Cloud computing is one of the fastest-growing technology trends of the past decade. As such, it can spark a lot of discussion and debate. There are three main cloud service models: public cloud, private cloud, and community cloud. There are also several technologies that enable cloud computing like software as a service, platform as a service — and even infrastructure as a service. The deployment models are also different: private cloud focuses on security (as in the physical location of data), community enables socialization between customers and vendors, and hybrid combines aspects of other models while trying to solve their limitations.
The variety of cloud service models and deployment models may leave you with some questions regarding the differences of each, how to know which meets your business needs, and how each utilizes different cloud computing resources. Start with our short guide to learn more about top cloud service and deployment models.
Cloud Service Models
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model provides capabilities to users across a range of industries including retail, education, and healthcare.
In the cloud computing model, software applications and information are stored on remote servers rather than on devices kept by individuals. Cloud computing gives users more flexibility in what they do with their devices since they don’t have to worry about installing programs or updating devices.Depending on your business requirements, you can choose from a variety of service models and deployment models that suit your needs best. Here are some of the most popular ones:
Software as a Service (SaaS)
You’ve probably come across this term a lot. SaaS is where you use software hosted by someone else. This model is suitable for small-to-medium sized businesses who need access to software without having to worry about maintenance or infrastructure costs. Examples include Microsoft Office 365 and Salesforce.com.
Platform as a Service (PaaS)
PaaS offers application development tools and runtimes that make it easier for developers to build applications on top of the platform provider’s infrastructure. It also makes it easier for developers who are not familiar with server administration tasks such as operating system configuration or network management to create applications quickly because they do not have to worry about installing or configuring servers themselves. Examples include Google App Engine, Heroku, OpenShift, Red Hat OpenShift Online, Microsoft Azure App. PaaS also includes managed services like backup, scalability and security that developers don’t need to worry about when building their apps.
Infrastructure as a Service (IaaS)
IaaS is a cloud computing delivery model in which customers deploy virtual machines (VMs) and other resources on-demand using self-service portals. IaaS providers rent out computing power, storage space, and other IT resources over the internet without customers having to invest in hardware or software themselves.
Functions as a Service (Faas)
There is so much potential in the future of Faas cloud computing services. Unlike before, companies will be able to focus more on innovation and growth rather than dealing with infrastructure upgrades. This awesome cloud computing service can help out both small to large companies and make their operation cost efficient. FaaS is a boon for companies under regulatory compliance constraints in terms of adhering to data privacy regulations by country. The increased focus on customer needs and data protection is not just favourable for businesses but also beneficial for the end users.
Cloud Deployment Models
There are 4 main cloud deployment models. Cloud deployment models are simply a specific configuration of parameters, for instance, accessibility, and proprietorship of the deployment size and infrastructure. Deployment types vary on who has control over the infrastructure and where it’s located. Here are 4 models to consider when choosing a model that fits your computing, storage, and networking requirements and of course, business goals:
This is a cloud model where a vendor provides services to anyone who wants to use them. The vendor can be public or private, but in either case it offers its services to all comers. Public clouds are typically owned and operated by large companies such as Amazon Web Services (AWS), Google Cloud Platform (GCP) and Microsoft Azure.
This is a cloud model where only specific users can access the resources provided by a vendor, which may be public or private. Private clouds are typically used by smaller companies with fewer technical resources available to them than their larger counterparts.
This is a hybrid between public and private cloud models that allows multiple companies to share resources from one another’s servers while maintaining some level of control over their own data security policies and procedures. Community clouds are used mostly by organisations with high security concerns who don’t want to share their data with anyone outside their own company.
This model combines aspects of both public and private clouds by using a combination of both types of infrastructure to deliver services to customers or employees.A hybrid deployment uses multiple models at once, such as public and private clouds being co-located on one physical platform or two different ones connected through virtualization technology.
There is no clear winner when it comes to the service models offered by these cloud vendors. All of them have their strong points, and each is being picked up by new clients at a pretty rapid pace. It’s hard to go wrong with any of them, but as always, you should weigh your own needs accordingly and figure out which one is best based on where you think you’ll be in three years. You may also want to look into local options to keep costs down or for other reasons.There are many players in the cloud services market, each with a unique model and way of approaching the cloud. The cloud is continuing to grow and develop, with new players entering the market frequently. There have been few studies conducted that have attempted to categorise these models, which has led us to do so based on our own experience in the field. Hopefully, you’ll find this information useful if you decide to explore these different models for yourself in more detail.
