A post close to my heart, Azure SQL Managed Instance, I have blogged about this many times but I feel I should be sharing more details about this. One important topic – Maintenance windows.

Azure Redis Cache and Geo-replication
The concept of a geo-replicated partnership between a primary and secondary node is very similar to that of something you may have seen with Azure SQL DB, where the primary handles all R/W and then the changes are pushed to secondary ( async). This is no different with Redis.
Azure Redis Cache – scaling
Let’s assume that you started off with the lower editions and capacity with Redis and your developers tell you to scale the Redis cluster. Well first to use a cluster you need premium. Below under the cluster size option in the Azure portal you will see the message:
Tips for Azure Redis Cache
My learnings on Redis thus far which you may find useful:
Azure Redis Commands
Now that we have created our Redis Cache lets connect to it. You can use the most common tool redis cli.exe https://redis.io/download or as I am going to do, use the Azure Portal to use the console directly, this isn’t probably the best way but it’s the easiest for this blog. 2 key points here:
Building Azure Redis Cache
Let’s go through a Redis build process. It will be fun.
Azure Redis Cache Intro
Redis Cache is a well know caching technology and you can run it in Azure as a fully managed service. A common requirement (the most basic one) is doing a workflow like:
Microsoft Defender for open-source relational DB
If you navigate to the overview section of your MySQL server you will see a notification area, here you will find security section. It’s basically an area to provide some hints / tips if things have not been configured such as if you have not enabled query store it may well suggest it. For this blog it is suggesting I consider a feature called Microsoft Defender.

You will find this option under the Query performance insight section of your MySQL server.
Azure DB for MySQL – Replication
No doubt there will be a need for you to split off your analytical queries from the main database for performance reasons.
