Three Shades of Data in the Public Cloud There is continued and escalating hype about "Big Data" and the cloud services that empower big data analytics.  But to better understand and demystify this hype, whether exploring Big Data or traditional, structured or unstructured, we need to categorize cloud data into three primary forms. Aggregate Cloud Data Aggregate form of cloud data - whether public, hybrid or private - is especially popular with multi-site organizations.  Data collected in different locations needs to be processed at some point and using the cloud to aggregate data in a common location is commonsensical for future processing or analytics. Aggregate cloud data has actually been around even before we thought of cloud-computing as we know it today.  A very popular use case of this is in organizations with branch offices, such as retail and financial fir...

Containers in the Cloud By @Nimbix | @CloudExpo [#Cloud]

What's hot in today's cloud computing world? Containers are fast becoming a viable alternative to virtualization for the right use cases. But to understand why containers can be a better option, we need to first understand their origins. In basic terms, containers are application-centric environments that help isolate and run workloads far more efficiently than the traditional hypervisor technology found in commodity cloud Infrastructure as a Service. Modern operating systems (Linux, Windows, etc.) are made up of two basic parts: kernel space and user space. As its name implies,... (more)

Big Compute Gives Life to New Data By @Nimbix | @CloudExpo [#BigData]

What's Big Data without Big Compute? Basically just a large collection of unstructured information with little purpose and value.  It's not enough for data just to exist, we must derive value from it through computation - something commonly referred to as analytics. The Quantum Nature of Big Data With traditional data, we simply query it to derive results; all we need is currently stored within the data set itself.  For instance, for a customer database with dates of birth, we may just fetch the list of customers who were born after a certain date.  This is a simple query, not a c...

HPC Cloud Anatomy 101 By @VirtualLeo | @CloudExpo [#Cloud]

When it comes to cloud computing, there is no "one size fits all" platform for getting work done.  High Performance Computing (HPC) workloads are not web applications. Thankfully, there are clouds specifically designed for running HPC workloads rather than web applications. An HPC cloud is very different to a commodity web services cloud. Before we discuss how an HPC Cloud is architected, we need to examine HPC workloads themselves to really understand how they differ from other applications: HPC jobs process data - most often enormous amounts of data (Big Data) and return result...
