Cloud Storage Reliability for Big Data Applications: A State of the Art Survey Rekha Nachiappan a, Bahman Javadi , Rodrigo Calherios , Kenan Matawie a aSchool of Computing, Engineering and Mathematics, Western Sydney University, Australia Abstract Cloud storage systems are now mature enough to handle a massive volume of In a… Hard disk devices also seem to have a history of not working properly. It can be integrated into data protection solutions to optimize them. There are multiple reasons to use cloud storage services. Posted by: Jacob on March 8, 2015 Under: Cloud Storage |. There are many different geographically distributed cloud clusters in a cloud environment. Cloud storage has proved its merits and advantage over other types of storage devices in all departments. Hard disk with its incompatibility is a major drawback for a person. Hard disks would be compatible only with a particular OS and it would be impossible for a user to manage the hard disk every time. File sharing service is an exciting feature utilized mostly by expats and business professionals to communicate with their closed ones, clients, colleagues etc. All rights reserved. He received his MS and PhD degrees in Computer Engineering from the Amirkabir University of Technology in 2001 and 2007, respectively. Improving fault tolerance in cloud storage systems for Big Data applications is a significant challenge. Business meetings, conferences, client communications etc. (Mathematics) degree from Alagappa University, India in 2006, Master of Computer Applications degree from Madurai Kamaraj University, India, in 2009 and Master of Philosophy from Prist University, India in 2012. Research conducted on the number of hard disk drives that get damaged every year without showing any warning signs indicate that around 5 to 8% of the total number of hard disks manufactured in the world seem to have a very less lifetime. Agility — Can the cloud storage support unanticipated changes? Will the Software Slow Down My Computer During Backup? External hard disks are easier to carry when compared to the hard disks of PCs. At present, there is no possible way to syncing smartphones with hard disks. Maybe your local hard drives are running low on disk space, in which case you can use the cloud as extra storage. Cloud Storage Risks Vs Cloud Storage Benefits. From 2008 to 2010, he was a Postdoctoral Fellow at the INRIA Rhone-Alpes, France. File sharing feature offered by cloud would enable users to access their stored data from multiple locations using multiple devices. Dr Kenan M. Matawie is a Senior Lecturer of Statistics in the School of Computing, Engineering and Mathematics at Western Sydney University-Australia. Explore the shared responsibilities that customers and Azure have in designing and operating resilient apps and systems. An enterprise-level object storage solution for all your data. Hard disk storage devices are vulnerable and are not reliable in quite a lot of ways. Hard disk storage service would not be as efficient as that of a cloud in this case. Safety Kenan has a PhD from University of New South Wales, Australia. Security, Reliability and Availability Issues with Cloud Computing Cloud Computing is a technology in which different users are able to access computing facilities from a single multi-provider who normally has the requisite infrastructure and or software and vends them out for a fee. However, failures are inevitable in cloud storage systems as they are composed of large scale hardware components. Cloud storage reliability for Big Data applications: A state of the art survey @article{Nachiappan2017CloudSR, title={Cloud storage reliability for Big Data applications: A state of the art survey}, author={R. Nachiappan and B. Javadi and R. … Replication and Erasure coding are the most important data reliability techniques employed in cloud storage systems. would affect hard disks and cause damage to the data stored by the user. Replication and Erasure coding are the most important data reliability techniques employed in cloud storage systems. Customers can forecast cloud storage spend easily, without requiring pricing formulas to predict their cloud spend. © 2017 Elsevier Ltd. All rights reserved. Cloud storage reliability for Big Data applications: A state of the art survey. Universal access Hard disk storage devices are vulnerable and are not reliable in quite a lot of ways. Cloud storage maybe not be as fast as external drives but it does take care of a fundamental problem external HDDs can’t fix: reliability. When files and data are sent to the cloud, they are actually being sent to a server that is connected to the internet. We use cookies to help provide and enhance our service and tailor content and ads. When it comes to reliability, here are some things to consider when choosing on-prem vs. cloud storage: On-premises Some businesses like the idea of on-premises because it does not require an internet connection for onsite employees to access storage, making it fully available without the need for a good connection. Hard disk drives can be used by the users only when they have all the supporting devices in place. Unlike other Cloud Storage storage classes, Archive Storage has no availability SLA, though the typical availability is comparable to Nearline Storage and Coldline Storage. Cloud storage servers are not affected by any of these instances and it is possible to experience complete data safety with the help of cloud storage servers. I have no reason to question the cloud saves reliability just slightly concerned having spend soo many hours on a save. ... Google BigQuery Service, and the standard storage class of Google Cloud Storage have a 99.9% SLA except for the Durable Reduced Availability Storage class of Google Cloud Storage which has a 99% SLA. He has received numerous Best Paper Awards at IEEE/ACM conferences for his research papers. Physical damage, virus attacks, overwriting, etc. He is co-founder of the Failure Trace Archive, which serves as a public repository of failure traces and algorithms for distributed systems. Improve the reliability of your workloads by implementing high availability, disaster recovery, backup, and monitoring on the trusted Azure cloud. Cloud, on the other hand, can be accessed from smartphones and tablets. Individuals who have stored their data in multiple hard disks would find that they need to carry all their hard disks along with them every time in order to access the contents stored in the device. She is currently working toward the Ph.D. degree in the School of Computing, Engineering and Mathematics, University of Western Sydney, Australia. Without a proper power supply, users would not be able to run the device and access the files stored in them. Readers would now know how cloud is more reliable and efficient when compared to hard disk drives. However, failures are inevitable in cloud storage systems as they are composed of large scale hardware components. Rodrigo N. Calheiros is a Lecturer in the School of Computing, Engineering and Mathematics, Western Sydney University, Australia. Users would be able to access their confidential files right from their smartphones and tablets during emergency situations. Required fields are marked *.
