The NEW iPad Mini with a LARGER Display

A new note by Apple analyst Ming-Chi Kuo claims Apple is working on two new iPads: a 10.8-inch iPad and an 8.5 to 9-inch iPad mini. According to Kuo, these two devices will be similar to Apple’s recently launched iPhone SE, in the sense that they’ll have new, fast chips combined with an affordable price point.

There are no other specific details about the upcoming iPads, but the screen sizes are a pretty big deal, because the current low-cost iPad has a 10.2-inch display, while the iPad mini has (and has always had) a 7.9-inch display. This could mean that Apple will make the bezels around the screens smaller, perhaps as small as those on the iPad Pro.

If it turns out to be the case, that will be a big improvement for the iPad mini, whose form factor hasn’t really changed since the original one launched in 2012. I’ve written, at length, why I consider the iPad mini to be the best iPad, but here’s a summary: it’s practical, light, portable, it’s the perfect size for reading books and it’s fairly cheap. With a refreshed design and smaller bezels, it would be even better.

As for the 10.2-inch iPad, getting a bigger display wouldn’t hurt either, though I don’t think it would be as big of a deal as it is on the iPad mini.

There’s a couple of caveats here. First, just two months ago Kuo said that Apple is working on a new iPad mini, and he specifically said it would have a 7.9-inch display. Let’s hope he was talking about a different model, or was wrong.

There’s also the possibility that Apple goes the opposite way — instead of making the new iPads’ bezels smaller, it could make these devices slightly bigger to accommodate the larger displays. For the iPad, it wouldn’t matter much, but for the iPad mini it would be a disaster, because its portability and practicality is sort of its entire point.

iPhone SE (2020) – The BEST Budget iPhone

The original iPhone SE was Apple’s first budget phone. But that was four years ago. Until now, Apple had yet to release a newer model that was anywhere near as budget-friendly, easy to use, or small enough to comfortably hold one-handed.

At $399, the iPhone SE (2020) is finally here to give the company’s budget option a refresh. It also replaces the iPhone 8, which was the closest option to an updated SE that customers had since its launch in 2017. Although with a starting price of $699, the iPhone 8 wasn’t necessarily a true low-cost phone.

With a single rear camera, Touch ID, and a 4.7-inch display, the new SE packs almost all of the same features as the iPhone 8, allowing Apple to discontinue that model completely. Which, in a way, essentially makes the new iPhone SE the unofficial “iPhone 9.”

The new SE’s $399 price is just for the 64GB base model. If you’re looking for more storage, the 128GB version will cost you $449 while the 256GB configuration goes for $549.

But based solely on its specs, it’s clear this new iPhone SE isn’t for those who want the latest and greatest. It’s a great option for someone who is finally willing to let go of their dated flip phone, but  who also doesn’t want to pay a high cost or feel overwhelmed by confusing new features.

What’s more, the only available iPhone upgrade alternatives, which include the iPhone XS (the ‘X’ series being the first iPhones to ditch Touch ID completely) and up, require growing accustomed to Face ID, gesture navigation, and a much larger handset build. There’s also the fact that each of these phones comes with a relatively higher price tag.

The new iPhone SE, on the other hand, is the perfect choice for those who are content with the basic features of their current iPhones, but are desperately in need of an upgrade. Whether it’s because their phone is starting to slow down or they just want something a little more updated, the new iPhone SE is a solid replacement.

While the new iPhone SE is the smallest handset Apple currently offers, it’s not as small as its predecessor. In fact, it’s actually identical to the iPhone 8 in both size and design.

As far as dimensions go, the iPhone SE (2016) measured 4.87 inches long by 2.31 inches wide. Meanwhile, the second-generation version is slightly larger at 5.45 inches long by 2.65 inches wide. So, there’s quite a difference there.

Unlike the original iPhone SE which featured an aluminum body, the new model is made of glass on both the front and back. Only its sides are coated in aluminum. It does look and feel high-end for what’s considered a budget phone, though. My model came in the (Product) Red version, which I think adds to the sleek aesthetic, but it’s also available in black or white.

It’s also worth noting that, if you’re upgrading from the original iPhone SE, the 2020 version is a bit heavier. In comparison to the 2016 version which weighed in at 3.99 ounces, this model is 5.22 ounces. Having come from the iPhone 11 Pro (which weighs almost 6.63 ounces), the new SE felt super lightweight and small in my hands. But for those of you with the older models, it might feel like a bit of an adjustment at first.

