Cloud-native Data Platform Transformation | Accenture

  1. 1. Migrating Accenture’s application databases running in virtual machines in IaaS on cloud and on-premises to a PaaS model in a multi- cloud environment For Accenture to “live in the cloud,” one focus is to start using Platform- as-a-Service offerings from various cloud vendors. This approach will help our IT organization to shift from managing machines to serving the business by enabling faster time to market. A database platform services migration program involves moving most of Accenture’s virtual machine (VM)-hosted servers to either Microsoft Azure SQL managed instance (PaaS) or to Amazon Aurora. The goal is to eliminate 95% of our virtual machines in the next three years and to realize efficiencies by shifting maintenance responsibility to service providers. Application developers will also be able to take advantage of cloud-native services. CLOUD-NATIVE DATA PLATFORM TRANSFORMATION Read blog post Copyright © 2020 Accenture. All rights reserved
  2. 2. Challenge What Accenture Did People and Culture Value Delivered Accenture migrated our IT infrastructure from on-premise to having 95% of our IT infrastructure operating in the public cloud today. We are now “living in the cloud” by executing various strategies. To live in the cloud at scale and at pace, one focus area is to start using Platform-as-a- Service (PaaS) offerings from various cloud vendors. This approach will help our IT organization to shift our energy from managing machines to serving the business by enabling faster time to market. Our database platform services migration program involves moving most of Accenture’s VM-hosted servers to Microsoft Azure SQL managed instance (PaaS) or Amazon Aurora. We are teaming with Microsoft to be an early adopter of Azure SQL managed instance and Azure SQL PaaS and collaborating to help make Azure SQL enterprise ready. For our application teams, we developed and industrialized a new migration service to migrate their databases. We also performed a PaaS migration program with AWS, moving VM-hosted SQL servers to AWS Aurora. Accenture is applying the New now by teaming with Microsoft to be an early adopter of Microsoft Azure SQL and Azure SQL PaaS and helping to make Azure SQL enterprise ready. Similarly, a global IT team performed a PaaS migration program with AWS, moving VM-hosted SQL servers to AWS Aurora. Our IT team brainstormed with AWS, executing a plan to understand the effort required to migrate a set of applications from either VM-hosted SQL Server or AWS RDS-hosted SQL Server to AWS Aurora. Our goal is to eliminate 95% of our virtual machines in the next three years, to realize efficiencies by shifting maintenance responsibility to service providers, and take advantage of cloud-native services. The migration of databases has started and will increase as services are solidified. Anticipated outcomes include: • Eliminate server management tasks of monitoring and OS/SQL upgrades • Enhanced security and compliance • Hosting cost savings expected in year 2 and onwards CLOUD-NATIVE DATA PLATFORM TRANSFORMATION Migrating Accenture’s application databases running in virtual machines in IaaS on cloud and on-premises to a PaaS model in a multi-cloud environment Copyright © 2020 Accenture.

  4. 4. Moving IT infrastructure to the cloud is essential to being successfully positioned to use today’s new technologies. Accenture identified this opportunity several years ago when we undertook a migration of our IT infrastructure from on-premise to today having 95% of our IT infrastructure operating in the public cloud. We are now “living in the cloud” by executing various strategies. Our global IT organization recognizes further opportunities and business value stand to be gained through continued transformation. To live in the cloud at scale and at pace, one focus area is to start using Platform-as-a-Service (PaaS) offerings from various cloud vendors. This approach will help our IT organization to shift our energy from managing machines to serving the business by enabling faster time to market. CHALLENGE Copyright © 2020 Accenture.

  5. 5. WHAT ACCENTURE DID Accenture takes a multi-provider approach in choice of cloud services providers. Accenture takes a multi-provider approach in choice of cloud services providers. This approach not only spreads risk concentration, but also gives us flexibility to use the best-fit cloud services. A database platform services migration program involves moving the majority of the company’s virtual machine (VM)-hosted servers to either Microsoft Azure SQL managed instance (PaaS) or to Amazon Aurora.

  6. 6. WHAT ACCENTURE DID Migration to Azure SQL managed instance We are teaming with Microsoft to be an early adopter of Microsoft Azure SQL managed instance and Azure SQL PaaS. Managed instance is a new deployment option of Azure SQL Database, providing nearly 100% compatibility with the latest SQL Server on-premises (Enterprise Edition) Database Engine. The managed instance deployment model allows existing SQL Server IaaS customers to lift and shift their applications to PaaS with minimal application and database changes. The managed instance deployment option preserves all PaaS that greatly reduces management overhead and total cost of ownership. Azure SQL Database is a fully managed PaaS database engine that is being used for those applications built with a SQL engine running a single database per instance. A central team within our global IT’s Operations team is collaborating with a Microsoft team to help make Azure SQL managed instance enterprise ready—including hardening security, creating assets, industrializing a mass-migration process, and bringing automation to run at scale in an environment like Accenture’s. Our IT team developed and industrialized a new migration service to enable Accenture’s internal application teams to migrate their application databases with as little effort as possible. The steps, methods, and assets we developed include automated scripts to fast-track the migration assessment effort and published data migration utilities. The result is a set of assets and self-help documents that enable application teams to migrate on their own at their own schedule. Also important to a successful migration effort is staffing sufficient in-house experts as well as vendor partners to support migrations with additional support. Copyright © 2020 Accenture.

  7. 7. WHAT ACCENTURE DID AWS Aurora proof of concept Accenture takes a multi-provider approach in choice of cloud services providers. This approach not only spreads risk concentration, but also gives us flexibility to use the best-fit cloud services. A database platform services migration program involves moving many of the company’s virtual machine (VM)-hosted servers to Amazon Aurora. Balancing workload across cloud service providers demands a viable PaaS service in AWS for Accenture. A global IT team performed a PaaS migration program with AWS, moving VM-hosted SQL servers to AWS Aurora. Our IT team brainstormed with AWS, executing a plan to understand the effort required to migrate a set of applications from either VM-hosted SQL Server or AWS RDS-hosted SQL Server to AWS Aurora. The Aurora platform is promoted as a database freedom offering. Aurora is an alternative to the costlier AWS RDS (SQL Server) with added advantage of being a non-licensed, open-source database engine, freeing Accenture from licensed SQL. The hosting costs are expected to decrease with serverless options. After successfully migrating these applications within four months’ time, our IT team not only avoided expensive BYOL licensing costs, but also resumed our greater PaaS migration program of migrating 300 AWS RDS and EC2 instances to Aurora. The experience generated a new artifact detailing the process for large-scale SQL Server to Aurora migrations. “To use true cloud-native services and transform Accenture to be living in the cloud, we are adapting database platform-as-a-service offerings. This enables our IT organization to move away from the business of managing infrastructure and get into delivering value-added business outcomes.

  9. 9. VALUE DELIVERED Key anticipated outcomes include: • As-a-service model eliminates server management tasks of monitoring and OS/SQL upgrades • Enhanced security and compliance as service provider experts manage security • Hosting cost savings expected in year 2 and onwards Collaborating with Microsoft and Amazon on migrating to state-of-the-art database platform services is a demonstration of Accenture’s strategy to apply the New now. In teaming with Microsoft, Accenture is helping to make Azure SQL managed instance enterprise ready. With AWS, Accenture completed a successful proof of concept and can continue migrating databases from IaaS to PaaS Aurora. For Accenture, the end goal is to eliminate 95% of our virtual machines in the next three years and to realize efficiencies by shifting maintenance responsibility to service providers. Application developers will also be able to take advantage of cloud-native services. The migration of databases has started and will progressively increase as services are solidified.
