Unplanned Outage?
Hi Lab Services team, Are there any updates I can share with my affected users? Students have assignments due tomorrow (Monday 13/05, Australia East) and I'm having to tell the subject coordinators that they won't be able to hand them in. What are your current theories about the cause or estimates for a timeline?
Cannot start VMs, template, or create a new lab
We are currently seeing an issue where we cannot start our VMs, we just see this message: "Virtual machine redeploy operation failed. Try redeploying the virtual machine. If the issue persists, consider reimaging it. For further assistance submit a support request." Redeploying does not make any difference, and we are reluctant to reimage as MS have acknowledged a bug whereby the SSD of the VM can shrink after a reimage: in any case we also cannot start our template. We cannot make a new lab: when we try we see the "gorilla holding a sign" indication that something has gone wrong on both the dashboard and template pages for that lab. Our lab plan is based in UK South. We are unable to create an alternative lab plan in another region as the portal says we are not allowed to due the retirement of ALS in 2027! Has anybody seen similar and has any suggestions?
Disk throughput performance differences between template and pool VM
Hi, While testing a Lab I'm preparing, I noticed that the disk throughput performance of my template was as much as 5 times faster compared to a pooled VM from that very same template. I'm using the "Large VM (nested virtualization)" template with the "128 GB Premium SSD" option. The template itself reaches about 150 Mbyte/s, while the pool VM maxed out at 30 MByte/s. The VM is running Ubuntu 22.04 LTS. I'm testing as follows: dd if=somebigVMfile.vdi of=/dev/null bs=1M status=progress Is there something wrong with the pool VM? Anything it can/should/must do to change this? 30 Mbyte/s is way too slow for a "premium SSD". Thank you!Azure Fundamentals Demystified: Unveiling the Architecture and Services of Microsoft Azure
Hi everyone! I'm Mohammed Elshahat Ismail, a 21-year-old from Egypt :egypt: with experience in various roles such as Microsoft Certified Trainer, https://gdsc.community.dev/u/mbvdbj/#/about, NASA Space Apps Local Lead and Founder in Damietta, https://studentambassadors.microsoft.com/en-US/studentambassadors/profile/eecd1e4b-b456-421f-aeb4-76fbe98ba39e, and Hult Prize Campus Director and Founder. Today, I'm excited to dive into the world of Azure Fundamentals and explore the fascinating architecture and services offered by Microsoft Azure. The Microsoft Azure Fundamentals training comprises three learning paths, and in this article, we will focus on the second path: Microsoft Azure Fundamentals: Azure architecture and services. This learning path provides valuable insights into the architecture of Microsoft Azure and introduces some of the most commonly used services and resources within the platform. Azure, Microsoft's cloud computing platform, offers a vast range of services that enable organizations to build, deploy, and manage applications and services with ease. Understanding the underlying architecture and the various services available is essential for anyone looking to harness the power of Azure. Azure's architecture is built upon a global network of data centers managed by Microsoft. These data centers are strategically distributed worldwide, allowing users to deploy their applications and access their services with low latency and high availability. Azure's architecture follows a scalable and distributed model, ensuring resilience and redundancy across its infrastructure. Within Azure, resources are organized into regions, which are geographic areas containing multiple data centers. Each region is independent and comprises one or more availability zones. Availability zones are physically separate data centers within a region, providing fault tolerance and high availability. By deploying resources across availability zones, organizations can ensure their applications remain accessible even in the event of infrastructure failures. Now, let's explore some of the key services offered by Azure. Azure provides a comprehensive suite of services that cater to diverse business needs. These services can be categorized into compute, storage, networking, and databases. Compute services in Azure include virtual machines (VMs), which offer the flexibility to run various operating systems and applications in the cloud. Azure also provides container services for efficient application deployment and management, as well as serverless computing options that abstract away infrastructure management, allowing developers to focus solely on code execution. Azure's storage services offer scalable and secure storage solutions to meet different storage requirements. Azure Storage provides options such as Blob storage for unstructured data, File storage for file shares, and Queue and Table storage for messaging and NoSQL data storage, respectively. Additionally, Azure Disk Storage offers persistent and high-performance block storage for virtual machines. Networking services in Azure empower organizations to build secure and scalable architectures. Azure Virtual Network enables the creation of isolated networks and facilitates connectivity between resources. Azure Load Balancer and Azure Application Gateway distribute incoming network traffic to improve application performance and availability. Azure VPN Gateway allows secure connectivity between on-premises networks and Azure. Azure's database services cater to various data management needs. Azure SQL Database offers a fully managed, scalable, and secure relational database service. Azure Cosmos DB provides globally distributed, multi-model database capabilities. Azure also offers fully managed open-source database services for MySQL, PostgreSQL, and MariaDB. Additionally, Azure Redis Cache enables high-performance caching, while Azure Synapse Analytics offers powerful analytics and data integration capabilities. In conclusion, understanding Azure architecture and the wide array of services it provides is crucial for anyone venturing into the realm of Microsoft Azure. The Azure Fundamentals: Azure architecture and services learning path offers a valuable opportunity to explore the core concepts, architecture, and commonly used services within Azure. With this knowledge, individuals can leverage Azure's capabilities effectively and embark on a journey of innovation and digital transformation. So, let's dive into the exciting world of Azure architecture and services together! Happy learning and exploring Azure Fundamentals! Best regards, Mohammed Elshahat Ismail
