The SaaS industry mainly relies on the Cloud Delivery model to deliver its services, which means the provider hosts their databases, networks, and computing operations in their servers.

The other model is the ISV, the software provider contracts space from a cloud provider to host the software in the provider’s data center.

SaaS companies usually integrate different software using API to offer flexible and complex solutions.

Using the multi-tenant approach, SaaS companies run on the cloud only one instance of the software for all users, allowing implementing updates, fixing bugs, and doing maintenance fast and efficiently instead of using multiple instances as IOS or Windows do.

This business model is budget-friendly because it often includes maintenance, compliance, security services, and saving money on IT, security, and hardware requisites, which can be time and money-consuming. They also offer support and customer service.

SaaS companies offer dynamic and out-of-the-box solutions, simple to set up, and complex levels for different sizes and needs companies.

History of the Software as a Service Industry.

The cost-efficiency, ease to use, functionalities, and third-party maintenance and security led the SaaS to experience exponential growth in the 2000′. But what happened before that?

Early steps

In the early 60′, digital computing hardware technology was a very promising baby that took its time to grow. The cost and size, the engineering team, and the maintenance needed to run any mainframe were costly and therefore exclusive.

Personal Computer Era

The hardware considerably reduced its cost and size in the next three decades, so now, an individual could “own” a personal computer. The On-Premise Software made its appearance and, with it, the “intranet.”

On-premise was time-consuming and not scalable, and the IT departments were living a nightmare trying to install, update, secure, and maintain all the hardware and software. In this stage, the software business had a low earning margin due to the cost of the goods sold.

Dotcom empire

When the internet exploded in 1994, all the businesses associated did. In 1995 Jeff Bezos launched Amazon and Pierre Pierre Omidyar AuctionWeb, now eBay, the first P2P auction marketplace.

Cloud Computing; The Rise of SaaS.

With the rise of the internet, cloud computing emerged; this allowed remotely hosted Software to be installed on any computer with internet access. The Software reduced its amount of maintenance for the first time, and reach significantly increased. Software developers began to focus on core functionalities more than anything.

And saas, SaaS appeared.

Salesforce launched its customer relationship management platform (CRM) in 1991, the first SaaS solution on the market. At first, SaaS was only for start-ups and small businesses, and it was thought to be too slow, unstable, and inflexible for more prominent companies. The subscription-based software business model wasn’t too appealing for the companies back then.

SaaS Explosion

Nowadays, the SaaS industry is present in almost every business you can find in the market, using email providers, social networks, CRM platforms, etc. The exponential growth the SaaS industry experienced was rocket-fueled by the rise of the entrepreneurs and small businesses that now have access to sophisticated software to make complex operations. That was a luxury that only big companies could afford in the past.

Why is SaaS important?

The Saas Industry pulled down from the sky and down the earth many services affordable to anyone, from freelancers and entrepreneurs to big companies like IBM, Microsoft, Oracle, or SAP. The level of automation of the SaaS helped the global market grow and create riches that everyone can enjoy today. You can buy a t-shirt from china or a MacBook from the United States using Amazon. The amount of SaaS, IaaS, and PaaS involved is enormous. We don’t realize they prove that the SaaS industry is doing a good job.

With the advance in AI technology, the integration in the market will be hand in hand with the SaaS, which will make available those technologies to all of uOnly the SaaS can manage the amount of software integration we’ll have in the future.

The importance of the future of the business and the technology that the SaaS industry will have will be paramount.
