With the shift in the computing paradigm to the cloud, the Azure ecosystem is quickly becoming a critical platform for IT pros to grasp and adopt. But how do you make the leap while maintaining security, manageability, and cost-control?
Whether you’re making new VMs directly in the cloud, have VMs in your own datacenter and are looking to migrate to Azure, or you’re looking to manage VMs with cloud-based tools regardless of where they live, The SysAdmin Guide to Azure Infrastructure as a Service (Iaas) will teach you to set up and maintain a high-performing Azure IaaS environment.
Written by veteran IT consultant and trainer Paul Schnackenburg, Altaro’s free 100+ page second edition eBook covers how to create VMs, size them correctly, and manage storage, networking, and security, along with backup. You’ll also learn how to operate groups of VMs, deploy resources based on templates, manage security, and automate your infrastructure. There are also two new chapters on Automanage and Azure Arc to help you bring a lot of automation to IaaS, all lessening the burden on your time.
One thing that has changed significantly over the past couple of years is the shift towards making IaaS VMs more like PaaS services. VMs are great but they require a lot of maintenance and care, whereas all the business is really interested in are the applications and data that run inside of them. This explains the popularity of PaaS services such as managed Kubernetes (AKS) and Azure Functions (serverless).
If you’re new to the cloud (or have experience with Amazon Web Services and/or Google Cloud Platform but not Azure) this eBook will cover the basics as well as advanced skills. And given how fast things change in the cloud, it covers the why (as well as the how) so that as features and interfaces are updated, you’ll know how to proceed.
AZ-103 is one of the newest exam that became available for taking about one month ago. It’s also one of the few exams that have been updated with real labs sections (or performance testing). What does it mean? The exam starts with usual questions, then goes labs where you have to complete tasks by using Azure Portal and Azure Cloud Shell inside of the exam’s subscription. I had about 15 lab tasks, 2 different lab sections with 6 and 9 tasks perspectively, and case studies after each of the labs. In short, it is a real brainstorm – when you think the exam ends, the next questions or labs appear out.
Honestly, it was the hardest exam I have ever had and took me almost 3 hours to get it finished (my personal record, by the way). Again, even though I passed on the first try, it was difficult! Why? I’d say time management is the big challenge, so be well prepared and expect some gotchas. Anyway, I’m extremely happy to see real labs in the exams as they can filter “dumpers” out and make certification more valuable to all of us.
How to prepare?
Azure Subscription (trial at least)
You must have a real experience in the commercial projects (mid-sized and higher). For example, I have been working with Azure for 3 years so far and now work with different projects related to Azure and DevOps.
Use free online resources for preparation. Please check my post in order to get the list of all available high-quality and free training courses . I used Pluralsight (more than 40 hours), Udemy (AZ-300 paid course), Azure DevOps Labs, hands-on labs, official docs and study guides (MCT). So, I’ve being preparing for 2 months.
Read about performance testing (sections with lab tasks). Some notes: time has been already extended to 180 mins for exams with performance testing, az-103 includes performance testing, choose Bash at the first launch of Azure Cloud Shell, and then switch to PowerShell, otherwise, storage for Cloud Shell won’t be created (just my experience) + add new resources on the resource group level rather than adding them from the main page using search bar or “Create Resource” on the left sidebar (faced with issue that I couldn’t get subscription/RGs list during resource creation, so I navigated to pre-created RG and completed all lab tasks from there)
If you pass the exam successfully, the certification will be valid only for 2 years, so keep learning and practice every day! I wish you good luck on the exam and may the force be with you 🙂
