Azure Solutions Architect Expert Renewal

Once again its that time to recertify, 2022 is going to be the year of renewal and recertification!

After holding the Azure Solutions Architect Expert certification since 2018, I noticed that Microsoft have changed the process in which renewal takes place on this and other Azure certifications.

In place of just writing another exam based on the syllabus you have already studied and been tested on, Microsoft have implemented a renewal process focused on studying Microsoft Learn modules and then writing an online assessment annually to regain and renew your certification. This is a really a great approach as it gets you to keep learning constantly as well as forces you to recertify annually to keep current.

This effectively replaces the previous method of recertifying every two years with a recertification exam. This process has been seamlessly implemented and really gets you to focus in on key study areas that you may or may not have had recent experience in. This is a great way to get you to use Microsoft Learn modules to increase your skills, get exposure to new concepts and recertify your existing certification that you have already had to write numerous official exams in order to gain. This online assessment is completed annually in order to keep your certification and automatically extends the expiration date on the certificate based on your existing transcript.

Please take note: Microsoft will send you reminders on a monthly basis from three months before the expiration of the certificate which gives you ample time to study the Learn modules and complete the assessment before expiration. The certification will renew for a year from the expiration date. The online assessment can also be written at any time during the renewal period. You will get multiple attempts to write if you do not pass the first time, but there are some waiting periods between attempts.

I really think that this is a great innovation from Microsoft Azure and think it would be great if other public cloud platforms could also look into implementing a similar renewal process in order to assist students. There is also, of course, the fact that there is no cost involved in this renewal process which is really a game changer for people who have invested so much time and costs in achieving these certifications.

Azure Solutions Architect Expert: Microsoft Learn Modules

The below list of Microsoft Learn modules can be studied prior to the online assessment. Please note: This is not compulsory in order to complete the assessment but they are really good if you are trying to brush up on or have not been exposed to these concepts since writing your last exam. The Learn modules focus in on a few of the Well-Architected Framework pillars: performance efficiency, security, Cost and also focus in on designing monitoring on Azure. Further reading on the Well-Architected Framework: https://docs.microsoft.com/en-us/azure/architecture/framework/

They then move into Azure Site Recovery (ASR) and Azure backups. There are also some practical labs on Azure SQL DB's. Overall, its around six and half hours on Learn modules before going ahead to take your assessment.

  • Design a holistic monitoring strategy on Azure
  • Microsoft Azure Well-Architected Framework - Performance efficiency
  • Microsoft Azure Well-Architected Framework - Security
  • Protect your Azure infrastructure with Azure Site Recovery
  • Protect your virtual machines by using Azure Backup
  • Back up and restore your Azure SQL database
  • Use monitoring and analytics to gain cost insights
  • Analyze your Azure infrastructure by using Azure Monitor logs

Please see the below link to the official Microsoft Learn modules required for study: https://docs.microsoft.com/en-us/learn/certifications/azure-solutions-architect/renew

By using the above link you are also able to check whether you are eligible for renewal. 

Quick tip: Make sure you sign into the above portal using your existing MCP login details. You are also able to add additional Learn profiles within your account if these are separate.

I have found the overall renewal process simple, well implemented and innovative!

Good luck on completing your Azure Solutions Architect renewal in 2022!

AZ-302 Transition into Architecture



I had the opportunity last week to write the new beta Microsoft AZ-302 transition exam for the new role based Azure Solutions Architect qualification being provided by Microsoft on their Azure Cloud Platform. This exam is only available if you have completed the 70-535 exam for Architecting Azure Solutions which I have previously written about.

This is a new exam that was released at the end of September 2018 and is still currently in beta meaning that you do not receive any results immediately after writing this exam. Microsoft confirms that you should receive transcript entry two weeks later if you pass.

As this is a new exam in beta there is currently very limited available study materials. In fact Microsoft have not released any practise tests or courses on this exam as of October 2018.

https://www.microsoft.com/en-us/learning/exam-az-302.aspx

The best pace to start preparing for this exam is by viewing the official exam page listed above. On this page you will find the exam section breakdown on the AZ-302:

Determine Workload Requirements (15-20%)
Design for Identity and Security (5-10%)
Design a Business Continuity Strategy (15-20%)
Implement Workloads and Security (5-10%)
Implement Authentication and Secure Data (5-10%)

Develop for the Cloud (45-50%)

As you can see from the breakdown the last section is Develop for the Cloud (45-50%) this section is very important and something that was not tested at this level in the 70-535. If you do not have extensive Cloud development background its best to start doing so now.

I used the following sources for studying for this exam including hands on labs and practising within an Azure subscription. The best place to find these is in the new Microsoft Learning portal within the Azure website. This is a great place to run through study courses and labs without having to create an Azure trial. Experience and skills are really key here.

https://docs.microsoft.com/en-gb/learn/azure

I also used the following free resource on Microsoft Azure courses which is great!

The Microsft Azure documentation is another great place to read up and study, here are some sample links to read that are related to this exam and that I read before writing:

https://docs.microsoft.com/en-us/azure/active-directory/develop/v1-protocols-openid-connect-code
https://docs.microsoft.com/en-us/azure/active-directory/develop/v1-protocols-oauth-code
https://docs.microsoft.com/en-us/azure/site-recovery/vmware-azure-set-up-replication

https://docs.microsoft.com/en-us/azure/azure-functions/durable-functions-overview

https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-transactions-overview 

I would go through all the documentation related to the exam sections above and constantly keep reading through the relevant documentation on the study section that you are focusing on as this gives you some good perspective and a high level understanding on solutions.

