Today I did my first install of CEPH, which I used as backend system for the Elastic Block Storage (EBS) in Eucalyptus. The advantage of CEPH is that it is a distributed system which is going to provide you replication (persistence for data), redundancy (we are using a pool of resources, not a single target) and scalability : the easiest way to add capacity is to add nodes which will be used for storage, and...

The Eucalyptus Management Console can be deployed in a variety of ways, but we’d obviously like it to be scalable, highly available and responsive.

Introduction

My last few blogs have discussed how Eucalyptus 4.0 supports similar Amazon Web Services, such as Elastic Compute Cloud (EC2), Simple Storage Services (S3), Elastic Load Balancing (ELB) and Security Token Services (STS) features. Using third party tools, such as python boto and s3cmd, features such as listing buckets and objects, listing running instances and assuming IAM roles were covered.  This blog entry is yet another example as to how Eucalyptus provides AWS compatible...
