What is Shared Web Hosting Service?

Shared web hosting service refers to a web hosting service where many websites reside on one web server connected to the Internet. This is generally the most economical option for hosting, as the overall cost of server maintenance is amortized over many customers.

The hosting service must include system administration since it is shared by many users; this is a benefit for users who do not want to deal with it, but a hindrance to power users who want more control. In general shared hosting will be inappropriate for users who require extensive software development outside what the hosting provider supports. Almost all applications intended to be on a standard web server work fine with a shared web hosting service. But on the other hand, shared hosting is cheaper than other types of hosting such as dedicated server hosting. Shared hosting usually has usage limits and hosting providers should have extensive reliability features in place.

Shared hosting services typically offer…

Common Questions and Answers about Cloud Computing

How does cloud computing provides on-demand functionality?, What do I need to do to get ready for the cloud?, What can be outsourced to the cloud?, How much will it cost?,... are common Cloud Computing questions and answers.
How much will it cost?
As with any other technology issue, the answer to this one is: it depends. The first step is to determine all the potential costs, so ask cloud providers for a list of every possible expense that could crop up. Common expenses include data-storage costs; one-time fees for moving data; uploads and downloads; general network bandwidth fees; and maintenance costs. Fortunately, most cloud providers will give you a free quote and work with you on pricing, making it easier to compare providers.

How does cloud computing provides on-demand functionality?
Cloud computing is a metaphor used for internet. It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you. It provides an easy way to provide …

Most common uses of Cloud Computing

Cloud computing has been credited with increasing competitiveness through cost reduction, greater flexibility, elasticity and optimal resource utilization. Here are most common uses of cloud computing.
Private cloud & hybrid cloud
Among the many incentives for using cloud, there are two situations where organizations are looking into ways to assess some of the applications they intend to deploy into their environment through the use of a cloud. While in the case of test and development it may be limited in time, adopting a hybrid cloud approach allows for testing application workloads, therefore providing the comfort of an environment without the initial investment that might have been rendered useless should the workload testing fail.

Another use of hybrid cloud is also the ability to expand during periods of limited peak usage, which is often preferable to hosting a large infrastructure that might seldom be of use. An organization would seek to have the additional capacit…

What is Public Cloud Service?

A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.

Benefits of using a public cloud service:

Easy and inexpensive set-up because hardware, application and bandwidth costs are covered by the provider.Scalability to meet needs.No wasted resources because you pay for what you use. The term "public cloud" arose to differentiate between the standard model and the private cloud, which is a proprietary network or data center that uses cloud computing technologies, such as virtualization. A private cloud is managed by the organization it serves. A third model, the hybrid cloud, is maintained by both internal and external providers.

12 reasons why public clouds are better than private clouds

Private clouds tend to use older technology than public clouds: You may h…

Protecting Your Personal Data in the Cloud

How can you be sure the information you store on the cloud is safe? The short answer is you can't. However, you can take some protective measures.

Here are some data privacy protection tips to help you tackle the issue of cloud privacy.

Perform regular data backups.
No matter how reliable the cloud might seem it’s always a good idea to back up your data somewhere else. At the very least, regular backups ensure that your valuable data won’t be permanently lost in the event of a data breach or other data theft incident.

Use cloud services that encrypt your data by default.
Different cloud service providers offer different options for data storage and handling. Finding a cloud storage service that provides automatic data encryption means that anything you share or store with that provider will be safe. This is a good option for users that want to encrypt all of their data in the cloud as opposed to encrypting on a case-by-case basis.

Encrypt sensitive data.
Encryption is one o…

How to Choose the right Cloud hosting services

The cloud provides an alternative way of procuring IT services that offers many benefits, including increased flexibility as well as reduced cost. It extends the spectrum of IT service delivery models beyond managed and hosted services to a form that is packaged and commoditised. 

However, in a recent survey by global IT association ISACA, 30% of the 3,700 respondents said cloud computing is one of the top issues expected to impact their enterprise’s security in the next 12 months. Clearly, a good understanding of cloud is critical, as is effective governance over the cloud.

