Its mission is to provide a flexible solution for both public and private clouds of any size, and for this matter two basic requirements are considered: clouds must be simple to implement and massively scalable. To meet these principles OpenStack is divided into different components that work together.
With these APIs, services can communicate with each other and also allows a service to be replaced by another with similar characteristics, only if the form of communication is respected. This is a simplified view of the architecture, assuming that all the services are used in the most standard configuration. Is a Django web application, a web framework for perfectionists ;) Those familiar with this framework will find Horizon code easy to understand. Web Server Gateway Interface WSGI is a specification for application servers and web servers to communicate with web applications.
The code is divided into reusable modules with logic, interaction with APIs, and presentation, to make customization in different sites easier. It also has a small database, SQLite3 by default, for some options, but most of the data are provided by the other services.
This notion is fundamental to understand this service since the administration of objects is it main objective. Both files and objects have metadata associated with the data they contain, but objects are characterized by their extended metadata.
Proxy server accepts incoming requests, like files to upload, modifications to metadata or container creation; it also serve files and container listing. Container servers manage a mapping of containers, folders, within the object store service. Also replication services run to provide consistency and availability across the cluster, audit and update. An image is a single file containing the complete contents and structure of a storage medium. Images are frequently used as a distribution medium for operating systems and instances (one particular execution time) of them. In other words, snapshots are running instances that can be obtained by creating a new image based on the current state of the disk of a particular instance. Every Keystone function has a pluggable backend which allows different ways to use the particular service.
Probably you will want to open the image in another tab … There are too many relatioships! I’m sure that many things remain pending – I am aware that the description of Keystone is pretty poor, and I will improve it! I understood the two-way arrows like both services can communicate with each other in a full-duplex style. About that, excellent work :) Your post gave me the tools needed to break the ice with OpenStack and get involved with the code in an easier way. And, please, add your suggestions here or by email, either way I’ll appreciate that a lot. In any case I will be subscribing in your rss feed and I’m hoping you write once more soon! We would appreciate it, it will help developer on this side, please excuse me IF have asked for more. Amazon Web Services (AWS) today announced the beta of their new storage gateway functionality that enables access of Amazon S3 (Simple Storage Services) from your different applications using an appliance installed in your data center site. With this beta launch, Amazon joins other startup vendors who are providing standalone gateway appliance products (e.g. Before going further, lets take a step back and address what for some may be a fundemental quesiton of what is a cloud storage gateway? Cloud services such as storage are accessed via some type of network, either the public Internet or a private connection.
Cloud access software and gateways or appliances are used for making cloud storage accessible to local applications. Some of the tools have added native support for one or more of the cloud services leveraging various applicaiotn programming interfaces (APIs), while other tools or applications rely on third-party access gateway appliances or a combination of native and appliances.
For example, I can use my Amazon S3 or Rackspace storage accounts using their web and other provided tools for basic functionality. Some traditional backup or archive tools have added direct or via third party support for accessing IaaS cloud storage services such as Amazon, Rack space, and others. The good news here is that Amazon is taking steps to make it easier for your existing applications and IT environments to use and leverage clouds for private and hybrid adoption models with both an Amazon branded and managed services, technology and associated tools.
This means leveraging your existing Amazon accounts to simplify procurement, management, ongoing billing as well as leveraging their infrastructure. Thus my first impression of AWS storage gateway at a high level view is good and interesting resulting in looking a bit deeper resulting in a second impression. Digging deeper and going through the various publicly available material (note can only comment or discuss on what is announced or publicly available) results in a second impression of wanting and needing to dig deeper based on some of caveats.
Pricing aside, which means as with any cloud or managed storage service, you will want to do a cost analysis model just as you would for procuring physical storage, look into the cost of monthly gateway fee along with its associated physical service running VMware ESXiconfiguration that you will need to supply. You will also need to assess the costs for using the S3 storage including space capacity charges, access and other fees as well as charges for doing snapshots or using other functionality.
