This method is more used for intra-business interactions. Where the computing resources can be governed, owned and operated by the same organization. Community Cloud: Here, computing resources are provided for a community and organizations. Here the computing resource is owned, governed and operated by government, an academic or business organization.
This deployment method is called hybrid cloud as the computing resources are bound together by different clouds. SaaS Software as a Service SaaS or software as a service is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network internet.
Through internet this service is available to users anywhere in the world. SaaS users on the other hand, instead of purchasing the software subscribes to it, usually on monthly basisvia internet.
Anyone who needs an access to a particular piece of software can be subscribe as a user, whether it is one or two people or every thousands of employees in a corporation.
SaaS is compatible with all internet enabled devices. Many important tasks like accounting, sales, invoicing and planning all can be performed using SaaS.
PaaS Platform as a Service Platform as a service, is referred as PaaS, it provides a platform and environment to allow developers to build applications and services. This service is hosted in the cloud and accessed by the users via internet.
To understand in a simple terms, let compare this with painting a picture, where you are provided with paint colors, different paint brushes and paper by your school teacher and you just have to draw a beautiful picture using those tools.
Software developers, web developers and business can benefit from PaaS. It provides platform to support application development. It includes software support and management services, storage, networking, deploying, testing, collaborating, hosting and maintaining applications. It provides computing infrastructure like virtual server space, network connections, bandwidth, load balancers and IP addresses.
The pool of hardware resource is extracted from multiple servers and networks usually distributed across numerous data centers. This provides redundancy and reliability to IaaS.
For small scale businesses who are looking for cutting cost on IT infrastructure, IaaS is one of the solutions. Annually a lot of money is spent in maintenance and buying new components like hard-drives, network connections, external storage device etc. What is Cloud Computing Architecture?
Cloud computing comprises of two components front end and back end. Front end consist client part of cloud computing system. It comprise of interfaces and applications that are required to access the cloud computing platform. While back end refers to the cloud itself, it comprises of the resources that are required for cloud computing services. For example, a company engaging in computer forensics might use the information collected to make policy changes or to institute stronger network security.
Computer forensics teams might encounter a number of issues. Encrypted data on a computer might be impossible to access without a password. In this situation, a team may need to use special acquisition techniques.
Adequate processing power may be necessary to examine large storage devices for computers. With new developments in computer software and hardware, computer forensics must continually evolve to match new technology. Testing and experimentation may be necessary in these situations. Some people may utilize anti-forensics tactics to keep investigators from accessing data. Encryption, overwriting data, modifying metadata, and disguising files are examples of anti-forensics tactics.
Legal issues may also arise. A computer owner may devise a legal defense designed to create a distraction from the findings. Various administrative issues could also affect how groups accept findings from a computer forensic investigation.

Explore some of the processes performed by computer forensics experts as they extract and collect data from a computer. IT Hare on Soft. Uses of Computer Forensics Computer forensics has a variety of applications. Hacking involves a modification of a computer or a mobile device to change it from its original intent or purpose. A hacker might hack a system maliciously, or people might hack their own devices to change how they operate. Metadata is simply data about other data.
Files may contain metadata, or this data could be located in a separate file elsewhere. Metadata usually includes the creation date of the data, its format, and its author.
