The World of Software-as-a-Service Options is increasing steadily

Author:Elan Emerging Technologies

Cloud computing is method of computing which relies on shared resources which are all available on demand, just like it is available for people from the electricity grid. This delivery model for IT services is extremely popular and since recession looms large any time during these volatile economic conditions, SaaS is the way to go for many enterprises. The resources are dynamically scalable and virtual which are available online. The physical infrastructure is not available to the client since the resources are rented by a third-party provider. The services are available for consumption as and when needed.

PaaS refers to platform-as-a-service which refers to the storage and hosting which is delivered online as a chargeable service. Hence developers find development and deployment of apps easy since they do not have to worry about the cost and complexity of the procurement and management of hardware, middleware and software. Google App Engine, Microsoft Azure, and the like are examples of PaaS

Cloud infrastructure services are sometimes referred to as IaaS where the entire infrastructure, is provided as a service without having to procure and configure servers or any other equipment. The entire service is referred to as utility computing and the entire consumption of services show the activity. IaaS refers to virtual servers which are entirely leased by providers like Amazon and Rackspace.

Here are some of the types of SaaS solutions:

Business Utility SaaS includes apps like Salesforce automation which are used by many companies for data collection and management. The applications also help in managing collaboration and actionable analysis. CRM and HR portals are examples of these business utilities.

Social Networking SaaS includes social networking apps like the immensely popular Facebook as means of sharing information, photos and the like.

Some Platform-as-a-Service (PaaS) solutions are created different from each other. One needs to study the PaaS solutions before choosing the platform which suits one\'s needs. The most famous platforms are Amazon Web Services and Rackspace. One can upload software stack traditionally and then run applications on the entire infrastructure. Some of the most popular web application platforms include Google Apps which offers multiple and useful functionalities for developers to build services based on mapping, calendar and even the dynamic spreadsheets.

Business Application Platforms including WOLF provides a big layer of abstraction and aligned towards transactional business applications like workflows and online databases. Analysts can develop complex business applications with a custom UI with lesser technical effort and low maintenance.

Now here are some of the general types of IaaS solutions. Cloud IaaS providers deliver various types of services including:

• Storage Computing


• Testing and Development of Apps


• High Performance-based Computing


• Resource Sharing and Virtualization

There are public clouds and there are community clouds. Public clouds are those clouds which deliver resources on a self-service basis online. These services are efficiently delivered by third-party providers who share their resources on a utility computing basis. A community cloud on the other hand by organizations who are interested in similar things and requirements and also willing to share their resources.

Then there are hybrid clouds which are extremely popular. The organizations always choose to leverage their existing investments in their own infrastructure. Furthermore, many companies prefer to have critical data under their own hood for enhanced security.

The new technology stack - SaaS and Cloud Computing

The new technology stack - SaaS and cloud computing

Author:Laksh

There were times when the majority of the commercial technology stack was controlled by Microsoft and Intel, this combination of two companies was so powerful that they were often referred to through a single term; Wintel. However, things have changed.This is probably more true of the technology industry than it is of others.

Cloud computing represents commoditisation of server infrastructure and has been enabled by the increasing power of processors coupled with the maturing of virtual machine technologies. In the past software companies that were offering a serious online service were forced to commission hardware pay for OS licences and other dependencies such as database servers. The costs associated with this were significant and required a long term contract to be signed with the data centre or company hosting the infrastructure. Better, more powerful processors and virtual machines allowed multiple clients to be hosted on a single set of hardware. In turn the hosting companies could adjust their pricing model to reflect their new found agility. Cheap computer power on demand has changed everything, from players to the technology stack being used.

With computer power as a commodity, new pricing structures become viable and attractive. In the past large sums of money were required up front by a provider to cover the costs of commissioning hardware and other one off costs associated with the infrastructure. The cloud allows providers to reduce or in some cases eliminate the upfront fees and provide their technology or service for a monthly cost. The Software as a Service or ‘SaaS\' model holds significant benefits to both the provider and the client. A major headache for software providers in the past has been around funding on-going development of their technology. A SaaS model provides them a steady revenue stream around which they can plan the forward development of the product. Their clients see a steady improvement in the service offered and don\'t have to weigh up the ROI of upgrading to a new version of software when it is released.

One of the design goals behind the workflow management and operational improvement product b-workflow was to utilise cloud technology so that they could offer an attractive software platform at an affordable price. The cloud provides users anywhere anytime access to b-workflow. With database backups and product updates all included in the monthly per user fee, users of workflow software can concentrate on their procedures and checklists and can conduct them from where ever is convenient, the office, at home or on the road.

With a WYSIWYG style editor to design checklists, dashboards and a clean intuitive interface accessed through a web browser or smart phone, b-workflow is a highly flexible solution for mapping an organisations procedures and checklists. Date and time that items are completed at are automatically gathered by the system. Checklists can also obtain the geo-location that a checklist was completed at, giving a greater level of accountability for out of office employees, such as area managers or sales people completing remote checklists.

The combination of powerful mobile devices, cheap compute power and the SaaS pricing model enable software solutions such as b-workflow to be delivered in a convenient, efficient and cost effective manner.

