Week of September 4th

“You’re my blue sky, you’re my sunny️ day.”

Happy Labor Day👷👷🏽‍♀️ Weekend!

Back at the end of July, we decided to re-route course and go back to the basics with AWS Cloud☁️ focusing on the core concepts and principals of the AWS. Despite hitting a temporary obstacle, we subsequently took and passed the AWS Certified Cloud Practitioner certification exam📝 last week. Feeling the need to spread the love❤️ around the Troposphere we decided we should circle 🔵 back to Microsoft’s very popular cloud☁️ offering Azure and focus on the “fundies” or Fundamentals of Azure. Of course, this wasn’t our first time 🕰 at this rodeo🤠🐴. We spent several occasions in the Microsoft Stratosphere☁️☁️ before. The most recent was looking at Microsoft’s NoSQL Azure offerings. This time 🕰 we would concentrate specifically on General Cloud☁️ Concepts, Azure Architectural Components, Microsoft Azure Core Services, Security🔒, Privacy🤫, Compliance, and Pricing💰, Service Level Agreements, and Lifecycles. To obtain such knowledge we would need to explore several resources starting with our first course 🍽 of Azure fundamentals which was an amazing compilation of rich documentation, vignettes🎞 from current and former blue badgers/ Cloud☁️ Advocates Anthony Bortolo, Sonia Cuff, Phoummala Schmitt, Susan Hinton, Rick Claus, Christina Warren, Pierre Roman and Scott Cate and several short labs🧪 that give you free access to the Azure Cloud☁️ and let you implement solutions. For our second course 🍽 we went out to YouTube and found 5 ½ hours ⏳ of goodness 😊 with Paul Browning’s awesome videos on “Microsoft Azure Fundamentals (AZ 900) – Complete Course and then for encore we went to Pluralsight and visited with both Michael Brown and his Microsoft Azure Security🔒 and Privacy🤫 Concepts and with Steve Buchanan and his Microsoft Azure Pricing and Support Options because who can ever get enough of Security🔒 and Pricing💰?

“So, I look in the sky, but I look in vain…Heavy cloud☁️, but no rain🌧”

General Cloud️ Concepts

First, let’s review… What is cloud☁️ computing anyway? There are numerous meanings out there. According to Wikipedia “Cloud☁️ computing is the on-demand availability of computer system resources, especially data storage🗄 (cloud☁️ storage🗄) and computing power🔌, without direct active management by the user. “

It’s really just a catchy name. So, despite contrary to belief Cloud☁️ Computing has nothing to do with the clouds☁️ ☁️ or the weather☔️ in the sky. In simplest terms it means sharing of pooled computing resources over the Internet. And are you ready for the catcher? “that you can rent”. In other words, you pay for what you use. Opposed to traditional computing way where a company or organization would invest in potentially expensive real estate to house owned Compute🖥, Storage🗄, Networking or fancy Analytics.

So now we are faced with the argument Capital expenditure (traditional computing cost model) versus operational expenditure (Cloud☁️ Computing cost model)

Capital expenditure (CapEx) 💰consists of the funds that a company uses to purchase major physical goods or services that the company will use for more than one year and the value will depreciate over time 🕰

Operational expenditure (OpEx) 💰are deducted in the same year they’re made, allowing you to deduct those from your revenues faster.

So, looking from a cost perspective, the cloud☁️ can offer a better solution for a better cost since the cloud☁️ provider’s already has those, so you would benefit from the economies of scale⚖️.

That’s great but let’s leave the expenses to the bean counters. After all we are technologists and we want the best performance and efficient technology solutions. So, what other benefits does Cloud☁️ provide me? How about Scalability ⚖️, Elasticity 🧘‍♀️, Agility 💃, Fault Tolerance, High Availability, Disaster🌪 Recovery and Security🔒.

