About the Organization
Cirrus Insight is a SaaS-based CRM automation platform that connects email, calendar, and sales workflows with tools like Salesforce and Microsoft 365. The platform supports thousands of users and delivers integrated solutions to improve sales productivity and customer engagement.
The organization operates a cloud-based application environment on Microsoft Azure, with frontend and backend services supporting its CRM solution. Azure serves as the primary platform for application hosting, data management, and service delivery across its user base.
Challenge
With the application hosted on Azure Virtual Machines, managing infrastructure and application services became increasingly complex as usage scaled. Key challenges included:
-
- Limited scalability Manual VM-based scaling could not respond quickly to spikes from 10,000–15,000 concurrent users.
- High operational overhead Ongoing OS patching, VM lifecycle management, and manual deployments required significant engineering effort.
- Deployment risks Lack of structured release mechanisms such as blue-green deployments increased the risk of downtime during updates.
- Cost inefficiencies VMs operated at fixed capacity, leading to higher costs during periods of low utilization.
- Governance and visibility gaps Inconsistent tagging, limited policy enforcement, and lack of centralized diagnostics affected monitoring and compliance.
Solution
IFI Techsolutions designed and implemented a cloud-native architecture on Microsoft Azure, moving from IaaS to a PaaS-based model. The solution focused on improving scalability, reducing infrastructure management, and enabling controlled deployments. IFI Techsolutions implemented the following key elements as part of the solution:
- Application and database modernization
The application was migrated from Azure Virtual Machines to Azure App Service and Azure Container Apps, while SQL Server on a virtual machine was replaced with Azure SQL Database using an elastic pool configuration. - Scalable architecture design
App Service and Container Apps were configured with auto-scaling to dynamically adjust resources based on user demand. - Clear and timely reporting
Dashboards gave teams current views of transactions, budgets, inventory levels, and resource usage. - Secure networking and access control
Secure networking was implemented using Azure Front Door with WAF, private endpoints, and controlled outbound access. Microsoft Entra ID and managed identities were configured to enable secure access across services. - Automated deployment and infrastructure management
Azure DevOps pipelines were set up to support structured CI/CD workflows, supported by Terraform and Bicep for infrastructure as code. - Monitoring, observability, and security
Azure Monitor, Log Analytics, and Application Insights were configured for visibility, and Microsoft Defender for Cloud was enabled to strengthen security and compliance.
- Application and database modernization
