How to Win When Migrating to Azure
1 like487 views
This document provides an overview of how to successfully migrate Oracle workloads to Microsoft Azure. It begins with an introduction of the presenter and their experience. It then discusses why customers might want to migrate to the cloud and the different Azure database options available. The bulk of the document outlines the key steps in planning and executing an Oracle workload migration to Azure, including sizing, deployment, monitoring, backup strategies, and ensuring high availability. It emphasizes adapting architectures for the cloud rather than directly porting on-premises systems. The document concludes with recommendations around automation, education resources, and references for Oracle-Azure configurations.

- 4. Thank you- Thank you for the being here today! Thank you to the PASS DatabaseVirtual Chapter Please ask questions throughout the session and I’ll try to answer them, may hold them to the end, if it makes sense. My contact info will be provided at the end. The slides will be uploaded and available- there’s A LOT of links for deeper information on all the content I will be covering.
- 5. WhyMigrate to the Cloud Get rid of the datacenter Scalability Pay for what’s used Easier access to resources More agile infrastructure Going to the cloud will not grant you massive savings.
- 6. Azure Data Platform Although I specialize in Oracle on Azure IaaS, there’s more opportunities to migrate to Azure than I can keep up with! https://azure.microsoft.com/en-us/services/#databases
- 7. Azure Database 101 What is Azure Infrastructure as a Service, (IaaS)? What is Azure Platform as a Service, (PaaS)? What Azure SQL Database ServiceTiers are there? How do I find the main information about Azure Databases? UnderstandingAzure Single Databases and Elastic Pools. What is an Azure SQL Managed Instance? Main How-to Guides for Azure Databases. Where do I find the Azure Roadmap for the future of Databases?
- 8. Oracle on Azure Oracle to PostgreSQL- 10% Oracle Cloud Infrastructure, (OCI) and Azure Interconnect- 10% Oracle to Azure IaaS- 80% Yeah, I’m the last one, btw
- 9. Oracle Workloads to Azure Lift and Shift theWorkload, not the hardware Use the Oracle sizing tool withAutomaticWorkload Repository, (AWR) reports to ensure sizing is correct. Don’t combine upgrades with migrations and architect for the cloud. Separate sizing from optimizing

