Case Study - Part 1: RDS SQL Server Disaster Recovery (Geo-Replication) on AWS

Versant Holdings migrates a complex multi-tenant SaaS system to AWS and achieves RDS/SQL Server cross-region DR/HA & DWH/RedShift based analytics with CloudBasic

Database Server Replication in the Cloud

Cloud architecture includes multiple redundancies and scalability options to support the large workloads of a 365/24/7 multi-hospital environment.

EXECUTIVE SUMMARY: Versant manages an RN Residency program throughout a nationwide network of hospitals. The organization’s rapid growth and the increasing demand for IT resources eventually outgrew the capabilities of the original IT Infrastructure. Versant selected CloudBasic to migrate its systems to AWS and to lead the design of a complex architecture with multiple redundancies, scalability options, and reporting tools. CloudBasic leveraged its flagship BCDR tools to deploy the resulting AWS infrastructure.

The Client

Versant Holdings

Versant manages an RN Residency program throughout a nationwide network of hospitals. The organization’s rapid growth and the increasing demand for IT resources eventually outgrew the capabilities of the original IT Infrastructure. Versant selected CloudBasic to migrate its systems to AWS and to lead the design of a complex architecture with multiple redundancies, scalability options, and reporting tools. CloudBasic leveraged its flagship BCDR tools to deploy the resulting AWS infrastructure.

The Case

Versant’s original IT architecture was setup in a co-location facility. While it was adequate for the early stages of development of the organization, the rapid growth of Versant’s client base eventually started to overwhelm the available IT resources. The level of system complexity was gradually increasing, while requests for IT resources were growing rapidly at a pace that exceeded the available service capacity.

“Not only natural disasters, network or power outages can be the reason for our systems to go down. Software or human errors can also cause our systems to malfunction for prolonged periods of time. With tens of thousands of concurrent users, throughout 100+ hospitals, our systems must remain operational 365x24x7.”
- Jane Olson, Asst. VP, Service Delivery, Versant Holdings, LLC

Stress on the systems came from  workloads that were getting ever larger and users that were accessing the systems on a variety of devices at all hours of the day and from different locations throughout the US. Although the co-location facility was a state-of-the-art datacenter, its legacy provisioning workflows were gradually becoming a bottleneck.

Versant Holdings operates in a 365/24/7 environment with high-profile clients where unscheduled downtime and system performance degradation of any kind are unacceptable. Eventually it became clear that the initial IT system design would not be able to meet the demands of an expanding list of high-profile customers. Versant’s leadership was becoming more frustrated with their inability to execute on their service goals. The IT systems were becoming inflexible, slow, and segmented, making the deployment of a new service a painfully long process. Any change to the service structure required the system to be taken down, temporarily rendering the organization unable to deliver on its service pledge to customers and to fulfill its mission.

The Solution

Versant Holdings decided to look for a cloud solution that would bring its systems to the performance standards that were required for a 24/7 no-downtime-allowed environment. The solution had to be scalable, easy to manage, and include a reliable disaster recovery plan.

To migrate its systems to AWS Versant selected CloudBasic, a company known for its robust replication technology and demonstrated deep understanding of cloud deployments. CloudBasic ended up designing a complex architecture that includes multiple redundancies, scalability options, and reporting tools. The deployed solution leverages the flagship CloudBasic BCDR tools tha implement a number features, including:

  • DB Server Replication – across AWS regions.
  • Data Locality – local data stays in local regions.
  • Data Aggregation and BI Reporting - Data from 100 hospitals goes to RedShift, where all data is aggregated into a data warehouse for reporting purposes.
  • Read Replicas – continuously synched read replicas to offload data read loads from the primary RDS SQL server and act as a load balancer.
  • DR within AWS – West Coast to East Coast Disaster Recovery setup.
  • Cross AWS Accounts Replication – Store all DR artifacts in completely separate AWS accounts, to recover from a potential account level security breach (a feature unique to CloudBasic’s BCDR tools).

The Results

Simplicity, Efficiency, Scalability! Currently Versant runs 100% of their AWS infrastructure, utilizing CloudBasic’s flagship RDS SQL AlwaysOn Geo-Replication product to continuously mirror data of 100+ hospitals from AWS Oregon based RDS SQL Servers to AWS Virginia region RDS SQL Servers, with a latency of less than 1 min. They also utilize CloudBasic’s AlwaysOn product to upload data to RedShift and manage their reporting. The integrated analytics and reporting capabilities provide deep insights into residents’ performance along a number of dimensions and against benchmark values aggregated at different levels. The new environment is best characterized as one of simplicity and efficiency, accommodating customers of different size and structures, with the ability to adapt to the unique service requirements of each client facility.

The Versant RN Residency has become the benchmark program in the country, has been referenced in numerous articles, and has won the MS HUG Innovation Award for Delivery Transformation. For more information about Versant Holdings, please visit

Great product, fantastic support team!

We’re a small, growing company so our AWS budget is tight and the CloudBasic replication product is the perfect solution for our needs. This product has allowed us to implement a reliable, near real-time replication solution without resorting to expensive SQL Server/RDS replication solutions. The CloudBasic product has proven to be fast, reliable, easy to set up, use and manage.

Before our AWS migration we managed our own physical SQL Server installation and used SQL Server log shipping to sync our online and reporting databases with typical latencies of 15-30 minute range. With the CloudBasic solution our latencies are now in the 2-5 second range…  Read full review >>

CloudBasic is an AWS Rockstar!

The CloudBasic RDS Always-On/Geo-Replicate for SQL Server solution is an absolute lifesaver when working with RDS SQL Server! SQL Server on RDS falls short in a lot of aspects when it comes to replication and disaster recovery, and this solution makes the process seamless. We’re able to migrate very large amounts of data and keep the in sync while we move applications around, as well as create usable read-replicas that RDS simply doesn’t provide. Anytime we’ve run into any snags in the process, CloudBasic support has been right there available to help get things going right away. I’m truly impressed with the product and the company behind it!

five-starsGreat product, simplifies architecture and hassle free

CLOUDBASIC RDS Always-On/Geo-Replicate for SQL Server HA/DR/Redshift/S3 provided us a way to replicate multiple on site MSSQL DBs to other datacenters as well as Amazon RDS\EC2 and also from the cloud into our datacenters. After spending weeks of investigating how we could manage this using SQL’s own replication or writing our own replication jobs we found Cloudbasic. We were up and running within a hour and our DBA team could test replication paths hassle free and have full control over the source and destination DBs. The ability to replicate into SQL Web version saves us $10,000’s every year whilst maintaining the ability to have read\write replicas. The Cloudbasic support has been fantastic, helping us with any questions we have and also releasing new features to meet specific needs, we couldn’t ask for more from a product support group. I would highly recommend you trial this product if you are looking at any form of hybrid MSSQL replication and want the most cost optimised solution that works straight out the box (AMI).

five-starsExcellent product and support!

CloudBasic RDS AlwaysOn/Geo-Replicate for SQL Server HA/DR is an excellent product backed by great support. Using the pre-configured AMI we were up and running in minutes. Used CloudBasic to migrate SQL Server databases into RDS, followed by setting up cross-region Multi-AR RDS SQL replications for Disaster Recovery and Multi-AZ High Availability. It works well with RDS Multi-AZ, creates SQL Server read-replicas which can be used for reporting, data-locality and offloading of primary RDS SQL Servers. With help form the responsive CloudBasic support team we were able to migrate our databases with no down time. Setting up DR and HA was straightforward.

I strongly recommend the product and the CloudBasic advisory support team…  Read full review >>