  • Scalability ⚖️: Cloud☁️ will increase or decrease resources and services used based on the demand or workload at any given time 🕰. Cloud☁️ supports both vertical ⬆️ and horizontal ↔️ scaling ⚖️ depending on your needs.
  • Elasticity 🧘‍♀️: Cloud☁️ compensate spike 📈 or drop 📉 in demand by automatically adding or removing resources.
  • Agility 💃: Cloud☁️ eliminates the burdens of maintaining software patches, hardware setup, upgrades, and other IT management tasks. All of this is automatically done for you. Allowing you to focus on what matters: building and deploying applications.
  • Fault Tolerance: Cloud☁️ has fully redundant datacenters located in various regions all over the globe.
  • High Availability & Disaster Recovery: Cloud☁️ can replicate your services into multiple regions for redundancy and locality or select a specific region to ensure you meet data-residency and compliance laws for your customers.
  • Security🔒: Cloud☁️ offers a broad set of policies, technologies, controls, and expert technical skills that can provide better security🔒 than most organizations can otherwise achieve.

Ok, now I am sold. But what types of clouds☁️ are there?

There are multiple types of cloud☁️ computing services, but the three main ones are:

Infrastructure as a service (IaaS) – enables applications to run🏃🏻on the cloud☁️ instead of using their own infrastructures. Allows the most control over provided hardware that runs 🏃 your applications

Platform as a Service (PaaS)- enables developers to create as software without investing in expensive 🤑 hardware. Allows you to create an application quickly without managing the underlying infrastructure.

Software as a Service (SaaS) – provides answers to desktop needs for end users. Based on an architecture where one version of the application is used for all customers and licensed through a monthly or annual subscription. 

What about Cloud☁️ Deployment models? Well, there are multiple types of cloud☁️ deployment models out there as well.

Public cloud☁️: cloud☁️ vendor that provides cloud☁️ services to multiple clients. All of the clients securely 🔒 share the same hardware in the back end.

Private cloud️: organization uses their own hardware and software resources to achieve cloud☁️ services.

Hybrid cloud️: this cloud☁️ model is a combination of both private and public cloud☁️ models.

Community cloud☁️: this model consists of a pool of computer resources. These resources are available to the different organizations with common needs. Clients or tenants can access the resources quickly and securely🔒. Clients are referred to as tenants.

“Blue skies, smilin’ 😊 at me Nothin’ but blues skies do I see”

So now that we expounded the virtues of Cloud☁️ computing Concepts let’s take a deeper a look on what we came for…

Microsoft Azure is a cloud☁️ computing service created by Microsoft for building, testing, deploying, and managing applications and services through a global network of Microsoft managed data centers.

“Architecture starts when you carefully put two bricks🧱 together. There it begins.”

Azure Architectural Components

Microsoft Azure is made up of data centers located around the globe 🌎. These data centers are organized and made available to end users by region. A region is a geographical 🌎 area on the planet 🌎 containing at least one, but potentially multiple data centers that are in close proximity and networked together with a low-latency network.

Azure divides the world 🌎 into geographies 🌎 that are defined by geopolitical boundaries or country borders. An Azure geography is a discrete market typically containing two or more regions that preserves data residency and compliance boundaries.

Availability sets are a way for you to ensure your application remains online if a high-impact maintenance event is required, or if a hardware failure occurs. Availability sets are made up of Update domains (UD) and Fault domains (FD).

Fault domains is a logical group of underlying hardware that share a common power🔌 source and network switch, similar to a rack within an on-premise data center.

Update domains is a logical group of underlying hardware that can undergo maintenance or be rebooted at the same time 🕰. An update domain is a group of VMs that are set for planned maintenance events at the same time 🕰.

Paired regions support redundancy across two predefined geographic 🌎 regions, ensuring that even if an outage affects an entire Azure region, your solution is still available.

Additional advantages of regional pairs:

  • In the event of a wider Azure outage, one region is prioritized out of every pair to help reduce the time 🕰 to restore for applications.
  • Planned Azure updates are rolled out to paired regions one at a time 🕰 to minimize downtime 🕰 and risk of application outage.
  • Data continues to reside within the same geography as its pair (except for Brazil South) for tax and law enforcement jurisdiction purposes.

Availability Zones are physically separate locations within an Azure region that use availability sets to provide additional fault tolerance.