Speaking of accessing the cloud, and cloud conversations, you will also want to keep in mind what your networking bandwidth service requirements will be to move data to Amazon that might not already be doing so. Another thing to consider with the AWS storage gateway is that it does not replace your local storage (that is unless you move your applications to Amazon EC2 and EBS), rather makes a copy of what every you save locally to a remote Amazon S3 storage pool. FWIW, I leverage a similar model where I use a service (Jungle Disk) where critical copies of my data get sent to that service which in turn places copies at Rack space (Jungledisks parent) and Amazon S3. By the way, a lesson learned here is that once my first copy is made which have data footprint reduction (DFR) techniques applied (e.g. Getting back to AWS storage gateway and my second impression is that at first it sounded great. However then I realized it only supports iSCSI and FWIW, nothing wrong with iSCSI, I like it and recommend using it where applicable, even though Im not using it. This leads up to my third impression the need to dig deeper into what AWS storage gateway can and cannot do for various environments. In addition to having an S3 account, you will need to acquire for a monthly fee the storage gateway appliance which is software installed into a VMware ESXi hypervisor virtual machine (VM). Note that the AWS storage gateway beta is optimized for block write sizes greater than 4Kbytes and warns that smaller IO sizes can cause overhead resulting in lost storage space. Initially I was excited about the idea of using a gateway that any of may systems could use my S3 storage pools with vs. Keep in mind that this solution or at least in its beta version DOES NOT replace your existing iSCSI based storage needs, instead it compliments what you already have. This announcement should reinvigorate some of the cloud appliance vendors as well as those who have embedded functionality to Amazon and other providers.
Keep bandwidth services and optimization in mind both for sending data as well as for when retrieving during a disaster or small file restore. In concept, the AWS storage gateway is not all that different than appliances that do snapshots and other local and remote data protection such as those from Actifio, EMC (Recoverpoint), Falconstor or dedicated gateways such as those from Nasuni among others. If the AWS were available with a NAS interface, I would probably be activating it this afternoon even with some of their other requirements and cost aside.

Im still formulating my fourth impression which is going to take some time, perhaps if I can get Amazon to help sell more of my books so that I can get some money to afford to test the entire solution leveraging my existing S3, EC2 and EBS accounts I might do so in the future, otherwise for now, will continue to research.

Ok, nuff said for now, I need to get back to some other things while thinking about this all some more.
Gateway in a virtualized network refers to an entity that allows network traffic to move back and forth between the virtual and the physical networks or between virtual networks operating on different set of technologies. OpenContrail is based on a standard-based control plane protocols and encapsulation mechanisms to operate. BGP MPLS VPN capable Data Center Gateway Router device allows for providing connectivity between the Enterprise customer’s virtual network assets residing in the Data Center and the existing physical PIP L3 VPN network using a standard Inter-AS VPN connectivity methodology. In this section, we will cover Junos configuration elements required to enable MX as a gateway router to a OpenContrail cloud environment. In this section, we will see configuration snippets for using Juniper a virtual SRX (firefly perimeter) as a Software gateway to OpenContrail Cloud. OpenContrail uses truly open standard based control and data plane signaling and hence can interoperate with any standard gateway to realize real complex use cases. The OpenStack summit in Paris not only marks the release of Juno to the public but also the 6 month mark since Red Hat acquired Inktank, the commercial company behind Ceph.
The Inktank Ceph Enterprise installer has also been modified to take pre-seeded configuration files from RHEL OpenStack Platform and use them to build out the storage cluster.
