challenges

The client’s faced the following challenges in their work

Legacy software

The application client needed help with was there for quite some time. Lacking any documentation, their in-house team struggled to understand how to operate, deploy, or maintain the software. Recognizing the significance of the problem, they sought external expertise to find a viable solution.

Disaster unreadiness

Unsure of effectively managing the app, the client realized they were also unprepared for potential emergencies. Building a comprehensive disaster plan and step-by-step emergency guides has become a priority.

Reverse engineering

To unravel all the aspects of the system, our team used the Reverse Engineering technique. By studying the app through experimentation and testing, we pieced together a clear understanding of its architecture, functionalities, and dependencies into comprehensive documentation.

//
Team education

Recognizing that each client's team member has their own experience level, we tailored a comprehensive course to bring everyone on the same page. We also improved in-house staff competency by offering hands-on expertise and guidance, enabling them to use unfamiliar technologies confidently.

Security requirements compliance

We established a strong foundation for security compliance, such as PCI DSS, from ground-up infrastructure development to elevating the product with modern solutions like Kubernetes. Configuring access to the Oracle DB and implementing Hashicorp Vault, our experts ensured users' data protection. Additionally, we trained the internal team in handling unsealing procedures, reinforcing the system's robustness.

Why AWS

AWS benefits at a glance

//

Easy to use

AWS is designed to allow application providers, ISVs, and vendors to quickly and securely host your applications – whether an existing application or a new SaaS-based application. You can use the AWS Management Console or well-documented web services APIs to access AWS’s application hosting platform.

//

Cost-Effective

You pay only for the compute power, storage, and other resources you use, with no long-term contracts or up-front commitments. For more information on comparing the costs of other hosting alternatives with AWS, see the AWS Economics Center.

//

Flexible

AWS enables you to select the operating system, programming language, web application platform, database, and other services you need. With AWS, you receive a virtual environment that lets you load the software and services your application requires. This eases the migration process for existing applications while preserving options for building new solutions.

//
