What are some examples of cloud services

What are cloud applications?

A cloud application is a program that a user accesses primarily via the Internet and that is at least partially managed on a server and not on the user's local computer. Strategies for developing cloud-native applications help development teams to develop consistent apps (for front-end users and back-end operations teams) - for all IT infrastructures: physical, virtual or cloud-based.

A Brief History (and Predictions)

However, this simple definition says nothing about how much cloud applications have already changed markets and business models. When well developed, cloud applications offer a user experience like any other program installed on a local machine, but with much lower resource requirements, easier updates, and the ability to access functions from different devices.

New cloud applications can become important sources of income and lead to disruptive changes in markets and business models. Gartner forecasts global cloud services revenue of USD 110.5 billion in 2020 and a further increase to USD 143.7 billion by 2022.

Are you interested in cloud applications and would like to integrate an existing app into your existing architecture that should support your teams? Or would you like to develop a cloud app for your customers or for internal use yourself?

Integration of third-party cloud applications into existing architecture

Example Salesforce. This is a well-known cloud application that you can use for Customer Relationship Management (CRM) instead of installing a separate system on your own servers. Red Hat even has a case study for integrating Salesforce.

Cloud applications such as Salesforce, also known as Software-as-a-Service (SaaS), open up new possibilities for integrating useful tools and services into your existing systems. However, you must first check the compatibility of your current architecture.

What designs are there for cloud applications?

Cloud applications are programs that execute processing logic and data storage between two different systems: the client and the server. Some of the processing is performed on the end user's local hardware (e.g. on desktops or mobile devices), and some on a remote server. One of the typical advantages of cloud applications is that most of the data storage is on a remote server. In fact, some of these applications can be designed so that they do not actually consume storage on a local device. The user interacts with the application via a web browser or an API. These are the basic principles of a cloud application. But what exactly is handled between client and server and how this affects the user experience depends on the following options.

SaaS (software-as-a-service)

SaaS is a popular form of cloud computing in which the user is provided with a web application with all of its underlying IT infrastructures and platforms. SaaS is ideal for businesses or individuals:

  • Don't want to manage the infrastructure, platforms and software yourself
  • The challenges of which only require minimal adjustment
  • Prefer the software subscriptions

With SaaS, users can reduce their upfront costs, as ongoing software purchases or investments in a robust local IT infrastructure are eliminated. In spite of all this, it is advisable to purchase fast network hardware, as the service performance depends on the speed of the Internet connection.

Examples of SaaS include customer services such as Google Docs and Microsoft Office 365, as well as business services that provide HR software, content management systems, CRM tools and IDEs (Integrated Development Environments).

PaaS (Platform-as-a-Service)

PaaS is a platform on which you can develop, run and manage your own apps without having to develop and maintain the necessary infrastructure or environment. Because with PaaS, the hardware and software platform of a third party is made available to the user. That means you only control the actual applications and data that reside on the platform, making PaaS the ideal solution for developers and programmers. So z. For example, a developer can use PaaS as a basis to create a new application that can be integrated into an existing Oracle database in your company.

IaaS (Infrastructure-as-a-Service)

With IaaS, the infrastructure (e.g. server, network, virtualization and storage) is managed for you by a provider via a public cloud or a private cloud. You access this infrastructure rented by you via an API or a dashboard. You can manage components such as the operating system, apps and middleware, while the provider (such as AWS or Microsoft Azure) provides hardware, networking, hard drives, storage and servers and is responsible for any failures, repairs and hardware problems.
