Overview

Our client’s mission-critical system provides online ordering and delivery of products directly to their clients, on-demand, and 24-hours a day. The application supports over $1.8B in annual revenues and was beginning to fail due to the architecture and physical environment.

Client's Goals

Our client sells products directly to their clients through brick-and-mortar retail outlets as well as online. The online business for all of Asia was delivered by a single platform on a stand-alone SQL Server environment and demand was steadily increasing. The on-set of COVID and the capability demands that were created were yet to be known.

Project

The cloudEQ team embarked on building a new environment in the cloud while the original platform continued to run the business. The cloudEQ team created six unique environments, one for each country in Asia, on AWS creating a new multi-tiered application using .net and SQL servers. The cloudEQ team took a parallel build approach, and once the new environment was up and running, they performed a country-by-country cutover, taking two months to complete seamlessly. Fortunately, the migration to the cloud project had started in 2019, before the highly rapid growth requirements.

Solution

Six environments created, one for each country and each with its own application/DB instance
Multi-tiered application development approach
Leveraging Microsoft SQL Server and .net architecture
Hosted on AWS using SQL AlwaysOn high-availability group cluster design
Clustered and fault-tolerant databases within the same region
Cross-region failover provided

Challenges

Outdated single platform environment created instability
A mission-critical application lacking current HA and management capabilities
No ability for regionalized business process support

Results

This 6-month project delivered a secure and scalable solution proven out during the on-set of COVID which required a 30% increase in capacity to be delivered on demand. Having just finished the final migration of the single platform to 6 regional environments, our customers quickly provided the customer service experience their customers have come to expect. The new environment-by-country solution provided additional web and application servers on the fly to scale as necessary.
