With growing technology, the business world is becoming more virtualized and gradually data storage has moved on from papers to computers and now to cloud.
The first thing that anyone considering cloud would learn is that cloud provides optimal IT infrastructure. With growing competition, cloud technology is shedding its complexity while becoming more adept. Due to its huge benefits, cloud is largely used by organizations and therewith comes the privacy and security concerns. When it comes to considering cloud, a lot of things go into it- from cost-effectiveness to deployment of resources, expert manpower etc. The leading internet marketing services provider, Chakra Systems, offers a wide range of IT and IT-based outsourcing solutions.
Oracle Solaris 11 includes a complete OpenStack distribution called Oracle OpenStack for Oracle Solaris. OpenStack on Oracle Solaris 11 does not have any special system requirements other than those spelled out for Oracle Solaris itself. After installation and a small amount of customization, VMs, otherwise known as Nova instances, can be created, assigned block storage, attached to virtual networks, and then managed through an easy-to-use web browser interface. The Unified Archive is preloaded with a pair of Glance images, one suitable for use with non-global zones and the other for kernel zones (solaris-kz branded zones). In order to use the Unified Archive method of installation, a suitable target is necessary. Detailed instructions for both methods of installation are included in the README file associated with the archive.
Using an Automated Installer (AI) server is the recommended way to install the OpenStack Unified Archive onto bare metal.
Once the installation is complete, you can proceed to reboot the system and answer some basic system configuration questions using the System Configuration Tool (assuming you didn't associate a system configuration profile as part of your AI server configuration). Once you have successfully created the zone configuration, you can install the kernel zone from the archive. As with the Automated Installer installation, you will then be prompted to use the System Configuration Tool for further system configuration. After the OpenStack installation is complete, you can log in to the OpenStack Horizon web-based dashboard to start evaluating the cloud environment and provision your first VM. When you log in as the cloud administrator, you will notice a main navigation menu on the left side, page content defined by the current selection of the left navigation bar, and account credentials in the top right corner. The Admin view allows you to see an overall view of the Nova instances and Cinder volumes in use within the cloud.
The other primary elements that the cloud administrator can view and edit concern projects (also known as tenants) and users. Under the Access & Security submenu, users can upload their own personal SSH public key to the Nova service. To create a new instance, a cloud user (the admin user or any multitenant user) simply needs to click the Instances submenu. In the Instances submenu screen, you can click the name of the instance to see general information as well to view the instance's console log. Note that by clicking the Volumes submenu, you can see the Cinder volumes that have been created. By clicking the Network Topology submenu of the Network menu, you can see a visual representation of the cloud network including all subnet segments, virtual routers, and active instances.
Now that you've installed OpenStack into a single-node environment, the common next step is to start creating a multinode environment.
The OpenStack services can be split across multiple physical nodes that define a logical grouping. A typical starting architecture would include a single controller node, a compute node, and a storage node.
Administrators will require more knowledge about OpenStack and how different services work together to achieve this.
David Comay is a senior principal software engineer who has been at Sun and Oracle since 1996 when he began working in the networking area specializing in routing protocols and IPv6. Leverage these informative resources to get valuable information about Brocade networking solutions, best practices, and much more. This Whole setup of  virtual machine is managed by a software or firmware, which is known as Hypervisor.
To put simply, cloud computing is the virtual world that eases the operations of businesses by storing the data, retrieving and enabling access from anywhere. You save a large part of capital expenditure- no need to invest on expensive software, hardware technological equipments etc. Of course, having your business information on a third-party platform does not guarantee security; while at the same time, it may not be insecure too.
Though security remains a concern, its ease of use and financial benefits make cloud computing more attractive and its benefits are greater in significance than disadvantages.

