Migration of On-Premise Infrastructure to AWS (Lift-and-Shift Approach)

Client : Lift and Shift Migration

Client Overview

Client Name: Lift and Shift Migration
Industry: IT Infrastructure Services
Project Title: Migration of On-Premise Infrastructure to AWS (Lift-and-Shift Approach)

Lift and Shift Migration is a technology-focused client keen on modernizing their IT infrastructure to take advantage of the flexibility and scalability offered by cloud services. The client’s primary objective was to maintain operational continuity while enhancing their capability to adapt to future demands.

Business Challenges

The client faced substantial challenges with their existing on-premise infrastructure, including:

  • Legacy Hardware Dependency: Outdated physical servers increased maintenance costs and hindered performance.
  • Limited Scalability: The existing infrastructure could not easily accommodate fluctuations in demand, leading to potential bottlenecks.
  • Slow Deployment Cycles: Time-consuming and labor-intensive deployment processes slowed time-to-market for new applications and features.
  • Operational Risk: The migration to a modern infrastructure was imperative but carried the risk of significant downtime.

Technology Stack

To address these challenges, the following technologies and tools were employed:

  • Cloud Services: Amazon Web Services (AWS) – EC2, S3, VPC, IAM, CloudWatch, RDS
  • Containerization and Orchestration: OpenShift Container Platform (OCP), Docker, Kubernetes
  • Automation and Configuration Management: Jenkins, Ansible, Terraform
  • Version Control: Git, GitHub
  • Monitoring: Prometheus, Grafana
  • Operating Systems: Linux

Solution Approach

The project leveraged a Lift-and-Shift strategy for the migration, which included:

  1. Assessment: Comprehensive evaluation of existing on-premise servers and applications.
  2. Planning: Development of a detailed migration plan to minimize risks and downtime.
  3. Execution:
    • Server and Application Migration: Transitioning over 100 servers and applications to AWS infrastructure.
    • Containerization: Encapsulating applications within containers using OpenShift, ensuring high availability.
    • Automation: Setting up CI/CD pipelines with Jenkins and Terraform to streamline deployment processes.

Solutions Delivered

Key solutions included:

  • Migration: Successful migration of 100+ on-premise servers and applications to AWS, ensuring near-zero downtime.
  • Application Deployment: Deployed applications on OpenShift Container Platform to enhance scalability and availability.
  • CI/CD Automation: Implementation of automated CI/CD pipelines for quicker cloud deployments.
  • Infrastructure Security: Strengthened AWS IAM policies, VPC configurations, and established alerts through CloudWatch for robust monitoring.
  • Performance Optimization: Conducted thorough post-migration performance tuning and cost-saving assessments.

Key Benefits

The migration brought several significant advantages:

  • Seamless Migration: The transition occurred without any disruption to daily business operations.
  • Enhanced Scalability and Flexibility: Leveraging AWS cloud infrastructure facilitated instant scaling according to demand.
  • Improved Security and Compliance: Strengthened security measures met compliance requirements effectively.
  • Cost Reduction: Infrastructure maintenance costs reduced by 35%, allowing funds to be reinvested into innovation.
  • Accelerated Deployment: Enabled faster application deployments using OpenShift and CI/CD automation.

Project Outcomes

The migration project was a resounding success, yielding the following outcomes:

  • Operational Continuity: Achieved the primary goal of migrating on-premise infrastructure without impacting business functions.
  • Future Readiness: Established a robust, scalable infrastructure that positions Lift and Shift Migration for future growth and innovation.
  • Optimized Performance: Enhanced application performance and resource utilization, driving overall business efficiency.
  • Long-term Cost Savings: Sustained infrastructure maintenance and operational costs well below initial projections.

The successful execution of this lift-and-shift migration project not only resolved immediate operational concerns but also positioned the client advantageously for future developments in their IT landscape.
