SaaS is a cloud technology that allows you to use software online without installing it on a computer. The abbreviation SaaS stands for Software as a Service.
SaaS resembles rental housing. You rent an apartment with furniture, appliances and even dishes for any period. You live there, and its owner is engaged in maintenance and repair.
Most SaaS platforms, along with access to software, provide data storage services (projects, information, letters). But there are services where projects are not saved. In them, the work is organized according to the principle: worked — downloaded — left.

Software by subscription
SaaS services provide subscription services. Usually, such companies offer different tariffs, the cost of which increases along with the number of available tools and the size of the cloud storage.
On many platforms, you can collect your tariff as in the constructor and pay only for the services that you use. Other services offer several formed tariffs for different tasks and requests.
It is convenient that you can not pay for all the features of the service at once. Needs have changed — change the tariff.
In addition, almost all services have a trial period or a demo tariff with reduced features for getting acquainted with the product.
SaaS examples
SaaS products have been known for a long time. The first representatives of this model are considered to be mail services.
Today, according to the SaaS model, they work:
- Text, image and video editors (GoogleDocs, Figma, Canva, Adobe);
- Social networks (Facebook, Linkledin, Twitter).
- Video and audio hosting services (YouTube, SoundCloud).
- CRM systems (Bitrix24, Salesforce).
- E-commerce systems (BigCommerce, Shopify).
- Site builders (WiX, Setup, uCoz).
- Enterprise Management Systems (1C: ERP, SAP Business One).
The Unisender mailing service is also a SaaS service that provides tools for email marketers by subscription.
There are whole complexes of SaaS services. For example, Google and Yandex is the postal service, document editors, video applications, tools, online marketing, drives to store information.
Advantages and disadvantages of SaaS
Cloud technologies are convenient to use, and this is not the only advantage of such services.
Advantages of SaaS:
- Low price. A software subscription costs much less than the purchase of a license.
- The ability to work together. In many services, several performers can work on one project at the same time.
- Low probability of data loss due to technical problems. It is not terrible if the computer freezes during operation, the lights are turned off or you forget to save. In SaaS, data is saved immediately as it is introduced.
- Account availability from different devices. You can start doing something in the office, and then go to a meeting by taxi and continue working from the phone.
- Regular updates. Cloud services are constantly updated by a team of specialists without any effort on the part of users.
- Reducing the load on the user's gadgets and equipment. You do not need to use memory to install many different programs — a browser is enough. There is also no need to buy expensive powerful equipment — the entire load falls on the servers of the service provider.
But even such a popular model has some disadvantages:
- High price in the long run. Using a paid service for a long time may be more expensive than paying for licensed software once.
- The risk of information loss. All data is stored with the provider. If the servers stop working or are hacked, you may lose valuable information.
- Low operating speed at high loads. The capabilities of the service provider's equipment are not unlimited, if a large number of users are connected to the cloud at the same time, the speed of work decreases.
A key factor in the development of SaaS
Remember how we installed software before the advent of SaaS — we searched for hacked programs from friends or downloaded keygen on the Internet. Those who could afford it paid for the license.
Today, we are already taking full advantage of the capabilities of cloud services, without even thinking about how much they have made our lives easier. Now we can close the laptop, come to work, enter the username and password to log in to the account on the computer and continue working from the same place.
Since SaaS is based on the principle of providing services via the Internet, the development of cloud technologies is directly related to the history of the world Wide Web.
The abbreviation SaaS appeared in 2001. Since that time, the popularity of cloud technologies has been growing along with the speed of the Internet.
The emergence of high-speed networks, wi-fi and the constant improvement of mobile communication standards invariably entails new upgrades in the field of SaaS. The throughput of services, the speed of information processing, the volume of storage are increasing, the tools are becoming more complex and expanding.
What is a cloud service and why is it so called
SaaS is a cloud service, the highest form of cloud technologies, which have their own hierarchy:
- IaaS is an infrastructure as a service, for example, a virtual data center or a virtual server.
- PaaS is a platform as a service, or a cloud development environment.
- SaaS - software as a service, or a ready-made application for work, which is located in the cloud.
All together, it is called XaaS — "everything as a service", where X is considered as an unknown variable, instead of which you can substitute the desired letter.
Cloud computing is called computing that is performed simultaneously on several servers connected by a network. In this scenario, data processing and storage takes place in a place that is difficult to imagine as something concrete — it is ephemeral and elusive, like a cloud. The user cannot touch it or see what is hidden inside.
A less popular name for cloud technologies is cluster technologies. Cluster translates as a swarm (of bees), a cluster, a brush (of grapes). This word is used in Internet technologies to refer to a group of computers connected together through a network.
Data security in cloud services
We actively use SaaS services for work and personal tasks. Photos and correspondence are stored in mailers and messengers, projects are stored in application repositories, and information about costs and cost is stored in the enterprise management system. All this is our data, which is unique and highly valued.
