Look before you leap: Evaluating cloud migrations in high-performance LAN environments
September 24th, 2013, by Seth Miller
Seth Miller demonstrates why its crucial to gather all the relevant data about how your systems are used before moving anything to the cloud.
Using cloud based file storage, sync, and collaboration systems is very popular, and a great fit for a lot of organizations of all sorts and sizes. Here’s the catch, though: If you’re in an environment where users are doing more than email and basic office apps, the cloud doesn’t always make sense – and evaluating the viability of a move to cloud can be very difficult.
Let’s bring this a bit closer to the ground. You’re in IT for a group working in media production.
- You may have as few as 40 or 50 total users – but you wouldn’t know it from looking in the server room. That probably looks more like a “typical business” with 250 or more users. Dozens or hundreds of terabytes, lots of servers (physical or virtual, doesn’t matter).
- You’re dealing with big files (video, high fidelity audio, high res images, etc).
- You’re not 100% Windows at the desktop. You’ve got a split of Macs and Windows, maybe even a few Linux boxes.
- You’ve had SANs/NAS/large DAS RAIDs for many years by the time 2013 rolled around. When GigE LAN became standard, productivity soared.
- Let’s assume you don’t have a multi-gigabit internet connection, for sake of discussion.
My friend, if this all sounds familiar, you are in a textbook high-performance LAN environment. Assuming you don’t have a multi-gigabit connection to the internet, you may have a real problem moving to the cloud.
