Google Cloud Armor is a valuable tool for securing cloud resources, but its pricing structure can be a concern. The default URL connected to Cloud Run can bypass Cloud Armor without the use of a load balancer or backend. To effectively utilize Cloud Armor, users must place a load balancer in front of their Cloud Run and ensure they have a backend. This adds complexity to the setup process.

One of the main drawbacks of Cloud Armor is its pricing. The enterprise tier costs €200 per month plus additional expenses, while the standard plan requires paying for everything consumed. This can add up quickly, with the potential for significant monthly bills.

In comparison, Cloudflare offers a more affordable option with its basic tier priced at free and its pro tier at €20. For users who don't require 24/7 support, this is a more budget-friendly choice.

While Google Cloud Armor provides excellent protection against threats like DDoS attacks and SQL injection, its pricing structure may be a barrier for some users. Users must weigh the benefits of Cloud Armor against the costs and consider alternative options like Cloudflare.
