Swift Architecture is distributed in nature, and it also prevent the single point of failure and can be scaled horizontally. Elastic in nature as storage can be increased or decreased.There are following benefits of using Swift as object storage solution: Swift is the Object storage service provided by Open Stack and was developed by joint efforts of NASA and Rack Space. These type of storage are not suitable for high performance requirement or the system that frequently changes data in database.And the data cannot be accessed by file protocol such as BFS, SMB or CIFS.
Object Storage are accessed using an API called REST or SOAP.In the object Storage, Data are stored as binary large objects (blobs) with multiple replicas on Object Storage servers.By this type of storage, even though nodes fails, data are not lost and these type of storage can be scaled infinitely. In object storage, data is stored in from of objects via RESTful HTTP API. Persistent storage is divided in to three options:
This type of storage means, even though the VM is powered off the storage and its data will be available. As the name suggests, anything stored will be lost as soon as VM is terminated. In working as soon as any VM is booted, glance image downloaded on compute node and this image is used as first disk for nova instance which further provides ephemeral storage. This is non-persistence storage, in which as soon as VM is terminated, it loses the associated disk. Thera are two types of storage option mostly available to provide storage solution to compute nodes and further to instances. It store and retrieve virtual machine disk images.Images can be used as a template in setting up a new server, usually images are stored in swift object service.Posted on (0) OpenStack Block Object and File Share Openstack storage Storage Option: If client again request the same image then gives directly from the cache. In the above diagram when client request an image then glance-api service access storage network (br-storage) and pulls it into cache. It is Secure, scalable and reliable online storage Object storage is very suitable as low-cost storage, for example for virtual machine images, snapshots, photos, video and backups.This is ideal for static data. Swift stores an object’s metadata with the object itself. In this storage size is determined by instance and image used in Open Stack.The size of ephemeral storage is determined by the flavour of the instance and the image used. It means this is use for short period of time. we can attached a single instance at a time.Īn ephemeral storage is deleted when an instance is itself deleted by the cloud user or admin It is used when VM are short-lived and data does not need to persist beyond the life of a given VM. In this storage mechanism when you delete or relaunch an instance then you can keep data in cinder block storage and re-attached into new instance.We can extend a cinder volume if need to grow the capacity of disk used by a cloud instance we can use a volume as an external hard drive and it’s attach it to an instance. Block storage manually created by the users. This is most important and popular storage option in Open Stack. It handle the core cloud-computing services of compute, networking, storage, identity, and image services It offers unlimited storage pools and supports block-IO from a variety of vendors, as well as object file storage. Open Stack is an open source platform that uses pooled virtual resources to build and manage private and public clouds. Reading Time: 2 minutes What is Open Stack ?
