With the rise of computers, there was a significant need for interacting with sharing data and information. So, the server technology was introduced.
Servers:
Basically, a server is a computer program or a computing device that provides a service to another computer/computer program and its user also known as the client. In a data centre, the physical computer or the computing device that is used to provide the hardware to run the server program is also known as the server.
Traditional servers will need physical data centres and a lot of space for their operations. So, building a servers system need both financial capital and many software and hardware component gathering that takes a lot of time.
Advantage of Traditional Server architecture:
- total control over hardware and software systems that the client uses.
- can provide a higher level data protection since data is maintained on-site.
- data is maintained offline networks as the process doesn’t need internet.
Cloud computing:
Cloud computing is an emerging technology that leverages the Internet to offer computing services such as applications, storage, and various resources. By utilizing these services, companies can access software applications and services from one central server, reducing expenses on the management and upkeep of software. it is basically a on-demand provisioning of computing resources like servers, storage, databases, networking, software, and analytical services. Cloud computing has become a favoured choice for individuals and companies, providing benefits such as cost reduction, enhanced productivity, greater speed and efficiency, improved performance, and better security.
advantages of cloud computing:
- The removal of failure single points increases the resilience and scalability of cloud computing.
- You get access to almost limitless servers and storage capacity.
- Your IT infrastructure maintenance is reduced by cloud computing every item is a service.
storing data:
In cloud computing, the data is stored remotely in virtual space known as the cloud. Businesses offering cloud services allow users to store files and applications on external servers, making it possible to access all data online. Data, work, and applications belonging to individuals or companies can be accessed from any device with an Internet connection. Cloud computing can be categorized as either public or private. Public cloud services offer their functionalities online for a charge. Private cloud services cater only to a limited group of users. These services consist of a network system that delivers hosted solutions. Additionally, there is a hybrid option that merges both public and private services.
Application services of cloud computing:
- Email services
- data storage, back up and retriaval
- Creating and testing apps
- Data Analytics
- Audio and video streaming
- software on-demand services
There are three major cloud computing platforms.
- Software as a Service (SaaS): involves the licensure of a software application to customers. Licenses are typically provided through a pay-as-you-go model or on-demand. (Example: MS 365)
- Infrastructure as a Service (IaaS): delivers everything from operating systems to servers and storage through IP-based connectivity as part of an on-demand service.
- platform as a Service (PaaS): is considered the most complex of the three layers of cloud-based computing. PaaS shares some similarities with SaaS, but instead of delivering software online, it is a platform for creating software delivered via the Internet.