Resource group is a unit of management for your resources in Azure. A resource group is like container that allows you to aggregate and manage all the resources required for your application in a single manageable unit.

Azure Resource Manager is a management layer in which resource groups and all the resources within it are created, configured, managed, and deleted.

“It is our choices, Harry, that show what we truly are, far more than our abilities.”― J.K. Rowling

Azure Services

Azure provides over 100 services that enable you to do everything from running 🏃 your existing applications on virtual machines to exploring 🔦new software paradigms such as intelligent bots and mixed reality. Below are some of the services available in Azure:

Azure compute 🖥 – is an on-demand computing service for running cloud-based ☁️ applications.

There are four common techniques for performing compute 🖥 in Azure:

  1. Virtual machines – software emulations of physical computers 🖥 .
  2. Containers – virtualization environment for running 🏃 applications.
  3. Azure App Service – (PaaS) offering in Azure that is designed to host enterprise-grade web-oriented applications
  4. Serverless computing – cloud☁️ hosted execution environment that runs 🏃 your code but completely abstracts the underlying hosting environment.

Azure Virtual Machines (VMs) (IaaS) lets you create and use virtual machines in the cloud☁️.

Scaling VMs in Azure

Availability sets is a logical grouping of two or more VMs that help keep your application available during planned or unplanned maintenance 🧹.

  • Up to three fault domains that each have a server rack with dedicated power🔌 and network resources
  • Five logical update domains which then can be increased to a maximum of 20

Azure Virtual Machine Scale⚖️ Sets let you create and manage a group of identical, load balanced VMs.

Azure Batch enables large-scale⚖️ job scheduling and compute 🖥 management with the ability to scale⚖️ to tens, hundreds, or thousands of VMs.

  • Starts a pool of compute 🖥 VMs for you
  • Installs applications and staging data
  • Runs 🏃jobs with as many tasks as you have
  • Identifies failures
  • Re-queues work
  • Scales ⚖️ down the pool as work completes

Containers in Azure

Azure supports Docker🐳 containers (a standardized container model), and there are several ways to manage containers in Azure.

  • Azure Container Instances (ACI)
  • Azure Kubernetes Service (AKS)☸️
  1. Azure Container Instances (ACI) offers the fastest and simplest way to run🏃🏻 a container in Azure.
  2. Azure Kubernetes Service (AKS)☸️ is a complete orchestration service for containers with distributed architectures with multiple containers.

Containers are often used to create solutions using a microservice architecture. This architecture is where you break solutions into smaller, independent pieces.

Azure App Service

Azure App Service (PaaS) enables you to build and host web apps, background jobs, mobile📱backends, and RESTful 😴 APIs in the programming language of your choice without managing infrastructure. It offers automatic scaling ⚖️ and high availability.

App Service, you can host most common app service styles, including:

  1. Web apps- includes full support for hosting web apps using ASP.NET, ASP.NET Core, Java☕️ , Ruby 💎, Node.js, PHP, or Python 🐍 .
  2. API apps – build REST-based 😴 Web 🕸APIs using your choice of language and framework
  3. Web Jobs – allows you to run🏃🏻 a program (.exe, Java☕️ , PHP, Python 🐍 , or Node.js) or script (.cmd, .bat, PowerShell⚡️🐚, or Bash🥊) in the same context as a web 🕸 app, API app, or mobile 📱 app. They can be scheduled or run🏃🏻 by a trigger 🔫.
  4. Mobile📱app back-ends – quickly build a backend for iOS and Android apps.

Azure Networking

Azure Virtual Network enables many types of Azure resources such as Azure VMs to securely🔒 communicate with each other, the internet, and on-premises networks. Virtual networks can be segmented into one or more subnets. Subnets help you organize and secure🔒 your resources in discrete sections.

Azure Load Balancer is a load balancer service that Microsoft provides that helps take care of the maintenance for you. Load Balancer supports inbound and outbound scenarios, provides low latency and high throughput ↔️, and scales⚖️ up to millions of flows for all Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) applications. Azure Application Gateway

VPN gateway is a specific type of virtual network gateway that is used to send encrypted traffic🚦 between an Azure Virtual Network and an on-premises location over the public internet. It provides a more secure 🔒 connection from on-premises to Azure over the internet.

