Node.js makes it easy to do so but I am going to focus on the cloning strategy in this article and explore the built-in tools available in Node.js to implement it. Successfully scaling a big application should eventually implement all three strategies. We need to do a lookup of that information first. For example, maybe we want to partition our users based on their country or language. ![]() Data partitioning requires a lookup step before each operation to determine which instance of the application to use. This strategy is often named horizontal partitioning, or sharding, in databases. We can also split the application into multiple instances where each instance is responsible for only a part of the application’s data. The implementation of this strategy is often not easy and could result in long-term unexpected problems, but when done right the advantages are great. This strategy is commonly associated with the term Microservice, where micro indicates that those services should be as small as possible, but in reality, the size of the service is not what’s important but rather the enforcement of loose coupling and high cohesion between services. #SCALING FFMPEG NODEJS CODE#This means having multiple, different applications with different code bases and sometimes with their own dedicated databases and User Interfaces. ![]() We can also scale an application by decomposing it based on functionalities and services. This strategy is the minimum you should do and Node.js has the built-in module, cluster, to make it easier for you to implement the cloning strategy on a single server. This does not cost a lot in term of development time and it’s highly effective. The easiest thing to do to scale a big application is to clone it multiple times and have each cloned instance handle part of the workload (with a load balancer, for example). There are mainly three different things we can do to scale an application: 1 - Cloning We also scale our applications to increase their availability and tolerance to failure. The workload is the most popular reason we scale our applications, but it’s not the only reason. I cover similar content in video format there. This article is a write-up of part of my Pluralsight course about Node.js. ![]() This article covers all that goodness and more. #SCALING FFMPEG NODEJS FULL#Node’s cluster module not only provides an out-of-the-box solution to utilizing the full CPU power of a machine, but it also helps with increasing the availability of your Node processes and provides an option to restart the whole application with a zero downtime. Node is named Node to emphasize the idea that a Node application should comprise multiple small distributed nodes that communicate with each other.Īre you running multiple nodes for your Node applications? Are you running a Node process on every CPU core of your production machines and load balancing all the requests among them? Did you know that Node has a built-in module to help with that? It’s something that’s baked into the core of the runtime. Scalability in Node.js is not an afterthought. Read the updated version of this content and more about Node at /node-beyond-basics.
