Introduction WHAT IS CLOUD COMPUTING? It is a computing paradigm, wherein a huge cluster of systems are interconnected in a public or private network to provide highly resilient infrastructure for housing business critical applications and confidential files in a secured environment. It delivers computing services over the web and allows individuals as well as businesses to use hardware components and software applications managed by the third party service providers at remote locations. The cloud computing facilitates easy access to resources and information from anywhere over a network with the internet connectivity. By embracing this technology, users can experience significant cost benefits as it transforms the capital-intensive data center set-up to a variable priced environment. The technology is based on the fundamental principal of reusability of the IT capabilities. The most popular examples of cloud services are online file storage, webmail, online business applications, and social networking sites.

KEY CHARACTERISTICS OF CLOUD COMPUTING Cloud technology is enticing various sectors across the globe owing to the following characteristics it offers to the businesses:

On-Demand Capabilities: This feature enables users to access cloud services via an online control panel. It allows both individuals and businesses to scale-up or down infrastructure as per their requirement, without disrupting the service provider. It is also related to the utility model, pay-as-you-grow subscription method, where the user only pays for the resources used during the subscription period. Elasticity: The technology can be rapidly and easily provisioned to match companyâ&#x20AC;&#x2122;s changing business requirements. It facilitates clients to quickly remove or add resources at any time. Wide Network Access: Another important feature of cloud computing is that users can access important files and documents from their office workstation, laptops, or while on move through smart phones, and tablets. The information can be read or retrieved from anywhere with a simple online access. Resource Pooling: A cloud service model pools together computing resources of the service provider to serve various users by using the multi-tenacity model, with different virtual and physical resources dynamically assigned/reassigned in line with the clientâ&#x20AC;&#x2122;s demand. According to Gartner, resource pooling leads to economies of scale.

Multi Tenancy: This characteristic was suggested by the Cloud Security Alliance. It refers to the requirement of policy driven enforcement, governance, service level agreements, segmentation, and billing/chargeback models for different businesses. The idea of many tenants sharing infrastructure or resources enables users to leverage the highly secured and scalable cloud infrastructure with other business units.

Why should you move your business from in-house hosting to cloud? Cloud computing is the latest buzz in the IT industry. With the surging growth of social, mobile, and cloud-based applications, the technology is having a significant impact on the users to leverage its benefits for accessing mission critical applications and files from any platform. It has enabled companies of all sizes to minimize infrastructure costs while expanding computational capabilities.

LETâ&#x20AC;&#x2122;S TAKE A QUICK GLANCE AT THE MAJOR REASONS THAT HAVE COMPELLED BUSINESSES TO MIGRATE THEIR IN-HOUSE INFRASTRUCTURE TO CLOUD Simplicity: The cloud arrangements are simpler as compared to the complicated traditional inhouse infrastructure, which requires outlay for system installation, price negotiations, approvals from the area managers, and stretched order delivery period. Cloud Hosting only requires a service request to the vendor to install the platform. Improved Compatibility and Integration: Another important reason for migrating to cloud is the ease with which the platform can configure multiple applications to share critical business data or information. Moreover, the technology makes interoperability central to the cloud hosting service by using industry standards, such as Apache, MySQL, and PHP. This eradicates the compatibility issues that an organization may face while running its own server. Reliability: Cloud computing is highly reliable as the model takes care of various issues, such as network failure, timeouts etc., that may slow down your productivity. Even if a business needs complete control over dedicated hosting services, infrastructure outsourcing to a cloud vendor guarantees hardware. Economies of Scale: With the continuous flow of Big Data, workloads are substantially growing at an incredibly faster rate. Cloud Infrastructure as a Service (IaaS) has enabled enterprises to overcome this issue by shifting the ownership as well as management of its physical server to managed services. This enables enterprises to trim down their system implementation costs, upgradation, and reduce human interventions, which further saves time and money while improving business efficiency.

Availability

Data stored in the cloud is duplicated across various physical machines to ensure security of your critical business information against any cyber threat, catastrophe, natural calamity, etc. Moreover, service providers perform due-diligence to ascertain the highest level of security. Network Uptime: The cloud technology is based on the efficient allocation of resources in a virtualized environment to provide uninterrupted services to the users. This means, even if one of the servers within the network fails, the other connected servers continue to provide service. Cost Savings: This is another significant reason that compels users to migrate their data & applications from on-premise hosting to cloud computing solution. The technology facilitates clients to reduce their capital expenditure on infrastructure. Moreover, cloud services allow businesses to focus their valuable time on formulating strategies to improve their products and services. Both private and public cloud hosting tenders the ability to instantly deploy as well as scale VMs in line with the business requirements.

