Advantages of Cloud Storage
According to a report from University of Berkeley, some of the key characteristics of Cloud Computing are “the illusion of infinite computing resources, the elimination of an up-front commitment by cloud users, and the ability to use as per demand” [7]. According to [8], the goal of cloud computing is to scale the resources up or down through APIs according to the user demand without much interaction from the user. Cloud computing is a blend of different technologies that matured at different pace and in different environment [6]. It was not designed as a whole, but all those technologies have come together to create a technical ecosystem for cloud computing [6]. Specifically cloud computing offers many advantages,

With cloud storage system, your files can be shared instantly with anyone you want to regardless of their location.
8. Disaster Recovery
Cloud Storage can be a better emergency backup plan in case of an emergency for businesses. A second copy of important files can be uploaded. These files are stored in remote locations and can be accessed through internet. In the event of data loss, you will have backup of all files and can be restored with zero downtime.
Although there are concerns over cloud storage, many business organizations believe that the benefits of Cloud Storage systems outweigh the drawbacks and risks. The above mentioned advantages are few of the intriguing benefits to businesses. Cloud storage can simplify IT management, improves the user experience and allows employees to work from different locations. This eases IT logistics by simplifying sharing and collaboration among IT staff.

Unifying themes
In this section we discuss various unifying themes that underlies the Cloud Storage systems discussed in this paper. According to [2], the major unifying themes are voluminous data, commodity hardware, distributed data, expected failures, tune for access by applications, optimize for dominant usage, tradeoff between consistency and
‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.
Hadoop [8] is an open source implementation of MapReduce programming model which runs in a distributed environment. Hadoop consists of two core components namely Hadoop Distributed File System (HDFS) and the MapReduce programming with the job management framework. HDFS and MapReduce both follow the master-slave architecture. A Hadoop program (client) submits a job to the MapReduce framework through the jobtracker which is running on the master node. The jobtracker assigns the tasks to the tasktrackers running on many slave nodes or on a cluster of machines.
S-CSP: Storage provider is nothing but kind of an entity which makes available storage services of data inside a public cloud. S-CSP offers outsourcing data services and then it stores that data in support of a users of the data. To trim down the cost of storage, the Service Providers eradicates the storing of an unneeded data by using Deduplication technique or methods whereas it also maintains only distinctive form of data rather keeping all the files having similar content. Users:
7.7.1 Data Owners 1. One whose going to access files, one who owns file, who requires his data to be secure. 2. Data owners are responsible for encrypting the data by generating private key. MMCOE, Department of Computer Engineering, 2015-2016 26 Regeneration of code based cloud storage 3.
Network monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system called Marple was created by researchers at MIT, Cisco Systems, and Barefoot Networks(Hardesty). Marple involves a programming language the allows network operators to specify a wide range of network-monitoring tasks and a small set of simple circuit elements that can execute any function specified in the language.
FTI leverages native storage and multiple replications and erasures techniques to supply many levels of dependability and performance. FTI provides application-level check inform that enables users to pick out that knowledge must be protected, so as to enhance potency and avoid house, time and energy waste. Figure It offers an on the spot knowledge interface so users don 't have to be compelled to wear down files and/or directory names. All data is managed by FTI in a very clear fashion for the user.
I addressed this question in two parts, first what would I do from technology perspective and then format and key items that will be part of my Disaster Recovery (DR) Plan Like I mentioned earlier, in the next 10-15 years with cloud computing all my information will be on virtual servers. Developing a virtual backup strategy depends on a few factors such as the service levels required and the suitability of existing backup products. To start with virtual servers can’t be backed up like physical ones, with an agent per virtual machine, because of the I/O and CPU bottlenecks created. Virtual machines are much harder to track for backup purposes. Previously a physical server hosted an application and that one-to-one relationship was almost never broken.
Thanks to its flash storage which uses solid state technology, which means there are no moving parts. Without any moving mechanical parts, flash storage is more reliable, durable and quiet than traditional hard drives. And, it takes up much less space than a traditional hard drive too. That creates room
Prevalent storage choices include the S3 (Amazon Simple Storage Service), EBS (Elastic Block Store) and Amazon CloudFront. Amazon Simple Storage Service offers Web Service based storage and it is a totally redundant storage offering that can process any amount of data at anytime and anywhere on the Web. It can be used for backup, record and calamity recovery, and content storage, allocation and data analysis storage. S3 is current as part of the free Amazon Elastic Compute Cloud (EC2) tier service for 5GB of storage, 20,000 Get Needs or 5,000 Put Needs per month.
Backing up data regularly is essential to prevent the loss of data in case of disasters such as power outage, flood or fire. Without a backup file it would be impossible to try and recreate files that were
CO4507 Digital Forensic Investigation Introduction Nowadays digital devices are everywhere in our life’s helping peoples in many sectors and providing possibilities to them. By pronounce the term “digital devices” the majority of the peoples thinking the computers, smart phones, tablets and the cloud applications. Now the digital devices are important not only in our work environment, or for entertainment and educational reasons, but are important because we can use them as digital evidence. Any kind of technology that processes information can be used in a criminal way vise versa can be used as digital evidence in the court.
Console Window Web Class library Control library Smart Device Console: Server terminals: Many servers use is controlled exclusively through console programs. siege: Siege is an http/https stress load tester used to test different web servers through terminal interface program. Abcde: Abcde is a CD encoder program that will rip or burn different cds to and from your computer.
Additionally, risks associated with outage or lock-in of a single CSP are reduced. This provides a high level of availability and reliability for the service. Observation_2: CSUs can use different types of devices, for example, a laptop or a mobile device to access the storage service. A CSP uses notification servers to synchronise the CSUs’ files between the devices. Observation_3: As seen in the model, each CSP uses a database server to store and manage metadata.
All large and some small business have the backup system. Also, home user are also backup as well, although most do not. Audit
How would the platforms interact with the different stakeholders? Accordin to Freeman (1984), stakeholders are anyone that can influence or be influenced by the company’s actions. And there are two types of stakeholders, including the primary and seconday stakeholders ( Clarkson, 1995). For Starbucks, its major stakeholders include employees, customers, suppliers and stockholders. Starbucks’ performances and business strategies could also affect the general public and the society.
