Deploying a robust and scalable cloud infrastructure is no longer optional; it’s essential. For businesses seeking agility, efficiency, and cost optimisation, choosing a proven cloud management platform is key. Apache CloudStack, an open-source Infrastructure-as-a-Service (IaaS) platform, is gaining traction as a powerful alternative to proprietary cloud environments.

At Tetra, we specialise in deploying and supporting CloudStack-based cloud infrastructures that are tailored to meet specific business goals. This blog offers a comprehensive guide to the best practices for deploying CloudStack, drawing on our hands-on experience with organisations across industries.

Understanding CloudStack: A Brief Overview

Before diving into best practices, it’s important to understand what CloudStack is. Apache CloudStack is an open-source software designed to deploy and manage large networks of virtual machines as a highly available, scalable cloud computing platform. It supports:

  • Multiple hypervisors (KVM, VMware, XenServer)
  • Advanced networking and security controls
  • Rich REST APIs for integration
  • UI and CLI-based management
  • Public, private, and hybrid cloud models

Planning the CloudStack Deployment

A successful CloudStack deployment begins with a solid foundation:

  • Define Clear Objectives: Identify what your organisation hopes to achieve—be it workload scalability, multi-tenant provisioning, or cost optimisation. Your objectives will shape the architecture and resource allocation.
  • Assess Infrastructure Requirements: Audit your current data centre setup, including hardware, network architecture, and storage systems. CloudStack deployment requires precise planning of zones, pods, clusters, and hosts.
  • Choose the Right Hypervisor: CloudStack supports multiple hypervisors, but each has different requirements and use cases. KVM is preferred for open-source deployments, while VMware is used in more complex enterprise scenarios.
  • Design for Scalability and Redundancy: Design your cloud with high availability (HA) in mind. Distribute workloads across availability zones, deploy redundant components, and plan for disaster recovery.

Infrastructure Setup Best Practices

CloudStack relies on a well-configured infrastructure. Here’s how to ensure readiness:

  • Networking Configuration: Set up your network architecture before deployment. You’ll need to configure guest, management, public, and storage networks properly to ensure performance and security.
  • Secure and Harden Host Systems: Use hardened Linux distributions for CloudStack management servers. Keep systems up-to-date, disable unnecessary services, and enforce strict firewall and SSH rules.
  • Leverage Storage Best Practices: Choose storage solutions compatible with your workloads. Use primary storage for VM disks and secondary storage for templates and ISO images. For scalability, consider using Ceph, NFS, or iSCSI
  • DNS and Time Synchronisation: Ensure DNS resolution and NTP synchronisation work across all nodes. CloudStack heavily relies on these services to manage virtual machines and system logs.

CloudStack Installation and Configuration

Once your environment is ready, follow these steps for a seamless CloudStack installation:

  • Use the Right Version: Always deploy a stable and tested release of Apache CloudStack. Tetra can help identify the ideal version based on your business needs and plugin requirements.
  • Database Setup: Install and configure MySQL or MariaDB with optimal parameters. Use a dedicated database server with replication (if needed) for high availability.
  • API and Management Server: Deploy the CloudStack Management Server on a secure and optimised system. Configure the API endpoints for integration with billing, monitoring, and orchestration tools.
  • Add Infrastructure Components: Once the core is up, start adding zones, pods, clusters, hosts, networks, and storage. Follow the architecture hierarchy to avoid misconfigurations.

Post-Deployment Optimization

Even after deployment, CloudStack requires proactive management:

  • Resource Tagging: Tag your resources—VMs, storage, users, services—to improve visibility and simplify automation.
  • Use Templates and Service Offerings: Create pre-configured templates and custom service offerings for faster provisioning and consistent configurations.
  • Enable Logging and Monitoring: Implement log management using ELK Stack, and set up real-time monitoring using Nagios, Prometheus, or native CloudStack plugins. This helps in rapid troubleshooting and performance tuning.
  • Automate with Ansible or Terraform: Infrastructure as Code (IaC) is essential for repeatability. Automate provisioning and configuration tasks with Ansible, Terraform, or custom CloudStack APIs.

Security and Compliance Considerations

Security is a critical aspect of cloud deployment:

  • Role-Based Access Control (RBAC): Use CloudStack's domain and account-based access model to control who can do what. Assign permissions based on job roles and responsibilities.
  • Isolate Tenants: CloudStack offers advanced networking features that allow for secure tenant isolation, private IPs, and VLANs.
  • Patch Management: Regularly update your hypervisors and management servers. Automate security patches using configuration management tools.
  • Backup and Disaster Recovery: Integrate snapshot management and backup tools with your deployment. Use ZFS or Ceph snapshots, or configure VM backup to secondary storage.
