In Azure, every VM has a persistent OS Disk that is used for booting the VM and contains the operating system. In addition to an OS disk, each VM also has a temporary disk that is present on the compute cluster hosting your VM. Why is my OS disk not @ /dev/sda? In most cases the OS disk is /dev/sda but in some odd cases it is not. This is not an Azure specific issue but a default Linux behavior....
When you need to create a lot of instances from a custom VM image, VM Scale Sets and Shared Image Gallery are the services you need to use. In this session we walk through how to combine the power of VM Scale Sets & Shared Image Gallery to build infrastructure at scale.
Managed Disks make the managedment of disks a breeze in Azure. In this session I talk about the updates we’ve introduced to Managed Disks since Ignite 2017.
Azure Resource Manager stack has been released for almost three years now. In those three years many features have been added that are exclusive to Azure Resource Manager. In this session, I demonstrate the process of migrating your existing infrastructure to Azure Resource Manager without downtime. See a list of all the benefits here: https://azure.microsoft.com/en-us/blog/migrate-iaas-to-azure-resource-manager.
Sharing custom images within an organization to different subscriptions globally has been a long standing ask from Azure customers. With Shared Image Gallery we’re making this dream a reality! Read more about Shared Image Gallery https://azure.microsoft.com/en-us/blog/shared-image-gallery-now-in-limited-public-preview/ In this session, I present how customers can get started with Shared Image Gallery.
In the world of cloud, horizontal scaling is well understood these days. It is easy to use applications like Kubernetes to automate the scale out your containerized applications based on workload demand. For applications running on VMs, we have cloud native services like VM Scale Sets that make scaling in and out a breeze. However, for an on-prem application going through a lift & shift to the cloud, vertical scaling of the VM is still the king....
Azure recently introduced its first burstable VM size - the B-series. This VM type is meant to compete directly with AWS' T2 instances. In the below few words (or more :smile: ) I try to explain what this means and why you should care. If you still have questions after reading, hit me up on Twitter or leave a comment below. So why do I need a burstable size anyway? If you have applications that remain idle for a long time and burst occasionally, then the B-series might be the perfect fit for you....
