Exploring the Cost of Hosting an App on Google Cloud Platform

Are you considering hosting your application on Google Cloud Platform (GCP)? Understanding the costs associated with running an app on GCP is crucial before making any decisions. This article will delve into the various factors influencing the cost, provide examples of pricing, and offer advice on how to estimate your expenses.

Key Components Influencing the Cost

The average price of hosting an app on Google Cloud Platform can vary widely depending on several factors:

Compute Options

Google Cloud Platform offers a range of compute options, the most popular being the Compute Engine and App Engine.

Google Compute Engine Google App Engine

Google Compute Engine pricing is based on the type of virtual machine (VM) you choose, the number of VMs, and the duration they run. Prices can range from a few cents per hour for smaller instances to several dollars per hour for larger instances.

Google App Engine is a platform-as-a-service (PaaS) option where you pay based on the resources your app consumes. Prices typically start at a few dollars per month for small applications and can increase significantly with usage.

Storage

Cloud Storage costs depend on the amount of data stored and the frequency of access. Generally, prices start at around $0.02 per GB per month for standard storage.

Networking

Egress data transfer out of GCP can incur costs, typically starting at around $0.12 per GB after a certain free tier.

Additional Services

Other services like Cloud Functions, Cloud Run, or managed databases such as Cloud SQL and Firestore have their own pricing structures. These are often based on usage metrics including requests, compute time, and storage.

Example Pricing for a Small Web Application

For a small web application, you might expect to pay:

Compute: $20 - $100 per month for a small instance. Storage: $5 - $20 per month for moderate data storage. Networking: $10 - $50 per month depending on traffic.

Overall, a small application could cost anywhere from $30 to $200 per month, while larger applications could easily exceed $1000 per month, depending on the scale and resource usage.

Advice and Tools

To estimate costs accurately, it is advisable to use the Google Cloud Pricing Calculator based on your specific needs. Understanding the architecture needs and the number of users is also crucial. Starting small and scaling later is often recommended.

Database Options

When it comes to databases, Google offers several options:

Google Cloud SQL: A fully managed relational database. Google Cloud Datastore: A NoSQL schemaless database. Google Cloud Launcher: To launch pre-built solutions like MongoDB or ElasticSearch on Compute Engine.

Google Datastore has the advantage of starting at 0 cost and scaling as you go, with around 50,000 operations per day for free.

Other costs include network usage, which incurs an egress charge of $0.12 per GB after a certain free tier. Google also offers dozens of other services, each with its own cost structure. Use the Products and Services page on Google Cloud Platform to find more details.

Scalability

The scalability of Google Cloud Platform is a significant advantage. You can configure load balancers to launch or remove server instances depending on traffic. This makes it easy to manage cost and performance.

For a cost-effective start, consider using the f1-micro instance, which is extremely cheap at around $4 per month. Google’s calculator can help you predict your costs based on how much you plan to scale.

Free Trial and Credits

As a new user, Google Cloud offers 300 credit dollars for a two-month period. This is great for testing and experimenting. As of March 10th, 2023, the 300 credit trial is valid for 12 months, and you can also use a free f1-micro instance.

These free credits and services can significantly help you get started without incurring substantial costs. Take advantage of them to explore the capabilities of Google Cloud Platform thoroughly.
