Applicationrefactoring
Disruption Consulting rebuilds applications from the ground up. Deep discovery and broad domain knowledge produce cloud-native architectures that take genuine advantage of ephemeral compute and auto-scaling, and that spare organizations the runaway budgets of shifting workloads to the cloud without rethinking them.
Why lift-and-shift fails
The most common cloud migration mistake is treating cloud infrastructure as a different place to run the same applications the same way. The result is predictable: cost grows, complexity increases, and the promised benefits never materialize.
Cloud spend out of control
Applications ported to the cloud without refactoring carry the over-provisioning habits of on-premises, paying for peak capacity around the clock instead of scaling with demand.
Long-running workloads
Batch jobs and scheduled processes designed for mainframes run continuously on cloud virtual machines, accumulating cost that dwarfs what the original hardware needed.
SaaS sprawl
Replacing mainframe functionality with several SaaS products shifts spend without reducing it, and often adds integration complexity and licensing cost on top.
Disruption Consulting does not do lift-and-shift. We refactor applications into cloud-native architectures designed for the economics and the capabilities of the cloud from day one.
How we approach refactoring
From legacy mainframes to monolithic enterprise applications, we have the expertise to rebuild what organizations depend on, better, faster and cheaper than the systems it replaces.
Deep discovery before a line of code
Every refactoring engagement starts with broad, structured discovery: not just what the application does, but why it was built that way, which business processes depend on it, and where the real cost and risk sit. That prevents the common failure mode of refactoring the wrong things, and keeps the new architecture tied to the actual business requirements.
Cloud-native by design, not by accident
A lift-and-shift migration moves cost from hardware to a cloud provider without delivering any of the benefits that make cloud computing valuable. We refactor applications to be genuinely cloud-native: decomposed into services that scale independently, running on ephemeral compute, using managed data services, and priced for actual consumption rather than peak provisioning.
Serverless and auto-scaling architectures
The most powerful thing cloud computing offers is a workload that scales to zero when idle and to thousands of instances under load, with no manual intervention and no over-provisioned capacity. We design refactored applications to exploit that fully, removing the long-running workloads and idle compute that quietly destroy cloud economics.
Mainframe and mid-frame to x86
Legacy mainframe and mid-frame workloads present a specific challenge: they cannot move directly to cloud-native infrastructure without first migrating to x86. We have proven experience making that transition, converting mainframe workloads to x86 as the foundation step that unlocks the cloud migration that follows.
Enterprise security, extended to the cloud
Refactored applications do not exist in isolation. Every cloud-native application we build is designed to integrate with the enterprise security controls, identity infrastructure and compliance frameworks the organization already runs.
The result is a cloud application that is not a security exception. It is a full participant in the enterprise security posture, with single sign-on, auditing, monitoring and access controls that satisfy the compliance, risk and security operations teams.
- Single sign-on and federated identity through SAML, OIDC and OAuth 2.0
- Enterprise security control extension: existing SIEM, EDR and DLP policies applied to cloud workloads
- Regulatory audit logging with immutable, tamper-evident records for compliance frameworks
- Role-based access controls enforced at the application, API and infrastructure layers
- Network security group and firewall policies consistent with the on-premises posture
- Automated compliance monitoring and alerting integrated with existing security operations
Single sign-on and federated identity
Every refactored application is integrated with the identity provider you already use, whether Microsoft Entra ID, Okta or an on-premises directory, so people authenticate once and access follows them across cloud and on-premises systems without separate credentials or extra access management overhead.
Regulatory auditing built in
Compliance requirements do not stop at the cloud boundary. We design immutable audit trails, automated compliance monitoring and regulatory reporting into every cloud-native application from the start, rather than retrofitting them when an audit demands it.
Enterprise integration
New cloud-native applications integrate with the enterprise systems already in place, including ERP, CRM, data platforms and on-premises services, through secure, well documented APIs that keep the wider estate consistent.
