Infrastructure Design
Build Cloud Infrastructure That Scales Effortlessly, Performs Predictably, and Stays Cost-Efficient
We architect secure, resilient cloud and network foundations tailored to your goals.
From blueprint to deployment, i3RL designs systems that endure and evolve.
In today’s digital world, infrastructure is your product’s backbone. At i3RL, we design cloud and hybrid architectures that emphasize security, reliability, and cost efficiency so your teams can ship fast without compromise. Our approach is durable engineering: we favor clear designs, operational readiness, and observability from day one, producing foundations that teams can maintain confidently and scale predictably as demand grows.
Our Infrastructure Design Services
Cloud & Platform Architecture
We produce cloud reference designs across AWS, Azure, and GCP that turn business goals into concrete choices for identity, networking, storage, compute, resilience, and multi-region expansion. Each design is measured against the Well-Architected pillars to de-risk build-out and keep trade-offs explicit as the platform evolves.
Network & Security Architecture
We shape VPC/VNet topologies with segmentation, private connectivity, and policy-as-code built on zero-trust assumptions. Identity-centric controls and modern ingress/egress patterns reduce blast radius, simplify compliance, and keep consistent guardrails across hybrid and multicloud—without slowing developer workflows.

Data Platform Foundations
We design resilient data layers using PostgreSQL, MySQL, and MongoDB with encryption, backups, retention, and access patterns tuned to workload behavior. Plans align RPO/RTO with business impact so schemas, read/write paths, and operational routines scale cleanly into day-two operations.
High Availability & Disaster Recovery
We engineer graceful degradation and fast recovery using multi-AZ/region patterns, health-based routing, and proven failover runbooks. Pre-launch failure drills and capacity tests document how systems behave under stress and how to restore service quickly and confidently.
Infrastructure as Code (IaC)
We standardize environments with Terraform, CloudFormation, or Pulumi using reusable modules, security baselines, and CI/CD validations. Changes are peer-reviewed and auditable, keeping dev/stage/prod consistent and eliminating fragile, ad-hoc scripts.
Cost Architecture & FinOps
We build cost control into architecture with tagging and allocation standards, rightsizing and autoscaling, and budgets with alerts and ownership-tied dashboards. Cloud spend becomes a shared operational signal that improves efficiency without sacrificing performance or reliability.
Infrastructure Experience
Our team has spent a decade designing and evolving cloud and hybrid estates for startups and enterprises that operate
under mission-critical uptime, regulatory scrutiny, and rapid scaling demands. We prioritize clear ownership and
operational clarity so platforms are straightforward to run, easy to audit, and ready to expand into new regions, teams, and services without re-architecture.

Our Infrastructure Design Process
We turn business goals into reliable, scalable infrastructure. Our process defines measurable requirements, validates assumptions early, and codifies patterns as IaC. Before launch we prove reliability with testing and readiness checks—then use SLO-driven monitoring to keep improving after day one.
Conceptualizing the Product
We convert business objectives into non-functional requirements—SLA/SLO targets, compliance constraints, scale expectations, and budget guardrails—then define measurable success criteria that guide every later decision and keep stakeholders aligned on desired outcomes.
Project Kickoff
We establish stakeholders, communication cadence, and a transparent backlog in Jira or Trello, and we formalize architecture decision records so critical trade-offs and assumptions are captured, reviewed, and easy to revisit as the platform and requirements mature.
Discovery Phase
We assess the current state, dependencies, and constraints, and we validate feasibility with lightweight prototypes and benchmarks. This clarifies latency budgets, data flows, security assumptions, and failure modes before larger investments and reduces uncertainty in downstream work.
Reference Designs & Diagrams
We deliver living documents—logical and physical diagrams, data and trust boundaries, and an IaC module map—so teams have a single, versioned source of truth. Collaborative reviews make sure operational realities and developer experience are reflected before implementation.
Build-Out
We implement landing zones, identity, networking, and platform services as code with peer-reviewed pull requests and automated checks. This provides consistent environments, faster onboarding, and a reliable starting point for product teams to build and deploy safely.
Quality Assurance
We validate architecture through security reviews, performance testing, and failure drills so alerting thresholds, headroom, and recovery behavior match expectations. These exercises harden the platform and confirm that operational runbooks are accurate and actionable.
Release Preparation
We run operational readiness reviews, finalize documentation and runbooks, and verify the design against reliability and cost pillars. This stage de-risks launch by ensuring teams, tooling, and processes are prepared for real-world traffic and growth scenarios.
Post-Launch Support
We track SLOs and error budgets, tune alerts to reduce noise, and feed incident learnings into continual improvement so reliability stays aligned with product velocity. This creates a feedback loop where user impact and operational data guide the next set of platform refinements.
