I'm currently managing a hybrid environment with four data centers—two in Azure and two on-premises. As we approach the new year, I'm considering whether it's wise to eliminate the two on-prem data centers entirely. I'm curious about the current thinking on hybrid setups versus fully cloud-based solutions. Is it a bad idea to remove on-prem data centers, or are there important considerations I should be aware of? Thanks in advance!

Before making any decisions, you should assess your specific environment. For example, can your vital on-prem systems function without constant connectivity to the data centers? If Azure went down entirely, would your operations still be able to maintain functionality? It's crucial to understand how much downtime you can tolerate and what services rely on your current setup in case of an outage.
I'd recommend keeping at least two on-prem data centers in different locations and environments. Just relying on two in Azure isn't sufficient. Redundancy is key, and using different regions or even hybrid setups might be wiser to ensure that you have backup options if something goes wrong in the cloud.
That's a good point! However, keeping two data centers in Azure can be a solid plan as long as you deploy them across different regional zones to prevent a single point of failure.
If you're still running Active Directory on-prem to support local clients, transitioning everything to cloud services might not make sense. The operational costs on cloud VMs can quickly outweigh maintaining a small local server setup. In many cases, moving all your data centers to IaaS might result in higher expenses without real benefits—plus, managing a more complex system can introduce new points of failure.
That's true! I did my own cost analysis, and keeping a couple of on-prem servers has proven to be more economical than going fully cloud. In my case, having on-prem solutions ensures everything continues to function flawlessly, even when there's an internet interruption. It feels much safer knowing my environment remains stable.
If your organization primarily deals with administrative tasks like document handling, consider moving towards a more cloud-centric approach. But if you're in a more industrial setting, preserving your on-premises Active Directory is essential. Ultimately, it depends on what your organization does and how critical IT reliability is to your operations.
If your ultimate goal is a total shift to the cloud, it's essential to define what that actually entails. Randomly deploying data centers in cloud environments without a clear plan is just wasteful. You need to get clarity on your needs and what aspects of your operations truly require datacenter support.
Exactly! It's not just about a total Azure outage; you have to consider WAN outages too. Plus, if you can't authenticate to your virtualization stack like Hyper-V or VMware, you risk being unable to do a manual failover. Understanding your clients' needs is crucial, especially if they're small outfits like a dental office. They might not need heavy infrastructure but managing downtime is different for everyone.
