Currently, cloud service is an increasingly popular way for technology companies to access IT infrastructure, software, and hardware resources, as well as these services, are usually set up in order to help different business and research. Theoretically, A cloud service is accessible to users on demand via the Internet from a cloud computing provider’s servers as opposed to being provided from a company’s own on-premises servers. Moreover, cloud services offer easy, scalable access to applications, resources, and services plus, a cloud services provider manage them entirely. Additionally, Information and data are kept on physical or virtual servers that are maintained and controlled by a cloud computing supplier.
There are different types of Cloud Services available in the market. We tried to break it down in details below.
Infrastructure as a Service (IaaS)
Infrastructure as a service (IaaS) is the most bottom level of cloud solution. It is a form of cloud computing that consist of outsourcing the equipment used to support operations. Of course, this includes storage, hardware, servers, and networking components, all of which are available over a network.
The benefits of Infrastructure as a service (IaaS):
Business Agility is the skill to arrange resources in less time, enabling the infrastructure size to match demand. Moreover, in an e-commerce website, there we need various types of demand loads every day it can be a support. Moreover, it also increases stability, reliability, supportability that means with Iaas there is no need to maintain and upgrade software and hardware.
Focus on priorities – that means Iaas allows you to scale your business. When one moves the infrastructure to a service based model, organizations are able to focus their time and resources where they belong.
Moreover, we can reduce the cost in many ways, like by moving from Capex to an OPEX model, providing a consumption-based approach to IT rather than paying of IT hardware over a three year period with a greater chance of obsolescence during the term.
Examples: Amazon EC2, Windows Azure, Rackspace, Google Compute Engine.
Platform as a Service (PaaS)
Platform as a service (PaaS) is a cloud computing model in which a third party provider delivers software and hardware tools. Of course, these are needed for applications development to users over the internet. It also describes a computing platform that is delivered as an integrated solution. The solution stack may deliver an OS, middleware, database or application.
The benefits of a platform as a service (PaaS):
Focus resources with PaaS many of the tasks associated with the development of software solutions are handled by the PaaS provider. These tasks include management of the platform, deployment of the platform, security, and others. That means for a PaaS solution, IT team don’t need focus.
Using PaaS as a cloud helps you to stay up to date. You can build your own development platform using this cloud. You can regularly maintain, track and update your components which is extremely important.
One can achieve Maximum uptime using Paas as a cloud. PaaS providers make use of a high level of experience at keeping their platform up and running. Besides, you will not be available if you are managing your own development platform.
Examples: AWS Elastic Beanstalk, Microsoft Azure, Heroku, Force.com, Google App Engine,
Software as a Service (SaaS)
Software as a service (SaaS) is a software distribution model through which applications are presented by a retailer or service provider and made accessible to customers over a network, usually, the internet. It is a natural evolution of software. SaaS is closely related to the application service provider (ASP) and on-demand computing software delivery models. Hosted software or on-demand software is the other naming variation of SaaS.
The benefits of software as a service (SaaS) :
Automatic and Easy updates are the key benefits of SaaS, the SaaS providers deal with the software and hardware updates. Rather than purchasing new software customer can rely on a SaaS provider to automatically perform updates and patch management.
Users can access SaaS servers from any internet enabled device and location.
SaaS offers high vertical scalability that gives customers many options like to access more or fewer, services or features on – demand.
SaaS application is already installed and configured in the cloud. This minimizes common delays resulting from often lengthy traditional software deployment.
When customers subscribe to a SaaS offering they pay for this service on a monthly basis using which brings down fees for hardware and software maintenance. Moreover, users can also terminate SaaS at any time to stop those recurring costs.
Examples: Google Apps, Microsoft Office.
Recovery as a Service (RaaS)
Recovery as a service (RaaS) is one of the cloud computing services. In any small to medium scale companies, RaaS is one of the most important factors especially when the company serves lacs of customers they intend and expect to run effectively and incessantly. Furthermore, RaaS is imperative that the customers receive uninterrupted services in the face of any unfortunate event. People also refer to it as Disaster Recovery as a Service (DRaaS). There are three types of RaaS models-To cloud RaaS, From cloud RaaS, In cloud RaaS.
The benefits of Recovery as a service (RaaS):
In a company, if disaster might occur, each second the power is out of servers means huge losses for the organization with a DRaaS solution in place, the company should not have to worry about this because you will be able to restore normal operations within minutes. A team of DRaaS professionals will handle your account. Depending on the provider you choose, 24 x 7 x 365 services might be available.
With DRaaS an organization can quickly and reliably restore one virtual machine and the entire data center.
With cloud-based DRaaS solutions, you only pay for what you used. If you like to improve your services and needs increase over time you can upgrade your service quickly.
Data protection for hardware causes one of the biggest costs of data recovery, When you move to a DRaaS solution, your service provider is responsible for hardware-related data protection.
DRaaS is more flexible if you compared with the other traditional methods of backup. There are various DRaaS services that offer you more options and that will help you to handle different business systems.
For starters in house disaster recovery programs are costly, because of the recurring costs for maintenance and IT support. The DRaaS illustrate an investment for your business that will minimize costs over a long time.
Moreover, DRaaS is a cloud-based solution that will help you be able to access your system from any location which has an internet connection. You will do business from any location if a natural disaster makes your office unusable.
Examples: Acronis, Amazon Web Services, Axcient, Bluelock, Databarracks, EVault, IBM, Iland, Infrascale, Net3 Technology, Peak 10, Quorum, Rapidscale, Sungard Availability Services (AS), Unitrends, Verizon Communications, VMware, Windstream Communications and Zerto.
In conclusion, cloud services are now new technological phenomena that have the potential for a great impact on the web world. Furthermore, these services are to meet the demands of its users’ by providing access to software, storage, compute and other IT infrastructure elements without the hassle of maintenance.
