Exam Tip- Azure Compute Flashcards
What are some key considerations when comparing Azure Compute options?
The key considerations include trade-offs between flexibility and management complexity, with virtual machines offering high customization but requiring more management, while platform as a service services offer less control but require less management overhead.
What is the main advantage of using infrastructure as a service (IaaS) like virtual machines (VMs)?
Infrastructure as a service (IaaS) options like VMs provide high customization and control over the environment, allowing users to configure almost everything but also requiring them to manage everything.
What are scale sets in Azure and what is their purpose?
Scale sets are automatically scaling groups of identical VMs managed together, allowing for horizontal scaling based on application load, facilitated by load balancers for traffic distribution and high availability strategies.
What is the purpose of Azure virtual desktops?
Azure virtual desktops offer a fully virtualized desktop environment hosted on Azure, ideal for scenarios like secure remote work or handling sensitive data centrally while providing remote access to employees.
How do availability sets differ from scale sets in Azure?
Availability sets provide high availability for unique or non-identical VMs within a single zone or data center by spreading VMs across update and fault domains to mitigate failures and ensure availability even during maintenance or hardware issues.
What are the key differences between Azure App Service and Azure Functions?
Azure App Service is ideal for long-running web applications, whereas Azure Functions are event-driven and intended for short-lived applications triggered by external events.
What are Azure Container Instances (ACI) and Azure Kubernetes Service (AKS) primarily used for?
Azure Container Instances (ACI) are suitable for quickly deploying single containers at low cost, while Azure Kubernetes Service (AKS) is designed for complex applications with features like auto-scaling and load balancing but comes with higher management complexity and cost.
What are the trade-offs when choosing between Azure Container Instances (ACI) and Azure Kubernetes Service (AKS) for container deployment?
ACI offers simplicity and low cost but lacks scalability and advanced features, while AKS provides scalability, advanced features, and control but requires more management and comes at a higher cost.
What are some key exam-specific tips regarding Azure Compute services?
Understand the trade-offs between flexibility and management complexity, know the purpose and differences between VM-related services like scale sets and availability sets, be familiar with Azure virtual desktops and the various platform as a service managed compute services like Azure App Service and Azure Functions, and understand the deployment options for containers including ACI and AKS.
How do Azure Compute services align with different workload requirements and management preferences?
Azure Compute services offer a range of options from high customization and control (VMs, scale sets) to managed services with less management overhead (App Service, Functions) and container deployment options (ACI for simplicity, AKS for scalability and advanced features), allowing users to choose based on workload complexity and management preferences.
