Our Cloud Application Delivery Methodology
No two cloud projects are identical. But every Flexsin engagement follows a repeatable framework that eliminates surprises and keeps delivery predictable.
-
01
Discovery & Cloud Readiness Assessment
We audit your current workloads, infrastructure, compliance requirements, and team capabilities - and map where cloud creates the most leverage for your business.
-
02
Cloud Strategy & Architecture Design
Our architects design a target-state cloud architecture - platform selection, network topology, security controls, and cost model - before a single resource is provisioned.
-
03
Environment Setup & Foundation Build
Landing zones, IAM policies, VPC design, and CI/CD scaffolding - the foundation is built right before applications move in. Infrastructure as code from day one.
-
04
Migration or Development & Testing
Workloads migrate in waves or applications are built sprint-by-sprint - with continuous integration, automated regression testing, and environment parity throughout.
-
05
Go-Live, Monitoring & Ongoing Optimisation
Post-launch isn't the finish line. Flexsin's CloudOps team tracks performance, cost trends, and security posture - continuously optimising what was built.

Frequently Asked Questions
Everything you need to know about Flexsin's cloud application services, process, platforms, and engagement models.
-
What cloud application services does Flexsin offer?
Flexsin offers end-to-end cloud application services including cloud-native development, cloud migration, application modernization, managed cloud operations, DevOps engineering, multi-cloud architecture, SaaS development, cloud security, and strategic cloud consulting.
-
Which cloud platforms does Flexsin work with?
We work across Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) - and design multi-cloud or hybrid cloud environments when your requirements call for it. Our engineers hold active certifications across all three platforms.
-
How do you approach cloud migration for legacy systems?
We use a structured 6R framework - Rehost, Replatform, Repurchase, Refactor, Retire, Retain - selecting the right strategy per workload. Every migration begins with a discovery assessment and ends with a validated, tested cutover plan to minimise downtime.
-
Can Flexsin help reduce our existing cloud costs?
Yes. Our FinOps assessments regularly identify 30-50% cost reduction opportunities through right-sizing, reserved instance planning, idle resource elimination, and storage tier optimisation - delivered as a prioritised action plan with measurable ROI.
-
How long does a typical cloud migration project take?
A lift-and-shift migration for a mid-size workload typically takes 8-16 weeks. Complex re-architecture engagements for enterprise-scale systems may run 6-12 months. We provide a detailed timeline after the initial discovery phase.
-
Do you support compliance requirements like HIPAA, SOC 2, and GDPR?
Yes. We design cloud environments with compliance-as-code - pre-built control sets, audit logging, data residency controls, and encryption standards aligned to HIPAA, SOC 2 Type II, GDPR, PCI-DSS, and ISO 27001 requirements.
-
What is your approach to cloud security?
Security is embedded from architecture design - not added after go-live. We implement zero-trust network models, least-privilege IAM, secrets management, runtime threat detection, vulnerability scanning, and SIEM integrations as standard deliverables.
-
Can you build a SaaS product on cloud infrastructure?
Absolutely. We design and build multi-tenant SaaS architectures from the ground up - tenant isolation models, subscription billing integration, feature flag systems, elastic scaling, and the observability stack required to operate a production SaaS product.
-
What engagement models do you offer for cloud projects?
We offer Dedicated Cloud Teams (for ongoing platform builds), Fixed-Scope Projects (for defined migration or development work), Managed Cloud Retainers (for 24/7 operations), and Cloud Advisory engagements (for architecture review and strategy).
-
Do you offer 24/7 managed cloud operations?
Yes. Our managed cloud service includes round-the-clock monitoring, incident detection and response, performance tuning, patch management, cost governance, and monthly business reviews - covering AWS, Azure, and GCP environments.
-
Can you work alongside our existing internal cloud team?
Yes - and this is one of our most common engagement patterns. Flexsin engineers embed with your internal team, filling capability gaps (architecture, security, DevOps) and transferring knowledge, rather than creating dependency.
-
How do you handle data security and IP protection?
We execute comprehensive NDAs and IP assignment agreements before any engagement begins. All code is maintained in client-owned repositories, access is role-restricted, and environments are isolated with full audit trails throughout the project lifecycle.
-
What DevOps tooling do you work with?
We work with GitHub Actions, GitLab CI/CD, Jenkins, ArgoCD, CircleCI for pipelines - Terraform, Pulumi, and CloudFormation for IaC - and Prometheus, Grafana, Datadog, and New Relic for observability. We adapt to your existing toolchain where needed.
-