Application Gateway is a load balancer designed for web applications. It uses Azure Load Balancer at the transport level (TCP) and applies sophisticated URL-based routing rules to support several advanced scenarios.

Here are some of the benefits of using Azure Application Gateway over a simple load balancer:

  • Cookie 🍪 affinity.
  • SSL termination
  • Web 🕸 application firewall🔥 (WAF)
  • URL rule-based routes.
  • Rewrite HTTP headers

Content delivery network (CDN) is a distributed network of servers that can efficiently deliver web 🕸 content to users. It is a way to get content to users in their local region to minimize latency.

Azure Storage🗄 is a service that you can use to store files📁, messages✉️, tables , and other types of information.

Disk storage🗄 provides disks for virtual machines, applications, and other services to access and use as they need, similar to how they would in on-premises scenarios. Disk storage🗄 allows data to be persistently stored and accessed from an attached virtual hard disk. 

Azure Blob storage🗄 is object storage🗄 solution for the cloud☁️. Blob storage🗄 is optimized for storing massive amounts of unstructured data, such as text or binary data.

Blob storage🗄 is ideal for:

  • Serving images or documents directly to a browser.
  • Storing files for distributed access.
  • Streaming video 📽 and audio 📻.
  • Storing data for backup and restore, disaster recovery, and archiving.
  • Storing data for analysis by an on-premises or Azure-hosted service.

Azure Files Storage🗄 enables you to set up highly available network file shares that can be accessed by using the standard Server Message Block (SMB) protocol. That means that multiple VMs can share the same files with both read and write access. You can also read the files using the REST 😴 interface or the storage🗄 client libraries 📚

File shares can be used for many common scenarios:

  • Many on-premises applications use file shares.
  • Configuration files 📂 can be stored on a file share and accessed from multiple VMs.
  • Diagnostic logs, metrics, and crash dumps are just three examples of data that can be written to a file 📂 share and processed or analyzed later.

Azure Archive Blob Storage🗄

Azure Archive Blob storage🗄 is designed to provide organizations with a low cost means of delivering durable, highly available, secure cloud☁️ storage🗄 for rarely accessed data with flexible latency requirements. Azure storage🗄 offers different access tiers include:

  • Hot 🥵 – Optimized for storing data that is accessed frequently.
  • Cool 🥶 – Optimized for storing data that is infrequently accessed and stored for at least 30 days.
  • Archive 🗃 – Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements (on the order of hours).

Storage🗄 Replication

Azure regions and geographies🌎 become important when you consider the available storage🗄 replication options. Depending on the storage🗄 type, you have different replication options.

  1. Locally redundant storage🗄 (LRS)- Replicates your data 3x within the region in which you create your storage🗄 account.
  2. Zone redundant storage🗄 (ZRS) – Replicates your data 3x across two to three facilities, either within a single region or across two regions.
  3. Geo-redundant storage🗄 (GRS) – Replicates your data to secondary region that is hundreds of miles away from the primary region.
  4. Read-access Geo-Redundant storage🗄 (RA-GRS)- Replicates your data to a secondary region, as with GRS, but also then provides read only access to the data in the secondary location.

Azure identity services

Identity services will help us in the authentication 🔐and authorization👮🏽‍♂️ of our users. Authentication works hand in hand with authorization.

Authentication🔐 – The act of proving who or what something is

Authorization 👮🏽‍♂️ – Granting the correct level of access to a resource or service

In Azure, authentication🔐 is provided by Azure AD and authorization is provided by role‑based access control.

Azure Active Directory is a cloud-based identity service used in Azure. It used to authenticate and authorize users. When we think Azure Active Directory, think single sign on. Azure Active Directory is not to be equivalent of Active Directory Domain Services used on-premise.

Active Directory Domains Services – full Active Directory Domain Service that we’ve used for years on‑premise.

Azure AD Domain Services (PaaS)- introduced to make it easier to migrate legacy applications as it supports both NTLM and Kerberos for authentication🔐. also supports Group Policies, trust🤝 relationships, as well as several over domain service features.

