Cloud Computing And Its Challenges

Hybrid cloud is a mix of both private and public from different providers that offers benefits of multiple deployment models. Extends capability of a cloud service.

The “cloud” provides rapid access to flexible and low cost IT resources; people can access as many resources as the need, almost instantly, and only pay for what they use. There are six advantages and benefits that AWS is advertising, such as pay for how much you consume; achieve higher economies of scale which translates into lower pay as you go prices; eliminate guessing on your infrastructure capacity needs; increase speed and agility; stop spending money on running and maintaining data centers; and provide lower latency and better experience for your customers simply and at minimal cost. Cloud computing has three main types that are commonly referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS contains the basic building blocks for cloud IT and typically provide access to networking features, computers, and data storage space. Also, it provides with the highest level of flexibility, and management control over your IT resources and is most similar to existing IT resources that many IT departments and developers are familiar with today. PaaS remove the need for organizations to manage the underlying infrastructure and allow you to focus on the deployment and management of your applications; this helps to be more efficient and not to worry about resource procurement, capacity planning, software

Hybrid Cloud is a combination of cloud infrastructures (public, private, or community) that remain unique but are tied together by standardized technology that enables application and data portability. Hybrid cloud is the most complicated configuration to manage and the most economical model. It combines benefits of the secured environment in private clouds and rapid elasticity of public clouds.

The cloud can be rented for use to anyone willing to pay for it. It is the cheapest type of cloud computing service but because of its public nature it is deemed to be less secure. Hybrid Cloud: It consists of multiple private and public clouds.

There are 3 different types of cloud computing: private, public and hybrid cloud. The private cloud is only used by one company, this is either used internally or it is outsourced to another company. The public cloud is when the cloud and all of its services are accessible by anyone. A Hybrid cloud is a combination of the two.

Cloud computing is moving into the mainstream. Moving to the cloud might be a viable option for some consumers. However, there are many facets to consider before moving to the cloud. There are four types of clouds, public, private, community, and hybrid. All four cloud arrangements have pros and cons, and they need to be weighed before a decision is made. Two main challenges of clouds are security and privacy. These two main issues must be addressed prior to choosing a cloud service. As a consumer, you make the choice for how stringent your security and privacy are to your stakeholders.

Technology is changing rapidly. Businesses have appreciated the use of modern technologies to do various activities. When businesses are using different types of technology, they want to make sure that they have everything they need. You will realize that cloud solutions is one of these options that they are going to consider. There are 3 different types of cloud solutions that businesses can choose from. These include: private cloud, hybrid cloud and public cloud.

of organization, are discussed. Characteristics of cloud computing discussed to get idea what the cloud computing is all about using. In addition to that, deployment model of cloud computing is discussed in greater detail to explain cloud computing can be used as public, private or hybrid type. Based on service delivery cloud computing divided into three types Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are explained further in this section.

There is wide range of services that could be provided by cloud providers. Based on blabla, there are 3 models of cloud services that widely popular. They are Infratructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides for fundamental resource for computing such as processing, servers, storage, networks and manage its physical infrastructures but costumers have control for their OS [fn1]. PaaS provides design, tools or Environment with IDE. It is usually used by software developer who wants to run their application over internet. SaaS delivers ready-use software over internet or we can called as web-based software. Cloud users neither have to maintain platform or infrastructures. These days this services gain money from advertising or user list sales for example Google mail service so users can enjoy it free.

Cloud technology innovation is emerging as one of the most popular issue for most IT practitioners and cloud computing is thought of as the future trend of development of the IT industry. According to Stanoevska (2010), enterprises should have an IT infrastructure that can reform itself rapidly to new business priorities. Cloud computing technologies, such as Cloud mail, Cloud platform and Cloud software services, provide an efficient work platform for enterprises. At the same time, Carling (2011) puts forward potential problematic issues in terms of the security of cloud computing. The future of enterprise cloud computing becomes increasingly controversial. Nevertheless, enterprises should base their future framework for Information and

There are different types of cloud computing services available on the market which falls into one of the following categories.

Public cloud/outer cloud: This model permits cloud environment as straightforwardly or publically available. Open cloud is off reason in which different endeavors can be utilized to convey the administrations to clients by taking it from outsider. Private cloud/inside cloud: This model alluded to on-reason cloud, which is overseen or claimed by an association to give the abnormal state control over cloud administrations and base. At the end of the day private cloud is assemble particularly to give the administrations inside of an association for keeping up the security and protection. Hybrid cloud/virtual private cloud demonstrate: This model traded off both private and open cloud models where distributed computing environment is facilitated and oversaw by third get-together (off-reason) however some committed assets are secretly utilized just by an association. Community model: It permits the distributed computing environment, which is shared or oversaw by number of related associations.

1.Cloud Computing: Cloud computing is defined as the different services such as service, storage and applications are deliver to organization devices and computers through internet. There are mainly three types of clouds they are private public and hybrid and three services are offered by the cloud mainly Software as a service in which user rent access to software application functionally over the internet eg:ltu student mails .,

There are three main types of cloud-computing services: (1) Infrastructure as a Service (IaaS), (2)

With the rapid change in processing and storage technologies and the success in the communication network such as Internet, lessen cost of computing resources, more powerful and more ubiquitously available than ever before. This technological change has enabled the development of a new computing paradigm called cloud computing, in which resources are shared by multiple system over the communication network. Cloud computing is a set of IT services that are provided to a business organizations or customers over a network on a leased basis and with the ability to scale up or down their service requirements. Cloud computing services are delivered by a third party provider who owns the infrastructure. Cloud computing has turned up as a new model for hosting and delivering services over the internet. Cloud computing becomes an attraction in the business world as it does not require plan for provision and business can be set up with a small amount.