I admit, it initially felt a little foreign to cradle the new SE in both my hands. My fingers were awkwardly crammed together as they rested on the back of the diminutively sized phone. Regardless, at 4.7-inches, it’s still the perfect size for someone with tiny hands like mine. It’s also ideal to use with one hand without feeling like you’re going to drop it.

WHAT IS CLOUD COMPUTING?

Cloud computing is the conveyance of various administrations through the Internet. These assets incorporate apparatuses and applications like information stockpiling, servers, databases, systems administration, and programming.

As opposed to keeping documents on a restrictive hard drive or neighborhood stockpiling gadget, cloud-based stockpiling makes it conceivable to spare them to a remote database. Up to an electronic gadget approaches the web, it approaches the information and the product projects to run it.

Cloud computing is a well-known alternative for individuals and organizations for various reasons including cost investment funds, expanded profitability, speed and proficiency, execution, and security.

Understanding Cloud Computing

Cloud computing is named thusly because the data being gotten to is found remotely in the cloud or a virtual space. Organizations that give cloud administrations empower clients to store documents and applications on remote servers and afterward get to every one of the information utilizing the Internet. This implies the client isn’t required to be in a particular spot to access it, enabling the client to work remotely.

Cloud computing takes all the truly difficult work engaged with crunching and handling information away from the gadget you bear or sit and work at. It additionally moves the majority of that work to immense PC bunches far away in the internet. The Internet turns into the cloud, and voilà—your information, work, and applications are accessible from any gadget with which you can associate with the Internet, anyplace on the planet.

Cloud computing can be both open and private. Open cloud administrations give their administrations over the Internet for a charge. Private cloud administrations, then again, just give administrations to a specific number of individuals. These administrations are an arrangement of systems that supply facilitated administrations. There is likewise a half and half choice, which consolidates components of both general society and private administrations.

KEY TAKEAWAYS :-

  • Cloud computing is the conveyance of various administrations through the Internet, including information stockpiling, servers, databases, systems administration, and programming.
  • Cloud-based stockpiling makes it conceivable to spare records to a remote database and recover them on request.
  • Administrations can be both open and private—open administrations are given online to an expense while private administrations are facilitated on a system to explicit customers.

Types of Cloud Services

Despite the sort of administration, distributed computing administrations furnish clients with a progression of capacities including:

  • Email
  • Capacity, reinforcement, and information recovery
  • Making and testing applications
  • Dissecting information
  • Sound and video spilling
  • Conveying programming on request

Distributed computing is as yet genuine new assistance, however, it is being utilized by various associations from huge companies to private ventures, charities to government organizations, and even individual customers.

Deployment Models

There are different kinds of Cloud, every one of which is not quite the same as the other. Open clouds give their administrations on servers and capacity on the Internet. These are worked by outsider organizations, who handle and control all the equipment, programming, and the general foundation. Customers access benefits through records that can be gotten to by pretty much anybody.

Private mists are held for explicit customers, typically one business or association. The association’s information administration focus may have a distributed computing administration. Numerous private distributed computing administrations are given on a private system.

Half and half mists are, as the name infers, a blend of both open and private administrations. This sort of model permits the client greater adaptability and advances the client’s foundation and security.

Types of Cloud Computing

Cloud computing is certifiably not a solitary bit of innovation like a microchip or a cellphone. Or maybe, it’s a framework principally contained three administrations: programming as-an administration (SaaS), foundation as-an administration (IaaS), and stage as-an administration (PaaS).

  • Software-as-a-service (SaaS)  includes the licensure of a product application to clients. Licenses are commonly given through a compensation as-you-go model or on-request. This sort of framework can be found in Microsoft Office’s 365.
  • Infrastructure-as-a-service (IaaS) includes a strategy for conveying everything from working frameworks to servers and capacity through IP-based availability as a component of an on-request administration. Customers can keep away from the need to buy programming or servers, and rather secure these assets in a redistributed, on-request administration. Famous instances of the IaaS framework incorporate IBM Cloud and Microsoft Azure.
  • Platform-as-a-service (PaaS) is viewed as the most mind-boggling of the three layers of cloud-based registering. PaaS shares a few similitudes with SaaS, the essential distinction being that as opposed to conveying programming on the web, it is really a stage for making programming that is conveyed through the Internet. This model incorporates stages like Force.com and Heroku.