What is ‘as a service’? As a service refers to three service models of cloud computing that can be described as Software as a Service, Infrastructure as a Service and Platform as a Service. These service models reduce IT support costs, improve the security of mission-critical applications, allow users to take control over software deployment and configuration settings, and above all house, run and maintain storage, hardware servers and networking components. The purpose is to streamline the functionalities of IT infrastructure without making compromises on the storage, accessibility and running of critical business applications.

Cloud Platforms

The prolific cloud computing has four service models, namely:    

Infrastructure-as-a-Service (IaaS) Platform-as-a-Service (PaaS) Software-as-a-Service (SaaS) Now everything will be available as AaaS

Let’s start our discussion with the foremost service delivery model:

1. Infrastructure-as-a-Service (IaaS): Accelerates growth and deliver new revenue streams Infrastructure-as-a-Service is a standardized and highly automated cloud computing layer, where an enterprise uses a pay-as-you-go infrastructure from a service provider. This model help businesses to slash down cost on hardware procurement, reduces ROI risk, and simplifies and automate scaling. It provides swift provisioning of storage capacity, virtual-machine disk

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

image library, processing, networks, and other fundamental computing resources over a network. IaaS clouds often delivers additional resources like firewalls, IP addresses, load balancers, software bundles, and virtual local area networks (VLANs).

How Businesses Can Benefit from IaaS? There is a fine difference in the perceived benefits of IaaS cloud by the SMB and enterprise sectors. SMBs consider IaaS for real cloud advantages like: higher uptime, usage-based payments and low capital investments. On the other hand, large enterprises observe benefits on the operational side like: reduced risk of technology obsolescence, and capability to focus on core business initiatives. Lower TCO: IaaS enables IT services to be delivered as a subscription service, eradicating up-front investments and trimming down operational costs. This enables businesses to move from a CAPEX to OPEX-based business model. High Scalability: IaaS allow businesses to easily scale up/down to respond to changing market demands. Businesses subscribing IaaSsolution need not to invest in IT software, hardware, and personnel every time their business has to change scale. The resources can be accessed from anywhere, provided you have internet connectivity. Boosts Focused Approach: IaaS solutions can be provisioned in minutes over the network, providing substantial amount of control to businesses over required specifications to meet changing demands. On demand provisioning of IaaS services, help businesses to shift their focus

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

from IT infrastructure to core competencies and business success. Metered Services: Infrastructure-as-a-Service model eliminates the need of investing intoassets and services by allowing businesses to pay for the services holistically tailored to meet their business needs. Each infrastructure component is provided as a service, such as server-as-aservice, hardware-as-a-service, etc. which adds flexibility to those who are looking for specific services.

Why Businesses are Moving to IaaS?

The below graph explicitly describes the major reasons for businesses moving to IaaS.

2. Platform-as-a-Service (PaaS): Helping Organizations to Achieve the Fastest Time to Market Platform-as-a-Service is a standardized, shared and highly scalable application development and deployment platform that is delivered as a service. This cloud service delivery model includes computing platform (hardware architecture, runtime libraries, and operating systems), and a solution stack (middleware, database, and applications) as well as development, security, integration, and management capabilities, all delivered as a service. It enables businesses to merge existing applications on the same integrated platform, and help building new apps with the minimum cost of management and ownership.

How Businesses Can Benefit from PaaS? PaaS solutions include tools, APIs, and templates that make it easier and convenient for application developers to build, run, test and manage their software. PaaS services are available on demand, with the provider responsible for managing and maintaining hardware and software that supports PaaS functionality. Lower TCO: Companies using PaaS have reported operational savings of up to 50% when compared to having individual project teams managing their own technology stacks. When businesses opt for PaaS services they donâ&#x20AC;&#x2122;t have to invest on expensive setups, software licensing, maintenance, training and support, which apparently reduces total cost of ownership. On demand service: Users can use platform according to their business requirement on a subscription basis, and can step back when they want to discontinue the service.

