Authenticating with s5cmd

Published 2022-02-25 by Kevin Feasel

Anthony Nocentino has the need for speed. And authentication:

At work, I get to work with some fantastic tech that pushes the boundaries of performance. I needed to do some performance testing from a Windows server into a FlashBlade using s3. I reached out to a colleague of mine, Joshua Robinson, who told me about s5cmd. s5cmd is a very fast, parallel s3 compatible command-line client.

Check out Joshua’s post for some performance numbers. Here’s a direct quote from his post.

But it doesn’t matter how fast it is if you can’t connect, so Anthony shows us how to do just that.

Deploying SQL Scripts via Azure Release Pipelines

Published 2022-02-24 by Kevin Feasel

Meagan Longoria solves a problem:

We chose release pipelines over the YAML pipelines because it was easier to manage for the client and pretty quick to set up. While I had done this before, I had a couple of new challenges:

– I was deploying to an Azure SQL managed instance that had no public endpoint.

– There were multiple databases for which there may or may not be a change script to execute in each release.

This took a bit longer than I expected, and I enlisted my coworker Bill to help me work through the final details.

Read on to see how Meagan and Bill solved the problem.

Mission-Critical Azure Architectures

Published 2022-02-23 by Kevin Feasel

Ben Brauer has some reference guidelines:

The AlwaysOn project strives to address the challenges of building mission-critical applications by providing organizations with a prescriptive architectural approach for the Microsoft Cloud.

It leverages lessons from numerous customer applications and first-party solutions, and applies Well-Architected best practices to provide actionable and authoritative guidance for building and operating a highly reliable solutions on Azure at-scale.

I guess marketing is calling it “AlwaysOn” again. Until they call it Always On. Or AlWaYsOn.

Methods to Export Azure SQL Database

Published 2022-02-22 by Kevin Feasel

Abhishek Shaha and Ahmed Mahmoud enumerate techniques to export an Azure SQL Database:

Export Azure SQL Database is a common request for Azure SQL DB customers, in this article we are going to list down some advanced scenarios, on how this can be achievable through various tools not limited to Azure Portal, Azure CLI and PowerShell. In addition, this article will provide alternative methods when it comes to private endpoints and deny public access.

What Comes after the Well-Architected Framework Review

Published 2022-02-18 by Kevin Feasel

Ben Brauer takes us through the next step:

Congratulations! You’ve finished your Well-Architected Review of a workload, giving you a better understanding of where it could be fortified along the five pillars: Security, Reliability, Operational Excellence, Performance Efficiency and Cost Optimization. You have received Microsoft’s best practices as recommendations based on your answers to questions specific to each pillar.

The report (example below) shows a Well-Architected score for each pillar, as well as prioritized recommendations that allows for you to focus on biggest areas of impact. A great example is virtual machine right sizing. You can significantly lower your costs if you know which VM is best suited for your workload type.

By the way, if you have Azure resources, I highly recommend checking out the Well-Architected Framework assessment link there. It can take a very long time to go through because of just how many questions there are; that said, the results are also pretty specific and can be immediately helpful.

Amazon RDS: Backups and Patching

Published 2022-02-18 by Kevin Feasel

Joey D’Antoni is not impressed:

While some services include other really useful features (for example the query data collected by the Azure SQL Database and Managed Instance platforms), I wanted to focus on the common value adds to PaaS systems across providers. I made the last two of these bold, because I feel like they are are the most important, especially in scenarios where the vendor doesn’t own the source to the applications. Like Amazon RDS for SQL Server.

Creating an Azure Integration Runtime

Published 2022-02-17 by Kevin Feasel

Andy Leonard builds out an Azure Integration Runtime:

Many Azure Data Factory developers recommend creating an Azure Integration Runtime for use with Mapping Data Flows. Why? One reason is you cannot configure all the options in the default AutoResolveIntegrationRuntime supplied when an Azure Data Factory instance is provisioned.

At the time of this writing, it’s not obvious how one creates an Azure Integration Runtime. You would think creating an integration runtime would begin with:

It turns out to be a little trickier than you might first expect.

Replication in Azure DB for MySQL

Published 2022-02-16 by Kevin Feasel

Arun Sirpal explains how you can set up replication with Azure DB for MySQL:

No doubt there will be a need for you to split off your analytical queries from the main database for performance reasons.

If you have been following me in the past with Azure SQL DB you would use failover group read endpoints. With MySQL we would need to build a replica (read only) to another server. This uses MySQL’s native feature binlog replication which is great to hear. This form is asynchronous.

Finding Public IP Addresses in Azure

Published 2022-02-15 by Kevin Feasel

Werner Rall is looking for public IPs:

Creating Resources in Azure is so simple for IT teams these days but finding all the public endpoints that could be visible to the internet can be challenging. Why do I need to understand which IP’s are exposed to the internet? Without a proper understanding of which Public IPs are available to the internet we cannot fully secure or protect our resources. In this article we will look at using the Azure Native Graph Explorer solution to query not only Virtual Machine Public IP Addresses but other resources containing IP addresses in our Azure Tenant.
