Problem Statement

Context

Digitalization program: 60% of around 300 applications to be moved on the cloud (public and private). Should be able to deploy a full application, and provision its underlying infrastructure, in one click.

Targets

  • Reduce Time To Market
  • Reduce Project and application hosting costs
  • Adapt to business needs with more product releases and better quality
  • Heavy backlog due to support tickets is needed to be reduced

Challenges

Multivendor teams for development, testing and support
Ever-changing regulatory restrictions for transactional data

Scope

  • Migrate approximately 180 Apps to Azure and HPE
  • Containerisation and orchestration for over 50 applications
  • Develop Hybrid Cloud Solution
  • Technology Stack
  • .NET core, ORACLE, Azure DevOps, Ansible, Service fabric, AKS
  • High Availability, High Resilience, Disaster Recovery
  • Security (AD, Data, Network, Application, Containers)
  • Monitoring and Feedback

Solution Approach

  • Cloud Readiness Assessment
  • Refactoring micro services architecture, redesign for resiliency
  • Plan for AKS clusters in multiple regions, Route traffic across multiple clusters by using Azure Traffic Manager, geo-replication for container image registries. Plan for application state across multiple clusters.
  • Security ( AAD, data encryption at rest and in transit. Network security,
    Docker Content Trust Signature Verification)
  • Multi cloud network connectivity (Direct Connect ,VPC peering, VPN, Gateway end points, Express Route)
  • Storage (Azure SQL, Cosmos DB)
  • Portfolio and project migration to Azure Board
  • Branching merging governance policy redefined
  • Use GitLab for Dynamic Application Security Testing, SonarQube for Source code quality indexing
  • Create Build pipelines for required technologies
  • Automation testing scripts and data preparation for Selenium and LoadRunner
  • Ansible to automate deployment
  • Monitoring – Azure Monitor, Dynatrace
  • Use Azure Advisor for cost optimisation

Benefits

  • Faster delivery of features
  • Stable and consistent environments
  • Small Code Changes
  • Greater collaboration between development, testing and operations team
  • Greater customer experiences
  • Better security
  • Full portability
  • High resilience
  • Early identification of vulnerabilities in code