Decreased Development and Deployment Time: Easily replicable, pre-installed applications allow developers to minimize routine coding, which significantly reduces time to deployment. Application instances can be quickly deployed expeditiously, and can be reviewed in a real-time. Boosts Focused Approach: With PaaS, businesses are not required to purchase hardware or need to possess technical expertise to manage it, which helps them to focus on application development. Greater Flexibility: PaaS enables businesses to have control over the tools and customize a platform that meets their specific requirements. Also, it allows users to pick and choose the features they consider necessary for developing an application. Fosters Innovation and Collaboration: PaaS platform has an extensive library of images, which help developers to focus on innovative solutions. With just internet connection, developers across various locations can work together on the same application build.

3. Software-as-a-Service (SaaS): Accelerating Business Growth

Software-as-a-Service is a cloud computing delivery model wherein applications are centrally hosted and managed by a service provider or vendor and made available to the users over a network.

How Businesses Can Benefit from SaaS? The popularity of SaaS is progressively increasing because it streamlines deployment process and reduces down overall customer acquisition costs. Here are some of the potential benefits that are appealing businesses: Lower Initial Costs - SaaS applications are basically subscription-based; hence no license fees need to be paid by the user. Everything is proficiently managed by the SaaS vendor, which means reduced IT costs for hardware, software, and the human resource needed to manage it completely. Easier Upgrades - SaaS vendors are completely responsible for the upgrade process. New versions and feature improvements are deployed to the hosted applications. No client applications on enduser desktops are upgraded. SaaS vendors usually offer two to four foremost upgrades per year together with other updates that the user gets routinely.

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

Instant Integration - Through multi-tenant architectures, SaaS service providers can seamlessly scale to meet customer varying demand. They also offer customized capabilities to match the specific needs of the businesses. Plus, many even provide APIs that let users seamlessly integrate with existing ERP systems or other related business productivity systems. Time-to-Market - SaaS vendors receipt charge for providing the software, hardware and network infrastructure at the data center. Apart from this, SaaS applications are generally have the scope of partial customization for features. As a conclusion, there will be zero interruption and that generates the requirement for in-house IT organizations and it helps for performing and develops, enhance and deploy applications. Easy Up-gradation - SaaS vendors monitor and maintain the upgrade process. Increasing features and new releases are positioned centrally for the applications to be hosted. End-user desktops and client applications are not required to be upgraded. Generally SaaS vendors upgrade applications two to four times annually along with numerous minor updates. User can get these updates automatically. SaaS-based applications users can avail and use the latest version of the software provided by the vendor.

4. Now everything will be available as AaaS ‘Analytics as a Service’ or ‘AaaS’ fundamentally helps an enterprise to make substantial in cost savings as well as conserve critical business time. Such central resources are strategically diverted towards data analysis within enterprises. This examination need not necessarily involve a blackbox approach; that is why white-box analysis is always recommended.

Private Cloud Computing Platform within an

Enterprise-Level Firewall

Figure 1. DESIGN OF PRIVATE CLOUD

Let us now have a deeper look at the various skins of a private cloud. As briefed above, implementation of this cloud service aims at the elimination of numerous cloud computing security issues. This is because private cloud setups are executed safely to cut down upon potential risks of data loss during calamities and natural disasters. It thus delivers efficient control over crucial business data and also safeguards security in the long run. For the records, a private cloud model is same as any traditional cluster of discrete local access networks (LANs). So it renders virtualisation to an enterprise. Features and Benefits  It makes use of techniques such as individual pools of resources that allow restricted access behind an organisation’s firewall. Additionally onsite internal hosting and dedicated leased lines ensure that user operations stay discrete.  Since it is accessed by a single organisation, configuration and management are tailored to suit a network solution well.  Improved allocation of resources leads to the availability of resources in all the individual branches/business functions. So all users can directly and flexibly respond to business related demands as well as efficiently use computing resources as compared to traditional LANs. This ultimately reduces an organisation’s carbon footprint.

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

 Resources such as servers and networks are internally hosted through virtualised operating environments. So the network automatically becomes more resilient to individual failures in physical infrastructures.  Employment of cloud bursting in a private cloud allows the service provider to change nonsensitive functions. This leads to the freeing up of space in the private cloud; sensitive functions can utilise this memory.  Together with public cloud services, well-integrated hybrid clouds can be formed.

