Cloud Infrastructure Consulting — Multi-Cloud Design
Cloud infrastructure decisions made today constrain your business for years. The wrong VPC design locks you into expensive networking workarounds. Overly permissive security groups become permanent when applications depend on them. Untagged resources make cost allocation impossible. Opsio's cloud infrastructure consulting provides the architecture expertise that prevents these mistakes — designing infrastructure that is secure, scalable, cost-efficient, and operationally manageable from the start.

What is Cloud Infrastructure Consulting?
Cloud infrastructure consulting provides expert guidance on designing, deploying, and managing compute, networking, storage, and security infrastructure on public cloud platforms — including multi-cloud architecture, infrastructure as code, and operational best practices.
Design Infrastructure That Scales With Your Business
Most cloud infrastructure problems are architecture problems. Organisations deploy resources reactively — a VM here, a database there, a VPN tunnel when someone needs connectivity — without a coherent design that addresses networking, security, identity, cost management, and operational efficiency holistically. Over time, these tactical decisions accumulate into an infrastructure estate that is expensive to run, difficult to secure, and impossible to manage consistently. Refactoring poorly designed infrastructure is 5-10x more expensive than designing it correctly from the start. Opsio's cloud infrastructure consulting provides the architectural foundation that prevents infrastructure sprawl. We design multi-cloud and hybrid architectures on AWS, Azure, and GCP using proven patterns: landing zones with governance guardrails, hub-and-spoke networking with proper segmentation, identity federation, encryption standards, tagging frameworks for cost allocation, and infrastructure as code using Terraform for reproducibility. Every design decision is documented in architecture decision records (ADRs) so your team understands not just what was built, but why.
Our consulting engagements range from focused assessments (security review, cost optimisation, Well-Architected review) to comprehensive infrastructure design and implementation projects. We work alongside your engineering team, transferring knowledge through pair programming and design workshops. The result is infrastructure your team understands and can evolve independently, with Opsio available for ongoing guidance and managed operations if needed.
What We Deliver
Multi-Cloud Architecture
Designing infrastructure across AWS, Azure, and GCP with consistent networking, security, and operational patterns. Cloud selection guidance based on workload requirements, existing investments, and team expertise. Hybrid connectivity for on-premises integration.
Landing Zone Design
Enterprise-scale landing zones with account/subscription structure, networking topology, security controls, identity integration, and governance policies. Deployed via Terraform for reproducibility across environments.
Infrastructure as Code
Terraform module development for standardised resource deployment across all cloud providers. Module libraries with CI/CD integration, automated testing, and version-controlled state management. Eliminating manual infrastructure provisioning entirely.
Network Architecture
VPC/VNet design with proper segmentation, transit gateway or Virtual WAN for multi-VPC connectivity, private link for service access, VPN and ExpressRoute/Direct Connect for hybrid connectivity, and CDN configuration for global performance.
Security Architecture
Defense-in-depth infrastructure security: network segmentation, WAF, DDoS protection, encryption, IAM least-privilege, secrets management, and security monitoring. CIS benchmarks and compliance framework alignment.
Cost Architecture
Designing for cost efficiency from the start: right-sized resource selection, Reserved Instance and Savings Plan strategy, storage tiering, auto-scaling policies, and tagging frameworks for cost visibility and allocation.

Multi-cloud expertise
Certified architects across AWS, Azure, and GCP who recommend the right platform for each workload rather than defaulting to a single vendor.
Terraform-native
Every infrastructure design is implemented as Terraform modules — reproducible, testable, and version-controlled from the first resource.
Architecture, not just resources
We design coherent infrastructure architectures with documented decisions — not random collections of cloud resources.
Knowledge transfer built in
Design workshops, pair programming, and ADRs ensure your team can maintain and evolve the infrastructure independently.

Cloud Infrastructure Consulting — Multi-Cloud Design FAQ
What does cloud infrastructure consulting include?
Opsio's consulting covers multi-cloud architecture design, landing zone implementation, infrastructure as code development with Terraform, network architecture, security hardening, cost optimisation, and operational best practices. Engagements range from focused assessments (2-3 weeks) to comprehensive design and implementation projects (2-4 months). Every engagement produces actionable deliverables — Terraform modules, architecture documentation, and security remediation plans.
Should we use AWS, Azure, or both?
The right choice depends on your existing investments, application requirements, team skills, and vendor relationships. Microsoft-centric organisations often benefit from Azure's native integration with Active Directory, Office 365, and Dynamics. AWS offers the broadest service catalogue and deepest compute/ML capabilities. Multi-cloud makes sense when you have specific workloads better suited to different platforms or want to avoid vendor lock-in. Opsio provides vendor-neutral guidance based on your specific situation.
Why is infrastructure as code important?
Infrastructure as code (IaC) with Terraform eliminates manual provisioning — every resource is defined in version-controlled code that can be reviewed, tested, and reproduced. Benefits include: consistent environments across dev, staging, and production; audit trails for every infrastructure change; automated deployment through CI/CD pipelines; disaster recovery by re-deploying from code; and elimination of configuration drift. Organisations using IaC experience 60% fewer outages caused by configuration errors.
How long does a cloud infrastructure consulting engagement take?
Focused assessments (security review, cost optimisation, architecture review) take 2-3 weeks. Landing zone design and implementation runs 4-8 weeks. Comprehensive infrastructure redesign projects take 2-4 months depending on scope. We recommend starting with an assessment to identify priorities, then implementing in phases that deliver value incrementally.
