Performance of web applications mainly depends on two factors: scalability and response time. Considering today’s use demands, any good website should have a short response time. Scalability is the ability of an application to handle an increasing number of tasks. It can also be described as the potential of being enlarged to facilitate growth.
Infusing Scalability into a Web Application
Most web applications comprise three things: database server, the internet, and the application server. Although building a scalable application is not a hard thing, there are a number of things to consider. It may not be that good to invest heavily in full scaling during the early stages of the web app building process. Such an undertaking can be taken into account when the Minimum Viable Product is initially built. If you want to increase the scalability of an existing application, you’ll need help from competent service providers such as Apica Systems, relevant resources, and time.
Ways of Improving Application Performance and Scalability
A simple web application comprises an app server, database server, and the internet. The app server stands alone. It does neither share memory nor disk storage with any other node. It can easily be scaled horizontally. The database server provides storage as well as access scalability. When there is so much data, the app either becomes unresponsive or may have difficulties when leading. The best solution to this kind of a problem is increasing scalability and maintaining high output: vertical scaling, horizontal scaling, and performance tuning.
This happens when several resources are included in one computer system. In this case, the elements of the web app require large physical memory for working on the requests. This issue can only be fixed by equipping the node with larger Memory CPU, I/O capacity or Bandwidth to minimize the sluggishness of the application. This is actually what is referred to as vertical scaling.
Vertical scaling is actually a cheap and simple process because it doesn’t require any changes to the source code of the web application. The main challenge with this approach is that it may not provide a long-term solution since you may not be able to add several resources to a given node.
Performance tuning is all about performing several troubleshooting sessions. And these sessions are about knowing the main product bottlenecks as well as other problems causing a negative impact to the performance. This may include analyzing the configuration settings, refactoring application source code, carrying out various investigative procedures towards various tiers of the app, and implementing the most recent caching strategies.
It happens when several computer systems are involved. They may involve processing user requests as well as increasing app response due to handling/processing requests in parallel. For this case, the single node of the application is divided into several new ones. The boxes can now be differentiated by the shards.
Some of the best ways of improving the response time of bigger scale web applications is separating storage tire into a different node. A simple web application has three things: the application server, database server as well as the internet. In most cases, performance of web applications depends on scalability as well as response time.
