摘要
IPAM and Workload VPC Provisioning Automation
Pushka, a principal SRE, presented an overview of IPAM (IP Address Management) and its integration with workload VPC provisioning, including recent enhancements. The session covered the benefits of IPAM, its architecture, and a demo of the automated VPC provisioning process.
IPAM automates IP address management, eliminating manual intervention and reducing errors. It uses Infoblox grid, which consists of containers and IP addresses, and includes extensible attributes (metadata) for each IP address, such as owner, company, and status. The current workload VPC approach is automated, using IPAM YAML files that specify parameters like business contact, engineering contact, and parent CIDR. We don't need to worry about IP address. If it's beyond IP address is 22 or greater, then only we need to take the approval. Availability Zone IDs (az id) are used instead of names (az name) to avoid inconsistencies.
Enhancements include provisioning multiple VPCs, email notifications, additional CIDR support, non-routable IP address support (using 10.2.0.0/16), and approval requirements for /22 or smaller CIDR blocks. Overlapping IP addresses are prevented by Infoblox grid, which manages all IP addresses. A demo showed how to provision a VPC, including the justification process for larger CIDR blocks. So we just need to put the information at the right place and everything will work.
The approval process for CIDR blocks smaller than /22 involves submitting a justification that is reviewed by the network team. If approved, the VPC provisioning proceeds; otherwise, it fails. Email notifications are sent to the user and the network team throughout the process. Infoblox maintains a list of provisioned IPs against each AWS account, accessible via the Infoblox grid interface. The Infoblox architecture includes a master database in a Houston data center, with redundant systems for DNS, NTP, and DHCP services.