The company also offers complete internet marketing solutions including SEO, SMO, PPC marketing etc. OpenStack, the popular open source cloud computing platform, provides comprehensive self-service environments for sharing and managing compute, network, and storage resources through a centralized web-based portal. Oracle Solaris Zones offer significantly lower virtualization overhead making them a perfect fit for OpenStack compute resources. The Unified Archive feature of Oracle Solaris enables rapid application deployment in the cloud via a new archive format that enables portability between bare-metal systems and virtualized systems. Oracle Solaris makes updating OpenStack an easy and fail-proof process, updating a full cloud environment in less than twenty minutes. Taking advantage of Oracle Solaris network virtualization capabilities, applications can now drive their own behavior for prioritizing network traffic across the cloud. Nova provides the compute capability in a cloud environment, allowing self-service users to be able to create virtual environments from an allocated pool of resources. Glance provides image management services within OpenStack with support for the registration, discovery, and delivery of images that are used to install VMs created by Nova. Horizon is the web-based dashboard that allows administrators to manage compute, network, and storage resources in the data center and allocate those resources to multitenant users. Ironic provides bare-metal provisioning in an OpenStack cloud, as opposed to VMs that are handled by Nova. Heat provides application orchestration in the cloud, allowing administrators to describe multitier applications by defining a set of resources through a template.
Additional CPUs, memory, and disk space might be required, however, to support more than a trivial number of Nova instances. All of the essential OpenStack services are preinstalled and preconfigured to make setting up OpenStack on a single system easy. In addition, through the use of the new archiveadm(1M) command, new archives can be created from global, non-global, and kernel zones running Oracle Solaris 11 and then uploaded to the Glance repository for use with OpenStack. This is typically a bare-metal system on which the Unified Archive can be installed via the Automated Installer, or it can be a kernel zone. The following example creates an Oracle Solaris Kernel Zone using the SYSsolaris-kz template and allocates eight virtual CPUs and caps the memory at 12 GB.
The following example uses a disk size of 50 GB for this kernel zone to make sure there's enough space to create volumes for the VM instances. A cloud administrator account has been preconfigured and you can log in as admin with a password of secrete.
Within the left navigation menu, you can see that there are three main views: Project, Admin, and Identity. It also allows you to view and edit the Flavor definitions that define VM characteristics, such as the number of virtual CPUs, the amount of memory, and the disk space assigned to a VM.
Projects provide a mechanism to group and isolate ownership of virtual computing resources and users, while users are the persons or services that use those resources in the cloud. By default, the admin user is part of the demo project (as indicated in the account credentials in the top right of the screen). This public key is automatically placed in the root user's authorized_keys file in the new instance, which allows a user to log in to the instance remotely. Clicking Launch Instance on the right side produces a dialog box where the cloud user can specify the type of image (by default, non-global zone or kernel zone are the choices), the name of the new instance and, finally, the flavor of the instance. While single-node configurations are great for evaluating OpenStack, they are not suitable for a production environment where scalability and reliability are key goals.
Each cloud usually contains a single Horizon dashboard, a single Glance image repository, and a single Keystone identity service. The controller node hosts most of the shared OpenStack services that supply the API endpoints of OpenStack, scheduling services, and other shared functionality. He is responsible for a number of technology areas including OpenStack, the Oracle Solaris Image Packaging System, installation, and configuration management. Several small business owners find cloud extremely useful as it enables accessibility from anywhere. OpenStack has been integrated into all the core technology foundations of Oracle Solaris, allowing you to set up an enterprise private cloud infrastructure in minutes. Oracle Solaris Kernel Zones also provide independent kernel versions without compromise, allowing independent patch versions. Instant cloning in the cloud enables you to scale out and to reliably deal with disaster recovery emergencies. Through integration with the Oracle Solaris Image Packaging System (IPS), ZFS boot environments ensure quick rollback in case anything goes wrong, allowing administrators to quickly get back up and running.
The Elastic Virtual Switch (EVS) feature of Oracle Solaris provides a single point of control and enables the management of tenant networks through VLANs and VXLANs. A driver for Nova has been written to take advantage of Oracle Solaris non-global zones and kernel zones. Neutron creates and manages virtual networks across multiple physical nodes so that self-service users can create their own subnets that virtual machines (VMs) can connect to and communicate with.

