AWS Consulting Services — Architecture & Optimisation

Most organisations use a fraction of AWS capabilities and overpay for what they do use. EC2 instances run oversized because nobody profiled the actual workload. S3 buckets lack lifecycle policies, accumulating terabytes of data that should have moved to Glacier months ago. Security groups allow overly broad access because the original developer took a shortcut during a deadline. These inefficiencies compound silently until the monthly bill triggers an executive review — by which point you have months of architectural debt to unwind. Opsio's AWS consulting services are advisory-first: the deliverables you receive are architecture documents, Well-Architected Review reports, Terraform modules, IAM policy rewrites, and prioritised cost-savings analyses — not invoices for 24/7 operations or a migration cutover. This page is intentionally distinct from our execution sibling at AWS migration services, where MGN, DMS, MAP funding and 7Rs cutover plans live, and from our steady-state operations practice at AWS managed services, which assumes ownership of CloudWatch, patching, GuardDuty, and incident response after consulting has shaped the environment. Use this page when you need outside-in opinion: an architecture reality check, a cost reduction plan, a security baseline against CIS AWS Benchmarks, or a roadmap to retire technical debt before it becomes operationally painful.

The engagement is anchored on the six pillars of the AWS Well-Architected Framework — operational excellence, security, reliability, performance efficiency, cost optimisation, and sustainability. A Well-Architected Review interviews your engineers, inspects accounts via read-only IAM roles, and produces a findings document scored by risk and impact, with prioritised remediation work that your team or ours can execute. Cost-optimisation consulting goes further than a Trusted Advisor screenshot: we baseline twelve months of consumption, model Reserved Instance and Savings Plan coverage scenarios using our cloud cost optimisation services playbook, and rebuild S3 lifecycle policies, RDS sizing, and Auto Scaling configurations in pull-request-ready Terraform — so the savings actually ship.

Security engagements harden IAM policies, design landing-zone guardrails with Control Tower and Service Control Policies, and align controls to SOC 2 and ISO 27001 evidence packages. DevOps consulting reviews your CI/CD posture, codifies infrastructure using Terraform with state, modules, and Sentinel/OPA policies. We pair every recommendation with reading: the Well-Architected Framework foundation guide for stakeholders, and the Well-Architected Review value brief for sponsors who need to justify the engagement upward. Every consulting engagement produces actionable deliverables — architecture diagrams, Terraform modules, security remediation plans, cost-savings reports — not slide decks that gather dust. We implement alongside your team, transferring knowledge through pair programming and architecture decision records so your organisation builds lasting AWS competency.
