However, there is more involved in this that would be provided by a static storage repository. The benefits of cloud based storage are apparent when its costs are compared to those of implementing and maintaining in-house archival storage, and even more so when organisations must adhere to substantial data retention policies. In house archives are expensive and resource hungry in terms of both IT human resources and hardware.  As archives must be retained in the long term it is often necessary to migrate them to new hardware, and it is generally essential to maintain long term hardware and software support contracts. Some organisations opt for a half-way house, a kind of a hybrid cloud archive where some of the data that might need to be available for high speed access is retained in house, with the email which has a lower level of priority being moved to the cloud-based archive. As an illustration of how cloud archiving works, we will consider the SaaS company Mimecast. Every file is indexed before it is stored in the archive, which permits administrators and end users to implement rapid searches and retrievals.
Other benefits of cloud archiving include centralised administration from a single location, the application of automated retention policies, security from data leaks, and mobile and web access to archived files.
An increase in the necessity for computing resources and the amelioration in networking technology have made several business organizations to outsource their computing and storage requirements. While all the above mentioned benefits make public cloud an attractive option to customers, it is also important to note that this type of cloud storage service paves the way for significant privacy and security risks.
All of the above mentioned concerns can be addressed by what is known as cryptographic cloud storage, which aims at providing the cost savings and functionality of a private cloud as well as the security of a public cloud. Regulatory compliance: The governments of most countries enforce laws and regulations that have to be followed by business organizations, for protecting their valuable data like financial records, medical records and PIIs. Security breaches: Even when a cloud storage provider implements the best possible security measures to protect the data stored in the cloud, there is always a chance of data breaches to take place. Data destruction and retention: In most circumstances, a customer would be responsible for the destruction and retention of data. Geographic restrictions: Data that are stored in certain countries would be subjected to legal regulations, even if the data collections were not performed there.
Integrity: Any type of unauthorized alteration of user data made by the cloud storage provider or any other third party must be detected by the user.
Confidentiality: The cloud storage provider must not know any details about the user’s data stored in the cloud.
Availability: Customer data must be easily available at all times, from anywhere and through any internet-connected device.
Data sharing: Customers must be able to share their data easily and effectively with people they trust. As the healthcare industry encounters several rapid changes pertinent to reduction in costs and enhancements in clinical outcomes, healthcare organizations, as a recent measure, are transforming to Electronic Health Records (EHRs). The main reason behind this discrepancy among American healthcare providers is the security, accessibility, and cost associated with EHR systems. As mentioned in an article on Wired, hackers or cybercriminals show particular interests on healthcare information or data, as its dollar value happens to be relatively substantial.
As the healthcare industry tends to adopt higher standards of medical images like 3D imaging, better image resolution, and video, there is a further increase in the amount of data that has to be processed and stored. The various advantages offered by cloud computing are apparent: enhanced agility, flexibility and efficiency, highly accessible resources, lower costs, and simplified management.
Howbeit, when it comes to moving to the cloud, the two major concerns to healthcare professionals are availability and security. With cloud based storage for medical or healthcare data, it has never been easier to protect all streamlined data and applications, in addition to protecting the same from intrusion and virus attacks. In addition to such concerns pertinent to the physical security of sensitive medical data, cloud solutions serving in the healthcare industry must also offer a strong physical infrastructure that contains several redundant layers for various aspects like connectivity, cooling, and power in order to ensure constant availability of the cloud. Traditionally storage solutions, as shown in Figure 1, use n-tiered architecture with SAN or NAS for storage, Relational Databases (RDBMS) for search and retrieval, and separate compute servers for processing. On-Demand Data Storage and Processing SolutionCloud computing offers the on-demand scalability of resources that can be leveraged for data storage to provide scalable storage. The proposed solution uses Hadoop, an open source storage solution, to provide replication, distributed file storage system and framework capabilities for running large data processing applications on clusters of commodity hardware. Next, the need to efficiently manage the large data, distributed on multiple machines across the cloud, poses a great challenge. Traditional vs Cloud Computing Based on On-Demand Storage SolutionsTable 1 provides a summary of the limitations of traditional solutions and how these new solutions address them. Architecture of Cloud Data Storage and Processing SolutionThe solution architecture for a cloud-based data processing and storage solution is shown in Figure 2. Specialized Cloud InfrastructureThe foundation layer of the solution consists of the cloud infrastructure to virtualize the underlying hardware and provide components on-demand. Distributed File SystemThe next layer in the solution is a distributed file system (DFS) that provides scalable and fault-tolerant file system to leverage the storage capacity that is available on multiple machines.