Cloud Computing And SaaS Web Apps Deployment

Cloud Computing And SaaS Web Apps Deployment

Author: Elan Techno

SaaS (Software as a Service) had almost met its doom in 2001 but it crawled back into contention due to the need of companies to combat with high-cost IT infrastructure. SaaS was revolutionary when it came in, but the expectations were too huge to be fulfilled. SaaS has now managed to smother other new technologies and has several versions in the form of Infrastructure as a service and Platform as a service. SaaS has considerably regained its stature since the dot com bubble burst and has grown in recent years.

SaaS web apps started out as point solutions and the first players in the market included UpShot and SalesNet. These solutions provided services related to specific business needs but did not have a huge customer following even though the idea was new and useful. The features were limited and the resources were limited too at their disposal. The competitors who started out offering SaaS solutions offered better features after the dot com bubble while the originators lost their place of importance and eventually vanished into thin air.

Feasibility of cloud computing and SaaS

The feasibility of cloud computing services has always been undetermined since it is difficult to quantify the benefits as well as its utility in any business context. Business requirements have always mentioned the need for low cost but efficient infrastructure but with no solid and structured cloud computing solution in place, it was difficult for businesses to opt for cloud computing. SaaS proved to be an efficient mode of delivery but it is important to know that the IT setup has evolved well over the years and the security measures are better than they were, years before.

Nowadays, there are businesses that are not wary of offshore software testing because of the fantastic setup of offshore service providers. Most are willing to outsource their non-core IT tasks to offshore locations. The cloud has made it possible to save time and money and set up virtual offices to get their tasks done.

Importance of Cloud computing and SaaS web apps

Cloud computing solutions are great for small businesses since they are scalable according to the needs. Additionally, they can even handle the immense workload at cheap monthly prices.

SaaS has grown to several heights and now has become mission-critical too. It has transitioned well from being a unit silo process to a full-fledged enterprise mode of delivery and the SaaS web apps are used for mission-critical purposes related to ERP solutions.

Cloud computing services consumed from external service providers have taken a huge chunk of the total services offered, according to a Gartner report. The cloud market is preferred today by many with the advent of Amazon Web Services and Microsoft Azure capitalizing on the surge of interest in people for cloud computing. Many organizations have expressed their desired to get into cloud computing by allocating a part of their IT budget for the same. Many of them plan to allocate budget for cloud computing in the near future.

Three Main Service Models of Cloud Computing

What Types of Services Are Available Via the Cloud Computing Service Model?

By Clyde Johnson

As you can appreciate Cloud Computing is really in its infancy and is therefore likely to change drastically over time. Cloud computing is basically computing service. In this computing service model, all the servers, networks, applications and other elements that are associated with data centers are made accessible to IT and end users via the Internet, in such a way that allows IT to acquire only the type and amount of computing services that they actually need. The cloud service model varies from traditional outsourcers in a way that customers do not turn over their own IT resources to be managed and controlled. Instead they plug into the "cloud" for infrastructure services, platform (operating system) services, or software services, treating the "cloud" much as they would treat an internal data center or computer performing the same functions, essentially as a service.

 

[caption id="attachment_59" align="aligncenter" width="300"] Three Main Service Models of Cloud Computing[/caption]

The main services provided by cloud computing service model can basically be divided into three main categories namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).

Infrastructure-as-a-Service (IaaS) provides virtual servers with unique IP addresses. Also, it provides blocks of storage on demand. Customers benefit from an API from which they can control and manage their servers. Moreover, because of the economies of scale and specialization involved, this not only brings advantages to the users but also to the business providing the infrastructure. This service is also known as utility computing since the customers can pay for exactly the amount of service they use, like for electricity or water. It provides grids, clusters and virtualized servers, networks, storage and systems software designed to expand or substitute the functions of an entire data center. IaaS allows an internet business to develop and grow on demand.The best example of IaaS is Amazon's Elastic Compute Cloud [EC2] and Simple Storage Service, however, IBM and other traditional IT vendors are also offering services, as is telecom-and-more provider Verizon Business.

Platform-as-a-Service (PaaS) is a set of software and development tools that are hosted on the provider's servers. Developers can create applications using the provider's API's. It should be taken in account by the developers that there are not any interoperability standards maintained as yet, so some providers may not let them to take their application and put it on another platform. PaaS basically provides virtualized servers on which users can run existing applications or develop new ones without being worried about maintaining the operating systems, server hardware, load balancing or computing capacity. PaaS also allows a lot of scalability by design. Google Apps is one of the most famous Platform-as-a-Service providers. Other good examples include Microsoft's Azure and Salesforce's Force.com.

The third type which is Software-as-a-Service (SaaS) makes the broadest market. It is the most widely known and broadly used form of cloud computing.In this service, the providers allow the customers only to use their applications. The software through user interface interacts with the user. SaaS offers all the functions of a sophisticated traditional application. However, these applications are provided through a Web browser, and not by a locally-installed application. It reduces worries to a great extent about application servers, storage, application development and other common concerns of IT. Salesforce.com, Google's Gmail and Apps, instant messaging from AOL, Yahoo and Google, Twitter and VoIP from Vonage and Skype are some common examples of SaaS providers.

In conclusion cloud computing is essentially a type of computing service model that can be used at anytime, that increases on demand and decreases when you don't have a demand, making it something that appears quite attractive especially in the current economic climate.
