Cloud Computing services are changing the way information technology is being utilized by private companies and public institutions. Today, there is a range of cloud computing services to fulfill practically any IT requirement. Organizations normally pay just for the cloud service they use, helping them decrease running expenses and run infrastructure more effectively.
With every organization today getting into the cloud world, it is necessary to understand the various types of services cloud computing offers. There are lots of types of cloud computing services, all these services have a few fundamental features and benefits in typical and can be classified into 4 basic cloud service offerings. Organizations can fly their business, small or big, to the cloud with these 4 different kinds of cloud computing services:
1. Infrastructure as a Service (IaaS)
The lower end of managed cloud computing services where hardware resources are offered by an external service provider and managed for you. IaaS supplies users access to computing resources such as networking, processing power, and information storage capability.
IaaS helps users to utilize computing power or virtual machines without labor-intensive hardware financial investments or server management. Physically, the hardware resources are pulled from a variety of servers and networks distributed across different data centers, all of which are managed and maintained by the cloud company.
For example, say a user desires a Linux system, with IaaS he will get access to it without having to fret about the networking of the device on which Linux is set up or the physical system.
IaaS is helpful for customers who want to create cost-effective and highly scalable IT services where the costs and intricacies involved in handling hardware resources are outsourced to a service provider. Most of the IaaS plans include servers, storage, virtualization, and networking elements while the users are responsible for setting up and keeping databases, OS, applications, and security components.
Example of IaaS: Amazon EC2, Windows Azure, Rackspace, Google Compute Engine.
Features and Advantages of IaaS Cloud Computing Service
- A common infrastructure as a service offering saves both time and money as the underlying hardware setup and assistance is provided by the service provider.
- Resources are available on-demand as and when required so there is no waste of any unused resources and no hold-ups on including any resources.
- Utility-based pricing design i.e. pays only for the resources you in fact utilize.
2. Platform as a Service (PaaS)
Apart from just offering the IT infrastructure, PaaS also supplies the computing platform and service stack as a service. PaaS is a cloud computing service that offers developers a framework that can be utilized for building custom-made applications.
A typical Platform as a Service offering includes:
- Hosting Solutions
- Software tools for style and development
- Environment for server-side scripting
- Network Access
- Server Software
Examples of PaaS solutions consist of Microsoft Azure, AWS Elastic Beanstalk, Force.com. by Salesforce, Google App Engine, Rackspace Cloud Sites, OpenShift, and Apache Stratos.
Features and Benefits of PaaS Cloud Computing Service
- PaaS makes software development simple even for non-experts as anybody can develop an application through the web internet browser with just a single click performance.
- There is no requirement for the users to update the infrastructure or upgrade as the PaaS provider manages all the upgrade spots, upgrades, and routine software upkeep.
- PaaS provides place independence as developers in different locations can collaborate on the same application development.
- There is no need to purchase physical infrastructure or the knowledge needed to manage it. The ability to rent virtual IT infrastructure brings in terrific expense advantages for the users.
3. Software as a Service (SaaS)
A special cloud computing service that incorporates both IaaS and PaaS service offerings. SaaS is a cloud computing service that supplies application-level services customized to diverse service needs such as business analytics, CRM, or marketing automation. SaaS is a cloud computing service offering that offers web-based software applications to customers on-demand. SaaS providers host a completely functional application through a browser-based interface and make it accessible to the users through the Web.
SaaS offerings permit the cloud to be leveraged for software architecture consequently lowering the overhead of assistance, maintenance, and operations as the applications operate on systems belonging to the vendor. SaaS is the most familiar cloud computing service offering as users frequently connect straight with SaaS applications like Netflix, Gmail, JIRA, Dropbox, or Salesforce.
SaaS is a subscription-based offering where users sign up for software on a regular monthly basis instead of buying it so there are no advance expenses included. When it is no longer required, it also supplies a provision to the users to end the membership.
Examples of SaaS services include SAP Business ByDesign, Zoho CRM, AppDynamics, Microsoft Office 365, Pardot Marketing Automation.
Features and Benefits of SaaS Cloud Computing Service
- There is no initial setup cost as the users can use the application as quickly as they subscribe. Since the processing power is provided by the service company, there is no hardware cost as well.
- Flexible payments as the users spend for the services on a pay-as-you-go design.
- Any updates to the software are automatic and free of charge.
- SaaS offers cross-device compatibility since SaaS applications can be accessed through any internet-enabled gadget, such as a smartphone, desktop, or laptop.
- Enterprises need not engage an IT specialist to download the software on several systems in the workplace nor have to fret about keeping the software up-to-date on every PC.
4. Functions as a Service (FaaS)
Before we understand Functions as a Service, it is important to understand the most popular tech term related to FaaS- serverless computing. Serverless computing is a cloud computing design that removes low-level infrastructure choices and server management from the developers. The application designer need not deal with the allocation of resources as it is managed by the cloud service provider.
FaaS is a new and extremely young cloud computing service serving as a game-changer for numerous companies. It is a serverless computing idea that lets software developers establish applications and deploy a private “function”, piece of business logic, or action without keeping a server. It increases the efficiency as developers require not to consider server operations since they are hosted externally.
Examples of FaaS include Google Cloud Function, Microsoft Azure Functions, Webtask.io, Iron.io, Open Whisk, and AWS Lambda.
Features and Benefits of FaaS Cloud Computing Service
- Money is never ever lost on inactive resources as users are billed depending on the amount of functionality used.
- Makes developers effective as they can focus more on composing application-specific logic instead of needing to handle the server logistics.
- FaaS code is fault-tolerant and naturally scalable.
Every company can gain from several cloud computing services as they assist to improve efficiency and cut down costs. Companies can adopt one or more cloud computing services based upon their requirements, locations of proficiency, business procedures, and other priorities. A key factor to consider point when choosing a cloud computing provider is to do enough research to comprehend service requirements and find suppliers who can provide preferred cloud services that will work completely based upon the requirements.