The on-demand solution bundles HDFS data nodes as Eucalyptus images and keeps the Hadoop name node on an isolated machine. Data Processing ModuleThe next component of the solution is a highly scalable data processing engine that is based on a parallel processing algorithm and is co-located with storage nodes.
In the proposed solution, Hadoop Job and Task tracker nodes are bundled as Eucalyptus images. Distributed Search EngineAnother important component of the solution is a distributed search engine that enables search operations on the data stored in a distributed file system.
With the Lucene implementation, MapReduce tasks are used to build the index files shards [10]. In case of Hive, the query engine is implemented using MapReduce tasks for distributed data processing. Monitor runtime usage of resource consumption and availability, thus enabling on-time warnings and accurate capacity management.
The web console interacts with a Hadoop monitoring component to retrieve the usage and availability information and display it graphically in a single monitoring console. Applicability of Cloud-Based On-Demand Storage SolutionThis solution architecture is efficient when processing and search is needed in addition to storage that is otherwise less efficient to implement using traditional approaches.
Related WorkCloud computing has quickly evolved and there's whole lot of commercial storage solutions available in the market. Zetta Enterprise Cloud Storage solutions support all unstructured data types and are backed by industry-leading data integrity and security. As customers traditionally store data in-house, they find it difficult to put their business at risk by moving their data out of their premises. SummaryTo handle the huge volume of data generated by applications in an organization, a scalable storage infrastructure is required.

The Internet of Things (IoT) is the most profound change in personal and enterprise IT since the creation of the Worldwide Web more than 20 years ago. In his session at Cloud Expo, Ed Featherston, a director and senior enterprise architect at Collaborative Consulting, will discuss the key considerations around quality, volume, timeliness, and pedigree that must be dealt with in order to properly fuel that engine.Aug. In his session at 18th Cloud Expo, Yu Hao, CEO and co-founder of SpeedyCloud, answered these questions and discussed the results of SpeedyCloud’s survey. For many that’s a good sign, as data has been proven to equal money – IF it’s ingested, integrated, and analyzed fast enough. Born out of proven success in agile development, cloud computing, and process automation, DevOps is a macro trend you cannot afford to miss.
It is not debatable whether cloud-based back-up systems are safe or not; the fact is that these systems are safe and reliable.
The traditional data storage and backup systems needed the purchase and installation of physical facilities which were expensive and vulnerable to vandalism and cyber threats.


Through secure networks characteristic of cloud computing, companies’ staff can share data and information even while located in remote places. Despite the advantages that cloud–based backup systems enjoy generally, there are a number of disadvantages that users have to contend with at least in the short term. In the event a business or person wants to terminate their cloud-based services, there are factors which, if not well considered, can be prohibitive and costly.
With all the pros and cons considered, however, cloud-based backup services still remain the most envied and technologically-aligned and thus the best. This can be catastrophic to business, and if the backup facilities are not quick and efficient enough, revenue may be lost.
Electronic documents enjoy the same status as formal printed documents and can represent legally binding contracts. It is essential that the stored information can be accessed rapidly both for the purposes of improved productivity and legal compliance. However, for most organisations and especially for those that either are unable to or do not wish to maintain an in-house archive a full could based archive is the optimal solution. The company provides a cloud-based service where customers are able to archive documents and files wherever they might be stored. This also provides the organisation with complete adherence to regulatory compliance, legal holds and eDiscovery. Tapscape is also a leading reviewer of the latest in apps for both iOS and Android devices, with over 2000 apps reviewed to date. When it comes to private cloud storage services, the infrastructure will be owned and managed directly by the customer and will be located on-premise, in the region of control of the customer.
