Migrating Oracle Analytics Cloud to Generation 2 Cloud

Introduction

Cloud computing is used everywhere in the current world. Oracle has introduced Generation 2 (Gen 2) Cloud in 2018 to provide businesses with better performance, security and pricing, with a main focus on Enterprise Systems. Gen2 provides built-in security to reduce threats, effective automation and better scalability and availability. It helps us to manage data across different data types and provides advanced visual analytics. It is the only infrastructure built to run on industry’s first self-driving database i.e., Oracle Autonomous Database.

Gen1 Vs Gen2

In Gen1 Cloud, user data and code are placed on the same computer as the cloud control code and shares resources like CPU and memory, which means the cloud providers can access customer data, leading to security threats. Whereas in Gen 2 Cloud, customer code and cloud control code are placed on separate computers with different architecture. So, here even Oracle cannot access its customer data as it won’t have user access to the cloud control code.

Gen 1 Cloud is primarily aimed for organizations which are in need of building new applications on cloud rather than the existing applications. Gen 2 enables enterprises to replace their existing on-premise data centers with a cloud deployment model.

Gen 1 focused on being serverless and elastic whereas Gen 2 is centered on being secure and autonomous.

Advantages of migrating Oracle Services to Gen 2

  • Increased security
  • Improved performance
  • High scalability and availability
  • Autonomous centered
  • Supports all emerging technologies

Migrating Oracle Analytics Cloud (BI) to Gen 2

It is actually easy to migrate content and settings from one Oracle Analytics Cloud (OAC) environment to another using snapshots. We can migrate everything or restrict to specific types of content during migration. For migrating Oracle Services to Gen 2, we need to take care of few pre-migration steps and considerations such as downtime, scope, business requirements and strategy and so on.

Prerequisites for migration

  • The source as well as target environment must use OAC 5.1.x or later. Snapshots taken from the earlier versions don’t capture the entire environment.
  • Target must be created on Oracle Cloud Infrastructure (OCI).
  • To migrate file-based data, check whether both source and target environments are up, running and configured with valid storage credentials.

Note: Storage access issues may prevent data file migration using snapshots. In this case, we use Data Migration utility to download data files and then upload them separately.

Steps involved in migration using snapshots

  • Create the target service
  • Migrate users and groups
  • Take and download snapshot of the source locally
  • Upload and restore the snapshot content to target
  • Migrate data files
  • Reconfigure virus scanner and mail server
  • Migrate other snapshots (individual snapshots can be uploaded on target to migrate specific content)

For File-based data, OAC offers Data Migration utility which helps us to move data files to new location. Data Migration utility also helps in moving map-related plug-ins and extension files that users may need to upload for their data visualizations.

Conclusion
Gen 2 Cloud supports all the emerging technologies like machine learning, artificial intelligence, blockchain, IoT and human interfaces giving us an opportunity to innovate and benefit our customers. Gen 2 makes the systems more secure (by avoiding data losses) and automated (by reducing labor costs). With OAC, customers can derive data insights and make their mark by getting real value and faster results. So, it would be ideal for us to have our OAC environment in Gen 2 Cloud provided by Oracle.
