Sun and Oracle - the new stack for the customer

Big news on April 20 of 2009!

As a Sun employee, I am really sad to hear the news of "Oracle buys Sun". But the new stack that is only possible thru the acquisition will provide unprecedented "enterprise and open" stack for enterprise applications - applications down to OS, servers and storage.

I hope it provides new value and new economics for the customers. Actually that might be the only scenario where the technical pieces from both parties are fit together to build a complete enterprise stack - an eye opener for the customers. Or it could be serviced or provided in the form of cloud computing or cloud service. Just my very personal guess. If there is anything that could be called an enterprise-class cloud platform, who else could provide it other than "Sun+Oracle" combo?

Here's the high level sketch of the stack. Let's how it actually pans out over the course of time.

One thing for sure is Sun+Oracle might be the least painful or least destructive combination from the evolutional angle of amazing suites of Sun technologies if Sun is to be combined with other IT titans in order to provide better value for the shareholders in the longer run.

April 20, 2009 will be remembered as the end of old IT paradigm and the start of new IT paradigm. Let's look back at this in a couple of years how the vision becomes a reality for the customers.

IT evolves for simplicity! (IT diverges for features and IT converges for simplicity!) - It's a simple MJ's Law which is the summary of my own observation and contribution to the IT over the last 25 years.

a studio-quality hifi system at home

The Hifi systems setup you see below is a result of my effort to bring studio-quality professional system into my home. 

The speaker is heavy (close to 100kg or 200 pounds) and big with two 15" woofers (low frequency speaker unit) in it. You might ask 'where is mid or high frequency units?'. A very good question! Tannoy speaker is renowned for dual-concentric unit which encloses a high frequency horn unit right into low frequency unit. Look at upper speaker unit, you will find a small hole in the center from which high frequency sound is coming behind.

The speaker is powered by another studio-quality power amplifer from Crest Audio. The amp boast more than 400 watts per channel. Enough to rattle the whole apartment. Living in an apartment unit, I can never push my system to that exterme.  

Though this speaker is unbelievably fast and accurate, the sound is on the dry side. I like a bit of warmth in the sound. So I matched it with a tube preamplifier which adds a juice of warm into the final sound.

My quest for ultimate sound (without spending a fortune) continues ...

Intel Nehalem CPU 발표 그리고 썬

2009년3월31일 인텔의 제온5500(코드명 네할렘 Nehalem) 발표장에 초대받아 갔습니다.

새로운 cpu가 발표할때마다 그전 세대의 cpu와 비교하여 성능향상이 있다는 것은 전혀 놀라운 사실이 아니죠. 널리 잘 알려진 소위 무어의 법칙처럼 대략 1년반-2년마다 약 두배의 집적도 또는 성능향상이 있어왔습니다.

그런데 이번 네할렘 발표는 그 어느신제품보다도 인텔의 기술향상 또는 혁신이 잘 적용된 훌륭한 제품발표라고 생각합니다. 그 동안 인텔 cpu의 상대적약점으로 지적되어 온 메모리관련구조를 획기적으로 개선되었네요. 이 때문에 memory intensive application의 경우 4-5배의 성능향상을 보이기도 합니다. 그 이외에도

• 에너지 절약, 전원관리 기능 개선


• 가상화기능개선

등이 눈에 띱니다.

썬마이크로시스템즈는 이러한 cpu의 혁신을 최대화하기 위하여

• 이 cpu를 채택한 다양한 제품발표 (요것에 대하여 자세한것은 몇주 후에...)


• 세계에서 가장 진화된 OS인 솔라리스의 최적화

를 인텔측과 함께 작업하여왔습니다. 제품과 솔라리스 최적화에 대해선 별도 블로그에서 한번 다루도록 하겠습니다.
