What are the Main Types of XaaS

Popular XaaS examples in cloud computing are:

  • Software as a Service (SaaS): In SaaS, the cloud provider offers bundles of applications to consumers in subscription model. Businesses can integrate software solutions in their tech stack to avoid creating them on their own. It is the most popular category among XaaS types to individuals. Examples include MS Office 365, Salesforce, Google Workspace Suite, Adobe Creative Cloud, etc.

  • Platform as a Service (PaaS): PaaS offers an environment and tools to developers for hosting, development and testing of applications and services in different configurations. It helps reduce the burden on IT teams to invest in and manage development infrastructure. Examples include Heroku, Apache Stratos, AWS Elastic Beanstalk, Azure WebApp, etc.

  • Infrastructure as Service (IaaS): In IaaS, cloud providers take care of deployment, configuration, and remote management of compute resources like virtual machines and data center storage. Businesses can access and control the infrastructure over a long term or temporarily without making a permanent purchase. Examples of IaaS services are Google Compute Engine and MS Azure.

  • Disaster Recovery as a Service (DRaaS): Businesses can back up their IT infrastructure and sensitive data in the environment provided by the cloud vendor for use after natural disasters, cyberattacks, power outages, and equipment failures. This helps ensure business continuity by processing data even if the original infrastructure is destroyed.

  • Functions as a Service (FaaS): This service is meant for developers who want to write modular codes in the cloud environment for adding functionalities that are triggered based on different events. Also called serverless computing, this model is responsible for implementing microservices architecture that is highly popular these days. XaaS examples in this category are Microsoft Azure Functions, Amazon Lambda, etc.

  • Containers as a Service (CaaS): It offers container-based virtualization that allows IT teams to deploy, run, and manage containers and collections. This becomes useful for ensuring consistent experience during the creation of fragmented applications. Examples are Azure Container Instances (ACI), Portainer management tool, Amazon Elastic Container Service (ECS), etc.

  • Network as a Service (NaaS): Cloud providers enable their clients to rent networking services through virtualization of network infrastructure. This helps businesses have global coverage for their operations without having to build networks on their own.

  • Database as a Service (DBaaS): This service model provides businesses with the ability to set up and run databases without any physical installation or performance configuration. This way, the actual subscriber does not have to perform administrative or maintenance tasks. One such example is Oracle Database.

  • Storage as a Service (StaaS): The vendor manages a data storage platform where customers can store their data and ensure easy scalability. Options include storage objects, network file systems, raw storage volumes, and more. HPE Greenlake and Hitachi STaaS are two such XaaS examples.

  • Security as a Service (SECaaS): Some businesses also opt for security from a third-party provider instead of doing it on their own. In this outsourcing, the vendor integrates their security capabilities to suit the infrastructure of a particular business.

  • Backup as a Service (BaaS): In contrast to traditional on-prem backup, businesses which adopt cloud often opt for this service. The service vendor has to ensure reliability and management of back up data. It is important for businesses to archive data and achieve legal compliance.

  • Monitoring as a Service (MaaS): In this delivery model, third party vendors deploy their solutions to monitor business applications and other services in the cloud owned by their customers. The purpose is to secure all the IT assets of a business at any point in time.

    Industry specific XaaS examples like Healthcare as a Service and Marketing as a Service are also coming up. As smart cities grow at an accelerated pace, the importance of XaaS in IoT (Internet of Things) will also rise.

Disadvantages of XaaS Model

There are some drawbacks of XaaS model due to which businesses become hesitant to adopt it. Primary disadvantages are:

  • Dependence on Internet: XaaS is based on accessing IT resources via the Internet. Poor internet connection can make it difficult to access these resources. Businesses must check the SLAs (service level agreements) of the providers to ensure the uptime of services.

  • Provider Dependence: While XaaS reduces the burden on in-house IT staff, users depend on the provider for visibility into the actual environment. Choosing a reliable XaaS provider is crucial as provisioning and management of resources is completely dependent on him. Any changes in the provider’s plans around the service can have a significant impact on the client operations.

  • Traffic Congestion: As adoption of XaaS increases, the increase in simultaneous demand results in performance degradation. It is common to have latency, storage, bandwidth, and other issues.

  • Security: As the management of the solutions and services is done by third party vendors, the security of the organization’s data is not in their control. However, if businesses take due care of the security practices followed by XaaS providers, they can reduce their risks by selecting the most reliable vendor.


Whether you choose private, public, or hybrid cloud, you can avail XaaS capabilities and have an easily scalable modern work environment.