Storage is presented to the guest VMs as virtualized block devices known as Cinder volumes.
Users can then create and destroy VMs in a self-service capacity, determine the networks on which those VMs communicate, and attach storage volumes to those VMs.
Swift provides redundant and scalable storage, with data replicated across distributed storage clusters. An Ironic driver has been written to take advantage of the Oracle Solaris Automated Installer, which handles multinode provisioning of Oracle Solaris 11 systems. As a result, a self-service user can execute this orchestration and have the appropriate compute, network, and storage deployed in the appropriate order. Although the Unified Archive can, in theory, be installed inside a non-global zone, the Nova compute virtualization in Oracle Solaris does not support nested non-global zones. In this case, however, you will be able to create only non-global zones as the VM compute environments. On Oracle Solaris, this is also where the brand of the underlying Oracle Solaris Zone is defined, such as solaris for non-global zones and solaris-kz for kernel zones.
Clicking through this view provides a set of options a cloud user can perform as a user under this project. The latter should match the zone type specified in the image type and the size chosen should reflect the requirements of the intended workload.
The time required for a new instance to be made available depends on a number of factors including the size of the images, the resources provided in the flavor definition that is chosen, and where OpenStack has placed the root file system of the new instance. In a multinode configuration, this volume might be remote from the instance using a protocol such as iSCSI or Fibre Channel. A cloud can, however, have any number of compute and storage instances, which is particularly useful when you want to take advantage of different hypervisor capabilities from different vendors or different back-end storage devices available in your data center.
He subsequently moved into the resource management area where he was a member of the original Oracle Solaris Zones project team. What you get is- have only what you want, enjoy a hassle-free working environment and stay more focused on the core functions. Check for what strategies and mechanisms these third-parties have in place in dealing with security issues.
Again what you need to do is check the vendor’s services and vulnerability, security policies and recovery systems they have.
Frame an all-embracing IT strategy that considers everything from the minute pitfalls to handy benefits of cloud technology to enjoy greater benefits.
Unified Archives in Oracle Solaris 11, combined with capabilities such as Immutable Zones for read-only virtualization and the new Oracle Solaris compliance framework, enable administrators to ensure end-to-end integrity and can significantly reduce the ongoing cost of compliance.
The networks are flexibly connected to virtualized environments that are created on the compute nodes. Neutron uses a highly extensible plug-in architecture, allowing complex network topologies to be created to support a cloud environment.
Finally, from a system provisioning perspective, this view also allows you to create virtual networks and routers for use by cloud users. When using the Oracle Solaris 11 OpenStack Unified Archive, the Images submenu of the Compute menu will reveal that the Glance service has been prepopulated with two images: one for instances based on non-global zones and the other for instances based on kernel zones.
Instances that are made of non-global zones have a volume assigned only if the volume is on a different node in the cloud.
He led that team after its initial project integration through the end of Oracle Solaris 10 and for several of the subsequent Oracle Solaris 10 update releases. Ranging from small businesses to mid-sized and large businesses, most businesses use cloud in some or the other way.
A driver for Neutron has been written to take advantage of the network virtualization features of Oracle Solaris 11 including the Elastic Virtual Switch that automatically creates the tenant networks across multiple physical nodes. Ephemeral volumes exist only for the lifetime of the VM instance, but will persist across reboots of the VM.
Unified Archives can be provisioned across both bare-metal and virtual systems, allowing for complete portability in an OpenStack environment. After driving the Oracle Solaris Modernization program and being the technical lead for the OpenSolaris binary releases as well as for Oracle Solaris 11, David is now the architect for the Oracle Solaris cloud strategy focusing initially on the integration of OpenStack with Oracle Solaris.
It becomes critical for organizations to understand the cloud’s importance, benefits and risks associated with it. Cinder drivers have been written to take advantage of the ZFS file system, allowing volumes to be created locally on compute nodes or served remotely via iSCSI or Fibre Channel.