To sum up the above resources are a good place to start for this exam but this exam is not  at all easy especially if you don't have strong cloud development background. Developing for the Cloud would be a great place to start learning or brushing up before tackling this exam. The key take away is that you really need strong Azure experience and high level understanding. This is not a standard architect level exam and will really take you into a technical deep dive so practise, skills and deep knowledge are really important.

Lets talk about managed disks


What are Azure managed disks? Why are these the best practise to roll out on new virtual machine builds? What are the advantages of using managed disks? Today we will be discussing these questions in more detail and providing useful information about managed disks.

Managed disks are Azure managed virtual machine disks that are easily added during virtual machine (VM) builds. When activating the managed disk its added to your VM in replacement of the traditional storage account based unmanaged disk. Originally this was the only way of doing this as all VM disks had to be placed into storage accounts. Adding a managed disk though VM creation is a very easy process and literally takes one click:


There are many advantages for using manged disks opposed to traditional unmanaged disk storage which are mainly related to less overhead management, less resource sprawl, secured disk storage, better high availability and reliability on virtual machine disk storage.

Simplified Management - You can specify the type of disk and size needed and Azure will automatically create and manage the disks for you.

Scalable virtual machine deployments - Create thousands of managed disks within minutes. Create up to 1000 virtual machines in scale sets in a single large cluster.

More Secure - Using Azure RBAC (Role Based Access Control) you are able to create granular role based access control on your managed disks.

Highly durable and available - Your data is replicated simultaneously to three different replicas. If one replica fails there are two others to take over.

The below is a great comparison between unmanaged and managed disks:


There are also various further advantages of using managed disks. Namely multiple storage options like SSD premium managed disks for critical performance intensive workloads, and HDD for standard managed disk non-critical workloads. Easy migration from standard to premium managed disks as well as your existing ARM (Azure Resource Manager) virtual machines into managed disks. Point in time backup snapshot of your managed disk to create new managed disks later. Simple custom image management and encryption with bringing your own keys is available.

Managed disks are now the best way to use virtual machine disks in Azure. It's actually much easier to roll out and less admin than unmanaged disks as well as more reliable.

What exactly is Cloud Storage?



This is a really good question for anybody starting to think about the Cloud and starting their journey towards migrating their workloads. It seems like a very simple question but sometimes the answer is not as simple as may be expected. Cloud storage is the key aspect in cloud migration as this is where and how all of your data will be stored.

A good way to explain cloud storage is by comparing consumer vs commercial cloud storage. Most people these days are actively using and relying on cloud storage everyday through One Drive, Google Drive, Dropbox and the large number of other providers. Basically all these options are the same, store your media, images, files offsite in the cloud.



The commercial aspects of cloud storage are a bit more complex as you will need to identify your workload and requirements of it. As in blob storage is great for videos, images and media but that will not work with databases or application back end data. The various cloud suppliers have various tiers of cloud storage to help you identify your requirements. These can range from "hot" storage or frequently accessed data to "cold storage" archive data.

Looking at the Microsoft Azure offerings the below different products are available:

File
Simple, distributed, cross-platform file system

- Lift and shift migration
- Simple and inexpensive
- Move data to cloud with no coding

Disk
Premium storage for I/O-intensive applications

- Low latency, high throughput
- Automatic triple replication
- Enterprise-grade durability
- Learn more

Blob
Massively-scalable object storage for unstructured data

- Cost-effective for massive volume
- Tiered storage options
- Single infrastructure with global reach
- Learn more

Queue
Durable queues for large-volume cloud services

- Simple, cost-effective messaging
- Decoupled component flexibility
- Resilient scaling and buffering
- Learn more

Table
- Flexible NoSQL database

Key-value table storage
- Structured or unstructured data
- Low latency at Internet scale
- Learn more

Archive
Low cost storage for rarely used data

- Data automatically encrypted at rest
- Seamless integration with hot and cool storage tiers
- Supported by leading Data Management partners

Most cloud providers fit into the same above categories with different service offerings and names, Google Cloud Platform for instance offers the following in Google Cloud Storage:


Please see bottom of the article for links with further details and information.

A good way to start with cloud storage options are with your backup or archival data. By moving this data to the cloud a company can start leveraging the power of cloud without initially moving their entire workload. By storing your backups and even running your daily, weekly or monthly backup runs into the cloud this will provide a cost effective and reliable offsite backup option that can really prove to be invaluable in the case of a disaster.

There are really a huge volume of different cloud backup providers these days which all basically offer the same thing with different types of software. Locally running backups that copy your data to the cloud. All of these products will use either their own cloud storage servers or more likely one of the big cloud providers. You might even be able to get the choice of which public cloud storage provider you use with the specific backup product. You could also go directly to a public cloud provider and use their native cloud backup tools.



There are also on premises to cloud replication devices such as Microsoft's Storesimple that will automatically move your archival or "cold' on premises data into the cloud. This is something that can assist with large enterprise storage volumes and cloud storage adoption.

Ultimately cloud storage is expanding rapidly with the great volumes of data being generated everyday and it is really the future of all data storage. Going forward it will be easier, safer and more cost effective to utilise and migrate your current on-premises storage into the cloud. A good way to start on this journey is with your backups.
