With the introduction of Everything-As-A-Service (XaaS), organizations can access any service (products, tools, technologies, etc) from the cloud service provider and pay only for what they need. Cloud-based computing services can provide users with much flexibility using multi-tenant approaches. Resource pooling and rapid elasticity allow organizations to add or subtract services as required.
Given the dynamics of modern businesses, the advancement in Artificial Intelligence Complete, Big Data, AI Analytics & Machine Learning Algorithms, Augmented Reality (AR), the Internet of Things (IoT), and automation requires flexible cloud delivery models and specified services support. This factor has contributed to the growth of XaaS and organizations’ acceptance of the model.
Service providers are continuously addressing the security and governance issues of XaaS, removing the hesitation of the organizations towards the XaaS model. Furthermore, cloud computing is a technology that delivers services such as computing, storage, and networking over the Internet. XaaS utilizes technological advancements like AI, ML, Big Data, Automation, and IoT.
In the XaaS delivery model, users can choose services and tools and pay for only these services using a pay-as-you-go cloud computing pricing model. As the cloud services evolved, terms like Database as a Service, Network as a Service, etc., were added to cloud computing. XaaS has seen rapid growth since organizations have shifted their IT infrastructure to the cloud marketplace.
Understanding What Everything-As-A-Service (XaaS) Entails
Everything-As-A-Service (XaaS) is a collective term for Anything-As-A-Service (XaaS) and an umbrella term encompassing products, tools, and technologies provided by cloud vendors as services to users over the Internet on a subscription basis. Eventually, any business-related IT function, such as storage, database, or security, can be transformed into a service for enterprises to consume.
The pricing of most cloud services depends on flexible consumption rather than upfront pricing or licensing. XaaS withholds primary service models IaaS, PaaS, and SaaS and also deals with other functions that are converted as services, such as Disaster Recovery as a Service, Function as a Service, Authentication as a Service, etc. All these are essential elements in business operations.
Technically, the core idea of Everything-As-A-Service (XaaS) is that businesses can cut costs and access specific resources. They can outsource business workflow automation services from providers on a subscription basis. Before XaaS and cloud services, organizations had to buy licensed products, install them, and provide website cybersecurity or infrastructure for business purposes.
Everything-As-A-Service (XaaS) helps integrate cloud computing technology in business environments and provides services at low cost and scales according to the organization’s needs. Moreover, the ability of XaaS to provide small cloud functions such as storage, network, or disaster recovery as an individual service to the users has made it a preferred choice for developers.
How Everything-As-A-Service (XaaS) Helps Foster Cloud Computing
Before the rise of the ‘as-a-service’ model, we had only one choice: acquiring multiple stand-alone solutions bought from different vendors. This option often proved to be extremely expensive and inefficient. Although various systems work great separately, they don’t necessarily work well in combination. Thus, there is a need for a unified service model to help simplify mundane tasks.
Many factors influence the popularity of the ‘as-a-service’ model, and we cannot analyze them all in one article, but we will focus on some of the essential ones. We should pay attention to the recent development of technology and how we use different services. Millennials have grown up in the era of rapid Internet development and have become accustomed to using various solutions.
The XaaS model includes services from companies such as Uber, Airbnb, and Netflix. Uber will no longer own taxis, Airbnb will not own flats, and Netflix will not own a single cinema. Digital disruption has been with millennials for a long time, and they are starting to take over decision-making positions in companies. At the same time, they stopped seeing the value of technology.
Buying every piece of hardware/software means that companies have to invest a relatively high amount of money upfront into equipment, which they could utilize much better in areas like R&D, marketing, or others, especially if they are startups. With the โas-a-serviceโ model, there is no significant investment upfrontโit’s much easier to upsize/downsize the IT environment per needs.
Some Examples Where Everything-As-A-Service (XaaS) Use Applies
According to a report by Belindavas & Webtechex, the Everything-As-A-Service (XaaS) Market is expected to grow from USD 545.35 billion in 2022 to USD 2378.07 billion in 2029. The concepts of SaaS, PaaS, or IaaS are already familiar. However, many more acronyms refer to this solution. Examples include STaaS, CCaaS, MaaS, DRaaS, DBaaS, DaaS, NaaS, UCaaS, BPaaS, and BaaS.
It is worth considering Everything-As-A-Service (XaaS) to understand better how the โas-a-serviceโ model meets the needs of modern businesses and why it continues to gain popularity. In layman’s language, as we mentioned, XaaS is an umbrella term referring to the growing number of services and tools delivered through the cloud and the ability to combine them into a single offering.
Everything-As-A-Service (XaaS) encompasses multiple products, tools, and technologies. Remember, Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) are the core XaaS models. Other models include Database as a Service, Authentication as a Service, Disaster Recovery as a Service, Function as a Service, Network as a Service, etc.
