4 Categories of Cloud Computing Architecture

What is cloud computing?

Cloud computing refers to the process of sharing and accessing data over the Internet instead of on your local hard drive or server. Cloud computing may be used for data storage, software, analytics, accessing remote servers, and other computer services and commands.

Cloud computing has become very popular due to its ability to save space, share information between computers, and safely store vast amounts of data without the fear of losing it due to an unforeseen technical issue. Using cloud services is also faster than using a local hard drive, since commands are all performed through network connections. Cloud computing services also continually update their hardware systems, making sure that you always have access to the most current and top-of-the-line technology and programs.

SaaS – software as a service

SaaS, which stands for “software as a service,” is one of the most popular forms of cloud services and refers to cloud operation software that is provided for a subscription fee to clients over the Internet. This software is most often licensed to costumers as an on demand service. Depending on the business model and revenue made by advertising, SaaS can also be provided to customers free of charge.

SaaS companies manage the software at a central server, as well as handle all required patches and updates. Since the SaaS provider handles these requirements, clients do not have to bother with coding, keeping the software up-to-date, or software or hardware maintenance. The software can be accessed via a web browser, which frees up room on your computer. Average consumers and companies that rely on frequent field sharing, social networks, and email, among other software services, often use SaaS on a consistent basis.

SaaS services include email services, such as Outlook or Hotmail, as well as other types of online applications. These email providers are accessed through a web browser and stores your messages on a central server.

SaaS is especially popular with developers, as it allows them to work on developing applications without the need for managing a local server and other types of maintenance.

DaaS – development as a service

DaaS, which stands for “development as a service,” refers to a type of cloud service that provides applications used by software developers. Since the services are provided over the Internet from a central location, DaaS allows developers to work as a team from different areas. Developers paying for DaaS will also have access to the latest technology, since the service provider consistently updates the cloud applications.

DaaS has become especially useful for banks and other companies working in the financial industry, since it provides several advantages, such as increased security and access to the most current and efficient types of software, as well as important financial trends and information. Banks can also use cloud applications to manage employees and oversee operations at different branch offices.

PaaS – platform as a service

PaaS, or “platform as a service,” allows users to manage, run, and develop different applications without having to build or manage their complex infrastructure system. The customer is able to use the software with little configuration, while the provider uses a public cloud service for hosting the application.

PaaS allows developers to design, test, and run their newly created software on platforms their customers will use once the product is complete. Platform as a service also lets the developers test their software on multiple platforms at once without the need for changing their code. PasS is an especially useful tool when multiple developers are working on the same project, since it allows access from various locations.

IaaS – infrastructure as a service

IaaS, or “infrastructure as a service,” provides cloud computing infrastructure services on an on-demand basis. This means that users can have access to operating systems, data storage, servers, and network systems through the cloud, instead of having to buy and make room for expensive hardware and other types of computing equipment.

IaaS providers make sense for developers that are just starting out and can’t afford expensive physical hardware. IaaS can also provide infrastructure services for temporary projects without the need of making permanent investments in hardware.

Cloud Computing: a growing industry

With so many different types of cloud computing available, it is important to understand the mechanics of each service and decide which one would be best for your particular needs. The world of computer science and other related fields are using cloud-computing services to make significant advancements in software development.
