Cloud Repatriation: Is it a Risk For Microsoft Azure? | Petri (Petri.com)

Cloud repatriation appears to be one of the new IT hot topics of 2023. For companies that invested time and money into transferring some of their workloads ...

[Windows Server](https://petri.com/category/windows-server/)? When is the last time you heard of a [Windows Server 2022](https://petri.com/install-windows-server-2022/) training course from Microsoft? [operational expenditure](https://en.wikipedia.org/wiki/Operating_expense) (or OPEX): You use something and a cost is accrued. [approximately 12-hour outage](https://www.datacenterdynamics.com/en/news/data-center-power-surge-and-cooling-failure-brings-down-microsoft-azure-services/) because of a large-scale cooling issue. The difference is that companies like Microsoft pay a lot of money to have really good people fix the issues when they eventually happen. If an organization is struggling to get value from the cloud and the costs are increased, then questions about reversing course must be expected. I explained why in my previous [5 Essentials for Successful Cloud Adoption article](https://petri.com/cloud-adoption-essentials/). One of my talking points for 2022 (and 2023) is that organizations have not used a good process to get into the cloud. The cost of cloud platforms like Azure is very different from traditional IT environments. As for routing, well, Azure’s version of shutter speed/aperture/ISO (photography terminology) controls all aspects of Azure networking and network security in ways that you must be able to figure out with almost no tooling and rarely available diagnostics data. I wrongly assumed, at first, that it was about moving services and data to a more local instance of the cloud. Cloud repatriation appears to be one of the new IT hot topics of 2023.

Automate your attack response with Azure DDoS Protection solution ... (Microsoft)

We created the new Azure DDoS Protection solution for Microsoft Sentinel that helps organizations to protect their resources and applications better against ...

When Azure DDoS Protection service detects the volumetric smokescreen attack, it starts mitigating it, and signals logs to Sentinel. It uses Azure DDoS Protection and Azure WAF to protect its web application. We will continue to enhance this solution and add more security services and use cases. Azure DDoS Protection detects the smokescreen attack and mitigates this volumetric network flood. - A Remediation IP Playbook that automatically creates remediation in Azure Firewall to block the source DDoS attackers. These rules will prevent any non-DDoS attack from reaching the resources in the virtual network, even after the DDoS attacks ends, and DDoS mitigation ceases. They then plan to access the network resources by scanning and phishing attempts until they’re able to gain access to sensitive data. This cross-product detection and remediation magnifies the security posture of the organization, where Sentinel is the orchestrator. 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. Our new Azure DDoS Protection Solution for Sentinel provides a single consumable solution package that allows customers to achieve this level of automated detection and remediation. One of the most devastating features of DDoS attacks is their unique ability to disrupt and create chaos in targeted organizations or systems. Each of Azure’s network security services is fully integrated with Microsoft Sentinel, a cloud-native security information and event management (SIEM) solution.
