Driving Scalable Healthcare Solutions for Dr. B. Lal Clinical Laboratory on Amazon EC2 Windows Server
Introduction
Dr. B. Lal Clinical Laboratory (BLAL), founded in 1991, is a premier diagnostic service provider in India with an extensive pathology network offering over 1500+ tests across specialties such as Clinical Pathology, Biochemistry, Hematology, Microbiology, Serology, and Molecular Biology. BLAL delivers doorstep sample collection services and online report accessibility across multiple locations. The organization faced critical challenges in managing secure data, maintaining high availability for patient report access and appointment systems during peak times, and integrating multiple Laboratory Information Management Systems (LIMS) reliably. To overcome these challenges, BLAL partnered with HabileLabs, who conceived and delivered a secure, scalable, and resilient AWS-based solution leveraging Amazon EC2 Windows Server instances as the backbone for their healthcare workloads.
