WhatsApp scaled its platform using DevOps best practices like horizontal scaling, load balancing, caching, and content delivery networks (CDN). With these DevOps best practices, WhatsApp has scaled its platform to support over 2 billion active users and provide a highly reliable and available messaging service.
WhatsApp is one of the most popular messaging apps in the world, with over 2 billion active users. To support such a large user base, WhatsApp needs to be able to handle a massive volume of traffic, including messages, photos, and videos. Also, WhatsApp must be highly reliable and available, even during peak usage times.
To achieve this, WhatsApp uses a variety of DevOps best practices. This includes using infrastructure as code to automate the provisioning and management of its infrastructure, using CI/CD to automate the building, testing, and deployment of its software, and using various monitoring and observability tools to monitor the performance and health of its platform.
In this article, we will look closely at the DevOps best practices that WhatsApp has used or is using to scale up its platform, transforming it into the best messaging app. Flow with us.
The Importance of Scaling WhatsApp
WhatsApp is a cross-platform, centralized instant messaging and voice-over-IP (VoIP) application. It allows users to exchange messages, photos, videos, and documents and make voice and video calls. WhatsApp is one of the most popular messaging apps in the world, with over 2 billion active users.
Now, because WhatsApp is a global messaging app with over 2 billion active users, it needs to be able to handle a massive volume of traffic, including messages, photos, videos, and voice and video calls. Also, WhatsApp must be highly reliable and available, even during peak usage times.
To meet these demands, WhatsApp needs to scale its platform. Scaling a platform means increasing its capacity to handle more traffic and users. There are a number of ways to scale a platform, such as adding more servers, using load balancing, and caching.
When WhatsApp goes down, it can have a number of negative consequences for users. For individuals, it can be frustrating and inconvenient to be unable to communicate with friends and family. For businesses, it can lead to lost productivity and revenue.
In addition to these direct consequences, a WhatsApp outage can also have a number of indirect consequences. For example, if WhatsApp is down for an extended period, people may switch to other messaging apps, such as Telegram or Signal. This could lead to a permanent loss of users for WhatsApp.
A WhatsApp outage can also have a negative impact on the economy. For example, a study by the Centre for Economics and Business Research found that a one-day outage of WhatsApp would cost the UK economy £1.3 billion.
By scaling its platform, WhatsApp can ensure that it can continue providing a reliable and high-quality messaging service to all its users.
How WhatsApp uses DevOps Best Practices to scale its platform
WhatsApp uses microservices, caching, load balancing, containerization, and CI/CD as best DevOps practices to scale its platform.
Microservices
A microservices architecture is a software design pattern that structures an application as a collection of loosely coupled services. Each service is self-contained and performs a specific task. Services communicate with each other through well-defined APIs.
WhatsApp uses a microservices architecture because it offers several advantages for scaling:
- Each microservice can be scaled independently. This makes it easier to scale the overall platform because WhatsApp can scale up or down the resources allocated to each microservice as needed.
- Microservices are more resilient to failure. If one microservice fails, the other microservices can continue to operate. This improves the overall reliability and availability of the platform.
- Microservices make it easier to develop and deploy new features. WhatsApp can develop and deploy new features as independent microservices without modifying the entire platform.
Caching
Caching is a technique that stores frequently accessed data in a high-performance location, such as memory or a solid-state drive. This can improve the performance of an application by reducing the number of times it needs to access its database.
WhatsApp uses a variety of caching techniques to scale its platform.
- In-memory caching: WhatsApp caches frequently accessed data in memory for fast retrieval.
- On-disk caching: WhatsApp caches frequently accessed data on disk for persistent storage.
- Distributed caching: WhatsApp uses a distributed caching system to cache data across multiple servers. This improves the scalability of the caching system and allows WhatsApp to cache more data.
Containerization
Containerization is a lightweight virtualization technology that allows multiple applications to run on a single server. Each application is isolated in a container with its own resources, such as CPU, memory, and storage.
WhatsApp uses containerization to scale its platform in the following ways:
- Containers allow WhatsApp to run multiple microservices on a single server. This improves the efficiency of WhatsApp’s infrastructure utilization.
- Containers make it easier to scale WhatsApp’s infrastructure up or down. WhatsApp can add or remove containers as needed.
- Containers make it easier to deploy new features to WhatsApp. WhatsApp can deploy new features as independent containers without modifying the entire platform.
Continuous integration and continuous delivery (CI/CD)
CI/CD is a set of practices that automate software building, testing, and deployment. CI/CD pipelines are triggered whenever a change is made to the code. This allows WhatsApp to release new features and updates to its users quickly and reliably.
WhatsApp uses CI/CD to scale its platform in the following ways:
- CI/CD allows WhatsApp to release new features and updates to its users quickly. This is important because WhatsApp has a large and active user base.
- CI/CD helps WhatsApp ensure the quality of its software. Each change to the code is tested before it is released to users.
- CI/CD reduces the risk of errors when deploying new features and updates.
Content delivery network (CDN)
A CDN is a network of servers distributed around the world. CDNs are used to deliver content, such as images, videos, and static files, to users from a server that is close to them. This reduces the latency and improves the performance of the content.
WhatsApp uses a CDN to scale its platform in the following ways:
- The CDN allows WhatsApp to deliver images and videos to users from a server that is close to them. This reduces the latency and improves the performance of the WhatsApp app.
- The CDN reduces the load on WhatsApp’s servers by delivering static content from the CDN. This allows WhatsApp to focus its resources on delivering messages and other dynamic content.
Load balancing
Load balancing is the distribution of traffic across multiple servers. This can improve the performance and reliability of an application by preventing any single server from being overloaded.
WhatsApp uses load balancing to scale its platform in the following ways:
- Load balancing allows WhatsApp to distribute traffic across its servers. This prevents any single server from being overloaded and improves the platform’s overall performance.
- Load balancing makes WhatsApp’s platform more resilient to failures. If one server fails, the other servers can continue to handle the traffic. This improves the overall reliability of the platform.
In addition, WhatsApp uses a variety of other DevOps best practices to scale its platform, including:
- Infrastructure as code: WhatsApp uses infrastructure as code to automate the provisioning and management of its infrastructure. This allows WhatsApp to scale its infrastructure up or down quickly and easily as needed.
- Monitoring and observability: WhatsApp uses various monitoring and observability tools to monitor the performance and health of its platform. This data identifies and resolves any issues that may arise quickly.
