Designing Large-Scale Systems: Building Blocks

The Art of Scaling: Crafting Large-Scale Systems for Tomorrow’s Challenges

FigureI-Building blocks of a large-scale system

Today’s large-scale systems must be robust enough to handle increasing demand, flexible enough to adapt to changing requirements, and resilient enough to recover from failures. This article will explore five critical components that form the backbone of such architectures:

• Data Storages
• Services
• API Layer
• Security
• Observability

Each of these elements is pivotal in constructing a resilient and scalable system capable of supporting modern business needs.

Let’s begin our discussion with the Data Storage component, depicted on the right side of the above image (Figure I).

Data Storages

Every business relies on data, whether it’s customer information, internal stakeholder information, transaction records, or operational metrics. This data must not only be securely stored but also made accessible to various teams across the organization and potentially to external partners or applications.
