Spark provides programmers with an application programming interface centered on a data structure called the resilient distributed dataset (RDD), a read-only multiset of data items distributed over a cluster of machines, that is maintained in a fault-tolerant way. It was developed in response to limitations in the MapReduce cluster computing paradigm, which forces a particular linear dataflowstructure on distributed programs: MapReduce programs read input data from disk, map a function across the data, reduce the results of the map, and store reduction results on disk. Spark's RDDs function as a working set for distributed programs that offers a (deliberately) restricted form of distributed shared memory
Zadara is a powerful enterprise-level storage solution whose design enables it to handle every aspect of a user’s data storage needs. It can be deployed in any location, using any protocol, and storing any data type that an organization requires. With Zadara, organizations can do everything that they were able to do with more traditional systems in a cheaper and more efficient way.
Zadara Benefits
Some of the ways that organizations can benefit by choosing to deploy Zadara include:
-
Security. Zadara is built with data security in mind. All of a user’s data is heavily encrypted by Zadara’s software so that it is safe both while it is in storage and while it is being transferred somewhere else. It comes with role-based access controls that prevent a user’s data from being seen by those who lack the proper level of authorization. It also comes with dual-factor authentication and other similar methods of identity management.
-
Reduced costs. While Zadara offers enterprise-level storage capabilities, the costs associated with utilizing it are far less than those of similar solutions. Some of the resources that it offers are totally free of cost. The model that it utilizes is a pay-as-you-go model. Organizations only pay for the resources that they use and nothing more. Users are not required to sign up for any particular period of time. They are in complete and total control of what they spend on the solution.
-
Storage efficiency. Zadara ensures that users are able to store their data in the most efficient way possible. It takes a number of approaches that prevent insufficient data storage. These approaches are:
1. Thin-provision volumes. This method only allows actually written data to be counted toward the storage capacity that is consumed.
2. Pattern removal. Zadara searches a user’s stored data for repetitive binary sequences. Once it identifies the repetitive binary sequences, it deletes them.
3. Inline deduplication (all-flash only). This method ensures that Zadara only stores unique data blocks in its system.
4. Inline compression. Zadara takes data that is stored in its system and compresses it. This keeps larger blocks of data from taking up too much room.
Zadara Features
-
Centralized management. Zadara comes with a centralized dashboard that enables organizations to monitor and control their storage operations from a single location.
-
Remote mirroring. This feature enables users to replicate data in two remote locations at the same time. This makes it easy for data to be recovered in the event of an unexpected loss. It also aids remote teams in their collaboration efforts by giving them access to the same data at the same time.
Reviews from Real Users
Zadara is a highly effective solution that stands out when compared to many of its competitors. Two major advantages it offers are its extensive suite of cloud solution integrations and its object storage capability.
Steve H., the chief technology officer at Pratum, writes, “One of the most valuable features is its integration with other cloud solutions. We have a presence within Amazon EC2 and we leverage computer instances there. Being able to integrate with computing, both locally within Zadara, as well as with other cloud vendors such as Amazon, is very helpful, while also being able to maintain extremely low latency between those connections.”
Mauro R., the CEO of Momit SRL, says, “The object storage feature is wonderful. With traditional storage, you have a cost per gigabyte that is extremely high or related to the number of disks. With Zadara Storage Cloud, you have a cost per gigabyte that you can cut and tailor to your needs independent of the number or size of the disks.”