- 11. Oracle for AzureSizing Tool Learn more about it here. Uses AWR reports to size out workloads Calculates the vCPU, memory and IO/MBps that will be required to run the workload in Azure
- 13. Migration toAzure- High LevelSteps Begin Begin migration/build. Agree Adjust pricing, ensure customer is in agreement and begin deployment of Azure services Adjust If needed, make adjustments to architecture based off results. Perform Perform POC for expected scenario Choose Choose a database to use for a POC if desired Propose Review with customer to ensure this meets their needs Create Review and create a proposal. Collect Collect workload usage for 24hrs or 7 days, depending on the workload type, (consistent vs. varied) Document Begin with spreadsheet of databases to migrate or create a DR environment for.
- 14. MostCommon Bottlenecks Refactoring of database or application tier Attempting to upgrade while migrating Not getting stakeholder buy- in Packaging complex goals in with the migration
- 15. GlobalTip #1 Don’t architect cloud solutions like you architected for on-prem Cloud infrastructure is different than an on-prem data center. May result in extra redundancy and/or gaps. Educate on the infrastructure and security already in the cloud Take egress into consideration with how processing occurs between systems. Identify, Inventory, Document and Diagram all. Involve all stakeholders. Choose your battles and create battle plans on what will be addressed first. Use tools available from the cloud provider
- 16. Azure PlanningTools SQL DTUCalculator is a translator and calculator that sizes out theAzure environment you will require vs. the current on-premises environments you have. A DTU, (DatabaseThroughput Units) is a form of cloud measure of the average CPU, IO and Memory to come up with minimum service level and tier of Azure service needed for migration: Processor - % ProcessorTime Logical Disk - Disk Reads/sec Logical Disk - DiskWrites/sec Database - Log Bytes Flushed/sec Azure Instances Information will provide the information you need to understand the wide variety of configurations and service levels/tiers that are available.
- 17. Database Archival and BlobStorage Azure Stretch Database is a way to move read only databases to low cost storage and have them automatically move from warm, (queried) to cold, (unused) storage that’s very cost effective. Azure Archive Storage is a way to store years of data at a lower cost, similar to stretch, but less RDBMS focused, automatic movement from warm to cold storage. Azure Blob Storage is an excellent choice for unstructured data, backup files, etc. Again, possesses automation to move files from hot, to warm, to cold storage. This goes for IaaS, too. Azure Site Recovery snapshots and backups can take advantage of this.
- 18. GlobalTip #2 Use the RightTool for the Job Don’t try to duplicate everything you have on-prem in the cloud. Locate what you need to accomplish and then discover what is the most efficient and compatible tool to reach your goal.
- 19. Tools to Help With Migration Azure Cloud Assessment reviews your entire A-to-Z environment and discovers what needs to be migrated, helps select a migration strategy, assists in the migration and helps optimize, post migration. Building a High AvailabilityArchitecture in Azure for SQL DB, for Oracle use this and Oracle DataGuard. Azure Database Migration Assistant is available to ease the migration steps if performed one-off. Database Platform Migration Assistant- no matter the data source, there is a migration path to Azure. Azure Site Recovery allows for backups to Azure and then path to migrate environments to Azure. Azure Data Sync is a free service that allows for data to be sync’d from on-premises to Azure environments. Azure Migrate is actually aVM migration tool for Azure.
- 20. GlobalTip #3 Don’t boil the ocean Break the project into achievable, bite size pieces. Don’t allow others to distract with unimportant issues or insignificant challenges. Ensure everyone signs off on what is agreed to. Perform a POC if it makes sense, but choose a viable workload to test.
- 21. Tip #4 Consider Services to Scale Most common failure point are those that try to LITERALLY lift and shift what they have on-prem into the cloud instead of taking the workload, the features and move those to the cloud. Consider: Cloud backup solutions likeVeeam, Commvault, ANF, ASR, etc. Data movement and transformation products likeADF, AAS, etc. Cloud analytics that are simpler to refactor than a database or application platform. Automate as part of your migration usingAzure DevOps, Github, etc. Use thin and thick clones over archaic data refresh technology
- 22. Templates, Libraries, etc. Use a scripting/automation factory to perform the work in an automated fashion. ARMTemplates Image Libraries Data MigrationGithub Solutions Modern DataWarehouse
- 23. Heavy IO and throughput demands When sizing aVM to use with an IaaS solution, ensure that you identify the Max cached and temp storage throughput for both IOPS and MB/s A larger disk may not always be the wise solution, when smaller, striped disks may provide more throughput. When needs surpass the VM capabilities, consider capacity pools by Azure NetApp Files or other solutions.

- 26. Monitoring Azure Insights, part of Monitor Azure Data Studio Solarwinds Database Performance Analyzer, (DPA), (multi-platform) Oracle Enterprise Manager, (Cloud Control)
- 27. Evolve Think about how you’ve done work on- prem- Will it perform and satisfy the requirements in the cloud? Are there services that can perform the task simpler and for less? What archaic can you leave behind? Can new projects be implemented on newer technology/platforms
- 28. Backup Servers Databases Applications Copy ARMTemplates Consider newer ways to “backup” Identify the RPO/RTO and build out solution that meets the requirements.
- 29. Security Encrypt data at the right layer, both at rest and in motion. Use best practice when securing database server as you would on- prem, but additional security with cloud environments. Identify overhead of security products and build out suite of solutions that meet requirements and SLAs ConsiderAzure Security Center
- 30. HighAvailability Consider Co-location UseAvailability Regions and Availability Scale Sets Use Always-onAG and Oracle Dataguard for database tiers UseAzure Site Recovery, (ASR) forVM snapshots and schedule snapshots for PaaS with viable retention times.