An important principle of cloud work is that the user's information belongs only to him. Self-respecting SaaS services provide customers with the ability to export data and leave the platform at any time. But not everyone does this. Therefore, before settling on a cloud service, it is necessary to study this issue.
SaaS services are constantly working on the security of customer data, introducing new means of protection. But the professional community has not yet come to a consensus on the reliability of SaaS. Despite all the efforts of providers, the risks remain. Moreover, even large companies are not immune from them.
The threats to which customer information is exposed in the cloud can be divided into three categories.
Physical data loss
Users from the 2000s have repeatedly found themselves in situations where a broken hard drive or a washed USB flash drive entailed a lot of problems associated with the loss of information.
In cloud storage, such situations are practically excluded. Several servers are used for calculations at once, data is stored in different places, there are backups. Therefore, a technical malfunction of one or more servers does not lead to data loss.
If the server is damaged, the technical team of the service will work in emergency mode until the problem is fixed.
Hacker attacks
Hackers break into cloud servers for various reasons: to collect information about user behavior, to damage large businesses, to steal unique data, assets, money. An attack on the cloud is sometimes organized by competitors who want to undermine the reputation of the service.
In 2014, there was a major scandal related to the leakage of Apple user data. A specialized iCloud storage was hacked, and personal information was available to everyone. After this incident, Apple seriously took up the security issue and installed several additional shields: password verification, two-factor authentication, data encryption.
There are many such examples in the history of SaaS, and each incident entails the emergence of new ways of protection. Today, a user's account is an impregnable fortress, but black programmers continue to look for ways to get inside.
Illegal actions of the owners or employees of the SaaS service
One of the fears of SaaS users is what if my data is sold by the service itself?
The second level of legal protection is an agreement between the service provider and the client. To use the service, we sign a public offer agreement (check the box without reading it). It is here that it is stated in which cases the service provider company has the right to use your data. This is usually a standard document. However, owners can leave loopholes for themselves to study user behavior.
But even such a serious protection does not exclude unpleasant situations. In 2018, the data of 87 million Facebook users were transferred without their knowledge to an analytical firm that used the information to promote Trump's election campaign and the PR campaign for the referendum on Britain's exit from the European Union. It is believed that all this happened with the tacit consent of the Facebook management. The company lost about $ 60 billion in a few days due to a drop in shares, the "Delete Facebook" campaign swept through Twitter, the social network experienced a serious reputational crisis. In 2019, a US federal court ordered Facebook to pay a 5 billion fine and review the terms of protecting the privacy of its users.
Such incidents cause serious damage to cloud service providers, so they are trying their best to protect user data. But, as they say, God protects the safe.
How to secure your data:
- Try not to store information in cloud services, the theft of which will cause serious problems, or encrypt it additionally. You can use both ordinary archives with passwords, and special software for encrypting data.
- Store information on several services at once or duplicate it on physical media.
- Use all the opportunities to improve security: do not be lazy to come up with strong passwords that are different for all sites; use two-factor authentication; put passwords on gadgets and computers.
- Carefully read the contract, before signing it, study all the information and reviews about the provider with whom you plan to cooperate.
- Install a good antivirus and antispyware.
Will SaaS be able to completely replace local software
SaaS services have made our life easier. There are even devices on the market where only browsers are installed, and all the rest of the software is available from the cloud (for example, a Chromebook laptop).
It is not surprising that cloud technologies have been experiencing an unprecedented boom in recent years. In 2019, the profit from the sale of services for this model worldwide increased by 26% compared to 2018.
In 2020, the development of SaaS was affected by the coronavirus pandemic and the transition of many companies to remote work. Key cloud giants have doubled their revenues during the year, and by 2025, the value of the entire cloud technology market is projected to double.
SaaS services have seriously reformatted our lives. The creation of virtual offices made it possible to introduce a remote mode of operation. The State of Remote Work global survey in 2018 showed that before the quarantine, employees of 16% of companies around the world worked completely remotely, 40% of employers offered a choice. For comparison — in 1995, the number of organizations with the option of remote work was only 9%.
After the quarantine began, entire industries moved to the cloud — IT, design, journalism, marketing and other areas for which the constant presence of an employee in the office is not necessary. The trend of 2021 is the rejection of offices, announced by a number of IT companies.
But not everyone can afford to completely switch to SaaS technologies. For example, professional work with sound and video is still carried out on local software — a sufficiently powerful cloud service has not yet been created for this purpose. Adds a fly in the ointment and the fear of data loss when an account is hacked.
Therefore, experts predict that in the foreseeable future, SaaS platforms and physical media will work in tandem, and we will be able to choose when it is more convenient to use local software, and when it is more convenient to use subscription programs.
