Partly Cloudy

We have a dream
A vision
An aspiration
To compute in the cloud
To pay as we go
To drink by the sip
To add cores at our whim
To write to disks with no end
To scale up with demand
And scale down when it ends
Elasticity
Scalability
Redundancy
Computing as a utility
This is our dream
Becoming reality

But…
There’s a hitch.
There’s a bump in the road
There’s a twist in the path
There’s a detour ahead on the way to achieving our goal

It’s the Database
Our old friend
He is set in his ways
He deals in transactions to keeps things consistent
He maintains the integrity of all his relations
He eats disks for breakfast
He hungers for RAM
He loves queries and joins, and gives each one a plan
He likes his schemas normal and strict
His changes are atomic
That is his schtick

He’s an old friend as I said
We all know him well
So it pains me to say that in this new-fangled cloud
He doesn’t quite fit

Don’t get me wrong, our friend can scale as high as you want
But there’s a price to be paid
That expands as you grow
The cost is complexity
It’s more things to maintain
More things that can go wrong
More ways to inflict pain
On the poor DBA who cares for our friend
The one who backs him up and, if he dies, restores him again

I love our old friend
I know you do too
But it is time for us all to own up to the fact
That putting him into the cloud
Taking him out of the rack
Just causes us both more pain and more woe
So…
It’s time to move on
Time to learn some new tricks
Time to explore a new world that is less ACIDic

It’s time to meet some new friends
Those who were born in the cloud
Who are still growing up
Still figuring things out
There’s Google’s BigTable
and Werner’s SimpleDB
There’s Hive and HBase and Mongo and Couch
There’s Cassandra and Drizzle
And not to be left out
There’s Vertica and Aster if you want to spend for support
There’s a Tokyo Cabinet and something called Redis I’m told

It’s a party, a playgroup of newborn DB’s
They scale and expand, they re-partition with ease
They are new and exciting
And still flawed to be sure
But they’ll learn and improve, grow and mature

They are our future
We developers should take heed
If our databases can change, then maybe
Just maybe
So can we
