GCP Consulting & Architecture is independent advisory from certified Google Cloud architects who design, review, and remediate your Google Cloud environment — before and after migration. PrecisionTech engagements cover landing zone design (Organization, Shared VPC, IAM, logging, billing), Well-Architected Framework-style reviews across five pillars (reliability, security, cost, performance, operations), multi-cloud advisory against AWS and Azure, and roadmap workshops producing phased 12–24 month plans with architecture diagrams and INR cost models.
PrecisionTech is an Authorized Google Cloud Partner delivering architecture consulting across India — with deep expertise on AWS and Azure for unbiased multi-cloud recommendations. We identify architectural risks before production spend, not after an outage.
Every architecture deliverable PrecisionTech produces for Indian enterprises
A GCP landing zone is the secure, repeatable foundation every project inherits — Organization hierarchy, Shared VPC, centralized IAM, logging, billing, and security baselines. Without it, teams accumulate shadow IT: inconsistent controls, untagged resources, and compliance gaps that are expensive to retrofit after workloads go live.
Google Cloud provides equivalent guidance through the Google Cloud Architecture Framework and Cloud Setup Checklist. PrecisionTech conducts structured assessments mapped to five pillars familiar to enterprise architects — the same rigour as an AWS Well-Architected Review, adapted for GCP services and India regulatory context.
| Pillar | What We Assess | Common Findings (India) |
|---|---|---|
| Reliability | SLOs/SLIs, multi-zone GKE, Cloud SQL HA, DR between Mumbai & Delhi, backup restore testing | Single-zone clusters, untested backups, missing cross-region replicas |
| Security | IAM least privilege, Workload Identity, CMEK, VPC Service Controls, Security Command Center, Cloud Armor | Public Cloud Storage buckets, over-privileged SAs, missing audit logs |
| Cost Optimization | Recommender insights, CUD strategy, Spot VMs, idle disks, BigQuery slot analysis | Lift-and-shift oversizing, no labels, missing budgets and alerts |
| Performance | GCE vs GKE vs Cloud Run selection, Premium Tier, CDN, database tuning, TPU/GPU for ML | Wrong compute tier, no connection pooling, missing load testing |
| Operations | Terraform coverage, Cloud Build CI/CD, observability, incident runbooks, platform team model | Manual Console changes, no structured logging, missing on-call process |

PrecisionTech provides Google Cloud Platform (GCP) consulting and architecture services for Indian enterprises, SMBs, and startups — from greenfield design to review and remediation of existing environments. Our engagements typically include:
Every engagement is delivered by Google Cloud Professional Cloud Architect-certified consultants. Request a free architecture assessment to get started.
A GCP architecture review is a structured evaluation of your Google Cloud environment — or a proposed design — to identify risks, gaps, and optimization opportunities before they become production incidents or cost overruns. PrecisionTech conducts reviews for organizations at every stage:
Deliverables include a prioritized findings report (Critical / High / Medium / Low), remediation recommendations with effort estimates, and architecture diagrams showing current vs recommended state. Most reviews complete in 5–15 business days depending on environment complexity. Book a discovery call to scope your review.
A GCP landing zone is a pre-configured, secure, and scalable foundation that every project and workload inherits from day one — rather than each team building its own VPC, IAM, and logging in isolation. Without a landing zone, organizations accumulate shadow IT: inconsistent security controls, untagged resources, billing surprises, and compliance gaps that are expensive to retrofit later.
PrecisionTech landing zone designs typically include:
We use Google's Cloud Foundation Toolkit and Terraform modules where appropriate, producing version-controlled, repeatable infrastructure. Landing zone setup is typically the first deliverable in every PrecisionTech GCP engagement — whether you are migrating from on-premises, AWS, or Azure.
The GCP Organization is the root node of your Google Cloud resource hierarchy. PrecisionTech designs Organization structure to enforce governance, billing separation, and blast-radius containment:
constraints/gcp.resourceLocations), disable service account key creation, require OS Login, restrict public IP assignment, and enforce uniform bucket-level accessThis hierarchy mirrors how Google operates internally and aligns with the Google Cloud Setup Checklist and Cloud Foundation Toolkit reference architectures. We document the folder tree, project naming conventions, and IAM inheritance rules in your Architecture Decision Record (ADR) pack.
Shared VPC lets you centralize VPC network administration in a host project while application teams deploy resources in separate service projects that attach to the shared network. This is the GCP equivalent of AWS Transit Gateway hub-and-spoke or Azure Hub-Spoke topology — and it is the recommended network model for enterprises running multiple workloads on GCP.
PrecisionTech Shared VPC designs include:
Benefits: consistent security posture, simplified audit (one place to review network rules), reduced IP address fragmentation, and faster project onboarding — new teams get a service project attached to an existing Shared VPC in hours, not weeks.
Cloud IAM on GCP follows a resource hierarchy — Organization → Folder → Project → Resource — where permissions inherit downward and can be constrained by Organization Policy. PrecisionTech designs IAM to enforce least privilege, eliminate standing admin access, and support audit requirements:
run.services.update but not run.services.delete)request.time conditions), IP-restricted bindings, and resource-tag-based conditions for fine-grained controlWe produce an IAM matrix mapping every group, role, and scope — a deliverable auditors and compliance teams expect for DPDP Act, RBI, and ISO 27001 reviews.
Google Cloud does not publish a product named "Well-Architected Framework" (that term originates with AWS), but Google provides equivalent guidance through the Google Cloud Architecture Framework, Cloud Setup Checklist, and pillar-specific best-practice documentation. PrecisionTech conducts Well-Architected Framework-style GCP reviews — structured assessments mapped to five pillars familiar to enterprise architects:
Each pillar receives a score and prioritized remediation backlog. Reviews typically run as a 2-day workshop with your engineering and security teams, followed by a written report within one week. Ideal timing: after landing zone setup, before major migration waves, or annually for mature environments.
