When designing a new Azure infrastructure (either green field project or a migration from an existing infrastructure) it is of paramount importance to plan ahead and be proactive. Planning is always almost the 60-70% percent of the work and deployment/execution is the remaining 30-40%.



A solid high level and low level (detailed) design should encompass the physical and logical aspects of the architecture as well as assess whether a hybrid and/or multi-cloud approach should be taken. Also the design must meet the customer's requirements and follow Microsoft Azure best practices in the following areas:



- Functionality (Azure service features and end user/client accessibility of the infrastructure)

- Non-functional aspects, such as security and performance

- Pricing

To properly size and design an Azure infrastructure with the above design aspects in mind, the following tools and procedures should be used throughout the design process, where applicable:



- Existing infrastructure technical assessment questionnaire. This should be addressed to the customer's IT team at the beginning of a project to be filled-in with information covering all aspects of the existing IT infrastructure. This will better identify existing workloads and will cover operational and non-operational aspects and requirements in the existing infrastructure. The following areas should be documented at high level. Some of the below parameters may be optional, depending on the customer’s existing environment. - List of provisioned resources on-premise, in Azure and in other public clouds, organized by resource type and workload type. Sizing  information for each resource must be provided (e.g. x number of container nodes with x compute capacity). The dependencies of each resource to other public cloud or on-premises resources must also be documented.

- General security and network security requirements

- Identity and access management requirements

- Governance, privacy, and compliance requirements. The governance aspect covers all cloud policies and scripting logic which are applied in the existing solution and which may control the operations of each deployed resource (e.g. cloud resource power on/off triggers, minimum/maximum autoscaling limits, etc).

- Minimum SLA and maximum service downtime requirements

- Upon receipt of the technical assessment questionnaire, you should create a high-level design (including an as-is analysis) for mapping the existing resources to Azure equivalent resources in the case of a migration. Based on the Azure high-level design, you should also create Azure cost estimations (using Azure pricing calculator and Azure TCO calculator) for one or more feasible migration scenarios. This will help your customer understand their design options and make a decision as to the final design.

- A low-level design (detailed design) of the new target Azure tenant/subscription to which the migration from existing infrastructure will take place. The detailed design should apply all Microsoft Azure design best practices and tools, including the following (as part of the Microsoft Assessments microsite):- Azure strategic migration assessment and readiness report

- Azure cloud migration checklist

- Azure cloud adoption framework (CAF)

- Azure well-architected framework (WAF) review

- Azure landing zones and Azure blueprints

Acronis Cyber Protect 15 virtual machine backup not working when using shared mode virtual disks vhds

Image
Case When you apply and run an Acronis Cyber Protect backup against a virtual machine which is part of a guest cluster which makes use of virtual disk shared files of type .vhds (VHD Set), you run across the following error. Activity succeeded with warnings. Activity 'Preparing for backup of virtual machine' succeeded with the following warning 'Windows error: (0xC05CFF0A). The requested operation cannot be performed on the virtual disk as it is currently used in shared mode. Or the error may state something along the lines of: "Failed to open virtual disk file '.vhds'. Unknown format of the virtual disk." The same error as above can occur in virtual machine backup of virtual machines which include a .vdhx shared disk. Solution The above error is by design when you are attempting a virtual machine backup to virtual machine which does not have an Acronis backup agent installed, as per https://kb.acronis.com/content/68573 . According to Acronis, as of July 2

How to perform hardware health checks in Windows

Image
Case You need to perform an overall hardware health check in a Windows machine, running either a Windows client or a Windows Server operating system. This article provides guidance on the steps to carry out to perform hardware health checks in Windows. Solution Carry out the steps below. - Thoroughly check all Windows event logs (Application, System, Security) for any warnings or errors which may be related to issues you are experiencing with your Windows machine. - Check the device management mmc console by running devmgmt.msc. Ensure that you choose to show all hidden devices from the View menu. If you notice any exclamation marks next to any device, you will need to re-install its driver from the respective manufacturer to ensure that there afterwards no warnings in the device management console. - Check the health of all your disks , either HDD or SSD. Follow instructions in the following KB article for steps to follow to check your disk health: https://stefanos.cloud/kb/how-to-ch

How to resolve Group Policy error codes 8007071a and 800706ba

Image
Case You are running "Group Policy Update" on an OU inside the Group Policy Management Console in Active Directory but you are receiving RPC errors from your servers or domain-joined workstations, as shown in the example below. After a Group Policy Update, you come across Group Policy error codes 8007071a and 800706ba. This means that the local Windows Firewall is not configured properly to allow Group Policy (GPO) traffic. GPO traffic an be either remote GPO update or remote GP Resultant Set of Policy (RSOP) operations. Solution Option 1 Run gpedit.msc and create a new local group policy object which implements the following policies under Local Computer Policy --> Computer Configuration --> Windows Settings --> Security Settings --> Windows Defender Firewall --> Inbound Rules : The full configuration is shown below. After the above local group policies are configured on each domain server and workstation, you can start applying group policy objects to the dom
