Cloud Application Modernization & DevOps Engineering
Legacy monoliths slow every release and every hire. Hurain Technologies modernizes applications and infrastructure for enterprises that need to move faster without breaking what already works — monolith-to-microservices migration, cloud-native re-architecture, and DevOps automation that shortens release cycles from weeks to days.
Quick answer
Do we need to rewrite our entire application to modernize it?
No. We use incremental strangler-fig migration patterns that modernize piece by piece without a risky full rewrite. Founder Shahnavaz Syed leads a DBA team, development team and hosting team with 15+ years of experience each, so your cloud modernization project is designed, built and hosted by the same accountable group. Pricing starts at US$20–40 per hour; final charges and timeline are set after we confirm your requirements, and depend on your budget and the team members assigned to the project.

Overview
What cloud modernization & devops engineering actually involves
Modernization projects fail most often not because the target architecture was wrong, but because the migration path from the current system to that target was too risky to actually execute — a big-bang rewrite that has to be perfect on day one, or a lift-and-shift that moves the same tightly coupled problems into a more expensive environment. The strangler-fig pattern we default to avoids both failure modes: new functionality is built as independent services alongside the existing monolith, traffic is incrementally routed to the new services as they prove themselves, and the legacy system shrinks piece by piece until there's nothing left to strangle — with a working, deployable system at every single step along the way, not just at the end.
The DevOps side of modernization is just as important as the architecture, because a well-decomposed system with a manual, error-prone deployment process just moves the bottleneck from code review to release day. CI/CD automation, infrastructure-as-code, and observability aren't a separate project bolted on afterward — we build them alongside the architecture so that the moment a service is ready, it can actually ship safely and be monitored in production.
The Challenge
Problems we see teams struggling with
Slow, risky releases
Monolithic architecture means every deployment is high-risk and requires full regression testing.
Rising cloud costs without visibility
Lift-and-shift migrations often increase cost without improving performance or scalability.
Scaling bottlenecks under load
Tightly coupled systems can't scale individual components independently during demand spikes.
Manual, inconsistent deployments
Without CI/CD automation, releases depend on manual steps prone to human error.
Vendor and framework lock-in
Legacy systems built tightly around a specific vendor's proprietary tooling become expensive and risky to migrate away from even when the business need clearly justifies it.
No observability into production failures
Without distributed tracing and centralized logging, diagnosing a failure in a microservices environment can take hours instead of minutes.
Our Approach
How Hurain Technologies solves it
Monolith-to-microservices migration
Incremental decomposition using strangler-fig patterns that modernize without a risky big-bang rewrite.
Cloud-native application development
Containerized, horizontally scalable applications built for AWS, Azure, or GCP from the ground up.
DevOps & CI/CD automation
Automated build, test, and deployment pipelines that cut release cycles from weeks to days.
Kubernetes & container orchestration
Production-grade Kubernetes clusters with autoscaling, service mesh, and observability built in.
Cloud cost & performance optimization
Right-sizing, reserved capacity planning, and architecture tuning that cuts cloud spend without sacrificing performance.
Modernization assessment & roadmap
A prioritized, risk-ranked roadmap for legacy systems before a single line of code changes.
Observability and incident response tooling
Distributed tracing, centralized logging, and alerting built in from day one, so production issues are diagnosed in minutes rather than hours.
Technology
Tech stack we work with
Cloud Platforms
Containers & Orchestration
CI/CD
Observability
Service boundaries are the single most consequential decision in a decomposition project, and getting them wrong is expensive to undo later. We draw boundaries around business capabilities and data ownership rather than technical layers — a 'payments' service that owns its own data and logic end-to-end, not a 'database layer' service that every other service depends on synchronously. This keeps services independently deployable, which is the entire point of the exercise; a microservices architecture where every deployment still requires coordinating five other teams has all the operational cost of microservices with none of the benefit.
