The Top 3 Cloud Computing Service Models

In addition, with applications hosted centrally, updates can be released without the need for users to install new software. One drawback of SaaS comes with storing the users’ data on the cloud provider’s server. Examples of applications offered as SaaS are games and productivity software like Google Docs and Office Online.

  • Connecting your various cloud service models with your on-premises and public cloud resources can be a challenge.
  • A virtual private cloud is an isolated set of servers within a public cloud.
  • Besides IaaS, PaaS, and SaaS, there are a couple of other types of cloud service models you should know about.
  • Now, everyone can utilize cloud-based platforms for nearly all your systems and processes.
  • Cloud bursting enables data centers to create an in-house IT infrastructure that supports average workloads, and use cloud resources from public or private clouds, during spikes in processing demands.
  • In IaaS, the provider supplies and manages the underlying compute, storage, networking, and other physical IT resources on a self-service, on-demand, and pay-as-you-go basis.

The three standard service models are Infrastructure as a Service , Platform as a Service , and Software as a Service . They are commonly depicted as layers in a stack, providing different levels of abstraction. For instance, SaaS can be delivered on bare metal, bypassing PaaS and IaaS, and a program can run directly on IaaS cloud solutions and services without being packaged as SaaS. Generally, as the cloud service model moves from IaaS to SaaS, more services become immediately accessible to a wider market of users. Often seen as a scaled-down version of IaaS, PaaS gives its customers broader access to servers, storage and networking, all managed by a third-party provider.

Supply Chain Management, Business Intelligence, Enterprise Resource Planning , and Project and Portfolio Management will see the fastest growth in end-user spending on SaaS applications, through 2022. It allows the consumer to monitor the status of their critical applications regardless of location. Ensure that your organization has a proper disaster recovery plan to keep your data safe and accessible. IaaS firms only provide the servers and API, so you must configure everything else.

Cloud Computing Models

Working with a trusted solutions advisor can help you assess your organizations need and develop the right hybrid cloud solution. With a solid strategy, cloud foundation and governance plan, you can achieve more value from cloud. PaaS also makes it easier for you to innovate and scale your services on demand.

Advantages of IaaS

Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear unlimited and can be appropriated in any quantity at any time. If you are looking for a highly flexible, scalable service — while maintaining control of its infrastructure — then IaaS is the right choice for you.

Cloud Computing Models

The various companies providing Software as a service are Cloud9 Analytics,, Cloud Switch, Microsoft Office 365, Big Commerce, Eloqua, dropBox, and Cloud Tran. Identify the level of automation and customization you require – whether it needs to be self-service or fully automated. Check if the PaaS solution is optimized for the language and framework you’re using.

Use Case Solutions

It allows developers to focus on optimizing code and application design, without worrying about code execution as it is handled by the cloud service provider. Serverless helps tackle the problem of allocating cloud compute resources by automating scaling decisions of workload services in line with actual service demand. Efficient allocation and usage of cloud resources lead to better cost savings, by avoiding both waste and loss. With Infrastructure as a Service , a cloud service provider owns and manages the hardware upon which your software stack runs. This can be a great cost-reduction strategy if you’d like to avoid purchasing and maintaining infrastructure.

Cloud Computing Models

PaaS is often the most cost-effective and time-effective way for a developer to create a unique application. Maintaining on-premise IT infrastructure can be costly and labor-intensive as it often requires a significant initial investment in physical hardware. You will also probably need to engage skilled external IT contractors to maintain the hardware and keep everything working and up-to-date. Once you understand your company’s needs and strategic goals, you can choose a model that complements your business outcomes and delivers value to your organization. Make sure your organization has systems and policies in place to promote good security practices.

Cloud Deployment Models: Private; Public; Hybrid; Multi-Cloud

You’re not only paying for the SaaS applications/products — you’re paying for peace of mind. SaaS platforms are ideal for when you want an application to run smoothly and reliably with minimal input from you. Scalable, with different tiers for small, medium and enterprise-level businesses. Another advantage of IaaS is it puts control over the infrastructure back in your hands.

By having these passwords, they are able to read private data as well as have this data be indexed by search engines . Cloud services are considered “public” when they are delivered over the public Internet, and they may be offered as a paid subscription, or free of charge. Architecturally, there are few differences between public- and private-cloud services, but security concerns increase substantially when services are shared by multiple customers. Most public-cloud providers offer direct-connection services that allow customers to securely link their legacy data centers to their cloud-resident applications.

Cloud Deployment Models

Evaluate the service provider’s technologies and service roadmap for development. Ensure their platform and technologies align with your cloud objectives and IT environment. Find out if their service roadmap fits your requirements in the long term. Verify if the cloud service provider complies with recognised standards and quality frameworks. Look for vendors who are accredited with certifications such as ISO 27001.

A hybrid cloud service crosses isolation and provider boundaries so that it cannot be simply put in one category of private, public, or community cloud service. It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service. There is the problem of legal ownership of the data (If a user stores some data in the cloud, can the cloud provider profit from it?). Many Terms of Service agreements are silent on the question of ownership.

Anything As A Service (XaaS)

If an application has a regular and predictable requirement for computing services it may be more economical to provide that service in-house. Explore the latest cloud computing strategies to increase flexibility, optimize costs, and improve efficiency. First, you’ll need to assess the best way to support your application or workload.
