Describe core Azure architectural components
how many management groups can be supported in a single directory?
10,000
What are the two types of Azure subscription boundaries that consumers can use?
Billing & access control boundaries
why might a consumer of Azure services want to create multiple subscriptions to Azure?
Environments: When managing your resources, you can choose to create subscriptions to set up separate environments for development and testing, security, or to isolate data for compliance reasons. This design is particularly useful because resource access control occurs at the subscription level. Organizational structures: You can create subscriptions to reflect different organizational structures. For example, you could limit a team to lower-cost resources, while allowing the IT department a full range. This design allows you to manage and control access to the resources that users provision within each subscription. Billing: You might want to also create additional subscriptions for billing purposes. Because costs are first aggregated at the subscription level, you might want to create subscriptions to manage and track costs based on your needs. For instance, you might want to create one subscription for your production workloads and another subscription for your development and testing workloads. Subscription limits: Subscriptions are bound to some hard limitations. For example, the maximum number of Azure ExpressRoute circuits per subscription is 10. Those limits should be considered as you create subscriptions on your account. If there's a need to go over those limits in particular scenarios, you might need additional subscriptions.
Describe the 'management groups' level of an Azure subscription
These groups help you manage access, policy, and compliance for multiple subscriptions All subscriptions in a management group automatically inherit the conditions applied to the management group
What is an access control (in regards to a Azure subscription)
This billing model allows you to manage and control access to the resources that users provision with specific subscriptions you can create separate subscriptions to reflect different organizational structures. Example: within a business, you have different departments to which you apply distinct Azure subscription policies.
true or false? If you delete a resource group, all resources contained within it are also deleted.
True
which services primarily use availability zones?
VMs, managed disks, load balancers, and SQL databases
What is a region?
a geographical area on the planet that contains at least one but potentially multiple datacenters that are nearby and networked together with a low-latency network
what is an invoice section?
a line item on the invoice that shows the charges incurred that month. For example, you might need a single invoice for your organization but want to organize charges by department, team, or project.
Describe the 'resource groups' level of an Azure subscription
a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed
what is an Azure resource? Give some examples of Azure resources
a manageable item that's available through Azure -Virtual machines (VMs) -storage accounts -web apps -databases -virtual networks
what is a zonal service? Give an example
a service that pins the resource to a specific zone example: VMs, managed disks, IP addresses
what is a zone-redundant service? Give an example
a service where the platform replicates automatically across zones Example: SQL Database
how can consumers use availability zones to run mission-critical application sand build high-availability into their application architecture?
by co-locating your compute, storage, networking, and data resources within a zone and replicating in other zones (there may bea cost to duplicating your services and transferring data between zones)
how do you set up multiple invoices within the same billing account?
create additional billing profiles. Each billing profile has its own monthly invoice and payment method.
What is a billing boundary (in regards to a Azure subscription)
determines how an Azure account is billed for using Azure You can create multiple subscriptions for different types of billing requirements. Azure generates separate billing reports and invoices for each subscription so that you can organize and manage costs.
Describe the 'subscriptions' level of an Azure subscription
groups together user accounts and the resources that have been created by those user accounts Organizations can use subscriptions to manage costs and the resources that are created by users, teams, or projects For each subscription, there are limits or quotas on the amount of resources that you can create and use
Describe the Resources level of an Azure subscription
instances of services that you create, like virtual machines, storage, or SQL databases
What are some benefits/uses of resource groups?
logical grouping (ie manage and organize your Azure resources) life cycle management (If you delete a resource group, all resources contained within it are also deleted. you might try an experiment and then dispose of the resource group (which deletes all the resources related to the experiment)) Authorization (ie a scope for applying role-based access control (RBAC) permissions. By applying RBAC permissions to a resource group, you can ease administration and limit access to allow only what's needed)
what are containers that organize subscriptions called?
management groups
what are availability zones?
physically separate datacenters within an Azure region that is made up of one or more datacenters (equipped with independent power, cooling, and networking)
Where are resources created?
regions ie, different geographical locations around the globe that contain Azure datacenters
Why would you want to ensure your services and data are redundant?
so you can protect your information in case of failure
what is a region pair? What purpose does the pairing serve?
the pairing of an Azure region with another region within the same geography (such as US, Europe or Asia), and at least 300 miles away allows for the replication of resources (such as VM storage) across a geography that helps reduce the likelihood of interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages that affect both regions at once. If a region in a pair was affected by a natural disaster, for instance, services would automatically failover to the other region in its region pair.
what is the minimum number of zones within a single region?
three
how are availability zones connected?
through high-speed, private fiber-optic networks
true or false? All subscriptions within a management group automatically inherit the conditions applied to the management group
true
how many levels of depth can a management group support?
up to six levels
Azure services that support availability zones fall into which two categories?
zonal services & zone-redundant services
