This Partner Solution was created by SIOS Technology Corp. in collaboration with Amazon Web Services (AWS). Partner Solutions are automated reference deployments that help people deploy popular technologies on AWS according to AWS best practices. If you’re unfamiliar with AWS Partner Solutions, refer to the AWS Partner Solution General Information Guide.

Overview

This guide covers the information you need to deploy the SIOS LifeKeeper for Linux Partner Solution in the AWS Cloud.

SIOS LifeKeeper for Linux is a Linux clustering application providing a tightly integrated combination of high availability failover clustering, continuous application monitoring, data replication, and configurable recovery policies. SIOS LifeKeeper for Linux includes SIOS LifeKeeper, SIOS DataKeeper, and multiple Application Recovery Kits (ARKs) to protect your business-critical applications and data from downtime and disasters.

SIOS LifeKeeper for Linux on AWS provides all the elements you need to create a high availability Linux cluster in a virtual private cloud (VPC) within a single AWS Region across two Availability Zones. It also supports out-of-the-box protection for SAP systems, Oracle databases, and other business-critical applications.

Costs and licenses

There is no cost to use this Partner Solution, but you will be billed for any AWS services or resources that this Partner Solution deploy. For more information, refer to the AWS Partner Solution General Information Guide.

Architecture

Deploying this Partner Solution with default parameters builds the following SIOS LifeKeeper for Linux environment in the AWS Cloud.

Architecture
Figure 1. Partner Solution architecture for SIOS LifeKeeper for Linux on AWS

As shown in Figure 1, this Partner Solution sets up the following:

  • A highly available architecture that spans two Availability Zones.*

  • A VPC configured with public and private subnets, according to AWS best practices, to provide you with your own virtual network on AWS.*

  • In the public subnets:

    • Managed network address translation (NAT) gateways to allow outbound internet access for resources in the private subnets.*

    • Linux bastion hosts in an Amazon Elastic Compute Cloud (Amazon EC2) Auto Scaling group to allow inbound SSH (Secure Shell) access to Amazon EC2 instances in public and private subnets.*

  • In the private subnets, two cluster nodes featuring SIOS LifeKeeper for Linux.

  • Amazon CloudWatch log groups to monitor, store, and access log files from EC2 instances.

  • AWS Systems Manager runbook to automate the deployment.

* The template that deploys this Partner Solution into an existing VPC skips the components marked by asterisks and prompts you for your existing VPC configuration.

Component Details

VPC

Single AWS Region with two Availability Zones.

Instance type

Minimum recommended instance type: t2.medium.

Operating system

See the SIOS LifeKeeper for Linux Support Matrix.

Elastic IP

One Elastic IP address connected to each bastion host instance.

Instances

Two instances: two SIOS LifeKeeper for Linux cluster nodes.

Volumes

Two volumes (gp2 or io3) per cluster node: one home volume (/) and one additional volume for replicated data storage.

Deployment options

This Partner Solution provides the following deployment options:

This Partner Solution provides separate templates for these options. It also lets you configure Classless Inter-Domain Routing (CIDR) blocks, instance types, and SIOS LifeKeeper for Linux settings.

Predeployment steps

Subscribe to the SIOS LifeKeeper for Linux AMI

This Quick Start uses Amazon Machine Images (AMIs) from the AWS Marketplace. Before you launch the Quick Start, you must subscribe to one of the SIOS LifeKeeper for Linux AMIs.

Two licensing options are available: Bring Your Own License (BYOL), and pay as you go (PAYG).

BYOL option

  1. If you’re planning to use the BYOL licensing option, obtain a permanent license by contacting SIOS directly. You can also sign up for a free, 14-day, trial license.

  2. Log in to the AWS Marketplace at https://aws.amazon.com/marketplace.

  3. Open the page for either SIOS LifeKeeper for Linux on RHEL – BYOL or SIOS LifeKeeper for Linux on RHEL – PAYG. Choose Continue.

  4. Choose Manual Launch, and then choose Accept Software Terms. For more information about AWS Marketplace, see Getting started.

PAYG option

To use a PAYG basic license, choose PAYG for the SIOS AMI license type parameter during deployment.

Deployment steps

  1. Sign in to your AWS account, and launch this Partner Solution, as described under Deployment options. The AWS CloudFormation console opens with a prepopulated template.

  2. Choose the correct AWS Region, and then choose Next.

  3. On the Create stack page, keep the default setting for the template URL, and then choose Next.

  4. On the Specify stack details page, change the stack name if needed. Review the parameters for the template. Provide values for the parameters that require input. For all other parameters, review the default settings and customize them as necessary. When you finish reviewing and customizing the parameters, choose Next.

    Unless you’re customizing the Partner Solution templates or are instructed otherwise in this guide’s Predeployment section, don’t change the default settings for the following parameters: QSS3BucketName, QSS3BucketRegion, and QSS3KeyPrefix. Changing the values of these parameters will modify code references that point to the Amazon Simple Storage Service (Amazon S3) bucket name and key prefix. For more information, refer to the AWS Partner Solutions Contributor’s Guide.
  5. On the Configure stack options page, you can specify tags (key-value pairs) for resources in your stack and set advanced options. When you finish, choose Next.

  6. On the Review page, review and confirm the template settings. Under Capabilities, select all of the check boxes to acknowledge that the template creates AWS Identity and Access Management (IAM) resources that might require the ability to automatically expand macros.

  7. Choose Create stack. The stack takes about 30 minutes to deploy.

  8. Monitor the stack’s status, and when the status is CREATE_COMPLETE, the SIOS LifeKeeper for Linux deployment is ready.

  9. To view the created resources, choose the Outputs tab.

Troubleshooting

For troubleshooting common Partner Solution issues, refer to the AWS Partner Solution General Information Guide and Troubleshooting CloudFormation.

Customer responsibility

After you deploy a Partner Solution, confirm that your resources and services are updated and configured—including any required patches—to meet your security and other needs. For more information, refer to the Shared Responsibility Model.
