What is Google App Engine

When selecting the right cloud platform for your business, it’s essential to ensure the success of your web application.

Not only do they ensure that your app can handle the traffic and demands placed upon it, but they can also offer a wide variety of features and support that can make your life as a developer much easier. However, with so many options available, it can be challenging to figure out which is the right fit for your business.

One option that you may not have considered is App Engine. This Google-run platform offers a variety of benefits for both developers and businesses, making it worth taking a closer look at.

In this article, we’ll explore what App Engine is, its features, and some of the pros and cons to help you determine if it’s the right solution for your web application needs.

What Is App Engine?

Google’s app engine, also known as GAE, is a platform that allows users to develop and run applications on Google’s infrastructure.

App Engine can be used for a wide variety of applications, including web applications, mobile backends, and even virtual machines. With security, scalability, and high-performance modules built-in, App Engine is a popular choice for developers who want to focus on code rather than infrastructure.

The Google Cloud market share is 9% worldwide, with this number only set to grow in the coming years. As one of the largest cloud providers, developers can be confident that their applications will be well-supported on App Engine. And with over a decade of experience, GAE is a platform that businesses can trust.

App Engine Advantages

Google App Engine has a number of advantages that make it an appealing platform for developing and running web applications, including:

Uses Google Servers To Power The Platform

One of the most significant selling points of App Engine is that it uses Google servers to power the platform.

By using some of the same hardware that Google uses for its own applications, businesses can be confident that their app will be able to handle any traffic or demand placed on it.

Furthermore, because Google runs the platform, developers can trust that they will have access to the latest features and updates.

Pay-As-You-Go Payment Model

Unsure of how much traffic your app will get? With App Engine’s pay-as-you-go payment model, you only ever pay for the resources that you use.

This can be a great way to save money, especially in the early stages of development when traffic is often low. Whether you’re a small business or a larger enterprise, this pricing model can be flexible enough to meet your needs.

Top-Notch Security and Reporting Systems

Since Google runs App Engine, it benefits from the company’s years of experience in managing data and keeping it secure.

In addition to its robust security features, App Engine also has comprehensive reporting tools that can be used to track the performance of your application and identify any potential issues.

For example, if there is a bug in your code, you can use the App Engine’s logs to track down the problem and fix it quickly.

Easy To Scale

As your company grows and your app becomes more popular, it’s important to have a platform that can easily scale to meet the increased demand.

With App Engine, you can simply add more resources as needed without having to reconfigure your entire infrastructure. This can save a ton of time and hassle from having to move to a new platform as your business grows.

Multiple Built-In APIs

Lastly, App Engine comes with a number of built-in APIs that can be used to add features and functionality to your application.

For example, the Google App Engine Cloud storage API can be used to store and retrieve data, while the Google Cloud Endpoint API can be used to create and manage data entities. These APIs can save you a lot of time and effort from having to develop your own solutions from scratch.

Google App Engine Limitations

Although its a great platform, it has some disadvantages. Some examples, below:

Vendor lock-in

Vendor lock-in is a significant limitation of the Google App Engine as users face data migration issues to other NoSQL databases. Porting applications from one platform to another can be quite a challenge. (1)

Read-only access to the file system

Google App Engine users have to work with read-only file system access, a deterrent for many potential users. It does not allow writing to local files, and data must be stored within a distributed setup. (1)

Not all languages and frameworks are supported

App Engine does not offer support for all widely-used programming languages and frameworks. Users are limited to Node.js, Java, Ruby, C#, Go, Python or PHP languages. Users have to rely on the custom runtimes feature to utilize other languages. (2)

Expensive versus pure IaaS deployment

Google App Engine is an expensive option compared to self-hosted alternatives. It is comparatively pricier than an IaaS deployment, and costs can get higher based on growing requirements. (3)

Customer support is not perfect

Google leaves App Engine users wanting more as its customer support is not perfect. (4)

App Engine Core Features

Now that we’ve gone over some of the advantages of using App Engine, let’s take a look at some of its core features:

Remote Access Through The Cloud Console

The Google Cloud Console is a web-based interface that can be used to manage your App Engine applications.

Through the console, you can deploy and debug your code, set up domain mapping, manage user permissions, and view application logs.

You can also use the console to monitor the performance of your app and identify any potential issues.

Fully Managed By Google

App Engine is a fully managed platform, which means that Google takes care of all the infrastructure and maintenance for you.

This can free up a lot of your time so that you can focus on developing your application. Furthermore, it also means you don’t have to worry about unexpected downtime or server outages.

Compatible With Popular Programming Languages

App Engine is compatible with a number of popular programming languages, including Java, Python, Go, and PHP.

This can make it easy to get started with the platform, as you likely won’t need to learn a new language. In addition, App Engine also supports a number of frameworks, such as Django and Ruby on Rails.

Easy To Deploy With A Quickstart Option

Lastly, App Engine makes it easy to deploy your code with a quickstart option. This feature can be used to automatically generate the necessary configuration files for your application. In addition, App Engine also provides a number of templates that can be used to get your app up and running quickly.

App Engine Pricing

Now that we’ve gone over some of the features of App Engine let’s take a look at its pricing model. As we mentioned before, App Engine uses a pay-as-you-go billing system, which means you only ever pay for the resources that you use.

This can be a great way to save money, especially in the early stages of development when your app is not receiving a lot of traffic. The pricing is different for apps depending on whether you choose the flexible environment or the standard environment.


The App Engine standard environment is a simple way to get started with the platform. It runs with large amounts so data and under heavy loads, which means you can easily build an application that can scale to meet the needs of your business.

The standard environment is also compatible with a number of popular programming languages, making it easy to get started. The standard environment spreads its requests throughout multiple servers in order to meet traffic demands, but your app will still be limited to a single region.

In the standard environment, you’ll be eligible for $300 in free credits along with 28 instances free per day. From there, you’ll be charged based on the amount of usage and instance class.


The App Engine flexible environment is designed for applications that need more control over their runtime and environment.

This includes apps that require a specific language runtime or libraries, as well as apps that need to be able to run on multiple servers.

The flexible environment makes it easy to automatically scale your app up or down based on traffic demands, which can help you save money on computing resources.

In the flexible environment, you’ll be charged based on the resource, amount of usage, and instance class. There is no free trial available for the flexible environment.

App Engine Alternatives

If you’re not sure if App Engine is the right platform for you, there are a number of alternatives that you can consider, including:


Back4App is a cloud-based platform that provides developers with a backend infrastructure for their mobile and web applications.
