VMware Administrator – what is your next goal? 99% will answer it like Cloud.
Then which Cloud to learn? Amazon? RackSpace?
Wait they do not have any Hypervizor products 🙂 but they are Leaders to provide cloud space. Let us concentrate and learn some basics of this new era OpenStack.
“OpenStack is a collection of open source software projects that can be collectively utilized to operate a Cloud network Infrastructure in order to provide IaaS”
What is Keystone?
Keystone is the identity service used by OpenStack for authentication (authN) and high-level authorization (authZ). It currently supports token-based authN and user-service authorization. It has recently been rearchitected to allow for expansion to support proxying external services and AuthN/AuthZ mechanisms such as oAuth, SAML and openID in future versions.
What is Neutron?
Neutron is an OpenStack project to provide “networking as a service” between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).
Starting in the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an “incubated” project, which means use is suggested only for those who really know what they’re doing with Neutron).
What is Swift?
The OpenStack Object Store project, known as Swift, offers cloud storage software so that you can store and retrieve lots of data with a simple API. It’s built for scale and optimized for durability, availability, and concurrency across the entire data set. Swift is ideal for storing unstructured data that can grow without bound.
What is Glance? (Image Service)
Provides Storage for Virtual disk, kernel and images. Glance is also used to provide image registration and querying services. It is able to accept images in many formats, including the popular Amazon Machine Image (AMI), Amazon Kernel Image (AKI) and Amazon Ramdisk Image (ARI)
What is Cinder?
Cinder is a Block Storage service for OpenStack. It’s designed to allow the use of either a reference implementation (LVM) to present storage resources to end users that can be consumed by the OpenStack Compute Project (Nova). The short description of Cinder is that it virtualizes pools of block storage devices and provides end users with a self service API to request and consume those resources without requiring any knowledge of where their storage is actually deployed or on what type of device.
What is Heat?
Heat is the main project in the OpenStack Orchestration program. It implements an orchestration engine to launch multiple composite cloud applications based on templates in the form of text files that can be treated like code. A native Heat template format is evolving, but Heat also endeavours to provide compatibility with the AWS CloudFormation template format, so that many existing CloudFormation templates can be launched on OpenStack. Heat provides both an OpenStack-native ReST API and a CloudFormation-compatible Query API.
What is Trove?
Trove is Database as a Service for OpenStack. It’s designed to run entirely on OpenStack, with the goal of allowing users to quickly and easily utilize the features of a relational or non-relational database without the burden of handling complex administrative tasks. Cloud users and database administrators can provision and manage multiple database instances as needed. Initially, the service will focus on providing resource isolation at high performance while automating complex administrative tasks including deployment, configuration, patching, backups, restores, and monitoring.
What is Ironic?
OpenStack Bare Metal Provisioning a.k.a Ironic is an integrated OpenStack project which aims to provision bare metal machines instead of virtual machines, forked from the Nova Baremetal driver. It is best thought of as a bare metal hypervisor API and a set of plugins which interact with the bare metal hypervisors. By default, it will use PXE and IPMI in concert to provision and turn on/off machines, but Ironic also supports vendor-specific plugins which may implement additional functionality.
What is Sahara?
The Sahara project provides a simple means to provision a data-intensive application cluster (Hadoop or Spark) on top of OpenStack. It’s the ex Savanna project, renamed due to potential trademark issues.
What is Zaqar?
Zaqar is a multi-tenant cloud messaging service for web developers. It combines the ideas pioneered by Amazon’s SQS product with additional semantics to support event broadcasting. The service features a fully RESTful API, which developers can use to send messages between various components of their SaaS and mobile applications, by using a variety of communication patterns. Underlying this API is an efficient messaging engine designed with scalability and security in mind. Other OpenStack components can integrate with Zaqar to surface events to end users and to communicate with guest agents that run in the “over-cloud” layer. Cloud operators can leverage Zaqar to provide equivalents of SQS and SNS to their customers.
What is Barbican?
Barbican is a ReST API designed for the secure storage, provisioning and management of secrets. It is aimed at being useful for all environments, including large ephemeral Clouds. All documentation and work can be found on either Launchpad or Github at the following locations:
- Source Code
What is Designate?
Designate provides DNSaaS services for OpenStack:
- REST API for domain/record management
- Support for PowerDNS and Bind9 out of the box
- Integrated with Keystone for authentication
- Framework in place to integrate with Nova and Quantum notifications (for auto-generated records)
