Klika Tech Legacy Code & Runtime Modernization

Klika Tech Legacy Code & Runtime Modernization is a professional services offering for organizations whose application portfolios are constrained by unsupported runtimes, outdated frameworks, vulnerable dependencies, obsolete libraries, or accumulated technical debt. These issues increase security exposure, delay feature delivery, complicate cloud migration, and consume engineering capacity that could otherwise support new business capabilities. Klika Tech runs modernization as a planned engineering program with dedicated analysis, prioritization, execution, and review. The offering can be purchased independently, used to address blockers identified during a migration assessment, or delivered as a specialized workstream within a broader AWS migration and modernization program.

The engagement begins with automated codebase analysis and engineer-led review across the customer’s application portfolio. Klika Tech documents architecture, business logic, dependencies, known vulnerabilities, end-of-life exposure, upgrade relationships, and the operational risk of taking no action. These findings are consolidated into a prioritized roadmap that customers can review, budget, and schedule. Each modernization pattern is then defined with clear scope, protected behavior, build and test commands, and measurable validation criteria. Klika Tech pilots the transformation on a representative repository, incorporates lessons from the pilot, and rolls the approved pattern across additional codebases. Changes are committed separately and merged only after review through the customer’s established development and governance processes. Modernization may include Java, Python, Node.js, TypeScript, and AWS Lambda runtime upgrades; AWS SDK migrations; Spring Boot, React, and Angular upgrades; dependency and internal-library replacement; observability improvements; x86-to-AWS-Graviton transitions; server-to-container modernization; and Infrastructure as Code translations.

AWS Transform custom is used where agentic automation can reduce the cost of repetitive, well-defined transformation work across multiple repositories. Klika Tech engineers define and refine the transformation patterns, review generated changes, capture lessons from each execution, and apply those improvements to subsequent repositories. Engineering judgment, architecture decisions, validation, and delivery accountability remain with Klika Tech and the customer’s designated reviewers. Customers receive a documented portfolio, a maintained modernization roadmap, updated code and runtime components within the agreed scope, and reusable transformation definitions for future upgrade cycles. Depending on customer requirements, this offering relates to AWS Transform custom, AWS Lambda, AWS SDKs, Amazon EC2 with AWS Graviton processors, Amazon ECS, Amazon EKS, AWS CDK, and related AWS services. Deliverables remain in the customer’s AWS account and source-code repositories. AWS service consumption and infrastructure charges are billed separately by AWS.
