Software as a Service (SaaS)

Software as a Service (SaaS)It is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS). SaaS is closely related to the application service provider (ASP) and on demand computing software delivery models. The hosted application management model of SaaS is similar to ASP, where the provider hosts the customer’s software and delivers it to approved end users over the internet. In the software on demand SaaS model, the provider gives customers network-based access to a single copy of an application that the provider created specifically for SaaS distribution. SaaS applications for fundamental business technologies, such as email, sales management, customer relationship management (CRM), financial management, human resource management (HRM), billing and collaboration. Leading SaaS providers include Salesforce, Oracle, SAP, Intuit and Microsoft. SaaS is a natural evolution of software. The old model of getting physical DVDs and installing on local servers was the only realistic solution for many years. In fact, the client-server model is still required for many scenarios. That said, in recent years a number of developments have allowed SaaS to become mainstream. One factor is bandwidth; the internet is simply faster than it was a decade ago. Other major factors include the evolution of both virtualization and tools in big data. All these advances have made it much easier for providers to scale and manage their own infrastructure and thus provide SaaS solutions.


Advantages Of Saas

SaaS removes the need for organizations to install and run applications on their own computers or in their own data centers. This eliminates the expense of hardware acquisition, provisioning and maintenance, as well as software licensing, installation and support.



Work anywhere & Easy to use and perform proof of concepts

Since the software is hosted in the cloud and accessible over the internet, users can access it via mobile devices wherever they are connected. This includes checking customer order histories prior to a sales call, as well as having access to real time data and real time order taking with the customer. For road warriors, the ability to access the software and data when they need it can change the nature of a sale. with the rise of the internet, SaaS saw deployment in enterprise for employees to access company resources, including software located on the company’s central server. In the consumer space, SaaS was also deployed with popular software including webmail and photo sharing services.

Balancing pros and cons

companies, the pluses have outweighed the minuses, and there has been a trend towards running more software via SaaS with the cloud computing model, and away from hosting it locally. The SaaS market continues to expand, with expected growth to surpass $112.8 billion by 2019. While the internet has made this possible, SaaS is hardly a new phenomenon, and its origins can be traced back to the 1960s, with IBM and other corporations using distributed software packages to connect users with mainframes to provide utility computing.

Slacking on

While office suites have been around for decades at this point, a newer type of SaaS focuses on office communication. Slack bills itself as a collaboration hub and provides a single place for messaging, tools and files.Rather than have communication between team members distributed between multiple platforms, such as shared storage, emails, texts and instant messages, Slack provides a unified platform for providing communication and file exchange between team members working on projects. attractive is that new channels can be created, each focused on its own project, topic,or whatever is needed, to neatly organize the communication, all in a searchable database, secured with two-factor authentication. Slack plans kick-off at the useful free tier that limits your account to the most recent 10,000 messages, with the next tier Standard plan costing $8 and this is unrestricted, plus it’s discounted when paid for annually.
