Security Issue On Hybrid Cloud Computing

As previously mentioned, cloud computing has recently emerged as a pioneering model for hosting and distributing services over the Internet. Actually, the model entails sharing resources on a huge scale through a value effective and location independent process. While the resources on the cloud are deployed by the seller, they are utilized by the consumer (Belamkar, 2014). Cloud computing is very beneficial to organizations and companies because it is engaging to business organizations

The advantages of a public or hybrid cloud include allowing an organization to utilize applications

Business owners use three types of cloud service, public, private, and hybrid these clouds store their data and provide them with services. The benefits of these clouds are endless, additionally, they saves businesses time and money, promoting innovation, enhancing productivity, and improving communication while cloud hosting accelerate information sharing, like email, application hosting, web-based phone, and data storage (Griffith, 2013).

Everyone has an opinion on what is cloud computing. It can be the ability to rent a server or a thousand servers. It can be the ability to rent a virtual server, load software on it, turn it on and off at will. It can be storing and securing large amounts of data that is accessible only by authorized applications and users.

According to Bowen (2011), there are four models for deploying cloud services (p1). A private cloud is private. Meaning it is yours and operated only for you. However, the private cloud can be outsourced to be managed by another. As the owner of the private cloud you can dictate your security and privacy options yourself. A community cloud is shared with others. By working with a community, the consumers should have shared requirements, security, and privacy options. Another type of cloud is the public cloud. This type of cloud is open to the public or it could be a large consumer who owns the cloud and is offering the services to consumers for a price. The last type of cloud is the hybrid. A hybrid cloud can both be private and community. The clouds are tied together but are still separate. The clouds share data and application portability.

Cloud computing is unlike traditional hosting alternatives that use a single dedicated server, as cloud computing uses virtualization technology to pool or share resources from an underlying network of physical servers. In other words, a group of physical servers acts like one big server to bring you the resources that you need on demand. Cloud computing delivers shared computing resources, data or software through the Internet; which is the most common way of accessing the cloud. However, intranets and dedicated networks are also used too. Resources provided by the cloud include: networks, servers, storage, platforms, applications and other services. And these resources are shared between people and organizations, and accessed by applications or users.

Cloud computing is computing and software resources available on demand, as a service. Computing tasks, Running Applications or storing data can be three broad categories of activities of cloud computing. There are mainly three types of services; Software-as-a-service, Platform-as-a-service and Infrastructure-as-a-service. There are four key deployment models, private, public, hybrid and community cloud. Cloud has few key characteristics like being cost effective, rapidly elastic, segueing into plethora of opportunities and innovations, resource pooling and available on-demand along with providing advanced security. Cloud computing has many advantages like being economical, quite

Cloud computing an evolving term that describes the event of the many existing technologies and approaches to computing into one thing totally different. Cloud separates application and therefore the resources with info from the underlying infrastructure, and therefore the mechanisms wont to deliver them. Cloud enhances collaboration, agility, scaling, and availableness that provides the potential for price reduction through reduced and economical computing. The word Cloud describes the employment of assortment of services, info, infrastructure comprised of pools of network, info, and storage resources. These elements are often quickly organized, provisioned, enforced and decommissioned, and

A hybrid cloud system, as the name suggests, combines both the public and private cloud servers models into one integrated system. For example, a company may choose to host some more sensitive types

It is a dedicated storage. In public cloud, many users can share the storage but in private cloud only independent organizations so this is the difference between public and private cloud. The last and the third one is Hybrid cloud. If any organizations use public plus private cloud then it comes under hybrid cloud. Hybrid cloud combines the elements of both private and public cloud for non sensitive operations and private setup for sensitive operations. Example of hybrid cloud is Dropbox. Dropbox is a hybrid service that provide synced version of your files online but a copy is stored on your local system as well. Cloud services models are divided into three services : Infrastructure as a services , platform as a services , software as a services It is helpful to start thinking about managing your own software and your own data on your own servers on premises and if that’s what you are doing you are responsible for the entire things. You know all the way down to the cooling and the power and in the server rooms , the networking , the cable , and the fiber that is running through the walls , if you are virtualizing what is your virtualization layer , what operating systems are you running , what languages and platform , all the way up to the data and the applications itself. That is all your responsibility; you have to manage all this entire things. Infrastructure as service helps you to beware of some of the strains like storage,

An example of Public cloud: Microsoft Azure. Example Public Cloud Providers: Google and Amazon. One plus about a public cloud is under-utilization is eliminated because customers are only charged for what they are using. A private cloud type is defined as internal services of an organization or third party that is not accepted by the public user. Example: Eucalyptus. As stated even though it might be expensive compared to a public cloud it is more secured.

The term “cloud” was coined from the computer network diagrams which use it to hide the complexity of infrastructure involved. cloud computing provides software, platform and infrastructure as a service. its main features include resource pooling, rapid elasticity, measured service, on-demand self service and broad network access. so, a cloud is a collection of hardware and software that runs in a data centre and enables the cloud computing model. A cloud reduces capital investment, hardware cost and software licence cost.

Cloud Computing is one of the emerging technologies which now represent a reality and a low-cost computing power resource which has gained popularity among all business categories, especially medium and small size, governmental or medical organizations, as more people are realizing the power and benefits of cloud environments. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Clouds can be classified as public, private or hybrid

The first advantage of cloud computing is the variety of cloud models. There are three types of deployment models used in the everyday; they are the following: public, hybrid, and private. Public cloud is accessed by anyone on the internet through web applications and services. The hybrid cloud contains many inside and outside developers used by many businesses. Lastly, the private cloud is services only offered on a private network where no one outside the network can access. This model is safer because the cloud is not open to data breaches (compared to a public cloud).

In cloud computing, services are shared over the communication network ie. Internet. In concept of cloud computing multiple computers can access services and data that is stored on the server (Cloud). So that the cost for installation the software and cost for maintenance is reduced because they do not need to be installed on each user's computer and can be accessed from different places.
