First, it is still safe to mention that fast cloud computation for a heavy-duty web application consists of optimizing various aspects of your application's infrastructure and architecture to ensure it can handle a large number of users and data processing efficiently. If your business needs web apps that should handle a massive influx of users’ requests then these tricks are for you too because no one loves to lose their valuable time.

What Is Cloud Computing?

Cloud computing refers to the delivery of computing services over the Internet by providing access to a wide range of resources and capabilities without the need for local infrastructure.

In essence, it allows users to utilize and manage computing resources as a utility which is similar to electricity or water supply.

Key characteristics and components of cloud computing include:

✅On-Demand Service

✅Broad Network Access

✅Resource Pooling

✅Rapid Elasticity

✅Measured Service

Cloud computing services are typically categorized into three primary service models:

1. Infrastructure as a Service (IaaS): IaaS provides virtualized computing resources over the internet. Users can rent virtual machines, storage, and networking infrastructure, allowing them to build and manage their own virtualized environments.
2. Platform as a Service (PaaS): PaaS offers a higher level of abstraction than IaaS. It provides a platform that includes not only infrastructure but also development tools and services. Users can focus on developing and deploying applications without managing the underlying infrastructure.
3. Software as a Service (SaaS): SaaS delivers fully functional software applications over the Internet on a subscription basis. Users can access and use software applications hosted by the service provider without needing to install or maintain them locally.

Cloud computing can be deployed in various deployment models:

1. Public Cloud: Resources are owned and operated by a cloud service provider and made available to the general public. Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
2. Private Cloud: Resources are dedicated to a single organization and can be hosted on-premises or by a third-party provider. Private clouds offer more control and security but may involve higher costs.
3. Hybrid Cloud: Combines public and private cloud resources by allowing data and applications to be shared between them. Hybrid clouds offer flexibility and can help organizations balance cost, control, and scalability.
4. Multi-Cloud: Involves the use of multiple cloud providers to avoid vendor lock-in, enhance resilience, and optimize cost and performance.

Cloud Computing alone doesn’t work efficiently if the following speed-boosting techniques are not properly adopted for your web app.

Here are some key steps to achieve fast cloud computation for your web app by avoiding recurring mistakes:

1. Lazy Loading:

Users don’t love to use web apps that need more internet resources as well as time to load web content so you can implement lazy loading for images and other non-essential resources. Load them only when they come into the user's view so it can effectively reduce initial page load times.

✅Benefits:

• Faster initial page load.
• It conserves bandwidth because it avoids unnecessary downloads of assets that users may never see if they don't scroll down the page.
• Servers experience reduced load because they don't need to process and deliver all assets at once.
• Users can start interacting with the visible content of the page sooner.
• The amount of data that needs to be transferred over the network during the initial page load.
• It can benefit search engine optimization (SEO) by prioritizing the loading of important content first.
• Even if the overall page load time remains the same, lazy loading can make the perceived latency lower.

Essentially, a heavy-duty web app requires loading mandatory features to meet users’ demands and it should be carefully considered otherwise users might get distracted. Here is a well-working example that uses the React Lazy Load component.

This technique has been already deployed into some of the popular platforms like Google Image, Bing Image Search, etc. You can just scroll down the pages of the search result to see loaded and unloaded images on the page.

Also, it's time to avoid those old img tags and embrace the future with picture tags. Picture tags are like having a conversation with your browser. Let it know about the types of images you have and allow it to choose the best one to download based on the device's screen size and supported formats. You can do it as follows:

<picture>
   <source srcset="/media/examples/alternate-image-240-200.jpg"
      media="(min-width: 800px)">
   <img src="/media/examples/alternate-image-298-332.jpg" />
</picture>

2. Right Cloud Provider:

There are so many online cloud providers to offer cloud computing for your service but sometimes, it is challenging to pick the best-suited providers for you. You should select a cloud provider that offers the necessary computing power and scalability for your application. Popular options include AWS, Azure, IONOS Cloud Compute Engine, Google Cloud, and others. Assess your specific requirements, budget, and the provider's services before making a decision.

3. Prefetching:

You can use browser prefetching to load critical resources in the background while the user interacts with your site and it is also a proven fact that faster load times assist higher conversion rates to enhance the user experience. This anticipates their needs and makes your app appear faster.

For your reference, you can use the attribute rel="prefetch" which is used in HTML to instruct the browser to prefetch a resource (such as a script, stylesheet, image, or other asset) in the background. It helps to improve the perceived performance of your web application by loading resources before they are actually needed. Here's how to use rel="prefetch" guide from a well-organized resource.

