How do you create a highly scalable system?

How to Design Scalable Architecture

1. Don’t use vertical scaling.
2. Do favor horizontal scaling.
3. Don’t default to physical servers.
4. Do take advantage of cloud storage.
5. Don’t create unnecessary bottlenecks.
6. Do consider a microservice architecture.

What requirements are needed to make a service scalable?

Requirements of Scalable Applications

• Performance: First and foremost, the system must operate well under stress with low latency.
• Availability and Reliability: These are closely related and equally necessary.
• Cost: Highly scalable apps don’t have to be unreasonably expensive to build, maintain, or scale.

What is the most important thing you need if you are going to create a web app?

The most important thing when building a web application is of-course the architecture, this can be broken up into 5 subcategories: languages, API, frameworks, integrations and topology.

What are the steps you would take to enhance an app’s scalability and efficiency?

How To Do Efficient Scaling?

• Keep Your Code Clean. It seems to be obvious, but we just can’t neglect to point it out here.
• Leverage 12factor (https://12factor.net/)
• Take Care Of Your Database.
• Prevent Problems With Queries.
• Choose The Right Hosting.
• Track Caching.
• Prepare For Load Balancing.
• Relieve The Backend.

What are some of the design patterns that ensure a scalable system design and a good development experience?

Principles

• Simplicity. of design not only simplifies the scalability but also simplifies development, deployment, maintenance and support.
• Decomposition.
• Asynchronous.
• Loose Coupling High Cohesion.
• Concurrency and Parallelization.
• Parsimony.
• Decentralization/Distribution.

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 ensure scalability?

Scalability Design Principles

1. Avoid the single point of failure.
2. Scale horizontally, not vertically.
3. Push work as far away from the core as possible.
4. API first.
5. Cache everything, always.
6. Provide as fresh as needed data.
7. Design for maintenance and automation.
8. Asynchronous rather than synchronous.

What requirements are scalable?

Scalability requirements are, in essence, a reflection of the organization’s ambition to grow and the need for a solution to support the growth with minimal changes and disruption to everyday activities.
