The secret of Uber is in its simplicity as it appeals to the basic needs of a human. You don’t need to wait and jostle with others for hailing a ride. Just touch your mobile screen and viola! The taxi is right there where you need it.

No wonder many people want to build an Uber like app i.e. make a copy or clone it. The term Uber Clone became popular, trending in business circles.

What Is An Uber Clone?

It is a taxi booking app software that has all the features of Uber. Plus the customer can have add ons and extensions of their own. What better and faster way to launch an online taxi business than cloning the features of Uber? It saves you lots of time and loads of money too.

Small business owners, entrepreneurs, and startups in their quest to start their taxi business often seem confused on how to go about building an Uber like app.

At Appscrip, we have expertly crafted hundreds of taxi apps with our dynamic and powerful uber clone script. We have put in hours of research on what works in the taxi business and come up with a sterling product which we named KARRY.

Below we discuss the right technology choices we made in order to build an Uber-like app.

Databases Used in an Uber Like App Databases

What databases are recommended for an Uber Script? | SQL or NoSQL Database?

Use NOSQL – Mongo or Cassandra

Which database should I use for lower response time?

In Memory Database Redis or Amazon ElastiCache.

Use REDIS for High availability, Lua scripting, transactions, on-disk persistence, pub-sub system, versatile data structures, cluster support – used as an in-memory data structure store, cache and message broker for operations that require low latency.

Which database provides high fault tolerance, high availability and high performance to build an Uber like app? / How to make a highly scalable Uber app? / Should I enable clustering for databases?

Either of the following can be used –

Horizontally scalable MongoDB cluster with indexing, sharding and replica sets for high performance, fault tolerance and availability as the primary database.

Cassandra for elastic scalability, always-on architecture, fast linear-scale performance, flexible data storage (structured, semi-structured, and unstructured), easy data distribution, transaction support and fast writes support as the secondary database.

What is the most optimal way to send booking requests to the nearest driver (geospatial queries)?

Redis for efficient geospatial queries.

Queuing & Messaging in Uber Like App Queuing & Messaging

How to handle a large number of bookings reliably in an Uber-like app?

We should add a queuing system that acts as the buffer and decouples the sender from the producer of the data. It handles the mismatch in the rate of the incoming booking requests and bookings dispatched to avoid missing dispatch of any incoming booking request, during high volumes of traffic.

Which queuing systems should I use: Apache Kafka or RabbitMQ?

RabbitMQ is an asynchronous messaging broker and queuing system for queuing a large number of incoming booking requests. It provides reliability, including persistence, delivery acknowledgements, mirrored queues, publisher confirms, flexible routing and clustering for high availability.

Apache Kafka must be used as the distributed publish-subscribe messaging system because of its scalability, high volume data handling capability, fault tolerance, reliability, durability, performance, zero downtime extensibility and replication support.

It is ideal for log management systems.

BackEnd API in an Uber Script API Backend

How to develop a fast, low resource consuming, highly performant and scalable backend for an Uber-like app? / Which programming languages are recommended for writing the APIs?

Which is more suitable for writing backend APIs? | Nodejs or Python?

NodeJS – As the primary language for all the Business logic APIs.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Python – For the APIs (heatmaps) which include a large number of data manipulations/computations/crunching operations due to its standard library being large and comprehensive.

How to develop a real-time analytics engine?

Use Apache Flink as the distributed streaming data-flow engine (Realtime analytics)

Apache Spark as the cluster-computing framework (Machine learning)

Python for the analytics dashboard due to its claims to combine remarkable power with very clear syntax and a large set of pre available libraries.

Serverless architecture or cloud deployment?

We can go either way as each comes with its own set of advantages and disadvantages.

Serverless Architecture

Advantage – No pre-assessment of resources required and can auto-scale the resources allocated to the application based on surges in the incoming traffic volume.

Disadvantage – High cost and being a niche technology, it’s hard and expensive to find trained human resources/engineers.

Cloud Deployment

Advantage – Easy to get started due to the availability of a large number of trained resources.

Disadvantage – Pre-allocate the server resources which may lead to under or over-allotment of resources, both of them being dangerous leading to either failed requests due to insufficient resources, or higher price being paid for the resources which are never actually used.

What are the options available for serverless architecture for taxi dispatch software systems?

Amazon Lambda (with Amazon API Gateway) or Firebase Cloud functions.

Payment gateway & Wallet in Taxi app Payment & Wallet

Which payment gateways should I use?

For the MENA region – Payfort

Europe/USA –  Stripe/Braintree.

UK – 2Checkout, Authorize.net, PaymentExpress.

Canada – First Data GGE4, Moneris, PayPal Payflow Link, PayPal Payflow Pro.

How do I secure the transaction in taxi booking app software?

Use a payment gateway or a wallet with 3D Secure authentication enabled. Example – Stripe or Paypal’s Braintree.

Use encryption to store any client payment method/card details on the backend.

Never store any payment method secrets like CVV on the app side and their transmission should be secure and only over HTTPS.

Deployment in an taxi booking software app Deployment

All the backend code is broken into several microservices and dockerized to achieve:

Higher Return on Investment (ROI) & cost savings,

Standardization & productivity,

CI efficiency,

Compatibility & maintainability, simplicity & faster configurations, rapid deployment, continuous deployment & testing, support multi-cloud platforms, isolation and security.

Should I use Docker/Kubernetes to build an Uber like app?

Kubernetes and Docker are both fundamentally different technologies but they work very well together, and both facilitate the management and deployment of containers in a distributed architecture.

Should I use Monolith or Microservice architecture?

A monolithic application will be much easier to build, make changes, deploy, and provide testing. The microservices architecture is more beneficial for complex and evolving applications. It offers effective solutions for handling a complicated system of different functions and services within one application.

Which method should I use for communication between Microservices?

gRPC- For inter microservice communication.
