Posted on October 17, 2025
Moving to the cloud isn’t just a tech project—it’s a business transformation. Done well, it speeds up releases, improves reliability, cuts costs, and gives your teams modern tools. Done poorly, it can cause downtime, security headaches, and surprise bills. That’s why many organizations turn to a cloud migration service provider: a partner who brings proven methods, skilled engineers, and guardrails so your move is safe, predictable, and fast.
In this guide, we’ll explain what cloud migration service provider do, how to choose one, what a typical migration looks like, and where Tek Yantra fits in as a hands-on, reliability-first partner.
What Does a Cloud Migration Service Provider Do?
A cloud migration service provider helps you plan, move, and modernize workloads from on-premises data centers (or between clouds) into platforms like AWS, Azure, and Google Cloud. The best providers do more than lift-and-shift. They:
- Assess your current environment
- Inventory servers, apps, databases, data flows, and dependencies
- Identify quick wins and high-risk areas
- Estimate cost, time, risks, and resource needs
- Design a landing zone and architecture
- Secure-by-default cloud accounts, networks, IAM roles, and guardrails
- Decide what to rehost, replatform, refactor, or retire
- Map resilience, backup, disaster recovery (DR), and observability
- Migrate workloads safely
- Set up migration tooling and automation
- Move data with minimal downtime
- Cut over services in phases, with rollback plans
- Modernize for value (not just relocation)
- Containerize apps, add CI/CD, introduce autoscaling
- Replace legacy components with managed cloud services where it makes sense
- Tune for performance, cost, and security
- Operate and optimize after go-live
- SRE runbooks, 24/7 monitoring, alerting, incident response
- Ongoing cost controls and rightsizing
- Compliance reporting and periodic posture reviews
Tek Yantra delivers all five, with a strong focus on site reliability engineering (SRE) and multi-cloud resilience—keeping services stable during peak traffic or third-party incidents.
Why Organizations Bring in a Provider (Instead of Going Solo)
- Speed and predictability: Experienced teams avoid dead ends and time sinks.
- Risk reduction: Repeatable patterns, battle-tested runbooks, and rollback plans.
- Security and compliance by design: IAM, encryption, network segmentation, and audit logs built in from day one.
- Cost control from the start: Architecture and tagging that make FinOps possible, not an afterthought.
- Knowledge transfer: Your staff learns modern cloud and DevOps practices from the provider’s engineers.
Tek Yantra emphasizes “resilience first”: multi-cloud architectures, chaos testing, and DR drills so that uptime and trust are protected.
Cloud Migration Strategies (the “6 Rs” in Simple Terms)
Cloud migration isn’t one-size-fits-all. Providers help you choose the right approach for each app:
- Rehost (Lift-and-Shift)
Move as-is to cloud VMs. Fastest path, least change. Limited optimization. - Replatform (Lift, Tinker, Shift)
Minor changes to use cloud services (managed databases, load balancers). Good balance of speed and improvement. - Refactor (Re-architect)
Redesign app components—containers, serverless, event-driven. Higher effort, but big gains in speed, cost, and reliability. - Repurchase (SaaS)
Replace an app with a SaaS product (e.g., CRM, analytics). Quick win if features match needs. - Retire
Turn off unused systems. Reduces costs and complexity. - Retain
Keep some systems on-prem for now due to compliance, latency, or cost.
Tek Yantra often blends these: quick rehosts for low-risk services, replatform key databases, and refactor high-value apps to containers or serverless where the ROI is clear.
A Practical Migration Roadmap
Below is a step-by-step journey you can expect with a capable provider like Tek Yantra. The language is plain; the work is rigorous.
Phase 1: Discover & Assess
- Inventory apps, databases, storage, integrations, and SLAs.
- Build dependency maps (what talks to what).
- Score each workload on complexity, risk, and business criticality.
- Draft the business case: cost estimates, expected downtime, benefits.
Tek Yantra add: early SRE assessment (SLOs, error budgets), security posture review (IAM sprawl, network exposure), and cost hygiene (unused resources).
Phase 2: Cloud Foundations (Landing Zone)
- Set up accounts/subscriptions with guardrails: baseline IAM, VPC/VNet, subnets, routing, private links, security groups/NSGs.
- Logging and observability centralization.
- Secrets management, backup policies, encryption standards.
- Golden images or base container images.
- Tagging strategy for FinOps and compliance.
Tek Yantra add: reference architectures for multi-cloud failover, automated policy enforcement (OPA/Policy-as-Code), and change control via GitOps.
Phase 3: Migration Wave Planning
- Group workloads into waves by dependency, risk, and business calendar.
- Define “done” (acceptance criteria), rollback paths, and maintenance windows.
- Set DR and RTO/RPO targets per workload.
Tek Yantra add: cutover playbooks, chaos test scenarios, and stakeholder comms templates to reduce surprises.
Phase 4: Execute the Moves
- Stand up staging environments.
- Sync data (continuous replication or scheduled cutovers).
- Performance test in cloud.
- Security validation: vulnerability scans, IAM least privilege.
- Final cutover with monitoring on and business signoff.
Tek Yantra add: SRE on call during cutover, real-time dashboards, and a hard rollback switch if KPIs turn red.
Phase 5: Stabilize & Optimize
- Post-migration tuning: rightsizing, reserved capacity, autoscaling thresholds.
- Incident reviews and runbook updates.
- Cost visibility for teams; budget alerts and reports.
