## Additional information
The following is a list of best practices related to migrating Oracle BI 12c to the AWS Cloud.
**Repository databases**
It’s a best practice to host Oracle BI 12c database schemas on an Amazon RDS for Oracle instance. This instance type provides cost-efficient and resizable capacity while automating administration tasks, such as hardware provisioning, database setup, patching, and backups.
For more information, see [Using the Oracle Repository Creation Utility on RDS for Oracle](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Oracle.Resources.RCU.html) in the *Amazon RDS User Guide*.
**Web and application tiers**
[Memory optimized Amazon EC2 instances](https://aws.amazon.com/ec2/instance-types/) are often well suited for Oracle BI 12c servers. Whatever instance type you choose, make sure that the instances that you provision meet your system’s memory usage requirements. Also, make sure that you [configure a sufficient WebLogic Java Virtual Machine (JVM) heap size](https://docs.oracle.com/cd/E49933_01/server.770/es_install/src/tins_postinstall_jvm_heap.html#:~:text=The%20default%20JVM%20heap%20size%20for%20WebLogic%20is%203GB.,file%20for%20Linux%20or%20setDomainEnv.) based on your Amazon EC2 instance’s available memory.
**Local storage**
I/O plays an important part in the overall performance of your Oracle BI 12c application. Amazon Elastic Block Store (Amazon EBS) offers different storage classes that are optimized for different workload patterns. Make sure that you choose an Amazon EBS volume type that fits your use case.
For more information about EBS volume types, see [Amazon EBS features](https://aws.amazon.com/ebs/features/) in the Amazon EBS documentation.
**Shared storage**
A clustered Oracle BI 12c domain requires shared storage for the following resources:
+ Configuration files
+ Oracle BI 12c singleton data directory (SDD)
+ Oracle global cache
+ Oracle BI Scheduler scripts
+ Oracle WebLogic Server binaries
You can meet this shared storage requirement by using [Amazon EFS](https://aws.amazon.com/efs/), which provides a scalable, fully managed elastic Network File System (NFS) file system.
*Fine tuning shared storage performance*
Amazon EFS has two [throughput modes](https://docs.aws.amazon.com/efs/latest/ug/performance.html#throughput-modes): **Provisioned** and **Bursting**. The service also has two [performance modes](https://docs.aws.amazon.com/efs/latest/ug/performance.html#performancemodes): **General Purpose** and **Max I/O**.
To fine tune performance, start by testing your workloads in the **General Purpose** performance mode and **Provisioned** throughput mode. Doing these tests will help you determine if those baseline modes are sufficient to meet your desired service levels.
For more information, see [Amazon EFS performance](https://docs.aws.amazon.com/efs/latest/ug/performance.html) in the *Amazon EFS User Guide*.
**Availability and disaster recovery**
It’s a best practice to deploy Oracle BI 12c components across multiple Availability Zones to protect those resources in the event of an Availability Zone failure. The following is a list of availability and disaster recovery best practices for specific Oracle BI 12c resources hosted in the AWS Cloud:
+ **Oracle BI 12c repository databases**: Deploy a multi-AZ Amazon RDS database instance to your Oracle BI 12crepository database. In a multi-AZ deployment, Amazon RDS automatically provisions and maintains a synchronous standby replica in a different AZ. Running an Oracle BI 12c repository database instance across Availability Zones can enhance availability during planned system maintenance and help protect your databases against instance and Availability Zone failures.
+ **Oracle BI 12c Managed Servers**: To achieve fault tolerance, it’s a best practice to deploy Oracle BI 12c system components on Managed Servers in an Amazon EC2 Auto Scaling Group configured to span multiple Availability Zones. Auto Scaling replaces faulty instances based on [Amazon EC2 health checks](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-health-checks.html). In the event of an Availability Zone failure, Oracle HTTP Servers continue to direct traffic to Managed Servers in the functioning Availability Zone. Then, Auto Scaling launches instances to keep up with your host count requirements. Activating HTTP session state replication is recommended to help make sure that there’s a smooth failover of the existing sessions to the functioning Managed Servers.
+ **Oracle BI 12c Administration Servers:** To make sure that your Administration Server has high availability, host it in an Amazon EC2 Auto Scaling group configured to span multiple Availability Zones. Then, set the minimum and maximum size of the group set to **1**. If an Availability Zone failure occurs, Amazon EC2 Auto Scaling starts up a replacement Administration Server in an alternate Availability Zone. To recover any failed underlying hosts within the same Availability Zone, you can activate [Amazon EC2 Auto Recovery](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-recover.html).
