Among the main issues identified with the current infrastructure were the following:

• Applications had poor performance during peak loads, which frequently resulted in customers not being able to access services.
• Some applications were reliant on resources that were expected to be decommissioned.
• Some of the software infrastructure had become complex with unknown interconnections between applications that were not going to be sustainable over the long term.

Accordingly, after considerable research and internal exercises, WorldRemit engaged with SoftServe as an AWS Partner to conduct both a feasibility study and further specific tasks under the AWS Migration Acceleration Program (MAP).

It opted to conduct this migration of its application over three designated phases:

Assess: During this phase, SoftServe, as the AWS Partner, performed a client migration readiness assessment to identify the capabilities required in the migration and build a TCO model for the client’s migration project.

Mobilize: This phase accelerated the client's migration decisions by providing clear guidance on migration plans, including proofs of concepts (PoCs) — such as small-scale projects for customers that might have not fully committed to adopting AWS. These determined the feasibility of the AWS solution and verified that solutions would function as envisioned, leading the customer to commit to using AWS for the migration if the PoC was successful.

Migrate and Modernize: Finally, this phase was focused on the execution of the large-scale migration plan developed during the mobilize phase.

INITIAL CHALLENGES

One of the main issues to overcome was the complexity of the solution — documentation that was not up to date for the current architecture, client organization complexity, and frequent previous changes that had been dictated by business needs.

By February 2023, SoftServe completed the first two phases of MAP for WorldRemit, including completion of the assessment phase within six weeks. During this exercise, SoftServe delivered an analysis that identified which applications should be decomposed or decommissioned.

VALUE DELIVERED

SoftServe supported the client in their AWS Cloud migration journey by moving the core solution engine into AWS Cloud. This produced several benefits for the digital payment company, which ultimately led to increased business value.

Firstly, unified cloud and tech stacks across their payment solution resulted in improved collaboration and communication between teams, resulting in increased productivity and faster development times. This enabled them to innovate and introduce new features and functionalities faster, ultimately leading to a competitive advantage.

Secondly, cloud migration of the core payment solution improved scalability, which enabled WorldRemit to handle increased transaction volumes during peak periods without performance handicaps. This resulted in improved efficiency and reduced downtime, ultimately leading to higher revenue and lower operating costs. Previously, a one-hour outage had resulted in $40k of extra costs.

Thirdly, reducing outages and increasing reliability led to increased satisfaction for the 8 million clients, who were then able to send money for 46% cheaper than average bank transfers within a couple of minutes. This, in turn, is expected to enable the client to enjoy higher customer retention rates and the scalability to increase the number of customers.

Finally, it avoided potential losses of $100 million that could have been incurred if virtual resources on the original cloud provider had to be decommissioned. This would have led to the suspension of their services for end-users for approximately three months.

By utilizing SoftServe’s technology skills to unify the cloud and tech stack across their payment solution, and moving the core solution engine into the cloud, WorldRemit improved reliability, scalability, and efficiency. The company significantly increased customer satisfaction and established the platform for the next phase of growth.
