What’s Cloud Computing?
Cloud computing refers to the delivery of various computing services over the Internet (the cloud). It provides online data storage, applications, and infrastructure for faster innovation, more flexible resources, and increased efficiency. Cloud services can be demanded on a pay-as-you-go basis.
Cloud Deployment Models
Cloud deployment model is basically a cloud architecture used to implement a cloud solution. A variety of models and services have developed to assist you find the best option for your needs.
- Public Cloud
In this model, a third-party service provider provides cloud services to the public through the internet. The services like storage capabilities, software, and virtual machines are supplied on demand.
Microsoft Azure, AWS, Google Cloud Platform, and IBM are among the most popular public cloud service providers.
- Private Cloud
A Private Cloud can also refer to an Internal Cloud or a Corporate Cloud. It is a set of cloud computing services used solely by one company or organization. Companies use this model to build and manage their own data centers, either internally or through a third party.
OpenStack is popular private cloud technology and provider.
- Hybrid Cloud
This model is a combination of private cloud and public cloud, including orchestration and automation between the two. A hybrid cloud provides your organization with better flexibility and helps optimize your existing infrastructure and compliance by allowing data and applications to flow between private and public clouds.
In a hybrid cloud system, non-essential tasks are managed by the public cloud, while critical tasks are handled by the private cloud.
- Community Cloud
In this model, services are made accessible to a set of organizations to exchange information between the organization and a specific community. A community cloud is owned, maintained, and run by one or more community groups, a third party, or a combination of these organizations.
Cloud Computing Service Models
Infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service are the three main types of cloud computing services. Since they build on top of one another, they’re sometimes referred to as the cloud computing stack.
- Infrastructure as a Service (IaaS)
For organizations, IaaS is the simplest solution. It provides basic resources, including physical machines, virtual machines, virtual storage, and more.
Instead of purchasing and maintaining its infrastructure, IaaS allows a company to shift its hardware to the cloud by renting servers and data storage.
Amazon Web Services (AWS) is one of the most renowned IaaS products.
- Platform as a Service (PaaS)
PaaS is a popular choice for companies that want to develop unique applications without making significant financial investments. PaaS allows a company to access a pre-defined software development platform that can be used to create, test, and run applications.
PaaS solutions include Google App Engine, web servers, and SQL servers.
- Software as a Service (SaaS)
SaaS is the most popular cloud application service, and it’s gradually becoming the most popular way for organizations to access software apps. Various organizations utilize SaaS to gain access to a certain software program stored on a remote server and managed by a third-party supplier.
Workday and Microsoft Office 365 are some of the most well-known SaaS products.
