This Week I Learned - Week #7 2019
This Week I Learned -
* You can use Azure Site Recovery to move your single instance VM or VMs in an Availability Set into an Availability Zone, thereby achieving 99.99 percent uptime SLA.
* Azure continuously monitors for hardware that shows signs of degradation or potential failure. When these conditions are detected, Azure will attempt to live migrate your virtual machines (VMs). If live migration isn’t possible, Azure will automatically redeploy VMs to a healthy machine.
* There are cases where live migration isn’t possible, like on specialized computer hardware such as M-Series, G-Series, etc. or on legacy hardware, in which case the VMs would be redeployed to a new instance.
* When Azure detects imminent hardware failure, VMs are proactively live migrated when possible. This should have minimal impact on your workloads and the customer experience is typically a freeze of a few seconds during the final phase. Subscribing to Scheduled Events allows your VM to be notified a few minutes before the live migration process is started.
* Scheduled Events will now be triggered when Azure predicts that hardware issues will require a redeployment to healthy hardware in the near future, and provide a time window when Azure will redeploy the VMs to healthy hardware if a live migration was not possible. Customers can initiate the redeployment of their VMs ahead of Azure automatically doing it
* Azure has taken insight from operating millions of servers in its data centers to identify when hardware health is degrading and predict in many cases a failure before it happens - Azure Blog
* Scheduled Events is an Azure Metadata Service that gives your application time to prepare for virtual machine maintenance. It provides information about upcoming maintenance events (e.g. reboot) so your application can prepare for them and limit disruption. It is available for all Azure Virtual Machine types including PaaS and IaaS on both Windows and Linux.
* The Azure LSV2 VM series is well suited for your high throughput and high IOPS workloads including big data applications, SQL and NoSQL databases, data warehousing, and large transactional databases. Examples include Cassandra, MongoDB, Cloudera, and Redis. In general, applications that can benefit from large in-memory databases are a good fit for these VMs.
* Azure customers can replicate and failover zone pinned virtual machines to other regions within a geographic cluster using ASR.
* Azure Cognitive Services today includes 14 generally available products.
* Spear phishing tries to make an email look like its coming from someone known to the victim, by modifying the displayed sender name so that it is more recognizable to the recipient
* Kintsugi literally translated means “golden repair.” But it’s much more than that. Kintsugi is a philosophy of repairing broken things, like cracks in pottery, for example. Rather than hide an item’s imperfections, the reparation process highlights them. Those imperfections are considered part of an item’s history, and repairing it this way can add beauty to the original items — like using precious metal to fix cracks in pottery.
* The T. & A. Baťa Shoe Company was founded on 24 August 1894 by Czech entrepreneur Tomáš Baťa. The company has a retail presence of over 5,300 shops in more than 70 countries and production facilities in 18 countries - Wikipedia
