Send feedback about In addition, with applications hosted centrally, updates can be released without the need for users to install new software. One drawback of SaaS comes with storing the users' data on the cloud provider's server. As a result, [ citation needed ] there could be unauthorized access to the data. In the mobile "backend" as a service m model, also known as backend as a service BaaS , web app and mobile app developers are provided with a way to link their applications to cloud storage and cloud computing services with application programming interfaces APIs exposed to their applications and custom software development kits SDKs.
Services include user management, push notifications , integration with social networking services  and more. This is a relatively recent model in cloud computing,  with most BaaS startups dating from or later    but trends indicate that these services are gaining significant mainstream traction with enterprise consumers. Serverless computing is a cloud computing code execution model in which the cloud provider fully manages starting and stopping virtual machines as necessary to serve requests, and requests are billed by an abstract measure of the resources required to satisfy the request, rather than per virtual machine, per hour.
Function as a service FaaS is a service-hosted remote procedure call that leverages serverless computing to enable the deployment of individual functions in the cloud that run in response to events. Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third party, and hosted either internally or externally. It can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. Self-run data centers  are generally capital intensive. They have a significant physical footprint, requiring allocations of space, hardware, and environmental controls.
These assets have to be refreshed periodically, resulting in additional capital expenditures. They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from less hands-on management,  essentially "[lacking] the economic model that makes cloud computing such an intriguing concept".
A cloud is called a "public cloud" when the services are rendered over a network that is open for public use. Public cloud services may be free. Hybrid cloud is a composition of a public cloud and a private environment, such as a private cloud or on-premise resources,    that remain distinct entities but are bound together, offering the benefits of multiple deployment models.
It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service. Varied use cases for hybrid cloud composition exist. For example, an organization may store sensitive client data in house on a private cloud application, but interconnect that application to a business intelligence application provided on a public cloud as a software service. Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses.
Another example of hybrid cloud is one where IT organizations use public cloud computing resources to meet temporary capacity needs that can not be met by the private cloud. A primary advantage of cloud bursting and a hybrid cloud model is that an organization pays for extra compute resources only when they are needed. A cross-platform hybrid cloud is usually powered by different CPU architectures, for example, x and ARM, underneath. Users can transparently deploy and scale applications without knowledge of the cloud's hardware diversity.
Community cloud shares infrastructure between several organizations from a specific community with common concerns security, compliance, jurisdiction, etc. The costs are spread over fewer users than a public cloud but more than a private cloud , so only some of the cost savings potential of cloud computing are realized. A cloud computing platform can be assembled from a distributed set of machines in different locations, connected to a single network or hub service.
It is possible to distinguish between two types of distributed clouds: public-resource computing and volunteer cloud. Multicloud is the use of multiple cloud computing services in a single heterogeneous architecture to reduce reliance on single vendors, increase flexibility through choice, mitigate against disasters, etc. It differs from hybrid cloud in that it refers to multiple cloud services, rather than multiple deployment modes public, private, legacy.
The issues of transferring large amounts of data to the cloud as well as data security once the data is in the cloud initially hampered adoption of cloud for big data , but now that much data originates in the cloud and with the advent of bare-metal servers , the cloud has become  a solution for use cases including business analytics and geospatial analysis.
HPC cloud refers to the use of cloud computing services and infrastructure to execute high-performance computing HPC applications. Cloud architecture ,  the systems architecture of the software systems involved in the delivery of cloud computing, typically involves multiple cloud components communicating with each other over a loose coupling mechanism such as a messaging queue.
Elastic provision implies intelligence in the use of tight or loose coupling as applied to mechanisms such as these and others. Cloud engineering is the application of engineering disciplines to cloud computing.

It brings a systematic approach to the high-level concerns of commercialization, standardization, and governance in conceiving, developing, operating and maintaining cloud computing systems. It is a multidisciplinary method encompassing contributions from diverse areas such as systems , software , web , performance , information technology engineering , security , platform , risk , and quality engineering. Cloud computing poses privacy concerns because the service provider can access the data that is in the cloud at any time.
It could accidentally or deliberately alter or delete information.
An Overview of Issues and Recent Developments in Cloud Computing and Storage Security
That is permitted in their privacy policies, which users must agree to before they start using cloud services. Solutions to privacy include policy and legislation as well as end users' choices for how data is stored. These systems distinguish between authorized and unauthorized users and determine the amount of data that is accessible to each entity.
Together, these form shared technology vulnerabilities. In a cloud provider platform being shared by different users there may be a possibility that information belonging to different customers resides on the same data server. Additionally, Eugene Schultz , chief technology officer at Emagined Security, said that hackers are spending substantial time and effort looking for ways to penetrate the cloud. Because data from hundreds or thousands of companies can be stored on large cloud servers, hackers can theoretically gain control of huge stores of information through a single attack—a process he called "hyperjacking".
Some examples of this include the Dropbox security breach, and iCloud leak. By having these passwords, they are able to read private data as well as have this data be indexed by search engines making the information public. There is the problem of legal ownership of the data If a user stores some data in the cloud, can the cloud provider profit from it? Many Terms of Service agreements are silent on the question of ownership. This delivers great incentive to public cloud computing service providers to prioritize building and maintaining strong management of secure services.
There is the risk that end users do not understand the issues involved when signing on to a cloud service persons sometimes don't read the many pages of the terms of service agreement, and just click "Accept" without reading. This is important now that cloud computing is becoming popular and required for some services to work, for example for an intelligent personal assistant Apple's Siri or Google Now. Fundamentally, private cloud is seen as more secure with higher levels of control for the owner, however public cloud is seen to be more flexible and requires less time and money investment from the user.
According to Bruce Schneier , "The downside is that you will have limited customization options. Cloud computing is cheaper because of economics of scale , and—like any outsourced task—you tend to get what you get. A restaurant with a limited menu is cheaper than a personal chef who can cook anything you want. Fewer options at a much cheaper price: it's a feature, not a bug.
Cloud providers often decide on the management policies, which moderates what the cloud users are able to do with their deployment. Privacy and confidentiality are big concerns in some activities. For instance, sworn translators working under the stipulations of an NDA , might face problems regarding sensitive data that are not encrypted.
Cloud computing is beneficial to many enterprises; it lowers costs and allows them to focus on competence instead of on matters of IT and infrastructure. Nevertheless, cloud computing has proven to have some limitations and disadvantages, especially for smaller business operations, particularly regarding security and downtime. Technical outages are inevitable and occur sometimes when cloud service providers CSPs become overwhelmed in the process of serving their clients.
This may result to temporary business suspension. Since this technology's systems rely on the internet, an individual cannot be able to access their applications, server or data from the cloud during an outage.
About this book
Cloud computing is still a subject of research. The issue of carrying out investigations where the cloud storage devices cannot be physically accessed has generated a number of changes to the way that digital evidence is located and collected. In some scenarios existing digital forensics tools can be employed to access cloud storage as networked drives although this is a slow process generating a large amount of internet traffic.
An alternative approach is to deploy a tool that processes in the cloud itself. For organizations using Office with an 'E5' subscription there is the option to use Microsoft's built-in ediscovery resources, although these do not provide all the functionality that is typically required for a forensic process.
