS PostgreSQL (metadata)
-> S3 via compatible connector (document content)
-> Solr Search Services OR supported Search Enterprise stack
-> Amazon MQ / compatible ActiveMQ broker
-> Transform services and temporary/shared storage
-> CloudWatch, backup policies and security controlsWhen running EKS, follow the maintained Helm chart and official AWS deployment example for your target release rather than treating a generic values.yaml snippet as production-ready.
4. Alfresco AWS monthly cost estimate: transparent assumptions
Below is a worked budgeting scenario, not live AWS pricing or a vendor quote. Assume 730 hours/month, one region, Linux on-demand workloads, approximately 2 TB of stored documents, modest document processing, and no unusually high transfer or reindex spikes. Prices are rounded illustrative planning allowances in USD. Real charges differ significantly across AWS regions, instance classes, HA designs, purchase commitments and service tiers.
| Cost item | Assumption | Illustrative USD/month |
|---|---|---|
| Application compute | Two modest repository/UI nodes | $350 |
| Search capacity | Dedicated search compute + volumes | $300 |
| Transform / ancillary services | One modest service allocation | $130 |
| RDS PostgreSQL | Instance, storage and backups allowance | $280 |
| S3 documents | 2 TB × assumed $0.023/GB-month (~2,048 GB) | $47 |
| ALB and networking | Load balancer, NAT, data transfer allowance | $200 |
| Amazon MQ | Broker allowance | $120 |
| Monitoring / snapshots | Logs, metrics, backup overhead | $100 |
| Illustrative subtotal | $1,527/month | |
Arithmetic: $350 + $300 + $130 + $280 + $47 + $200 + $120 + $100 = $1,527/month, or $18,324/year before taxes. The S3 example assumes decimal-style GB billing and rounded quantities; request, retrieval, lifecycle transition and replication charges are excluded.
To create a region-specific estimate, open the AWS Pricing Calculator, then add EC2/EKS, RDS, S3, ALB, Amazon MQ, EBS/EFS, CloudWatch, NAT Gateway and data-transfer usage separately.
5. Nine practical cost-optimization levers
- Right-size after measurement: Collect JVM heap, CPU, memory, request throughput and garbage collection metrics over a representative workload.
- Keep search separate: Size Solr/OpenSearch for index volume, query concurrency, shards and reindex requirements; avoid oversized clusters by default.
- Use S3 lifecycle rules cautiously: Moving active Alfresco content to infrequent-access or archive tiers can cause retrieval penalties or application failures. Test connector behavior and restoration expectations first.
- Review database capacity: Track connection pools, IOPS, storage growth, backup retention and Multi-AZ requirements before changing instance classes.
- Reduce inter-AZ and NAT transfer: Inspect repeated application-to-storage transfers and consider supported VPC endpoints where beneficial.
- Scale transforms independently: CPU-heavy OCR, PDF and office rendition workloads should not force permanent overprovisioning of repository nodes.
- Use purchase discounts on stable loads: Evaluate Savings Plans or reservations only after confirming steady-state consumption.
- Control observability spend: Put practical retention periods on CloudWatch logs, and monitor high-cardinality metrics.
- Set AWS Budgets and tags: Track separate environments and components so unexpected search, egress or snapshot costs are visible.
6. Production deployment and migration checklist
- Confirm supported ACS, Java, database, search and S3 Connector version combinations.
- Choose single-AZ vs Multi-AZ deliberately; document RTO/RPO and recovery testing.
- Put repositories, search, database and brokers in private subnets.
- Configure TLS, least-privilege IAM, encryption and secrets rotation.
- Validate object write/read/delete and retention behavior before S3 cutover.
- Test custom AMPs/JARs, audit integrations, workflows and transforms.
- Measure baseline JVM heap, Solr reindex time, DB IOPS, worker queues and latency.
- Test sustained load, failover, restore and end-to-end document lifecycle.
- Calculate total cost with region-specific pricing and projected growth.
- Set alerts and review costs 7, 30 and 90 days after rollout.
7. Frequently asked questions
Is AWS S3 enough for Alfresco persistence?
No. S3 can hold document binaries when a supported connector is configured; Alfresco still needs metadata persistence, search indexes and potentially transform shared storage.
Should I deploy Alfresco on EC2 or EKS?
EC2 is often simpler for teams without Kubernetes operational experience. EKS can be appropriate for organizations already operating production container platforms. Compare total engineering effort, not just compute charges.
Can Alfresco Search Services be replaced with Amazon OpenSearch directly?
No universal drop-in replacement should be assumed. Search Services (Solr) and Alfresco Search Enterprise have different integration and support models; verify the product version and migration requirements.
How much does Alfresco on AWS cost per month?
There is no universal amount. This post models an illustrative $1,527/month infrastructure-only case; actual costs depend on compute sizing, search design, deployment availability, region and licenses.
Will S3 Glacier always reduce Alfresco costs?
No. Storage savings can be offset by retrieval delays and charges, and direct archiving of live content may violate application expectations. Test policies on suitable cold data and compatible connectors first.om
