CompTIA Cloud+ Domain 4 – Operations and Support
Domains of CompTIA Cloud+
CompTIA Cloud+ certification covers five domains.
Domain 1: Cloud Architecture and Design 13%
Domain 2: Security 20%
Domain 3: Deployment 23%
Domain 4: Operations and Support 22%
Domain 5: Troubleshooting 22%
We will be discussing the fourth domain, ‘Operations and Support.
The Operations and Support phase, also known as O&S, focuses on the implementation of the product support strategy, meeting operational performance criteria and material readiness, and providing support throughout the life cycle of the system in the most cost-effective manner possible. The main purpose of the Operations and Support discipline is to support and run your product in a real-world environment. This domain has 22% of the highest weightage, making it an important domain. This domain will provide an overview on topics such as operation status, efficient operation and optimizing cloud environments. It also includes automation and orchestration techniques.
1. Configure logging and monitoring to maintain operational state. In this sub-domain we will learn how to configure logging and monitoring to maintain operational status in a given situation. This domain will give you a deep understanding of logging and monitoring as well as alerting. We will learn about types and collectors in logging. Collectors explain the Simple Network Management Protocol (SNMP), and Syslog whereas the types define access/authentication, system, and application. You will also learn about trending, analysis, severity categorization and audits. Monitoring allows for an in-depth understanding and verification of baselines, thresholds and log scrubbing. It also verifies continuous monitoring activities. Service management tool integration is used to integrate service monitoring tools. Performance monitoring includes application and infrastructure components. It also monitors availability and uptime that meets SLA-defined requirements. Alerting will guide you through common messaging techniques, appropriate responses, policies to categorize and communicate alerts, as well as enable/disable alarms that explain maintenance mode.
2. Maintain efficient operation in a cloud environment. In this sub-domain we will learn how to maintain an efficient cloud environment in a given situation. This course will cover topics such as confirm completion of backups and change management, asset management, patching, the impacts of process improvements on systems, upgrades methods, dashboard, reporting, and other aspects of life cycle management. We will be studying life cycle management and learn about roadmaps, old/current/new version, migrating and upgrading systems, as well as deprecations and end-of-life. While we’ll be learning about Configuration Management Database, (CMDB), in asset management, we’ll also learn about patching. We’ll learn all about features and enhancements, fixes to broken or critical infrastructure, the scope for cloud elements that need to be patched. Hypervisors, VMs virtual appliances, networking components applications storage components, firmware software, policies, n-1 and rollbacks. In upgrade methods, we learn about rolling upgrades, blue-green, canary, active-passive, and development/QA/production/DR. Dashboard and reporting will provide information about tagging and chargebacks, elasticity usage and connectivity.
3. Optimize cloud environmentsThis sub-domain teaches you how to optimize cloud environments for a given situation. This sub-domain will teach you about right-sizing, compute storage, network, placement and device drivers. Right-sizing will teach you about horizontal scaling, vertical scaling and cloud bursting. In compute, you will learn about CPUs and GPUs, memory and containe.
