Considerations on using Load Balancing with Azure VMs

During this week, I had to design a solution using Azure Load Balance to build, to host a significant amount of content that requires a lot of bandwidth. From what I could find, the size and the series of the VMs in Azure impacts on the output of the bandwidth, and directly impacts on the performance of the solution. So, after careful calculation we decide to go with the F-Series....

Choosing the type of Azure Blob storage for SQL Backups

During the storage design on the Azure Foundation workshop that I usually deliver on a beginning of a new Azure project, come the topic and following that, the discussion about what type of storage should we choose for the SQL Backups. After reviewing the different offerings that Azure provide for storage, we start to brainstorm. Assuming that we are using blob storage for SQL Backups on a running SQL on...

Understanding the limits on Azure Key Vault

When you are designing the architecture for your application on Azure, I always revisit the Azure Subscription Service Limits to see if all the requirements are not over the Azure Limits. Although, this time after evaluating and discussing with the team the Key Vault Limits, to be more precise the number key transactions that application is allowing to use regarding each type of key, I have to say that was...

Load Balanced and Availability Set with multiple VMs

When it comes to best practices to how to setup multiple virtual machines using a load balanced and availability set, the information out there is either outdated or hard to find. What is the scenario? Imagine that you need to set a few VMs that need to be shared the configuration and some files between them. How you could do it? After a few searches on the web, I come...

Creating a Point-to-Site VPN on Azure

To understand deeper what are the options you have to connect your organization with Azure, I recommend read this older post. On this post, I want to share what do you need to configure so you can implement a Point-to-Site (P2S) VPN between your organization individual PC and your Azure environment. This is the typical process for creating and configuring a virtual network with point-to-site connectivity: Create the root and client...

Options to connect your datacenter to Azure Virtual Networks – Part 4 – ExpressRoute

On the one of the previous post (see here) I briefly describe the options that you have to cross-premise connections to Azure. On this post, I want to explore more one of the options: ExpressRoute. ExpressRoute delivers private, network-layer connectivity between on-premises networks and Microsoft Cloud, without crossing the Internet, in the form of: Private peering. This includes connections to Azure virtual machines and Azure cloud services residing on Azure virtual...

Options to connect your datacenter to Azure Virtual Networks – Part 3 – Site-to-Site VPN

On the one of the previous post (see here) I briefly describe the options that you have to cross-premise connections to Azure. On this post, I want to explore more one of the options: Site-to-Site VPN. Site-to-site VPNs rely on static routes to direct traffic between on-premises networks and Azure virtual networks. The Azure platform generates these routes when you create the site-to-site VPN connection based on two pieces of data:...

Containers on Azure – Part 1

In the last decade, hardware virtualization has drastically changed the IT landscape. One of many consequences of this trend is the emergence of cloud computing. However, a more recent virtualization approach promises to bring even more significant changes to the way you develop, deploy, and manage compute workloads. This approach is based on the concept of containers. These series of posts explain containers and the ways you can implement them...

Virtual Machine Scalability in Azure – Part 1

You can provide automatic scalability for Azure VMs by using Azure VM scale sets. A VM scale set consists of a group of automatically provisioned Windows or Linux virtual machines that share identical configuration and deliver the same functionality to support a service or application. With a VM scale set, the number of virtual machines can increase or decrease, adjusting dynamically to changes in demand for its workload. The workload...

How to use Blob containers in Azure

I know that Microsoft Azure looks easy, because you create your subscription, then you start to consume all the resources. But in some cases, start to be overwhelming, with so many details that you must take in consideration, it’s not easy to take advantage of what Azure have to offer you. Regarding the Azure storage, sounds easy but, in a lot of cases I’m seeing some implementations that are not...