Given the ever-evolving cloud computing technology landscape, all modern organizations and cloud-based businesses require a dynamic cloud computing service model. Under the XaaS model, any cloud function can be provided as a service to the user. Some of these services include security, authentication, networking, etc. Let’s discuss some of these cloud-based computing services.
1. IT as a Service (ITaaS)
On the one hand,ย ITaaS is a cloud-based technology service that allows businesses to access high-quality software and hardware without purchasing, maintaining, or upgrading it. On the other hand, Technology as a Service (also Tech-as-a-Service or TaaS) is a subscription model for your office devices. IT services allow businesses to access the technical tools and information for their operational processes and daily tasks. Often, teams with expertise in IT or computer science manage these services for organizations in many industries. ITaaS marketplace vendors provide laptops, desktops, smartphones, monitors, printers, scanners, tablets, and more, paid monthly, quarterly, or annually.
2. Unified Communications as a Service (UcaaS)
UCaaS is a cloud-delivered unified communications model that supports vital communications functions: enterprise telephony, meetings (audio/video/web conferencing), and unified messaging. โUnified communicationsโ refers to various communication and productivity tools integrated into one platform. Typical tools in UC platforms include VoIP phones, instant messaging, email, online meetings, conferencing, and calendars and scheduling.
3. Infrastructure as a Service (IaaS)
On the one hand, IaaS is a prevalent cloud computing model that delivers computing resources such as virtualization, storage, networks, and servers over the Internet. It eliminates organizations’ need for on-premise infrastructure, cutting costs and maintenance overhead. On the other hand, we can also incorporate Workplace as a Service (WaaS) in this category. With WaaS, purchasing, delivery, customer service, security, maintenance, and upgrades become more accessible for resellers. Hardware can arrive at the end customer fully configured and ready to use. Software, on the other hand, will be conveniently delivered via the cloud.
4. Platform as a Service (PaaS)
One thing is sure: Demand for cloud solutions and services continues to grow, driven by distributed workforces and remote working. Every modern MSP should respond to these market demands by providing their customers with what they need most while increasing their profits. PaaS abstracts another layer in the computing paradigm by including an operating system and runtime environment in the delivered service, apart from IaaS offerings. It provides a platform for developers to build, run, deploy, and manage applications without worrying about the underlying infrastructure or platform associated with the process.
5. Software as a Service (SaaS)
SaaS is a cloud computing model that allows organizations to deliver applications to users. The user can only use the functionalities provided by the developer and has no visibility of underlying infrastructure, code, or build platform. In particular, Google Workspace, Slack, and Office 365 are prevalent examples of Software as a Service. For MSPs, this means growth opportunities, opening up additional sources of recurring revenue, increasing company valuation, and building closer and ongoing relationships with customers and suppliers.
6. Authentication as a Service (AaaS)
AaaS allows organizations to apply multi-factor authentication, single sign-on, and password management to secure access to the application from any device, anywhere. AaaS provides a high level of security and can protect an application from different attacks on authentication procedures, such as man-in-the-middle, Denial of Service (DoS), and brute force. Thanks to authentication and standardization, XaaS also means higher profit through high-margin services and lower service delivery costs.
7. Containers as a Service (CaaS)
CaaS is a cloud service model that allows users to upload, run, organize, manage, scale, and stop containers by using container-based virtualization. A container is a package or software with all dependencies like code, runtime, libraries, and configurations to run on any host system. Without CaaS, software development teams have to deploy and manage the underlying infrastructure on which the container runs.
8. Database as a Service (DBaaS)
DBaaS is a cloud computing service that provides access to a cloud database system without requiring the setup of physical hardware, software installation, or database configuration. The cloud provider is responsible for the database’s upgrades, security, and backup. In other words, some of these XaaS models are more cost-efficient than building an on-premise storage facility. For example, most businesses, organizations, and individuals use STaaS to store multimedia, data backup and recovery, data repositories, and disaster recovery.
9. Desktop as a Service (DaaS)
DaaS is a cloud computing service that delivers virtual desktops to end users over the Internet. The service provider hosts the infrastructure, network, and storage in the cloud and provides the user with a virtual desktop to access data and applications. Generally, the service provider is responsible for maintenance, updates, cloud storage, security, and backup for these desktops.
10. Disaster Recovery as a Service (DRaaS)
The DRaaS model allows organizations to back up their data and IT infrastructure, such as servers, on a third-party cloud vendor. This helps regain access and functionality to IT infrastructure after a disaster, such as a power outage, hardware failure, file corruption, severe cyber attack, earthquake, hurricane, etc. In Disaster Recovery as a Service, terms are predefined by the organization and cloud vendor in a Service Level Agreement (SLA).
11. Function as a Service (FaaS)
FaaS is a cloud computing service model that allows developers to build, run, and manage application packages as a function without worrying about the underlying infrastructure. FaaS follows an event-driven paradigm meaning a function is invoked by any action called an event. The resources are allocated only when the event invokes the function, therefore the organization only pays for the time the function is executing.
