English [Auto] Hi in this lecture we'll look at the core as your architectural component. The first I will look at is the concept of Azure Regent and Azure Availability Zones. You can see from this picture here that there are currently 54 regions worldwide. Some are available regions and some are announced region. But currently there are 54 and this is always changing. So just this is just a point in time as well. Within region or you can think of a region as having multiple data centers. Those are really not this within. Within Azure but the other concept that you do need to know for the exam is the concept of availability zones. So if we scroll down over here we see that Availability Zones are physically separate locations within and as your region each availability zone is made up of one or more data centers equipped with independent power cooling and networking. So this is what I meant is within a region there are many data centers but the concept you need to remember for the exam is really a region is made up of a number of Availability Zones which means that within an availability zone here you can see here there could be one or more data centers. And this is not something that is sure this closes and won't be asked on the exam. So on the exam you just need to understand the concept of a region and a concept of an availability zone. The other concept you need to know for the exam is if you can see from this picture is regions are segregated for resiliency so for region goes down the other region won't go is not impacted as well as within a region. You can see that availability Zone 1 2 and 3 are independent. These are if we just for purposes of discussion we say there's one data center in each availability zone while those are segregated to achieve a certain level of resiliency. But if the whole region goes down then all of the availability zones would go down. So for higher availability then you would deploy your infrastructure your solution in multiple regions. So just before we leave this concept we do cover this in another lecture but there's also the concept of zone and on the exam. Make sure that when you read zone that it says availability zone vs. there is another type of zone and this is usually applicable here. This is usually used for pricing and when you transfer data from one region to another. Microsoft has grouped these regions into zones as well so it can get confusing would have. What's the difference between availability zone and a zone. So here's the great DFA Q is availability zone different from zone yes availability zone is different from Zone zone is a geographical grouping of visual regions for building purposes data transfer pricing is based on zone so for example let's look at Zone 1 zone one is made up of multiple regions candidate a central candidate east north Europe and you can see zone 3 is Brazil South. So again if you go back is Canada Central is a region Canada Central has a number of availability zone but also Canada Central has been group for billing but also more for data transfer pricing into zone 1 so that maybe on the exam and that could be a question that would give you some difficulties but remember when you see zone look to see if in front there's availability zone or just about zones and I think that's all for this topic what I wanted to cover next is the last topic for this lecture the concept of Asia reserves groups for that go back to the year your Porto so let me. So let's go look at resource groups again in your dashboard you can type resource groups so resource groups. So what is a resource group. So our resource group in Asia is is a fairly new approach to group a collection of assets and illogical groups for easy or even automatic provisioning monitoring and access control and for more effective management of their cost one benefit or using resource groups is grouping related resources that belong for example to an application that belong to an application together as they share a unified lifecycle from creation to usage and finally D provisioning. Now the other thing that might be on the exam is that the underlying technology that powers resource groups is de jure resource manager or a r m and that might be an example so there's a close relationship between both of these things. So if we just for illustration purposes if currently I have four resource groups let's click on one over here and we hear a subscription and we see our location or region if I click here is now you can see within this resource group these are all the resources that I have that are associated with that. So basically I can manage this as a grouping as opposed to before you have to manage these individually. So that is the purpose of resource groups. And the last thing that I wanted to cover in this lecture is what are some of the benefits. And this could be on the exam. What are some of the benefits by having resource groups by having regions by having Availability Zones and even zones generally. And what's interesting. So for the exam if we go over here and put advisor which is which I will cover in another lecture so advisors a free service from Microsoft that provides best practices. But what's interesting is the four areas that they provide recommendations are really highlighting the four areas that are best used for this. And here we have high availability security performance and costs. So the benefits of these core architectural components is usually falls in these four areas. I'm using regions or availability zones or resource groups because of security or compliance because I want to have a performance or it's related to costs and in many instances it's high availability I'm using multiple regions or multiple Availability Zones. The grouping of resources sometimes is about likes it some costing could be performance and could be manageability so that could be a other aspect as well especially around the resource groups. All right. I think that's solve for this lecture we've covered quite a bit in this lecture. So whenever you're ready you can go to the next one.