By choosing to move their data to the cloud, customers will be able to prevent the costs associated with establishing and managing a private storage infrastructure, instead choosing to pay a cloud service provider for their storage needs. As a matter of fact, the risk factors pertinent to the integrity and confidentiality of user data happen to be one of the biggest hurdles when it comes to adopting to cloud storage services. The lack of proper security measures for protecting these records might put the organization into trouble and hence, storing such data on public cloud is not a viable option. However, if the customer stores the data on the cloud, it can be quite difficult for them to confirm the data’s integrity or to make sure that it was properly scrapped. This is because, once customers upload their data to the cloud, it would be difficult to know the exact location of the same, especially in the case of public clouds, which also cause increased legal exposures. This transformation is mainly to manage and systematize patient and all other medical data and records. In addition, there are two challenges that have to be addressed: one is the need to provide the necessary availability and performance for handling large sets of data, and the other is to protect sensitive healthcare information so that they meet certain industry regulations, like those dictated by the Health Insurance Portability and Accountability Act (HIPAA).
For instance, a person’s social security number would be worth just $1 while the same person’s medical identity would be worth $50, a significant increase in the value. In addition to the processing and storing of medical data, healthcare organizations must also take steps to protect those data. The cloud can be used by those top executives of healthcare organizations, who aim at augmenting patient care as well as generating revenue for the organization while reforming the meager resources of IT, to offer cost effective application support and capacity. This is because the IT administrators of healthcare organizations are required to protect the constant availability and security of medical data in order to meet the uncompromising standards.
However, there is still one visible feature of security that is often neglected, which is the data center’s physical security. Several applications have a large user base that produces a huge volume of data, for example, content in a community portal, emails in a web-based email system, and call log files generated at call centers. This solution architecture however requires expensive hardware and a long lead time to scale.
To efficiently and effectively manage the resources and data stored in the cloud, the cloud data storage and processing solution is presented here.
These layers provide a foundation for our solution to handle the QoS requirements of reliability and performance for huge volume and systems that are prone to breakdown.
Also it's necessary to know exactly when and how much capacity needs to be added or removed and then the complexity involved in provisioning new infrastructure.
The solution leverages Eucalyptus, an open source cloud computing framework to provide the base cloud infrastructure [7]. For this the solution uses the Apache Hadoop distributed file system as it provides reliable data storage through replication [8]. Whenever there is a storage requirement, data nodes are instantiated on new hardware using these images and are added to the cluster. To implement this, the Hadoop MapReduce solution [9] is leveraged as it helps partition the processing and executes them in parallel across several nodes, reducing the overall processing time. The index files shards are distributed across multiple Lucene search nodes to enable an efficient distributed search.
Hive offers a SQL-like interface and converts the search requests into MapReduce tasks that process the search operation in parallel to efficiently retrieve the results. The console will add new node instances and remove unused nodes running on the Eucalyptus to manage the storage capacity on-demand.
The management console would have a forecasting module to forecast the expected data volume.
Also they fear to risk of result of hardware failure or someone accidentally erasing or corrupting their high-value data outside their control.
This article described the architecture of cloud storage and a processing solution using the available open source options for a private cloud environment.

We will remove comments that include profanity, personal attacks, racial slurs, threats of violence, or other inappropriate material that violates our Terms and Conditions, and will block users who make repeated violations. These new classification techniques mean that traffic optimization, policy enforcement, and user experience are largely unaffected by encryption. From showcase success stories from early adopters and web-scale businesses, DevOps is expanding to organizations of all sizes, including the world's largest enterprises – and delivering real results. The technology embraced such as encryption, storage, server virtualization and data duplication are well structured to enhance security and efficiency in data management.