4. HTTP/2 and HTTP/3:

If your server supports it, enable HTTP/2 or HTTP/3 for faster and more efficient data transmission. These protocols reduce latency and improve page load times. The dynamic duo of faster web surfing!

Is your server feeling a bit old-fashioned and trudging along at a snail's pace? It's time to switch to the superheroes of data transmission: HTTP/2 and HTTP/3!

Imagine HTTP/2 and HTTP/3 as the Flash and Quicksilver of the internet, whizzing around at lightning speed to fetch your web content. When your server supports these protocols, it's like giving your website a rocket-powered surfboard.

HTTP/2 and HTTP/3 have a secret power: they reduce latency which is a fancy word for "waiting around." Nobody likes waiting. These protocols make your website load faster than a squirrel on caffeine😁.

So, if you want your users to have a web experience smoother, enable HTTP/2 or HTTP/3. It's like upgrading your old bicycle to a turbocharged sports car but for your website. Fasten your seatbelts, folks, because your web pages are about to take off like a rocket to the moon!

5. Content Delivery Network (CDN) Fine-Tuning:

Optimize your CDN settings for your specific use case. Experiment with cache settings and edge locations to maximize content delivery speed like playing with LEGO blocks, but for faster websites! In simple words, imagine your website as a giant LEGO castle. Now, the CDN is your secret stash of LEGO pieces that you use to build that castle even faster! Here's the deal: CDNs are like magical teleporters for your web content. But to make them work like a wizard's spell, you've got to fine-tune those CDN settings. It's like adjusting the turbo boosters on your spaceship😉! It's about ensuring that your CDN works harmoniously with your web app to deliver content efficiently.

Here's what you need to do:

✅Cache Settings: Adjust the cache settings to strike the right balance between serving fresh content and reducing server load. Proper caching ensures that frequently accessed content is readily available to users and it enhances page load times.

✅Edge Locations: Consider the geographical distribution of your users and strategically place edge locations. The goal is to minimize the physical distance between users and content delivery servers to reduce latency and improve the overall speed of content delivery.

In the world of web development, CDN fine-tuning is your superpower—like having the ability to build LEGO castles in seconds and make them teleport wherever you want.

6. Resource Minification and Bundling:

You can minify and bundle CSS and JavaScript files to reduce the number of HTTP requests and decrease load times. Think of it as tidying up your digital closet. Just like you bundle and compress clothes to make your wardrobe more efficient, minifying and bundling CSS and JavaScript files assists your web app’s performance.

Here's the drill:

✅Minify: This is like getting rid of all the extra fluff in your code. Unnecessary spaces, comments, and line breaks are trimmed away to keep only the essential instructions.

✅Bundling: Imagine you have a bunch of small packages to send. Instead of mailing them one by one, you gather them into a single, more substantial parcel. Bundling does just that for your CSS and JavaScript files to reduce the number of HTTP requests your website needs to make.

So, while it might not be as exciting as organizing your closet, resource minification and bundling are the digital techniques that assist your web app to perform faster and more efficiently. Less waiting, more speed!

7. Progressive Web Apps (PWAs):

Turn your web app into a PWA to provide an app-like experience, including faster load times, offline capabilities, and smoother performance. Transform your standard web app into a PWA using the mighty library like Workbox library.

Why settle for ordinary when you can offer your users an extraordinary experience?

Here's what Workbox brings to the table:

✅Faster Load Times: Say goodbye to slow-loading pages. PWAs with Workbox ensure swift and efficient loading, so your users can dive right into your app without frustrating delays.

✅Offline Capabilities: With Workbox, your PWA isn't afraid of going offline. It caches essential resources by allowing your app to function even when there's no internet connection. It's like having a trusty backup generator for your digital world.

✅Smoother Performance: Workbox optimizes your PWA's performance by making interactions buttery smooth. Users won't even notice the transitions between online and offline modes – it's that seamless.

8. Service Workers:

Utilize service workers to cache assets and enable offline access. It improves the perceived speed of your web app.

You can do it by using a library like Workbox and here is an example for service workers in a JavaScript application.

import { registerRoute } from 'workbox-routing';
import { CacheFirst } from 'workbox-strategies';
import { CacheableResponsePlugin } from 'workbox-cacheable-response';

const pageStrategy = new CacheFirst({
  // Put all cached files in a cache named 'pages'
  cacheName: 'pages',
  plugins: [
    // Only requests that return with a 200 status are cached
    new CacheableResponsePlugin({
      statuses: [200],
    }),
  ],
});

This code configures a caching strategy for pages using the CacheFirst strategy and the CacheableResponsePlugin.

