海外TECH	DEV Community	System Design	https://dev.to/adahanu074/system-design-1h4m	System Design“Here s the simple truth you can t innovate on products without first innovating the way you build them Alex Schleifer AirbnbWhat is system design System design is the process of defining the architecture interfaces and data for a system that satisfies specific requirements​ Once your business or organization determines its requirements you can begin to build them into a physical system design that addresses the needs of your customers What is the need of system design “Programming without an overall architecture or design in mind is like exploring a cave with only a flashlight You don t know where you ve been you don t know where you re going and you don t know quite where you are Danny Thorpe It allows us to scale applications and create efficient architectures that are resilient and performant Enables us to communicate effectively and helps in designing an architecture that meets those requirements We can trade offs between scalability cost performance reliability and maintainability It also involves understanding the best practices and architectural patterns to use in order to make the system as robust as possible When designing a system it is important to consider the underlying infrastructure such as databases networks and other services We always needs to consider the design for scalability security System design fundamentals ScalingScalability refers to an application s ability to handle and withstand an increased workload without sacrificing latency ​Two types ​Horizontal Scaling​ adding more hardware to the existing hardware resource pool​Vertical Scaling adding more power to your server MicroserviceMicroservice architecture is a distinctive method of developing software systems that tries to focus on building single function modules with well defined interfaces and operations ProxyA proxy server is a system or router that provides a gateway between users and the internet In other words proxy server is a computer on the internet that accepts the incoming requests from the client and forwards those requests to the destination server CAP TheoremIn computer science the CAP theorem sometimes called CAP theorem model or Brewer s theorem after its originator Eric Brewer states that any distributed system or data store can simultaneously provide only two of three guarantees consistency availability and partition tolerance CAP StorageScalability of your system design highly depends on the way you are storing the data Different types of data storage mechanisms are suitable to manage your data for different use cases of your system to achieve high scalability and better response time Some of the factors affecting the choice of data storage mechanisms are structure of your data query frequency query pattern response time required and scale needed CachingGetting data from in memory cache is much faster than getting the data from database file system remote call to a third party service or generating the data from complex computation File StorageFor handling static asserts like product images for an ecommerce solution videos for a video streaming solution or file in an online directory service like google drive it is ideal use a file storage or blob storage solution The core difference between file or blob storage and databases is in databases you can query on and modify individual fields of database records whereas in file storage you can query on file s metadata and only query or modify the file as a whole Time Series DatabasesA Time Series Database TSDB is a database specifically designed and optimised for time stamped sequential data It is suitable for measurements or events data that is tracked monitored and aggregated sequentially over a period of time Data WarehouseData warehouse is a centralised and consolidated large amount of historical data solely intended to perform queries and analysis this data is derived from a wide range of sources like application logs transactions and user events It s analytics capabilities allow organisations to derive valuable business insights from their data and improve decision making Data LakesData lakes are used when organisations need low cost storage of unformatted unstructured data from multiple sources that they intend to use for some purpose in the future The structure integrity selection and format of the various dataset is derived at the time of analysis by the person doing the analysis at a later point in time in future Relational databaseIt is a collection of data entities with pre defined relationships between them mostly based on their domain language These entities are organised as tables with rows and columns Each column holds a certain kind of data called a field or attribute about the data record and each row represents a collection of related fields attributes of one data record NoSQL databaseNoSQL databases are build for flexible schemas and are recognised for their performance at scale Key difference between NoSQL and relational databases is that NoSQL is for unstructured storage This means NoSQL databases do not have fixed table structures they are schema freeDatabase combinationsIn a modern microservices based application we use a combination of data storage mechanisms Microservices architecture fundamentally supports it as it allows you to choose different databases for different services based on the use cases to be continued …	2023-03-04 17:15:44
