Preface

Eucalyptus continues to strive as the best on-premise AWS-compatible Infrastructure as a Service (IaaS).  One of the great things about Eucalyptus being an open source platform, is that if there is an AWS feature that any cloud administrator/developer wants to add, they have the ability to do it.  This blog entry will cover how to enable cloud users to have access to the Eucalyptus Load Balancer access logs – similar to how this is accomplished with Amazon Web Services Elastic Load...

ZFS is a filesystem designed by Sun Microsystems that focuses on data integrity.  What makes this such an attractive filesystem to use in the cloud is that a cloud user can easily do the following:

set up an LVM + RAID filesystem for storing large amounts of data (e.g. database information) expand the filesystem by adding more storage (i.e. EBS volumes) backup the filesystem without taking the filesystem offline/unmounting restore the filesystem

This blog entry will focus on how a...

As mentioned in my past blog, Eucalyptus has the concept of EUARE (IAM) Roles which pretty much work the same way as AWS IAM Roles.  This blog with discuss how to set up cross-account API access using EUARE (IAM) Roles in Eucalyptus 4.0.2.  Cross-account API access is very useful for use cases where there are multiple Eucalyptus EUARE accounts that need to access the same resources.  A great example of this can be found in the AWS IAM documentation regarding this same feature.

One of the big themes in cloud computing over the past few years has been the search for "enterprise-grade" solutions, distinguished by their levels of data control, security and performance. Businesses, especially startups, have certainly found uses for public clouds such as Amazon Web Services and Microsoft Azure, but for many organizations, some data is never going to leave the premises.

Enter the hybrid cloud. Ideally, there would be a seamless architecture spanning data centers...

What has driven OpenStack's success? The project has been a defining force in cloud computing since Rackspace and NASA founded it in 2010. This year in particular it has gained substantial traction, with Eucalyptus expressing its support a few months ago and then Hewlett-Packard - now the largest single contributor to OpenStack - acquiring Eucalyptus shortly thereafter.

It's apparent that more companies are betting on OpenStack as a path toward modern private and hybrid cloud...
