Challenges and Roadblocks :
- Achieve a flexible, state-of-the-art infrastructure to address challenges and match growth;
- Improve performance and availability.
- On-premises Scalability Challenge: Since DSP Mutual Fund is an Enterprise Company in consumer finance segment, have unpredictable workload, hence they want the architecture and resources to be scalable.
- Increased Agility and use of advanced technologies: Usage of high scale data analysis, Kubernetes and AI based services is very difficult to manage on-prem.
- Enterprise grade security with third party proven integrations.
- Near Disaster recovery with high availability.
- Rigorous application monitoring and load testing to be done before finalizing application stack for their various business units.
- Faster GO-to Market rate: For multiple application hosting on Amazon web services with a mixture of IAAS and
- Modernization of legacy monolithic applications.
- Moving away from licensed based databases and adopt cloud native databases like Amazon Aurora in the long run.
- Long term retention in archival and easy retrieval of data for audit & compliance management
- Using RDS for reduced RTO and RPO.
- Building a Hybrid cloud strategy with a Hub and Spoke model as per RBI guidelines.
Proposed Solution :
Dedicated and Cloud Servers, High Availability, Load Balancers.
Considering DSP Mutual Fund requirements, we proposed AWS based solution considering following requirements.
- High availability & Scalability
- Performance & reliability
- Cost Optimization
Key solution design features include following :
Hosting monolithic IIS MSSQL standard application on amazon web services using the below well architected standards.
- Creating a single source of truth – Separate landscape for production and non-production environment for isolation.
- Using Next generation firewall for protection against generation 5 attacks.
- Communication of App and DB traffic via NGFW.
- Identity and access management with least privilege mechanism and MFA for the user credentials.
- Configuring SQL log shipping for HA and Near DR.
- Configure Direct connect using different ISP for redundancy
- Configured high availability for required applications and placed then behind the internal application load balancer.
- VPC endpoints are required to access AWS services privately from AWS LAN network instead of letting them traverse internet. Example of such services are, EKS cluster, AWS S3.
- Configured VPC flow logs to monitor traffic coming in to the NIC of the server and outgoing traffic.
- Snapshot policy for all the servers apart from the Commvault backup that has been configured on a virtual machine.
- Application servers configured at multiple AZ with load balanced using AWS Application load balancer.
- CloudTrail logs for the user activity logging has been enabled for Customer account and the logs are moved to S3 bucket for audit purpose and long-term retention.
- Kubernetes Cluster deployment
- Servers are configured with auto start /stop mode for cost optimization.
- Production servers accessed restricted via bastion hosts for additional layer of security.
- Configured Lambda for achieving custom DNS query resolving from on-premises to Application load balancer.
- Configured AWS inspector for findings that are non-compliant to CIS benchmarks in the architecture components deployed.
- Using AWS Config for CMDB management
- Configured Guard Duty for analysis of DNS, VPC and CloudTrail logs
- Configure Snapshot Lifecycle Policy for the servers in AWS.
Architecture Deployed :
Why Amazon Web Services :
Amazon web services is a pioneer in the field of open source technological integrations.
- Migration using Cloud Endure is the most efficient way of moving on-premises workloads to cloud with minimum problems.
- Customer wanted near DR, hence having multiple availability zones was a perfect fit.
