Xolani Health — Securing and Optimizing AI-Driven Healthcare
How Silicon Overdrive helped Xolani Health, a Nigerian-based AI health company, assess three AWS workloads using the AWS Well-Architected Framework.
Welcome to Silicon Overdrive!
CMS Systems is a market leader in cloud-based software solutions for the automotive industry, providing all-in-one dealership customer management solutions.
The CMS Sales Solutions ensure all prospects are attracted, captured, and followed up effectively, increasing test drives and all other actions that have been proven to increase sales.
All their partners are backed up by a team of automotive and software experts, focused on simplicity, ensuring their dealership has the best tools to close more deals in less time. Along with solutions for managing and growing dealership customer loyalty.
CMS Systems was rapidly expanding and their on-premise system was not sufficient for their growth. They experienced the risk of possible downtime, server, hardware and network-related inconsistencies that prompted the decision to fast-track their move to the AWS cloud.
At the AWS Summit at the Cape Town Convention Summit in 2019, CMS System got introduced to Silicon Overdrive. Once in touch, they requested Silicon Overdrive to architect a scalable, highly available and secure solution on the AWS Cloud.
They also had a business requirement to be POPIA and GDPR compliant as their clients store sensitive personal information that needed to be secured.
To meet their compliance and resolve data sovereignty issues, Silicon Overdrive moved the CMS Systems infrastructures to both Ireland and the Cape Town region in order to comply with POPIA and GDPR compliance regulations and corporate governance requirements.
They also split out their workloads into separate accounts in order to segregate workloads between clients, this allowed for easier management of clients.
Auto Scaling was configured for self-healing which allows for the increased reliability desired by the customer. Should the availability zone or the instance go down the self-healing auto scaling group will automatically spin up a new instance in the second availability zone to ensure there is no interruption to the end user. By also making use of Amazon FSx this allows for uninterrupted service when a new service is spun up.
CMS Systems is also able to decide and change, at a moment’s notice the Amazon EC2 instance type and size. This means that as they onboard clients quickly, they are not held back by the providers’ inability to scale the machine’s capabilities as and when they need it.
Silicon Overdrive implemented the AWS Application Load Balancer which increased scalability, allowed for minimal downtime and automatically accommodated increases in traffic. It also allows for monitoring CMS Systems’ health of its registered targets and routes traffic only to the healthy targets as required.
To ensure secure sign-in into their environment and thus increasing their overall security CMS Systems now make use of a Fortigate VPN, this IPSec VPN tunnel ensures that there is no traffic over the public internet when accessing their environment.
Since the migration to the AWS Cloud, CMS Systems has experienced no downtime and attracted more users to their platform. Their application has been able to run on a single instance with the ability to evolve and add more features.
The new solution met the requirement to be scalable so that CMS Systems could scale according to the increase in customers that they were experiencing. The flexibility to increase the instance sizes on the fly was a functionality that they didn’t previously have but now enjoy.
Silicon Overdrive architected a best practice scalable, highly available and secure solution on the AWS Cloud. CMS Systems intends to apply for their ISO27001 and requires their workloads to be compliant and secure.
CMS Systems has not only benefitted from the new infrastructure on AWS but are also enjoying the services that they are currently using. As a result of this, they are actively looking into other AWS services that will benefit their current and future workload.
Francois Kemp, Head of Development and IT CMS Systems said, “We selected Silicon Overdrive as our preferred Partner to assist us on our cloud journey. Their experience and knowledge on security and AWS Architecture has made our migration seamless.”
