The Cloud can mean different things to different individuals. But 2 aspects that can be applied globally about cloud is that : Private Cloud is a catalyst not just just for the IT efficiencies, but in a broader perspective, the shared cloud also holds the capability to force changes in other areas of IT as well. Cloud has brought along a major break through for businesses seeking cheaper yet highly efficient IT services.

The IT department of any businesses should have a better understanding about defining and supporting crucial business priorities along-with managing the vendor relationships and internal initiatives.

There are certain questions that must be asked when deploying cloud optimization:

Cloud Hosting

What is the reason for switching to cloud computing ?

The U.S. National Institute for Standards and Technology (NIST) defines cloud computing as: “a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

There are 3 defined categories of cloud services which can be applied internally or externally:

  • Software-as-a-Service (SaaS): The cloud hosting provider deliver applications to customers over a cloud infrastructure which can be accessible via. a web browser.
  • Platform-as-a-Service (PaaS): In this type, cloud-provider offers both a cloud infrastructure and applications related tools and resources such as programming languages to an internal or external customer/user.
  • Infrastructure-as-a-Service (IaaS): The providers provider cloud infrastructure support to support user requirements for running applications and operating systems.

Understanding the Types of Clouds

A cloud can either be a public cloud or private cloud. A public cloud is a set-up where the services are offered on customer demands. Whereas in a private cloud type of service only a single customer owns the entire cloud similar to a dedicated hosting server. When both these Cloud types are used in combination, it is known as the hybrid cloud. In a hybrid cloud a private cloud is hosted in a public environment.

Generally, the cloud computing has a front-end where the clients can log-in and perform tasks in the back-end which is hosted by the cloud hosting provider. The front-end covers the customer computers and the applications essential for accessing the cloud. Internet is the medium used to communicate between the two.

Cloud Server Hosting

Below is an elaboration of the different types of Cloud hosting services.

Types of Cloud services:

  • Infrastructure as a service (IaaS): As the name itself suggests, in this type of service offering, the Infrastructure is provided as a service. Here the customers application interface access the virtual servers and storage hosted by the provider.
  • Platform as a service (PaaS): Platform within the cloud/ shared cloud is a set of applications or software’s that operates on the platform that is hosted in the cloud. The customers can run the applications in the platforms hosted by the cloud hosting provider through the platform or Application Program Interface (API).
  • Software as a service (SaaS): In software as a service model, both hardware as well as software infrastructure is offered for usage to customers.
  • Hybrid cloud: A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization might use a public cloud service, for accessing data but still continue with its maintenance in-house storage for operational customer data. Ideally, the hybrid approach allows a business to take advantage of the scalability and cost-effectiveness that a public cloud computing environment offers without exposing mission-critical applications and data to third-party vulnerabilities.

Cloud computing and enterprise architecture, complimenting each other

Since sometime, its been a debating scenario the advent of cloud computing means for the future of enterprise architecture. Few claim that the increasing use of cloud computing would render enterprise architecture obsolete or irrelevant, whereas few have a more moderate approach and see the two developing in tandem.

Though cloud computing might alter the nature of how software’s are used, but it is unlikely to change the requirement for a coherent strategy which would incorporate the business and enterprise targets of any business, hence in-order to achieve this , the enterprise architecture would always be a necessity.

Experts have stated that a shift towards cloud computing, “doesn’t change the underlying reality that there has to be a strategy for putting together all the people, processes and tools that the cloud supports in order to maintain security and reliability.” Yeah it may so happen that the role of an enterprise architect changes.

No matter if the software, data and communication services is supplied by a third party vendor, the fact still remains that the processes for incorporating these will stay with the business itself. May be, there would be a better way to look at the cloud computing revolution is as a tool that would enable more efficient and dynamic enterprise architectures as we move ahead in time.

We must understand that the evolution of Cloud (both Private Cloud as well as Shared Cloud) and Cloud Hosting is inorder to make technological resources further accessible and potentially more affordable web hosting ultimately.

Many a times it may happen that a bad DNS entry would get cached and it becomes essential to either flush (or clear) the DNS cache to bring things back to normal, or simply hold on until twenty four hours to get dropped from the cache on its own. Instead, there is a way to forcible flush it out from the system.

Here is how you do that :

For Windows users
In the command prompt you must type the command “ipconfig /flushdns” to flush the DNS resolver cache.

C:\ipconfig /flushdns

For Mac OSX

In Mac OSX, you need to type the command “dscachetil -flushcache” for flushing the DNS resolver cache.

bash-2.05a$ dscacheutil -flushcache

For Unix and Linux versions/editions

For Linux, the nscd daemon is responsible for managing the DNS cache. For flushing the DNS cache, you simply need to restart the nscd daemon.
For restarting the nscd daemon, use the command

/etc/rc.d/init.d/nscd restart

Most web hosts offering Virtual Private Server, Cloud Hosting and other Web Hosting UK services would allow you the privileges to flush DNS.

Useful Tips for making a web site Mobile friendly

Posted by admin | Posted in Business Web Hosting | Posted on 08-11-2010

With the emergence of smart phones, there are lot of things happening in the web-designing and development arena. Apart from considering only the user experience, the clean codes or the CSS (Cascaded Style Sheets), making a website mobile compatible is one of the most important aspects of website designing and development.

With an increasing volume of users for the mobile phones and the packages that are now being offered by the providers, the demand for a mobile friendly websites is on its peak now a days.

Let us now take a look at the factors which would help you create mobile compatible websites

Fluid Width Layouts

Fluid width layouts are considered to be one of the most important steps for making your website mobile compatible. It enables you with the stretching or shrinking the site as per the browser size. But as a matter of fact,to have a layout that flows with the width of the screen’s resolution is more convenient, more often than not the website was originally laid out for a desktop in mind. To compress a fluid layout to 320 pixels can prove to be fatal for the layout. Hence, it is good to have a mobile style-sheet and laying out the content specifically for that screen and have more control on the display.

One of the best things is to try and identify the type of platform which is connected to the site and disable or alter the tools and effects to make it look a level better.

Keeping the Page size to minimum

When in process of creating your website mobile friendly, it is important that you keep short webpages on your site. Considering the fact that, no matter how large a mobile screen is, its still small as compared to a laptop or a PC screen (monitor). Hence, design your webpage with an intention that the users would require to scroll as minimum as possible. Also, webpages that offer short but to the point information are admired by users, this would further help in decreasing the load time.

Assuming that your website would be accessed by users who do not have mobiles with QWERTY keyboards, for them it would be easier if the have to type less. So, shorter urls can be helpful to users.

Easier Navigation and Search bar

Easy and user friendly navigation structure of any website plays a crucial role in its success. So when designing a navigational structure, make it a point that even the mobile users should be able to easily surf through your website. As far as possible try and keep your webpage content in the center, this should ease users from straining their eyes while reading your webpage. A clearly visible search bar with easily findable function keys can prove useful. Google can be considered to be an ideal website even when accessing it over the mobiles. An easy navigation structure can prove to be useful to users.

When it comes to browsing website with a Mobile, take utmost care when writing the Website Code

Clean code is an important aspect when considering the diversity in the handheld devices. Some cell phones might understand only WAP. While some cell-phones would understand WAP2, which enables rendering websites with XHTML and CSS. Most mobiles won’t display tables, floats, frames, JavaScript, and dynamic menus. Usually, no mobile-phone doesn’t support cookies.

But, with the regular improvements taking place day-by-day in the industry of mobile telephony, some mobile manufacturers such as BlackBerry, iPhone etc are capable of supporting almost anything similar to any computer.
