Our client, a prominent investment management firm, faced significant challenges due to their rigid infrastructure and architecture. As an investment company, maintaining constant availability — 24/7, 365 days a year — is not just essential but a cornerstone of their commitment to customer trust and industry excellence. These limitations hindered their ability to effectively manage disaster recovery and perform smooth rollbacks in the event of critical bugs. The inflexible system led to frequent maintenance windows, which disrupted service availability and negatively impacted user experience.
Users experienced interruptions during deployment periods, and critical bugs could result in prolonged service outages. The lack of a robust disaster recovery plan made the system vulnerable to regional outages, further compromising service reliability and user satisfaction. The firm needed a solution to enhance system resilience, ensure uninterrupted service, and provide a seamless user experience even during maintenance or emergencies.
Given that the goal was to ensure smooth and seamless updates to software while drastically minimizing disruption and risks, we would need a strong release management strategy. The application userbase was active throughout the day, creating a unique challenge in identifying the best maintenance window for the latest updates. Transaction processing and data streaming were highly crucial during user sessions. Hyniva identified that the Blue-Green Deployment strategy would be the ideal solution to tackle these challenges.
In Blue-Green Deployment, there are two identical production environments simultaneously running at any given time. This strategy enables seamless delivery of new features to the application with minimized risks and near-zero downtime for the end user. Also, configuration of two production environments allows easier and safer rollbacks in case of errors. Once the configuration was completed, Hyniva performed a test run to demonstrate the process to the client. The Blue-Green Deployment process involved the following steps:
Two Environment Configuration
Labelled current production as Blue and staging as Green for extensive testing without affecting live users.
Quality Assurance Testing
Automated and manual checks in the Green environment to ensure functional parity and performance.
Switch Traffic
Seamlessly switched traffic using Global Accelerator and CloudFront triggered by AWS Lambda.
Monitor & Review
Once the environment switch is completed, the team closely monitored production to ensure smooth user experience and operations. In the event of an issue or disaster recovery scenario, rollback is easily performed by switching traffic back to the Blue environment.
For our client, the Blue-Green strategy was a game-changer for several reasons. As an investment management firm, ensuring their trading platforms and financial services are always available was crucial for strengthening customer trust and loyalty. Data security was enhanced, and transaction processing was further streamlined. The Blue-Green Deployment strategy provided the following advantages:
Fully managed and high availability ensured users could access the applications without interruptions. User sessions are not impacted during switchovers.
Increase in operational efficiency and stability ensured 24/7, 365-day availability.
Business and development teams can now perform extensive testing of new features before deployment to production, drastically cutting down risk and potential disruptions.
In the event of issues or bugs identified in the new deployment, rollback is smoother through simply switching back to the stable Blue environment.
Users are given access to the latest updates and features promptly ensuring high satisfaction and enhanced user experience.
Our client noticed a nearly zero downtime during deployments due to the implementation of automated approvals with GitHub actions, and the automated switch implementation made the switch between environments less than a minute. The streamlined deployment process also enabled nearly 70% faster deployment times, increasing overall productivity and efficiency. In the event of functional bugs, issues, or disaster recovery scenarios, the seamless rollover feature ensures the client can maintain uninterrupted operations for their users with confidence.
The Blue-Green Deployment strategy significantly enhanced our client's operational efficiency. By adopting this strategy, the firm achieved uninterrupted 24/7 access, drastically reduced deployment downtime by nearly 95%, and accelerated deployment times by 70%. The ability to conduct thorough testing of new features and seamlessly roll back if needed further minimized potential risk factors and enabled a seamless user experience with nearly zero downtime. Our client is now also prepared with robust infrastructure to manage and recover from failures, strengthening the resilience of their disaster recovery plan. This successful implementation not only bolstered the firm's reliability but also strengthened our strategic partnership and further cemented Hyniva as a trusted AWS Partner.
