What is an IT Migration?

An IT Migration is basically a movement of data or software from one system to another. Also, depending on the complexity of the project, an IT migration involves data migration, application migration, operating system (OS) migration, and others.

A typical migration project usually involves the movement of data too, which is called – Data Migration. Here is the definition of data migration from Wikipedia.

Data migration is the process of selecting, preparing, extracting, and transforming data and permanently transferring it from one computer storage system to another. Additionally, the validation of migrated data for completeness and the decommissioning of legacy data storage are considered part of the entire data migration process.[1][2] Data migration is a key consideration for any system implementation, upgrade, or consolidation, and it is typically performed in such a way as to be as automated as possible, freeing up human resources from tedious tasks. Data migration occurs for a variety of reasons, including server or storage equipment replacements, maintenance or upgrades, application migration, website consolidation, disaster recovery, and data center relocation

Data Migration, Wikipedia

In last few years we also have new type of migration – called cloud migration.

WHAT is the migration solution in azure?

There are many different ways you could run your migration projects.
Microsoft Azure provides specialized tools to help you migrate your IT solutions from on-premises and other cloud platforms into Azure. Thus, you could take advantage of  Azure Migrate offers to you..

Azure Migrate provides a centralized hub to assess and migrate on-premises servers, infrastructure, applications, and data to Azure. It provides a range of tools to help you in the migration process. Please, check an official Microsoft documentation on Azure Migrate services here.

What is a Network Infrastructure?

A Network Infrastructure is the physical equipment (also known as, hardware) as well as the software applications that support your company’s services to run. Types of network infrastructure include foundational hardware, software, services and facilities.

The physical network infrastructure requires cabling, routers, switches, and other pieces of equipment which help support them and make sure they are connected internally and externally. However, most Cloud Solution Providers (CSPs) virtualize this physical infrastructure and provide software defined, virtual networks.

What is an Application Architecture ?

An application architecture is a structural map of how an organization’s software applications are assembled and how those applications interact with each other to meet business or user requirements. An application architecture helps ensure that applications are scalable and reliable, and assists enterprises identify gaps in functionality.

The Techtarget

Generally speaking, application architecture defines how applications interact with components such as middleware, databases and other applications. There are many different application architectures like; N-Tier, Web-Queue-Worker, Service-Oriented (SOA), Event-Driven, and others.

Cloud Application Architecture Guide

WHAT are the characteristics of APPlication Architecture in azure?

The Azure Application architecture requires a structured approach while designing applications that are capable to operate with the following characteristics; scalable, resilient and highly available.

The cloud is changing how applications are designed and secured. Instead of monoliths, applications are decomposed into smaller, decentralized services. These services communicate through APIs or by using asynchronous messaging or eventing. Applications scale horizontally, adding new instances as demand requires.

What is the Monitoring ?

The monitoring is a skill and not a full-time job. In today’s world of cloud-based architectures that are implemented through DevOps projects, developers, SREs, and operations staff must collectively define an effective cloud monitoring and logging strategy. This strategy should focus on identifying when service-level objectives (SLOs) and service-level agreements (SLAs) are not being met, likely negatively affecting the user experience.

Cloud monitoring is a method of reviewing, observing, and managing the operational workflow in a cloud-based IT infrastructure. Manual or automated management techniques confirm the availability and performance of websites, servers, applications, and other cloud infrastructure.

Study Guide for AZ-305: Part 1 – Design a Governance Solution

Hello friends,

As you might already know, a new AZ-305 exam for Azure Architects has been officially released a few days ago!!!

I would like to take this opportunity and help all my students and followers with preparation for this important exam.

My plan is to create a blog post series that cover official and community learning materials in addition to the Microsoft Learn, self-paced learning modules.

Table of content (blog series)

This exam is focused on designing cloud and hybrid solutions on Microsoft #Azure, and was made with #architects in mind 😏


A list of helpful reference materials that will complement your four Microsoft Learn AZ-305: XXX learning paths on the official learning site are screenshotted below for your references 🙂

What is the Cloud Governance ?

The Cloud Governance is a framework that guides how end users make use of cloud services by defining and creating policies to control costs, minimize security risks, improve efficiency and accelerate deployment. It’s imperative to have good cloud governance because it’s a foundational element to your cloud practice that provides the ability to scale and be successful.

In short, the governance in Azure is one aspect of Azure Management. This includes the tasks and processes required to maintain your business applications and the resources that support them. Azure has many services and tools that work together to provide complete management. 

What you can do with Azure Governance?

  • Enforce and audit your policies for any Azure service
  • Create compliant environments using Azure Blueprints, including resources, policies, and role-access controls
  • Ensure that you’re compliant with external regulations by using built-in compliance controls
  • Monitor spend and encourage accountability across your entire organization

Welcoming the Microsoft Exam Simulator ✔️

Hi Cloud Marathoners!

It is pretty common for every new student to be worried about exam software ⚙️ and its user expereince, in addition to being prepared for the exam. However, this is not an issue anymore.

Microsoft Learn has introduced a demo exam simulator that looks, works and feels like you are having a real Microsoft exam. This news was just announced by Microsoft Learn Blog.

