Back when I was taking up my current role, Minister of Science and Technology

Past simple

Future simple

"Mr.Chang, are you convinced that cloud computing will be successful in Taiwan?"

It wasn't that we had no hope for success at all,

Actually Ben already touched on this topic.

So what I want to report today are the challenges that we encountered,

and what are the preconceptions that we need to change.

Is it safe to store our data on the cloud?

Let's first talk about 50, 100 years ago, when banks first opened.

Our old folks who lived through that time

were taking money out from under the bed and depositing them into the banks.

After putting money into the banks, some folks even commented on the fact that

weren't the exact same notes that they deposited!

Today, I can put a computer into a data center.

But when I'm accessing the data center, I may not be using the same computer.

Some may feel that they lost out because they don't get to use their own computer.

But when you deposit an old bill into the bank

and get a new bill in return, you wouldn't think of that as "losing out"

Today, people who have lots of gold and jewellery

Because the bank promises to give you a safer environment than your home, right?

Today, when we put our data onto the cloud,

the operators have to be able to give you a safer environment than your home.

Then you might ask me: I can control everything at my own company

then he wouldn't be doing this for a living. So of course he can.

Second myth: the utilities at cloud data centers are very expensive

The electric bill at Acer's data center is 400 million Taiwanese Dollars every year.

Our basement water tank holds 6000 tons of water.

Some people say that this is not environmentally friendly.

Why do we encourage people to take buses nowadays?

How far can a bus run on a liter of fuel?

With your own hybrid car you can probably go 10km on that same liter of fuel.

Then why are we encouraging you to take the bus instead of driving your car?

Because the bus has the economy of scale.

Likewise, today we are encouraging people to put their computers into data centers

and through the economy of scale in the data center

we can reduce the average amount of power and water used up by individual computers.

But some people like my previous boss, Chairman J.T. Wang says:

"But then all that carbon footprint becomes Acer's! That's unacceptable!"

It's true that we don't yet have a standardized way

But of course Acer alone can't bear the entire carbon footprint.

The carbon footprint should be apportioned

to the users of the data center based on how much electricity they use.

Similarly for Google's data center in Chang Hua County, which you mentioned.

Google's annual electric bill will be at least 2 billion for sure.

So whose carbon footprint is it? Google's? Or Taiwan's?

Google may be using this data center to serve other Asian countries

The carbon footprint should go to them, not Taiwan.

Taiwan is doing it's part for the environment by running this data center.

when we were selling tickets for A-Mei's concert,

the computer hanged before we could finish selling the tickets.

A few years ago, we were selling train tickets for the eve of Chinese New Year.

But the server hanged before we could finish selling.

These are not hardware problems. They are software issues.

We see a lot of apps being written by almost everyone nowadays and so we ask:

If you could write handphone apps, then why not software?

Let me ask you, when you're running Angry Birds on your handphone,

how many people are using that software? Just you, right?

But when we are selling train tickets on the eve of Chinese New year

how many people are trying to buy those tickets?

At least thousands if not tens of thousands.

A software meant for thousands of simultaneous users

is very different from a software written for just one user.

That's a good question. No one knows the answer.

It's a very basic function and writing it seems to be pretty easy.

But if you see how many people in Google are working on Gmail

you wouldn't want to try and create a competing email software.

The Gmail department by itself pretty much takes up an entire building.

So this tells us that developing software isn't so easy.

Most importantly, transactional behavior is a problem without a technical solution.
