In other words, it is a type of cloud computing where end users only need Internet access to use the application.<\/p>\n<p>With a SaaS product, the company that buys the use of the SaaS software doesn&#8217;t have to carry out complex software installations or have its own hardware infrastructure. By simply giving its employees access to the software, they are already in a position to use it.<\/p>\n<p>When buying SaaS solutions, you usually sign up for some kind of subscription to use the tool, either monthly or annual.<\/p>\n<h2>1. Advantages of SaaS solutions<\/h2>\n<p>Companies that make use of cloud-based SaaS solutions obtain multiple advantages compared to the purchase of installable application packages. Among those benefits, we can list:<\/p>\n<ul>\n<li><strong>Infrastructure and configuration cost savings.<\/strong> The SaaS model allows users to always work with the latest version of the software, which is hosted on the SaaS solution company&#8217;s infrastructure.<\/li>\n<li><strong>Access from any location.<\/strong> Access to SaaS services can be done from any other Internet-connected device, without the need to install the SaaS service locally.<\/li>\n<li><strong>Very fast deployment.<\/strong> Its configuration is fast because SaaS solutions can be used by users with little or no technical experience.<\/li>\n<li><strong>Ease of expansion.<\/strong> It is usually accessed by licensing or pay-per-use, so it easily adapts to the usage needs of each client. Allowing more users to join without any problems.<\/li>\n<li><strong>It is always updated and secure.<\/strong> SaaS services generally have automatic, frequent and free updates of their tools. This allows the most current and secure version of the tool to be used.<\/li>\n<\/ul>\n<h2>2. Characteristics of SaaS services<\/h2>\n<p>There are several types of SaaS solutions, each with its own peculiarities, but in general, the most common characteristics of SaaS services are as follows:<\/p>\n<ul>\n<li><strong>Cloud architecture.<\/strong> They are designed for multiple users at the same time, so the infrastructure behind SaaS solutions is based on a shared remote infrastructure (maintained by the company providing the SaaS solution).<\/li>\n<li><strong>Convenient access for any connected device.<\/strong> Thanks to this, users can access up-to-date data and information at all times, as it is synchronized in the cloud infrastructure on a recurring basis.<\/li>\n<li><strong>They have an improved UX and UI.<\/strong> Their creators take special care to ensure that the interfaces of their solutions have a simple look and feel based on the browsing experience you would have on the web.<\/li>\n<li><strong>Social and collaborative features.<\/strong> Within SaaS solutions it is very common to have features for several people or departments to establish areas where they can collaborate effectively.<\/li>\n<li><strong>Pay-per-use or fee.<\/strong> Although there are pay-per-use services, the most common model is for the service to be paid for as a monthly or annual subscription. They also usually offer reduced trial or freemium versions where the software&#8217;s features are limited.<\/li>\n<\/ul>\n<h2>3. Examples of SaaS<\/h2>\n<p>You are surely using SaaS solutions in your day-to-day life. Here are some examples of SaaS applications:<\/p>\n<ul>\n<li>Adobe Creative Cloud, a suite for accessing graphic design, video editing tools, etc.<\/li>\n<li>Amazon Web Services (AWS), cloud platform with more than 200 services.<\/li>\n<li>Dropbox, a cloud document storage service.<\/li>\n<li>GitHub, a service for sharing code and your own projects with version control.<\/li>\n<li>Microsoft Office 365, suite of applications for document creation and management.<\/li>\n<li><a href=\"https:\/\/mailrelay.com\/en\/\" target=\"_blank\" rel=\"noopener\">Mailrelay, an email marketing tool<\/a> for sending bulk emails.<\/li>\n<li>Slack, the messaging solution.<\/li>\n<li>WordPress, a <a href=\"https:\/\/mailrelay.com\/en\/glossary\/content-management-system-cms\/\" target=\"_blank\" rel=\"noopener\">CMS<\/a> for website design.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Related entries<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/sender-score-reputation\/\">Sender score reputation<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/reply\/\">Reply<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/corporate-social-responsibility-csr\/\">CSR (Corporate Social Responsibility)<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/responsive-design\/\">Responsive design<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/retail\/\">Retail<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/return-path\/\">Return path<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/rfc-821\/\">RFC 821<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/mailrelay.com\/en\/glossary\/rfm\/\">RFM<\/a><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">You may also be interested in: <a href=\"https:\/\/mailrelay.com\/en\/glossary\/no-code-automation\/\">No-code automation<\/a> and <a href=\"https:\/\/mailrelay.com\/en\/glossary\/arr-annual-recurring-revenue\/\">ARR (Annual Recurring Revenue)<\/a>.<\/p>\n","protected":false},"template":"","class_list":["post-71822","glossary","type-glossary","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
