A Brief overview of Cloud hosting
Introduction
The term Cloud hosting means, the process of operating a website on multiple servers. There is an unlimited processing power in cloud hosting as we can always add a new server to scale up. The cloud hosting technology has lots of benefits. Cloud computing Hosting is the provision of computational resources like data and software on-demand through a computer network, and not from one local computer. In this type of computing, the clients submit a task, for e.g. word processing, to the cloud computing service provider. The clients can get their task completed without possessing the software or hardware.
Benefits
The most important benefits are its scalability and cost effectiveness. Scalability refers to the expansion of the website with minimum limitations. The cloud server hosting covers load balancing and hardware upgrades etc. Cloud hosting can avoid the problems like server crash and migration of a website from shared server to a dedicated server. The cost of this web hosting services is decreasing day by day. Some other benefits include Application Programming Interface (API) accessibility to software. The API enables machines to interact with cloud software and done in the same way the user interface helps humans to interact with the computers. This service enables the users to access their systems on web irrespective of their location and thus provides location independence.
Applications
These procedures can be applied for management of commercially available software and network access to it. Disaster management and data retrieving are also facilitated by cloud computing hosting.
Services
Cloud Hosting services are provided by certain companies which charge their clients based on the quality of the computing power used by them just like the electricity and water bills. Business firms engaged in cloud hosting in India offers professional and efficient services at a price best suited in the industry.
Disadvantages
There are a few disadvantages of the cloud hosting. The first disadvantage is that you will not have a control over the physical location of your data during the hosting. Another problematic issue is that you are not sure about the safety of your data as you share the physical hardware with other users. Safety is the major issue of the two.
The cloud hosting services in India are rapidly gaining popularity as it has achieved a growth from a business concept to a sparkling sector of IT. The best solution of IT is the one of the best cloud computing and hosting service providing companies in India. This company is committed towards achieving the maximum client satisfaction and has a trained staff for doing the not so easy job of cloud computing and hosting.
General Concepts about Object-Oriented Programming
The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.
Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.
An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:
– they provide a better understanding of the problem to be solved;
– they provide a base design for implementation.
A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.
Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.
Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.
In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.
There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.
How Does Penetration Testing Work?
In the digital age, data can be as valuable as physical assets. Every year, companies spend hundreds of millions of dollars on hardware and software to protect the data located on their computers. A single security breach could mean having trade secrets compromised or customer information in the wrong hands. Passwords, firewalls and encryption are valuable tools in the ongoing battle against those who would attempt to bypass a company’s network security.
Once all of the components of a proper security system are in place, it is proper procedure to run a final test. This test is referred to as penetration testing. The cyberspace version of a military unit conducting war games, the test is an effort to compromise the newly installed security. A thorough test is the best way to reduce the risk of a security breach at the hands of a real threat.
The first step in the process is risk assessment. This is the practice of determining exactly what is at stake. By finding out exactly where vulnerabilities lie, a better picture can be formed as to exactly what a would-be information thief would be after. For instance, if an online retailer has a large database containing sensitive customer information such as credit card numbers or bank information, they can identify those assets as being a huge liability if compromised, as well as a prime target for hackers. Anther example of a potential liability is a company that has gone through great lengths to assemble a list of leads or clients. These kinds of assets are particularly appealing to unscrupulous competitors or hackers intent on blackmail.
After areas of vulnerability are determined, the penetration test can commence. Generally, the first systems tested are those that can be accessed from the outside. Websites, email access points and remote access platforms are the most frequent gateways for security breaches, and as such are the subject of the most intense tests.
In order to conduct a proper test, a security company must not only be familiar with the most current techniques and tools available to hackers and cyber criminals, they must also have the ability to foresee potential methods of bypassing security systems. This will keep a company’s computer system defense one step ahead of those who would wish to do harm. A solid penetration test is the last, and perhaps most important step, in being protected against important data being lost or stolen.
