🗂️ Xloud XAVS – Multi-Cloud Object Storage Integration
1. 🔎 Introduction
Xloud XAVS OpenStack provides built-in, multi-cloud object storage integration, enabling customers to securely store and access files across public and private object storage systems. This includes support for:
- Backup targets for VM snapshots and workload protection
- Archival storage for logs, images, and compliance data
- Deployment repositories for ISO images and configuration templates
- Glance image storage as a scalable backend
Customers can seamlessly integrate with both OpenStack-native Swift and external object storage providers, including AWS S3, Google Cloud Storage, Azure Blob, Dell EMC ECS, and Ceph RGW.
2. 🧱 Architecture Overview
🔹 Unified Object Storage Framework
| Integration Layer | Description |
|---|---|
| OpenStack Swift | Native object storage, multi-tenant, integrated with Keystone and Horizon |
| S3-Compatible APIs | External access via Rclone, s3fs, Glance plugins, or backup tools |
| Glance Integration | Glance stores images in Swift or S3-compatible systems |
| Automation Tools | Ansible and Terraform workflows to manage storage tasks |
3. ✨ Supported Storage Platforms
| Provider | Protocol/API | Scope |
|---|---|---|
| OpenStack Swift | Swift REST API | Native |
| Ceph RGW | S3-Compatible | Native/External |
| AWS S3 | S3 | External |
| Google Cloud Storage | REST/S3-Compatible | External |
| Azure Blob Storage | REST API | External |
| Dell EMC ECS | S3-Compatible | External |
✅ All supported object storage types are compatible with secure credential storage, lifecycle automation, and tenant-level access controls.
4. 🧰 Use Cases
| Use Case | Purpose |
|---|---|
| Backup | Store snapshots and workload backups from tools like Trilio and Veeam |
| Archive | Retain system logs, historical data, and compliance backups |
| Deployment | Host scripts, images, and deployment assets for automation tools |
| VM Images | Use object storage as Glance backend to store and serve QCOW2/ISO |
5. 🔧 Integration Paths
✅ 1. Swift as Primary Object Store
Use for Glance, backup targets, or deployment artifacts.
Example Glance config (glance-api.conf):
[glance_store]
stores = file, http, swift
default_store = swift
swift_store_auth_version = 3
swift_store_auth_address = http://keystone:5000/v3
swift_store_container = glance-images
swift_store_create_container_on_put = True✅ 2. S3-Compatible Buckets for Backup & Archive
Supported in TrilioVault, Veeam, Bacula, etc.
TrilioVault example:
[object_storage]
type = s3
s3_url = https://s3.my-backup-domain.com
access_key = <access-key>
secret_key = <secret>
bucket = trilio-backupsBacula example:
Device {
Name = S3BackupDevice
DeviceType = Cloud
Cloud = "AWS"
BucketName = "bacula-backups"
}✅ 3. S3 as Glance Backend (Ceph RGW, ECS, etc.)
Glance with S3-compatible backend:
[glance_store]
stores = s3
default_store = s3
s3_store_host = s3.Xloud.local:8080
s3_store_access_key = <access-key>
s3_store_secret_key = <secret-key>
s3_store_bucket = glance-images
s3_store_create_bucket_on_put = True💡 Works with Ceph RGW, Dell ECS, MinIO, and AWS S3 endpoints.
✅ 4. Deployment Integration (Ansible/Terraform)
Use object buckets to host deployment assets like:
- QCOW2 images
- ISO files
- Cloud-init templates
Ansible Example (Rclone):
- name: Download image from S3 bucket
shell: rclone copy s3:deploy-images/ubuntu-22.qcow2 /var/lib/glance/images/Terraform Example:
- Define a
user_datascript that pulls files from object storage using presigned URLs or mounted buckets.
6. 🔐 Security & Governance
| Feature | Description |
|---|---|
| Keystone + Swift | Multi-tenant access control with token auth |
| IAM/STSe | Secure access to AWS/GCP/Azure-compatible endpoints |
| Barbican | Secret storage for keys and credentials |
| RBAC | Access scoped by project, role, and resource type |
7. 📦 Automation & Lifecycle
- Image lifecycle rules: Move outdated images to S3 Glacier or IA tiers
- Backup rotation: Ansible jobs or cron tasks to clean up or archive
- Object versioning & audit: Supported in S3 and Swift for compliance
- CI/CD ready: Pull artifacts into build pipelines directly from buckets
8. ✅ Summary Table
| Use Case | Tool/Service | Recommended Bucket Backend | Access Method |
|---|---|---|---|
| Backup | Trilio, Veeam, Bacula | Swift, S3, Ceph RGW, ECS | API (Swift/S3) |
| Archive | Bacula, Rclone | S3 Glacier, Azure Archive, ECS | API (via CLI/SDK) |
| Deployment | Ansible, Terraform | Swift, S3 | Pre-signed URLs or mount |
| VM Images | Glance | Swift, Ceph RGW, ECS | Glance store driver |
✅ Final Positioning
Xloud XAVS offers a unified, secure, and extensible object storage framework for multi-cloud environments. Customers can leverage object buckets for:
- VM backup and long-term archival
- Rapid deployment of cloud-native workloads
- Flexible Glance image storage and sharing
- Multi-tenant governance and automation
🟢 Customer Experience: No extra setup is needed—just point your tools to the integrated object storage, and Xloud handles the rest.