Businesses still using the old client-server models run the risk of exhausting of storage space. The encryption and safe transmission of data and information ensures no leakage during transmission, and this helps in maintaining the safety of companies’ vital data. The limits apply mostly to the data that is to be transferred on a day-to-day basis from the organization to the cloud-based servers’ systems.
Some providers may charge you early exit fees and termination charges which could be punitive to some extent. In cloud backup systems, the safety of data storage is such that files or whole folders can be retrieved and data restored in the event of system failures. It is essential that all appropriate files must be retained in a full, secure and accurate archive. By contrast, with cloud archiving there are many more degrees of freedom regarding where the archive is maintained and how data can be accessed.
For instance files can be archived from such resources as document libraries, network shares, SharePoint, home drives and Dropbox. Specifically, this means that access to the customer’s data will be completely under their control and will only be granted to trusted parties. For several customers, this technique offers numerous advantages, including reliability and availability at a comparatively reduced price. Maybe, in earlier years, customers did not have much concern over maintaining the privacy and security of their contents, which is now not the same with government organizations and enterprises. When the organization chooses cryptographic cloud storage, all their data will be encrypted by the data processor on-premise, which ensures data confidentiality to the customers. But, with cryptographic cloud storage, as the data will remain encrypted, data integrity is assured and can be verified at any point of time. All such concerns will be alleviated with the usage of a cryptographic cloud storage service, as the integrity of data can be easily verified and also the information required for data decryption will be available on-premise.
As the data will only be stored in encrypted forms in case of cryptographic cloud storage, all these laws and regulations will possess little or no impacts on the customer. With the conception of this new system and various other IT systems in the healthcare industry, health organizations must focus on digitizing and storing large amounts of sensitive medical data.
By possessing such medical information, criminals obtain the ability to carry out medical identity theft, which typically means receiving goods or services using the personal medical information of a different person, causing destruction in that individual’s records, making service providers liable and raising expenses for everyone involved.


As the amount of digitized medical data increases, so does the chances of being maliciously attacked. Storage on the cloud ensures organizations on pay-as-you-use services, reduced costs, and enhanced agility, enabling them to enjoy all possible external IT capabilities which they may not otherwise contain in-house.
The cloud storage system selected by the healthcare organization must implement onsite security systems, such as biometric scanners, armed security guards, and key cards, which will reduce the number of employees containing direct access to the stored sensitive data. Due to a large amount of data being added every minute and the need to keep historical data for various requirements such as legal, reference, data warehousing, and analytics, the systems' data size keeps growing exponentially. Our solution uses Eucalyptus, the open source cloud platform, to manage the underlying storage infrastructure. It will use the historical volume information and statistical forecasting models to project the storage requirement in the future. This solution is useful for applications where data is "Written once and read many times." This architecture may not be useful for scenarios that require frequent updates to the data. She has been working in the field of performance engineering and cloud computing for 6 years. We ask all readers to expect diversity of opinion and to treat one another with dignity and respect. Both can provide consistent measurement, visibility, and suggest performance improvements customized to help reach goals. Some businesses will capitalize on these promising new technologies and gain key insights that’ll help them gain competitive advantage. We build beautiful dashboards and even have fancy query languages to access and transform the data. Simply stated, communicate the most relevant offer to the right person and you will increase sales. The cutting edge technology employed by the cloud computing system has endeared it to many businesses and corporate establishments.
In addition to the technologies employed, there is a data surveillance system that operates around the clock to ensure that the data and the storage facilities are safe and sound. In cloud-based systems, all the major software and hardware systems are left to the service provider, allowing the businesses to concentrate on their core functions thereby boosting the bottom line.
