Technology Record - Issue 31: Winter 2023

78 VIEWPOINT Teams at the Center for Internet Security and Microsoft Azure worked together to test CIS Hardened Images for Linux MIA LAVADA: CENTER FOR INTERNET SECURITY Visualising the performance of Linux VMs in Azure Cloud computing carries many benefits for your business, as long as you’re able to ensure the performance and availability of your cloud environments. For example, whilst cloud computing can allow organisations to rapidly scale cloud services, in the absence of performance and availability, you can’t reliably scale your services to fit your needs. This means that your organisation could miss out on taking advantage of certain resources, or it might need to pay for resources it no longer needs for a period of time. Furthermore, poor availability in the cloud means that you can’t count on having cloud-based backups available in the event of a disaster. Even if they are available, poor performance might render those backups incomplete, potentially costing your organisation due to lost data, intellectual property, and so on. An absence of performance and availability can also limit access to innovative technology. If this is the case, organisations can’t use the cloud to adequately experiment with new technology such as artificial intelligence and machine learning. This can provide you with an inaccurate picture of how new technologies work, causing you to lose out by not innovating now. At the Center for Internet Security (CIS), we understand the importance of performance and availability for your cloud environments. That’s why we partnered with the Microsoft Azure team to test CIS Hardened Images for Linux with the Azure Monitor Agent. Visualising performance and availability in Microsoft Azure For context, Azure Monitor is a service that helps you evaluate the availability and performance of your applications and services in Azure. It uses telemetry to provide you with an overview of your applications. With that information, you can proactively remediate issues that undermine the availability and performance of your apps and their dependent resources. Azure Monitor used to employ legacy monitoring agents for data collection, but now the Azure Monitor Agent (AMA) does all that work. First, it gathers data from the guest “Azure Monitor Agent is now validated for successful deployment and overall functionality for a range of CIS Benchmarks”