Advantages of Cloud Computing

  • Cloud-based programming offers organizations from all segments various advantages, including the capacity to utilize programming from any gadget either through a local application or a program. Therefore, clients can convey their documents and settings over to different gadgets in a consistent way.
  • Cloud computing is something other than getting to records on numerous gadgets. On account of distributed computing administrations, clients can browse their email on any PC and even store records utilizing administrations, for example, Dropbox and Google Drive. Distributed computing administrations likewise make it workable for clients to back up their music, documents, and photographs, guaranteeing those records are quickly accessible in case of a hard drive crash.
  • It additionally offers enormous organizations tremendous cost-sparing potential. Before the cloud turned into a feasible other option, organizations were required to buy, develop, and keep up expensive data the executive’s innovation and foundation. Organizations can swap expensive server focuses and IT divisions for quick Internet associations, where workers communicate with the cloud online to finish their assignments.
  • The cloud structure enables people to spare extra room on their work areas or PCs. It likewise gives clients a chance to update programming all the more rapidly because product organizations can offer their items through the web as opposed to through increasingly customary, unmistakable techniques including circles or glimmer drives. For instance, Adobe clients can get to applications in its Creative Suite through an Internet-based membership. This enables clients to download new forms and fixes to their projects effectively.

Disadvantages of the Cloud

  • With the majority of the speed, efficiencies, and developments that accompany distributed computing, there are, normally, dangers.
  • Security has consistently been a major worry with the cloud particularly with regards to touchy restorative records and money related data.
  • Servers kept up by distributed computing organizations may succumb to cataclysmic events, inward bugs, and power blackouts, as well.
  • Likewise, with any innovation, there is an expectation to absorb information for the two representatives and chiefs.

WHAT IS CLOUD STORAGE?

Cloud storage is a route for organizations and customers to spare information safely on the web so it very well may be gotten to whenever from any area and effectively imparted to the individuals who are allowed consent. Distributed storage additionally offers an approach to back up information to encourage recuperation.

Cloud Storage Explained

Cloud storage offers a basic method to store or potentially move information in a protected and safe way. Consider purchasing another PC and requiring a quick and secure approach to exchange every one of your records.

Cloud storage can likewise be utilized to file information that requires long haul stockpiling yet shouldn’t be gotten to regularly, for example, certain money related records.

History of Cloud Storage

Cloud storage is accepted to have been designed by PC researcher Dr. Joseph Carl Robnett Licklider during the 1960s. Around two decades later, CompuServe started to offer its clients modest quantities of circle space so as to store a portion of their records. In the mid-1990s, AT&T propelled the main all online stockpiling administration for individual and business correspondence. From that point forward, various administrations have moved toward becoming picked up footing. Probably the most well known distributed storage suppliers are Apple (iCloud), (Amazon Web Services ), Dropbox, and Google.

How Cloud Storage Works

Cloud storage works by permitting a customer PC, tablet, or cell phone to send and recover documents online to and from a remote information server. Similar information is normally put away on beyond what one server with the goal that customers can generally get to their information regardless of whether one server is down or loses information. A distributed storage framework can work in putting away a specific kind of information, for example, computerized photographs, or can accommodate general stockpiling of numerous sorts of information, for example, photographs, sound records, content archives, and spreadsheets.

For instance, a workstation phone may store individual photographs both on her hard drive and in the cloud on the off chance that the PC is taken.

How Cloud Storage Helps

Cloud storage helps organizations with significant information stockpiling needs to spare a lot of room and cash by disposing of the requirement for a capacity framework on the business premises. The distributed storage supplier possesses and keeps up all the essential equipment and programming so the cloud clients don’t need to. Obtaining continuously distributed storage may cost more over the long haul, yet it very well may be fundamentally more affordable forthright. Further, organizations can immediately scale up or down how much distributed storage they approach as their stockpiling needs change. The cloud additionally empowers representatives to work remotely and outside of customary business hours while encouraging smooth archive joint effort by permitting approved representatives simple access to the most refreshed rendition of a document. Utilizing the cloud to store documents can likewise positively affect the earth since it chops down vitality utilization.