The cloud is not one thing; it covers a wide spectrum of types of service and delivery models, ranging from in-house virtual servers to software accessed by multiple organisations over the internet.

It is important to understand the variety of cloud services and deployment models to choose the one most suitable for your needs.

How to select the right type of cloud service

How to select the right type of cloud service:

Infrastructure-as-a-service (IaaS) provides basic computing resources that the customer can use to run software (both operating systems and applications) and to store data. IaaS allows the customer to transfer an existing workload to the cloud with minimal, if any, change needed.

The customer does not manage or control the underlying cloud infrastructure, but remains responsible for managing the OS and applications. IaaS removes the need to buy, house and maintain the physical servers and can provide the ability for an organisation to respond quickly to changing demand.

Platform-as-a-service (PaaS) provides an environment upon which the customer can use to build and deploy cloud applications. These applications may be for use by the customer or offered as a service to others. Building applications using PaaS means that they are inherently cloud-enabled and the PaaS provider also provides the service upon which these applications…

How to make a successful website

A lot of internet users have built websites, spent time on development and devoted a lot of effort to increase their popularity. However, a relatively small percentage of those webmasters have really succeeded in creating highly ranking "megasites" like Google, Yahoo, Facebook and so on. A good website is not only about text and images, it is a creative project that requires a lot of attention and numerous skills from a wide variety of specialists who work towards a common goal...

Here are some of the steps to makes a successful website:

1. Work hard and devote a lot of time. 
If you really want to make a successful website then be prepared to sacrifice a lot of time and effort towards your goal. We cannot stress enough the importance of dedicating yourself to the website. Most people who earn their living from their sites spend more than 8 hours every day writing articles, adding new content and improving their visitor experience. This is why you should always ta…

What is Hybrid Cloud?

The hybrid cloud is the combination of a public cloud provider (such as Amazon Web Services, Google Cloud,...) with a private cloud platform one that's designed for use by a single organization. The public and private cloud infrastructures, which operate independently of each other, communicate over an encrypted connection, using technology that allows for the portability of data and applications.
A hybrid cloud is an integrated cloud service utilising both private and public clouds to perform distinct functions within the same organisation. All cloud computing services should offer certain efficiencies to differing degrees but public cloud services are likely to be more cost efficient and scalable than private clouds. Therefore, an organisation can maximise their efficiencies by employing public cloud services for all non-sensitive operations, only relying on a private cloud where they require it and ensuring that all of their platforms are seamlessly integrated.

Layers of Cloud Computing

Cloud computing is made up of a variety of layered elements, starting at the most basic physical layer of storage and server infrastructure and working up through the application and network layers. The cloud can be further divided into different implementation models based on whether it's created internally, outsourced or a combination of the two.
3 cloud layers are:

Infrastructure cloud: Abstracts applications from servers and servers from storageContent cloud: Abstracts data from applicationsInformation cloud: Abstracts access from clients to data
3 cloud implementation models are:

Private cloud: Created and run internally by an organization or purchased and stored within the organization and run by a third partyHybrid cloud: Outsources some but not all elements either internally or externallyPublic cloud: No physical infrastructure locally, all access to data and applications is externalAn infrastructure cloud includes the physical components that run applications and store …

What is Cloud Computing?

Cloud computing is a general term for the delivery of hosted services over the Internet.

Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers. It relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.

Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand. This can work for allocating resources to users. For example, a cloud computer facility that serves European users during European business hours with a specific application (e.g., email) may reallocate the same resources to serve North Ameri…

What is a Private Cloud?

Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to a single organization.
What is a Private Cloud?

A private cloud is a particular model of cloud computing that involves a distinct and secure cloud based environment in which only the specified client can operate. As with other cloud models, private clouds will provide computing power as a service within a virtualised environment using an underlying pool of physical computing resource. However, under the private cloud model, the cloud (the pool of resource) is only accessible by a single organisation providing that organisation with greater control and privacy.