Cost optimization is a genuine engineering discipline, not just a billing review: right-sizing instances against actual observed load, moving predictable workloads to reserved or committed-use pricing, and — often the biggest lever — fixing architectural inefficiencies (chatty service-to-service calls, unnecessarily duplicated data, over-provisioned autoscaling thresholds) that no amount of instance-size tuning will fix on its own.
Use Cases
Where cloud modernization & devops engineering gets used
Legacy monolith decomposition
Breaking apart a large, tightly coupled application into independently deployable services without a risky big-bang rewrite.
Cloud migration from on-premise
Moving on-premise infrastructure to AWS, Azure, or GCP with a re-architecture pass, not just a lift-and-shift that carries the same limitations into a more expensive environment.
CI/CD pipeline buildout
Automated build, test, and deployment pipelines for teams still relying on manual, error-prone release processes.
Kubernetes platform engineering
Production-grade cluster architecture with autoscaling, service mesh, and observability for teams containerizing for the first time or outgrowing a basic setup.
Cloud cost optimization audits
A focused review of existing cloud spend that identifies right-sizing, reserved capacity, and architectural fixes without requiring a full modernization project.
Multi-region and disaster recovery architecture
Designing for regional failover and business continuity for systems that have outgrown a single-region deployment.
Proof
Results we've delivered
Client Result
An enterprise fintech client was deploying once every three weeks due to monolith risk. Hurain Technologies decomposed the core platform into 14 microservices with a full CI/CD pipeline, taking them to multiple deployments per day while cutting cloud infrastructure cost by 28%.
Process
How an engagement runs
- 1
Modernization assessment
We audit the current architecture and produce a prioritized, risk-ranked modernization roadmap.
- 2
Target architecture design
Microservices boundaries, data ownership, and cloud architecture defined before migration begins.
- 3
Incremental migration
Strangler-fig migration pattern moves functionality without a disruptive rewrite.
- 4
CI/CD & observability rollout
Automated pipelines and monitoring deployed alongside the new architecture.
- 5
Optimization & handover
Performance tuning, cost optimization, and documentation handed to your internal engineering team.
Engagement Models
How we structure the work
Modernization assessment
A 2-4 week audit producing a prioritized, risk-ranked roadmap — the standard starting point before any migration work begins.
Dedicated migration pod
A senior engineering team embedded with your organization for the 3-9 month duration of a full modernization project.
CI/CD and DevOps sprint
A focused engagement to build out automated pipelines and observability tooling, independent of a larger architectural migration.
Ongoing platform engineering retainer
Continued infrastructure and DevOps support once the modernization is complete, for teams that want to keep evolving the platform.
Pitfalls
Mistakes we see teams make
Decomposing by technical layer instead of business capability
Splitting a monolith into a 'database service' and a 'logic service' instead of business-aligned services recreates the same coupling problems in a more complex, distributed form.
Migrating without an observability plan
Moving to microservices without distributed tracing and centralized logging means production incidents that used to take minutes to diagnose can now take hours.
Lift-and-shift without re-architecting
Moving a monolith's exact architecture into the cloud unchanged usually increases cost without improving the scalability or reliability problems that motivated the migration.
Skipping the strangler-fig incremental approach
Attempting a full rewrite in parallel with the legacy system risks both systems falling out of sync and a launch that has to be perfect on day one.
Glossary
Key terms explained
- Strangler-fig pattern
- An incremental migration approach where new functionality is built alongside a legacy system and traffic is gradually routed to it, until the legacy system can be safely retired.
- Microservices
- An architectural style where an application is composed of small, independently deployable services, each owning its own data and business logic.
- CI/CD
- Continuous Integration/Continuous Deployment — automated pipelines that build, test, and deploy code changes, reducing manual release risk.
- Service mesh
- Infrastructure layer (like Istio) that handles service-to-service communication concerns — retries, encryption, observability — outside of application code.
- Observability
- The combination of logging, metrics, and distributed tracing that lets a team understand what's happening inside a running system, especially during an incident.

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 modernization project.
Agile Scrum
Best for: Evolving products
Two-week sprints with a working demo at the end of each, so cloud 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 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.
