Large scale web applications can effectively achieve high performance irrespective of the number of people using it any given moment in time. It can effortlessly handle large volumes of data, and adapt to voluminous load changes without impacting the quality of operations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That being said, let us explore some of the characteristic features of scalable web apps:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>\u0627\u0644\u0623\u062f\u0627\u0621:<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0Whether it is hundreds, thousands, or millions of users transactions per second, large-scale applications can handle voluminous user requests on applications easily.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Distributed:<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0Large-scale applications are distributed with servers that are geographically closer to users, leveraging CDNs. In absence of data centers, you can run in the cloud.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Data:<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0Deal with a large volume of data and with lots of data types such as customer behavior tracking, page views, logs, products, orders, and more.

The need for scaling<\/strong><\/h4>\n<p><b> <\/b><span style=\"font-weight: 400;\">Scaling<\/span><span style=\"font-weight: 400;\"> is an arduous and expensive exercise. If you intend to add new features to your system, or make the existing ones more sophisticated, you need to make sure that the current functionality can handle the changes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Ensure that your expectations of scaling justify the expenses. How do you find out whether a large scale web application is necessary for your business? Here are a few questions to help you decide:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Do you expect an increase in the number of users? If yes, what percentages are you looking at, and what is the timeframe?<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">How long can you current customer\/user base fit the server you currently use?<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">What storage plan do you use? Is it flexible enough to accommodate size changes?<\/span><\/li>\n<\/ul>\n<h4><b>2. Metrics to define scalability challenges<\/b><\/h4>\n<p><b> <\/b><span style=\"font-weight: 400;\">Once you\u00e2&#8364;&#8482;re clear that your application needs to be scaled, the next step is to decide what scalability issues you need to focus on. Track the following metrics to get a complete picture:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Use of CPU.<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0This is a basic and essential metric that can be measured by most app-monitoring tools. High CPU usage suggests that your app is\u00c2\u00a0 experiencing performance issues.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Use of memory.<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0This is calculated per each process that happens in your app and then aggregated into a single execution.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Network Input\/Output.<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0This is the time spent on sending data from one tracked process to another. Look for instances that consume the most time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Disk Input\/Output.<\/b><span style=\"font-weight: 400;\">\u00c2\u00a0This is all the operations that happen on a physical disk. And it\u00e2&#8364;&#8482;s another process attributed to time\u00e2&#8364;&#8221;while your app is reading data from a file, the CPU is on standby.<\/span><\/li>\n<\/ul>\n<h4><b>3. App monitoring tools<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">\u00c2\u00a0The first aspect of building scalable web apps, is to choose the right app-monitoring tools. These tools can identify problems\/bottlenecks which hinder your ability to scale, and enable you to resolve them on time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some examples include <\/span><span style=\"font-weight: 400;\">AppDynamics, Stackify Retrace, and New Relic AMP. <\/span><span style=\"font-weight: 400;\">Once you choose a tracking tool, perform tests for the above-mentioned metrics. If any of them show high results, you need to dig deeper into the problem and create test cases to scale your app.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These initial results are your benchmarks. Hold onto the tool you choose to keep tracking the metrics during and after developing a large-scale app.<\/span><\/p>\n<h4><b>4. Infrastructure<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Using a <a href=\"https:\/\/searchcloudcomputing.techtarget.com\/definition\/Platform-as-a-Service-PaaS#:~:text=Platform%20as%20a%20service%20(PaaS,software%20on%20its%20own%20infrastructure.\" rel=\"nofollow noopener\" target=\"_blank\">PaaS<\/a> for a web app is recommended because cloud services take care of many aspects involved in web app development and maintenance. These aspects include the infrastructure and storage, servers, networking, databases, middleware, and runtime environment.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you don\u00e2&#8364;&#8482;t yet use a PaaS, consider the following options:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Amazon Web Services Elastic Beanstalk: It automatically handles deployment details including capacity provisioning, load balancing, auto-scaling, and application health monitoring.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Heroku: It always knows what\u00e2&#8364;&#8482;s going on with your applications owing to built in monitoring of throughput, response times, memory, CPU load, and errors.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">IBM Cloud PaaS: It helps you modernize existing applications, embed additional security, and develop new apps for digital initiatives.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Microsoft Azure PaaS: <\/span><span style=\"font-weight: 400;\">It is a <\/span><b>complete development and deployment environment in the cloud<\/b><span style=\"font-weight: 400;\">, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.<\/span><\/li>\n<\/ul>\n<pre><strong>SEE ALSO: <\/strong><span id=\":eo.co\" class=\"tL8wMe EMoHub\" dir=\"ltr\"><mark>Choosing the Right Technology Stack for Web application development <\/mark><\/span><\/pre>\n<h4><b>5. Architecture<\/b><\/h4>\n<p><b> <\/b><span style=\"font-weight: 400;\">The choice of an architecture pattern depends on your app\u00e2&#8364;&#8482;s unique requirements. The most commonly used architectures are listed below:<\/span><\/p>\n<h5><strong>1. Layered architecture<\/strong><\/h5>\n<p><span style=\"font-weight: 400;\">This architecture consists of multiple layers, and a database at the foundation, as the name suggests. Each layer has a specific task, and data usually travels from top to bottom.<\/span><\/p>\n<p><strong>Pick this architecture if you need to develop:<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">new apps within a limited time frame<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">apps that require strict standards in maintenance and testing<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If your business leverages traditional IT processes or have developer teams that lack a strong understanding of different architectures, layered architecture is the ideal choice.\u00c2\u00a0<\/span><\/p>\n<h5><strong>2. Event driven architecture<\/strong><\/h5>\n<p><span style=\"font-weight: 400;\">This architecture consists of a central unit along with modules that interact with data, which is specific to them. When an event triggers the central unit, it delegates the data to the dedicated module.<\/span><\/p>\n<p><strong>Event-driven architecture is most suitable for:<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Developing asynchronous systems<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">User interfaces <\/span><\/li>\n<\/ul>\n<h5><strong>3. Microkernel architecture<\/strong><\/h5>\n<p><span style=\"font-weight: 400;\">This type consists of a core system and plug-in modules that offer additional features and specialized processing to enhance the core functionality. A simple example of such architecture would be\u00c2\u00a0<\/span><a href=\"https:\/\/www.twine.net\/find\/web-developers\/with\/wordpress\" rel=\"nofollow noopener\" target=\"_blank\"><span style=\"font-weight: 400;\">WordPress<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><strong>Microkernel architecture is most suitable for:<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">apps that have a wide target audience<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">instances where you can clearly distinguish between basic and higher needs<\/span><\/li>\n<\/ul>\n<h5><strong>4. Micorservices architecture: <\/strong><\/h5>\n<p><span style=\"font-weight: 400;\">Microservices is an architectural style that structures an application as a collection of services that are<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Highly maintainable and testable<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Loosely coupled<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Independently deployable<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Organized around business capabilities<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Owned by a small team<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The microservice architecture enables rapid, frequent and reliable delivery of large, complex applications.
