The world of cloud computing is changing rapidly, and developers must keep up with the latest technologies. This article will look at how to build a scalable web application that can be scaled down without losing data when you are not using it. We will also dive into basic web design and development resources and tools like Google’s APIs for Natural Language Processing (NLP) and Text Understanding and some tips on debugging your applications in the cloud.

1. Creating Your Infrastructure With Docker

Docker is a platform for building, shipping, and running distributed applications. It uses a client-server architecture to provide isolated processes on a Linux system. This allows you to package an application with all its dependencies into a standardized unit for software development. The Docker container wraps up the application and any other dependencies into one easy-to-run package that can be moved around your infrastructure securely without worrying about compatibility issues or libraries being out of date because they’re all being shared across containers. The Docker hub is a valuable resource for learning more about Docker for those interested.

Another benefit of using Docker containers is that they are lightweight compared to traditional virtual machines (VMs). You can run multiple instances on one machine efficiently without impacting performance too much since each container has minimal overhead required by the host operating system (OS). Also, depending on how much memory was allocated during creation time, it might take longer before reaching total capacity since they share resources now instead of having dedicated ones like VMs do!

2. Big Data and Analytics with Google Cloud

Google Cloud Platform is a collection of cloud computing services that include:

  • Google Compute Engine – a web service for deploying and running virtual machines on the Google Cloud Platform.
  • App Engine – a platform for building and hosting web applications entirely in Google Cloud.
  • BigQuery – a scalable managed data warehouse for analytics across massive datasets.

Google Cloud Datastore is a scalable, fully managed NoSQL database service based on the same technology as Amazon SimpleDB. You can store and query data in real-time using SQL or GQL (the native language of Datastore). It’s built to enable interactive queries on your data at any scale while retaining strong consistency guarantees and high availability in case of failure. This lets you build applications that respond quickly to changing user demand without sacrificing reliability or performance.

3. Speech API

Speech API is a browser-based speech recognition API. It can convert audio from your application into text and do something with it. This can be useful for many reasons, such as adding voice control to your app or helping people who cannot type on a keyboard, like those with disabilities.

Speech API is currently available in Chrome and Firefox. You can use it with any of these browsers by typing “speech” in the search box and clicking “Speech Recognition” when you find it. Once you have done that, there will be a dropdown menu where you should select “Try this out.” On doing so, an input box will appear, which allows you to speak into it and get results back immediately.

4. Natural Language API, Translate API

Today, we will look at the Natural Language API and Translate API. Both APIs enable you to extract information from text by using the structure of sentences. For example, you may want to build a bot that can read and understand content written in a natural language such as English or Spanish and then make decisions based on what it has read.

The Natural Language API lets users extract text information by using sentence structure. You can use this API to define entity types (for example, Person, Location, etc.), intent schema (i.e., intents like “get” or “booking”), and actions associated with each intent type (i.e., action name). Then you can query your bot with natural language queries like “I want to book my flight.” This will trigger your bots’ intent which will match with any of them and help you take appropriate actions based on the user’s intent type(s).

5. Debugging and Troubleshooting in the Cloud

Debugging and troubleshooting allow you to identify and resolve problems with your application. Once you have deployed your web application, it is essential to be able to debug any problems that arise during operation.

There are several ways that you can debug your code:

  • Viewing logs in the Cloud Console or through the command line interface (CLI).
  • Using a REST API call.

The end goal is to identify the cause of any errors and fix them.


As you can see, many ways to build scalable and reliable web applications in the cloud exist. This article has covered some of the most common methods, but we hope it gave you a good idea of the options available. The key takeaway is that you have many different tools when building an application, and it’s up to you to decide which will work best for your project.