Cloud Storage Security

There is such a great amount of consideration on distributed storage today in the advanced period because such an extensive amount our delicate individual information is put away in the cloud whether we deliberately store it there or whether an organization we work with chooses to store it there. Subsequently, cloud security is a significant concern. Clients wonder whether their data is protected, and expanding information ruptures have shown that occasionally it isn’t. Clients are likewise worried about whether the information they have put away on the cloud will be available when they need it.

While distributed storage may appear to be powerless because of the predominance of hacking, the other options, for example, on location stockpiling, have security vulnerabilities, as well. The organization gave distributed storage can improve security by giving representatives an option in contrast to utilizing their records to back up and move documents that they have to access outside the workplace.

A decent distributed storage supplier will spare information in numerous spots with the goal that it endures any human mistakes, hardware disappointments, or cataclysmic events. A legitimate supplier will likewise store and transmit information safely so nobody can get to it without authorization. A few clients may likewise necessitate that information be put away so that it must be perused yet not changed; this component, as well, is accessible through distributed storage.

Cloud Storage Technology and Its Applications

WITH THE RISE OF CLOUD COMPUTING[1-2] AND SOFTWARE AS A SERVICE (SAAS)[3-5], CLOUD STORAGE HAS BECOME THE FOCUS OF ATTENTION IN INFORMATION STORAGE. IT, UNLIKE TRADITIONAL STORAGE, COMPRISES NOT ONLY HARDWARE DEVICES, BUT IS A SYSTEM OF NETWORK AND STORAGE EQUIPMENT, SERVER, APPLICATION SOFTWARE, PUBLIC ACCESS INTERFACE, ACCESS NETWORK, AND CLIENT PROGRAMS[6]. SINCE ITS INTRODUCTION, CLOUD STORAGE HAS ATTRACTED GREAT INTEREST FROM SERVICE PROVIDERS.

A user’s local data can be stored in online spaces provided by a Storage Service Provider (SSP). A user need not build their own data centers but can apply for services from the SSP. In this way, repeated construction of storage platforms can be avoided and expensive investments in hardware and software infrastructure be saved.

1 Cloud Storage
    Cloud storage differs from traditional storage in many aspects. In terms of functionality, it is designed to deliver many online storage services, whereas traditional storage systems are primarily designed for high performance computing and transaction processing. In terms of performance, cloud storage places great importance on data security, reliability, and efficiency. With a larger number of users, a wider service range, and a complex and ever-changing network environment, cloud storage systems face greater technical challenges than traditional systems when delivering high-quality services. In terms of data management, cloud storage systems not only offer access to traditional files such as Portable Operating System Interface for Unix (POSIX), but also support mass data management for providing public service support functions, and maintaining data in the background.

A cloud storage platform can be classified into four layers: data storage layer, data management layer, data service layer, and user access layer. Figure 1 shows the architecture of a cloud storage platform.

(1) DATA STORAGE LAYER
A CLOUD STORAGE SYSTEM OFFERS DIVERSE STORAGE SERVICES, AND ALL DATA STORED IN THE SYSTEM FORMS A MASSIVE POOL. FOR EFFICIENT STORAGE, THIS DATA SHOULD BE PROPERLY ORGANIZED. TRADITIONAL DATA ORGANIZATION USES A SINGLE SERVER AND CANNOT MEET THROUGHPUT AND STORAGE CAPACITY REQUIREMENTS OF MULTIPLE USERS IN A WIDE AREA NETWORK (WAN)[7]. A PEER-TO-PEER (P2P) ARCHITECTURE BASED ORGANIZATION METHOD REQUIRES A LARGE NUMBER OF NODES AND COMPLICATED CODING ALGORITHM TO ENSURE DATA RELIABILITY[8]. IN CONTRAST, USING MULTIPLE STORAGE SERVERS TO ORGANIZE DATA BETTER SATISFIES THE REQUIREMENTS OF ONLINE STORAGE SERVICES[9]. DISTRIBUTED DATA CENTERS CAN PROVIDE GOOD QUALITY OF SERVICE (QOS) FOR A LARGE NUMBER OF USERS IN DIFFERENT GEOGRAPHICAL REGIONS[10].

By interconnecting different types of storage devices, the data storage layer can manage massive amounts of data in a unified way, and can employ centralized management, status monitoring, and dynamic capacity expansion of storage devices. A cloud storage system is essentially a service-oriented distributed storage system.