12. Network as a Service (NaaS)
NaaS is a cloud service model that allows organizations to operate their network by utilizing network resources provided by service providers. NaaS vendors run networking functions using software, enabling organizations to set up their network without any on-premise hardware.
13. Backup as a Service (BaaS)
Online Backup Service, also known as Cloud Backup or Backup as a Service (BaaS), is a method of offsite data storage in which a service vendor regularly backs up files, folders, or the entire contents of a hard drive to a remote secure cloud-based data repository over a network connection. Through APIs, BaaS provides banking products (such as current accounts and credit cards) to non-bank third parties. One of its primary advantages is rapid app development. By eliminating the need to construct backend functionalities from the ground up, BaaS significantly reduces time-to-market, making it especially valuable for mobile and web app developers.
14. Communication as a Service (CaaS)
CaaS is a cloud-service solution that provides communication services like voice over IP (VoIP) for voice communication, instant messagingย (IM) for text communication, and video conferencing for video communication. CaaS vendor is responsible for all hardware and software management and allows businesses to utilize communication devices pay-as-you-go and as-need. It eliminates the additional cost to the organization in buying, setting up, and maintaining hardware devices.
15. Security as a Service (SECaaS)
SECaaS refers to securing user privacy and corporate data in subscription-based cloud applications. SaaS applications carry a large amount of sensitive data. They can be accessed from almost any device by a mass of users, thus posing a risk to privacy and sensitive information. With SECaaS, you save money and get access to security experts and the latest security tools and updates. You can also take advantage of faster provisioning, simpler in-house management, and the ability to free up other IT professionals.
The Topmost XaaS Advantages
Apart from providing such a wide variety of services to the users. Everything-As-A-Service (XaaS) inherently provides some advantages to organizations. There are still a few other known benefits. For example, consider cost and time effectiveness. Cloud service models cut costs by reducing the organization’s IT infrastructure and using fewer servers, network switches, and storage units.
The organization does not have to buy an unnecessary license and pay upfront costs since it can utilize that service from cloud vendors for the required time and pay as it goes. Moreover, the development time is reduced by easy accessibility to all the cloud services. Likewise, organization owners and managers can focus on business processes by minimizing physical overhead.
Cloud services mean less physical infrastructure on-site and less physical overhead, such as space, power, cooling, etc. This allows businesses to focus more on essential projects and processes, providing better services to users and an improved customer experience. Using third-party services rather than deploying on-premise technology shifts capital to operational expenditures.
In terms of scalability, like other service models, services can easily be scaled up or down based on the need. Equally important, an effective Everything-As-A-Service (XaaS) model allows seamless technical support. Third-party service providers or cloud vendors maintain, upgrade, and troubleshoot the service. As a result, the service user can reduce their on-premise support personnel.
Some Notable XaaS Disadvantages
Accompanied by all the pros, XaaS also has disadvantages that organizations using the XaaS model must deal with. In this case, we can consider a drawback, such as internet reliability downtime. Possible losses in Internet connection threaten the consistent delivery of services. XaaS can cause issues with performance resilience, provisioning, and managing infrastructural resources.
Be that as it may, the potential Everything-As-A-Service (XaaS) providers can guarantee services through a Service Level Agreement (SLA) and ensure more output results. Another notable downside is less internal visibility. Users have limited visibility and control of the service provider environment. There’s also vendor lock-in. Customers rely entirely on cloud vendors for services.
If a cloud vendor discontinues, changes a service, or goes out of business, it might profoundly impact customers. Such conditions should be discussed in SLAs. Next on the list isย potent security risks. In this case, malicious attacks by hackers and cybercriminals are increasing and advancing daily. Any possible security breach on the cloud service provider’s end can put users’ data at risk.
Overall, network traffic congestion (internet reliability), vendor or service provider issues, and security are the primary factors affecting the delivery of services in XaaS. However, with the above drawbacks aside, the core idea of XaaS is to cut business costs by providing only the required services and billing for them. On that note, implementing a strategic working plan is essential.
Summary Notes:
We know three prominent service models in cloud computing: Infrastructure as a Service, Platform as a Service, and Software as a Service. These services encompass the complete cloud computing model and are not flexible. But what if we only want Security, network, authentication, or Storage as a Service? This is where Everything-As-A-Service (XaaS) comes into play.
Everything-As-A-Service (XaaS) or Anything-As-A-Service (XaaS) refers to products, tools, and technologies provided by cloud providers to end users on a subscription basis. XaaS allows the conversion of cloud functions to services and provides these services to users on a pay-as-you-go, as-need basis. A strategic Everything-As-A-Service (XaaS) plan is cost and time-effective.
This is a significant business benefit โ it allows organizations to focus on developing business processes. In addition, an effective model for Everything-As-A-Service (XaaS) is highly scalable. The service provider offers availability and fault tolerance. For instance, consider a model such as Storage as a Service (STaaS). STaaS provides a platform for users to store data on public cloud storage.