Looking ahead to the next 6 months, customers should expect many of the Ceph-specific features of Juno arriving in the next version of  Red Hat Enterprise Linux OpenStack Platform  6. Within the Ceph project, there is ongoing focus on improving performance in general which will be of particular interest to customers looking to back Trove databases with RBD storage. You can see a list of all of the Ceph related sessions on the OpenStack Summit website and developers are invited to attend the Ceph design session held at the summit. Red Hat’s goal to be the default vendor for the next generation of IT architectures is moving towards becoming a practical reality through its support and deep investment of OpenStack and Ceph. Spectra Logic announced on Wednesday certification of the Cyberduck open source client software tool with its BlackPearl Deep Storage Gateway. Spectra BlackPearl integration with Cyberduck open source tool enables unlimited choice in public cloud storage and private cloud local storage in one platform. Cyberduck is an open source client for FTP and SFTP, WebDAV, OpenStack Swift, and Amazon S3, available for Mac OS X and Windows (as of version 4.0) licensed under the GPL. The Cyberduck integration is cloud agnostic, allowing Spectra tape to directly connect to many public cloud providers, thus representing a key method of implementing certain tasks related to modern cloud computing. Cyberduck integration provides the ability to seamlessly move data between previously disparate storage platforms including local file systems, remote FTP systems, and a host of public cloud storage, including Amazon S3, Amazon Glacier, Google Cloud Storage and Drive, Microsoft Azure, Rackspace Cloudfiles and iRODS. Donna Loughlin Michaels, President & Founder, is known for her results-oriented PR programs, dedication to her clients and constant enthusiasm for technology.

Allows users to create their own networks and then link them to the devices of their choice. This is not a file system, is more like a container that can store files and retrieve them later.
Each object is assigned a unique identifier which allows a server or end user to retrieve the object without needing to know the physical location of the data.
But you may be right, it can be confusing… using two independent arrows seems clearer. It’s a great document that explains things both in detail and from a high-level overview. AWS API Gateway doit aussi composer avec Microsoft API Management, qui repose sur la technologie da€™Apiphany, racheté en 2013.
The gateways, as well as enabling cloud access, provide replication, snapshots, and other storage services functionality. Another option for accessing cloud resources is to use tools (Figure 2) supplied by the service provider, which may be their own, from a third-party partner, or open source, as well as using their APIs to customize your own tools. However, for doing backups and restores, I use the tools provided by the service provider, which then deal with two different cloud storage services.
VMs can be moved to a cloud service using file transfer tools or upload capabilities of the provider.
Now granted and in fairness to Amazon, this is of course a beta release and hence while on first impression it can be easy to miss the notice that it is in fact a beta so keep in mind things can and hopefully will change. Chances are that if you are an average sized SMB, you have a physical machine (PM) laying around that you can throw a copy of ESXi on to if you dont already have room for some more VMs on an existing one. Again these are not unique to Amazon or their cloud gateway and should be best practices for any service or solution that you are considering. This can be good for high availability (HA), business continuance (BC), disaster recovery (DR) and compliance among other data management needs.
This can be gotten around by using multiple gateways however the increased complexity balanced to the benefit the functionality is something to consider. I can see where it can be a fit for some environments while for others at least in its beta version will be a non starter.
This is a consideration for systems that have not yet changed your file systems and volumes to use the larger allocation sizes.
As a result of this approach, industry standard routing platforms can be used as gateways to the virtual networks differentiating OpenContrail from some of the available solutions.
The Data Center edge router will act in an Inter-AS VPN ASBR role bridging the ASN used in the Contrail virtual-network overlay topology to the ASN used in the service provider L3 VPN core. For each destination network learnt over BGP, there is a dynamic GRE tunnel automatically established to the Compute node.
I was just trying to understand configuration for route-leaking between Contrail (VRF) and Internet (Global routing table), would it be possible to share reference diagram to understand configuration much better ? The acquisition not only underscored Red Hat’s commitment to use open source to disrupt the storage market, as it did in the operating system market with Linux, but also its investment in OpenStack where Ceph is a market leading scale-out storage platform, especially for block.
