To provide computing services such as servers, storage, databases, networking, software, and analysis through the Internet (“the cloud”).
The company that provides these computing services is called a cloud provider, and the cloud provider typically charges cloud computing services based on usage, similar to how households are charged for water or electricity.
With cloud computing, you can use online services to send mail, edit documents, watch movies, watch TV, listen to music, play games, and store photos and other files. The evolution of cloud computing means creating new apps and services, regardless of business size. From small to very large projects such as data storage, backup and multiple website and blog hosts, audio and video streaming, on-demand software creation, It is flexible enough to run.
Cloud Service Types
Most cloud computing services are IaaS, PaaS and SaaS. Built as these cloud computing services, it is also called cloud computing spec.
IaaS – Infrastructure as a Service
As the most basic computing cloud service, this is a server using the main server, VM, storage, network and other IT infras.
Through the Internet, this is a server utilizing pro-vision and others to quickly expand scale, allow for scale up and down based on the fees used.
Acquiring server, data center infrastructure and maintenance allows for the loss of confusion and additional fees.
Every resource service is provided, and special resources will be applied with fees.
Our CSP, cloud services provider, will maintain the infrastructure, and the user will maintain only the actual software.
Common IaaS business scenario
Advantages of IaaS
PaaS – Platform as a Service
PaaS is designed to make it easier to develop web apps or mobile apps for developers based on necessary servers, storage, network and infrastructure of database.
It is an environment inclusive of resources to allow for development of simple cloud apps to enterprise application programs.
In addition to server, storage, networking and infrastructure, it also includes middleware, development tools, business intelligence service and maintenance of databases.
It is designed to allow for build, test, distribution maintenance, update, making it a full service program.
In addition to acquiring resources for software license, basic application program, infra as well as middleware, you will be able to reduce costs significantly.
The user will maintain the developed application program, and the cloud service provider (CSP) will take care of everything else.
PaaS Business Scenario
Advantages of PaaS
SaaS – Software as a Service
With SaaS, we help manage software applications and basic infrastructure to host, manage, upgrade, and maintain security patches.
It is a complete software solution that you buy on a pay-per-view basis, providing cloud-based apps for your organization, and app users using their web browsers to access those apps over the Internet.
Examples include e-mail, calendaring, and applications for Office documents, and are increasingly being extended to various business applications such as ERP and CRM.
All underlying infrastructure, middleware, app software, and app data are located in the service provider’s data center. Service providers manage hardware and software, and ensure service and application availability and security.
