Types of cloud and cloud services

Types of cloud and cloud services

The cloud is a way to get the right amount of resources virtually on demand without investing in new hardware or software. Customers pay a fixed price to the cloud provider or only for the resources they use.

By filling out the online form, users can create an account and run virtual servers or give resources to new applications.

There are different kinds of clouds we will consider them and dwell on each one in detail:

SaaS – software as a service

This type of cloud delivers applications over the Internet through a browser. The most popular applications of the SaaS type are Google G Suite: Google Docs, for example, and Microsoft Office 365. Typically, SaaS applications offer advanced configuration options and development environments.

IaaS – infrastructure as a service

At the basic level, IaaS providers offer storage and computing services on the “how much I used – how much I paid” model.

The full range of services offered by major cloud providers includes highly scalable databases, virtual private networks, large data analytics, development tools, machine learning, application control.

Among leaders of this type of cloud are Amazon Web Services, Microsoft Azure, Google Cloud Platform, and IBM Cloud. VPS.ua also provides a cloud type IaaS with PaaS elements

PaaS – platform as a service

Providers of PaaS type provide services tailored for developers. Salesforce Heroku and Force.com are popular cloud providers like PaaS.

For companies, PaaS providers can ensure that programmers have ready access to resources and certain services, while the back office will support the infrastructure that underlies them.

FaaS – function as a service

FaaS is the equivalent of serverless computing in the cloud. It adds another level of abstraction to the PaaS type. It means that programmers are isolated from everything below code.

Instead of messing with virtual servers, containers and the development environment, they can load function blocks of code and configure them to trigger a specific event – when a form is sent or a file is downloaded.

The advantage of FaaS applications is that they do not consume resources until a customized code trigger is triggered. This reduces costs.

Private Cloud

A private cloud reduces the amount of technology used for IaaS public clouds. The result is that it becomes software that can run and run in the customer’s data center.

Like a public cloud, customers can dedicate virtual resources to build, test and run applications.

For technicians, the private cloud is as automated as possible. They barely have to add or manage resources manually.

Hybrid Cloud

Hybrid cloud – private cloud integration with public cloud.

In its most advanced version, a hybrid cloud creates parallel environments. In these environments, the client is free to move applications between the private and public cloud.

In other hybrid cloud options, databases can remain in the client’s data center and integrate with public cloud applications.

Public API – application software interfaces

Public APIs give programmers the functionality of an application to which they have software access.

For example, when programmers create web applications, they often turn to the Google Maps API to provide users with a map. To integrate social networks into an application, developers can access the Twitter, Facebook or LinkedIn API.

Any business can provide their API so that customers can access the functionality of the application.

iPaaS is an integration platform as a service

Data integration is important for all large companies – especially those that use the SaaS model in a scalable manner.

iPaaS providers typically offer pre-built connectors to distribute data between popular SaaS applications and local company applications.

Typically, cloud providers such as iPaaS focus on the Business for Business segment, the integration of online stores.

IDaaS – identity as a service

The biggest security problem in the cloud is the user’s identity, rights and permissions that they have in private and public cloud data centers.

Providers like IDaaS maintain user profiles, identify users and grant access to resources or applications based on security policies, user groups and individual rights.

Okta is the leader in the IDaaS cloud structure. CA, Centrify, IBM, Microsoft, Oracle, and Ping provide local and cloud solutions.

Collaboration Platforms

Products for team collaboration – Slack, Microsoft Teams and HipChat – have become essential platforms on which colleagues can communicate and work.

These are quite simple applications like SaaS that support chat, file transfer, audio and video communication. Many of them provide APIs to simplify integration with other systems and allow programmers to create and share add-ons that improve existing functionality.

Vertical Cloud

Vertical cloud providers provide companies with applications with functionality and resources tailored to the business domain.

For example: a healthcare product will have the tools to handle electronic medical records or medical imaging.

Cloud security

The main claim to the cloud is a security problem. Although large cloud providers show that they are much less likely to suffer from attacks than average data centers.

A more significant issue is the integration of security policies and user profile management between clients and public cloud providers.
In addition, sometimes national laws prohibit customers from giving sensitive data away.

Benefits of the Cloud

The main advantage of the cloud is that it reduces the release time of applications that need to be dynamically scaled. In addition, new tokens are constantly appearing in the cloud that you can embed in applications: machine learning, Internet connectivity of things. The cloud also provides a microservice architecture.
