Evidian SafeKit on AWS

Helps companies secure 24/7 operation of critical applications

This Quick Start deploys an Evidian SafeKit cluster automatically on the Amazon Web Services (AWS) Cloud. SafeKit is a software-only high-availability product with synchronous real-time replication, network load balancing, and automatic failover. 

SafeKit helps companies secure 24/7 operation of critical applications. It addresses business continuity, disaster recovery, and scalability for Windows and Linux applications with redundancy and with active or passive backup servers. It does not require specific hardware, specific network configuration, or specific external storage. It lends itself to the AWS Cloud because it is hardware agnostic.  

Customers can configure clusters for a given application using one or more application modules: mirror modules, farm modules, or a combination. Mirror modules use primary and secondary servers with real-time file replication and failover. Farm modules use network load balancing combined with failover for up to four servers.


This Quick Start was created by Evidian in collaboration with AWS. Evidian is a wholly owned subsidiary of Atos. Atos is an AWS Partner.

  •  What you'll build
  • The Quick Start sets up the following:

    • A highly available architecture that spans two Availability Zones for the mirror module and up to four for the farm module.
    • A virtual private cloud (VPC) configured with public subnets, according to AWS best practices, providing you with your own virtual network on AWS.
    • An AWS Identity and Access Management (IAM) role that accesses the SafeKit Quick Start's Amazon Simple Storage Service (Amazon S3) bucket.
    • In the public subnets:
      • An Elastic IP address that gives access to the SafeKit web console.
      • One Amazon Elastic Compute Cloud (EC2) instance for either Linux or Windows.
      • A security group that allows inbound Secure Shell (SSH) or Windows Remote Desktop Protocol (RDP) access to the EC2 instances through the public IP addresses. The security group also allows access to the virtual IP port to the Elastic IP addresses.
      • A Network Load Balancer that balances traffic between the instances and checks the health of the SafeKit URL.

    The first diagram shows the mirror module:

    • Two servers—one primary and one secondary—that run in separate Availability Zones. The critical application runs on the primary server.

    The second diagram shows the farm module:

    • One to four servers that run in separate Availability Zones. The critical application runs in all servers in the farm.
  •  How to deploy
  • To deploy Evidian SafeKit, follow the instructions in the deployment guide. The deployment process, which takes about 30 minutes, includes these steps:

    1. If you don't already have an AWS account, sign up at, and sign in to your account.
    2. Launch the Quick Start. You can choose from these options:
    3. Test the deployment.

    Amazon may share user-deployment information with the AWS Partner that collaborated with AWS on the Quick Start.  

  •  Cost and licenses
  • You are responsible for the cost of the AWS services used while running this Quick Start reference deployment. There is no additional cost for using the Quick Start.

    The AWS CloudFormation template for this Quick Start includes configuration parameters that you can customize. Some of these settings, such as instance type, will affect the cost of deployment. For cost estimates, see the pricing pages for each AWS service you will be using. Prices are subject to change.

    Tip: After you deploy the Quick Start, we recommend that you enable the AWS Cost and Usage Report to track costs associated with the Quick Start. This report delivers billing metrics to S3 bucket in your account. It provides cost estimates based on usage throughout each month, and finalizes the data at the end of the month. For more information about the report, see the AWS documentation.

    Evidian SafeKit provides a free trial license that’s good for three days of continuous uptime. For a full license, contact an Evidian sales representative or an Evidian partner.
