OpenStack Object Storage (swift) is used for redundant, scalable datastorage using clusters of standardized servers to store petabytes ofaccessible data. It is a long-term storage system for large amounts ofstatic data which can be retrieved and updated. Object Storage uses adistributed architecturewith no central point of control, providing greater scalability,redundancy, and permanence. Objects are written to multiple hardwaredevices, with the OpenStack software responsible for ensuring datareplication and integrity across the cluster. Storage clusters scalehorizontally by adding new nodes. Should a node fail, OpenStack works toreplicate its content from other active nodes. Because OpenStack usessoftware logic to ensure data replication and distribution acrossdifferent devices, inexpensive commodity hard drives and servers can beused in lieu of more expensive equipment.
I would like to implement a cloud storage service with the same interface of OpenStack Swift or Amazon S3. In other words, my cloud storage service should expose the same API of the above-mentioned services but with a custom implementation. This way, a client will be able to interoperate with my service without changing its implementation.
I would recommend using Swift (Openstack object store ) which also supports S3 APITake a look at the following link: -object-storage/admin/content/configuring-openstack-object-storage-with-s3_api.html
The software comes with a Free 10TB license, so pretty much it is free up to 10TB of managed storage, after that it is reasonably priced. You can install the software in any x86 hardware running Linux.
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.
The authors have explained complex concepts related to cloud storage and OpenStack Swift in a very simple and lucid manner. The book contains 8 detailed chapters that will help you learn about the fundamentals of cloud storage using OpenStack Swift. While the book delves deep into OpenStack Swift Architecture, it also provides some interesting design examples and use cases for Enterprises looking to implement OpenStack Swift.
In the TechDocs architecture you have the option to choosewhere you want to store the Generated static files which TechDocs uses to renderdocumentation. In both the \"Basic\" and \"Recommended\" setup, you can add cloudstorage providers like Google GCS, Amazon AWS S3, etc. By default, TechDocs usesthe local filesystem of the techdocs-backend plugin in the \"Basic\" setup. Andin the recommended setup, having one of the cloud storage is a prerequisite.Read more on the TechDocs Architecture documentation page.
4c. Authentication using an assumed role Users with multiple AWS accountsmay want to use a role for S3 storage that is in a different AWS account. Usingthe roleArn parameter as seen below, you can instruct the TechDocs publisherto assume a role before accessing S3.
The storage blob client will automatically use the environment variableAZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET to authenticate withAzure Blob Storage.Steps to create the service where the variables can be retrieved from.
To get credentials, access the Azure Portal and go to \"Settings > Access Keys\",and get your Storage account name and Primary Key. -us/rest/api/storageservices/authorize-with-shared-keyfor more details.
The proxy server exposes public API and serves requests to storage entities. For each request, the proxy server looks up the location of the account, container, and object using the ring. Once it has their location, it routes the request accordingly. Objects are streamed between the proxy server and client directly and no buffering is enabled (to make it even more clear: even though it has \"proxy\" in the name, the \"proxy\" server does not do any \"proxying\" to speak of, such as you might be familiar with from http).
Ceph is a distributed network storage with distributed metadata management and POSIX semantics. The Ceph object store can be accessed with a number of clients, including a dedicated cmdline tool, FUSE, and Amazon S3 clients (through a compatibility layer, called \"S3 Gateway\"). Ceph is highly modular - different sets of features are provided by different components which one can mix and match. Specifically, for object store accessible via s3 API it is enough to run three of them: object server, monitori server, RADOS gateway.
ceph-osd is the storage daemon that runs on every storage node (object server) in the Ceph cluster. ceph-osd contacts ceph-mon for cluster membership. Its main goal is to service object read/write/etc. requests from clients, It also peers with other ceph-osds for data replication. The data model is fairly simple at this level. There are multiple named pools, and within each pool there are named objects, in a flat namespace (no directories). Each object has both data and metadata. The data for an object is a single, potentially big, series of bytes. The metadata is an unordered set of key-value pairs. Ceph filesystem uses metadata to store file owner, etc. Underneath, ceph-osd stores the data on a local filesystem. We recommend Btrfs, but any POSIX filesystem that has extended attributes should work.
OpenStack is a free, open standard cloud computing platform. It is mostly deployed as infrastructure-as-a-service (IaaS) in both public and private clouds where virtual servers and other resources are made available to users. The software platform consists of interrelated components that control diverse, multi-vendor hardware pools of processing, storage, and networking resources throughout a data center. Users manage it either through a web-based dashboard, through command-line tools, or through RESTful web services.
The project intended to help organizations offer cloud-computing services running on standard hardware. The community's first official release, code-named Austin, appeared three months later on 21 October 2010 (2010-10-21), with plans to release regular updates of the software every few months. The early code came from NASA's Nebula platform as well as from Rackspace's Cloud Files platform. The cloud stack and open stack modules were merged and released as open source by the NASA Nebula team in concert with Rackspace.
In 2011, developers of the Ubuntu Linux distribution adopted OpenStack with an unsupported technology preview of the OpenStack \"Bexar\" release for Ubuntu 11.04 \"Natty Narwhal\". Ubuntu's sponsor Canonical then introduced full support for OpenStack clouds, starting with OpenStack's Cactus release.
In 2012 NASA withdrew from OpenStack as an active contributor, and instead made the strategic decision to use Amazon Web Services for cloud-based services. In July 2013, NASA released an internal audit citing lack of technical progress and other factors as the agency's primary reason for dropping out as an active developer of the project and instead focus on the use of public clouds. This report is contradicted in part by remarks made by Ames Research Center CIO, Ray O'Brien.
Keystone is an OpenStack service that provides API client authentication, service discovery, and distributed multi-tenant authorization by implementing OpenStack's Identity API. It is the common authentication system across the cloud operating system. Keystone can integrate with directory services like LDAP. It supports standard username and password credentials, token-based systems and AWS-style (i.e. Amazon Web Services) logins. The OpenStack keystone service catalog allows API clients to dynamically discover and navigate to cloud services.
In August 2009, Rackspace started the development of the precursor to OpenStack Object Storage, as a complete replacement for the Cloud Files product. The initial development team consisted of nine developers. SwiftStack, an object storage software company, is currently the leading developer for Swift with significant contributions from Intel, Red Hat, NTT, HP, IBM, and more.
Zaqar is a multi-tenant cloud messaging service for Web developers. 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.
OpenStack does not strive for compatibility with other clouds' APIs. However, there is some amount of compatibility driven by various members of the OpenStack community for whom such things are important.
An OpenStack Appliance is the name given to software that can support the OpenStack cloud computing platform on either physical devices such as servers or virtual machines or a combination of the two. Typically a software appliance is a set of software capabilities that canfunction without an operating system. Thus, they must contain enough of the essential underlying operating system components to work. Therefore, a strict definition might be: an application that is designed to offer OpenStack capability without the necessity of an underlying operating system. However, applying this strict definition may not be helpful, as there is not really a clear distinction between an appliance and a distribution. It could be argued that the term appliance is something of a misnomer because OpenStack itself is referred to as a cloud operating system so using the term OpenStack appliance could be a misnomer if one is being pedantic. 59ce067264
