AZ 900 & 104 By Touseef Ahmed
On premises system dis-adv (Space Hardware & costly, Need large IT team, Pwer supply, Down time and high availability issues , No fully utilization of physical hardware)
Vitrualiation - Virtualization allow to divide physical hardware into multiples logical unit. We can creats multiples VM, can increase RAM, CPU, HD.
Two types of virtualization (1. desktop based that need OS, like VMware virtal pc - Hiper-v) (2. No need OS can intsall Directly on hardware, ESXI, Citirix)
Firmware is specialized, low-level software embedded directly into hardware devices, providing essential instructions on how the device operates, communicates, and functions.
What is cloud computing ?
On demand delivery of computer resources over intenet.
Advantage - no space required, no hardware, no large IT team, High availability in anywhere in world, low cost according to use as compare to on premises. Resources ( RAM, CPU, HD) can be increase.
Disadv - Can not be use without internet, require money.
what are public cloud computing platform ?
Public cloud computing platforms are third-party services—such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud—that deliver computing resources like servers, storage, and applications over the internet on a pay-as-you-go basis. They enable organizations to reduce infrastructure costs, access, and scale resources instantly.
what is microsoft azure ?
Microsoft Azure is a comprehensive public cloud computing platform offering hundreds of services, including computing, storage, networking, AI, and analytics, web hosting, File Folder sharing, Data base SQL service.
Azure is used for various purposes, including hosting websites, running backend services, big data analytics, AI development, and secure storage.
What is Azure Administrator Associate (AZ-104) ?
Azure Administrator Associate helps learners to understand practical and conceptual concepts like Azure Storage, Active Directory, Virtual Machines, Web Apps in Azure and Azure Monitor.
AZ Cloud Type of Services
Infrastructure as service (Iaas) - When you use physical hardware resources not software and OS
Plateform as service (Paas) - When you use physical hardware resources including OS not software or data
Software as service (Saas) - When you use physical hardware resources including OS and application software (Mircosoft 365 is example)
below pictures for batter understanding
How to Create Azure Free tier account ? go to Portal.azure.com It will be good if you have outlook/hotmail account. Follow instructions and fill form proceed further.
Introduction of Azure Portal
You can drag drop item to dashborad, click star under all services it will be add in left navigation bar, most options are available in picture.
Azure VM Intro - you can take basic (general purpose) tier for free acoount Max 2 to 8 GB RAM, for paid you can take more power full or standard tier.
GPU VM will be high cpu/Video not RAM, when you need good processor and RAM (high peroformance compute VM) is good option, If you eed good RAM you can choose (memory optimize VM).
Computer optimize similar to GPU but without graphic card. you can add more storage in this VM Storage optimize VM. Check below VM family picture.
Now We will perform 2 labes ICNT Gyan
Lab1 - VM - Windows server 2022 - IIS Webserver- host simplet web page
Lab2 - VM -Windows server - attach data disk SAN storage and configure
Lab3 - VM - Linux - Apache - host web page
Press Virtual Machine
Creats resurce group - VM name without space - Region (optional for now) - Avialability option (no infrastructure for now) - Security standard - image (Chose OS) - Size (chose vm size for now DS1 V2) - Username (admin1/password) - RDP(enable option http - RDP) - press next you will move to disk tab
Disk tab - os disk type choose standard ssd or standard HD - Press next move networking tab
Networking tab - Press next until last tab review creats it will creat VM
Check public IP in VM and try Remote desktop,Manage - Add Role & features - enable IIS & Web role then copy webpage in C drive:/ inetpub -www - and check website
Attaching extra disk to VM
You can attach a disk in existing VM as in lab2 check below picture follow red marks, we have attached 2 disks disk1 and disk2.
Computer it will be appear as unassign you need to configure under disk management, creat simple volume and procees further
VM Image Capturing - VM capturing allow you to save vm copy under image so whenver vm is deleted or any changes made to existing vm then you can restore prevous vm.
Cost Management - Billing - Invoice - here you can check cost used
Make sure you delete VM and Resouce Group when lab is done.
High Availability - Microsoft make sure almost zero down time through high availability. Three method of high availability.
1. Availabilty Set - Microsoft uses Three Rack called Fault domain(FD) and max 20 Servers in each fault doamin(FD) or Rack, When availability set is used it replicate vms horizantally.
if whole datacenter is down then down time, to replace this second option is availability zone.
2. Availability Zone - If you creats VMs in different zones yu may face minor delay accessing data because of different zones.
3.VM Scale set - When one VM is over loaded, azure creats another VM automatically to distribute load but you need to set criteria of load. Similarly it can delete VMs automatically when load is reduced again you needto set duration and load criteria for deletion of extra VMs, this technique called auto scaling.
Azure VNet - A secure, logically isolated private network, representing your own network in the cloud.
Max 1000 Vnet can be Created in a account
Max 3000 Subnet can be created in a vnet
Vnet does not support boradcast and multicast
In all Subnet starting 4, 0 to3 and 255 total 4 ip's are reserved so starting ip will be 10.0.0.4
When two different region's US and India Vnet want to communicate we need to enable global peering.
In a single region multiples Vnet can be created, two different Vnet can not communicate without peering or settings.
In a single Vnet multiples subnet can be created and all those subnet will communicate each other without further setting.
Vnet Lab - We will take 2 regions Central india and East Us, India region will carry 2 Vnet and 3 subnet and each subnet will include a VM, while east US will have 1 Vnet and a subnet with only one VM. Then we will test and make possible communication in between both region using global peering.
Press Virtual Network - then follow instructions given in picture or steps. Creats Mutiples Vnet and Subnet as below according to uper scenario.
Central India side
When you creat VMs for lab follow same steps in basic as in first vm lab then under networking tab make sure you select correct virtual network, subnet then proceed to review creats.
This time when I creat VM under East Us region I will change region as in below picture.
Turn Off firewall of windows or windows server and test ping.
For different Vnet or region communication enabling peering
Click Vnet - seach - Peering - add peering
