In monolithic architecture, all the components are tied up together, so if you need to scale one feature, you have to expand the entire system.
Even if you need to implement minor adjustments, it leads to full redeployment and retesting.
Legacy maintenance cost and complexity rise with each release.
Because of large shared codebases, multiple teams can’t work on different features independently.
Integration of modern tools, cloud services, and APIs is blocked by outdated frameworks.
We specialize in converting monolithic applications to microservices, being a reliable partner for businesses in their modernization journey since 2007. With strong adherence to compliance, security, and business goals, we became a part of 100+ client success stories.

Let us help you rebuild what’s holding you back.
Refactoring a monolith to microservices by Corsac is aimed at removing tech debt and low-risk transformation for continuous growth.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
In legacy systems, decision logic is locked inside monoliths, making AI integration risky. We perform monolith to microservices migration to decompose services, making logic and data movement explicit. This enables AI to augment decisions in a controlled, observable way.
Monolithic architectures may allow uncontrolled data access and implicit behavior, compromising AI reliability. Monolithic to microservices migration strategy implements clear ownership, contracts, and data boundaries to prevent silent data drift and ensure reliable AI results.
Integrated into unprepared monoliths, AI can trigger risks. Monolithic to microservices migration introduces APIs and event-based architecture, enabling parallel operation of AI and core workflows. This facilitates experimentation, rollback, and controlled releases, without impeding continuity.
Traceability and accountability are limited in monoliths. By migrating to microservices with inherent observability and versioning, we make AI actions explainable, auditable, and materially reduce risk in regulated use cases.
Instead of rewriting the monolith completely, we extract frequently modified business domains, including billing, pricing, workflows, and reporting, into modular services. This path from monolithic application to microservices secures the core platform and enables reliable modernization and AI adoption.
We break the dependency on a single shared database by moving from monolithic database logic to service-managed data access with controllable APIs. This eliminates hidden coupling, expedites deliveries, prevents unexpected side effects, and prepares data for smooth AI function.
We start breaking monolith to microservices by identifying the primary sources of regression: UI logic, integrations, and fast-changing rules. They are the first to go into independent services, which enables safe updates without redeploying the entire system.
We surround the monolith with integration and automation services to avoid the risks of altering internal parts. Legacy systems remain stable while cloud platforms, data pipelines, and AI can freely interact through clear and controlled boundaries.
When replacement is not viable, we apply hybrid coexistence. In critical business systems, we introduce microservices incrementally, while the monolith is still operating. Thus, we prevent cutovers and ensure uninterrupted operations, production safety, and reversible changes.
We thoroughly evaluate each part of your system, uncovering weak spots and dependencies in architecture, codebase, integrations, etc. After identifying potential risks and growth opportunities, we build a KPI-based migration roadmap aligned with your core goals.
We re-architect your outdated system based on domain standards and your business logic, as well as identify microservices contracts and data strategies. Before being separated, each microservice is thoroughly assessed for reliability and scalability.
A phased approach to refactoring and containerization helps us minimize disruption and ensure stable processes.
Deployment and rollback security at any stage are enabled via CI/СD tools, automated testing, and continuous monitoring.
We use Kubernetes for orchestration that significantly enhances deployments and performance both in cloud and hybrid environments (AWS, Azure, GCP, or private clusters).
Each iteration includes security and performance assessments alongside verification of GDPR or HIPAA compliance.
We take care of process transparency by handling regular demos and synchronization with your core operations.
After deployment, we monitor each microservice. Thanks to DevOps tools, logging, and advanced analytics, we’re enabled to catch any anomaly fast and deliver necessary fixes or optimizations.

Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
Monolith to microservices migration is a must if your business struggles with scalability and your tech debt affects overall performance and teamwork. By dividing architectures into individual components, you can reduce operational risks, deliver changes or new features quickly, simplify team collaboration, and adopt new technologies to innovate and stay compatible.
First, we conduct root-cause analysis to identify true reasons for your tech debt, hidden dependencies, risks, existing infrastructure, and growth opportunities. Based on this, we create a monolithic to microservices migration strategy with deadlines and KPIs. Success is tracked by the achievement of measurable goals at each milestone. Post-migration, we assess improvements in system scalability, stability, maintainability, release velocity, compliance, etc.
Migration from monolith to microservices makes your system more flexible and efficient. Here are just several benefits that can help optimize costs: seamless maintenance, faster deployment process, smooth integration with external tools and systems, ability to opt for modern technologies without significant limitations.
In the long run, all the mentioned benefits will enable you to allocate project resources smarter and achieve business goals with less effort.
In Corsac, we practice phased moving from monolith to microservices. We define key priorities and build a clear plan of what system parts should be modernized first. Such an approach significantly cuts risks of workflow disruption and enables safe testing, deployment, and rollbacks (if necessary) without affecting overall stability. Your system stays fully operational while we validate each service independently.
Yes. After migration of the monolithic application to microservices, we carefully track system performance, using dashboards, logging, and advanced analytics. This way, we can detect potential issues as fast as possible and take necessary measures without disrupting system stability and efficiency.
