I speak to many people who use cloud technologies, especially database tech and how little consideration they give to their MISSION CRITICAL Databases that run in the cloud and its Disaster Recovery process. When I say mission critical, I mean its relative to the company I am talking to, so what might be a tier 1 app for you might not be the case for Bob.
Let’s go back to data platforms today and I want to talk about a very common integration I see nowadays, Azure Blob Storage linked to Snowflake via a storage integration which then we can access semi structured files via external tables, it is a good combination of technology I have to say.
What do you need – the diagram gives you the high level reqs.
A common setup when leveraging the cloud is to use the cloud for Disaster recovery (DR) purposes, some say it becomes a logical extension of your on-prem / data centre (makes more sense if you use express route and private endpoints).
You can use this approach for DR of your SQL based systems, look at the below image and you can see how. (Assume the left-hand side SQL icon is a VM on prem)
Chaos engineering is fun but especially important when building solutions in the cloud. It is great leveraging the cloud to build something, whether that’s a globally distributed website with lots of traffic or an internal 3 tier application for a business – the question is – what happens is there is an unexpected fault / disruption? Can your system / app withstand the issue?
We all would like to save money when operating in the cloud, Microsoft has released a stop / start concept for SQL Managed Instances – preview mode!
