Organisation Cloud Migration For Core Business Application On OCI Cloud
- 1. Petronas Cloud Migration For Core Business Application Presenter : Rohan Singh
- 2. Project Overview & Objective ● Petronas currently operates an old traditional application on-premises. ● Business growth and increasing customer demand are driving the need for modern infrastructure. ● The application faces higher customer frequency, highlighting the need for scalability. ● A critical requirement is maintaining the security of sensitive data during migration. ● The main objective is to build a scalable, highly available, and fault-tolerant infrastructure. ● Data security is essential, with protection for both in-transit and at-rest data. ● The infrastructure must be secured against various cyber threats. ● The organization seeks a cost-efficient solution with disaster recovery capabilities. ● Cloud migration is identified as the optimal path to achieve these objectives. ● Benefits the organisation by saving cost of maintenance and achieve pay as you go basis not investing large amount on on premises infrastructure at the start. ● We taking Oracle database itself as our database engine on premises
- 3. Key Requirements for Successful Cloud Migration ● To achieve high availability, fault tolerance, security, disaster recovery, and cost-efficiency, the project requires careful planning. We will adopt the Agile methodology for the migration process, ensuring effective tracking through tickets and sprint dashboards for smooth progress monitoring. ● Another major requirement is choice of cloud platform third party tools which will help us to fulfill the requirements in cost efficient way and meeting all the compliance(security and data integrity). ● The initial focus is to set up the cloud development environment and grant access to developers, ensuring uninterrupted development and meeting tight deadlines. ● The architecture will transform applications into containers for optimal resource utilization, providing a lightweight, cost-efficient, and secure solution to handle thousands of concurrent customers. ● To meet deadlines, we will automate the entire infrastructure from the start, including deployment and testing, to ensure high efficiency and quality. Although it may take longer initially due to script setup, it will save time in the long run. ● Sensitive data migration requires strong encryption, using third-party or cloud-native tools. Scalability for the database will be ensured through caching services and read replicas. ● To meet the RPO of 5 minutes and RTO of 30 minutes, a scaled-down, always-available infrastructure in a separate region is needed, with database sync and blue-green deployments of applications for each release cycle.
- 4. Choosing the Optimal Cloud Platform to Meet Business Requirements Feature GCP AWS OCI Security - IAM - Data encryption at rest and in transit - VPC Service Controls - IAM and granular access policies - KMS for encryption - Advanced security tools (GuardDuty) - IAM with granular access control - Encryption via Oracle Vault - Security Zones & Cloud Guard Disaster Recovery - Multi-region failover - Cross-region replication for Cloud SQL & Spanner - Global database (Aurora Global) - Cross-region replication for S3, RDS - Cross-region DR with Oracle Autonomous DB - DRaaS available for custom architectures Cost efficiency - Sustained use discounts - Preemptible VMs - Fine-grained scaling - Reserved Instances - Savings Plans - Spot Instances for cost savings - Flexible compute pricing (OCPUs) - Lower cost for enterprise workloads - Autonomous Database reduces cost
- 5. Choosing the Optimal Cloud Platform to Meet Business Requirements Feature GCP AWS OCI High Availability - Global load balancing across multi-regions - GKE for Kubernetes with HA - Regional storage replication -Multi-region/Availability Zones (AZ) with Auto Scaling Groups - EKS for Kubernetes - Cross-region replication - Multiple Fault and Availability Domains (ADs) - OKE (Oracle Kubernetes Engine) - Resilient across regions Scalability - GKE auto-scaling (pods & nodes) - Cloud SQL auto-scaling for DB - Serverless (Cloud Run) - EKS auto-scaling (containers, compute) - Aurora Serverless - Lambda for serverless workloads - OKE with auto-scaling - OCI Compute auto-scaling - Autonomous Database auto- scaling After Comparison Choice Offers a strong container ecosystem through Google Kubernetes Engine (GKE) with auto-scaling and multi- region support which can be achieved in other clouds and is cost efficient than AWS cloud. But AI tools and business could make it costlier in future. AWS provides strong DR planning support.However most expensive solution compared to other clouds. But have wide variety of options to select which other clouds also offers. OCI cloud Platform Cost-efficient for enterprise workloads due to flexible pricing and integrated services like Autonomous Database. And meets all the compliance requirements hence its the best choice.

Comparison In Data Migration Approach Criteria Data Pump with FastConnect GoldenGate with FastConnect DMS with FastConnect Cost Efficient High (one-time cost for Data Pump and FastConnect usage) Moderate to High (GoldenGate licensing and FastConnect costs) Medium (FastConnect costs, DMS is free) Security Secure with encrypted data transfer over FastConnect Enterprise-grade security with encryption and FastConnect Secure, FastConnect ensures private link High Availability No real-time sync, batch mode with some downtime Real-time data replication, zero downtime Minimal downtime depending on migration type Disaster Recovery Limited to backup/restore approach, no real- time failover Supports real-time failover and DR with continuous replication Can support failover but not real-time sync
- 8. Comparison In Data Migration Approach Criteria Data Pump with FastConnect GoldenGate with FastConnect DMS with FastConnect Pros - Simple, cost-effective solution and well planned downtime - Zero downtime with continuous replication - Real-time data sync for critical systems - Suitable for long-term, steady migration requires fastconnect Some downtime Best For Applications that can tolerate periodic downtime Mission-critical applications requiring zero downtime Applications needing steady migration with minimal downtime Recommended For Cost-efficient migrations with acceptable downtime Real-time, high availability, continuous sync Cost-effective for extended migrations with fewer interruptions

Expenses can be tracked for each environment, helping teams regularly optimize costs and scale infrastructure efficiently. ● Secure Infrastructure:The infrastructure is highly secure, using policies, WAF (Web Application Firewall), SSL certificates, and services like Vault to ensure data is protected. This setup makes the system highly trusted and secure. ● Improved Release Process:Automation has streamlined the release process, reducing the time required for new deployments. Teams now have better visibility of infrastructure activities, enabling faster rollbacks and more efficient scaling. ● Scalability & Traffic Management:The infrastructure has autoscaling enabled, ensuring it can handle variable loads. Load balancers distribute traffic efficiently, and a caching solution reduces the load on the master database by managing frequent read operations. ● Disaster Protection:The solution is protected against disasters, ensuring that natural calamities or accidental events do not impact the application's uptime, keeping the service always available. ● Efficient Resource Management:Resources are tracked and managed efficiently using tools like Jira, Agile practices, daily stand-ups, and proper documentation in Confluence. This ensures that all project information is organized and easily accessible, aiding in knowledge transfer and onboarding or offboarding of employees.
