Considering Uber’s modest beginnings, a monolithic design was adequate for its first attempt to enter the ride-hailing industry. Under the Uber Design framework, this monolith enabled payment processing and driver-rider matching with a single product, initially limited to San Francisco.
As Uber’s goals increased and its reach grew worldwide, it became evident that this monolithic strategy had limitations.
Uber made the crucial choice to switch to a microservice architecture when faced with the difficulties of maintaining a monolithic codebase despite fast development. This change promised operational advantages, including autonomous deployments, more distinct ownership, and improved system stability.
Uber’s ecosystem grew to include thousands of microservices, and additional complications appeared and threatened to negate the very benefits that microservices were supposed to bring.
The widespread use of microservices brought about numerous difficulties, such as difficulties with dependency management, higher overhead associated with cooperation, and increased system instability. Uber discovered that the complex web of relationships between services was preventing engineering teams from being as creative and agile as they might be. It became clear that a more organized and controllable approach to microservices was required.
Uber developers set out on a revolutionary quest to improve their architectural paradigm in reaction to the growing complexity of traditional microservices. The end result was the development of the innovative Domain-Oriented Microservice Architecture (DOMA), which aimed to reduce complexity while maintaining microservices’ operational advantages. DOMA began a new phase in Uber’s architectural development by drawing influence from well-established design principles and creative tactics.
A number of fundamental ideas were presented by DOMA with the goal of organizing microservices into coherent, controllable units:
For Uber, the adoption of DOMA produced important advantages for the platform and product teams:

Uber’s Big Data platform has experienced a remarkable transformation in the rapidly evolving technology industry to keep up with the company’s exponential expansion and shifting business needs. Let’s explore the evolution of Uber’s Big Data platform over its many generations, emphasizing the significant turning points, difficulties, and creative solutions that have influenced it.
Traditional relational databases provided the foundation for Uber’s early Big Data venture and its data architecture. An essential part of Uber’s initial iteration of the Big Data platform was data processing and storage, which was handled by MySQL and PostgreSQL. These databases offered a strong basis for organizing structured data, but they quickly proved insufficient for managing the massive amounts of data produced by Uber’s quickly growing business.
It strategically changed its second generation of Big Data infrastructure to focus on the Hadoop ecosystem after realizing the need for a more adaptable and scalable solution. The main storage engine of this transition was the Hadoop Distributed File System (HDFS), which was backed by Apache Spark for data processing, Apache Hive for data warehousing, and Presto for interactive querying.
With this change, Uber was able to get above the constraints of conventional databases and adopt a horizontally scalable architecture that can manage enormous volumes of data.
This app kept using Hadoop in the third iteration of its Big Data platform, but it also included new technologies to improve data processing and storage even further. Hadoop remained the cornerstone, but with the release of Hudi (Hadoop Upserts Deletes and Incrementals), data management achieved a major turning point by enabling incremental updates and cutting down on data latency. Improvements in data modeling and standardization also contributed to the platform’s increased efficiency and streamlined operations.
Uber’s fourth iteration of its Big Data platform is set to leverage various databases and technologies, including real-time databases, NoSQL, and cloud solutions, to enhance efficiency and innovation while continuing to rely heavily on Hadoop. It hopes to open up new options for scalability, dependability, and real-time insights by adopting a hybrid approach to database management.
The Big Data of the Uber platform’s development from the early days of relational databases to the era of distributed computing and cloud-native solutions reflects larger developments in database technology.
Within the framework of Uber Design, Uber remains ahead of the curve and uses data to push commercial success by embracing the appropriate combination of databases and technology at every turn in its path. Uber’s database journey will significantly impact how transportation and other industries develop in the future as it innovates and expands.
Uber’s distributed database, Docstore, processes tens of millions of queries per second and stores enormous amounts of data. It is essential to the company’s numerous microservices. However, Uber encountered difficulties guaranteeing scalability and low latency access as demands rose and complexity increased.
Despite Docstore’s resilience, a number of issues surfaced as demand increased. Conventional approaches to scaling, whether horizontal or vertical, have proven inadequate to handle the increasing demands of the workload. Furthermore, latency problems were made worse by the difference in read and write requests, which called for a more creative caching strategy.
CacheFront Architecture:
CacheFront was designed to minimize the need for significant scalability to improve latency and cut expenses. It guarantees smooth operation and scalability by implementing caching directly into the query engine layer of Docstore. Cache invalidation, adjustable timeouts, and circuit breakers are all included in the design to improve efficiency and reliability.
The architecture of CacheFront incorporates cutting-edge approaches to address challenging caching problems. It uses techniques like adaptive timeouts, negative caching, and cache warming in conjunction with Redis as a distributed caching solution to maximize performance and consistency.
Uber has a 99.9% cache hit rate thanks to CacheFront, which eases the load on the storage engine while handling over 40 million requests per second. This achievement has simplified infrastructure management and improved performance, freeing developers to concentrate on innovation rather than upkeep.
CacheFront will continue to be a vital component of Uber’s infrastructure as it develops, allowing the business to provide flawless experiences to millions of users worldwide.
Uber prioritizes protecting user data, and implementing strong data security procedures is essential to upholding the integrity and confidence of the services offered. Within the framework of Uber System Design, the company uses fine-grained encryption, a complex method that improves access control, retention policies, and encryption at rest, as the cornerstone of its data security policy.
Giving users granular access to data is the foundation of Uber’s data security model. Conventional access control systems frequently limit access to whole tables or databases by functioning at a coarse-grained level. Uber is aware of the necessity for more sophisticated control, though, particularly in a setting with a variety of dynamic data sources.
Uber allows data owners to define access rights down to the column level by implementing fine-grained access control. This helps to protect confidential data while facilitating authorized data usage. Uber uses the features of Apache Parquet to enforce access limits based on preset tags, giving data owners the flexibility to create access policies that meet their unique needs.
Uber’s data security approach is based on data encryption, which adds an additional layer of protection against unauthorized access. The company uses Apache Parquet to implement column-level encryption, going beyond conventional techniques.
This method maximizes security while minimizing performance overhead by encrypting individual data fields rather than the full information. Uber guarantees data security and integrity even in the case of unauthorized access or data breaches by utilizing encryption methods like AES-GCM and AES-CTR.
For the purpose of managing the data lifecycle and regulatory requirements, effective data retention rules are essential. Uber understands the need for adaptable retention policies that meet changing business and legal requirements. It also applies column-specific retention policies, enabling the selective removal of data according to pre-established categories or tags by utilizing Apache Parquet modular encryption, which can meet retention standards with this strategy while reducing data loss and storage expenses.
Furthermore, Uber offers crucial guidelines to improve user account security. To ensure security against potential unauthorized access, users are advised to change their passwords frequently. Maintaining current personal information, including phone numbers and email addresses, is crucial for smooth verification procedures.
Users are also recommended to proceed with caution and adhere to fundamental security protocols, which include not disclosing login credentials, double-checking emails received from Uber, and creating distinct passwords for every account. Users can reduce security risks and have a safer experience on the platform by following these suggestions.
