Customer Name: Airpay Payment Services

Airpay is India's first integrated omnichannel financial services platform. Airpay has nearly a decade of experience as a payments aggregator. Their financial services platform is used by Consumers, Businesses, Banks and Financial Institutions from all around the world. They collaborate with over 200+ financial institutions and over 1000 business partners worldwide.

Customer's prior infrastructure for its applications was meticulously managed within on-premises servers, housed within the secure confines of Tata Communications' data center. With the aspiration to bolster their operational prowess, Customer has undertaken a transformative migration endeavor aimed at transitioning their current application version while seamlessly integrating novel features onto the AWS cloud platform. Additionally, with a growing customer base and increasing demand for scalable and secure services, the client recognized the need to modernize its infrastructure.

Challenge

Frequent downtime incidents are causing substantial operational disruptions and a significant loss of productivity. On average, each downtime incident lasts approximately 2 hours, leading to an estimated financial loss of $10,000 per hour. This recurring issue results in considerable business impact, necessitating an urgent and effective solution to mitigate these disruptions.

The applications were experiencing high latency issues, with average response times exceeding 200 milliseconds. This negatively impacts user experience and degrades application performance, especially for real-time processing requirements.

The current on-premises infrastructure was facing significant limitations in scalability, impeding its capacity to manage peak loads and increasing data volumes. This results in performance bottlenecks and a heightened risk of service unavailability.

Limited Geographic Reach: On-premises infrastructure was typically limited to a specific physical location, which was the disadvantage for businesses looking to expand globally or serve remote Airpay bases.

Data Security and Compliance: Current security measures need enhancement to effectively counter modern threats. Over the years, we have observed several incidents of data breaches and unauthorized access, highlighting the necessity for more robust security solutions.

Disaster Recovery and Redundancy: There was a lack of disaster recovery plans which led to extended recovery periods and potential data loss during unexpected outages, thereby compromising business continuity and system reliability. Company wanted a minimum recovery point objective and recovery time objective, avoiding any data loss. Maintenance Overheads: Significant maintenance costs and frequent manual interventions required for hardware and software management resulted in increased operational expenses and divert resources away from strategic initiatives. Integration Challenges: Difficulty integrating with modern cloud-based applications and services, limiting the ability to adopt new technologies and innovate at pace.

Solution

After careful analysis and consultation, the decision was made to migrate the client's services and applications to the AWS Cloud using a rehosting approach. This involved lifting and shifting existing workloads to AWS infrastructure without making any significant changes to the underlying architecture.

We have embarked on a comprehensive journey of establishing an end-to-end infrastructure within the Amazon Web Services (AWS) environment. Our primary objective was to create a robust, highly available, and scalable ecosystem that would seamlessly cater to our dynamic business needs.

The end-to-end setup encompassed every facet of AWS services and resources, including but not limited to virtual machines (EC2 instances), storage solutions (Amazon S3, EBS volumes), network architecture (VPC, subnets, security groups), and identity and access management (IAM). Each component was meticulously configured, optimized, and integrated to ensure a cohesive and efficient infrastructure.

Scalability, a core requirement, played a pivotal role in our setup. We meticulously designed our architecture to accommodate both current workloads and future growth. Through auto-scaling groups, load balancers, and performance monitoring, we established a framework that could dynamically adapt to fluctuating demands, ensuring uninterrupted service availability during traffic spikes and resource-intensive tasks.

Through a diligent cost optimization strategy and meticulous management of resources, we have achieved significant cost savings within our AWS infrastructure. Our commitment to fiscal responsibility and operational efficiency has resulted in an impressive reduction in expenditure, amounting to approximately 30-40% in overall cost savings.

To meet and exceed AWS's stringent security criteria, we embarked on a multifaceted security strategy. This encompassed the robust implementation of Identity and Access Management (IAM) policies, the meticulous configuration of network security parameters, the rigorous application of data encryption protocols, and the formulation of a well-defined incident response framework.

Within our network architecture, we crafted secure Virtual Private Cloud (VPC) configurations, deployed Network Access Control Lists (NACLs), and introduced state-of-the-art firewall solutions. These measures were meticulously designed to safeguard against external threats and ensure the secure transmission of data within our AWS environment.

Data, the lifeblood of our operations, received paramount attention. We diligently encrypted sensitive data both in transit and at rest, employing industry-standard encryption methodologies. This practice not only adhered to AWS encryption requirements but also stood as a robust barrier against potential data breaches.

Benefits

With Amazon S3, the intricacies of capacity planning become a thing of the past. Users can now simply pay for their actual usage, receiving transparent billing for their ongoing consumption.

By migrating to the AWS Cloud, the client achieved unparalleled scalability, enabling them to effortlessly handle spikes in user demand and expand their services.

Enhance Operational Efficiency by Liberating Critical Financial and Human Capital from IT Resource Allocation.

Minimized Capital Expenditure - Eliminate the necessity of procuring enterprise backup software and hardware systems. This relieves the obligation of advance capital equipment budgeting and the accompanying financial outlays.

Leveraging AWS's robust security features, the client bolstered the security posture of their infrastructure, ensuring compliance with industry regulations and protecting customer data.

Swift Data Availability for Cloud-Based Restoration - Eliminated the need to track down or retrieve data from physical servers. This is particularly crucial during critical scenarios, such as on-premises data center outages, where numerous applications require simultaneous and rapid restoration. With EC2 instances equipped with High Availability (HA) and Amazon S3, these challenges cease to exist. Data restoration can commence promptly, often within mere hours.
