Modernization

Overview

Tekrosta Modernization helps organizations transform legacy systems into scalable, cloud-native, and future-ready architectures.

We focus on improving:

• Agility.
• Scalability.
• Performance.
• Cost efficiency.

👉 Goal: Move from legacy → modern → cloud-native

1. Infrastructure Modernization

What we provide

Transformation of traditional infrastructure into cloud-native, automated, and scalable environments.

Key capabilities

• Migration from on-prem to cloud: We move your servers and workloads from on-premises data centres into the cloud with minimal disruption.
• Defining cloud adoption roadmap: A phased plan sets out what moves, in what order and at what pace.
• Infrastructure as Code (IaC) adoption: Infrastructure is defined and managed through code, enabling fast, consistent, repeatable builds.
• Immutable infrastructure design: Servers are replaced rather than modified, preventing drift and making deployments predictable.
• Auto-scaling and high availability setup: Capacity adjusts automatically with demand, and services stay up even if components fail.
• Network and storage modernization: Legacy network and storage are replaced with cloud-native, scalable equivalents.

Outputs

• Cloud-ready infrastructure: A secure, well-designed foundation ready to host your workloads.
• Automated provisioning: New environments are created on demand through code rather than manual setup.
• Scalable environments: Environments that grow and shrink with business demand.

Business value

• Reduced operational overhead: Less time spent maintaining hardware and manual processes.
• Improved scalability and flexibility: You can respond quickly to changing demand.
• Faster environment provisioning: Environments are ready in a fraction of the time traditionally needed.

2. Containerization

What we provide

Packaging applications into containers for portability and consistency.

Key capabilities

• Application containerization (Docker): We package applications and their dependencies into containers that run the same way everywhere.
• Image optimization and security hardening: Container images are slimmed down and secured to reduce size, start-up time and attack surface.
• Container registry setup: A central, secure store for your container images with controlled access.
• Standardized runtime environments: Applications run in consistent, predefined environments across development and production.

Outputs

• Containerized applications: Your applications packaged and ready to run on any container platform.
• Portable workloads across environments: Workloads move easily between laptops, data centres and clouds.

Business value

• Environment consistency: Fewer "it worked in test" surprises.
• Faster deployments: Containers start quickly and deploy smoothly.
• Simplified dependency management: Everything an application needs travels with it.

3. Kubernetes & Managed Container Platforms

What we provide

Deployment and management of container orchestration platforms.

Platforms supported

• Amazon EKS.
• Amazon ECS.
• Azure AKS.
• Google GKE
• Self-managed Kubernetes

Key capabilities

• Cluster setup and configuration: We build Kubernetes clusters configured for security, reliability and your workload needs.
• Multi-cluster and multi-region design: Architectures spanning clusters and regions improve resilience and bring services closer to users.
• Autoscaling and workload scheduling: Kubernetes adds or removes capacity and places workloads efficiently according to demand.
• Networking (Ingress, service mesh): Traffic into and between services is routed, secured and observed in a controlled way.
• Security and RBAC setup: Role-based access and security controls limit who and what can do what within the cluster.

Outputs

• Production-ready Kubernetes platform: A hardened, tested platform ready for live applications.
• Scalable container orchestration: Orchestration that manages many containers as load grows.

Business value

• High scalability and resilience: Applications handle growth and recover from failures.
• Efficient resource utilization: Workloads are packed efficiently, reducing waste.
• Standardized deployment platform: Every team deploys in the same way.

4. Application Modernization

What we provide

Refactoring or re-architecting applications to align with cloud-native principles.

Approaches

• Rehost (minimal changes)
• Replatform (optimized for cloud)
• Refactor (microservices / cloud-native)

Key capabilities

• Monolith to microservices transformation: We break large applications into smaller, independent services that are easier to change and scale.
• API-first architecture: Services are designed around well-defined APIs, making integration and reuse easier.
• Integration with managed cloud services: Applications use managed databases, queues and other services, reducing operational work.
• Performance optimization: We tune applications to run faster and use fewer resources.

Outputs

• Modernized applications: Applications rebuilt or reshaped to run well in the cloud.
• Improved architecture and performance: A cleaner design that is faster, easier to maintain and ready to scale.

Business value

• Faster feature delivery: Smaller, independent components let teams release changes more often.
• Better scalability: Parts of the application scale individually as needed.
• Improved user experience: Faster, more reliable applications for your users.

5. Serverless & Event-Driven Architecture

What we provide

Adoption of serverless computing for highly scalable and cost-efficient workloads.

Key capabilities

• Function-as-a-Service (FaaS) implementation: Code runs only when triggered, with no servers to manage.
• Event-driven architecture design: Systems respond to events as they occur, keeping components loosely coupled and responsive.
• Integration with cloud-native services: Serverless functions work with storage, databases and messaging services.
• API Gateway and messaging systems: We set up managed gateways and queues to expose APIs and pass messages reliably.

Outputs

• Serverless applications: Applications built to scale automatically with minimal infrastructure.
• Event-driven workflows: Processes that react automatically to business events.

Business value

• Pay-per-use cost model: You pay only for the compute you use.
• Reduced infrastructure management: Less patching and less capacity planning.
• High scalability and agility: Applications handle spikes automatically and can be changed quickly.

6. Data & Database Modernization

What we provide

Modernization of legacy databases and data platforms.

Key capabilities

• Database migration (SQL/NoSQL): We move legacy databases to modern SQL or NoSQL platforms, with careful data validation.
• Managed database adoption: Managed database services take over patching, backups and failover.
• Data pipeline modernization: Older batch jobs are replaced with modern, automated pipelines.
• Caching and performance optimization: Caching and tuning cut query times and database load.

Business value

• Improved performance: Faster queries and responses.
• Scalability for data workloads: Databases grow with data volume and demand.
• Better analytics readiness: Modernised data is easier to analyse and use for AI.

7. Integration & API Modernization

What we provide

Modern integration patterns for legacy and new systems.

Key capabilities

• API Gateway implementation: A central entry point to manage, secure and monitor your APIs.
• Microservices communication patterns: Proven patterns let services talk to each other reliably.
• Event streaming (Kafka, Pub/Sub): Real-time event streams share data between systems as things happen.
• Legacy system integration: We connect older systems with modern applications without rewriting them overnight.

Business value

• Better system interoperability: Systems share data and work together smoothly.
• Faster integrations: Reusable patterns shorten the time needed to connect new systems.
• Scalable communication: Messaging and APIs grow with traffic.

8. DevOps Enablement for Modernization

Embedding CI/CD and automation into modernized systems.

Business value

• Continuous delivery of modern apps: Automated pipelines get updates to production steadily and safely.
• Faster innovation cycles: Teams can experiment and ship ideas more quickly.

9. Application Engineering & Code Modernization (Python & Golang)

What we provide

Modern application development and refactoring using cloud-native languages and architectures.

Key capabilities

• Microservices development (Python & Golang): We build lightweight, independent services in Python and Golang.
• API-first application design: Applications are designed around clean APIs from the beginning.
• Monolith to microservices transformation: We refactor existing code in stages, carving out services one at a time to manage risk.
