The Challenge

Legacy Applications Shouldn't Hold Your Business Back

Many organizations rely on legacy applications to run critical operations. While these systems continue to support the business, they often become harder to maintain, update, and scale as technology evolves. Modernizing your applications helps improve performance, strengthen security, and make future development faster and more efficient.

  • Legacy applications that are difficult to scale.
  • Slow release cycles that delay innovation.
  • Security and compliance that slow every deployment.
  • Outdated infrastructure that's expensive to maintain.
How We Work

A Proven Process for Every Project

01

Assess

We evaluate your application portfolio, architecture, dependencies, and deployment processes. Our team identifies which applications should be modernized, optimized, replaced, or retired, giving you a clear roadmap for the next steps.

02

Design

Working closely with your engineering team, we design a modern application architecture that fits your business goals. From containers and microservices to data migration and security, every decision supports long-term reliability and compliance.

03

Build

We modernize applications in carefully planned phases to reduce risk and maintain business continuity. Every update is tested, validated, and deployed before moving to the next stage of the project.

04

Scale & Operate

After deployment, we help your team manage and optimize the application with monitoring, documentation, automation, and ongoing technical support. If preferred, we can also provide long-term managed services for your environment.

What We Do

Application Modernization Capabilities

Cloud Application Modernization

Modernize your applications with an approach that fits your business goals. Whether you choose to rehost, replatform, refactor, or rebuild, we help you improve performance, scalability, security, and long-term maintainability.

Containerisation & Orchestration

Package applications with Docker and manage them using Kubernetes across on-premises, AWS, Azure, or Google Cloud. We build consistent environments that simplify deployments and improve application reliability.

Modern CI/CD Pipelines

Automate your software delivery with reliable CI/CD pipelines that build, test, validate, and deploy applications consistently. This helps your teams release updates faster while improving quality and reducing manual effort.

Microservices Architecture

Break large applications into smaller, independent services that are easier to develop, deploy, and maintain. This approach improves scalability, simplifies updates, and gives development teams greater flexibility.

Secure Software Development

Build security into every stage of the development process. We perform automated security testing, code reviews, vulnerability scanning, and policy validation to help deliver secure and reliable applications.

Continuous Security & Compliance

Protect your applications with continuous monitoring, vulnerability assessments, compliance reporting, and proactive security management. We help organizations meet industry standards while maintaining a strong security posture.

The right approach depends on your application's current condition and business goals. Tek Yantra starts with a detailed assessment to evaluate your architecture, performance, security, and long-term requirements. Based on our findings, we'll recommend whether modernization, rebuilding, or replacing the application is the best path forward.

No. Kubernetes is a great fit for many applications, but it's not the only option. We recommend the platform that best supports your application's performance, scalability, and operational requirements, whether that's Kubernetes, containers, virtual machines, or managed cloud services.

Project timelines depend on the size, complexity, and number of applications involved. After reviewing your environment, we'll create a project plan with clear milestones, realistic timelines, and a phased implementation approach that minimizes business disruption.

The cost varies based on your application portfolio, technical complexity, and project scope. Once we understand your requirements, we'll provide a transparent proposal with a detailed scope of work and pricing.

In many cases, yes. We use proven migration and deployment strategies to minimize downtime and reduce operational risk. Before any work begins, we'll discuss the migration approach and any expected service interruptions.

Yes. We help organizations modernize applications while supporting compliance requirements such as FedRAMP, HIPAA, SOC 2, FISMA, and CMMC. Security and compliance are considered throughout every stage of the project.

Absolutely. We work closely with your developers, architects, and IT teams throughout the project. Our collaborative approach ensures knowledge sharing, smooth implementation, and a seamless transition after delivery.

Yes. If your modernization project has slowed down or encountered technical challenges, our engineers can assess the current environment, identify the issues, and recommend practical solutions to get the project moving forward.