(2) Data Management Layer
The data management layer provides the upper layer with a unified public management interface for different services. With functions such as user management, security management, replica management, and strategy management, this layer seamlessly associates upper-layer applications with lower-layer storage services. It also promotes cooperation between storage devices, enabling them to offer diverse and optimized services.

(3) Data Service Layer
The Data Service Layer Deals Directly With Users And Can Be Flexibly Expanded. Depending On User Demands, Different Application Interfaces Can Be Developed To Provide Services Such As Data Storage, Space Leasing, Public Resource, Multi-User Data Sharing, Or Data Backup.

(4) User Access Layer
In the user access layer, an authorized user can log into the cloud storage platform from any location via a standard public application interface and access cloud storage.

As an alternative to purchasing storage devices and deploying storage software, cloud storage has the following advantages:

(1) LOW COST AND QUICK RETURN
IN BUILDING A STORAGE PLATFORM THAT MEETS INFORMATION MANAGEMENT DEMANDS, PURCHASING STORAGE DEVICES AND DEPLOYING SOFTWARE REQUIRES HEAVY INITIAL INVESTMENT. SOFTWARE DEVELOPMENT OFTEN INVOLVES A LONG PROCESS OF FEASIBILITY ANALYSIS, REQUIREMENT ANALYSIS, SOFTWARE DESIGN, CODING, AND TESTING.  BY THE TIME THE SOFTWARE IS DEVELOPED, THE DEMANDS MIGHT HAVE BEEN CHANGED SO THAT THE SOFTWARE HAS TO BE REDEVELOPED. THIS REDUCES THE QUALITY OF SERVICE (QOS), INCREASES COST, AND DELAYS THE PROGRESS OF INFORMATION MANAGEMENT. ENTERPRISES REPEATEDLY INVEST IN TRADITIONAL LOW-TECH STORAGE APPROACHES; AND FOR AN INDIVIDUAL ENTERPRISE, THIS MEANS CYCLIC, HIGH-COST TECHNICAL UPGRADES.

Taking The Cloud Storage Approach, Terminal Devices Need Only Be Configured To Receive Storage Services So That Heavy Investment In Platform Building Is Not Necessary. Storage Services Can Be Purchased According To The Number Of Users And The Usage Time Span, Thereby Avoiding The Risk Of Heavy Initial Investment And Reducing Usage Cost. Services Can Be Used Immediately And Conveniently.

(2) Ease of Management
Traditional storage systems require maintenance to be performed by dedicated IT staff, and this incurs additional cost. Maintenance and upgrade of a cloud storage system, however, is performed by the service provider, so that professional services are provided at the lowest cost.

(3) Flexibility
Traditionally, once an investment has been made into purchasing devices or deploying software, the storage system cannot be dynamically adjusted during its lifetime. As devices are renewed, disposal of the existing outdated hardware platform becomes difficult. Ever-changing business needs may require the software to be constantly updated, upgraded, or even redeveloped. So high maintenance costs are incurred as a necessity and are to some extent beyond control. Cloud storage services are generally charged according to the number of users, usage time, and service items. On-demand services released by an enterprise can be changed anytime according to business needs, personnel changes, or financial status.

2 Application Of Cloud Backup
    Cloud Storage Has A Variety Of Applications, Including Data Backup, Data Sharing, And Resource Service. It Can Also Provide Standardized Interfaces For Other Network Services. The Following Self-Developed B-Cloud System Is An Example Of Cloud Storage Technologies And Applications.

The deployment structure of B-Cloud is illustrated in Figure 2. It consists of three cloud levels.

The top level is called wide area (public) cloud. It covers all areas that backup clients can access via the WAN. Wide area cloud servers include wide area manager and wide area cloud storage nodes.

The middle level is called regional cloud and usually divided by geographic region (province or prefecture). Similar to wide area cloud, it has service nodes such as regional cloud manager and regional cloud storage servers.

The lowest level is called local (private) cloud. This is divided either by small geographical region or by an entity such as enterprise, institute, or campus. Local cloud can run on a WAN or Local Area Network (LAN), and its users are only those within the cloud. It has service nodes such as local manager and private cloud storage servers.

Like wide area cloud, regional and private clouds have multiple local storage nodes that serve multiple backup clients.

