Scalability


Scalability, Golang

Scalability is a critical aspect of any messaging system. NATS Streaming is designed to be scalable, both horizontally and vertically. This means that it can be deployed on a single server or across multiple servers to handle increasing demand.

Horizontal scalability refers to the ability to add more servers to a NATS Streaming cluster. This can be done to increase the throughput and capacity of the cluster. Vertical scalability refers to the ability to add more resources to a single NATS Streaming server. This can be done to improve the performance of the server.

The scalability of NATS Streaming is a key reason why it is a popular choice for building scalable messaging systems. NATS Streaming can be used to build systems that can handle the high throughput and low latency requirements of even the most demanding applications.

Here are some real-world examples of how NATS Streaming is used to build scalable messaging systems:

  • The New York Stock Exchange uses NATS Streaming to power their market data platform.
  • Netflix uses NATS Streaming to power their video streaming platform.
  • Uber uses NATS Streaming to power their ride-sharing platform.
  • Airbnb uses NATS Streaming to power their home-sharing platform.

These are just a few examples of how NATS Streaming is used to build scalable messaging systems. NATS Streaming is a powerful and versatile messaging platform that can be used to build a variety of scalable messaging systems.

Reliability


Reliability, Golang

Reliability is a critical aspect of any messaging system. NATS Streaming is designed to be reliable, even in the event of failure. It uses a variety of techniques to achieve this, including replication and persistence.

  • Replication: NATS Streaming replicates messages across multiple servers. This ensures that if one server fails, the messages will still be available on the other servers.
  • Persistence: NATS Streaming persists messages to disk. This ensures that if a server fails, the messages will still be available after the server is restarted.
  • Fault Tolerance: NATS Streaming is designed to be fault-tolerant. This means that it can continue to operate even if one or more servers fail.

The reliability of NATS Streaming is a key reason why it is a popular choice for building scalable messaging systems. NATS Streaming can be used to build systems that can handle the high throughput and low latency requirements of even the most demanding applications.
