Media files are uploaded to object storage. <a href=\"https:\/\/www.mirrorfly.com\/blog\/webrtc-video-chat-app-faq\/\">Voice\/video calling relies on WebRTC<\/a> with a signaling server. <\/p>\n<\/div>\n\n\n\n<p><strong>1. Chat Application<\/strong><\/p>\n\n\n\n<p>Initially, a user sends messages or uploads images or makes a WhatsApp call from his Android\/ iOS\/ web platforms. The app maintains a persistent <strong>WebSocket<\/strong> connection with the messaging server to receive real-time communication updates.<\/p>\n\n\n\n<p><strong>2. Authentication<\/strong><\/p>\n\n\n\n<p>When a user logs in, the authentication service verifies his identity and provides a secure <strong>access token<\/strong>. The API Gateway or Messaging Server validates this token before processing the chat app\u2019s requests.<\/p>\n\n\n\n<p><strong>3. API Gateway<\/strong><\/p>\n\n\n\n<p>This<strong> <\/strong>entry point routes requests to the right backend services. It handles <strong>access token validation<\/strong>, rate limiting, request validation, and logging. The token validation at this layer happens on the <strong>HTTP upgrade request<\/strong>, before the WebSocket connection.<\/p>\n\n\n\n<p><strong>4. Real-Time Messaging Server<\/strong><\/p>\n\n\n\n<p>Here, persistent WebSocket connections with the user are established. Whenever the user sends a message, the server processes the request, identifies the recipient, and delivers the message without waiting for another HTTP request.<\/p>\n\n\n\n<div class=\"note-wrapper\">\n<h5> Note: <\/h5>\n<p> WhatsApp uses a custom XMPP-based protocol for its chat connections. However, WebSocket is also a widely used choice for clone apps. Know the difference between <a href=\"https:\/\/www.mirrorfly.com\/blog\/xmpp-vs-websockets-instant-messaging-protocol-comparison\/\">XMPP and WebSocket to decide the best one for your chat app development.<\/a> <\/p>\n<\/div>\n\n\n\n<p>Token validation at this layer happens <strong>per-message<\/strong> or per-session. This confirms the connection remains authorized after the initial handshake.<\/p>\n\n\n\n<p>The messaging server manages typing indicators, online presence, read receipts, delivery acknowledgments, and message synchronization.<\/p>\n\n\n\n<p><strong>5. Messaging Workflow<\/strong><\/p>\n\n\n\n<p>The outgoing message follows a sequence when reaching the recipient. This sequence ensures messages remain reliable even under an unstable network.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Encrypt the message<\/li>\n\n\n\n<li>Validate the sender&nbsp;<\/li>\n\n\n\n<li>Generate a unique message ID<\/li>\n\n\n\n<li>Publish the event to Kafka<\/li>\n\n\n\n<li>Persist the message in database<\/li>\n\n\n\n<li>Deliver it to recipient<\/li>\n\n\n\n<li>Update delivery and read status<\/li>\n\n\n\n<li>Retry delivery (if the recipient is offline)<\/li>\n<\/ul>\n\n\n\n<p><strong>6. Database &amp; Media Storage<\/strong><\/p>\n\n\n\n<p>The database stores user profiles, messages, groups, contacts, and metadata. As the user base grows, databases often use <strong>replication <\/strong>and <strong>sharing<\/strong> to distribute data across multiple nodes and improve scalability.&nbsp;<\/p>\n\n\n\n<div class=\"did-you-know-wrap\">\n<summary> Pro Tip <\/summary>\n<p> Chat platforms continuously generate large data volumes. So developers should optimize indexing, partitioning, and query performance from the beginning. <\/p> \n<\/div>\n\n\n\n<p>Images, videos, voice notes, and documents are uploaded to dedicated object storage instead of the messaging database. The server stores only metadata and file URLs while the actual media resides in cloud storage.<\/p>\n\n\n\n<p><strong>7. Presence &amp; Synchronization<\/strong><\/p>\n\n\n\n<p>This layer continuously tracks user availability including online status, typing indicators, last seen timestamps, and active devices.<\/p>\n\n\n\n<p>It synchronizes unread messages, conversation history, and message status across multiple devices to ensure consistent user experience.<\/p>\n\n\n\n<p><strong>8. Push Notification<\/strong><\/p>\n\n\n\n<p>When the recipient is offline, the messaging server forwards notification requests to <strong>Firebase Cloud Messaging <\/strong>or<strong> <\/strong>Apple Push Notification Service. Once the user connects, the unread messages are synchronized from the backend.<\/p>\n\n\n\n<p><strong>9. End-to-End Encryption<\/strong><\/p>\n\n\n\n<p>Before the message leaves the sender&#8217;s device, it is encrypted using encryption keys. The messaging server routes encrypted data without accessing its contents. This architecture ensures user conversations remain private.<\/p>\n\n\n\n<p><strong>10. Scaling The Architecture<\/strong><\/p>\n\n\n\n<p>As the user base grows, a single messaging server is not sufficient. A <a href=\"https:\/\/www.mirrorfly.com\/enterprise-instant-messaging-software.php\">production-ready messaging solution<\/a> distributes traffic across multiple app servers using <strong>load balancers<\/strong>.<\/p>\n\n\n\n<p>Technologies such as <strong>Redis<\/strong> support caching and session management. The message brokers such as <strong>Kafka <\/strong>\/<strong> RabbitMQ<\/strong> process events asynchronously.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Tech_Stack_is_Recommended_for_Developing_a_WhatsApp_Clone_App\"><\/span><strong>What Tech Stack is Recommended for Developing a WhatsApp Clone App?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The tech stack you choose is important when creating a chat app. It influences server connection status, message syncing, and database scalability. The wrong choice would lead to server crashes, data loss, and slow down the chat experience.<\/p>\n\n\n\n<p>We listed our recommended frontend and backend technology in this section. This will help you <a href=\"https:\/\/www.mirrorfly.com\/blog\/how-to-build-an-instant-messaging-app\/\">build a stable instant messaging app<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1.
