SASE導入の必要性
The defining moment. He was searching for a way out of his confusion.
I'm trying to see the demolition, but all I see is more construction.
I'm missing the first principle.
Instead, he was handed a compass that only pointed deeper in.
You're staring at a blueprint for a skyscraper and asking about the color of the paint.
Until you can write a rhyme about a CI packet, don't talk to me about the lyric.
Okay team, let's get straight to the point.
Our current VPN X2000 appliances are reaching end of life next year.
We can simply replace them with the new X3000 model,
but I believe this is a critical opportunity for a bigger architectural shift.
Especially considering the feedback from our APAC users.
The performance complaints during peak hours are becoming impossible to ignore.
The SASE vision sounds great, Liam.
I've heard similar promises before,
but let's not forget the Firefly project three years ago.
We have legacy apps hard-coded to expect internal IPs.
If we don't map out every single dependency,
a sudden shift won't just be an outage, it'll be a catastrophe.
You're right, Sarah. Firefly was a catastrophe.
A beautiful, expensive catastrophe.
SASEへの移行の心理的障壁
Why?
Why?
Because we tried to patch a leaking dam with brand new wallpaper.
Those hard-coded dependencies you're worried about?
They're just cracks in the wall.
The real disease is the castle and moat itself.
We're not here to patch cracks.
We're here to tear down the walls.
Cracks in the wall, disease.
They're not talking about devices anymore.
They're talking about a philosophy.
A philosophy that's written in a language I can't read.
Liam's point is fundamental, I agree.
But to ensure a smooth transition, we can't ignore the user's perspective.
Tanaka-san, what do you see as the biggest psychological barrier
for our users in this kind of shift?
Uh, well, I think users have a ritual.
They connect to the office.
It's a tangible action.
Taking that away, it might feel like we've taken away the front door to their house,
even if the house itself is everywhere.
It could be unsettling.
He's right.
That ritual is about control and certainty.
In the Firefly project, we focused so much on the back-end logic
that we forgot the users felt like we'd moved their house without telling them.
Tanaka's point isn't trivial.
ユーザー体験とパフォーマンスの重要性
Users don't care about the architecture of the house.
They care that the lights turn on.
If their applications run faster and there are fewer locked doors,
they won't mourn the loss of a key they had to jiggle every morning.
We prove superiority with performance, not poetry.
Tanaka's point about the user's ritual is important.
It's a psychological barrier we can't ignore.
And Liam is right that overwhelming performance is the only way to overcome that barrier.
We need to make the new experience so seamless, so fast.
That they don't even miss the old way.
Let's make that our goal for the POC.
Okay team, let's start drafting the plan for the Singapore pilot.
SASEの理解と構成要素
We'll focus on measuring both performance gains and user sentiment.
I'm drowning.
Drowning in a sea of jargon.
Every article I read is a door that leads to 10 other locked doors.
I don't need another article.
I need a key.
I need a map.
Excuse me, Liam-san.
Sorry to bother you when you're focused.
What is it?
It's about the Casalan moat.
I think I understand the concept, but when I look at the SASE components,
ZTNA,
SWIG,
CASB,
SASEの理解に向けた基礎知識
it just looks like you're replacing one big wall with dozens of smaller, high-tech fences.
I'm trying to see the demolition, but all I see is more construction.
I'm missing the first principle.
You're staring at a blueprint for a skyscraper and asking about the colour of the paint.
Paint?
What's the third layer of the OSI model?
Uh, the network layer.
And what does it do?
Don't tell me what it's for.
Tell me what it does.
It moves packets.
Based on addresses.
Right, it moves packets.
It doesn't know about applications.
It doesn't know about users.
It doesn't know trust.
It just moves packets.
That's a brick.
You're trying to debate architecture when you don't respect the brick.
Half-baked knowledge is a liability, Tanaka.
SASE's poetry, yes.
But you can't read poetry if you don't know the alphabet.
The OSI model, TCPIP, the journey of a single packet.
That's your alphabet.
Go learn it.
Until you can write a rhyme about a CI packet, don't talk to me about the lyric.
