What is scalable software design?
Software scalability is an attribute of a tool or a system to increase its capacity and functionalities based on its users’ demand. Scalable software can remain stable while adapting to changes, upgrades, overhauls, and resource reduction.
What are scalable systems?
A system is scalable when it has the capacity to accommodate a greater amount of usage. Scalable systems can handle extra usage, but their capacity varies. Some systems might only scale to handle double the current usage; other systems might scale to handle 1000x the current usage.
What are scalable design principles?
At the simplest level, scalability is about doing more of something. This could be responding to more user requests, executing more work or handling more data. While designing software has its complexities, making that software capable of doing lots of work presents its own set of problems.
How do you create a scalable application?
How to Design Scalable Architecture
- Don’t use vertical scaling.
- Do favor horizontal scaling.
- Don’t default to physical servers.
- Do take advantage of cloud storage.
- Don’t create unnecessary bottlenecks.
- Do consider a microservice architecture.
How do you make a system scalable?
Rules
- Ensure your design works if scale changes by 10 times or 20 times;
- Do not use bleeding edge technologies;
- Optimize the design for the most frequent or important tasks;
- Design for horizontal scalability;
- Design to use commodity systems;
- Design to Leverage the Cloud;
- Use caches wherever possible;
How do you make sure a scalable system?
Scalability Design Principles
- Avoid the single point of failure.
- Scale horizontally, not vertically.
- Push work as far away from the core as possible.
- API first.
- Cache everything, always.
- Provide as fresh as needed data.
- Design for maintenance and automation.
- Asynchronous rather than synchronous.

What are the benefits of scalable systems?
A scalable system should be prepared for a lot more workloads in the future. We can upgrade the servers to larger ones, with more CPUs and memory. We can design the system so that it can be extended by adding more servers to the existing application cluster.
What are the best solutions for horizontal scalability?
Most clustering solutions, distributed file systems, load-balancers help you with horizontal scalability. Royans Tharakan wrote about this on his blog: If you need scalability, urgently, going vertical is probably going to be the easiest (provided you have the bank balance to go with it).
