Google Cloud VPC best practices

Google’s Virtual Private Cloud (VPC) is a seamless, high-performance global virtual network that is flexible and scalable, providing networking functionality to compute engine virtual machine instances. With VPC, you can create and run a virtual machine that mimics a physical computer system. In this blog post, we have tried to collate the best practices that need to be followed to make the best use of Google VPC.

Getting started with Google VPC basic practices

  • Establish decision-makers, timelines and groundwork to address all stakeholder needs.
  • Identify VPC network design at the initial stage itself. Keep the network topology design simple to ensure a robust architecture is built for future incremental workloads.
  • Use standard naming conventions that are authentic, instinctive and consistent to better understand the intend and location of resources, along with how it is differentiated from others.

Additional key considerations to implement as best practices

  • Addresses and subnets
  • Use custom subnets for your VPC networks.
  • Collate different apps into subnets with wider address ranges.
  • Single and shared VPC network
  • Have one VPC network for common resources.
  • Get a common VPC for different working groups.
  • Subnet level should have network users.
  • Get single host projects in case of several network interfaces.
  • Get multiple host projects in case you need unique administration policies.
  • Creating multiple VPC networks
  • Design unique VPC networks on a project basis to map them with quotas.
  • Every autonomous team should have a unique VPC network with shared services.
  • Different projects should have different VPC networks to enable independent controls for IAM.
  • Connecting multiple VPC networks
  • Opt for a VPC connection based on your budget and performance needs.
  • Leverage network peering in case resource limits won’t get exceeded.
  • Have external routing to avoid communication through private IP.
  • Control traffic between different networks with cloud interconnect.
  • Get shared services for VPC if different networks need access to the same resources.
  • Hybrid designs
  • Get dynamic routing wherever possible
  • Get connectivity VPC networks for scaling the architecture in multiple networks.
  • Network security
  • Avoid external access.
  • Set stringent security goals.
  • Create perimeters to safeguard sensitive data.
  • Leverage native firewall rules whenever possible.
  • Automate the monitoring of security policies when you use tags.
  • Get additional security tools for protecting your apps.
  • NAT and DNS
  • Get private DNS zones to resolve names.
  • Get cloud NAT for external IPs.
  • API access
  • Get explicit routes to modify the default ones.
  • Get default internet gateways wherever possible.
  • Use Google API instances on a common subnet.

Best practices would help you leverage Google VPC to its full potential with the objective of realizing significant ROIs and smooth workload performance and management on cloud.
