Engagement Approach
Application Development Model
Phase 1: Conceptualise
- Collaborate with Client to understand existing business processes
- Identify areas of improvement via digitisation based on data collected
- List down the Requirement Considerations
- Proceed to Phase 2 upon receiving Estimation Approval by Client
Phase 2: Prototype Engineering
- Solution concept strategizing based on Requirement Analysis performed in Phase 1
- Engineer a root-level construction and technical consultation
- Build and present a Prototype
- Selection of the suitable development platforms and their structure
- Preparation and finalisation of the resource plan
Phase 3: Design, Development & Implementation
- Application Design considering best industry-standard practices
- Personalisation of Design and its Evaluation
- Preparation of Release Plan
- Full-stack Development & Implementation
- Process optimisation
- Reviewing of application code and testing/bug fixing
Phase 4: Validation and Quality Assurance
- Performing multi-level enterprise-grade Application Testing procedures for desired output, zero errors and robust security features
- End-User Testing and Validation in real-time
- Brainstorm with Client for Suggestions and Feedback
- Achieve readiness for Application Release
Phase 5: Deployment and Production Launch
- Deploy Developed application to the business (production) environment
- Continuous monitoring of Security, Integrity, Accessibility of business data
Cloud Provisioning & Migration Model
Phase 1: Assessment
- Kick-off meeting with Client to understand project scope
- Analysis of Client’s existing IT Infrastructure
Phase 2: Cloud Readiness
- Perform the cloud readiness assessment considering business requirements, application life cycle, application architecture, data, infrastructure, security, integration, and operation
Phase 3: Requirement Gathering
- Requirement gathering for target architecture (Data availability, performance, security, privacy, and regulatory compliance aspects inclusive)
Phase 4: Migration Mode Selection
Based on existing landscape assessment and requirement gathering, choose the apt mode of cloud migration from below 5 R’s
- Re-host
- Re-platform
- Refactor
- Retain
- Retire
Phase 5: Design and Document Target Architecture
Based on performance, availability, security, regulatory compliance considerations
- Decide Integration patterns
- Specify server/instance for each workload component
- Specify network topology
- Specify storage architecture
- Design MAA(Maximum Availability Architecture) Policy and implementation
- Design application architecture
Define operation consideration including – monitoring, administration and maintenance Preparation of proper test and validation strategy to ensure the wellbeing of infrastructure and all associated components
Phase 6: Deploy infrastructure on public cloud
- Perform security, network and storage configurations
- Creation of cloud Instance and server hardening
- Install and configure database and application software
- Implementation of MAA as per design
- Enable operational considering including - monitoring, administration and maintenance
Phase 7: Test and validate Cloud Infrastructure
- Testing of all components including data validation, accessibility, performance, security etc. as per defined test strategy
Phase 8: Transition/Go-Live
- Migration execution to business (production) environment
- Hardening of the production environment
- Enable validation dry runs
- Status checks of operational enablement (monitoring, administration and maintenance)
- Shut down the existing on-premises environment in case of migration
Maintenance & Governance Approach
For stable infrastructure and excellent application performance, NITS takes care of the following Maintenance measures:
Performance Benchmarking
- Identify various Key Performance Indicators and Benchmarks for infrastructure, application, database along with security, accessibility, availability, the usability of data and application
Continuous Monitoring
- Comprehensive monitoring to measure defined KPIs and overall infrastructure health
Proactive Maintenance to prevent failure
- Maintenance of Server, Application, Database, and Infrastructure.
- Support activities catering across the following areas but not limited to:
- OS/application/software upgrade
- Installation of updates and security patches
- Checking of resource and disk utilization
- Password Management
- Security Management
- Billing Management
- Backup availability and tracking as per the schedule
Continuous Availability
- Ad Hoc failure resolution/repair by performing Root Cause Analysis for failure and check the possibility for permanent fixes
- Implementation of identified fixes
- Disaster Recovery of Infrastructure/server/application/database
- Perform Periodic mock exercises
- Disaster Recovery plan design and validation
Transparency in Infrastructure Health
- Clients to get periodic report/update regarding their infrastructure health
- Immediate notifications in case of any failures or upon detection of issues as a result of monitoring
- Required resolution measures to be taken to overcome failure/issues post discussion and agreement with the client team
- Informing the client in case of resource scale up or scale down needs
- Implementing the discussed changes post client agreement
