Understanding Technical Aspects of Cloud Computing with different Computing Models and its Benefits

Understanding Technical Aspects of Cloud Computing with different Computing Models and its Benefits

Cloud computing is the development of parallel computing, distributed computing, grid computing and virtualization technologies which defines the shape of a new era. Cloud computing is an emerging model of business computing. It means storing and accessing data over the internet instead of your computer’s hard drive. That means all the data what you are going to access is on air i.e., on internet. In this paper we have enlighten different computing models from which we have finally concluded that Cloud Computing is one of its types which is a combination of cluster and grid computing models. Many people have different opinion about the term Cloud Computing, many even says that it is a new technology and new establishment on internet, but Cloud Computing is available on internet since the day the Internet was evolved. In this paper we have focused on technical aspects of cloud computing and have explained it via different computing models. This paper provides a better understanding of the cloud computing and also explains the evolution of it by understanding the emergence of internet with benefits.

Review on Benefits and Security Challenges of          Cloud Computing

Review on Benefits and Security Challenges of Cloud Computing

There are many benefits as mentioned above, even though cloud computing has many challenges. While moving from owning site to cloud space, companies must aware about the benefits and challenges of cloud computing. While analysing these challenges, security of data is the most tedious work in cloud computing. According to a survey carried out by Gartner [7], more than 70% of Chief Technical Officers believed that the primary reason for not using cloud computing services is that of the data security and privacy concerns. Convincing the organizations especially small ones about security concern is a tedious work; they are not ready to throw away their infrastructure and immediate move to cloud. Most of the organizations are closely watching this issue and not ready to shift to cloud space, this is main reason in the lack of maturity

technology enables a vendor’s cloud software to automatically move data from a piece of hardware that goes bad or is pulled offline to a section of the system or hardware that is functioning or operational. Therefore, the client gets seam- less access to the data. Separate backup systems, with cloud disaster recov- ery strategies, provide another layer of dependability and reliability. Finally, cloud computing also promotes a green alternative to paper-intensive office functions. It is because it needs less computing hardware on premise, and all computing-related tasks take place remotely with minimal computing hard- ware requirement with the help of technological innovations such as virtual- ization and multitenancy. Another viewpoint on the green aspect is that cloud computing can reduce the environmental impact of building, shipping, hous- ing, and ultimately destroying (or recycling) computer equipment as no one is going to own many such systems in their premises and managing the offices with fewer computers that consume less energy comparatively. A consolidated set of points briefing the benefits of cloud computing can be as follows: 1. Achieve economies of scale: We can increase the volume output or pro-

customers while maintaining the same level of quality and services [10, 11]. Both features intend to improve the agility, collaboration, rapid adaptation to the demand triggered fluctuations utilization of resources and availability of services without spatio-temporal restrictions in the cost-effective manner [12]. Due to ability of the cloud computing systems to provide with wide range of services ranging from computationally intensive services to the light-weight applications, they have assumed tremendous attraction for the different levels of business operations depending on IT resources [4, 12]. The adoption of cloud computing enables the organizations to reduce the upfront IT investment for purchasing IT infrastructures, software development and licensing various applications. Besides, governments showed an expression of interest in adopting the cloud computing applications in order for reducing the operational costs of the public projects, and enhancing the reachability, availability, and capabilities of their services delivered to the public domain [13, 14]. Although there is the plethora of benefits of the services and applications delivered to the customers through the cloud computing model, but there are significant issues and challenges in the way of successful adoption; and the most important one is the security issue which is reported to hamper the adoption of cloud computing in different organizations [5, 14]. As the cloud computing model is still in its infancy, due to which it involves uncertainty at different levels such as applications, data storage, data access points, network, hosting. The Service level agreements (SLA) does not include specific guarantees about the security and privacy of the customer’s data hosted on the servers of the cloud providers [15, 16]. The data from the multiple tenants exist on the same server without solid security controls over the data from each individual user. In addition, the instance of hosting valuable data from the customers on the publicly accessible servers enhances the probabilities of attack from malicious agents [17].

Revocable Storage Identity Based Encryption and Sharing Information in Cloud

Revocable Storage Identity Based Encryption and Sharing Information in Cloud

Abstract- Cloud computing offers a flexible and convenient way to share data, which provides diverse benefits to society and people. But there is a natural resistance for users to directly outsource shared data to the cloud server because the data often contains valuable information. Therefore, it is necessary to place a cryptographically improved access control in the shared data. Identity-based encryption is a promising cryptographic primitive for building a convenient data exchange system. However, access control is not static. That is, when the authorization of certain users has expired, there must be a mechanism that can eliminate it from the system.

Desktops are another computing resource that can be virtualized. Desktop virtualization is enabled by several architectures that allow remote desktop use, including the X Window System and Microsoft Remote Desktop Services. The X Window System, also known as X Windows, X, and X11, is an architecture commonly used on Linux, UNIX, and Mac OS X that abstracts graph- ical devices to allow device independence and remote use of a graphical user interface, including display, keyboard, and mouse. X does not include a windowing system—that is delegated to a window manager, such as KDE or Gnome. X is based on an MIT project and is now managed by the X.Org Foundation. It is available as open source software based on the MIT license. X client applications exist on Linux, UNIX, Mac OS X, and Windows. The X server is a native part of most Linux and UNIX systems and Mac OS X and can be added to Windows with the Cygwin platform. The X system was designed to separate server and client using the X protocol and lends itself well to cloud computing. X Windows is complex and can involve some troubleshooting, but because it supports many varied scenarios for its use, it has enjoyed a long life since it was first developed in 1984.