Azure AD Connect as being like a synchronization tool.

Multifactor authentication involves providing several pieces of information to prove who you are. Microsoft strongly recommends that we use multifactor authentication.

Azure Security🔒 Center reports our complying status against certain standards.

It provides continuous assessment of existing and new services that we deploy, it also provides threat protection for both infrastructure and Platform as a Service services.

Azure Policy is a collection of rules. Each policy we create is assigned to a scope, such as an Azure subscription. When using Azure Policy, we create a policy definition, a policy assignment, and policy parameters,

When we create Azure policies, they can be used by themselves or they can be used with initiatives.  Initiatives are a collection of policies. To use initiatives, we create an initiative definition, an initiative assignment, and initiative parameters

Role Based Access Control (RBAC) is used daily by your organization. It’s central to access control in Azure. Azure provides shared access. RBAC is made up of several different components

  • Roles are groups of permissions that are needed to perform different administrative actions in Azure.  We then assign role members before configuring a scope for the role.
  • Scope details where a role can be used. There are many built‑in roles, each giving different sets of permissions, but three built‑in roles are used more than any other.

Three used most often roles are:

  • Owner role full control of that resource, including the ability to assign other users and group access.
  • Contributor role allows you to do everything except manage permissions.
  • Reader📖 role. This role is read‑only

Always follow the principle of least privilege.

Locks🔒prevent deletions or editing of resource groups and their content Two types Locks 🔒 are Read‑only and Delete.

If you make a resource group read‑only, then all the resources in there can be accessed, but no new resources can be added to the resource group or removed from the resource group.

Delete, then no resources can be deleted from the resource group, but new resources can be added.

Azure Blueprints – advanced way of orchestrating the deployment of resource templates and artifacts.

  • Blueprints maintain a relationship between themselves and the resources that they deployed.
  • Blueprints include Azure policy and initiatives as well as artifacts such as roles.

Azure subscriptions provide you with authenticated and authorized access to Azure products and services and allows you to provision resources. An Azure subscription is a logical unit of Azure services that links to an Azure account, which is an identity in Azure Active Directory (Azure AD) or in a directory that an Azure AD trusts🤝.

An account can have one subscription or multiple subscriptions that have different billing models and to which you apply different access-management policies.

  • Billing boundary. This subscription type determines how an Azure account is billed for using Azure. 
  • Access control boundary. Azure will apply access-management policies at the subscription level, and you can create separate subscriptions to reflect different organizational structures. An example is that within a business, you have different departments to which you apply distinct Azure subscription policies. 

The organizing structure for resources in Azure has four levels: management groupssubscriptionsresource groups, and resources. The following image shows the relationship of these levels i.e. the hierarchy of organization for the various objects

Management groups:

Allow you to apply governance conditions (access & policies) a level of scope above subscriptions

These are containers that help you manage access, policy, and compliance for multiple subscriptions. The resources and subscriptions assigned to a management group automatically inherit the conditions applied to the management group.

Azure offers three main types of subscriptions:

  • A free account
  • Pay-As-You-Go
  • Member offers

There are three main customer types on which the available purchasing options for Azure products and services is contingent, including:

  • Enterprise
  • Web 🕸 direct
  • Cloud☁️ Solution Provider

Options for purchasing Azure products and services

  • Pay-As-You-Go Subscriptions
  • Open Licensing
  • Enterprise Agreements
  • Purchase Directly through a Cloud☁️ Solution Provider (CSP)
Azure free account

The Azure free account includes free access to popular Azure products for 12 months, a credit to spend for the first 30 days, and access to more than 25 products that are always free. 

Factors affecting costs💰

Resource type:

When you provision an Azure resource i.e. Compute🖥, Storage🗄, and Networking, Azure creates one or more-meter instances for that resource. The meters track the resources’ usage, and each meter generates a usage record that is used to calculate your bill.

Services: Azure usage rates and billing periods can differ between Enterprise, Web🕸 Direct, and Cloud☁️ Solution Provider (CSP) customers.