+ **Oracle Web Tier servers:** It’s a best practice to associate your Oracle HTTP Server with your Oracle WebLogic Server domain. For high availability, deploy your Oracle HTTP Server in an Amazon EC2 Auto Scaling group configured to aspen multiple Availability Zoness. Then, place the server behind an ELB elastic load balancer. To provide additional protection against host failure, you can activate Amazon EC2 Auto Recovery.
**Scalability**
The elasticity of the AWS Cloud helps you scale applications either horizontally or vertically in response to workload requirements.
*Vertical scaling*
To vertically scale your application, you can change the size and type of the Amazon EC2 instances that are running your Oracle BI 12c components. You don’t need to over-provision instances at the start of your deployment and incur unnecessary cost.
*Horizontal scaling*
Amazon EC2 Auto Scaling helps you horizontally scale your application by automatically adding or removing Managed Servers based on workload requirements.
**Note**
Horizontal scaling with Amazon EC2 Auto Scaling requires scripting skills and thorough testing to implement.
**Backup and recovery**
The following is a list of backup and recovery best practices for specific Oracle BI 12c resources hosted in the AWS Cloud:
+ **Oracle Business Intelligence metadata repositories:** Amazon RDS automatically creates and saves backups of your database instances. These backups are retained for a period of time that you specify. Make sure that you configure your Amazon RDS backup duration and retention settings based on your data protection requirements. For more information, see [Amazon RDS backup and restore](https://aws.amazon.com/rds/features/backup/).
+ **Managed Servers, Administration Servers, and Web Tier servers:** Make sure that you configure [Amazon EBS snapshots](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSSnapshots.html) based on your data protection and retention requirements.
+ **Shared storage:** You can manage backup and recovery for files stored in Amazon EFS by using [AWS Backup](https://docs.aws.amazon.com/efs/latest/ug/awsbackup.html). The AWS Backup service can also be deployed to centrally manage backup and recovery of other services, including Amazon EC2, Amazon EBS, and Amazon RDS. For more information, see [What is AWS Backup?](https://docs.aws.amazon.com/aws-backup/latest/devguide/whatisbackup.html) In the *AWS Backup Developer Guide*.
**Security and compliance**
The following is a list of security best practices and AWS services that can help you protect your Oracle BI 12c applications in the AWS Cloud:
+ **Encryption at rest:** Amazon RDS, Amazon EFS, and Amazon EBS all support industry standard encryption algorithms. You can use [AWS Key Management Service (AWS KMS)](https://docs.aws.amazon.com/kms/latest/developerguide/overview.html) to create and manage cryptographic keys and control their use across AWS services and in your applications. You can also configure [Oracle Transparent Data Encryption (TDE)](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.Oracle.Options.AdvSecurity.html) on the Amazon RDS for Oracle database instance that’s hosting your Oracle BI 12c repository database.
+ **Encryption in transit:** It’s a best practice to activate either SSL or TLS protocols to protect data in transit between the various layers of your Oracle BI 12c installation. You can use [AWS Certificate Manager (ACM)](https://aws.amazon.com/certificate-manager/) to provision, manage, and deploy public and private SSL and TLS certificates for your Oracle BI 12c resources.
+ **Network security**: Make sure that you deploy your Oracle BI 12c resources in an Amazon VPC that has the appropriate access controls configured for your use case. Configure your security groups to filter inbound and outbound traffic from the Amazon EC2 instances that are running your installation. Also, make sure that you configure [Network Access Control Lists (NACLs)](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-network-acls.html) that allow or deny traffic based on defined rules.
+ **Monitoring and logging**: You can use [AWS CloudTrail](https://aws.amazon.com/cloudtrail/) to track API calls to your AWS infrastructure, including your Oracle BI 12c resources. This functionality is useful when tracking changes to infrastructure or when conducting a security analysis. You can also use [Amazon CloudWatch](https://aws.amazon.com/cloudwatch/) to view operational data that can provide you with actionable insight into the performance and health of your Oracle BI 12c application. You can configure alarms and take automated actions based on those alarms, too. Amazon RDS provides additional monitoring tools, including [Enhanced Monitoring](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Monitoring.OS.html) and [Performance Insights](https://aws.amazon.com/rds/performance-insights/).
