Recently, we launched the first session of our Microsoft Azure AZ-103 training program. The response we received was very positive and highly motivating. We covered Module 1 – Azure Fundamentals in this session.
- Module 1: Azure Administration
- Module 2: Azure Virtual Machines
- Module 3: Azure Storage
- Module 4: Virtual Networking
- Module 5: Intersite Connectivity
- Module 6: Monitoring
- Module 7: Data Protection
- Module 8: Network Traffic Management
- Module 9: Azure Active Directory
- Module 10: Securing Identities
- Module 11: Governance and Compliance
- Module 12: Data Services
Availability Zones, Regions, Peering, and Domains
The trainer started with the Introduction of Azure Architectural Components such as Fault Domain, Update Domain, Availability Zone, Availability Region, Geography, Peering region, etc.
- Azure Data Centre – RACK, ToRS (Top Of The Rack Switch) to Supply power to Rack
- Each Server Rack (identified as Fault Domain) contains 24 Servers (20 for Customer and 4 for Microsoft for maintenance)
The trainer also resolved all the doubts asked by the students parallelly, in a stupendous way. Also, Eva and Atul left no stones unturned while explaining the students their queries. For more information on how these Architectural Components impact virtual machines, refer here.
How to choose a Region?
An elaborate explanation was given on Region pairs and why they’re paired like that. Apart from that, there are various factors upon which a region is chosen, such as:
- Cost – Price based on Region (slight difference)
- Customer Location
- Data Center Location
- Available Services – not all services are available in all regions
- Compliance – Regional Region, GDPR, HIPPA
Then the instructor chose the topic, Cloud models. Various cloud models such as IaaS, PaaS, and SaaS were explained in great detail. Also, the difference between them was unfolded in a lucid way. Various examples were also given of each cloud model which helped people apprehend them in much faster. Additionally, the shared responsibility model was also discussed in which points were drawn out between Customer Managed and Microsoft Managed services.

Working of Domains
The session also gave a hands-on experience by helping us visualize the steps while signing up for Azure Cloud. It included Enterprise Agreement, Resellers, Solution Partners, PAYG, Students, Free Trial, and Sponsorship. So, how can we interact with Azure Datacenter? And what actually happens in Fault and Update Domains when we access Azure? Answers to questions like these were unraveled. Here are a few key points about them from the session:
- Each Fault Domain (FD) has a Fabric Controller which watches servers in that Fault Domain
- All Fabric Controller connects to Orchestrator
- Orchestrator is also responsible for ATN & ATZ
The next topic to cross from the checklist was How to administer Azure? This included several things such as Azure Portal, PowerShell, Cloud Shell, Resource Manager, and ARM templates. An outline of these rudimentary topics was sketched. A proper run-through of how things worked was captured and explained by the trainer.
Subscription, Resource Group, Resources, and Tags
After that, we covered different topics like subscriptions, resource groups, resources, and Tags.
Here are a few key points from the session:
- A logical collection of resources can be called Resource Group.
- A resource is associated with Resource Group.
- Resource Group is inside a Subscription that in turn belongs to a Management Group.
Virtual Machine Planning & Sizing
This session also covered what a virtual machine is and its configurations. Furthermore, it includes how you should decide what type of Virtual Machine you should deploy. Here are some key concepts from the session:
- Planning Virtual Machine
- How to decide what VM type to provision:
- Is it for test/dev or production?
- Is this for hosting a website?
- What is the purpose of VM?
- Start with Resource Group, decide a network, name of VM, Location of VM (Region, AZ, FD), Size of VM (aks SKU), Pricing Model, Storage attached to VM (O.S. Disk & Data Disk), O.S. (Linux, Windows, etc)
- VM Series (A Series, B & D Series, H Series for HPC, N Series, etc.)
There are several similarities between Oracle and Azure which were also covered in this session:
- Different types of VMs in Oracle Cloud similar to Azure
- A compartment in OCI is similar to Resource Group in Azure
- Policy & Tags are also available in Oracle & Azure.
- VCN in OCI is same as Virtual net in Azure
- FastConnect (Oracle) to Express Route (Azure)
Virtual Machine Disks
In this part, the trainer covered what type of disks we can use in our virtual machines.
- Three different types of disks:
- O.S. Disks
- Temporary Disk for a short time
- Data Disk with SCSI driver
- Another option is Storage Account
- Disk Option: Standard Hard Drive Disk (HDD), Standard Solid State Disk (SSD), Premium Solid State Disk
- Managed & Unmanaged Disk (We’ll look more into Storage Module)
- Supported O.S. Windows, Red Hat Linux, Ubuntu, Suse Linux
Create Virtual Machine using Azure Portal
- Demo creating VM using Azure Portal
- Availability Options: No Redundancy, Availability Zone or Availability Set
- Disks: O.S. Disk & Data Disk
- VM Extension: Backups, Antivirus, CI/CD
We also learned how to connect our Windows Server using RDP & assign web server roles.
Course Outline and topic-wise weightage
A basic overview of the Course Outline was provided. Furthermore, the topic-wise weightage was discussed too which was as follows:
- Subscription & Resources: 15-20%
- Implement & Manage Storage: 15-20%
- Deploy & Manage VM: 15-20%
- Configure & Manage Virtual Networks: 30-35%
- Managing Identities: 15-20%
The duration of the exam will be 3.5 hours (210 minutes). Also, the exam will comprise of 40-50% practical questions, 60-50% theoretical question. And the catch is that in each part, you need to score at least 70%.
In the end, a recap of Day 1 was provided by Atul on these topics: Cloud Vendors, Service Model, Deployment Model, Resource, Resource Group, Subscription, etc. To conclude, it was a very involving and interesting session and we got great feedback.