- Roadmap for refactor/modernization phases that deliver further savings and speed.
Tek Yantra add: monthly resilience drills, DR tests, and “cost + reliability” scorecards for leadership.
Security & Compliance: Build It In, Not On
A strong provider treats security as a default, not an extra. Key practices include:
- Identity and access management (IAM): least privilege, short-lived credentials, SSO.
- Network controls: private networking, zero trust patterns, WAF, DDoS protections.
- Data protection: encryption at rest/in transit, key rotation, secrets vaulting.
- Governance & policy: Policy-as-Code to block noncompliant changes automatically.
- Observability: centralized logs, metrics, traces with alert hygiene to cut noise.
- Compliance tooling: mapping to frameworks (e.g., NIST 800-53, ISO 27001, SOC 2), audit-ready evidence trails.
Tek Yantra integrates these from day one and pairs them with SRE playbooks for rapid incident response and measurable uptime.
Cost Control (FinOps) Without Guesswork
Cloud costs can creep up fast—especially during and after migration. Providers with FinOps experience help you avoid surprises:
- Right-size instances and storage; avoid over-provisioning.
- Use the right pricing models: reserved instances/commitments and autoscaling.
- Turn off dev/test resources when not in use.
- Set budgets and alerts at the team/project level.
- Tag everything to trace spend to owners and outcomes.
- Review monthly: cut waste, renegotiate where possible, and forecast.
Tek Yantra bakes cost visibility into CI/CD and governance so engineers see spend signals as they build—not months later.
What “Good” Looks Like After Migration
When a migration is done well, you’ll notice:
- Faster releases: CI/CD pipelines, infrastructure as code, and quick rollbacks.
- Higher reliability: autoscaling, managed services, multi-AZ/region options.
- Better security posture: less shadow IT, clear policies, fewer ad-hoc exceptions.
- Lower toil: teams focus on features and customers, not server babysitting.
- Predictable costs: fewer surprises, cleaner chargebacks, ongoing optimization.
These are the outcomes Tek Yantra optimizes for, especially in public-sector and high-traffic enterprise environments.
Choosing the Right Cloud Migration Partner
Here’s a simple checklist to evaluate providers (including Tek Yantra):
- Proven playbooks: Ask for their migration methodology, sample runbooks, and rollback procedures.
- Security-first approach: Do they embed IAM, encryption, and Policy-as-Code in foundations?
- SRE capability: Can they define SLOs, build dashboards, and run incident response?
- Modernization chops: Containers, serverless, data platforms, and managed services—real experience, not buzzwords.
- Multi-cloud realism: Can they design for cross-cloud resilience without unnecessary complexity?
- Compliance experience: Familiar with your frameworks and able to produce audit-ready evidence.
- FinOps rigor: Tagging strategy, budget alerts, rightsizing, and governance from day one.
- Change management: Stakeholder comms, training, and knowledge transfer to your teams.
- References & case stories: Request relevant examples. For Tek Yantra, this often includes high-uptime public portals and zero-downtime migrations.
- Cultural fit: Do they collaborate well with your engineers and adapt to your reality?
A Mini Case Story (Illustrative)
A state agency had a legacy web portal with unpredictable traffic spikes. Releases were slow, outages frequent, and audits painful. They engaged Tek Yantra to migrate to a multi-region cloud architecture.
- Assessment: Found tightly coupled services and manual deployments.
- Foundations: Built a secure landing zone with centralized logging, IAM least privilege, and Policy-as-Code.
- Migration: Rehosted the front-end quickly, replatformed databases to managed services, and refactored the API to containers.
- Cutover: Executed in phases with SRE on call, live dashboards, and validated rollback plans.
- After: 99.99%+ uptime, autoscaling during surges, CI/CD for weekly releases, and audit-ready reports. Costs became predictable with tagging and budgets.
This kind of result is typical when the process, people, and culture align—something Tek Yantra emphasizes from day one.
Common Pitfalls (and How Providers Avoid Them)
- Moving everything at once: Leads to chaos. Instead, use waves and clear acceptance criteria.
- Skipping dependency mapping: Causes “moved app can’t find its database” moments.
- Underestimating data migration: Plan for replication, cutovers, and verification.
- Ignoring operations: If SRE/observability is an afterthought, problems multiply post-go-live.
- No cost governance: Bills balloon without tagging, budgets, and rightsizing.
A partner like Tek Yantra makes these risks explicit and addresses them early.
Tooling You’ll Likely See
- IaC: Terraform, CloudFormation, Bicep for reproducible environments
- Containers & Orchestration: Docker, Kubernetes, ECS/EKS/AKS/GKE
- CI/CD: GitHub Actions, GitLab CI, Azure DevOps, Jenkins
- Observability: Cloud-native logging/metrics/tracing, OpenTelemetry, alert routing
- Security: IAM policies, OPA/Conftest, secret managers, WAF, vulnerability scanners

Tek Yantra selects tools to match your stack, not the other way around.
How to Prep Internally Before You Engage a Provider
- Define goals: faster releases, lower costs, compliance, reliability targets.
- Prioritize apps: what’s critical, what can wait, what can retire.
- Assign owners: business, product, and technical owners for each workload.
- Collect docs: architecture diagrams, runbooks, access lists, SLAs.
- Clarify timelines: busy seasons, release windows, maintenance windows.
- Decide success metrics: SLOs, cost targets, deployment frequency.
Showing up organized lets your provider—Tek Yantra or anyone—move faster and with less risk.