9. Browser Caching:

You can use browser caching by setting appropriate cache headers for static assets. The best way is to use browser HTTP caching to improve the performance of your web app by reducing the need for redundant downloads of resources like images, stylesheets, and scripts. Browser caching allows the client's browser to store and reuse these resources so that it assists in achieving faster load times and reduced server load.

Here's how to utilize browser HTTP caching:

✅Setting Cache-Control Headers:

Cache-Control: public, max-age=3600

✅Cache-Busting Techniques:

<link rel="stylesheet" href="styles.css?v=2023-09-06">

10. Content Delivery Strategy:

Implement intelligent content delivery strategies to serve content from the nearest server location to the user. This approach aims to minimize latency which is the delay between a user's request for a web resource and its delivery.

The key elements of content delivery strategy involve:

11. Adaptive Images:

To deliver a seamless user experience across a variety of devices, it's crucial to employ adaptive image techniques. These strategies involve using responsive design principles to serve images of the right size and format based on the user's device capabilities.

Here are some techniques:

✅Image Scaling: Create multiple versions of an image in various resolutions and sizes. Use CSS media queries to determine the user's viewport size and load the appropriate image version. So, it prevents users from downloading unnecessarily large images on smaller screens.

✅Srcset Attribute: HTML's srcset attribute allows you to specify multiple image sources with different resolutions. Browsers can then choose the most suitable image based on the user's device characteristics. For example:

<img src="small.jpg" 
     srcset="small.jpg 300w,
             medium.jpg 600w,
             large.jpg 1200w"
     sizes="(max-width: 600px) 100vw, 50vw">

✅Picture Element: The <picture> element provides more control over adaptive images. It allows you to define multiple sources and media conditions to choose the best image source for different scenarios, including varying screen sizes and resolutions.

<picture>
  <source srcset="small.jpg" media="(max-width: 600px)">
  <source srcset="medium.jpg" media="(max-width: 1200px)">
  <img src="large.jpg" alt="An adaptive image">
</picture>

13. Database Sharding:

If your web app involves heavy database usage, then it is better to consider sharding your database to distribute the load across multiple servers for faster query performance and cloud computing as well.

Essentially, database sharding is a database architecture technique used to partition data across multiple database servers or shards. It is primarily employed to improve the scalability and performance of web applications.

14. Edge Computing:

It is a distributed computing approach where certain processing tasks are executed closer to the data source or user rather than relying solely on centralized servers in a remote data center. This concept brings computation to the "edge" of the network which is closer to where it's needed most—your users. Imagine your web app as a grand performance, and your servers as backstage crew members. Edge computing allows some of those crew members to move closer to the stage by allowing the show to run smoothly and without delays.

Here's how it benefits your web app:

• Reduced Latency

• Bandwidth Savings

• Enhanced Reliability

• Scalability

15. Connection Pooling:

Let's have a look into caching. It’s a web optimization technique that's like a secret stash of your web files stored in a lightning-fast vault.

Here's the lowdown:

📥What is Caching?

Caching is the art of preserving a snapshot of your web files in a special storage haven known as a cache. It's a bit like having a quick-access drawer for your favorite snacks – everything's ready for munching without the hassle of fetching it from the pantry.

📥Why Cache?

Enabling browser caching offers various of benefits:

• Bandwidth Bliss: Caching reduces the need for repetitive resource downloads, saving precious bandwidth.
• Speedster's Paradise: With cached files, your web pages load faster than a ninja on roller skates, delivering a seamless user experience.
• Latency Lightened: Users experience reduced waiting times, thanks to cached content being served swiftly from their local device.
• Server Stress Relief: Less frequent server requests mean a lighter workload for your server, leaving it cool, calm, and collected.

📥A Word of Caution

But wait, there's a trade-off: caching means you'll essentially have two versions of your website at any given time. While this isn't usually an issue for static content, it can pose challenges for real-time services reliant on up-to-the-minute data accuracy.

✅The Solution?

Fear not! Even for real-time services, cache strategies can be fine-tuned to clear specific cache subsections when new data arrives, keeping your information fresh and accurate.

In the world of web optimization, caching is your trusty sidekick, boosting performance and user satisfaction. It's all about delivering the goods faster and smarter!"

16. Data Caching:

Implement data caching at the application level to store frequently accessed data in memory by reducing the need for repeated database queries.

17. Content Compression:

Compress text-based responses using gzip or Brotli compression to reduce the amount of data transferred over the network. Also, you might prefer to check this well-instructed guide.

18. Distributed Content Delivery:

You can use multiple cloud regions for distributed content delivery to ensure global users experience low-latency access.