Figure 2. KEY BENEFITS

These are a few major reasons why companies across the globe have been initiating private cloud projects. That is why the IT infrastructure today is more capable and well-adapted. Thus businesses are able to evolve at a faster pace and requirements are met within a stipulated time frame. By now it is evident that private cloud computing is inexpensive, fast and eco-friendly. So any business that opts for this service can avail its benefits without indulging into a substantial

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

infrastructure investment. Besides this, a firm gets to leverage the power of up-to-date software and vast computing resources within very little time. Further on, it renders pay-as-you-go benefits that eventually promises reduction in the number and cost of setting up gigantic data centres. Thus cloud computing guarantees low up-front costs and also results in fewer management hassles

III. Hybrid Cloud A hybrid cloud is a virtualized computing model that allows an organization to store and manage their mission critical data in-house and less significant data externally. To be precise, hybrid cloud is a combination of two or more types of cloud (private, public or community) that exhibit variation in features but are composed together, offering the benefits of several deployment models. This cloud computing model is capable of connecting to collocation, managed and/or dedicated services with cloud resources.

For instance, an enterprise migrating its IT infrastructure to hybrid cloud can benefit from scalability and cost-effectiveness because of the integration of public cloud computing model in this approach. The storage and management of mission-critical applications and data in hybrid cloud is so secure that no third party vulnerability is reported.

How Hybrid Cloud Works The hybrid cloud contains two elements: Cloud File Server and Local Cloud. Local cloud is connected to on-premise storage (computer hard drive, network-attached storage, virtual appliance running on unified storage) to integrate files and cloud file server allows users to access those files anytime, anywhere at blazing speed. Mobile access and greater file sharing capabilities

Website: www.cloudoye.com / Toll Free: 18002122022 / Mail Us: sales@cloudoye.com

are main attributes of this cloud computing model that can meet the needs of organizations, irrespective of size and business nature.

Features and Benefits  Existence of scalability increases the need for hybrid cloud as companies are capable of increasing or decreasing the bandwidth of servers in compliance with their needs. If your inhouse server fail to accommodate heavy projects, they can be shifted to another cloud platform, saving the extra cost of purchasing exclusive server hardware.  Remote access to mission-critical applications and data allows businesses to capture the global market at the least time possible. Also, this technology maintains uptime network connectivity, enabling you to run applications, share files and access data even in case of outages.  This cloud model is highly cost-effective, ensuring companies to reap the benefit of reduced operational costs, minimized upfront investment in deploying software or integrating hardware, and concentrating on core competencies instead of managing and maintaining IT infrastructure.

Who is using ‘Cloud’? Few years back will be recalled as years when cloud was emerged as a technology to replace traditional data storage and accessibility infrastructure. Now it seems that cloud computing is entering every boardroom and bedroom, with greater use of cloud services for business-critical applications.

Cloud Computing: The Widely Adopted Concept Rapid rise in the number of cloud adopters has overshadowed a few notable security concerns of cloud computing (mainly related to consumers and these included data tampering of the PlayStation Network in 2011), with big players like Apple, Amazon, Google and Microsoft have already allowed enterprises and individuals to reap the benefits of this avant-garde technology.

The Cloud is used more by larger businesses

Meanwhile, Google, Microsoft and Amazon have also joined the league for delivering best in class cloud services. For instance, Google’s Cloud Storage and App Engine tools, Microsoft’s Office 365 Suite and Amazon’s Kindle demonstrate the potential of cloud in both business and pleasure. The time is suitable for organizations to reap the benefits of consolidation, virtualization and automation, which are the striking features of cloud computing that many industry players reckon. “Predecessors of cloud computing didn’t take off because the user experience was not there and the management tools were not fantastic,” says CK Lam, Enterprise Solutions Manager, Asia Pacific of Juniper Networks (Link). “Now I am convinced that it will take off. The economic advantage is just huge.” Though, the percentage of cloud adoption among large companies is higher as compared to medium and small-sized firms, but its service keeps on growing, encouraging corporations, small businesses, families, commuters, gamers and everyone in between to take the advantage of virtualization.

Why Should You Move to ‘Cloud’? Cloud computing boasts about the way in which it has paved way for aparadigm transition in the evolution of IT. Notable benefits such as lower costs, greater agility and better resource utilization have increased the rate of adoption. Meanwhile, Software-as-a-Service (SaaS), Infrastructure-as-aService (IaaS) and Platform-as-a-Service (PaaS) models of cloud enable organizations to derive insights for better business decisions.

