☁️Enterprise Cloud Architecture Design & Seamless Migration
Migrate legacy on-premise servers and unoptimized infrastructure to resilient, cost-effective AWS and Azure cloud environments following the 6Rs framework with zero operational downtime.
AWS Well-Architected & Azure Cloud Adoption Framework (CAF)
Zero-Downtime Live Database Replication & Cutover
FinOps Cloud Cost Optimization & Right-Sizing
Goafreet provides enterprise-grade cloud architecture design and migration services, transitioning organizations from fragile on-premise data centers or unoptimized hosting providers into secure, auto-scaling cloud environments on AWS, Microsoft Azure, and Google Cloud. Following the AWS Well-Architected Framework, our cloud architects in Vadodara methodically plan, execute, and validate cloud migrations with automated disaster recovery, least-privilege security, and strict cost governance.
Business Problems We Solve
Aging On-Premise Hardware Failures
Physical server components failing unpredictably, causing catastrophic business downtime and expensive emergency hardware replacements.
Inability to Handle Sudden Traffic Surges
Static hosting infrastructure crashing during peak customer traffic events due to lack of automated horizontal elasticity.
Escalating & Uncontrolled Cloud Invoices
Companies migrating to the cloud without architectural governance, resulting in runaway monthly compute bills and unattached storage volumes.
Lack of Geographic Redundancy & Disaster Recovery
All business operations dependent on a single physical data center with zero automated failover in case of power or network outages.
Who Benefits Most
Enterprises seeking to decommission physical on-premise server rooms and data centers
Growing SaaS and digital businesses needing auto-scaling multi-AZ high availability
Companies looking to optimize runaway cloud infrastructure costs through FinOps principles
Organizations preparing for compliance certifications (SOC-2, ISO 27001, HIPAA)
When to Consider Alternatives
Simple static websites hosted on basic shared hosting that have no scaling requirements
Companies requiring sovereign hardware with zero external internet connectivity
Organizations seeking informal lift-and-shift without security or architecture review
What Goafreet Actually Delivers

Cloud Readiness Assessment & Total Cost of Ownership (TCO)
Auditing on-premise server loads, network dependencies, and software licensing to model precise post-migration cloud operating costs.
• Automated discovery scanning of server CPU, RAM, and storage utilization
• Application portfolio evaluation against the 6Rs migration strategies (Rehost, Replatform, Refactor, etc.)
• 5-year Total Cost of Ownership (TCO) financial modeling comparing on-prem vs cloud
Well-Architected Landing Zone Architecture
Designing multi-account cloud landing zones with isolated Virtual Private Clouds (VPCs), transit gateways, and centralized logging.
• Multi-account AWS Organizations / Azure Management Groups setup
• VPC subnet segmentation (public, private, database) and security groups
• Centralized identity federation via Okta / Azure AD with least-privilege IAM
Zero-Downtime Live Database & Workload Migration
Executing continuous data synchronization between source and cloud destination using AWS DMS or Azure Database Migration Service.
• Change Data Capture (CDC) replication maintaining real-time data parity
• Server image replication (AWS Application Migration Service - MGN)
• Cutover rehearsal and off-peak final DNS switchover with sub-minute failback
Post-Migration FinOps & Cost Optimization
Implementing automated cost monitoring, rightsizing over-provisioned instances, and purchasing Reserved Instances / Savings Plans.
• Automated termination of orphaned EBS volumes, snapshots, and idle load balancers
• Spot Instance orchestration for non-production and batch processing workloads
• CloudWatch / Azure Monitor cost anomaly alerting and budget thresholds

Technologies & Platforms
Delivery Process & Decision Gates
Discovery & TCO Assessment
Scanning existing on-premise infrastructure, auditing application dependencies, and modeling cloud costs.
Landing Zone IaC Provisioning
Authoring Terraform code, provisioning secure VPCs, IAM policies, and setting up staging workloads.
Data Replication & Cutover Rehearsal
Establishing live database replication, migrating test workloads, and conducting mock cutover tests.
Production Cutover & Optimization
Executing off-peak DNS cutover, decommissioning legacy servers, and implementing cost optimization.
Governance & Cadence
Weekly migration project steering calls, shared Jira board tracking work streams, and 24/7 hyper-care support during production cutover.
Quality Assurance
Pre-cutover data verification scripts comparing database row counts and checksums character-for-character between on-premise and cloud.
Security & Privacy
Zero hardcoded credentials, all access managed via IAM roles with multi-factor authentication (MFA), and encrypted transit (TLS 1.3) and rest (AES-256).
Use Cases & Applications
Financial Services Data Center Decommissioning
Migrated 42 physical VMware servers to AWS Multi-AZ architecture with zero downtime, cutting annual infrastructure operating costs by 38%.
E-Commerce Auto-Scaling Migration for Diwali Spikes
Re-architected an unoptimized single-server Magento store onto auto-scaling AWS ECS containers, effortlessly handling a 12x traffic surge during festive sales.
Healthcare Provider Azure HIPAA Migration

How do you ensure zero downtime during a database migration?
We set up live Change Data Capture (CDC) replication tools like AWS Database Migration Service (DMS). The source database continues serving live traffic while changes are replicated to the cloud in real-time. During cutover, we simply pause writes for a few seconds, let the stream catch up, and switch DNS.
Should we migrate to AWS or Microsoft Azure?
Both platforms are world-class. If your organization relies heavily on Microsoft enterprise software (.NET, Active Directory, SQL Server, Office 365), Azure offers seamless integration and licensing benefits. For containerized microservices and broad developer tooling, AWS is often the industry preference. We evaluate your stack objectively.
How do you prevent cloud bills from spiraling out of control?
We implement Infrastructure as Code (IaC) with strict tag governance, auto-scaling rules that scale down during non-peak hours, automated termination of orphaned storage volumes, and purchasing of 1- or 3-year Savings Plans for predictable base workloads.
Who owns the cloud accounts and Terraform infrastructure scripts?
All cloud accounts are registered directly in your organization's legal name. All Terraform scripts, documentation, and configuration files are committed to your internal Git repository upon project completion.
