Description: You have heard the term “cloud service”. So what exactly is cloud services, and how does it work? And the complexity of the infrastructure contained within it.
Cloud service or cloud computing is a cloud backup solution that allows businesses to store data on the Internet instead of locally stored on physical disks. Cloud services is a computer model that uses computer technology and is based on the Internet. In this model, all information technology are provided in the form of “services”. Users don’t need the knowledge or experience of the technology, there is no need to pay attention to the infrastructure that serves that technology.
According to the IEEE Computer Society, “Cloud service is a pattern in which information is stored permanently at servers on the Internet and is only stored temporarily in clients, including personal computers, entertainment centers, corporate computers, handheld computers,…”. Cloud service will allow customers to remotely access the service provider, use secure login application to back up files from host system or data center to online storage server, and this connection is encrypted.
What is cloud service?
Storage and backup of data for cloud service
Cloud service has many data storage services such as Drop box, Google Drive, SkyDrive (of Microsoft), … These services give users a few Gb space. Users will download the software, after installation, the software will synchronize with your computer. When you copy a file to a partition (eg Drop box) on your computer, the system will automatically download the file to the drop box’s server (automatically encrypted data). When you edit a file, the server will also edit itself.
Backup as a Services solution – BaaS
For enterprises, BaaS is offered as a maximum security solution for data systems for the purpose of replacing the entire physical data system or add essential features of data storage and then restore them when disaster strikes. Cloud service’s storage features meet the rigorous business requirements for data retention and are part of a company’s disaster recovery plan. BaaS helps ensure that data remains secure if local business data systems are endangered by natural disasters such as fire, flood, hacker attacks or theft of internal information.
3 major service models of cloud service
Cloud service models
1. SaaS: Software as a Service
You rent and use the software on the cloud service such as Microsoft 365, Saleforces.com, ERP, CRM, Cisco Jabber, Games… You don’t need to know how to set up the system, all you need to know is that they provide the service according to the needs of the business you need and use it.
2 Pass: Platform as a Service
If you need a website, need a web server, mail server… What do you do in case you do not have a data center, an IT team to manage, operate…? You just need to rent mail hosting, web hosting, database hosting… Paas brings convenience to users without the need to invest in infrastructure and quickly deploy an IT system that meets the needs of the business. You do not have to think about what equipment to choose: firewalls, storage… And cloud service flexible increases according to the needs of the business.
3. IaaS: Infrastructure as a Service
This model allows IT to build infrastructure, storage, network … but it is not on-premise but on the cloud. You rent a public cloud service and install yourself, build policies, and access privileges such as Windows Server, Linux, Network, Storage, Database, Security, with full virtualization. These servers and systems are fully hosted and charged through the lifetime of the user.
Here are some of the most basic and practical concepts of cloud service.