The new Red Hat Enterprise Linux OpenStack Platform installer now handles configuration of the Ceph components on the controller and compute side, from installing the packages to configuring Cinder, Glance and Nova to creating all the necessary authentication keys. With some of the Ceph services architected to run co-resident on the controller nodes, the number of physical nodes needed has been reduced without sacrificing security of performance. With the largest number of committers to both OpenStack Juno and Ceph, Red Hat are the only vendor able to deliver full top to bottom support for the combined stack with a “single throat to choke” model. In particular, full support for ephemeral volumes backed by the Ceph block device (RBD) means that Ceph can handle all block storage for both Nova and Cinder, opening the possibility for ‘diskless’ compute nodes and near-instantaneous booting of new VMs.
Finally, during the Kilo cycle, Red Hat’s Ceph and OpenStack will be focusing on blueprint work that extends the multi-site and disaster recovery options. The week before the summit the Ceph project will also be running its regular Ceph Design Summit for the upcoming Hammer release. As ever, we welcome feedback on where customers would like to see deeper integration and look forward to seeing everyone at the upcoming Paris summit.

The Cyberduck universal file and object storage management tool combined with Spectra BlackPearl enables fast file transfers between primary storage, local tape and disk-based private clouds, or to any public cloud provider.

Cyberduck is written in Java and C# using the Cocoa user interface framework on OS X and Windows Forms on Windows.
In the same interface, drag and drop between tape and cloud, cloud and cloud, the options are endless.
Using Spectra’s private cloud ecosystem means that infrequently accessed data can be archived to disk or tape for pennies per gigabyte, reducing the storage and recall fees associated with a pure public cloud strategy, with a simplified and familiar Cyberduck interface. Both C-level management and venture capitalists have praised her innovative public relations programs that have strengthened brands, catapulted companies to market leadership, secured loyal customer following and driven revenue.
This approach is useful for automating and streamlining data storage in cloud computing environments. The customer does not know where his car will be parked or how many times an attendant might move the car while the customer is dining. Having said that, I’ll try to make the Grizzly set of pictures more clear and maybe using the arrows as you suggest might be a good idea. For example, some services can be accessed using a standard Web browser, while others must plug-in or add-on modules.
Cloud access gateways or server-based software include tools from BAE, Citrix, Gladinet, Mezeo, Nasuni, Openstack, Twinstrata and Zadara among others. The tool presents an interface for defining what to back up, protect, and restore, as well as enabling shared (public or private) storage devices and network drives.
For example, a VM such as a VMDK or VHD  is prepared locally in your environment and then uploaded to a cloud provider for execution. For example, if you subscribe to Amazon S3, storage is allocated as objects and various tools are used to use or utilize. Amazon makes it easy by the way to see their base pricingfor different tiers of availability, geographic locations and optional fees. However in your cost model you also need to keep in mind that you are not replacing your local storage, you are adding to it via the cloud which should be seen as complimenting and enhancing your private now to be hybrid environment. I also have local backup copies as well as master gold disaster copy stored in a secure offsite location. However subsequent restores of those large files or volumes also takes longer to retrieve from the cloud vs. Granted for those environments that already are using iSCSI for your servers that will be using AWS storage gateway, then this is a non issue while for others it is a consideration including cost (time) to factor in to prepare your environment for using the ability.
In the meantime, do your homework, look around at other options which ironically by having Amazon launching a gateway service may reinvigorate the market place of some of the standalone or embedded cloud gateway solution providers.
Likewise I was excited by the idea of having an easy to install and use gateway that would allow me to grow in a cost effective way. In this blog, we will see various approaches in setting up and using a Gateway to a OpenContrail Cloud.
With the Ceph client-side components now directly available in RHEL OpenStack Platform, much of what was a manual effort has now been transformed & automated. A second phase of integration work around the installation process is also starting, with the goal of creating a single, unified installation workflow for both RHEL OpenStack Platform and Inktank Ceph Enterprise that will allow for flexible topologies and “touch of a button” scale-out. Here, the ongoing work around RBD Mirroring and the volume replication capabilities in OpenStack Cinder are high on the list – though extending Glance to handle legacy image types and prepare them for RBD will also receive attention.