Letâ&#x20AC;&#x2122;s take a more detailed look on why moving to cloud is beneficial for enterprises without regard to size and nature of business: Greater Flexibility: The cloud-based services are capable of promptly meet business demands because of scalable in nature. Of late, organizations focus not just on saving money, but they also give priority to scale up their operations as soon as their businesses demand, and scale down just as quickly if resources are futile. Easy and Quick to Deploy Applications: Installation, configuration and running of applications of any size is simple and fast in cloud environment. Creating and removing platforms for new applications is done at a great speed, allowing your human resource to focus more on their core expertise to improve the revenue of your organization. Disaster Recovery: When companies migrating to cloud, they neednâ&#x20AC;&#x2122;t to worry for data loss or data theft. This is because disaster recovery plan of cloud-based service is designed keeping in the mind the significance of applications and data and both can be restored much faster if lost. A research study reveals that companies using cloud have the ability to address issues in an average of 2.1 hours, nearly four times quicker than those still relying traditional server infrastructure (8 hours).

Reduced Head Count: With fewer servers to maintain in a virtualized, automated environment, you will realize that you need fewer IT staff. In fact, enterprises using cloud start reducing the headcount of IT department by nearly 50%. Free from Capital Expenditure: All service models of cloud computing allow users to pay for services they actually use. In fact, pay-as-you-go concept exists in cloud computing and as a result, there is no need for capital expenditure at all. Work from Anywhere: As cited, virtualization is the striking feature of cloud-based service, running and accessing mission-critical applications from anywhere is possible provided that the user’s web-enabled or mobile device is connected with the Internet. The aforesaid points clearly indicate that companies, intending to slash IT infrastructure and staffing costs without affecting the performance of their productivity, tend to move to cloud in order for leveraging their existing IT environment.

Cloud Security and Risks Cloud computing is gaining traction with businesses, but before you decide to jump into the cloud, you should know about some of the key security risks it triggers. It has matchless attributes that do entail risk analysis and management in areas, such as data integrity, recovery, and confidentiality, and an assessment of legitimate concerns in areas, such as e-discovery, monitoring, and appraising. Moreover, the line-of-business users are now at a faster pace creating applications and moving their mission critical data to the cloud without understanding all the security implications. Let’s have a closer look at some of the perceived security risk in cloud computing and how these risks can be mitigated to develop a secure and holistic IT infrastructure.

Key security risk concerns related to cloud: Data breaches: Online data breaches lead to the loss of personal and credit card information of individuals is one of a series of staggering thefts that usually take place at the time of normal online transaction and data storage. Cloud computing has substantially introduced new possibilities of attack. The extensive security of hypervisor and VM operations is still under a big question mark. A cloud basically constitutes of business critical applications and data, and if any invader penetrates far enough, then no one knows how many sensitive pieces of information will be exposed. Besides this, if a multi-tenant cloud service database is not appropriately intended, a snag in one user’s application could let an invader access not onl y to that user’s data, but every other user’s data also. Integration of encryption key do protects data at rest, but you are liable to lose your data in case you lose of the encryption key unexpectedly.

Data Loss: Data loss may occur unexpectedly through data corruption, deletion (human error), and theft or hardware failure. Plus, when the owner of encrypted data forgets or mislays the key that unlocks it. Irrefutably, the thought of losing one's data permanently is terrifying for both individuals and businesses. However, there are numerous techniques to thwart such type of data loss.

Leading causes of Data Loss

Account or Service Traffic Hijacking: Account or service traffic hijacking may appear to be elementary term, but it has been one of the major concerns related to the cloud security. Phishing and corruption of software susceptibilities, such as buffer overflow outbreaks, and loss of passwords and credentials can all bring about the loss of control over the key user account. An intruder with access over a user account can snoop into the transactions, manipulate data, provide made-up and business-destructive responses to the prospective customers, and redirect customers to either to a competitor's site or incongruous sites.

Insecure Interface and APIs: The cloud era has brought forth the paradox of trying to make services accessible to millions while regulating any damage that these surreptitious users can do the service. Basically, API keys are used by web and cloud services to recognize third-party application using the services. If the cloud vendor isnâ&#x20AC;&#x2122;t watchful, chances are that the attacker might break in and cause harm to the critical data of the company.

The best way to mitigate cloud security risks is to develop a highly secure infrastructure- one that covers both physical and virtual computing systems no matter where they are housed, and no matter where data is stored.
