Executive Summary

Building Data Analytics Solution on AWS

Our Customer

Healthera operates a leading UK healthcare marketplace that provides patients with medicines, healthcare services and products through the largest digital platform of pharmacies and GPs, including national chains and independent providers. The company cooperates with over 1000 pharmacies and GPs and services more than 100,000 patients on a daily basis. Company’s objective is to transform the way healthcare is provided in the UK, from prescriptions to personalized clinical services.

The Obstacles They Faced

Due to dynamic growth of the business the client had a need to develop a data analytics solution which would ensure data driven decision making across their company. The integral requirement, which we were called to implement for this software, was the integration with Tableau Cloud, enterprise-grade solution on the world’s #1 analytics platform.

How We Helped

Our DevOps team developed and implemented a consistent solution’s architecture based on a scalable cloud data warehouse (AWS Redshift); and then established the integration of the whole system with the external data analytics platform (Tableau Cloud).

The Challenge

Evolving Business Demands Require Proficient Analytics Solutions



As the business is constantly extending, the client has a rapidly growing demand for a customized, flexible, and easy-to-use data analytics solution. The solution is going to provide and sustain data driven decision making across the client’s company as well as ensure analytics availability and proficiency. The data-driven influence on decision making processes is aimed to improve the end-user experience on the marketplace and increase customers’ engagement.

Healthera needed a data analytics software that among other things unequivocally had to match the following requirements:

  • be built around scalable and highly-available data warehouse
  • be integrated with Tableau Cloud (cloud data analytics platform)

The Solution

Developing Custom Data Analytics Solution for Data-Driven Decision Making

To accomplish these requirements and develop the solution according to the client’s needs, we came up with the following strategic decisions to implement in the project:

Using of AWS Redshift as the platform’s foundational data warehouse

Redshift is particularly designed and optimized to store and access much larger data sets than traditional write-optimized data bases. This can be up to 128 TB per node, potentially reaching petabytes of data in a cluster. Therefore, Redshift is much more efficient at loading large volumes of data less frequently.

To ensure Tableau integration we launched Windows based EC2 instances in a public subnet with Tableau Bridge desktop client. Data is uploaded into S3 bucket in JSON format from external MongoDB Atlas service. S3 bucket is used as a datasource for Redshift.

Adopting IaC (infrastructure as a code) approach to:

  • automate AWS resource management
  • speed up and automate cloud provisioning
  • reuse code blocks in multiple infrastructures

Cloud infrastructure for this solution is launched on Terraform – an infrastructure as code tool that allows to create, update, and version Amazon Web Services infrastructure. The main reason for using IaC approach is to ensure consistent infrastructure as well as the ability to replicate it in multiple client’s environments (Dev, Stagging (UAT), Production).