However, sometimes it can be hard to classify the characteristics in one of the two categories, since even for some quantitative attributes it makes sense that the users express their preferences in a qualitative manner. There are a number of metrics that can be seen as qualitative but at the same time with some reasonable assumptions they can be precisely quantified (e.g. Interoperability, Usability etc. ) or that they can be resolved in a number of lower level metrics, involving both quantitative and qualita- tive attributes (e.g. Serviceability etc.) or including both precise and imprecise values. For instance, usability metric has been defined as a quantifiable attribute [1] in the sense of average time experienced by users of the cloud service to install, learn, un- derstand and operate it. But, often this average time is not enough to define how usa- ble a cloud service is, since this information is often vague and imprecise. It might be the case that the average installation or learn time for a cloud customer about a specif- ic service is relative short because of the customer’s huge experience in the specific domain and not because the service is really usable for an average user. It would be an oversight to ignore the degree of difficultness that previous users experienced based on their degree of expertise, when they tried to install, learn, understand and operate the specific cloud service. This value is highly subjective, uncertain and often is available through linguistic terms when previous users are expressing their opinions.

There’s growing sentiment among many cloud experts that ultimately hybrid adoption will be most ad- vantageous for many organizations. Warrilow says “for some time Gartner has advised that hybrid is the most likely scenario for most organiza- tions.” Staten agrees with the notion for two reasons. First, “some appli- cations and data sets simply aren’t a good fit with the cloud,” he says. This might be due to application architec- ture, degree of business risk (real or perceived), and cost, he says. Second, rather than making a cloud-or-no- cloud decision, “it’s more practical and effective to leverage the cloud for what makes the most sense and other deployment options where they make the most sense,” he says. In terms of strategy, Staten recommends regularly analyzing deployment decisions. “As cloud services mature, their applica- bility increases,” he says.

Hadoop MapReduce and the LexisNexis HPCC platform are both scalable archi- tectures directed towards data-intensive computing solutions. Each of these system platforms has strengths and weaknesses and their overall effectiveness for any appli- cation problem or domain is subjective in nature and can only be determined through careful evaluation of application requirements versus the capabilities of the solution. Hadoop is an open source platform which increases its flexibility and adaptability to many problem domains since new capabilities can be readily added by users adopt- ing this technology. However, as with other open source platforms, reliability and support can become issues when many different users are contributing new code and changes to the system. Hadoop has found favor with many large Web-oriented companies including Yahoo!, Facebook, and others where data-intensive computing capabilities are critical to the success of their business. Amazon has implemented new cloud computing services using Hadoop as part of its EC2 called Amazon Elastic MapReduce. A company called Cloudera was recently formed to provide training, support and consulting services to the Hadoop user community and to pro- vide packaged and tested releases which can be used in the Amazon environment. Although many different application tools have been built on top of the Hadoop platform like Pig, HBase, Hive, etc., these tools tend not to be well-integrated offer- ing different command shells, languages, and operating characteristics that make it more difficult to combine capabilities in an effective manner.

The Heartbeat Service periodically collects the dynamic performance information about the node and publishes this information to the membership service in the Aneka Cloud. These data are collected by the index node of the Cloud, which makes them available for services such as reserva- tions and scheduling in order to optimize the use of a heterogeneous infrastructure. As already dis- cussed, basic information about memory, disk space, CPU, and operating system is collected. Moreover, additional data are pulled into the “alive” message, such as information about the installed software in the system and any other useful information. More precisely, the infrastructure has been designed to carry over any type of data that can be expressed by means of text-valued properties. As previously noted, the information published by the Heartbeat Service is mostly con- cerned with the properties of the node. A specific component, called Node Resolver, is in charge of collecting these data and making them available to the Heartbeat Service. Aneka provides different implementations for such component in order to cover a wide variety of hosting environments. A variety of operating systems are supported with different implementations of the PAL, and differ- ent node resolvers allow Aneka to capture other types of data that do not strictly depend on the hosting operating system. For example, the retrieval of the public IP of the node is different in the case of physical machines or virtual instances hosted in the infrastructure of an IaaS provider such as EC2 or GoGrid. In virtual deployment, a different node resolver is used so that all other compo- nents of the system can work transparently.

SDN has two main advantages over traditional networks in regards to detection and response to attacks: (1) the (logically) centralized management model of SDN allows administrators to quickly isolate or block attack traffic patterns without the need to access and reconfigure several heterogeneous hardware (switches, routers, firewalls, and intrusion detection systems); (2) detection of attacks can be made a distributed task among switches (SDN controllers can define rules on switches to generate events when flows considered malicious are detected), rather than depending on expensive intrusion detection systems. SDN can also be used to control how traffic is directed to network monitoring devices (e.g., intrusion detection systems) as proposed in [31]. Quick response is particularly important in highly dynamic cloud environments. Traditional intrusion detection systems (IDS) mainly focus on detecting suspicious activities and are limited to simple actions such as disabling a switch port or notifying (sending email) to a system administrator. SDN opens the possibility of taking complex actions such as changing the path of suspicious activities in order to isolate them from known trusted communication. Research will focus on how to recast existing IDS mechanisms and algorithms in SDN contexts, and development of new algorithms to take full advantage of multiple points of action. For example, as each switch can be used to detect and act on attacks, [16] has shown the improvement of different traffic anomaly detection algorithms (Threshold Random Walk with Credit Based rate limiting, Maximum Entropy, network traffic anomaly detection based on packet bytes, and rate limiting) using Openflow and NOX by placing detectors closer to the edge of the network (home or small business networks instead of the ISP) while maintaining the line rate performance.
