What does API gateway do? . . The diagram below shows the detail. Step 1 - The client sends an HTTP request to the API gateway. Step 2 - The API gateway parses and validates the attributes in the HTTP request. Step 3 - The API gateway performs allow-list/deny-list checks. Step 4 - The API gateway talks to an identity provider for authentication and authorization. Step 5 - The rate limiting rules are applied to the request. If it is over the limit, the request is rejected. Steps 6 and 7 - Now that the request has passed basic checks, the API gateway finds the relevant service to route to by path matching. Step 8 - The API gateway transforms the request into the appropriate protocol and sends it to backend microservices. Steps 9-12: The API gateway can handle errors properly, and deals with faults if the error takes a longer time to recover (circuit break). It can also leverage ELK (Elastic-Logstash-Kibana) stack for logging and monitoring. We sometimes cache data in the API gateway. Over to you: 1) What’s the difference between a load balancer and an API gateway? 2) Do we need to use different API gateways for PC, mobile and browser separately? –  Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): https://bit.ly/3KCnWXq    #systemdesign #coding #interviewtips  .

Key Concepts to Understand Database Sharding.  .  .  In this concise and visually engaging resource, we break down the key concepts of database partitioning, explaining both vertical and horizontal strategies.    1. Range-Based Sharding: Splitting your data into distinct ranges. Think of it as organizing your books by genre on separate shelves.    2. Key-Based Sharding (with a dash of %3 hash): Imagine each piece of data having a unique key, and we distribute them based on a specific rule. It's like sorting your playing cards by suit and number.    3. Directory-Based Sharding: A directory, like a phone book, helps you quickly find the information you need. Similarly, this technique uses a directory to route data efficiently.    Over to you: What are some other ways to scale a database? –  Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): https://bit.ly/3KCnWXq    #systemdesign #coding #interviewtips  .

How does Docker Work? Is Docker still relevant?   Docker's architecture comprises three main components:    🔹 Docker Client  This is the interface through which users interact. It communicates with the Docker daemon.    🔹 Docker Host  Here, the Docker daemon listens for Docker API requests and manages various Docker objects, including images, containers, networks, and volumes.    🔹 Docker Registry  This is where Docker images are stored. Docker Hub, for instance, is a widely-used public registry. –  Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): https://bit.ly/3KCnWXq    #systemdesign #coding #interviewtips  .

Would it be nice if the code we wrote automatically turned into architecture diagrams? I recently discovered a Github repo that does exactly this: Diagram as Code for prototyping cloud system architectures. 𝐖𝐡𝐚𝐭 𝐝𝐨𝐞𝐬 𝐢𝐭 𝐝𝐨? - Draw the cloud system architecture in Python code. - Diagrams can also be rendered directly inside the Jupyter Notebooks. - No design tools are needed.  - Supports the following providers: AWS, Azure, GCP, Kubernetes, Alibaba Cloud, Oracle Cloud, etc.    Github repo: mingrammer/diagrams –  Subscribe to our weekly newsletter to get a Free System Design PDF (158 pages): https://bit.ly/3KCnWXq    #systemdesign #coding #interviewtips  .
