Cloud Computing

The term cloud computing has been tossed around in the computing world with a lot of different meanings. In HPC some researchers use the cloud to run all of their applications, and not have to worry about the cost to purchase, run and maintain their own hardware. Other researchers will use the cloud as a “Cloud Burst.” This can be done in different ways depending on how much resources are needed, and how much a researcher is willing to pay. Finally, some Data Centers will have their own clouds for their users. This allows users to set up their own “space” for their research that can be deleted, changed, or saved for later. It also allows for different Operating Systems to be used for their research. For instance, it’s not trivial to put a Windows Database on an HPC Cluster, but it is to do so in the cloud. At Aspen Systems, we have the ability to help you set-up your cloud infrastructure, and match up the hardware with the software to fit your needs.

Open Source Creation of Private and Public Clouds

To help you streamline the management of your HPC systems, Aspen Systems has partnered with OpenStack, a cloud computing operating system that controls large pools of HPC resources throughout a data center. OpenStack provides systems administrators with a dashboard for controlling large pools of networking, computing and storage resources. OpenStack can also be managed and controlled via the OpenStack API for the enablement of complete system integration.

How is OpenStack used in a cloud environment?

The cloud is all about providing computing for end users in a remote environment, where the actual software runs as a service on reliable and scalable servers rather than on each end-user’s computer. Cloud computing can refer to a lot of different things, but typically the industry talks about running different items “as a service”—software, platforms and infrastructure. OpenStack falls into the latter category and is considered Infrastructure as a Service (IaaS). Providing infrastructure means that OpenStack makes it easy for users to quickly add new instance, upon which other cloud components can run. OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneous infrastructure.

“As we examined the various initiatives we’d have underway in our cloud, which would include the intermingling of physical and virtual loads as well as complex network configurations, we knew that the flexibility inherent in OpenStack would prove powerful enough to support our objectives. With OpenStack we have the ability to customize the platform and maintain significant control over our destiny.”

Open Source Cloud Computing

CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.

CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution. Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured RESTful API.

Features and Functionality

Apache CloudStack is a Java-based project that provides a management server and agents (if needed) for hypervisor hosts so that you can run an IaaS cloud. Some, but not all, of the features and functionality provided by CloudStack:

  • Works with hosts running XenServer/XCP, KVM, Hyper-V, and/or VMware ESXi with vSphere
  • Provides a friendly Web-based UI for managing the cloud
  • Provides a native API
  • May provide an Amazon S3/EC2 compatible API (optional)
  • Manages storage for instances running on the hypervisors (primary storage) as well as templates, snapshots, and ISO images (secondary storage)
  • Orchestrates network services from the data link layer (L2) to some application layer (L7) services, such as DHCP, NAT, firewall, VPN, and so on
  • Accounting of network, compute, and storage resources
  • Multi-tenancy/account separation
  • User management

In short, organizations can use Apache CloudStack to deploy a full-featured public or private IaaS cloud.
