Which came first: the Chicken, the Egg or the Cloud? Understanding Failover.
Imagine you’re making a pie, and the recipe says you need 6 eggs. You happen to have a box with 6 eggs, but then you drop the box…
This is where Failover comes in.
Luckily for you, you have another box with 6 eggs – this means you can still make your pie. But what if you drop that box too? This is where owning a chicken comes in handy – except chickens lay 1 egg per day so you’ll have to wait 6 days for 6 new eggs before you can make your pie, and you really can’t wait that long. So, to be absolutely certain the pie gets baked, you’d want the following:
• 2 boxes with 6 eggs each, and
• 6 chickens to simultaneously lay 6 eggs so you can bake your pie even if you’ve dropped all the eggs you had in the boxes
So, in a network environment, imagine you have one physical server (the box) and it’s hosting 6 virtual servers (the eggs). This is exactly what we found during one of our site audits for a rather large company – just one old server wheezing away under the burden of 6 virtual servers, no failover. If that server dies, the entire company of 150+ people, would come to a grinding halt, no work – no pies.
Ideally, they should have:
• 2 identically-configured physical servers, one running as Active and one running as Standby, and
• An external Cloud solution where, even if both physical servers fail (e.g. power failure, flooding etc) the 6 virtual servers can quickly and easily be spinned up in the Cloud (6 chickens laying 6 eggs).
The moral of the story is this: The eggs come first. But, at the end of the day, it’s the virtual servers that do the real work – whether they are hosted onsite on your own physical servers (the box), or hosted in somebody else’s Cloud environment (the 6 chickens). You need those eggs, pardon, virtual servers, for your business to continue functioning.
