OpenStack is an Infrastructure as a Service offering. (see my prior post for an explanation of IaaS).
OpenStack is an OpenSource project, founded by RackSpace, NASA and others.
OpenStack can be deployed as a public or private cloud.
The OpenStack projects are: CINDER, GLANCE, KEYSTONE, NOVA, QUANTUM, SWIFT.
OpenStack Compute: (NOVA)
Project NOVA, or OpenStack Compute, provisions and manages on-demand virtual machines and associated resources: CPU, Memory, Disk and Network.
Virtual machines can be started, stopped, suspended, created and deleted, while network options for a virtual machine are static, DHCP, or IPv6.
The virtual machines run on hypervisors such as XEN or KVM, but others are supported too - even VMware ESXi!
Users and administrators use the GUI to request virtual machines, while developers may typically use an API.
Security? Of course there are security groups, similar to AWS, to control access to virtual machines and RBAC to govern user access by role and project.
Object Storage (project SWIFT)
Object Storage is a distributed storage system for static data such as files (graphics, movies) and virtual machine images. Objects and files are written to multiple disk drives, while OpenStack is responsible for ensuring data replication and integrity. Storage scales horizontally by adding new servers. If a server or hard drive fails, OpenStack replicates its content from other active servers to new servers in the cluster. Since OpenStack uses software to ensure data replication and distribution across servers, inexpensive servers can be used rather than expensive storage hardware.
Block storage (project CINDER)
Block storage is essentially volumes used by OpenStack virtual machines. Snapshots back up data stored on block storage volumes. Snapshots can be restored or used to create a new block storage volume.
Network (project QUANTUM)
OpenStack provides networking models to accomodate different applications or users. Standard network models include flat networks or VLANs to separate servers and network traffic. OpenStack Networking manages IP addresses, to allocate static or DHCP addresses. Floating IP addresses allow traffic to be dynamically rerouted to any compute resource, for example to redirect traffic during maintenance or in the case of a failure. OpenStack Networking has an extension framework to add intrusion detection systems (IDS), load balancing, firewalls and virtual private networks (VPN) .
Identity services (project KEYSTONE)
OpenStack Identity provides a central repository of users mapped to the OpenStack services they can access. OpenStack identity is a common authentication system and integrates with existing backend directory services such as LDAP. It supports several forms of authentication including username and password, tokens and AWS-type logins. The identity service also provides a queryable list of services deployed in the OpenStack cloud and users can programmatically determine their level of access. OpenStack.
OpenStack Administrators can:
- Configure centralized policies across users and systems
- Create users and tenants and define permissions for compute, storage and networking resources using role-based access control (RBAC)
- Integrate with an existing directory like LDAP, allowing for a single source of identity authentication across the cloud.
Image services (Project GLANCE)
The OpenStack Image Service provides discovery, registration and delivery services for disk and server images. Saved images can be used as a template to get new virtual servers up and running (especially useful for multiple servers of the same type and configuration). It can also be used to store and catalog an umlimited number of backups.
The image service stores private and public images in a variety of formats:
- qcow2 (Qemu/KVM)
- OVF (Open Virtualization Format)
- VDI (VirtualBox)
- VHD (Hyper-V)
- VMDK (VMWare)

Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using ...

The Domain Name Service (DNS) is one of the most important components in networking infrastructure, enabling users and services to access applications by translating URLs (names) into IP addresses (numbers). Because every icon and URL and all embedded content on a website requires a DNS lookup loading complex sites necessitates hundreds of DNS queries. In addition, as more internet-enabled ‘Things' get connected, people will rely on DNS to name and find their fridges, toasters and toilets. Acco...

The term culture has had a polarizing effect among DevOps supporters. Some propose that culture change is critical for success with DevOps, but are remiss to define culture. Some talk about a DevOps culture but then reference activities that could lead to culture change and there are those that talk about culture change as a set of behaviors that need to be adopted by those in IT. There is no question that businesses successful in adopting a DevOps mindset have seen departmental culture change, ...
