Customer Success Stories
Every day, Oracle Cloud Infrastructure customers experience great success upon migrating their custom applications to Oracle Cloud. Here are some success stories.
CMiC is a construction software firm that has been providing their Enterprise and Field solution to their customers for nearly 40 years, and today 27% of Engineering News-Record top 100 contractors use CMiC software. Built on an Oracle stack, this single-database platform solution provides the ability for customers to manage entire construction projects from concept to completion. They have consolidated their on-premises and Amazon Web Services applications on to Oracle Cloud Infrastructure. They chose Oracle Cloud Infrastructure because of its performance, security, and because it offers the best support for Oracle databases.
Allianz Technology is the technology provider for the global financial services company Allianz Group, which has annual revenues of $130 billion. They have extensive business intelligence operations using the SAS application suite, MicroStrategy, custom applications, and Exadata for data persistence. They were looking to migrate these applications to the cloud to be able to build new functionality faster, increase the elasticity of their infrastructure, and to reduce their overall cost. It was critical to them that their cloud solution provide Exadata-as-a-Service. Another critical requirement was that they could build the infrastructure with Terraform. They chose Oracle Cloud Infrastructure and worked closely with Oracle services to execute the project. They are expecting to see significantly reduced cost of ownership as a result of the move.
CERN is a European research organization that operates the largest particle physics laboratory in the world. They migrated their WebLogic infrastructure for mission-critical Java applications to Docker and Kubernetes on Oracle Cloud Infrastructure. Doing so allowed them to reduce their maintenance work so they could focus more on development work. It used to take them a half day to deploy a WebLogic cluster, after the migration that was reduced to 2 minutes. Using Oracle Cloud Infrastructure also allowed them to also add new Disaster Recovery options. Alberto Di Meglio, Head of the CERN OpenLab, expects that most, if not all, of their applications will be moved to the cloud.
Benefits of Oracle Cloud Infrastructure
Oracle Cloud Infrastructure offers unique services, infrastructure capabilities, tools, and support that are optimized for migrating custom applications running on Oracle databases.
- Guaranteed performance and cost-savings: There are significant performance benefits when you run your custom applications on Oracle’s cloud. Our unique non-oversubscribed networks and single-tenant offerings like bare metal compute and Exadata ensure consistent performance that surpass the performance of our customers’ dedicated data centers. Unlike other clouds, we also offer service level agreements to back up our performance guarantees. In addition, many services run cheaper, and to preserve your existing investments, you can also bring existing database licenses to Oracle’s cloud.
- Security from the core to the edge: Oracle Cloud Infrastructure provides enterprise grade security at every level of the stack, to ensure user isolation, data encryption at every stage of the life cycle, fine-grained security controls, compliance, and visibility through comprehensive log data and monitoring solutions. When you move your applications to Oracle Cloud you can control your security as well as, or better than your on-premises infrastructure.

Depending on your priorities, you may choose from a few different approaches to migrating your on-premises applications to the cloud. Oracle Cloud Infrastructure provides reference architectures that support a broad spectrum of options.
There are many factors that can impact the optimum migration path from on-premises to cloud:
Is the application complete, requires few updates, and has a fixed workload?
“Lift and Shift” is an approach that makes as few changes to the infrastructure as possible. It reduces the chances of introducing differences in behavior, while still delivering the cloud benefits of improved performance from using the best hardware, storage and networking, as well as the financial benefits of moving from a capex to an opex model. Improve the database by moving to a managed version of Oracle database, improving reliability and reducing admin workload.
Is the application still an active project, with regular updates and version releases?
“Move and Improve” lets you upgrade the components of your application infrastructure to the latest versions, such as migrating WebLogic to version 12.2 and Oracle database to version 19c, and uses an Oracle validated architecture that can be deployed from Terraform scripts. This implements the best practices for running applications on Oracle Cloud Infrastructure. This approach makes it easy to spin up/down instances of the applications for dev and test work and improves the quality of production releases.
Do you want to implement a cloud native architecture, with support for elastic scaling, continuous deployment, and self-healing?
This enables the deployment of WebLogic based applications on Kubernetes clusters of Docker containers. Using OKE, Oracle Cloud Infrastructure’s managed Kubernetes service, it is easy to build highly resilient, scalable infrastructure, while levering your existing application code. This infrastructure is ideal to modern devops approaches to software development.
Across each of these approaches, Oracle offers choices to use database-as-a-service options for your applications, while preserving your investment in perpetual database licenses through its “Bring-Your-Own-License” (BYOL) program.
|Current status||Goal||Type||Target Validated Architecture|
|Any custom application running on any Oracle database.||Improve reliability, performance, and security. Lower TCO. Minimize migration risk.||"Lift and Shift"||Move the application stack to a BM or VM on Oracle Cloud Infrastructure. Migrate database to Oracle Database Cloud Service (BYOL).|
|JavaEE/WebLogic applications running on any Oracle database.||As “Lift and Shift,” plus: upgrade to latest WLS, automate dev/test/production deployments, implement HA and DR, consolidate databases.||“Move and Improve”||Deploy JavaEE/WLS to VMs/BMs by using Terraform scripts. Migrate databases to Oracle Autonomous Database, Oracle Database Cloud Service (VM or BM) or Oracle Database Exadata Cloud Service. Implement advanced HA and DR options.|
|JavaEE/WebLogic applications running on any Oracle database.||As “Move and Improve,” plus: increase flexibility, elasticity, and improve developer productivity with extensive automation options.||“Modernization”||Deploy JavaEE/WLS to Docker/Kubernetes clusters, by using Terraform scripts.
