As a data scientist, did you ever come to the point where you felt the need for an evolved analytics platform bringing together the disparate skills of open source and commercial software? A system that can enable advanced analytic capabilities. This is now possible and easy to implement. With many deployment possibilities, SAS Viya allows you to choose the data storage location where compute happens, and the deployment methods for models.
Let’s say you want to expand your model development process with SAS Viya analytical capabilities and you don’t want to wait for getting such environment up and running. Unfortunately, you have no infrastructure, nor the experience to install SAS Viya. Moving the traditional way, you could go for:
- Protracted hardware procurement and provisioning
Deployment planning and coordination with IT
Effort and time required for software installation/configuration
This solution may be the right path for many organizations, but I think we all recognize this: the traditional approach could take days, weeks and yes sometimes months.
What if you could get up and running with a full SAS Viya platform in two hours? If you have some affinity for cloud-based solutions, SAS offers you the AWS SAS Viya Cloud Rapid Deployment tool. SAS released this AWS Quick Start as a rapid deployment architecture for SAS Viya on AWS. Deployable products include SAS Visual Data Mining and Machine Learning, SAS Visual Statistics and SAS Visual Analytics.
The goal of this article is to brief you how I launched such an AWS SAS Viya Quickstart. I strongly advise you to watch this related video by my colleague Erwan Granger. Much of what is covered here appears in Erwan's video. The recording predates the SAS Viya 3.4 release, but main concepts are still the same.
What you will need
The following is a list of items you need to complete this task.
- AWS Account with appropriate creation privileges
A valid SAS Viya License; this means you will need a SAS Software Order Confirmation e-mail
Optional: you deploy with your own DNS Name and SSL Certificate. In that case you need to register a domain managed by Amazon Route 53. For instructions on registering the domain, see the Route 53 documentation. And you can request and register a certificate with AWS Certificate Manager.
Furthermore, it’s good to know this Quick Start provides two deployment options. You can deploy SAS Viya into a new Virtual Private Cloud (VPC) or into an existing VPC. The first option builds a new AWS environment consisting of the VPC, private and public subnets, NAT gateways, security groups, Ansible controllers, and other infrastructure components, and then deploys SAS Viya into this new VPC. The second option provisions SAS Viya in your existing AWS infrastructure. I decided to go for the first option.
What you will build
Here's an architectural overview of what we will build:
SAS Viya architecture on the AWS Cloud
You can find exactly the same architecture on the SAS Viya AWS Quick Start landing page.
Configure the build
We’ll be following the build process outlined in the Quick Start guide. On the landing page, next to the "What you’ll build tab" you can click on "How to deploy". From there launch the "Deploy into a new VPC" wizard.
Deploy into a new VPC wizard
Make sure you sign in with your AWS account and you have chosen the region where you want to deploy. On that first screen you can leave the Amazon S3 template URL default. That template is the basics for the AWS CloudFormation we are launching. CloudFormation is a tool from AWS that allows you to spin up resources in the right order. The template is the blueprint document for your CloudFormation. By keeping the default template, we will build exactly the architecture displayed above.
Pre-req prep template
Now click "Next" and move to the page where we can specify more details and the required parameters of the CloudFormation parameters.
The first parameter is the SAS Viya Software Order file, which is the Amazon S3 location of the Software Order e-mail attachment.
SAS Viya install package location
In the Administration section, you provide parameters to configure your AWS architecture. That way, you control access, instance type, and if you will use a SAS Viya Mirror repository.
CloudFormation administration parameters
Administration parameter definitions:
- The name of an Amazon EC2 key pair, so you can access the Ansible controller
The Amazon Availability zone for the public and private subnet
Allowable IP range for HTTP traffic; must be a valid IP CIDR range
Allowable IP Range for SSH traffic to the Ansible controller; must be a valid IP CIDR range
SAS Administrator password
Password for Default (sasuser) user
Amazon EC2 Instance type for CAS Compute VM
Amazon EC2 Instance type for SAS Viya Services VM
(Optional) Location of SAS Viya Deployment Repository data
(Optional) Operator Email
If you want to work with custom DNS names and SSL, you will need to provide the next three parameters as well.
DNS and SSL configuration (optional)
DNS and SSL parameters:
You may accept the defaults on the remaining parameters.
After clicking "Next" another set of optional parameters are available. I mostly go with accepting the default parameters provided. The lone exception is the Rollback on failure.
Optional administration parameters
Based on what I’ve learned from Erwan's video, the safer choice is "No" on the Rollback option. This way, if the deployment process encounters issues, the log will identify in which step the error occurred. Of course this means you are responsible to manually delete AWS created resources that are not longer necessary. The easiest way to do this is by deleting the CloudFormation Stacks afterward.
Kick off the build
To conclude the deployment wizard, click "Next" once more and acknowledge the necessary AWS resources to create. By clicking "Create stack" the deployment process starts.
Start the build process
You can monitor the deployment log using AWS CloudWatch. In his video, Erwan demonstrates this at around minute 23.
After a successful formation you will find two AWS CloudFormation Stacks created. The Outputs gives you the direct links to SAStudioV and SASDrive.
SAS Studio and SAS Drive stacks
That’s it. You are deployed and ready to begin using your SAS Viya environment!
