Best practices and design considerations
In this section, we will look at some VPC best practices and design considerations that you need to factor in when designing and building your secure network on Google Cloud. From an exam perspective, it is important to understand these as you will find questions about best practices.
VPC best practices
For VPC, some of the best practices include the following:
- Prevent overlapping IPs and control subnet creation by creating VPC networks using custom subnet creation mode.
- Reduce management and topology complexity by making use of Shared VPC where possible.
- Group similar applications into fewer, more manageable, and larger subnets.
- Apply organization policies to do the following:
- Skip the creation of default networks for new projects.
- Restrict shared VPC host projects and subnets.
- Restrict VPC peering usage.
- Ensure the design scales to your needs by considering the limitations of each network component.