This eliminates the need for physical means of moving information and works toward increasing productivity and revenue growth. These limitations have the potential of negatively affecting the company’s backup strategies. This process is called RaaS disaster recovery and is invaluable to getting a business back on track after an unforeseen disaster. She is a technology blogger and wants to express her gratitude to MyPCBackup review for their help. On the contrary, when it comes to a public cloud storage service, the infrastructure will be owned and managed by the cloud storage provider and will be located offsite or off-premise, in the region of control of the cloud storage provider. These organizations are now looking for best possible ways to protect all of their mission-crucial data and meet the regulatory obligations by preserving the integrity or confidentiality of data like financial and medical records, and personally identifiable information (PII).
However, despite the constant insistence of industry experts and government, the adoption of EHR still continues to lag behind among several healthcare providers of the US. In order to deal with the increasing frequency and cost of data breaches and also to comply with the different industry regulations, healthcare organizations and providers are found to be highly driven to take measures for protecting their sensitive medical information. When developed properly, cloud storage can also meet every other demand of the healthcare organization, including data security. This process will help in the reduction of internal data breaches by employees who are likely to be displeased. This requires a huge storage and processing infrastructure, incurring a high cost of procuring and maintaining it for companies.
There are some specialized open source cloud computing solutions such as Hadoop and Lucene that offer low-cost scalable alternatives for applications that need to process huge amounts of data. It provides on-demand scalability by enabling the addition, instantiation and management of the nodes in the cluster. Depending on the forecasted data, new data nodes can be added proactively before getting any capacity-full alerts from the monitoring system. Their standards-based integration APIs allow applications to quickly read and write to the cloud. Most of the existing solutions require the data to be moved out of the organization's premises.
A web-based console is proposed to proactively and quickly monitor and manage these systems.
Her research interests include adoption of cloud computing and cloud databases along with performance modeling. However, enterprises must overcome a number of critical challenges to bring these new solutions to market.
What do you do if you have to build a solution from the ground up that is expected to live in the field for at least 5-10 years? Despite having bottlenecks and their own share of problems, cloud-based backup services have helped most companies set their footsteps in the right technological direction. The burden of storage, the back-up infrastructure and all that it entails is left to the service provider. The cloud storage solutions are configured in such a way that they can accommodate your growing storage needs so that you will never get to a point where you will begin worrying whether all your folders and files can be accommodated. This is due to the fact that cloud backup services have more than one storage center where the data is kept under password protection. Therefore, potential customers will move their data to the cloud only if the cloud storage provider takes measures to address the issues discussed above. It has been found that, as of late 2012, only 69% physicians of the United States reported to have been using EHR systems for storing their data. Other typical challenges with such large data sets are how to store the data reliably and economically.
These nodes not only can contain a virtual machine with the operating system but they can also contain a complete software stack, thus enabling the creation of virtual appliances that can be instantiated and shut down on demand. It aggregates disk storage on multiple standard Linux servers to present one or more logical namespaces, and enables file access via standard file-access protocols (NFS, HTTP, WebDAV, and FTP). For having the on-demand scalable, distributed and fast-processing storage solution in the private cloud, very few options such as ParaScale Software are available. This on-demand storage system will provide IT administrators with the capability to rapidly bring up hundreds of servers, run parallel computations on them, and then shut down the instances as and when required, monitor and proactively manage their cloud environment, all with minimal effort and at a low cost. The more business becomes digital the more stakeholders are interested in this data including how it relates to business. In addition to optimizing their back-end AWS offerings, Amazon is laying the ground work to be a major force in IoT – especially in the connected home and office.
Consequently, digital marketers developed many ways to gather and leverage customer information to deliver targeted experiences. Contrasted with the traditional client-server models, cloud computing has advantages that outshine them. These centers are kept far away from each other, and this helps in the safe storage of data. While in other countries like the UK, Australia, New Zealand, Norway, and the Netherlands, there are way more than 95% of healthcare providers who have been found to use this system.
In addition, a cluster management module is included to automate and ease the management of these instances. However the open source-based solution proposed here provides a cost advantage over using commercial software. We're rapidly approaching a data production of 40 zettabytes a day – more than we can every physically store, and exabytes and yottabytes are just around the corner. Also the customization can be done, as per client-specific requirements, with minimal effort and cost.
