A large cable operator client uses HP Network Automation (HPNA) to manage network devices for voice, video, and data services delivery. As the cable operator’s network continued to grow and diversify, additional drivers and policies were required in order for HPNA to communicate with new and specialized devices.
AWS Config, along with AWS Config Rules, provides a detailed view of the resources deployed within your AWS account and a way to define governance policies to ensure that those resources comply with industry best practices, as well as your company’s internal practices. We will be creating a custom AWS Config rule in this example that uses an AWS Lambda function to evaluate whether the AWS Instances deployed in our cloud are using outdated instance types.
AWS continually makes improvements to the underlying infrastructure powering its cloud and introduces new, more efficient instance types optimized for various workloads. In many cases, the CPU and memory provided by the updated instance type remains the same. Even so, performance of the newer instance type can be much greater than the old one it replaces as underlying hardware and software at AWS is optimized. In many cases the newer instance type also costs less!
