Cloud computing is a rapidly expanding industry that has revolutionized how organizations handle their IT infrastructure and applications. With more and more companies moving their storage and computing needs to the cloud, it is important to understand what exactly constitutes a cloud service. This article provides a comprehensive overview of the different types of cloud provider available, along with their key benefits and practical implementations.
Infrastructure as a Service (IaaS)
IaaS or Infrastructure as a Service provides fundamental compute, storage and networking capabilities on-demand in a self-service manner. Through IaaS, users can deploy and run various operating systems and applications without investing in their own physical servers, storage systems or network components. Popular IaaS platforms include Amazon EC2, Google Cloud Platform and Microsoft Azure which provide basic storage, computing and networking building blocks in the form of virtualized resources. Users pay only for what they use, making IaaS ideal for scaling applications rapidly up or down depending on demand levels. Key benefits of IaaS include reduced upfront infrastructure costs, high scalability, disaster recovery options and pay per use pricing model. Many organizations use IaaS to host web applications, databases, backup and storage in the cloud.
Platform as a Service (PaaS)
PaaS or Platform as a cloud Service moves the abstraction level higher than IaaS by delivering a development platform with integrated services for building, testing, and hosting applications. Prominent PaaS offerings include Heroku, Google App Engine and Azure App Service which provide database services, programming languages, analytics tools etc. as a holistic platform to develop and operate applications. Users can focus purely on their application code without worrying about infrastructure management. PaaS allows faster development cycles, easy scaling and collaboration features. PaaS is suitable for developing cloud native applications quickly without devoting time to system administration tasks. Popular examples are mobile backends, microservices architectures and web applications using PaaS integrated tools and services.
Software as a Service (SaaS)
SaaS or Software as a Service provides complete software solutions delivered as an online service on a subscription basis. Well-known SaaS examples include G Suite, Microsoft 365, Salesforce and Workday Financials which deliver productivity, CRM and finances apps entirely through the internet. Users access SaaS services through a web browser or mobile app without needing to install or run specialized software locally. Key benefits are low upfront costs, automatic updates, flexible scalability and simplified IT. Widely used SaaS categories are office suites, CRM, ERP, SCM, communication tools etc. Organizations leverage SaaS for reducing software costs, gaining faster access to latest features or replacing custom on-premise solutions.
Desktop as a Service (DaaS)
DaaS provides virtual desktops hosted on cloud servers which can be accessed from any internet-enabled device. Users experience their desktop in a browser without needing physical PCs. Popular DaaS products are Amazon WorkSpaces, Citrix Virtual Apps and VMware Horizon. Virtual desktops give users familiar desktop OS experience either through dedicated VDI instances or shared desktop pools while centralizing management and upgrades in the cloud. DaaS delivers benefits like secure remote access, BYOD support, device independence and better disaster recovery. Use cases span call centers, healthcare workers, remote employees and educational institutions requiring centralized desktop infrastructure.
Serverless Computing
Serverless computing provides a ‘Function as a Service’ model where the cloud provider runs the servers and manages scaling infrastructure. Users only write necessary code logic without needing to think about servers. Popular serverless platforms are AWS Lambda, Google Cloud Functions and Microsoft Azure Functions. Users pay only for the compute time required for code execution. Serverless computing boosts developer productivity through simplified deployments, automatic scaling and pay per invocation costing. Common applications built on serverless computing are IoT backends, microservices, webhooks processing and workflows automation through event-driven serverless architecture.
Benefits of Cloud Services
Key organizational benefits of adopting cloud provider models include:
– Reduced capital expenditure – No upfront investment on servers, networking or data center infrastructure. Switch capex to more flexible opex.
– Agility and speed of deployment – Rapid provisioning of IT resources from virtually unlimited cloud pools leads to faster deployment times.
– Scalability – Cloud provider easily auto-scale up or down as per demand without capacity issues. Ensure optimal resource utilization at all times.
– Lower IT costs – Less capital spending on hardware, no need for large support staff, pay per use pricing cuts wastage. Lower TCO overall.
– Mobility – Access apps and data from anywhere using internet-enabled devices with cloud mobility capabilities.
– Innovation – Faster experimentation using cloud provider encourages new ideas/products. Easier collaboration through integrated platforms.
– Disaster recovery – Geographic distribution of infrastructure and automated replication ensure business continuity. Fault-tolerance capabilities.
Widespread adoption of cloud computing across industries is driven by these compelling economic benefits compared to traditional data center hosting models. Gartner predicts that by 2022, over 75% of all databases will exist on public cloud platforms worldwide.
Implementing Cloud provider Successfully
While cloud provider provide clear advantages, their adoption demands careful planning and management. Key aspects organizations should focus on include:
– Understanding workload requirements and selecting right cloud service model – IaaS, PaaS or SaaS. Hybrid cloud also an option.
– Ensuring regulatory/compliance needs are met through appropriate provider certifications like HIPAA, PCI-DSS etc.

In Summary, cloud provider refer to on-demand delivery of computing resources over the internet. These resources include servers, storage, databases, networking, software, analytics, and intelligence. There are three main types of cloud provider: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