The topology of the B-Cloud system looks like a tree; the wide area cloud acts as the root node, and regional and local clouds act as branch nodes. Each node has its own manager and storage nodes that perform backup task scheduling and backup data access. All nodes—including wide area cloud, regional clouds, and local clouds—are physically connected. Nodes at any two adjacent levels have a parent-child relationship in which the child node can be viewed as a special user of the parent node. The topological structure is very scalable. Even though only three levels are currently defined in the system, any node can be split into more levels when the number of users grows or the service area expands.

When a new user (or backup client) registers in the system, it first visits the super director server of the system—which is responsible for global user management. The server then assigns the user a backup cloud node according to predefined assignment strategies and user information (such as the segment or region of the user’s IP address, organization of the user’s email address, or the user’s geographic location). User information is maintained by the system’s super director server. After registration, the backup client can log onto the system and communicate with the backup manager and storage nodes of the specific cloud to receive a service.

The principle of proximity access dictates that the nearer the client, the higher the data transmission efficiency and the lower the cost. An hierarchical topological structure creates an orderly relationship between multiple scheduling servers and multiple storage servers of the backup system, enabling the system to better serve backup clients in different regions.
The characteristics of cloud backup determine application requirements, which in turn drive the development of three key backup technologies: parallel task scheduling, data organization and compression, and backup security. These technologies are research subjects of the B-Cloud system, and involve several aspects of cloud backup service architecture. The relationship among them is illustrated in Figure 3.

Cloud backup differs from traditional backup software in the following ways:

(1) Number of Users
Backup software is traditionally used in a LAN or WAN by specific user groups. Because the number of users is small, only a small number of storage servers are usually configured—for ease of deployment, ease of maintenance, and to reduce cost. User access paths to the servers are fixed, and dynamic assignment or adjustment is not required to meet different scenarios.
In contrast, cloud backup is designed for a large number of users in the WAN. As this number grows, the system has to be configured with multiple storage servers to meet scalability requirements. The system should also be capable of processing concurrent access requests from a large number of users, and assigning proper target storage servers to these users by means of efficient parallel scheduling policy. Load balance and high storage utilization can thus be achieved among all storage servers. The process is completely transparent to users.

(2) Amount of Data
The difference in user numbers between cloud backup and traditional backup software represents a great difference in the amount of data to be processed. Backup data generated by large-scale users in the WAN may easily reach one TB or even one PB. Thus, proper data organization methods and compression algorithms are of great importance to improve the transmission and storage efficiency of massive amounts of data. The ultimate objective of these methods and algorithms is to improve system performance, reduce hardware costs and save energy.

(3) Service Security
Cloud backup must be compatible with heterogeneous data platforms of different backup clients; must ensure data integrity at the block, file and application levels; must adapt to a complex and changing WAN environment; and must guarantee data security.

Cloud backup systems have higher requirements on reliability than common backup software. However, people unconsciously feel it safer to backup critical data on visible devices. Doubts may arise about the security of backing up private data in faraway data centers.
On the one hand, cloud backup is prone to various abnormalities; on the other, users subjectively impose higher security requirements on cloud backup than on backup software. Security is therefore a pressing area of study for cloud backup.

According to the characteristics of cloud backup, the study of cloud backup focuses on:

(1) Command Flow
The B-Cloud system consists of backup clients, manager, and storage servers. The manager is the administrative center of the entire system, responsible for task scheduling, operation management, and status monitoring in the service process.

After receiving a service request from a backup client, the three parts of the system implement bidirectional security certification; and importantly, the manager completes job scheduling to establish a connection between the backup client and the storage server. At this point, the system begins to deliver the backup or recovery service.

(2) Data Flow
The backup or recovery data flow is transmitted between the backup client and the storage server without passing the manager. This method, whereby data goes directly from the source to the destination and does not pass any intermediate node, improves efficiency and also balances the overall load of the system. For data transmission and storage, backup data organization and compression are key.

(3) Service Security
Security of cloud backup involves the security within service platform, modules, and coordination and communication between modules. This issue requires in-depth discussion which is not intended here.

3 Conclusion
    This paper introduces cloud storage technology and takes cloud backup as an example to discuss issues to be addressed in cloud storage application.

A trend of technology development is to satisfy requirements with services. Cloud storage conforms to this trend. However, in-depth study is needed into the implementation of cloud storage and its widespread applications.