BlackPearl uses internal management policies for different storage devices, enabling the system to write data to different tape libraries, tape partitions, and nearline and online disk. The industry veteran’s monikers include the “PR She Devil” of Silicon Valley and beyond as well as Donna “Powers,” having ushered in 5 personal IPOs and taking hundreds of startups to The Street and Headline News. I like to feel the music flowing on my face, I like good books and romantic, action,cartoon movies. I will use this when explaining to different people how things relate and break down as it illustrates that easily. In addition to gateway vendors, there are also those with cloud access added to their software tools such as (e.g. Some cloud services may need downloading an application, agent, or other tool for accessing the cloud service or resources, while others give an on-site or on-premises appliance or gateway. In addition to cloud gateway appliances or cloud points of presence (cpops), access to public services is also supported via various software tools. In addition to providing an interface (Figure 2), the tool also speaks specific API and protocols of the different services, including PUT (create or update a container), POST (update header or Meta data), LIST (retrieve information), HEAD (metadata information access), GET (retrieve data from a container), and DELETE (remove container) functions. Cloud services may give an access program or utility that allows you to configure when, where, and how data will be protected, similar to other backup or archive tools. The cloud access software or appliance understands how to communicate with the IaaS  storage APIs and abstracts those from how they are used. In addition to sending data to S3, the integrated functionality with other AWS services should make it easier to integrated with Elastic Cloud Compute (EC2) and Elastic Block storage (EBS) capabilities including snapshotsfor data protection. The idea is that when needed, I can get a good copy restored from my cloud providers quickly regardless of where I am if the local copy is not good. You will also need iSCSI initiators on either Windows server 2008, Windows 7 or Red Hat Enterprise Linux. In particular, we will focus on three different gateways options which will also cover a vendor agnostic solution and a virtualized gateway as an option. In addition the RHEL OpenStack Platform installer also takes responsibility for the configuration of the storage cluster network topology and will boot and configure the hosts that will be used by the Ceph storage cluster. This management feature, called Advanced Bucket Management (ABM), allows BlackPearl to control where and how data is written.
The user interacts with the user interface, including file transfer by drag and drop and desktop notifications, and is also able to open some files in external text editors.
Jungle Disk that access both Rack space and Amazon S3 along with Commvault Simpana Cloud connector among others). Access software tools or gateways, in addition to translating or mapping between cloud APIs, formats your applications including security with encryption, bandwidth optimization, and data footprint reduction such as compression and de-duplication. On the other hand, experience has already demonstrated that without sufficient network bandwidth services, if I need to bring back 100s of GBytes or TBytes of data quickly, Im going to be better off bring back onsite my master gold copy, then applying fewer, smaller updates from the cloud service. There are also vendors that have joined cloud access gateways as part of their storage systems such as TwinStrata among others. The importance of mentioning the above example is that when you look at some cloud storage services providers, you will see mention of PUT, POST, LIST, HEAD, GET, and DELETE operations as well as services such as capacity and availability.
Other functionality include reporting, management tools that support various interfaces, protocols and standards including SNMP or SNIA, Storage Management Initiative Specification (SMIS), and Cloud Data Management Initiative (CDMI).
Even EMC (and here) has gotten into the game adding qualified cloud access support to some of their products. Some services will include an unlimited number of operations, while others will have fees for doing updates, listing, or retrieving your data in addition to  basic storage fees. However also keep in mind that if a disaster occurs, will your local appliance be affected and its cache rendered useless.
By being aware of cloud primitive functions such as PUT or POST and GET or LIST, you can have a better idea of what they are used for as well as how they play into evaluating different services, pricing, and services plans.