The technical mechanisms used to provide the different services which can be classed as being private cloud services can vary considerably and so i…

Tips For Cloud Computing Security

Cloud Computing is the new buzzword. It has many advantages, cost benefits, flexibility and might even lead to a truly paperless future. But there are risks as well. Here's how to benefit from the Cloud while ensuring protection and confidentiality of data.

Ensure Accessibility 
Cloud computing is still in its infancy. There are instances of clouds crashing, leaving their clients without access to their files, or worse still, completely unprotected for hours because of errors. Therefore, it is advisable not to trust cloud services completely. Keep on saving your most vital and confidential documents, records, projects and works-in-progress in your personal laptop or desktop.

Secure Your Data
Any computer can malfunction without warning. Build yourself a three-part rescue kit. The first part consists of your installation DVD/CD set for your O/S and drivers. The second part is an ISO image of the entire contents of your computer burned to DVD and updated regularly. The third p…

What is Grid Hosting?

Grid hosting is a service that provides grid computing capabilities to its clients. Grid computing is the application of multiple computers (or servers) to a problem that requires access to a large number of computing cycles. Much like clustered hosting, grid hosting makes it less likely that a spike in resource needs will take your site offline.
Grid hosting is the process of deploying multiple front-end Web servers in a data center that is managed and monitored by a group of IT specialists employed by the Web hosting company. These front-end Web servers are continuously powered up and connected to the Internet 24 hours a day, 7 days per week, all year round. An automated system is implemented into this cluster of front-end Web servers, and this is where the hardware and bandwidth resource usage as well as errors or issues of each front-end Web server are constantly monitored. This in turn allows each front-end Web server to use the hardware and bandwidth resources of other …

How to Choose a Web hosting plan?

Choosing a good hosting plan is somehow very similar to the way how you choose a laptop. You do not need to learn every component inside a laptop to pick a good one; likewise, you do not need to have deep knowledge to pick a good hosting plan. However, you need to know what makes a hosting plan stands out from the others.

Reliability, flexibility, quality and price are the 4 most important elements you need to look after when you evaluate a hosting plan.Price
This is the aspect most of us will look at first when choosing a hosting provider; however, it shouldn’t be the deciding factor. When you see price differences it’s helpful to remember the old maxim that we get what we pay for. Jumping on the cheapest offer you see isn’t necessarily the best idea, especially if you rely on your site to make money. Things like non-outsourced support and quality hardware cost money, and a hosting company that charges $1.99 per month likely won’t offer these features.

If you’re l…

What is Managed Hosting?

The question ‘What is managed hosting?’ can be difficult to answer. The term is slightly ambiguous which has led to each service provider delivering a slightly different version of the same service; all under the heading of ‘managed hosting’.

Managed hosting is an IT provisioning model in which a service provider leases dedicated servers and associated hardware to a single client. The equipment is at the hosting provider's facility and managed there by the service provider.

Managed hosting differs from other dedicated hosting in that the service provider administers the hardware, operating systems and system software. The client usually has administrative access but as a rule rarely uses it, instead interacting with the leased system through a Web-based interface. Typically, the hosting provider is responsible for setting up and configuring hardware, installing and configuring software, technical support, patch management, system maintenance, monitoring and updates.


What is Clustered Hosting?

Clustered hosting is the newest way of hosting your website. A cluster is a group of computers or servers, whose combined computational power provides a service.

Clustered hosting is a type of web hosting that spreads the load of hosting across multiple physical machines, or node, increasing availability and decreasing the chances of one service (e.g., FTP or email) affecting another (e.g., MySQL). Many large websites run on clustered hosting solutions, for example, large discussion forums will tend to run using multiple front-end webservers with multiple back-end database servers.

Typically, most hosting infrastructures are based on the paradigm of using a single physical machine to host multiple hosted services, including web, database, email, FTP and others. A single physical machine is not only a single point of failure, but also has finite capacity for traffic, that in practice can be troublesome for a busy website or for a website that is experiencing transient bursts…
