Migrating Node.js apps from AWS EB to Heroku

Danger

This post was written when I had little experience with Node.js. This is not an advisable way. This post simply serves as a departure post for my journey.

Node.js 앱을 AWS EB에서 Heroku로 옮기기

I have used AWS Elastic Beanstalk for a while and figured Heroku has several advantages over AWS. So I have migrated my AWS EB app called KMLA Forms to Heroku. For your information, KMLA Forms is a web app that simplifies writing necessary official documents in my school, KMLA.

Few advantages I found:

Money. AWS costs money after its free tier limit. Since some of the students in my school used my web app, I have got some traffic, and AWS started to ask me about ~$10/month. As far as I know, there is no free tier traffic limit on Heroku.
Native HTTPS support. Heroku natively supports HTTPS since every dyno app can use Heroku's domain. AWS EB, on the other hand, does not provide this. You need to configure your web domain and HTTPS Certificate for each web domain. Not valid for casual developers.

I had to make only minimal changes to app.js and package.json.

AWS Version

Heroku Version

Also, I have added "start": "node app.js" in package.json. Codes are on GitHub, and the web is launched here.

컴퓨트로늄 정의

컴퓨트로늄이 뭐야?

컴퓨트로늄(computronium)은 계산을 수행하는 데 최적으로 설계된 가상의 물질이다.

쉽게 말하면, “물질을 최대한 컴퓨터처럼 만든 것”이다. 일반 컴퓨터는 실리콘 칩, 전선, 냉각 장치, 케이스처럼 계산에 직접 쓰이지 않는 부분이 많다. 컴퓨트로늄은 그런 낭비를 극단적으로 줄이고, 물질의 질량·에너지·구조 전체를 계산에 쓰도록 만든다는 개념이다.

예시로는 다음이 있다.

행성 전체를 컴퓨터로 바꾼 구조
별의 에너지를 둘러싸서 계산에 쓰는 거대 컴퓨터
인간 뇌보다 훨씬 조밀한 인공 신경망 물질
우주 전체를 계산 장치처럼 재구성한다는 극단적 미래 시나리오

이 개념은 주로 SF, 미래학, 인공지능 이론, 트랜스휴머니즘, 우주공학적 상상에서 나온다.

핵심은 이것이다.

컴퓨트로늄 = 계산 효율을 극한까지 높이기 위해 재구성된 물질

현실에 아직 존재하는 물질 이름은 아니다. 물리학적으로 가능한 한계, 열 방출, 에너지 공급, 정보 저장 밀도 같은 제약 때문에 실제 구현은 가설 수준이다.