I believe this is an important help for all the #cloudmarathoners and friends who are just starting their Microsoft Azure journey.

Why is it helpful?

Well, using this new exam sandbox should better prepare you for the exam experience. This should also increase your familiarity with the user interface, how to navigate between exam sections, pages and Q&A.

This simulator also shows you what actions are required to answer each of the different question types, where information about the exam is located, how to mark questions for review and how to provide comments at the end of the exam.

Important

Keep in mind that a secure browser that will be launched during a real exam will block all third-party applications running on your computer. Thus, I would strongly advise you to install and run the exam provider’s (like, Pearson VUE or any other) simulator on your local computer a day or two before the actual exam date. This will be an additional peace of mind to have in your checklist for a pleasant exam experience.

Conclusion

I sincerely wish you Good Luck ❤️ in your upcoming exam(s) !

Azure Bicep First Look course is released!

Happy Friday friends,

Are you looking for a simpler, more efficient way to author infrastructure resources in Azure?

Azure Bicep First Look course


If so, you’re in luck. Azure Bicep is here to help. Bicep is a new domain-specific language (DSL) for deploying resources in Azure. It’s also a much cleaner, more concise language than ARM JSON—cloud admins and DevOps professionals, rejoice!

Please, let me know if you need any help with my new Azure Bicep First Look course.

I am here to help you in your Cloud journey!
Stay tuned for more Azure content!

What are the good options to manage sensitive info in Azure Bicep?

Hello Cloud Marathoners,

Every seasoned IT professional knows that sensitive information should not be exposed as a clear text on any code. This is especially true for infrastructure-as-code (aka, IaC) scenarios where passwords and keys are part of the deployment.

One way to stay compliant in accomplishing this goal is the integration of an Azure Key Vault service into your deployment code. This Azure security service is primarily intended to store sensitive information like password, keys, certificates, connections, etc.

In this post, we will look into two different ways how we could integrate Azure Key Vault services in our Azure Bicep code.


Option – 1: Using getSecret() function

Our first option is to delegate this important work to a getSecret() function. This option could be used with an existing Azure Key Vault resource that is declared in your Azure Bicep code.

Let’s look into an example where an existing Azure Key Vault service is referenced to provide administrative password for SQL server deployment.

Deploying Azure SQL instance with Azure Key Vault

This sample Bicep code is using sqldb.bicep file as a module, where parameters; such as sqlServerName and adminLogin are passed through with a secret name of ExamplePassword.

The ExamplePassword secret name should be already set and ready in the referenced Key Vault service above. Here is the view of this secret on Azure portal.

Azure Key Vault with secretes in portal

Let’s have a quick view into the sqldb.bicep file, as it is referenced in the main Bicep file.

sqldb.bicep file

Now, let’s deploy these resources with a secret value from Key Vault resource that has a secret name ExamplePassword.

What happened? I am getting an error on my first deployment execution 🙁

Error on deploying Bicep code with SQL server provisioning

Upon carefully analyzing error, I see the following reason for this error:

At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.”,”details”:[{“code”:”RegionDoesNotAllowProvisioning”,”message”:”Location ‘East US 2’ is not accepting creation of new Windows Azure SQL Database servers at this time.

Azure deployment error

Based on the error message, we change the location to eastus and re-run the script. Now, we got the following positive result in console and portal:

Deployment results in Azure Portal RG

Next, we will attempt to login into a SQL Server instance.
A successful login will look like the following screen:

Successful login into the SQL instance

Important Note:

If you are getting an error during the login then try to check the following steps:

  • adminLogin name is entered correctly
  • your IP address is added to the SQL server firewall rules
  • grab a cup of coffee and check back in 5 minutes

Description of a typical login error into a SQL server instance is provided below. I checked the firewall rules and made a cup of coffee => before getting a successful log-in 🙂

Requires your location IP activation

Option -2: Referencing as a secretName in parameter

The second option is pretty straightforward, if you have already used it on ARM template deployments.

Note: Please check out the following post – Four parameterization options for your Azure Bicep deployments for detailed information on available options.

We just need to reference Azure Key Vault secret like in the following example:

Using a parameter file and referencing the Key Vault secretName will do the trick in extracting the value and provisioning your resource.

Let’s run the bicep file that deploys multiple RGs and an Azure VM that uses VMPassword secret.

Running deployment with Bicep parameter file

A successful deployment provisions following RG with the VM resources:

Next, we should smoke test our deployment by locating the resource group “rg-demo-vm-1116” and using deployment parameters to RDP into Windows server:

Finally, we are able to see that secret and admin user name pair worked as expected

Azure VM deployed using Key Vault secret

Summary

In this post, we looked into two available options that harden our infrastructure code by removing hard-coded sensitive information and replacing it with Azure Key Vault reference. Thus, avoiding any potential leaks of passwords, secrets, etc.

IMHO, first option is better than the later one, because it does not expose subscription id and other small details.

What will be your choice? Please, share on LinkedIn post comments section.

Thank you for your interest my #cloudmarathoner friends!
Please, check other Azure Bicep posts and let me know your feedback.