The Azure infrastructure is globally distributed, and usage costs💰 might vary between locations that offer Azure products, services, and resources.

All inbound or ingress data transfers to Azure data centers from on-premises environments are free. However, outbound data transfers (except in few cases like backup recovery) incur charges

Zones for billing purposes

A Zone is a geographical grouping of Azure Regions for billing purposes. the following Zones exist and include the sample regions as listed below:

  • Zone 1 – West US, East US 🇺🇸,Canada West 🇨🇦,West Europe🇪🇺,France Central 🇫🇷 and others
  • Zone 2 – Australia Central 🇦🇺, Japan West 🇯🇵 , Central India 🇮🇳 , Korea South 🇰🇷 and others
  • Zone 3 – Brazil South🇧🇷
  • DE Zone 1 – Germany Central, Germany Northeast 🇩🇪

Pricing Calculator 🧮

The Pricing Calculator 🧮 is a tool that helps you estimate the cost of Azure products. It displays Azure products in categories, and you choose the Azure products you need and configure them according to your specific requirements. Azure then provides a detailed estimate of the costs💰 associated with your selections and configurations.

Total Cost of Ownership Calculator

The Total Cost of Ownership Calculator is a tool that you use to estimate cost savings you can realize by migrating to Azure. To use the TCO calculator, complete the three steps that the following sections explain.

  1. Define your workloads
  2. Adjust assumptions
  3. View the report

Best Practices for Minimizing Azure Costs💰

  • Shut down unused resources
  • Right-size underused resources
  • Configure autoscaling
  • Reserved instances pre‑pay for resources at a discounted rate.
  • Azure cost management provides a set of tools🛠 for monitoring🎛, allocating, and optimizing your Azure costs💰. The main features of the Azure Cost Management toolset include:
  • Reporting
  • Data enrichment
  • Budgets
  • Alerting 🔔
  • Recommendations
  • Price
  • Quotas. place around the resources and the amount of resources that you’re using.
  • Spending limits as your approaching that spending limit, you won’t be able to deploy more resources and not going to go over a budget.
  • Azure Hybrid Benefit Migrate your workloads to Azure, the best cloud☁️ for Windows Server and SQL Server
  • Tags🏷 when deploying resources in Azure, you will want to tag your resources. You can use this to identify resources for chargeback in your organization.

SLAs for Azure products or services

An SLA defines performance targets for an Azure product or service. The performance targets that an SLA defines are specific to each Azure product and service.

  • SLAs describe Microsoft’s commitment to providing Azure customers with certain performance standards.
  • There are SLAs for individual Azure products and services.
  • SLAs also specify what happens if a service or product fails to perform to a governing SLA’s specification.

Service Credits

SLAs also describe how Microsoft will respond if an Azure product or service fails to perform to its governing SLA’s specification.

Application SLA

Azure customers can use SLAs to evaluate how their Azure solutions meet their business requirements and the needs of their clients and users. By creating your own SLAs, you can set performance targets to suit your specific Azure application. When creating an Application SLA consider the following:

  • Identify workloads.
  • Plan for usage patterns.
  • Establish availability metrics 
  • Establish recovery metrics 
  • Implement resiliency strategies.
  • Build availability requirements into your design.

Composite SLA

When combining SLAs across different service offerings, the resultant SLA is a called a Composite SLA. The resulting composite SLA can provide higher or lower uptime 🕰 values, depending on your application architecture.

Service lifecycle in Azure

Microsoft offers previews of Azure services, features, and functionality for evaluation purposes. With Azure Previews, you can test pre-release features, products, services, software, and even regions.

There are two categories of preview that are available:

  • Private preview – An Azure feature is available to certain Azure customers for evaluation purposes.
  • Public preview – An Azure feature is available to all Azure customers for evaluation purposes.

General availability

Once a feature is evaluated and tested successfully, the feature may be made available for all Azure customers. A feature released to all Azure customers typically goes to General Availability or GA.

The Azure updates  page provides the latest updates to Azure products, services, and features, as well as product roadmaps and announcements.

“On the road again…I just can’t wait to get on the road again”
