Looking for Cloud Strategy Consulting? Define the roadmap for your enterprise-wide cloud strategy implementation now!The following is a brief description of the three types of cloud models and their benefits. 1. SaaSSaaS or Software as a Service is a model that gives quick access to cloud-based web applications. The vendor controls the entire computing stack, which you can access using a web browser. These applications run on the cloud and you can use them by a paid licensed subscription or for free with limited access. SaaS does not require any installations or downloads in your existing computing infrastructure. This eliminates the need for installing applications on each of your computers with the maintenance and support taken over by the vendor. Some known examples of SaaS include Google G Suite, Microsoft Office 365, Dropbox, etc. 2. IaaSIaaS or Infrastructure as a Service is basically a virtual provision of computing resources over the cloud. An IaaS cloud provider can give you the entire range of computing infrastructures such as storage, servers, networking hardware alongside maintenance and support. Businesses can opt for computing resources of their requirement without the need to install hardware on their premises. Amazon Web Services, Microsoft Azure, and Google Compute Engine are some of the leading IaaS cloud service providers. 3. PaaSPlatform as a Service or PaaS is essentially a cloud base where you can develop, test, and organize the different applications for your business. Implementing PaaS simplifies the process of enterprise software development. The virtual runtime environment provided by PaaS gives a favorable space for developing and testing applications. The entire resources offered in the form of servers, storage, and networking are manageable either by the company or a platform provider. Google App Engine and AWS Elastic Beanstalk are two typical examples of PaaS. PaaS is also subscription-based and gives you flexible pricing options depending on your business requirements. Adopting Cloud – Choosing Between SaaS, IaaS, and PaaSGoing through the details of what SaaS, PaaS, and IaaS may have given you a general understanding of these three cloud models. Each of them differs and has a range of advantages and disadvantages that may or may not fit in with your business model. By correlating each of these cloud models side by side, you could derive a conclusion on whether it suits your business requirements. SaaSBenefits:
Why Should One Opt SaaS?With SaaS, communication, transferring of content, and scheduling meetings are made easy. SaaS is the ideal choice for small-scale businesses that do not have the necessary budget and resources to deploy on on-premise hardware. Besides, companies that require frequent collaboration on their projects will find SaaS platforms useful. Studies reveal that Supply Chain Management, Business Intelligence, Enterprise Resource Planning (ERP), and Project and Portfolio Management will see the fastest growth in end-user spending on SaaS applications, through 2022.
