Azure Site Recovery Usage Scenarios

Usage Scenarios for Azure Site Recovery - paraphrased from various online articles:

* Disaster recovery in the cloud—You can replicate workloads running on running on supported on-premises Hyper-V VMs, VMware VMs, and physical servers to Azure, rather than to a secondary site. This eliminates the cost and complexity of maintaining a secondary datacenter. ASR provides orchestrated disaster recovery as a service (DRaaS). When failover occurs, Azure VMs are created based on the replicated data. You can run planned failovers for expected outages with zero-data loss, or unplanned failovers with minimal data loss (depending on replication frequency) for unexpected disasters. You can easily fail back to your primary site when it's available again. Advanced network management in Site Recovery and Azure simplifies application network requirements, including reserving IP addresses, configuring load-balancers, and integrating Azure Traffic Manager for efficient network switchovers.

* Migrate on-premises AWS instances to Azure VMs, or to migrate Azure VMs between Azure regions.

* Testing without disruption - You can easily run test failovers to support disaster recovery drills, without affecting production environments.

* No-impact recovery plan testing - Recovery plans allow you to model and customize failover and recovery of multi-tier applications that are spread over multiple VMs. You order groups within plans, and add scripts and manual actions. Recovery plans can be integrated with Azure automation runbooks.

* Protect the SQL Server back end of an application using a combination of SQL Server business continuity and disaster recovery (BCDR) technologies, and Azure Site Recovery.

Maven Crash Course - Learn Power Query, Power Pivot & DAX in 15 Minutes

Image
In the Maven Crash Course " Learn Power Query, Power Pivot & DAX in 15 Minutes ", Chris Dutton walks through a hypothetical business case while showcasing the power of modern Excel tools like Power Query, Power Pivot and DAX. Power Query is used to extract, transform, and load data from external sources like SQL databases, PDF and CSV files. A relational model is created to join the tables without writing a single formula. Exploratory analysis is done using Power Pivot and Data Analysis Expressions (DAX). Data Analysis Expressions is the language that we can use to define new calculated columns and measures to enhance our Data Model instead of the traditional cell formulas that we'd typically use if our data was stored in worksheets. Pivot Charts and slicers are used to design a simple interactive report that the sales managers can use to analyze revenue trends and product performance.

Oracle Cloud Infrastructure 2024 Generative AI Professional Course & Certification Exam (1Z0-1127-24)

Image
I was happy to learn about the Oracle Cloud Infrastructure 2024 Generative AI Professional Course with video tutorials and the Certification Exam (1Z0-1127-24) from their newsletter. I found it extremely useful, timely, and relevant. The course, with about 6 hours of videos, provided me with a comprehensive view of what it takes to build a Generative AI application. Although some parts reference OCI services, much of the course remains vendor neutral. Rohit Rahi and his team at Oracle have done a great job of structuring the beginner-friendly yet comprehensive course so well, covering all the essentials across four modules. The curriculum strikes an excellent balance between depth and accessibility.  While Gen AI output is typically non-deterministic, I was surprised to learn that they can be made completely deterministic under certain conditions. Specifically, in the OCI Gen AI service, setting the temperature parameter to 0 produces consistent, deterministic output for a g...
