Cloud Application Modernization — Legacy Migration, Microservices & DevOps
Hurain Technologies has been engineering software since 2010 and delivers cloud application modernization development to businesses worldwide: remotely from India, available 24/7, on milestone-based scopes, with one project manager and full source-code ownership.
Scope typically covers assessment & roadmap, cloud migration and refactoring & microservices. A first production release usually takes 4–6 weeks (first workload live), and a full platform 3–12 months depending on estate. Every build is scoped against cloud security benchmarks (CIS) and data-residency and sovereignty rules.
Quick answer
What does Hurain Technologies build for cloud application modernization?
Hurain Technologies modernises legacy applications by migrating them to AWS, Azure or GCP, breaking monoliths into services where it pays off, containerising workloads, and adding CI/CD, observability and cost controls — incrementally, without a risky big-bang rewrite.

Overview
What cloud application modernization with Hurain Technologies looks like
Legacy systems usually still work — they are just slow to change, expensive to run and risky to touch. We modernise in slices using the strangler-fig pattern: new capabilities are built around the old system and traffic moves over gradually, so the business never stops.
Not everything needs microservices. We assess each component and choose rehost, replatform, refactor or replace based on business value, and we say so when a well-structured monolith is the better answer.
Every modernisation includes infrastructure-as-code, automated deployments, monitoring and a cloud-cost baseline, so the result is cheaper and safer to operate — not just newer.

Cost & timeline
How much does cloud application modernization cost and how long does it take?
Delivery time is agreed around your scope and split into milestones you sign off before paying. Price is driven by scope rather than a fixed rate card — these are the factors that move it most:
- Number and complexity of applications
- Database size and migration method
- Downtime tolerance
- Refactor vs rehost mix
- Compliance and data-residency
- Target operating model (managed vs in-house)

What Cloud Application Modernization does for your business
Benefits for your company
- Release faster, break less. Microservices, CI/CD and automated testing let teams ship weekly instead of quarterly, with safer rollbacks.
- Lower infrastructure bills. Right-sizing, autoscaling and cost monitoring on AWS, Azure or GCP remove paid-for idle capacity.
- Resilience and uptime. Redundancy, observability and tested recovery plans reduce downtime during peak demand.
How it can earn or save money
- Capture peak-demand revenue. Platforms that scale under load keep selling when competitors slow down or fail.
- Cut run costs. Retiring legacy hosting and licences reduces recurring spend you can reinvest in product.
- Faster new products. Shorter release cycles mean new features and pricing experiments reach customers sooner.
Illustrative revenue and saving lines, not guaranteed results: outcomes depend on your market, licences and execution.

Continuous enhancement
Launch is just the beginning — keep shipping with your own dedicated team
Your cloud application modernization platform should get better every month, not stand still after go-live. Start with one dedicated developer working on your priorities across apps, dashboards and backend — and grow to a full team of developers and support members whenever your roadmap demands it.
Dedicated team, your way
From one developer to a full team
Pricing is based on the team members you need — tell us your requirements and we will quote your team.
- Start any time after launch
- Hire developers as you need them
- Scale up, scale down or pause
What your team can take on after launch
- New environments, regions and services
- Deployment-pipeline and cost improvements
- Observability, scaling and resilience work
Need more hands? Add developers and support members as your requirements grow
Start with one person and add only the roles your cloud application modernization roadmap needs — each is quoted to your requirements.
Development team
DevOps engineer
Keeps pipelines, environments and deployments fast and reliable.
Cloud architect
Plans new regions, services and cost-efficient architecture.
Site-reliability engineer
Improves uptime, alerting and incident response.
Backend developer
Adds the APIs, business logic and data models behind new features.
Support team
L1 helpdesk support executive
First contact for your users and staff — logs, triages and resolves common issues.
L2 technical support engineer
Investigates bugs, data issues and integrations, and escalates to developers with full context.
24/7 NOC support engineer
Round-the-clock infrastructure monitoring and first response.
Site-reliability support
Handles incidents, post-mortems and capacity planning.
Our Approach
Our approach to development methodologies
Our approach to custom software engineering draws on a range of methodologies, each selected to match the needs of your cloud application modernization project.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so cloud application modernization priorities can change as you learn from users.
Kanban
Best for: Continuous delivery & support
A visual flow of small tasks with work-in-progress limits — ideal for maintenance, integrations and post-launch improvements.
Fixed-scope (Waterfall-style)
Best for: Well-specified builds
Requirements signed off up front with a fixed timeline and price — best when scope is clear and change is unlikely.
Lean MVP
Best for: New ventures
Build the smallest cloud application modernization release that proves demand, measure it with real users, then invest where the data points.
DevOps & CI/CD
Best for: Every project
Automated tests, infrastructure-as-code and push-button deployments so releases are frequent, reversible and boring.
Security-by-design (DevSecOps)
Best for: Regulated & high-value systems
Threat modelling, dependency scanning and code review built into each sprint rather than a pen test at the end.
Why we're different
What sets Hurain Technologies apart
Plenty of agencies can build cloud application modernization. Here is what sets us apart for clients worldwide.
Engineering depth, not a reseller
Your cloud application modernization project is designed and built by our own in-house engineers — no hidden subcontracting chain between you and the people writing code.
Built for your market, not a template
Payments, tax, language and data-protection requirements for your target market are part of the design from day one instead of retrofitted after launch.
Transparent, senior-led delivery
A named project lead, a shared backlog, fortnightly demos and direct Slack access to the engineers — you always know what is being built and why.
Cost advantage without cutting corners
Delivering from India gives clients worldwide senior engineering at a fraction of typical onshore agency rates, with the same code-review, testing and security standards.
You own everything
Source code lives in your repository from the first commit; IP, infrastructure accounts and documentation transfer to you in full.
We stay after launch
Monitoring, updates and a support SLA mean the team that built your product is the team that keeps it running.
Flexible engagement models
