Cloud servislerine, özellikle veri saklama servisleri düşünüldüğünde, biraz büyükçe miktarlı verinin internet üzerinde transfer edilmesi bir çok kurum ve kişi için sorun yaratmakta idi. Eğer 10 Mbps'lik Internet erişiminiz varsa ve 1 TB lik verinizi hat kapasiteinizin %80 nini kullanarak servis sağlayıcıya aktarmak istedğinizde, bu işlem yaklaşık olarak 13 gün sürecektir. Amazon'nun son duyurduğu AWS Import/Export servisi bu sorunu çözmeyi hedefliyor. Bu servis sayasinde verinizi taşınabilir bir medyaya koyup Amazon'a gönderip içindeki verinin sizin için ayrılmış alana aktarımını sağlatmanız mümkün, aynı şekilde Amazon servislerindeki veriniz gönderdiğiniz medyaya yükletip size geri gönderimini sağlayabilirsiniz.
Taşınabilir medya üzerinden Import/Export yapabildiğiniz durumda veri göçü, offsite yedekleme, falekat kurtarma senaryolarını hayata geçirmek çok daha gerçekçi bir hale gelmektediri; özellikle KOBİ'ler için!
Amazon özelinde düşündüğümüzde verinizi Amazonun Avrupa yada America daki veri merkezlerine iletmek hızlı teslimat opsiyonuyla bile günler sürebilir Eğer benzer servisleri yurtiçinde sağlayan servis sağlayacılarımız olur ise bu tür servislerin Türkiyedeki adaptasyonun daha hızlı olacağını düşünüyorum. Önümüzde, deneme yanılma ile test edilmiş hazır uygulanabilir iş modeller var, tüm konuya ilgi duyan servis sağlayıcıları bu fırsatı değerlendirmeye çağırıyorum.

OpenId is decentralized and user-centric identity framework. It seems to be easy to use and implement. The number of OpenId enabled sites (consumers) supports this claim; openiddirectory.com host list of them.
Wikipedia provides good introductions about OpenId to whom are new, like me. I also found a lot of technical details at here.
Another good news is OpenSSO provides OpenId implementation under OpenSSO Extensions project; consequently we can use OpenSSO as OpenId provider as well.

Google offers a SAML-based SSO service that provides partner companies with full control over the authorization and authentication of hosted user accounts that can access web-based application like Gmail or Google Calendar. Google acts as the service provider while partners is acting as identity providers.
Google supports SAML 2.0 and any commercial and open sources software supporting SAML 2.0 (e.g; openFM) can work with it in addition to API provided by Google.
It really strike me how open standards can make life easy.
I should test Google service with OpenFM

Turkcell has been using Sun Java System Access Manager to provide Single-Signle On to the subscribers using web based VAS services. Local Sun Professional Services team developed a custom authentication module for Access Manager to be integrated with mobile signature infrastructure. Consequently, the subscribers enjoys accessing VAS services using their digital signature.

The book is about open sources. You may think there could be nothing new in such book. You are wrong!
If you are interested in what can open source means to a organization, this book is for you. Authors look at the subject from oranizational point. You understand pretty well how open source can help a company.
The most striking idea is that main advantage of open source project for a company is innovation. In a company, you have limited resources. If you share your projects with others, thousands of minds works for you. Of course, there are critical success factors in a open sources project. The book provides you a lot tips and tricks about how to prepare an environement fostering innovtion and building comminuty.
The boottomline is it is not easy to read, very boring , but the subject is pretty intereseting which makes the book readable

First trick is username. It is amAdmin -be careful it is case sensitive! Second is for the people who are familiar with Access Manager; the data store is file system not Sun directory. Do not look for directory configuration. Dennis told me the directory support will be available soon. Central repository is crucial for fail-over and load balancing. I hope it doesn't take so long.
I have documented the steps you have to complete for a successful OpenSSO server installation. You can find it in PDF format here.
Next will be agent installation! It is a real adventure, isn't it?

Tonight, I was very decisive to install opensso on my workstation. I prepared everything and setup all components (web server, directory server, etc.). Then I started to follow the instructions. It was end of a dream. It was almost impossible to setup opensso according to the provided documentation. In addition, all documentation are belong to Access Manager 7.1 and irrelevant to opensso.
I guess, our friends in the engineering were in rush, under time pressure and couldn't prepare documentation properly. It can happen. I believe they will fixed in the next days. I am ready to help as one more hand.
It seems that I have to delay my installation plan a few days....

My objectives are regarding OpenSSO;
- Discovering and elaborating OpenSSO features
- Hacking OpenSSO and sharing my experience trough quick "how to" documents so that I want to help accelerating the learn curve of developers who are interested in OpenSSO
- Discovering technical/business expansion and integration possibilities with complementary technologies and sharing them trough white papers
- Enjoy playing with OpenSSO and fun!
