Skill: DevSecOps Free Cloud

Goal

Identify and catalog free tier cloud compute, storage, and networking offerings suitable for DevSecOps infrastructure.

Use This Skill When

• Planning cloud infrastructure with zero budget
• Comparing free tiers across GCP, AWS, Azure, Oracle Cloud, IBM Cloud
• Setting up development/test environments at no cost

Do Not Use This Skill When

• Production workloads requiring SLAs
• Enterprise compliance requirements

Inputs

• Compute requirements (vCPU, RAM, hours/month)
• Storage requirements (GB, IOPS)
• Network requirements (bandwidth, regions)

Steps

1. Inventory Major Cloud Free Tiers

   • Google Cloud Platform (GCP)

     • Compute: 1 e2-micro instance (certain regions only)
     • Storage: 5GB Cloud Storage, 30GB HDD
     • Cloud Run: 2M requests/month
     • Cloud Functions: 2M invocations/month
     • BigQuery: 1TB queries/month, 10GB storage
     • GKE: 1 zonal cluster free (REDACTED_SECRETs charged)

   • Amazon Web Services (AWS)

     • EC2: 750 hours/month t2/t3.micro (12 months)
     • Lambda: 1M requests/month (forever)
     • S3: 5GB storage (12 months)
     • DynamoDB: 25GB NoSQL (forever)
     • CloudFront: 1TB egress/month (forever)
     • CodeBuild: 100 build-minutes/month

   • Microsoft Azure

     • VMs: 1 B1S Linux/Windows (12 months)
     • Functions: 1M requests/month (forever)
     • Cosmos DB: 25GB, 1000 RUs
     • App Service: 10 apps (60 CPU-min/day)
     • Azure DevOps: 5 users, unlimited repos
     • Static Web Apps: free tier with auth

   • Oracle Cloud

     • Compute: 2 AMD VMs (1/8 OCPU, 1GB), 4 Arm cores/24GB
     • Storage: 200GB block, 10GB object
     • Bandwidth: 10TB egress/month
     • Always Free (no time limit)

   • IBM Cloud

     • Cloudant: 1GB NoSQL
     • Db2: 100MB
     • API Connect: 50K calls/month
     • Log Analysis: 500MB/day

   • Cloudflare

     • Workers: 100K requests/day
     • Pages: 500 builds/month, unlimited static
     • R2: 10GB storage, 1M Class A ops, 10M Class B ops
     • D1: 5M rows read/day, 100K writes/day

2. Document Limitations

   • Credit card requirements for signup
   • Region restrictions (GCP e2-micro limited regions)
   • Time limits (12-month trials vs forever free)
   • Idle instance reclamation (Oracle Cloud)

3. Compare for Use Case

   • Development vs staging environments
   • CI/CD runners
   • Database hosting
   • Static site hosting

Output

• Comparison table of free cloud resources
• Service selection recommendations
• Limitations and caveats

Key Considerations

• Oracle Cloud offers the most generous "always free" tier
• AWS/Azure free tiers expire after 12 months
• GCP free tier has regional restrictions
• Cloudflare excellent for edge compute/CDN
