X as a Service model is experiencing constant growth. It offers plenty of opportunities by disrupting the traditional business models. Netflix, Google Suite, Facebook, all of those applications are based on cloud computing. It allows them to enhance their customer’s experience.
Cloud computing makes it easier & simpler for all organisations to pursue the digital transformation process. It allows organisations to focus on developing their competitive advantage. Google launched Chromebook to promote the cloud services applications to the direct consumer.
What is the X as a Service model?
All the X as a Service models are based on cloud computing. According to Techopedia, “Cloud computing is the use of various services, such as software development platforms, servers, storage and software, over the internet rather than on the PCs. The cloud computing vendors offer: full management of the application’s back-end (especially hardware), pay per use, and scalable services.” Storage, computation and analytics capabilities of the cloud are important in the era of Big Data.
Cloud is divided into 3 sub-categories:
Private: a data infrastructure that is used solely by one organisation, so it can control & manage its data confidentially.
Public: vendors own & manage it. They offer a rapid access for the organisations via the internet, such as Amazon Web Services.
Hybrid: It’s the use of private cloud for confidential data, and public cloud as a substitute & emergency.
Cloud services are deployed on one of those sub-categories according to the end-user requirements.
The XaaS solutions’ model are divided into 3 principal services:
- Infrastructure as a Service: It’s the 1st layer of the cloud. It provides organisations computer infrastructure, such as servers, storage, networking, and data center space. The leading IaaS vendors include AWS EC2, Microsoft Azure, & Google Cloud.
- Platform as a Service: It provides a cloud-based environment with all tools to support the processes of building & delivering cloud applications, such as SaaS. Other models are built on it in order to facilitate developers’ tasks. For example : Communication Platform as a Service, Mobile Platform as a Service and Message as a Platform all help to make developers life easier by disrupting the market. AWS Elastic, Azure, Predix GE are the main providers of Paas applications.
- Software as a Service: it’s a web-based service that provides access to a software. It’s not installed on the hardware of the user, it’s used via the browser. It disrupts the business functions and industries. It’s the source of the organisations’ digital transformation. We may find applications on accounting as Sage Accounting; Marketing as Salesforce; ERP as SAP S/4 HANA; E-commerce as Lengow; CMS as Magneto & WordPress; IT developers: GitHub. The big tech companies, like Oracle, offers cloud business solutions suite. There are also high growth of niche B2B start-ups offering specific business function solutions, such as managing the SEO, or Payroll. The development of new solutions as a Service is on constant growth. They are the heart of the digital transformation economy. Those models revolutionize the way we live.
Due to the amount of data required for the evolution of those technologies, the 3rd platform technologies depend on the Cloud such as Blockchain, Machine Learning, IoT, etc.
Convenience (speed of latency), Scalability, Low cost, Security, Ubiquitous (anytime, anywhere), & Availability are the common reasons that incite organisations to initiate their digital transformation via cloud services.
