How to scale WebSockets to millions of connections

WebSockets are hard to scale, it's true. The stateful connection that makes them so powerful for two-way realtime communication also makes them tricky to load balance efficiently, but that isn't to say it can't be done. In this video, Alex Booker (@CodeCast) from Ably runs you through the technical challenges scaling WebSockets before outlining the patterns used to scale WebSockets to thousands of concurrent connections and beyond. Theoretically, the approach to system design outlined in this video can scale to millions of concurrent WebSocket connections in a production environment.

Why transportation and logistics apps with realtime updates need elasticity

Elasticity is far from a solved problem – especially for transportation and logistics companies providing realtime updates. Prior to 2006, startups finding sudden success had to drive – often in a hurry – to a store like Best Buy to purchase new servers and support an unexpected surge in users.

What is RabbitMQ Queues Test?

RabbitMQ is one of the most popular open source message brokers. It is designed to provide high availability, scalability and reliability for enterprise level messaging applications. RabbitMQ basically navigates exchanges between a client (producer) and a consumer, who receives these processed messages. Messages are bundled into queues based on their characteristics and adequately processed. This segregation helps organize data much easier and makes alloting similar functions to a single queue.

Handling Massive Fan-out with AWS Lambdas

AWS Lambda is a serverless compute service that allows developers to run their code without having to manage the underlying infrastructure. With Lambda, developers can upload their code and the service takes care of scaling, provisioning, and managing the servers required to run the code. This means developers can focus on writing code and not worry about the underlying infrastructure.

Why data integrity is essential for transportation and logistics companies providing realtime updates

With the rise of online ordering and the growth of delivery, consumers and businesses alike order more packages, expect them faster, and want rapid updates on progress, delays, and changes. Companies providing transportation and logistics services, then, have a compelling reason to add realtime update features to their apps. In other articles, we’ve talked about the broad challenges transport and logistics companies face when providing realtime updates, including scalability and low latency.

Chat and messaging application features: The complete guide for 2023

In the past decade, chat apps have gone from being a disruptive new technology to something we use every day. Today, WhatsApp boasts over 2 billion daily active users, by far the market leader, followed by WeChat with 1.3 billion and Facebook Messenger at just under 1 billion. Chat apps, put simply, are going nowhere. In that time, customers have come to expect a consistent experience across their chat apps – and a core set of functionality has evolved across all major providers.

Why elasticity is essential for sports, media, and entertainment apps delivering realtime updates

Elasticity, as the term implies, is the ability for software infrastructure to stretch and shrink in line with fluctuating usage. Elasticity is important in many contexts – because usage can always fluctuate – but it’s especially important for sports, media, and entertainment apps, which frequently serve user bases that grow and shrink rapidly depending on events, trends, and breaking news.

Why low latency is important for transportation and logistics companies providing realtime updates

The transportation and logistics industries contain much more complexity than the average consumer would guess. When they build apps, they need to provide a simple, intuitive experience supported by a complex and most often unseen system of vehicles criss-crossing neighborhoods, states, and countries, supported by employees and systems working from behind the scenes to orchestrate the processes necessary to make this all work smoothly.
