"조금 복잡해 보인다"는 알량한 이유로 시험을 위해 설치만 한 후 방치해버린 서버 가상화/클라우드 컴퓨팅 솔루션이 하나 있는데, 그 "알량한 이유"가 합당치 않으므로... 다시 기억을 되새긴다. 물건일 것 같다. 언제든 꼭 확인하라.

OpenNebula is an open and flexible tool that fits into existing data center environments to build any type of Cloud deployment. OpenNebula can be primarily used as a virtualization tool to manage your virtual infrastructure in the data-center or cluster, which is usually referred as Private Cloud. OpenNebula supports Hybrid Cloud to combine local infrastructure with public cloud-based infrastructure, enabling highly scalable hosting environments. OpenNebula also supports Public Clouds by providing Cloud interfaces to expose its functionality for virtual machine, storage and network management.

Eucalyptus에 관한 이야기 몇 개 더.

Eucalyptus enables the creation of Private Clouds that can interface with Amazon Web Services API, which they view as the de-facto standard. The Enterprise edition, first released in September 2009, is fully compatible with Amazon EC2 and S3, whereas the open-source version supports almost all functions of EC2 and a limited set of S3. Enterprises can create hybrid Clouds with data and virtual machine images that can be seamlessly accessed from Eucalyptus clouds and Amazon's Elastic Compute Cloud and Simple Storage Service.

As I'm sure you've heard by now, Nebula's Infrastructure-as-a-Service layer is powered in major part by Eucalyptus, an open-source software system for managing cloud systems that came out of UC Santa Barbara. The key selling point of Eucalyptus is that it provides API compatibility with Amazon's EC2 web service. This means that creating and managing virtual machines in Nebula will be as easy as using Amazon EC2.

알려진 바와 같이, 우분투 리눅스의 새 버전인 9.10 Karmic Koala는 오픈소스 클라우드 컴퓨팅 플랫폼인 Eucalyptus를 포함하고 있다. 캐노니컬의 진로를 보여주는 예이자, 오픈소스 기반 클라우드 컴퓨팅 사례의 적절한 형태 중 하나. 유칼립투스는 제공하는 기능의 제한으로 인하여 사용을 보류하고 있지만, 분명 의미있는 솔루션 중 하나. 지켜볼 것.

The latest version of Ubuntu Server (9.10) includes the Ubuntu Enterprise Cloud (UEC), which is actually powered by Eucalyptus. The ability to deploy a “cloud” on any server running Ubuntu is really quite amazing, especially given the compatibility of Eucalyptus with Amazon and the plethora of application images available for nearly immediate deployment. It supports both a public and private option, and a hybrid model, and comes replete with management tools designed to make building, deploying, and managing your own personal, private cloud a breeze.

Koalas love eucalyptus, they spend three hours a day munching away on the sturdy plant. Likewise, Ubuntu 9.10 Karmic Koala loves Eucalyptus, the Open Source system for implementing on-premise private and hybrid clouds using the hardware and software infrastructure that is in place, without modification. This allows you to run your own private cloud on your own hardware and infrastructure. Sound interesting? It really is, and this a rocking new feature in the new Ubuntu Server edition.

EC2, S3 등을 시작으로 계속해서 새로운 서비스를 발표하면서 클라우드 컴퓨팅 산업을 선도해오고 있는 Amazon이 이번엔 Relational Database 를 역시 "서비스로써" 선보였다. 깜짝 깜짝... 재미있고, 은근히 시샘도 나고... 그렇다.

Amazon Relational Database Service (Amazon RDS)

Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.

Amazon RDS gives you access to the full capabilities of a familiar MySQL database. This means the code, applications, and tools you already use today with your existing MySQL databases work seamlessly with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period. You also benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your relational database instance via a single API call. As with all Amazon Web Services, there are no up-front investments required, and you pay only for the resources you use.

Introducing Amazon RDS - The Amazon Relational Database Service

We are always looking for ways to make it faster, simpler, and more fun to develop applications of all types. Every hour that you don't spend fiddling with hardware, tracing cables, installing operating systems or managing databases is an hour that you can spend on the unique and value-added aspects of your application.

Ruby on Rails 개발자를 겨냥한 상용 PaaS(Platform as a Service) 서비스이다. 대충 봐도 멋지네! 다음에 찬찬히 들여다보자.

Heroku is a platform for instant deployment of Ruby/Rails web apps.

Heroku is a completely novel approach to deploying web applications. Forget about servers; the fundamental unit is the app. Use the Heroku client gem to create and manage apps from the command line. Then deploy your code with Git, and control the running app with the remote Ruby console and rake commands.