The Reliability pillar evaluates whether your GCP workloads meet availability and recovery objectives — and whether your architecture can absorb failures without customer impact. PrecisionTech assesses:
Common findings in Indian enterprise reviews: single-zone GKE clusters, Cloud SQL without HA enabled, missing backup verification (backups exist but restore has never been tested), and DNS TTLs too high for fast failover. We provide a remediation roadmap ranked by risk and effort.
The Security pillar evaluates identity, data protection, network isolation, threat detection, and compliance readiness. PrecisionTech assesses:
Security findings are classified by exploitability and data sensitivity. Critical items (public Cloud Storage buckets with PII, over-privileged service accounts, missing audit logging) are flagged for immediate remediation.
The Cost Optimization pillar identifies waste, right-sizing opportunities, and discount strategies — critical because many organizations overspend 25–45% on GCP in the first year due to lift-and-shift sizing and unused resources. PrecisionTech assesses:
Every cost review includes an INR savings estimate with prioritized quick wins (typically achievable in the first 30 days) and longer-term CUD procurement recommendations.
The Performance Efficiency pillar evaluates whether you are using the right GCP services, instance types, and configurations for each workload — balancing performance, cost, and operational complexity. PrecisionTech assesses:
Performance recommendations include architecture diagrams showing service changes (e.g., migrating a monolithic GCE VM to Cloud Run with concurrency tuning) with expected latency and cost impact.
The Operational Excellence pillar evaluates how well your teams can deploy, monitor, respond to incidents, and evolve the platform over time. PrecisionTech assesses:
Operational gaps are the most common source of slow incident response and deployment friction. We prioritize fixes that reduce mean time to recovery (MTTR) and increase deployment confidence.
PrecisionTech provides unbiased multi-cloud advisory — we are an Authorized Google Cloud Partner with deep expertise across Amazon AWS and Microsoft Azure, so recommendations are driven by your workload requirements, not vendor preference.
When evaluating GCP vs AWS, we compare across dimensions that matter to Indian businesses:
Deliverable: a decision matrix with weighted scoring, TCO comparison in INR, and a recommended primary cloud with optional secondary for specific workloads (e.g., GCP for analytics/AI, AWS for legacy ERP).
For organizations comparing GCP vs Microsoft Azure, PrecisionTech evaluates fit based on your application portfolio, team skills, and regulatory context — not generic feature checklists.
Key comparison dimensions:
We also advise on rational multi-cloud — running GCP for data/AI while keeping Azure for Microsoft-centric workloads is a common and valid pattern. The goal is avoiding unnecessary complexity: two clouds should serve distinct strategic purposes, not duplicate the same workload. See our full AWS vs Azure vs Google Cloud comparison for a detailed side-by-side analysis.
A GCP roadmap workshop is a structured 1–3 day engagement where PrecisionTech architects work with your leadership and engineering teams to produce a phased plan for cloud adoption, migration, or modernization on Google Cloud.
Workshop agenda typically covers:
Deliverables (delivered within 5–10 business days after the workshop):
Roadmap workshops are ideal before board-level cloud investment decisions or RFP preparation. Schedule a roadmap workshop with our architecture team.
ADAPT (Assess, Define, Adapt, Plan, Transform) is Google's recommended migration methodology. PrecisionTech integrates ADAPT into every architecture engagement — consulting is not separate from migration planning; the landing zone and target architecture are the migration foundation.
Architecture consulting deliverables map directly to ADAPT phases: landing zone design = Adapt; Well-Architected review = Assess + ongoing Transform; roadmap workshop = Define + Plan. This ensures your architecture investment accelerates migration execution rather than producing shelfware.
PrecisionTech consultants hold the Google Cloud Professional Cloud Architect certification — Google's highest-level credential for designing, developing, and managing robust, secure, scalable, and dynamic solutions on GCP. Our team also includes certified Professional Data Engineer, Professional DevOps Engineer, and Professional Cloud Security Engineer specialists for pillar-specific depth.
Professional Cloud Architect consulting engagements include:
Engagement models: fixed-scope architecture packages, time-and-materials advisory retainers, or embedded architect support during migration programs. Discuss your requirements — we respond during business hours, 11 AM–5 PM Mon–Fri (excl. holidays).
Indian regulatory requirements are not optional add-ons — they are design constraints that PrecisionTech embeds from the first architecture workshop. We map controls to specific GCP services and Organization Policy constraints:
Digital Personal Data Protection Act 2023 (DPDP Act)
constraints/gcp.resourceLocations restricting resource creation to in:asia-south1-locations,asia-south2-locationsReserve Bank of India (RBI) and sector regulators
Deliverable: a compliance mapping matrix linking each regulatory requirement to GCP controls, Organization Policies, and operational procedures — ready for internal audit or regulator inquiry.
Infrastructure as Code (IaC) is essential for repeatable, auditable, and drift-resistant GCP environments. PrecisionTech implements Terraform as the primary IaC tool — aligned with Google's official Cloud Foundation Toolkit (CFT) and Terraform modules.
Our IaC approach includes:
We also support Config Connector (Kubernetes-native GCP resource management) for teams already operating GKE-centric platforms, and Pulumi on request for teams preferring general-purpose programming languages over HCL.
IaC maturity is assessed in every Operational Excellence pillar review — organizations without IaC consistently show higher incident rates and slower environment provisioning.
Google Cloud operates two India regions — each with three Availability Zones — and architecture decisions around region selection directly affect compliance, latency, cost, and disaster recovery:
PrecisionTech architecture designs leverage both regions for:
Region selection is documented in your Architecture Decision Record with rationale for primary, DR, and any workload-specific exceptions.
