Microsoft Azure, being a constantly evolving, updating and changing environment, makes it difficult to sometimes follow all that happens around it. I will try to condense some of the announcements based on status – generally available, preview or update features.
Be aware that generally available features/updates might incur costs. Anything that is part of a public preview, does not incur any costs, but also does not have Service-Level Agreement (SLA) attached to it.

Scale Azure Firewall SNAT ports with NAT Gateway for large workloads
Encountering source network address translation (SNAT) port exhaustion is a common issue when dealing with large-scale outbound traffic. For each new connection made to the same destination endpoint over the internet, a new SNAT port is utilized. Once all SNAT ports are used up, it results in port exhaustion. Environments that necessitate frequent connections to the same destination, such as accessing a database hosted in a service provider’s data center, are particularly vulnerable to this issue. Customers who want to connect outbound to the internet should not only consider potential risks such as SNAT port exhaustion, but also how to safeguard their outbound traffic.
Azure Firewall is a sophisticated security service designed to safeguard cloud infrastructures from new and evolving cyber threats through network traffic filtering. All outbound internet traffic routed through Azure Firewall is thoroughly examined, fortified, and subjected to source network address translation (SNAT) to mask the original client IP address. To enhance outbound connectivity, Azure Firewall can be expanded by associating multiple public IPs with the service.

6 ways to improve accessibility with Azure AI
Globally, more than one billion people live with disabilities and often confront obstacles in areas such as employment, education, and social inclusion. To tackle these challenges, Microsoft introduced a new five-year initiative in 2021, prioritizing three areas: creating more accessible technology, leveraging this technology to generate job opportunities for individuals with disabilities, and establishing a more inclusive work environment for disabled individuals. The objective is to narrow the disability gap and utilize the unexplored talent pool of disabled people. Digital technology can play a pivotal role in enhancing communication, interaction, and information accessibility for this community.
Microsoft and Azure AI provide various accessibility solutions to assist organizations in developing more inclusive experiences for their users. These solutions encompass speech transcription and captioning, content readers, translation services, voice assistants, facial recognition, and computer vision. These AI-driven tools can facilitate better access and engagement with digital content for individuals with disabilities, be it through speech-to-text transcription, image captioning, or text-to-speech translation.

Automate your attack response with Azure DDoS Protection solution for Microsoft Sentinel
Azure delivers numerous network security products that aid organizations in safeguarding their applications: Azure DDoS Protection, Azure Firewall, and Azure Web Application Firewall (WAF). Customers can deploy and configure each of these services individually to heighten the security stance of their safeguarded environment and application in Azure. While each product offers distinct capabilities to tackle specific attack vectors, the most significant advantage lies in their combined power. These three products provide more extensive protection when used in conjunction. In fact, to combat contemporary attack campaigns, a product suite should be employed, and security signals from one service should be correlated with another to detect and prevent multi-vector attacks.
The latest addition to this portfolio is Azure DDoS Protection Solution for Microsoft Sentinel. It allows customers to identify bad actors from Azure’s DDoS security signals and block possible new attack vectors in other security products, such as Azure Firewall.

Apply Azure storage access tiers to append blobs and page blobs with blob type conversion
Azure Storage offers different access tiers. Access tiers include hot tier, cool tier, and archive tier. Azure Storage access tiers support only block blobs natively. When you need to save cost of storing append blobs or page blobs, you can convert them to block blobs. Blob type conversion along with tiering is now supported by PowerShell, CLI and AzCopy.

Azure Kubernetes Service introduces two pricing tiers: Free and Standard
AKS’s unique Free tier allows you to only pay for the virtual machines, and associated storage and networking resources consumed. It provides the managed Kubernetes control plane for free. This allows you to deploy unlimited free test clusters. The Free tier is recommended for clusters with less than 10 nodes and for experimenting, learning, and simple testing.
The new Standard tier is the recommended pricing option which comes with greater control, scalability and uptime support. Standard tier will also include additional features – support for up to 5000 nodes per cluster and API server autoscaling.

Managed Run Command – Execute PowerShell or shell scripts on Virtual Machines and Scale Sets
The ability to manage VMs by remotely executing scripts has been improved with the updated Managed Run Command feature. Now it’s possible to execute multiple scripts at the same time, manage their progress and persist the execution outputs. Scripts and parameters can be used in ARM templates to automate the deployment. For long running scripts, asynchronous mode is supported to prevent blocking the VM provisioning.
- RunCommand script timeout can be specified to manage the execution timeline.
- Scripts can run under different user accounts (default to system account or root if not specified).
- If the script output streams are expected to be large, external storage location can be specified to write the output directly.
- Its possible to execute multiple scripts at the same time or sequentially if they have a dependency on one another.
